Pedometer-based internet-mediated intervention for adults with chronic low back pain: randomized controlled trial

The Effect of an mHealth Self-Monitoring Intervention (MI-BP) on Blood Pressure Among Black Individuals With Uncontrolled Hypertension: Randomized Controlled Trial

BACKGROUND

Hypertension is one of the most important cardiovascular disease risk factors and affects >100 million American adults. Hypertension-related health inequities are abundant in Black communities as Black individuals are more likely to use the emergency department (ED) for chronic disease-related ambulatory care, which is strongly linked to lower blood pressure (BP) control, diminished awareness of hypertension, and adverse cardiovascular events. To reduce hypertension-related health disparities, we developed MI-BP, a culturally tailored multibehavior mobile health intervention that targeted behaviors of BP self-monitoring, physical activity, sodium intake, and medication adherence in Black individuals with uncontrolled hypertension recruited from ED and community-based settings.

OBJECTIVE

We sought to determine the effect of MI-BP on BP as well as secondary outcomes of physical activity, sodium intake, medication adherence, and BP control compared to enhanced usual care control at 1-year follow-up.

METHODS

We conducted a 1-year, 2-group randomized controlled trial of the MI-BP intervention compared to an enhanced usual care control group where participants aged 25 to 70 years received a BP cuff and hypertension-related educational materials. Participants were recruited from EDs and other community-based settings in Detroit, Michigan, where they were screened for initial eligibility and enrolled. Baseline data collection and randomization occurred approximately 2 and 4 weeks after enrollment to ensure that participants had uncontrolled hypertension and were willing to take part. Data collection visits occurred at 13, 26, 39, and 52 weeks. Outcomes of interest included BP (primary outcome) and physical activity, sodium intake, medication adherence, and BP control (secondary outcomes).

RESULTS

We obtained consent from and enrolled 869 participants in this study yet ultimately randomized 162 (18.6%) participants. At 1 year, compared to the baseline, both groups showed significant decreases in systolic BP (MI-BP group: 22.5 mm Hg decrease in average systolic BP and P<.001; control group: 24.1 mm Hg decrease and P<.001) adjusted for age and sex, with no significant differences between the groups (time-by-arm interaction: P=.99). Similar patterns where improvements were noted in both groups yet no differences were found between the groups were observed for diastolic BP, physical activity, sodium intake, medication adherence, and BP control. Large dropout rates were observed in both groups (approximately 60%).

CONCLUSIONS

Overall, participants randomized to both the enhanced usual care control and MI-BP conditions experienced significant improvements in BP and other outcomes; however, differences between groups were not detected, speaking to the general benefit of proactive outreach and engagement focused on cardiometabolic risk reduction in urban-dwelling, low-socioeconomic-status Black populations. High dropout rates were found and are likely to be expected when working with similar populations. Future work is needed to better understand engagement with mobile health interventions, particularly in this population.

The effect of self-management techniques on relevant outcomes in chronic low back pain: A systematic review and meta-analysis

BACKGROUND AND OBJECTIVE

Among many treatment approaches for chronic low back pain (CLBP), self-management techniques are becoming increasingly important. The aim of this paper was to (a) provide an overview of existing digital self-help interventions for CLBP and (b) examine the effect of these interventions in reducing pain intensity, pain catastrophizing and pain disability.

DATABASES AND DATA TREATMENT

Following the PRISMA guideline, a systematic literature search was conducted in the MEDLINE, EMBASE, PsychInfo, CINAHL and Cochrane databases. We included randomized controlled trials from the last 10 years that examined the impact of digital self-management interventions on at least one of the three outcomes in adult patients with CLBP (duration ≥3 months). The meta-analysis was based on random-effects models. Standardized tools were used to assess the risk of bias (RoB) for each study and the quality of evidence for each outcome.

RESULTS

We included 12 studies (n = 1545). A small but robust and statistically significant pooled effect was found on pain intensity (g = 0.24; 95% CI [0.09, 0.40], k = 12) and pain disability (g = 0.43; 95% CI [0.27, 0.59], k = 11). The effect on pain catastrophizing was not significant (g = 0.38; 95% CI [-0.31, 1.06], k = 4). The overall effect size including all three outcomes was g = 0.33 (95% CI [0.21, 0.44], k = 27). The RoB of the included studies was mixed. The quality of evidence was moderate or high.

CONCLUSION

In summary, we were able to substantiate recent evidence that digital self-management interventions are effective in the treatment of CLBP. Given the heterogeneity of interventions, further research should aim to investigate which patients benefit most from which approach.

SIGNIFICANCE

This meta-analysis examines the effect of digital self-management techniques in patients with CLBP. The results add to the evidence that digital interventions can help patients reduce their pain intensity and disability. A minority of studies point towards the possibility that digital interventions can reduce pain catastrophizing. Future research should further explore which patients benefit most from these kinds of interventions.

Software-based interventions for low back pain management: A systematic review and meta-analysis

INTRODUCTION

Using software for self-management interventions can improve health outcomes for individuals with low back pain, but there is a dearth of research to confirm its effectiveness. Additionally, no known research has evaluated the effective elements of software-based interventions for low back pain self-management components. This study aimed to synthesize the effectiveness of software-based interventions to promote self-management health outcomes among individuals with low back pain.

DESIGN

A systematic review and meta-analysis was conducted.

METHODS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement, relevant studies up to July 2022 were searched via four electronic databases: PubMed, Embase, Cumulative Index to Nursing and Allied Health Literature, and Web of Science.

RESULTS

4908 adults with low back pain who participated in 23 studies were included. Software-based interventions were effective in reducing fear avoidance (mean difference [MD] = -0.95, 95% CI: -1.45 to -0.44), pain catastrophizing (MD = -1.31, 95% CI: -1.84 to -0.78), disability (MD = -8.21, 95% CI: -13.02 to -3.39), and pain intensity (MD = -0.86, 95% CI: -1.17 to -0.55). Specifically, interventions that included an exercise component were more effective in reducing pain and disability. Additionally, cognitive behavioral therapy (CBT) intervention significantly reduced fear avoidance and pain catastrophizing but had no noticeable impact on disability and pain compared to standard treatment. The certainty of the evidence in this review varied from very low to high across outcomes. The heterogeneity of the study results was significant, suggesting that future studies in this area could optimize the design, time points, measures, and outcomes to strengthen the evidence.

CONCLUSIONS

Low back pain self-management interventions delivered through software-based programs effectively reduce pain intensity, disability, fear avoidance, and pain catastrophizing.

CLINICAL RELEVANCE

Low back pain is among the most common reasons for seeking healthcare visits. Combining exercise and counseling through soft-based programs may effectively address this issue and its associated suffering and disability.

Effects of Lifestyle Interventions on the Improvement of Chronic Non-Specific Low Back Pain: A Systematic Review and Network Meta-Analysis

Chronic non-specific low back pain (CNSLBP) is a highly prevalent musculoskeletal condition that has a great socioeconomic impact on health systems. Instead of focusing on mechanical causes and direct workload in the development of CNSLBP, genetics, psychosocial environment, lifestyle and quality of life are coming to the forefront in its approach. The main objective was to analyze whether interventions aimed at modifying lifestyle can be effective in improving pain intensity and functional disability in CNSLBP. A search in PubMed, Web of Science, Scopus and SportDiscus databases was performed. Both a univariate and a multivariate network meta-analysis were applied with the difference pre/post-treatment. A total of 20 studies were included for qualitative analysis, of which 16 were randomized clinical trials with a moderate-high methodological quality and were part of the quantitative analysis. The interventions that had the greatest effect in reducing pain intensity were cognitive therapy combined with functional exercise programs, lumbar stabilization exercise and resistance exercise; meanwhile, for functional disability, they were functional exercise programs, aerobic exercise and standard care. In conclusion, a multimodal intervention aimed at changing one's lifestyle that encompasses cognitive, behavioral, and physical aspects seems to be highly effective in improving pain intensity and functional disability caused by CNSLBP; however, it is not yet known if these improvements are maintained in the long term.

The Impact of a Physiotherapy Tele-Rehabilitation Program on the Quality of Care for Children with Juvenile Idiopathic Arthritis

Objectives

To investigate the applicability and impact of a physiotherapy tele-rehabilitation program (TRP) on children with Juvenile Idiopathic Arthritis (JIA) and their families.

Methods

Thirty JIA patients, applying an individualized home-exercise program (HEP), were randomly divided in the tele-rehabilitation (TRG, n=15) and control group (CG, n=15). Each TRG patient participated in a 30-minute tele-session, under a paediatric physiotherapist's supervision, twice a week, for 12 weeks. Before and after the TRP (T1 and T2, respectively), all participants and a parent/guardian completed the Juvenile Arthritis Multidimensional Assessment Report (JAMAR) questionnaire and a questionnaire regarding the HEP implementation and compliance. Residual disease was estimated at T1 and T2. At T2, TRG patients/parents completed a questionnaire evaluating the TRP. One month after T2, a reassessment of compliance with the HEP was performed.

Results

The patients' median age was 12.8 (8-16) years. At T2, the TRG patients performed the HEP significantly more frequently (p=0.023), for a longer time (p=0.034) and with less urging (p=0.004), compared to T1. Moreover, they exhibited significantly increased compliance with HEP (p=0.001), better functionality (p=0.008), better quality of life (p=0.007) and less pain (p=0.017). The CG patients showed no significant changes. Residual disease improved in both groups (TRG:p=0.002, CG:p=0.018), but more in the TRG (p=0.045). TRP's applicability and total benefit were rated as excellent by patients/parents. Finally, one month after T2, compliance with the HEP was still greater than at T1(p=0.001).

Conclusion

An interactive physiotherapy TRP can be implemented effectively for JIA patients, providing an additional tool for their rehabilitation.

Effectiveness of remote physiotherapeutic e-Health interventions on pain in patients with musculoskeletal disorders: a systematic review

PURPOSE

To systematically review the literature on effectiveness of remote physiotherapeutic e-Health interventions on pain in patients with musculoskeletal disorders.

MATERIALS AND METHODS

Using online data sources PubMed, Embase, and Cochrane in adults with musculoskeletal disorders with a pain-related complaint. Remote physiotherapeutic e-Health interventions were analysed. Control interventions were not specified. Outcomes on effect of remote e-Health interventions in terms of pain intensity.

RESULTS

From 11,811 studies identified, 27 studies were included. There is limited evidence for the effectiveness for remote e-Health for patients with back pain based on five articles. Twelve articles studied chronic pain and the effectiveness was dependent on the control group and involvement of healthcare providers. In patients with osteoarthritis (five articles), total knee surgery (two articles), and knee pain (three articles) no significant effects were found for remote e-Health compared to control groups.

CONCLUSIONS

There is limited evidence for the effectiveness of remote physiotherapeutic e-Health interventions to decrease pain intensity in patients with back pain. There is some evidence for effectiveness of remote e-Health in patients with chronic pain. For patients with osteoarthritis, after total knee surgery and knee pain, there appears to be no effect of e-Health when solely looking at reduction of pain. Implications for rehabilitationThis review shows that e-Health can be an effective way of reducing pain in some populations.Remote physiotherapeutic e-Health interventions may decrease pain intensity in patients with back pain.Autonomous e-Health is more effective than no treatment in patients with chronic pain.There is no effect of e-Health in reduction of pain for patients with osteoarthritis, after total knee surgery and knee pain.

The effectiveness of different aerobic exercises to improve pain intensity and disability in chronic low back pain patients: a systematic review

Background: Physical activity, including aerobic exercise, is highly recommended for chronic low back pain (CLBP) patients to improve pain intensity and functional disability. Objectives: To assess the effectiveness of different aerobic exercises to reduce pain intensity and functional disability in patients with CLBP. Methods: A computer-aided search was performed to find Randomised Controlled Trials (RCTs) that evaluated the effectiveness of different aerobic exercises in CLBP. Articles published between January 2007 to December 2020 were included in the review. Quality assessment using the PEDro scale, extraction of relevant information, and evaluation of outcomes were done by two reviewers independently. Results: A total of 17 studies were included that involved 1146 participants. Outcomes suggested that aerobic exercise combined with other interventions was more effective than aerobic exercise alone. Aerobic exercise with higher frequency (≥ 5 days/week) and longer duration (≥ 12 weeks) were effective to gain clinically significant (≥ 30%) improvements. Environment and using pedometer did not seem to influence the outcomes. Conclusions: Pain intensity and functional disability in CLBP patients can be minimized by prescribing aerobic exercise. However, to get better improvements, aerobic exercise should be done in combination with other interventions and at optimum frequency and duration. Further studies should emphasize examining the optimal doses and duration of different aerobic exercises.

Exercise Increases Pain Self-efficacy in Adults With Nonspecific Chronic Low Back Pain: A Systematic Review and Meta-analysis

OBJECTIVE: To determine the effect of exercise on pain self-efficacy in adults with nonspecific chronic low back pain (NSCLBP). DESIGN: Intervention systematic review with meta-analysis LITERATURE SEARCH: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Embase, PsycINFO, and CINAHL databases from October 20, 2018, to March 23, 2022. SELECTION CRITERIA: We included randomized controlled trials that compared the effect of exercise on pain self-efficacy to control, in adults with NSCLBP. DATA SYNTHESIS: We conducted a meta-analysis using a random-effects model. We evaluated the risk of bias using the Cochrane risk-of-bias tool (RoB 2) and judged the certainty of evidence using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) framework. RESULTS: Seventeen trials were included, of which eight (n = 1121 participants; 60.6% female; mean age: 49.6 years) were included in the meta-analysis. Exercise increased pain self-efficacy by 3.02 points (95% confidence interval: 1.72, 4.32) on the 60-point Pain Self-Efficacy Questionnaire. The certainty of evidence was moderate; all trials were at high risk of bias. CONCLUSION: There was moderate-certainty evidence that exercise increased pain self-efficacy in adults with NSCLBP. Future research should investigate if this effect is meaningful, whether it increases with more targeted treatments to enhance pain self-efficacy, and the effects on outcomes for adults with NSCLBP.

to analyze the effectiveness of digital self-care in the management of pain and functional disability among people with spine musculoskeletal disorders. a systematic literature review, developed with the PRISMA checklist, of randomized clinical trials of people with spine musculoskeletal disorders and digital interventions accessed by means of computers, smartphones or other portable devices. Databases researched: National Library of Medicine, Excerpta Médica dataBASE, SciVerse Scopus, Literatura Latino-Americana e do Caribe em Ciências da Saúde, Science Citation Indexes, Cumulative Index to Nursing and Allied Health Literature and Physiotherapy Evidence Database. The descriptive synthesis of the results and by means of meta-analyses (fixed-effects model) was performed with the Review Manager software. The methodological quality was evaluated with the Physiotherapy Evidence Database scale. a total of 25 trials were selected (5,142 participants), which showed statistically significant improvements (p <0.05) in 54% (12/22) in the pain levels and 47% (10/21) in functional disability in the Intervention Group. The meta-analyses showed moderate effects on pain intensity and small effects on functional disability. There was a predominance of medium quality studies. the digital care interventions showed a beneficial result in pain intensity and in functional disability, mainly for chronic low back pain. Digital care emerges as promising to support self-management of the spine musculoskeletal conditions. PROSPERO registry number CRD42021282102.

In non-specific low back pain, is an exercise program carried out through telerehabilitation as effective as one carried out in a physiotherapy center? A controlled randomized trial

BACKGROUND

s:The effectiveness of telerehabilitation (TLRH) in patients with non-specific low back pain (NLBP) remains unknown. No study till date has investigated the efficacy of a mobile-based TLRH in patients with NLBP.

OBJECTIVES

To investigate if a TLRH program is as effective as a clinical exercise programme in improving disability, pain intensity, pain catastrophizing, and hip pain and strength in patients with NLBP.

DESIGN

Single-blind, two-armed, randomized controlled study.

METHOD

A total of 71 individuals with NLBP were randomly allocated to either the TLRH home group (TLRH) or clinic group (CG). The TLRH followed exercise videos and read information on pain neurophysiology. The CG performed the same exercises and received on-site pain education. Both groups performed the exercises twice weekly for 8 weeks. Disability, pain intensity, pain catastrophizing, and hip pain and strength were assessed at baseline, at post-treatment, and at three months.

RESULTS

Statistically significant differences for time-by-group interaction were detected in the strength of left hip flexors (supine [F = 8.356; p = .005]; sitting [F = 9.828; p = .003]), right hip extensors with extended knee [F = 7.461; p = .008], left hip extensors (extended knee [F = 13.175; p = .001]; flexed knee [F = 13.505; p < .001]), pain during flexion of the right [F = 5.133; p = .027] and left [F = 4.731; p = .033] hips in the supine position, disability [F = 4.557; p = .014], and pain catastrophizing [F = 14.132; p < .001].

CONCLUSION

A TLRH mobile-based is as effective as clinical treatment in improving disability, pain catastrophizing, and pain and strength of the hip structures in patients with NLBP.

Measuring Engagement with Mental Health and Behavior Change Interventions: an Integrative Review of Methods and Instruments

BACKGROUND

Engagement is a complex construct consisting of behavioral, cognitive, and affective dimensions, making engagement a difficult construct to measure. This integrative review aims to (1) present a multidisciplinary overview of measurement methods that are currently used to measure engagement with adult mental health and behavior change interventions, delivered in-person, blended, or digitally, and (2) provide a set of recommendations and considerations for researchers wishing to study engagement.

METHODS

We used an integrative approach and identified original studies and reviews on engagement with mental health or behavior change interventions that were delivered in-person, digitally, or blended.

RESULTS

Forty articles were analyzed in this review. Common methods to assess engagement were through objective usage data, questionnaire-based data, and qualitative data, with objective usage data being used most frequently. Based on the synthesis of engagement measures, we advise researchers to (1) predefine the operationalization of engagement for their specific research context, (2) measure behavioral, cognitive, and affective dimensions of engagement in all cases, and (3) measure engagement over time.

CONCLUSIONS

Current literature shows a bias towards behavioral measures of engagement in research, as most studies measured engagement exclusively through objective usage data, without including cognitive and affective measures of engagement. We hope that our recommendations will help to reduce this bias and to steer engagement research towards an integrated approach.

The effect of exercise on the quality of life in an academic environment

Regular physical activity has a direct association with an improvement in perceived health-related quality of life (HRQL). Because many Saudis are reportedly inactive, Imam Abdulrahman bin Faisal University established a walking challenge for all university employees to encourage a better lifestyle and to promote health awareness. This study aims to measure the differences in the participants' HRQL scores before and after the challenge. A before and after study was conducted using HRQL survey that was sent to all university employees before the implementation of a pedometer-based walking challenge at the study setting, and after the challenge ended. A randomized snowball sample method was used to recruit participants. The differences in the overall HRQL before and after the challenge were calculated. A RAND SF20-items scale was used to measure the participants' HRQL scores, along with other information such as academic qualifications. Most of the participants were between 31 and 50 years old, and 40% were males. There was a statistically significant difference in the overall HRQL scores before and after the walking challenge intervention. The HRQL score increased from 50.77 before the challenge to 55.53 after the challenge (paired t-test = - 4.322, P < 0.0001). An odds ratio (OR) showed that the odds of having higher HRQL scores increased by 88% after the walking challenge, compared to before the walking challenge (OR = 1.88; 95% CI = 1.269-2.809; P = 0.002). Physical activity by itself can improve a community's overall health and quality of life. Similar interventions are encouraged in all public and private sectors in the country.

A systematic review and meta-analysis of digital application use in clinical research in pain medicine

IMPORTANCE

Pain is a silent global epidemic impacting approximately a third of the population. Pharmacological and surgical interventions are primary modes of treatment. Cognitive/behavioural management approaches and interventional pain management strategies are approaches that have been used to assist with the management of chronic pain. Accurate data collection and reporting treatment outcomes are vital to addressing the challenges faced. In light of this, we conducted a systematic evaluation of the current digital application landscape within chronic pain medicine.

OBJECTIVE

The primary objective was to consider the prevalence of digital application usage for chronic pain management. These digital applications included mobile apps, web apps, and chatbots.

DATA SOURCES

We conducted searches on PubMed and ScienceDirect for studies that were published between 1st January 1990 and 1st January 2021.

STUDY SELECTION

Our review included studies that involved the use of digital applications for chronic pain conditions. There were no restrictions on the country in which the study was conducted. Only studies that were peer-reviewed and published in English were included. Four reviewers had assessed the eligibility of each study against the inclusion/exclusion criteria. Out of the 84 studies that were initially identified, 38 were included in the systematic review.

DATA EXTRACTION AND SYNTHESIS

The AMSTAR guidelines were used to assess data quality. This assessment was carried out by 3 reviewers. The data were pooled using a random-effects model.

MAIN OUTCOMES AND MEASURES

Before data collection began, the primary outcome was to report on the standard mean difference of digital application usage for chronic pain conditions. We also recorded the type of digital application studied (e.g., mobile application, web application) and, where the data was available, the standard mean difference of pain intensity, pain inferences, depression, anxiety, and fatigue.

RESULTS

38 studies were included in the systematic review and 22 studies were included in the meta-analysis. The digital interventions were categorised to web and mobile applications and chatbots, with pooled standard mean difference of 0.22 (95% CI: -0.16, 0.60), 0.30 (95% CI: 0.00, 0.60) and -0.02 (95% CI: -0.47, 0.42) respectively. Pooled standard mean differences for symptomatologies of pain intensity, depression, and anxiety symptoms were 0.25 (95% CI: 0.03, 0.46), 0.30 (95% CI: 0.17, 0.43) and 0.37 (95% CI: 0.05, 0.69), respectively. A sub-group analysis was conducted on pain intensity due to the heterogeneity of the results (I ² = 82.86%; p = 0.02). After stratifying by country, we found that digital applications were more likely to be effective in some countries (e.g., United States, China) than others (e.g., Ireland, Norway).

CONCLUSIONS AND RELEVANCE

The use of digital applications in improving pain-related symptoms shows promise, but further clinical studies would be needed to develop more robust applications.

Digital Health Interventions for Musculoskeletal Pain Conditions: Systematic Review and Meta-analysis of Randomized Controlled Trials

Background

Digital health solutions can provide populations with musculoskeletal pain with high-reach, low-cost, easily accessible, and scalable patient education and self-management interventions that meet the time and resource restrictions.

Objective

The main objective of this study was to determine the effectiveness of digital health interventions for people with musculoskeletal pain conditions (ie, low back pain, neck pain, shoulder pain, knee pain, elbow pain, ankle pain, and whiplash).

Methods

A systematic review and meta-analysis was conducted. We searched PubMed and Cochrane Central Register of Controlled Trials (from 1974 to August 2021) and selected randomized controlled trials of digital health interventions in the target population of patients with musculoskeletal pain with a minimum follow-up of 1 month. A total of 2 researchers independently screened and extracted the data.

Results

A total of 56 eligible studies were included covering 9359 participants, with a mean follow-up of 25 (SD 15.48) weeks. In moderate-quality evidence, digital health interventions had a small effect on pain (standardized mean difference [SMD] 0.19, 95% CI 0.06-0.32), disability (SMD 0.14, 95% CI 0.03-0.25), quality of life (SMD 0.22, 95% CI 0.07-0.36), emotional functioning (SMD 0.24, 95% CI 0.12-0.35), and self-management (SMD 0.14, 95% CI 0.05-0.24).

Conclusions

Moderate-quality evidence supports the conclusion that digital health interventions are effective in reducing pain and improving functioning and self-management of musculoskeletal pain conditions. Low-quality evidence indicates that digital health interventions can improve the quality of life and global treatment. Little research has been conducted on the influence of digital health on expenses, knowledge, overall improvement, range of motion, muscle strength, and implementation fidelity.

The Role of Exercise in Treating Low Back Pain

ABSTRACT

The purpose of this review is to highlight the role of exercise in preventing and managing acute and chronic axial low back pain (LBP). LBP is one of the leading contributors to years lived with disability as well as health care expenditures in the United States. With an expected increase in prevalence due to an aging population, sports medicine providers have a unique opportunity to provide effective treatment strategies incorporating exercise advice and prescription. Although the majority of individuals with acute LBP will have their symptoms resolve spontaneously, almost 40% will have recurrence or develop chronic LBP within 1 year. No single exercise method has been shown to be more effective than another. The evidence for walking programs, aerobic exercise, yoga, Pilates, and tai chi for LBP is discussed. Our review summarizes the beneficial role of a personalized exercise program and related counseling strategies in the prevention and management of LBP.

Relationship between the number of steps taken during lockdown caused by the COVID-19 pandemic and low back pain

Introduction: In 2020, the whole world was overwhelmed by the SARS-CoV-2 coronavirus threat. In order to prevent the spread of the virus, national governments introduced restrictions of movement in public space, closing schools, universities, many companies switched to remote working. In addition to the obvious benefits of the above changes, numerous side effects can be observed. One of them is pain in the locomotive organs caused by the sedentary lifestyle. Objective: The main objective of the study was to assess the relationship between physical activity during quarantine, caused by the COVID-19 pandemic, and the occurrence of spinal pain. Material and methods: The study was attended by 55 people (29 women and 26 men) who attended physiotherapeutic consultations due to low back pain. For comparison purposes, they were divided into two groups: Group 1 (n=24) includes active persons, Group 2 (n=31) includes inactive persons. The survey was conducted in June 2020. The study used the reading of pedometers from mobile phones and the Rolland-Morris Questionnaire, Laitinen’s Pain Scale and author’s own questionnaire. The respondents were asked to share the pedometer results from given weeks before, during and after restriction causes by the COVID-19. Results: Physically active persons (those performing health training) performed more steps before introducing restrictions (p<0.001). After the introduction of restrictions, all-day activity decreased significantly in both groups. The evaluation of pain characteristics revealed significant differences (between groups) in two categories – pain intensity and physical activity limitation. Group 2 individuals also reported greater functional limitations. Conclusion: In physically inactive people, the intensity of low back pain was much higher. This proves the relationship between activity levels and pain.

The Effectiveness of Interventions and Intervention Components for Increasing Physical Activity and Reducing Sedentary Behaviour in People With Persistent Musculoskeletal Pain: A Systematic Review and Meta-Analysis

This systematic review and meta-analysis investigated the effectiveness of physical activity (PA) and sedentary behavior (SB) interventions on PA and SB levels in people with persistent musculoskeletal pain. We explored the effectiveness of behavior change techniques (BCTs), the use of behavior change theory and non-PA/SB outcomes. Randomized controlled trials of PA or SB interventions for people with persistent musculoskeletal pain were eligible. Twenty-three studies were included. Quality of evidence was assessed using the GRADE approach. Meta-analysis demonstrated a small effect for PA post-intervention (Hedge's g = .321, CI .136-.507, P = .001, very low-quality evidence). There was no effect for longer-term follow-up PA (low quality evidence) or SB outcomes (very low-quality evidence). There was a small effect for studies with low risk-of-bias at longer-term follow-up PA. Self-report PA outcomes, PA and education interventions, non-self-selected PA, a combination of supervised and unsupervised PA and a combination of individual and group-based interventions had larger effects. Heterogeneity was moderate to considerable. Risk-of-bias, assessed using Cochrane risk-of-bias tool (version two), was generally low. Five promising BCTs were identified: "adding objects to the environment," "goal setting (outcome)," "action planning," "monitoring outcome(s) of behaviour by others without feedback" and "feedback on outcome(s) of behaviour." In conclusion, there is evidence for a modest benefit for PA interventions immediately post-intervention, however the quality of evidence is very low. There was no evidence for longer-term follow-up PA or SB. Higher quality studies of PA and SB interventions that use objective measures are needed. PROSPERO registration: CRD42020180260. PERSPECTIVE: This review investigated the effects of physical activity and sedentary behavior interventions on physical activity and sedentary behavior levels in people with persistent musculoskeletal pain. Current evidence shows a modest benefit for interventions on physical activity post-intervention but not at longer-term follow-up or on sedentary behavior at any time-point, however quality of evidence is low to very low.

Psychological interventions for chronic, non-specific low back pain: systematic review with network meta-analysis

OBJECTIVE

To determine the comparative effectiveness and safety of psychological interventions for chronic low back pain.

DESIGN

Systematic review with network meta-analysis.

DATA SOURCES

Medline, Embase, PsycINFO, Cochrane Central Register of Controlled Trials, Web of Science, SCOPUS, and CINAHL from database inception to 31 January 2021.

ELIGIBILITY CRITERIA FOR STUDY SELECTION

Randomised controlled trials comparing psychological interventions with any comparison intervention in adults with chronic, non-specific low back pain. Two reviewers independently screened studies, extracted data, and assessed risk of bias and confidence in the evidence. Primary outcomes were physical function and pain intensity. A random effects network meta-analysis using a frequentist approach was performed at post-intervention (from the end of treatment to <2 months post-intervention); and at short term (≥2 to <6 months post-intervention), mid-term (≥6 to <12 months post-intervention), and long term follow-up (≥12 months post-intervention). Physiotherapy care was the reference comparison intervention. The design-by-treatment interaction model was used to assess global inconsistency and the Bucher method was used to assess local inconsistency.

RESULTS

97 randomised controlled trials involving 13 136 participants and 17 treatment nodes were included. Inconsistency was detected at short term and mid-term follow-up for physical function, and short term follow-up for pain intensity, and were resolved through sensitivity analyses. For physical function, cognitive behavioural therapy (standardised mean difference 1.01, 95% confidence interval 0.58 to 1.44), and pain education (0.62, 0.08 to 1.17), delivered with physiotherapy care, resulted in clinically important improvements at post-intervention (moderate quality evidence). The most sustainable effects of treatment for improving physical function were reported with pain education delivered with physiotherapy care, at least until mid-term follow-up (0.63, 0.25 to 1.00; low quality evidence). No studies investigated the long term effectiveness of pain education delivered with physiotherapy care. For pain intensity, behavioural therapy (1.08, 0.22 to 1.94), cognitive behavioural therapy (0.92, 0.43 to 1.42), and pain education (0.91, 0.37 to 1.45), delivered with physiotherapy care, resulted in clinically important effects at post-intervention (low to moderate quality evidence). Only behavioural therapy delivered with physiotherapy care maintained clinically important effects on reducing pain intensity until mid-term follow-up (1.01, 0.41 to 1.60; high quality evidence).

CONCLUSIONS

For people with chronic, non-specific low back pain, psychological interventions are most effective when delivered in conjunction with physiotherapy care (mainly structured exercise). Pain education programmes (low to moderate quality evidence) and behavioural therapy (low to high quality evidence) result in the most sustainable effects of treatment; however, uncertainty remains as to their long term effectiveness. Although inconsistency was detected, potential sources were identified and resolved.

Implementation of Online Behavior Modification Techniques in the Management of Chronic Musculoskeletal Pain: A Systematic Review and Meta-Analysis

Purpose: The main aim of this systematic review and meta-analysis (MA) was to assess the effectiveness of online behavior modification techniques (e-BMT) in the management of chronic musculoskeletal pain. Methods: We conducted a search of Medline (PubMed), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, APA PsychInfo, and Psychological and Behavioral Collections, from inception to the 30 August 2021. The main outcome measures were pain intensity, pain interference, kinesiophobia, pain catastrophizing and self-efficacy. The statistical analysis was conducted using RStudio software. To compare the outcomes reported by the studies, we calculated the standardized mean difference (SMD) over time and the corresponding 95% confidence interval (CI) for the continuous variables. Results: Regarding pain intensity (vs. usual care/waiting list), we found a statistically significant trivial effect size in favor of e-BMT (n = 5337; SMD = −0.17; 95% CI −0.26, −0.09). With regard to pain intensity (vs. in-person BMT) we found a statistically significant small effect size in favor of in-person BMT (n = 486; SMD = 0.21; 95%CI 0.15, 0.27). With respect to pain interference (vs. usual care/waiting list) a statistically significant small effect size of e-BMT was found (n = 1642; SMD = −0.24; 95%CI −0.44, −0.05). Finally, the same results were found in kinesiophobia, catastrophizing, and self-efficacy (vs. usual care/waiting list) where we found a statistically significant small effect size in favor of e-BMT. Conclusions: e-BMT seems to be an effective option for the management of patients with musculoskeletal conditions although it does not appear superior to in-person BMT in terms of improving pain intensity.

Technical Feasibility of Supervision of Stretching Exercises by a Humanoid Robot Coach for Chronic Low Back Pain: The R-COOL Randomized Trial

Adherence to exercise programs for chronic low back pain (CLBP) is a major issue. The R-COOL feasibility study evaluated humanoid robot supervision of exercise for CLBP. Aims are as follows: (1) compare stretching sessions between the robot and a physiotherapist (control), (2) compare clinical outcomes between groups, and (3) evaluate participant perceptions of usability and satisfaction and therapist acceptability of the robot system. Prospective, randomized, controlled, single-blind, 2-centre study comparing a 3-week (3 hours/day, 5 days/week) physical activity program. Stretching sessions (30 minutes/day) were supervised by a physiotherapist (control) or the robot. Primary outcome: daily physical activity time (adherence). Secondary outcomes: lumbar pain, disability and fear and beliefs, participant perception of usability (system usability scale) and satisfaction, and physiotherapist acceptability (technology acceptance model). Clinical outcomes were compared between groups with a Student t-test and perceptions with a Wilcoxon test. Data from 27 participants were analysed (n = 15 control and n = 12 robot group). Daily physical activity time did not differ between groups, but adherence declined (number of movements performed with the robot decreased from 82% in the first week to 72% in the second and 47% in the third). None of the clinical outcomes differed between groups. The median system usability scale score was lower in the robot group: 58 (IQR 11.8) points vs. 87 (IQR 9.4) in the control group at 3 weeks (p < 0.001). Median physiotherapist rating of the technology acceptance model was <3 points, suggesting a negative opinion of the robot. In conclusion, adherence to robot exercise reduced over time; however, lumbar pain, disability, or fear and beliefs did not differ between groups. The results of the participant questionnaires showed that they were willing to use such a system, although several technical issues suggested the KERAAL system could be improved to provide fully autonomous supervision of physical activity sessions.

A vision for the future of wearable sensors in spine care and its challenges: narrative review

OBJECTIVE

This review aimed to: (I) provide a brief overview of some topical areas of current literature regarding applications of wearable sensors in the management of low back pain (LBP); (II) present a vision for a future comprehensive system that integrates wearable sensors to measure multiple parameters in the real world that contributes data to guide treatment selection (aided by artificial intelligence), uses wearables to aid treatment support, adherence and outcome monitoring, and interrogates the response of the individual patient to the prescribed treatment to guide future decision support for other individuals who present with LBP; and (III) consider the challenges that will need to be overcome to make such a system a reality.

BACKGROUND

Advances in wearable sensor technologies are opening new opportunities for the assessment and management of spinal conditions. Although evidence of improvements in outcomes for individuals with LBP from the use of sensors is limited, there is enormous future potential.

METHODS

Narrative review and literature synthesis.

CONCLUSIONS

Substantial research is underway by groups internationally to develop and test elements of this system, to design innovative new sensors that enable recording of new data in new ways, and to fuse data from multiple sources to provide rich information about an individual's experience of LBP. Together this system, incorporating data from wearable sensors has potential to personalise care in ways that were hitherto thought impossible. The potential is high but will require concerted effort to develop and ultimately will need to be feasible and more effective than existing management.

Walking, Cycling, and Swimming for Nonspecific Low Back Pain: A Systematic Review With Meta-analysis

OBJECTIVE

To investigate the effectiveness of walking/running, cycling, or swimming for treating or preventing nonspecific low back pain (LBP).

DESIGN

Intervention systematic review.

LITERATURE SEARCH

Five databases were searched to April 2021.

STUDY SELECTION CRITERIA

Randomized controlled trials evaluating walking/running, cycling, or swimming to treat or prevent LBP were included.

DATA SYNTHESIS

We calculated standardized mean differences (SMDs) and 95% confidence intervals (CIs). Certainty of evidence was evaluated with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

RESULTS

No trials assessed LBP prevention or addressed acute LBP. Nineteen trials (2362 participants) assessed treatment of chronic/recurrent LBP. Low-certainty evidence suggests that walking/running was less effective than alternate interventions in reducing pain in the short term (8 trials; SMD, 0.81; 95% CI: 0.28, 1.34) and medium term (5 trials; SMD, 0.80; 95% CI: 0.10, 1.49). High-certainty evidence suggests that walking/running was less effective than alternate interventions at reducing disability in the short term (8 trials; SMD, 0.22; 95% CI: 0.06, 0.38) and medium term (4 trials; SMD, 0.28; 95% CI: 0.05, 0.51). There was high-certainty evidence of a small effect in favor of walking/running compared to minimal/no intervention for reducing pain in the short term (10 trials; SMD, -0.23; 95% CI: -0.35, -0.10) and medium term (6 trials; SMD, -0.26; 95% CI: -0.40, -0.13) and disability in the short term (7 trials; SMD, -0.19; 95% CI: -0.33, -0.06). Scarcity of trials meant few conclusions could be drawn regarding cycling and swimming.

CONCLUSION

Although less effective than alternate interventions, walking/running was slightly more effective than minimal/no intervention for treating chronic/recurrent LBP. J Orthop Sports Phys Ther 2022;52(2):85-99. Epub 16 Nov 2021. doi:10.2519/jospt.2022.10612.

Telehealth Treatment for Non-Specific Low Back Pain: A Review of the Current State in Mobile Health

INTRODUCTION

Non-specific low back pain (LBP) is an idiopathic musculoskeletal condition that affects 4 out of 5 individuals in their lifetime and is the leading cause of job-related disability in the United States (US). The interest in interactive and dynamic telehealth treatments for LBP continues to grow, and it is important for the medical community to remain up-to-date on the state of the science.

LITERATURE SURVEY

Relevant studies published from March 2016 until March 2021 were identified through a systematic search of EMBASE, MedLine and Web of Science. The search strategy combined the concepts of back pain, telehealth and mobile applications.

METHODOLOGY

Titles and abstracts were screened to select full text randomized controlled trials or protocols and methodological quality and risk of bias was assessed using the Cochrane risk-of-bias tool. Data were synthesized narratively.

SYNTHESIS

We included seven concluded randomized controlled trials and two study protocols reporting mobile health (mHealth) solutions for LBP. Six of the seven concluded trials found a significant improvement in self-reported numerical pain rating scale compared to the control group. A single trial compared a mHealth solution to physical therapy, with the majority of studies comparing interventions to "usual care." Substantial heterogeneity in reporting of sample characteristics was found, indicating a lack of standardization through the field.

CONCLUSIONS

mHealth solutions may positively impact people with LBP. Larger trials should be encouraged and the field should coalesce around a set of baseline variables for collection and reporting. As many interventions involve patient engagement, future trials should aim to further quantify adherence levels and begin to define telehealth 'doses' associated with better outcomes.

Exercise therapy for chronic low back pain

BACKGROUND

Low back pain has been the leading cause of disability globally for at least the past three decades and results in enormous direct healthcare and lost productivity costs.

OBJECTIVES

The primary objective of this systematic review is to assess the impact of exercise treatment on pain and functional limitations in adults with chronic non-specific low back pain compared to no treatment, usual care, placebo and other conservative treatments.

SEARCH METHODS

We searched CENTRAL (which includes the Cochrane Back and Neck trials register), MEDLINE, Embase, CINAHL, PsycINFO, PEDro, SPORTDiscus, and trials registries (ClinicalTrials.gov and World Health Organization International Clinical Trials Registry Platform), and conducted citation searching of relevant systematic reviews to identify additional studies. The review includes data for trials identified in searches up to 27 April 2018. All eligible trials have been identified through searches to 7 December 2020, but have not yet been extracted; these trials will be integrated in the next update.

SELECTION CRITERIA

We included randomised controlled trials that assessed exercise treatment compared to no treatment, usual care, placebo or other conservative treatment on the outcomes of pain or functional limitations for a population of adult participants with chronic non-specific low back pain of more than 12 weeks' duration.

DATA COLLECTION AND ANALYSIS

Two authors screened and assessed studies independently, with consensus. We extracted outcome data using electronic databases; pain and functional limitations outcomes were re-scaled to 0 to 100 points for meta-analyses where 0 is no pain or functional limitations. We assessed risk of bias using the Cochrane risk of bias (RoB) tool and used GRADE to evaluate the overall certainty of the evidence. When required, we contacted study authors to obtain missing data. To interpret meta-analysis results, we considered a 15-point difference in pain and a 10-point difference in functional limitations outcomes to be clinically important for the primary comparison of exercise versus no treatment, usual care or placebo.

MAIN RESULTS

We included 249 trials of exercise treatment, including studies conducted in Europe (122 studies), Asia (38 studies), North America (33 studies), and the Middle East (24 studies). Sixty-one per cent of studies (151 trials) examined the effectiveness of two or more different types of exercise treatment, and 57% (142 trials) compared exercise treatment to a non-exercise comparison treatment. Study participants had a mean age of 43.7 years and, on average, 59% of study populations were female. Most of the trials were judged to be at risk of bias, including 79% at risk of performance bias due to difficulty blinding exercise treatments. We found moderate-certainty evidence that exercise treatment is more effective for treatment of chronic low back pain compared to no treatment, usual care or placebo comparisons for pain outcomes at earliest follow-up (MD -15.2, 95% CI -18.3 to -12.2), a clinically important difference. Certainty of evidence was downgraded mainly due to heterogeneity. For the same comparison, there was moderate-certainty evidence for functional limitations outcomes (MD -6.8 (95% CI -8.3 to -5.3); this finding did not meet our prespecified threshold for minimal clinically important difference. Certainty of evidence was downgraded mainly due to some evidence of publication bias.  Compared to all other investigated conservative treatments, exercise treatment was found to have improved pain (MD -9.1, 95% CI -12.6 to -5.6) and functional limitations outcomes (MD -4.1, 95% CI -6.0 to -2.2). These effects did not meet our prespecified threshold for clinically important difference. Subgroup analysis of pain outcomes suggested that exercise treatment is probably more effective than education alone (MD -12.2, 95% CI -19.4 to -5.0) or non-exercise physical therapy (MD -10.4, 95% CI -15.2 to -5.6), but with no differences observed for manual therapy (MD 1.0, 95% CI -3.1 to 5.1). In studies that reported adverse effects (86 studies), one or more adverse effects were reported in 37 of 112 exercise groups (33%) and 12 of 42 comparison groups (29%). Twelve included studies reported measuring adverse effects in a systematic way, with a median of 0.14 (IQR 0.01 to 0.57) per participant in the exercise groups (mostly minor harms, e.g. muscle soreness), and 0.12 (IQR 0.02 to 0.32) in comparison groups.

AUTHORS' CONCLUSIONS

We found moderate-certainty evidence that exercise is probably effective for treatment of chronic low back pain compared to no treatment, usual care or placebo for pain. The observed treatment effect for the exercise compared to no treatment, usual care or placebo comparisons is small for functional limitations, not meeting our threshold for minimal clinically important difference. We also found exercise to have improved pain (low-certainty evidence) and functional limitations outcomes (moderate-certainty evidence) compared to other conservative treatments; however, these effects were small and not clinically important when considering all comparisons together. Subgroup analysis suggested that exercise treatment is probably more effective than advice or education alone, or electrotherapy, but with no differences observed for manual therapy treatments.

Wearables-based walking program in addition to usual physiotherapy care for the management of patients with low back pain at medium or high risk of chronicity: A pilot randomized controlled trial

BACKGROUND

Although chronic low back pain (LBP) is a leading cause of disability and accounts for large costs, none of the available conventional treatments are clearly more favourable in treating people at increased risk of chronicity.

OBJECTIVES

To examine the feasibility and initial efficacy of a wearables-based walking intervention in addition to usual physiotherapy care in people with LBP at risk of chronicity.

METHODS

Twenty-six adult participants, diagnosed with non-specific LBP with medium or high risk of chronicity, were recruited from physiotherapy private practices. Participants were randomized into usual physiotherapy care (control, n = 14) and usual physiotherapy care plus a wearables-based walking intervention (experimental, n = 12). The intervention duration was 8 weeks. Feasibility outcomes included recruitment rate, adherence to the intervention, dropout rate, and serious adverse events reporting rate. Other outcomes included disability and pain (primary); and physical activity level, daily walking steps, depression, pain catastrophizing and fear of movement (secondary). The outcomes were assessed at baseline, post-intervention and 26 weeks post-randomization follow-up.

RESULTS

Adherence of experimental participants with the prescribed walking program was moderate. Four participants dropped out during the intervention, and no serious adverse events were reported. Participants in the experimental group showed significant improvement in pain at 26 weeks (β = -0.38; 95% confidence interval (CI) -0.66, -0.10; P = .013), compared with the control group. No between-group differences were found for disability at any time point and pain immediately post-intervention. Experimental participants demonstrated post-intervention improvement in light-intensity (β = 156.71; 95% CI 86.79, 226.64; P < .001), moderate-intensity physical activity (β = 0.46; 95% CI 0.12, 0.80; P = .012), and daily walking steps (β = 7099.13; 95% CI 4522.93, 9675.32; P < .001). Experimental participants demonstrated post-intervention increase in pain catastrophizing (β = 0.52, 95% CI 0.18, 0.86; P = .006). No between-group differences were found for pain catastrophizing at 26 weeks and other secondary outcomes.

CONCLUSION

Usual physiotherapy care plus a wearables-based walking intervention program was safe and moderately feasible, and provided significant reduction in pain at 26 weeks as well as increasing the total volume of light- and moderate-intensity physical activity, and daily walking steps immediately post-intervention.

Using Step Counts to Prescribe Physical Activity: What Is the Optimal Dose?

ABSTRACT

An activity goal of 10,000 steps per day is widely known but was not initially developed based on scientific evidence. The last several years have seen an increase in both the availability of consumer-based step counting devices and research examining the link between daily step counts and various health outcomes. Daily step counts are an intuitive metric of physical activity and are useful for goal-setting and motivating behavioral change. This article reviews the current evidence for daily step counts as related to common health conditions to determine activity goals to prescribe to patients, and also discusses factors to consider when counseling patients on physical activity.

The effectiveness of social media and in-person interventions for low back pain conditions in nursing personnel (SMILE)

AIM

To compare two educational approaches to reduce low back pain in nurses.

DESIGN

A community randomized controlled clinical trial.

METHODS

Data were collected with two interventions and a control arm between August 2018 and January 2019. Participants were recruited from three hospitals. Hospital 1 received an in-person educational programme, Hospital 2 received via the website and Hospital 3 received nothing. Statistical analysis was carried out with a follow-up of 3 and 6 months.

RESULTS

A total of 180 female nurses with low back pain participated in the study. Dimensions of the quality of life improved over 3 and 6 months, pain and disability decreased over 3 months in both intervention groups and over 6 months in the social media group.

CONCLUSION

Two educational approaches can be effective in decreasing pain, disability and improving quality of life. However, the findings suggest that the social media approach was more successful over the long-term and might be a better way to present the programme.

The effect of pedometer-supported walking and telemonitoring after disc hernia surgery on pain and disability levels and quality of life

AIM

The aim of this study was to determine the effect of pedometer-supported walking and telemonitoring after lumbar disc hernia surgery on pain and disability levels and quality of life.

METHODS

This was a randomized controlled trial with two randomly selected groups conducted between March 2018 and January 2019. Sixty-seven participants (33 in the intervention group and 34 in the control group) who had undergone lumbar microdiscectomy were allocated to receive and not to receive walking exercise. Pain and disability levels and quality of life of groups were tested with the McGill Pain Questionnaire, the Oswestry Disability Index and the 36-Item Short Form Survey. Measurements were taken 3 weeks after surgery and following completion of the first, second and third months.

RESULTS

Compared with the control group, pain level at the first and second months and disability level at the second and third months in the intervention group were significantly lower (p < 0.05), and in the third month, subdimension scores of quality of life (the physical role difficulty, energy and vitality, mental health, social functionality and pain) were higher (p < 0.05).

CONCLUSIONS

Walking after herniated disc surgery decreased pain and disability levels and increased the quality of life; nurses can encourage adherence to walking as an effective intervention.

Participatory health through behavioural engagement and disruptive digital technology for postoperative rehabilitation: protocol of the PATHway trial

INTRODUCTION

Postsurgical rehabilitation is critical for optimal recovery in people undergoing orthopaedic surgery. Currently, knee and lumbar spine postsurgical care is not standardised, economically sustainable, nor based on quality evidence, contributing to substantial clinical variation, poor outcomes and increasing healthcare costs. This protocol describes the design of a randomised controlled trial aiming to evaluate the effectiveness and cost-effectiveness of a postsurgical clinical pathway augmented by disruptive technology and compared with standardised rehabilitation alone, in decreasing pain and improving function after total knee replacement (TKR) or lumbar laminectomy (with or without fusion).

METHODS

An assessor-blinded, parallel group, randomised controlled trial will be conducted to recruit 204 consenting participants (102 per arm) of whom 50% are undergoing TKR and 50% lumbar surgery. The intervention group will receive a 6-month technology-enabled rehabilitation package in addition to usual postsurgical care. The package includes (1) an exercise program delivered via the Physitrack app on the iPad, (2) a health-coaching program delivered via video calls and motivational messages, (3) use of physical activity tracker with goal setting and motivational reminders (Fitbit). For those undergoing TKR, the intervention will also include knee joint range of motion self-monitoring via the Goniometer app. The control group will receive usual postsurgical care. Participants will be followed up at 3, 6 and 12 months from the enrolment date. The primary outcome is pain measured with the Numerical Rating Scale at 3 months. Secondary outcomes include pain-related disability, quality of life, computer self-efficacy, physical activity participation and sedentary behaviour. Data analysis will be blinded and by intention-to-treat. A trial-based cost-effectiveness analysis will determine the potential incremental cost per quality-adjusted life-year gained.

ETHICS AND DISSEMINATION

This protocol is approved by the human research ethics committee of the University of Sydney. Dissemination will occur through lay summary, infographics, conferences and journal publications.

Incorporating walking into cognitive behavioral therapy for chronic pain: safety and effectiveness of a personalized walking intervention

We examined the effectiveness and safety of a walking program offered as part of cognitive behavioral therapy for chronic pain (CBT-CP). Participants were randomized to 10 weeks of CBT-CP, delivered either in person or by interactive voice response. Participants reported pedometer-measured step counts daily throughout treatment and received a weekly goal to increase their steps by 10% over the prior week's average. Walking-related adverse events (AEs) were assessed weekly. Participants (n = 125) were primarily male (72%), and white (80%) with longstanding pain (median: 11 years). There was no significant difference between treatment groups in rate of change in daily steps, but there was a significant increase in steps from baseline to treatment termination in the combined study sample (1648 steps (95% CI 1063-2225)). Participants classified as active doubled. AEs were mostly minor and temporary. Treatment was effective and safe whether the program was delivered in-person or remotely.Trial registration number: clinicaltrials.gov identifier: NCT01025752.

The Effectiveness of Strategies to Promote Walking in People With Musculoskeletal Disorders: A Systematic Review With Meta-analysis

OBJECTIVE

To evaluate the effect of walking promotion strategies on physical activity, pain, and function in people with musculoskeletal disorders.

DESIGN

Intervention systematic review with meta-analysis.

LITERATURE SEARCH

We performed the searches in MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and the Physiotherapy Evidence Database (PEDro) from inception to August 2019.

STUDY SELECTION CRITERIA

We included randomized controlled trials evaluating interventions that promote walking in people with musculoskeletal disorders.

DATA SYNTHESIS

We used the PEDro scale for assessing risk of bias and the Grading of Recommendations Assessment, Development and Evaluation approach to evaluate the quality of evidence. We expressed pooled effects for between-group differences as mean differences or standardized mean differences and 95% confidence intervals, or as risk ratios and 95% confidence intervals, using random-effects meta-analyses.

RESULTS

Twelve eligible trials (n = 1456 participants) were identified. There was moderate- to very low-quality evidence of no difference in physical activity levels for walking promotion interventions when compared to minimal interventions, and a significant effect favoring walking promotion when compared with usual care in the short term. There was moderate-quality evidence that walking promotion was modestly effective for reducing pain and improving function compared with minimal intervention and usual care. There was no difference in pain and function for walking promotion compared to supervised exercise. Walking promotion was not associated with different rates of adverse events compared to control conditions.

CONCLUSION

Strategies to promote walking did not increase physical activity in people with musculoskeletal disorders. Walking promotion was associated with small improvements in pain and function compared to minimal intervention and usual care.

Effectiveness of walking versus mind-body therapies in chronic low back pain: A systematic review and meta-analysis of recent randomized controlled trials

PURPOSE

Walking and mind-body therapies (MBTs) are commonly recommended to relieve pain and improve function in patients with chronic low back pain (CLBP). The purpose of this study was to compare the effectiveness of walking and MBTs in CLBP.

METHODS

We included randomized controlled trials (RCTs) comparing walking or MBTs to any other intervention or control in adults with CLBP. Studies were identified through PubMed, Cochrane Library, PsycINFO, Scopus, and ScienceDirect databases. The research was limited to studies published in English and French between January 2008 and December 2018. Two reviewers independently selected the studies, extracted data, and assessed studies quality using the Physiotherapy Evidence Database (PEDro) scale. Statistical analyses were performed under a random-effects model. We analyzed pain and activity limitation, with the calculation of standardized mean differences and 95% confidence intervals for the different treatment effects.

RESULTS

Thirty one randomized controlled trials involving 3193 participants were analyzed. Walking was as effective as control interventions in the short-term and slightly superior in the intermediate term with respect to pain (Standardized mean differences (SMD)  = -0.34; 95% CI, -0.65 to -0.03; P = .03) and activity limitation (SMD = -0.30; 95% CI, -0.50 to -0.10; P = .003). In contrast, yoga was more effective than control interventions in the short term in terms of pain (SMD = -1.47; 95% CI, -2.26 to -0.68; P = .0003) and activity limitation (SMD = -1.17; 95% CI, -1.80 to -0.55; P = .0002). Yoga was no longer superior to the control interventions for pain at the 6-month follow-up.

CONCLUSION

MBTs, especially yoga, seem to be more effective in the short term, and walking seems to be more effective in the intermediate term, for the relief of pain and activity limitation in patients with CLBP. A combination of walking and MBTs fits the biopsychosocial model and might be valuable therapy for CLBP throughout follow-up due to combined effects.

Guideline summary review: an evidence-based clinical guideline for the diagnosis and treatment of low back pain

BACKGROUND CONTEXT

The North American Spine Society's (NASS) Evidence Based Clinical Guideline for the Diagnosis and Treatment of Low Back Pain features evidence-based recommendations for diagnosing and treating adult patients with nonspecific low back pain. The guideline is intended to reflect contemporary treatment concepts for nonspecific low back pain as reflected in the highest quality clinical literature available on this subject as of February 2016.

PURPOSE

The purpose of the guideline is to provide an evidence-based educational tool to assist spine specialists when making clinical decisions for adult patients with nonspecific low back pain. This article provides a brief summary of the evidence-based guideline recommendations for diagnosing and treating patients with this condition.

STUDY DESIGN

This is a guideline summary review.

METHODS

This guideline is the product of the Low Back Pain Work Group of NASS' Evidence-Based Clinical Guideline Development Committee. The methods used to develop this guideline are detailed in the complete guideline and technical report available on the NASS website. In brief, a multidisciplinary work group of spine care specialists convened to identify clinical questions to address in the guideline. The literature search strategy was developed in consultation with medical librarians. Upon completion of the systematic literature search, evidence relevant to the clinical questions posed in the guideline was reviewed. Work group members utilized NASS evidentiary table templates to summarize study conclusions, identify study strengths and weaknesses, and assign levels of evidence. Work group members participated in webcasts and in-person recommendation meetings to update and formulate evidence-based recommendations and incorporate expert opinion when necessary. The draft guideline was submitted to an internal and external peer review process and ultimately approved by the NASS Board of Directors.

RESULTS

Eighty-two clinical questions were addressed, and the answers are summarized in this article. The respective recommendations were graded according to the levels of evidence of the supporting literature.

CONCLUSIONS

The evidence-based clinical guideline has been created using techniques of evidence-based medicine and best available evidence to aid practitioners in the diagnosis and treatment of adult patients with nonspecific low back pain. The entire guideline document, including the evidentiary tables, literature search parameters, literature attrition flowchart, suggestions for future research, and all of the references, is available electronically on the NASS website at https://www.spine.org/ResearchClinicalCare/QualityImprovement/ClinicalGuidelines.aspx.

The Effectiveness of Digital Health Interventions in the Management of Musculoskeletal Conditions: Systematic Literature Review

Background

Musculoskeletal conditions are the second greatest contributor to disability worldwide and have significant individual, societal, and economic implications. Due to the growing burden of musculoskeletal disability, an integrated and strategic response is urgently required. Digital health interventions provide high-reach, low-cost, readily accessible, and scalable interventions for large patient populations that address time and resource constraints.

Objective

This review aimed to investigate if digital health interventions are effective in reducing pain and functional disability in patients with musculoskeletal conditions.

Methods

A systematic review was undertaken to address the research objective. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The review protocol was registered with the International Prospective Register of Systematic Reviews before commencement of the study. The following databases were searched: Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica database (EMBASE), Cumulative Index to Nursing and Allied Health Literature, and Scopus from January 1, 2000, to November 15, 2019, using search terms and database specific−medical subject headings terms in various combinations appropriate to the research objective.

Results

A total of 19 English language studies were eligible for inclusion. Of the 19 studies that assessed musculoskeletal pain, 9 reported statistically significant reductions following digital intervention. In all, 16 studies investigated functional disability; 10 studies showed a statistically significant improvement. Significant improvements were also found in a range of additional outcomes. Due to the heterogeneity of the results, a meta-analysis was not feasible.

Conclusions

This review has demonstrated that digital health interventions have some clinical benefits in the management of musculoskeletal conditions for pain and functional disability. Digital health interventions have the potential to contribute positively toward reducing the multifaceted burden of musculoskeletal conditions to the individual, economy, and society.

Forty one adults referred for assessment and advice for any mild/moderate LTMCs. doing <120minutes of moderate intensity activity per week.

INTERVENTIONS

Participants randomised to: 1. Usual care: one usual physiotherapy advice and assessment session, including setting a physical activity goal and one follow up session (8 weeks). 2. "Walk30×5": session one, usual care plus intervention of walking programme. Participants were shown the website and podcasts and practiced how to use them. One follow up session (8 weeks).

OUTCOME MEASURES

Primary: timed six minute walk test (T6MWT). Secondary: step count, self-reported pain, fatigue, mood, self-efficacy, happiness, objective blood pressure, peak expiratory flow rate, and self-report and accelerometer measured physical activity.

RESULTS

Recruitment target achieved. No adverse events occurred. Adherence was high and the intervention acceptable. Loss to follow up n=3 (7%) at 3 months, n=8 (20%) at 6 months. T6MWT and step count proved suitable outcomes, unlike accelerometry. Estimated sample size for a definitive trial is 216.

CONCLUSIONS

"Walk30×5" is ready for evaluation in a future, appropriately powered (n=216), phase III trial. If effective, the intervention will provide a cheap, highly accessible intervention to enable people with mild/moderate LTMCs to achieve UK physical activity guidelines.

A Systematic Review and Meta-analysis of Unguided Electronic and Mobile Health Technologies for Chronic Pain—Is It Time to Start Prescribing Electronic Health Applications?

Objective

Electronic (eHealth) and mobile (mHealth) technologies may be a useful adjunct to clinicians treating patients with chronic pain. The primary aim of this study was to investigate the effects of eHealth and mHealth interventions that do not require clinician contact or feedback on pain-related outcomes recommended by the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) guidelines in adults with chronic pain.

Methods

We searched four databases and included English language randomized controlled trials of ambulatory adults with chronic pain from January, 1 2000, to January 31, 2018, with interventions that are independent of clinician contact or feedback. In the meta-analysis, outcomes were assessed at short- (three months or less), intermediate- (four to six months), and long-term (seven or more months) follow-up.

Results

Seventeen randomized controlled trials (N = 2,496) were included in the meta-analysis. Both eHealth and mHealth interventions had a significant effect on pain intensity at short- and intermediate-term follow-up. Similarly, a significant but small effect was observed for depression at short- and intermediate-term follow-up and self-efficacy at short-term follow-up. Finally, a significant effect was observed for pain catastrophizing at short-term follow-up.

Conclusions

eHealth and mHealth interventions had significant effects on multiple short- and intermediate-term outcome measures recommended in the IMMPACT guidelines. Given widespread availability and low cost to patients, clinicians treating patients with chronic pain could consider using eHealth and mHealth interventions as part of a multidisciplinary pain treatment strategy.

Social Cognitive Theories and Electronic Health Design: Scoping Review

Background

There are several social cognitive theories (SCTs) and models that support platform design in electronic health (eHealth) promotion trials. The rationale for this scoping review was to determine how social design features (informational aid, expressive support, gaming, and tailored content) are used to promote self-efficacy, engagement, knowledge, and behavior change.

Objective

This study aimed to review a broad spectrum of digital health interventions in the literature seeking trials that use SCTs for the design of eHealth applications.

Methods

The author conducted a systematic scoping review of 161 Web-based health interventions from published randomized clinical trials using 1 or more tools to address the social cognitive determinants in their website design from January 2006 to April 2016. An iterative approach was used in the selection of studies and data extraction. The studies were analyzed for quality and coded for type of social design features employed.

Results

Expressive interaction tools were found in 48.6% (54/111) of studies categorized as a strong recommendation by the Joanna Briggs Institute criteria. Overall, less than half of the studies addressed participant social support and motivational needs (43.8%). The vast majority of studies (100%) relied on the use of the Web for delivery of informational aid and tailored content for the individual participant (75.9%).

Conclusions

This review fills a research gap by linking social theory to Web strategy to improve the impact and sustainability of eHealth interventions. A Digital Health Intervention Model was developed to provide a framework to enhance future Web-based health intervention design and execution.

An Evaluation of the Effectiveness of the Modalities Used to Deliver Electronic Health Interventions for Chronic Pain: Systematic Review With Network Meta-Analysis

BACKGROUND

Electronic health (eHealth) is the use of information and communication technology in the context of health care and health research. Recently, there has been a rise in the number of eHealth modalities and the frequency with which they are used to deliver technology-assisted self-management interventions for people living with chronic pain. However, there has been little or no research directly comparing these eHealth modalities.

OBJECTIVE

The aim of this systematic review with a network meta-analysis (NMA) is to compare the effectiveness of eHealth modalities in the context of chronic pain.

METHODS

Randomized controlled trials (N>20 per arm) that investigated interventions for adults with chronic pain, delivered via an eHealth modality, were included. Included studies were categorized into their primary node of delivery. Data were extracted on the primary outcome, pain interference, and secondary outcomes, pain severity, psychological distress, and health-related quality of life. Pairwise meta-analyses were undertaken where possible, and an NMA was conducted to generate indirect comparisons and rankings of modalities for reducing pain interference.

RESULTS

The search returned 18,470 studies with 18,349 being excluded (duplicates=2310; title and abstract=16,039). Of the remaining papers, 30 studies with 5394 randomized participants were included in the review. Rankings tentatively indicated that modern eHealth modalities are the most effective, with a 43% chance that mobile apps delivered the most effective interventions, followed by a 34% chance that interventions delivered via virtual reality were the most effective.

CONCLUSIONS

This systematic review with an NMA generated comparisons between eHealth modalities previously not compared to determine which delivered the most effective interventions for the reduction of pain interference in chronic pain patients. There are limitations with this review, in particular, the underrepresented nature of some eHealth modalities included in the analysis. However, in the event that the review is regularly updated, a clear ranking of eHealth modalities for the reduction of pain interference will emerge.

Is occupational or leisure physical activity associated with low back pain? Insights from a cross-sectional study of 1059 participants

BACKGROUND

Low back pain is a highly prevalent and disabling musculoskeletal disorder. Physical activity is widely used as a prevention strategy for numerous musculoskeletal disorders; however, there is still conflicting evidence as to whether physical activity is a protective or risk factor for low back pain or whether activity levels differ between people with and without low back pain.

OBJECTIVE

To investigate the association between low back pain and different types (occupational and leisure) and intensities (moderate and vigorous) of physical activity.

METHODS

This is cross-sectional observational study. We included in this study a total of 1059 individuals recruited from a Spanish twin registry with data available on low back pain.

OUTCOME

Self-reported leisure and occupational physical activity were the explanatory variables. The low back pain outcome used in this study was recurrent low back pain.

RESULTS

Our results indicate that leisure physical activity is associated with a lower prevalence of recurrent low back pain. In contrast, occupational physical activity, such as carrying, lifting heavy weight while inclined, awkward postures (e.g. bending, twisting, squatting, and kneeling) are associated with a higher prevalence of recurrent low back pain. There was no statistically significant association between other occupational physical activities, such as sitting or standing, and low back pain.

CONCLUSION

Leisure and occupational physical activity are likely to have an opposed impact on low back pain. While leisure physical activity appears to be protective, occupational physical activity appears to be harmful to low back pain. Future longitudinal studies should assist in formulating guidelines addressing specific types and intensity of physical activity aimed at effectively preventing low back pain.

Use of Wearable Activity Trackers to Improve Physical Activity Behavior in Patients With Rheumatic and Musculoskeletal Diseases: A Systematic Review and Meta-Analysis

OBJECTIVE

Wearable activity trackers (WATs) could be a promising strategy to improve physical activity in patients with rheumatic and musculoskeletal diseases (RMDs). The aim was to assess the adherence to and effectiveness of WATs to increase physical activity levels in patients with RMDs.

METHODS

A systematic review was performed to identify all cohorts and controlled trials evaluating WATs in patients with RMDs, published between 2000 and 2018, by searching Medline, Embase, PsycINFO, and Cochrane. Data collected pertained to adherence, effectiveness on physical activity, or effectiveness on symptoms (pain, function, quality of life, or fatigue). Meta-analyses were performed with a random effects model.

RESULTS

Of 2,806 references, 17 studies were included, with a total of 1,588 patients: 8 studies (47%) in osteoarthritis, 5 (29%) in low-back pain, and 3 (18%) in inflammatory arthritis. Adherence assessed in 4 studies was high (weighted mean ± SD time worn was 92.7% ± 4.6%). A significant increase in physical activity was noted (mean difference 1,520 steps [95% confidence interval (95% CI) 580, 2,460], I² = 77%; or 16 minutes [95% CI 2, 29] of moderate-to-vigorous physical activity, I² = 0%). A significant increase in pain was found for long interventions (>8 weeks) (standardized mean difference 0.25 [95% CI 0.07, 0.43], I² = 0%).

CONCLUSION

WATs in patients with RMDs had a high short-term adherence, with a significant increase in the number of steps and time spent in moderate-to-vigorous physical activity, although pain should be monitored. WATs may be an effective option to increase physical activity in this at-risk population.

Improving Blood Pressure Among African Americans With Hypertension Using a Mobile Health Approach (the MI-BP App): Protocol for a Randomized Controlled Trial

BACKGROUND

African Americans shoulder significant disparities related to hypertension (HTN), which is a serious public health problem in the city of Detroit, Michigan, where more than 80% of the population is African American. Connectivity through smartphones, use of home blood pressure (BP) monitoring, and newly developed mobile health (mHealth) interventions can facilitate behavioral changes and may improve long-term self-care for chronic conditions, but implementation of a combined approach utilizing these methods has not been tested among African American patients with uncontrolled HTN. Since African Americans are more likely than other racial or ethnic subgroups to utilize the emergency department (ED) for ambulatory care, this presents an opportunity to intervene on a population that is otherwise difficult to reach.

OBJECTIVE

The MI-BP app aims to reduce health disparities related to HTN in the community by employing a user-centered intervention focused on self-BP monitoring, physical activity, reduced sodium intake, and medication adherence. We seek to test the efficacy of MI-BP, an mHealth app for HTN self-management, on BP control (primary aim), physical activity, sodium intake, and medication adherence (secondary aim) in African Americans with HTN. This study also seeks to evaluate the cost-effectiveness of MI-BP when compared with usual care methods.

METHODS

This is a 1-year randomized controlled trial that will recruit individuals who have uncontrolled HTN from 2 EDs in the city of Detroit, with a planned sample size of 396 randomized participants. To be eligible for inclusion, potential participants must be African American, 25 to 70 years old, previously diagnosed with HTN, have a smartphone compatible with MI-BP, and have uncontrolled BP at triage and on repeat measurement at least 1-hour post triage vitals. Once a participant is deemed eligible, all study procedures and subsequent follow-up visits (8 in total) are conducted at the Wayne State University Clinical Research Service Center. We seek to determine the effect of MI-BP on BP for 1 year (using BP control and mean systolic BP as coprimary outcomes and physical activity, sodium intake, and medication adherence as secondary outcomes) compared with usual care controls.

RESULTS

Recruitment for this study began in January 2018. The study will continue through 2021.

CONCLUSIONS

As the first of its kind conducted in an ED setting, MI-BP was designed to document the efficacy and acceptability of a multicomponent mHealth approach to help African Americans with uncontrolled BP modify their lifestyle to better manage their HTN. We expect to lay the foundation to sustainably reduce HTN-related health disparities through better integration of multiple behavior self-monitoring and improve outcomes for those who traditionally rely on the ED for chronic disease care.

The effectiveness of incidental physical activity interventions compared to other interventions in the management of people with low back pain: A systematic review and meta-analysis of randomised controlled trials

OBJECTIVES

To investigate the effectiveness of incidental (non-structured) physical activity interventions for the management of people with low back pain (LBP).

DESIGN

Systematic review and meta-analyses of randomised controlled trials.

SETTING

Eligible published trials from the earliest date available to November 2017.

PARTICIPANTS

People with non-specific LBP aged 18 years or over.

OUTCOME MEASURES

Pain, disability and physical activity-related outcomes.

RESULTS

Three trials were included (including a total of 422 participants). The quality of trials, assessed by PEDro scale, was high (7 out of 10). For pain, the pooled results did not show any significant effects between the incidental physical activity intervention and other interventions at any time point. For disability, incidental physical activity was not statistically more effective than other interventions at short-term; however, the pooled results favoured incidental physical activity at intermediate-term (weighted mean difference (WMD) = -6.05, 95%CI: -10.39 to -1.71) and long-term (WMD = -6.40 95%CI: -11.68 to -1.12) follow-ups among participants with chronic LBP. The overall quality of evidence was rated "moderate-quality" based on the GRADE system.

CONCLUSIONS

The incidental physical activity intervention provided improvement in disability in intermediate- and long-term for people with chronic LBP, although this improvement was small and may not be clinically significant.

Variations of handheld loads increase the range of motion of the lumbar spine without compromising local dynamic stability during walking

BACKGROUND

Walking is often considered a beneficial management strategy for certain populations of low back pain patients. However, little is known about how simple challenges that people often encounter, such as carrying loads in the hands, affect the low back during walking.

RESEARCH QUESTION

How do variations in hand loading affect arm swing, lumbar spine range of motion (ROM), and lumbar spine local dynamic stability (LDS) during walking?

METHODS

Sixteen young healthy participants (8 female) performed nine treadmill walking trials, each at 1.25 m/s for 3 consecutive minutes. Conditions manipulated the magnitude of hand loads (unloaded, low, high) and location of hand loads (directly in hands, in bags). Kinematic markers were used to measure sagittal plane arm swing, 3D lumbar spine ROM, and lumbar spine LDS during each trial.

RESULTS

Arm swing was significantly (p < 0.001) reduced as load increased directly in the hands; however, when held in bags load magnitude had no effect. Further, arm swing was significantly (p < 0.0001) lower when loads were held in bags. Lumbar flexion/extension ROM was greatest with the low load compared to both unloaded (p = 0.012) and high load (p = 0.0717) conditions, and was also greater (p < 0.0001) with loads held directly in the hands compared to loads in bags. Despite these changes in lumbar spine ROM, lumbar spine LDS was not significantly affected by any of the variations in hand loading.

SIGNIFICANCE

The greater lumbar spine cyclic motion, elicited by low hand loads held directly in the hands during walking, may be beneficial to the health of the low back. No changes in lumbar LDS were found, thereby suggesting that the small, likely beneficial, increases in lumbar spine ROM are well controlled by the motor control system and do not create an increased risk of injury.

An mHealth App for Self-Management of Chronic Lower Back Pain (Limbr): Pilot Study

Background

Although mobile health (mHealth) interventions can help improve outcomes among patients with chronic lower back pain (CLBP), many available mHealth apps offer content that is not evidence based. Limbr was designed to enhance self-management of CLBP by packaging self-directed rehabilitation tutorial videos, visual self-report tools, remote health coach support, and activity tracking into a suite of mobile phone apps, including Your Activities of Daily Living, an image-based tool for quantifying pain-related disability.

Objective

The aim is to (1) describe patient engagement with the Limbr program, (2) describe patient-perceived utility of the Limbr program, and (3) assess the validity of the Your Activities of Daily Living module for quantifying functional status among patients with CLBP.

Methods

This was a single-arm trial utilizing a convenience sample of 93 adult patients with discogenic back pain who visited a single physiatrist from January 2016 to February 2017. Eligible patients were enrolled in 3-month physical therapy program and received the Limbr mobile phone app suite for iOS or Android. The program included three daily visual self-reports to assess pain, activity level, and medication/coping mechanisms; rehabilitation video tutorials; passive activity-level measurement; and chat-based health coaching. Patient characteristics, patient engagement, and perceived utility were analyzed descriptively. Associations between participant characteristics and program interaction were analyzed using multiple linear regression. Associations between Your Activities of Daily Living and Oswestry Disability Index (ODI) assessments were examined using Pearson correlation and hierarchical linear modeling.

Results

A total of 93 participants were enrolled; of these, 35 (38%) completed the program (age: mean 46, SD 16 years; female: 22/35, 63%). More than half of completers finished assessments at least every 3 days and 70% (19/27) used the rehabilitation component at least once a week. Among respondents to a Web-based feedback survey, 76% (16/21) found the daily notifications helped them remember to complete their exercises, 81% (17/21) found the system easy to use, and 62% (13/21) rated their overall experience good or excellent. Baseline Your Activities of Daily Living score was a significant predictor of baseline ODI score, with ODI increasing by 0.30 units for every 1-unit increase in Your Activities of Daily Living (P<.001). Similarly, hierarchical linear modeling analysis indicated that Your Activities of Daily Living daily assessment scores were significant predictors of ODI scores over the course of the study (P=.01).

Conclusions

Engagement among participants who completed the Limbr program was high, and program utility was rated positively by most respondents. Your Activities of Daily Living was significantly associated with ODI scores, supporting the validity of this novel tool. Future studies should assess the effect of Limbr on clinical outcomes, evaluate its use among a wider patient sample, and explore strategies for reducing attrition.

Pain Energy Model of Mobility Limitation in the Older Adult

Background

Chronic pain is prevalent, costly, and disabling among older adults. Although mobility decline is inevitable with aging, it is clear, from current evidence, that older adults with chronic pain experience a greater rate of functional mobility decline than their pain-free peers. Past studies suggest that pain expedites the age-related decline in functional mobility; however, the pathways through which pain affects mobility remain unclear. Gerontological experts hypothesize that the age-related decline in mobility may be driven by alterations in energy expenditure; these concepts are outlined in a model known as the Energetic Pathway of Mobility Loss. Pain may play a critical role in this process through a pathway of energetic inefficiency, physical inactivity, and decreased capacity.

Purpose

The purposes of this article are to 1) summarize the current literature that supports the Energetic Pathway of Mobility Loss model and 2) propose a new framework, known as the Pain Energy Model, to clarify how the disablement process may be amplified among older adults with painful conditions.

Conclusion

This new framework is designed to generate new clinical research and to suggest new clinical implications for older adults with painful conditions by identifying key steps and potential treatment targets in the pathway to functional mobility decline.
