Spinal segmental stabilisation exercises for chronic low back pain: programme adherence and its influence on clinical outcome

Disability reduction following a lumbar stabilization exercise program for low back pain: large vs. small improvement subgroup analyses of physical and psychological variables

BACKGROUND

Little is known about why patients with low back pain (LBP) respond differently to treatment, and more specifically, to a lumbar stabilization exercise program. As a first step toward answering this question, the present study evaluates how subgroups of patients who demonstrate large and small clinical improvements differ in terms of physical and psychological changes during treatment.

METHODS

Participants (n = 110) performed the exercise program (clinical sessions and home exercises) over eight weeks, with 100 retained at six-month follow-up. Physical measures (lumbar segmental instability, motor control impairments, range of motion, trunk muscle endurance and physical performance tests) were collected twice (baseline, end of treatment), while psychological measures (fear-avoidance beliefs, pain catastrophizing, psychological distress, illness perceptions, outcome expectations) were collected at four time points (baseline, mid-treatment, end of treatment, follow-up). The participants were divided into three subgroups (large, moderate and small clinical improvements) based on the change of perceived disability scores. ANOVA for repeated measure compared well-contrasted subgroups (large vs. small improvement) at different times to test for SUBGROUP × TIME interactions.

RESULTS

Statistically significant interactions were observed for several physical and psychological measures. In all these interactions, the large- and small-improvement subgroups were equivalent at baseline, but the large-improvement subgroup showed more improvements over time compared to the small-improvement subgroup. For psychological measures only (fear-avoidance beliefs, pain catastrophizing, illness perceptions), between-group differences reached moderate to strong effect sizes, at the end of treatment and follow-up.

CONCLUSIONS

The large-improvement subgroup showed more improvement than the small-improvement subgroup with regard to physical factors typically targeted by this specific exercise program as well as for psychological factors that are known to influence clinical outcomes.

The Added Value of Face-to-Face Supervision to a Therapeutic Exercise-Based App in the Management of Patients with Chronic Low Back Pain: A Randomized Clinical Trial

Low back pain (LBP) is a significant global health challenge due to its high prevalence, and chronicity and recurrence rates, with projections suggesting an increase in the next years due to population growth and aging. The chronic and recurrent nature of LBP, responsible for a significant percentage of years lived with disability, underscores the need for effective management strategies, including self-management strategies advocated by current guidelines, to empower patients and potentially improve healthcare efficiency and clinical outcomes. Therefore, the aim of this study was to analyze the added value of face-to-face visits in patients with chronic LBP undergoing a self-management program based on therapeutic exercises on pain intensity, disability, quality of life and treatment adherence and satisfaction. A randomized clinical trial was conducted, allocating 49 patients into a experimental group with a mobile health (mHealth) app usage and face-to-face sessions and 49 patients into an active control group without face-to-face sessions. Pain intensity, disability and quality of life were assessed at baseline, 4 weeks postintervention and 12 weeks postintervention. Patients' satisfaction and adherence were assessed at the end of the study. The multivariate general model revealed no statistically significant time × group interaction for any outcome (p > 0.0068) but mental quality of life (p = 0.006). Within-group differences revealed significant improvements for all the clinical indicators (all, p < 0.001). Patients allocated to the experimental group reported greater satisfaction and adherence (both, p < 0.001) compared to the control group. The use of mHealth apps such as Healthy Back® as part of digital health initiatives may serve as a beneficial approach to enhance the management of LBP.

Barriers and factors associated with adherence to a home exercise program of adults with musculoskeletal pain

BACKGROUND

Home exercise programs (HEPs) are cost-effective and efficacious treatments for musculoskeletal pain conditions. Although HEPs are an important part of the continuum of care, non-adherence limits their effectiveness.

OBJECTIVE

The objective of this study was to examine adherence and specific barriers to clinician-prescribed HEPs in adults with musculoskeletal pain.

METHODS

A cross-sectional study was conducted with a total of 300 patients presenting to an outpatient pain clinic in an academic medical center. Participants' self-reported information, including HEP completion frequency and barriers, was collected through a survey.

RESULTS

The participants' mean age was 54.1 ± 15.8 years (females = 133 (65.5%)). Of 203 participants, 99 (48.8%) adhered to HEP, 56 (27.6%) partially adhered, and 48 (23.6%) did not adhere. One hundred eighty-seven (92.1%) participants reported receiving adequate instructions, and 175 (86.2%) reported receiving instructional materials. Age and "sufficient instructions" were found to be significant determinants of adherence (p< 0.05), while gender and handouts were not (p> 0.05). Pain in more than one body part was significantly (p< 0.05) associated with motivational barriers for non-adherence.

CONCLUSION

Age and participants' perception of sufficient instructions were significant factors for non-adherence. These results emphasize the importance of therapist-provided instructions to overcome barriers to adherence.

Determinants of outcomes for patients with chronic low back pain and fear-avoidance beliefs following treatment with specific stabilisation exercises

BACKGROUND

Specific stabilisation exercises (SSE) can combat the debilitating effects of chronic non-specific low back pain (CLBP), improve disability, pain and fear-avoidance beliefs (FAB).

OBJECTIVE

To elicit the determinants of outcome in patients with CLBP with associated FABs after treatment with SSE.

METHOD

Twenty-nine patients (20 females) with CLBP were classified using FAB questionnaire into high or low Work and Physical Activity (PA) subscales. After 4-week treatment, evaluations were done for pain, disability and lumbar spine active range of motion (AROM). Data was analysed exploratory-descriptively with a significance level set at p< 0.05.

RESULTS

Participants were aged 55.24 ± 11.91 years. They scored 19 (65.5%) and 5 (17.2%) respectively on Work and PA subscales. The post-intervention evaluation showed significant differences in all outcomes, but no significant difference between patients with high or low FAB scores for both subscales. PA scores correlated significantly with pain while work scores correlated significantly with disability. Participants' gender predicted disability, pain and AROM with moderate to large effect sizes.

CONCLUSION

SSE can potentially improve disability, pain and range of motion for patients with chronic low back pain regardless of FABQ status. Gender and baseline patient status are potential determinants of outcome of treatment using SSE.

Strategies to facilitate and tools to measure non-specific low back pain patients' adherence to physiotherapy - A two-stage systematic review

BACKGROUND

Sustainable management for non-specific low back pain relies on adherence. This requires effective strategies to facilitate but also tools to measure adherence to physiotherapy.

OBJECTIVE

This two-stage systematic review aims to identify (1) tools to measure non-specific back pain patients' adherence to physiotherapy and (2) the most effective strategy to facilitate patients' adherence to physiotherapy.

METHOD

PubMed, Cochrane, PEDro, and Web of Science were searched for English language studies measuring adherence in adults with low back pain. Following PRISMA recommendations, scoping review methods were used to identify measurement tools (stage 1). The effectiveness of interventions (stage 2), followed a predefined systematic search strategy. Two independent reviewers selected eligible studies (software Rayyan), analyzed these for risk of bias using the Downs and Black checklist. Data relevant to assess adherence were collected in a predesigned data extraction table. Results were heterogeneous and hence summarized narratively.

RESULTS

Twenty-one studies were included for stage 1 and 16 for stage 2. Identified were 6 different tools to measure adherence. The most used tool was an exercise diary; the most common more multidimensional tool was the Sports Injury Rehabilitation Adherence Scale. Most included studies were not designed to improve or measure adherence but used adherence as a secondary outcome for new exercise programs. The most promising strategies for facilitating adherence were based on cognitive behavioral principles.

CONCLUSION

Future studies should focus on the development of multidimensional strategies to facilitate adherence to physiotherapy and appropriate tools to measure all aspects of adherence.

Needs and Attitudes of Older Chronic Back Pain Patients towards a Wearable for Ultrasound Biofeedback during Stabilization Exercises: A Qualitative Analysis

Chronic back pain has a high prevalence, especially in older adults, and seriously affects sufferers' quality of life. Segmental stabilization exercise (SSE) is often used during physiotherapy to enhance core stability. The execution of SSE requires the selective contraction of deep abdominal and back muscles. Motor learning can be supported using ultrasound imaging as visual biofeedback. ULTRAWEAR is a mobile ultrasound system that provides deep learning-based biofeedback on SSE execution, which is currently under development. We interviewed 15 older chronic back pain patients (CBPPs) to investigate their pain management behavior, experience with SSE, as well as their needs and requirements for ULTRAWEAR. We also gathered information about future-usage scenarios. CBPPs reported a high willingness to use the system as a feedback tool both in physiotherapeutic practices and at home. The automated detection and evaluation of muscle contraction states was highlighted as a major benefit of the system compared to the more subjective feedback provided by traditional methods such as palpation. The system to be developed was perceived as a helpful solution to support learning about SSE.

Home Exercise Programs Are Infrequently Prescribed in Trials of Supervised Exercise for Individuals With Low Back Pain: A Scoping Review of 292 Randomized Controlled Trials

OBJECTIVES: To (1) determine how often home exercise programs (HEPs) are prescribed in supervised exercise trials for low back pain (LBP) and (2) describe characteristics of the HEP programs (design, purpose, dose, and adherence). DESIGN: Scoping review. LITERATURE SEARCH: PubMed, CINAHL, and Ovid MEDLINE were searched from January 1, 2010, to August 17, 2021. STUDY SELECTION CRITERIA: Randomized controlled trials that included adults with LBP who received exercise interventions. DATA SYNTHESIS: The presence or absence of a prescribed HEP and any details of the HEP including design, dose, and adherence were extracted and summarized. RESULTS: Of 2689 potentially relevant trials, 292 were eligible for inclusion. Ninety-four trials (32%) included a HEP. The most commonly prescribed home exercises were core stability, trunk strengthening, and motor control exercises. There was great variation in the frequency and duration with which HEPs were prescribed. Adherence to HEPs was measured in fewer than half of the trials, and the methods for measuring adherence were inconsistent. Adherence to HEPs ranged from 29% to 82% in the 21 trials that reported adherence. CONCLUSION: Home exercise programs are not regularly prescribed in supervised exercise trials for LBP. There was considerable variation in prescribing HEPs and monitoring exercise adherence in trials of exercise-based treatments for adults with LBP. There is no consistent method used to measure participants' adherence to HEPs, and adherence percentages vary widely. J Orthop Sports Phys Ther 2023;53(3):120-142.

Understanding barriers to adherence to home exercise programs in patients with musculoskeletal neck pain

BACKGROUND

Home exercise program (HEP) prescription is commonplace in physical therapy (PT). Adherence to HEPs is generally poor, with non-adherence as high as 70%. Poor adherence may negatively impact outcomes.

OBJECTIVES

To (i) qualitatively assess patients' thoughts and beliefs regarding HEP performance and (ii) quantitatively define the relationship between adherence to HEPs and functional outcomes and identify variables that impact adherence.

DESIGN

Mixed-methods.

METHOD

Part 1 involved semi-structured interviews with patients attending PT for neck pain. Responses were assessed using thematic analysis. Part 2 involved a retrospective chart review of patients seen in outpatient PT for neck pain. Between-group (adherent and non-adherent) differences in functional scores were analyzed using a linear mixed model. Sex, age, and functional score data was entered into a regression model to explore their ability to predict adherence.

RESULTS

25 participants were interviewed. Qualitative analysis revealed the following themes associated with adherence to a HEP: (i) prior PT, (ii) observability of outcomes, (iii) expectations of PT, and (iv) experience of pain. Retrospective data from 187 patients was analyzed. Functional scores at discharge were significantly higher (p = 0.03, mean difference = 12.4) in the adherent group. Age (OR = 0.98; 95% CI = 0.93-1.02), male sex (OR = 1.23; 95% CI = 0.22-6.91), and functional scores at intake (OR = 0.99; 95% CI = 0.92-1.07) were not significant predictors of non-adherence.

CONCLUSIONS

Individual patient experiences such as delayed improvement in symptoms and/or experience of pain associated with HEP performance may contribute to poor adherence to HEPs. Adherence to a HEP was associated with superior functional outcomes compared to non-adherence. Age, sex, and functional scores were not predictors of non-adherence.

Factors impacting adherence to an exercise-based physical therapy program for individuals with low back pain

Background/Objective

Exercise-based rehabilitation is a conservative management approach for individuals with low back pain. However, adherence rates for conservative management are often low and the reasons for this are not well described. The objective of this study was to evaluate predictors of adherence and patient-reported reasons for non-adherence after ceasing a supervised exercise-based rehabilitation program in individuals with low back pain.

Design

Retrospective observational study.

Methods

Data was retrospectively analyzed from 5 rehabilitation clinics utilizing a standardized exercise-based rehabilitation program. Baseline demographics, diagnosis and symptom specific features, visit number, and discontinuation profiles were quantified for 2,243 patients who underwent the program.

Results

Forty-three percent (43%) of participants were adherent to the program, with the majority (31.7%) discontinuing treatment prior to completion due to logistic and accessibility issues. Another 13.2% discontinued prior to the prescribed duration due to clinically significant improvements in pain and/or disability without formal discharge evaluation, whereas 8.3% did not continue due to lack of improvement. Finally, 6.0% were discharged for related and unrelated medical reasons including surgery. Individuals diagnosed with disc pathology were most likely to be adherent to the program.

Limitations

This study was a retrospective chart review with missing data for some variables. Future studies with a prospective design would increase quality of evidence.

Conclusions

The majority of individuals prescribed an in-clinic exercise-based rehabilitation program are non-adherent. Patient diagnosis was the most important predictor of adherence. For those who were not adherent, important barriers include personal issues, insufficient insurance authorization and lack of geographic accessibility.

Derivation of clinical prediction rules for identifying patients with non-acute low back pain who respond best to a lumbar stabilization exercise program at post-treatment and six-month follow-up

Low back pain (LBP) remains one of the most common and incapacitating health conditions worldwide. Clinical guidelines recommend exercise programs after the acute phase, but clinical effects are modest when assessed at a population level. Research needs to determine who is likely to benefit from specific exercise interventions, based on clinical presentation. This study aimed to derive clinical prediction rules (CPRs) for treatment success, using a lumbar stabilization exercise program (LSEP), at the end of treatment and at six-month follow-up. The eight-week LSEP, including clinical sessions and home exercises, was completed by 110 participants with non-acute LBP, with 100 retained at the six-month follow-up. Physical (lumbar segmental instability, motor control impairments, posture and range of motion, trunk muscle endurance and physical performance tests) and psychological (related to fear-avoidance and home-exercise adherence) measures were collected at a baseline clinical exam. Multivariate logistic regression models were used to predict clinical success, as defined by ≥50% decrease in the Oswestry Disability Index. CPRs were derived for success at program completion (T8) and six-month follow-up (T34), negotiating between predictive ability and clinical usability. The chosen CPRs contained four (T8) and three (T34) clinical tests, all theoretically related to spinal instability, making these CPRs specific to the treatment provided (LSEP). The chosen CPRs provided a positive likelihood ratio of 17.9 (T8) and 8.2 (T34), when two or more tests were positive. When applying these CPRs, the probability of treatment success rose from 49% to 96% at T8 and from 53% to 92% at T34. These results support the further development of these CPRs by proceeding to the validation stage.

The 3-Month Effectiveness of a Stratified Blended Physiotherapy Intervention in Patients With Nonspecific Low Back Pain: Cluster Randomized Controlled Trial

Background

Patient education, home-based exercise therapy, and advice on returning to normal activities are established physiotherapeutic treatment options for patients with nonspecific low back pain (LBP). However, the effectiveness of physiotherapy interventions on health-related outcomes largely depends on patient self-management and adherence to exercise and physical activity recommendations. e-Exercise LBP is a recently developed stratified blended care intervention comprising a smartphone app integrated with face-to-face physiotherapy treatment. Following the promising effects of web-based applications on patients’ self-management skills and adherence to exercise and physical activity recommendations, it is hypothesized that e-Exercise LBP will improve patients’ physical functioning.

Objective

This study aims to investigate the short-term (3 months) effectiveness of stratified blended physiotherapy (e-Exercise LBP) on physical functioning in comparison with face-to-face physiotherapy in patients with nonspecific LBP.

Methods

The study design was a multicenter cluster randomized controlled trial with intention-to-treat analysis. Patients with nonspecific LBP aged ≥18 years were asked to participate in the study. The patients were treated with either stratified blended physiotherapy or face-to-face physiotherapy. Both interventions were conducted according to the Dutch physiotherapy guidelines for nonspecific LBP. Blended physiotherapy was stratified according to the patients’ risk of developing persistent LBP using the Keele STarT Back Screening Tool. The primary outcome was physical functioning (Oswestry Disability Index, range 0-100). Secondary outcomes included pain intensity, fear-avoidance beliefs, and self-reported adherence. Measurements were taken at baseline and at the 3-month follow-up.

Results

Both the stratified blended physiotherapy group (104/208, 50%) and the face-to-face physiotherapy group (104/208, 50%) had improved clinically relevant and statistically significant physical functioning; however, there was no statistically significant or clinically relevant between-group difference (mean difference −1.96, 95% CI −4.47 to 0.55). For the secondary outcomes, stratified blended physiotherapy showed statistically significant between-group differences in fear-avoidance beliefs and self-reported adherence. In patients with a high risk of developing persistent LBP (13/208, 6.3%), stratified blended physiotherapy showed statistically significant between-group differences in physical functioning (mean difference −16.39, 95% CI −27.98 to −4.79) and several secondary outcomes.

Conclusions

The stratified blended physiotherapy intervention e-Exercise LBP is not more effective than face-to-face physiotherapy in patients with nonspecific LBP in improving physical functioning in the short term. For both stratified blended physiotherapy and face-to-face physiotherapy, within-group improvements were clinically relevant. To be able to decide whether e-Exercise LBP should be implemented in daily physiotherapy practice, future research should focus on the long-term cost-effectiveness and determine which patients benefit most from stratified blended physiotherapy.

Virtual reality exergame for supplementing multimodal pain therapy in older adults with chronic back pain: a randomized controlled pilot study

Immersive Virtual Reality (VR) with head-mounted displays (HMD) can be a promising tool for increasing adherence to exercise in older adults. However, there is little known about the effectiveness of an interactive multimodal therapy in VR for older chronic back pain (CBP) patients. The aim of the exploratory randomized controlled trial was to examine the preliminary effectiveness of a VR multimodal therapy for older adults with CBP in a laboratory setting over a period of four weeks. The intervention group (IG; n = 11) received a multimodal pain therapy in VR (movement therapy and psychoeducation) and the control group (CG; n = 11) received a conventional multimodal pain therapy (chair-based group exercises and psychoeducation in a group setting). Although the VR therapy (IG) did not reach the pain intensity reduction of the CG (IG: MD = 0.64, p = .535; CG: MD = 1.64, p = .07), both groups showed a reduction in pain intensity on the Numeric Rating Scale. The functional capacity in the IG improved from Visit 1, x ¯ = 73.11% to Visit 2, x ¯ = 81.82% (MD = 8.71%; p = .026). In the changes of fear avoidance beliefs and general physical and mental health, no significance was achieved in either group. Although the IG did not reach a significant pain intensity reduction compared to the CG, the results of the present study showed that a pain intensity reduction can be achieved with the current VR application.

Factors associated with exercise adherence to prevent or treat neck and low back pain: A systematic review

BACKGROUND

Much attention has been paid to the evaluation of the efficacy of exercise therapy or increasing physical activity with the aim to prevent or alleviate neck and low back pain. However, exercise adherence is necessary for the effective management of neck and low back pain.

OBJECTIVE

We aimed to systematically review randomized controlled trials and cohort studies to gain insights into the factors associated with adherence to exercise or physical activity programs to prevent or treat neck pain and low back pain.

METHOD

Publications were systematically searched from 1980-December 2019 in several databases. The following key words were used: neck pain or low back pain paired with exercise or physical activity and adherence or compliance. Relevant studies were retrieved and assessed for methodological quality by two independent reviewers. Quality of evidence was assessed and rated according to GRADE guidelines.

RESULTS

Nine randomized controlled trials and eight cohort studies were included in this review. Randomized controlled trials indicated moderate-quality evidence for the association between exercise adherence and self-efficacy. Cohort studies showed moderate-quality evidence for the association between exercise adherence and education level.

CONCLUSIONS

Literature investigating factors associated with exercise adherence to prevent or treat neck and low back pain was heterogeneous. Few factors were found to be associated with exercise adherence. More studies are needed before any firm conclusions can be reached.

Physical Therapists' Opinion of E-Health Treatment of Chronic Low Back Pain

(1) Background: Using new technologies to manage home exercise programmes is an approach that allows more patients to benefit from therapy. The objective of this study is to explore physical therapists’ opinions of the efficacy and disadvantages of implementing a web-based telerehabilitation programme for treating chronic low back pain (CLBP). (2) Methods: Nineteen physical therapists from academic and healthcare fields in both the public and private sector participated in the qualitative study. Texts extracted from a transcript of semi-structured, individual, in-depth interviews with each consenting participant were analysed to obtain the participants’ prevailing opinions. The interviews lasted approximately 40 min each. The participants’ responses were recorded. (3) Results: The results suggest that telerehabilitation can only be successful if patients become actively involved in their own treatment. However, exercise programmes for LBP are not always adapted to patient preferences. New technologies allow physical therapists to provide their patients with the follow-up and remote contact they demand, but long-term adherence to treatment stems from knowledge of the exercises and the correct techniques employed by the patients themselves. (4) Conclusions: Physical therapists treating patients with chronic non-specific low back pain believe that new technologies can provide highly effective means of reaching a greater number of patients and achieving significant savings in healthcare costs, despite the limitations of a telerehabilitation approach in developing an appropriate and effective patient-based physiotherapy programme.

Association between patient independence in performing an exercise program and adherence to home exercise program in people with chronic low back pain

BACKGROUND

A high percentage of patients with chronic low back pain (LBP) do not adequately adhere to home exercise programs. There is no information regarding a possible association between patient independence in performing an exercise program and adherence to this exercise program.

OBJECTIVE

To assess a possible association between patient independence in performing two different home exercise programs (treatment based on the Movement System Impairment-Based classification model (MSI) and treatment based on stretching and strengthening exercises for chronic LBP and adherence to those exercise programs.

DESIGN

This was a secondary analysis of a randomized controlled trial.

METHODS

The physical therapist assessed the patient's independence in performing the exercise program at the initial physical therapy sessions. Adherence was calculated during the 8-week treatment by the number of days performing the home exercise programs. Multivariate linear regression models were built to investigate whether patient independence in performing the home exercise program was associated with adherence to home exercise program for each treatment group adjusted for possible confounders (age, physical activity status, pain duration, pain intensity and disability at baseline).

RESULTS

We observed a clinically important association between patient independence in performing the home exercise and adherence to a treatment based on the MSI model group (ß = -15.6 days, 95%CI = -24.5 to -6.7, R² = 16%, p = 0.001).

CONCLUSIONS

People with chronic LBP adhered more to a home exercise program based on the MSI model when they are more independent in performing the exercise program.

Dose-response-relationship of stabilisation exercises in patients with chronic non-specific low back pain: a systematic review with meta-regression

Stabilization exercise (SE) is evident for the management of chronic non-specific low back pain (LBP). The optimal dose-response-relationship for the utmost treatment success is, thus, still unknown. The purpose is to systematically review the dose-response-relationship of stabilisation exercises on pain and disability in patients with chronic non-specific LBP. A systematic review with meta-regression was conducted (Pubmed, Web of Knowledge, Cochrane). Eligibility criteria were RCTs on patients with chronic non-specific LBP, written in English/German and adopting a longitudinal core-specific/stabilising/motor control exercise intervention with at least one outcome for pain intensity and/or disability. Meta-regressions (dependent variable = effect sizes (Cohens d) of the interventions (for pain and for disability), independent variable = training characteristics (duration, frequency, time per session)), and controlled for (low) study quality (PEDro) and (low) sample sizes (n) were conducted to reveal the optimal dose required for therapy success. From the 3,415 studies initially selected, 50 studies (n = 2,786 LBP patients) were included. N = 1,239 patients received SE. Training duration was 7.0 ± 3.3 weeks, training frequency was 3.1 ± 1.8 sessions per week with a mean training time of 44.6 ± 18.0 min per session. The meta-regressions' mean effect size was d = 1.80 (pain) and d = 1.70 (disability). Total R² was 0.445 and 0.17. Moderate quality evidence (R² = 0.231) revealed that a training duration of 20 to 30 min elicited the largest effect (both in pain and disability, logarithmic association). Low quality evidence (R² = 0.125) revealed that training 3 to 5 times per week led to the largest effect of SE in patients with chronic non-specific LBP (inverted U-shaped association). In patients with non-specific chronic LBP, stabilization exercise with a training frequency of 3 to 5 times per week (Grade C) and a training time of 20 to 30 min per session (Grade A) elicited the largest effect on pain and disability.

Predicting treatment adherence and outcome to outpatient multimodal rehabilitation in chronic low back pain

BACKGROUND

There is a growing need to identify patient pre-treatment characteristics that could predict adherence and outcome following specific interventions.

OBJECTIVE

To identify predictors of adherence and outcome to outpatient multimodal rehabilitation in chronic low back pain (CLBP).

METHODS

A total of 273 CLBP patients participated in an exercise-based rehabilitation program. Patients who completed ⩾ 70% of the treatment course were classified as adherent. Patients showing a post-treatment reduction of ⩾ 30% in Oswestry Disability Index (ODI) and Visual Analogue Scale (VAS) back pain intensity scores were assigned to the favorable outcome group.

RESULTS

Multivariate logistic regression revealed that higher age, higher ability to perform low-load activities, and higher degrees of kinesiophobia increased the odds to complete the rehabilitation program. By contrast, lower levels of education and back pain unrelated to poor posture increased the odds for non-adherence. Furthermore, a favorable outcome was predicted in case the cause for LBP was known, shorter symptom duration, no pain in the lower legs, no difficulties falling asleep, and short-term work absenteeism.

CONCLUSIONS

Assessment and consideration of patient pre-treatment characteristics is of great importance as they may enable therapists to identify patients with a good prognosis or at risk for non-responding to outpatient multimodal rehabilitation.

Effectiveness and cost-effectiveness of stratified blended physiotherapy in patients with non-specific low back pain: study protocol of a cluster randomized controlled trial

BACKGROUND

Patient education, advice on returning to normal activities and (home-based) exercise therapy are established treatment options for patients with non-specific low back pain (LBP). However, the effectiveness of physiotherapy interventions on physical functioning and prevention of recurrent events largely depends on patient self-management, adherence to prescribed (home-based) exercises and recommended physical activity behaviour. Therefore we have developed e-Exercise LBP, a blended intervention in which a smartphone application is integrated within face-to-face care. E-Exercise LBP aims to improve patient self-management skills and adherence to exercise and physical activity recommendations and consequently improve the effectiveness of physiotherapy on patients' physical functioning. The aim of this study is to investigate the short- (3 months) and long-term (12 and 24 months) effectiveness on physical functioning and cost-effectiveness of e-Exercise LBP in comparison to usual primary care physiotherapy in patients with LBP.

METHODS

This paper presents the protocol of a prospective, multicentre cluster randomized controlled trial. In total 208 patients with LBP pain were treated with either e-Exercise LBP or usual care physiotherapy. E-Exercise LBP is stratified based on the risk for developing persistent LBP. Physiotherapists are able to monitor and evaluate treatment progress between face-to-face sessions using patient input from the smartphone application in order to optimize physiotherapy care. The smartphone application contains video-supported self-management information, video-supported exercises and a goal-oriented physical activity module. The primary outcome is physical functioning at 12-months follow-up. Secondary outcomes include pain intensity, physical activity, adherence to prescribed (home-based) exercises and recommended physical activity behaviour, self-efficacy, patient activation and health-related quality of life. All measurements will be performed at baseline, 3, 12 and 24 months after inclusion. An economic evaluation will be performed from the societal and the healthcare perspective and will assess cost-effectiveness of e-Exercise LBP compared to usual physiotherapy at 12 and 24 months.

DISCUSSION

A multi-phase development and implementation process using the Center for eHealth Research Roadmap for the participatory development of eHealth was used for development and evaluation. The findings will provide evidence on the effectiveness of blended care for patients with LBP and help to enhance future implementation of blended physiotherapy.

Virtual reality distraction induces hypoalgesia in patients with chronic low back pain: a randomized controlled trial

Background

Attentional distraction from pain has been shown to be largely ineffective for obtaining a hypoalgesic effect in patients with chronic pain when compared to a control condition. It has been hypothesized that this may be due to the non-engaging types of distraction that have been used so far. Moreover, it is suggested that the hypoalgesic effects of distraction may be attenuated by pain-related cognitions and emotions, as they may increase the attention to pain.

Methods

In this randomized controlled trial, patients with chronic nonspecific low back pain in the intervention group (n = 42) performed a single exercise session with nonimmersive VR games, while those in the control group (n = 42) performed the same exercises without VR games. We investigated whether VR distraction had a hypoalgesic effect during and immediately after the exercises, and whether it reduced the time spent thinking of pain during the exercises. We further explored whether pain-related fear, pain catastrophizing and baseline pain intensity moderated the effects of VR distraction.

Results

VR distraction had a hypoalgesic effect during (Cohen’s d = 1.29) and immediately after (Cohen’s d = 0.85) the exercises, and it also reduced the time spent thinking of pain (Cohen’s d = 1.31). Preliminary exploratory analyses showed that pain-related fear, pain catastrophizing and baseline pain intensity did not moderate the effects of VR distraction.

Conclusions

Large effect sizes of VR distraction induced hypoalgesia were observed. This suggests that nonimmersive VR games can be used when it is deemed important to reduce the pain during exercises in patients with chronic nonspecific low back pain.

Do sociodemographic features, pain sensitivity or pain catastrophizing relate to clinic-based adherence to physiotherapy in people suffering from chronic spinal pain? Secondary analysis of a randomized clinical trial

PURPOSE

Examining whether socio-demographic variables, pain or functionality are related to the degree of clinic-based therapy adherence in patients suffering from nonspecific chronic spinal pain (nCSP).

DESIGN

Secondary analysis of a randomized clinical trial.

SETTING

University hospital of Ghent and Brussels.

METHODS

Dutch speakers, 18-65 years old, experiencing nCSP for at least 3 months. 120 participants were randomly allocated to two interventional groups, of which 94 completed all therapy sessions.

MAIN OUTCOME MEASURES

Degree of clinic-based adherence, defined as the amount of completed therapy sessions.

RESULTS

Demographic data (sex, age or education) were not significantly associated with adherence in the total sample or the neuroscience group. For the traditional physiotherapy group, educational level was associated with attendance of at least 50% of the therapy sessions. Regarding pain-, belief- and function-related measures, only the association between change in kinesiophobia and adherence was significant for the traditional physiotherapy group.

CONCLUSIONS

Factors related to therapy adherence in the total group or the neuroscience group could not be found. Educational level and change in kinesiophobia were however related to therapy adherence in the traditional physiotherapy group.

The Self-Efficacy for Home Exercise Programs Scale: Development and Psychometric Properties

BACKGROUND

The Self-Efficacy for Home Exercise Programs Scale (SEHEPS) was developed to help clinicians evaluate patients' self-efficacy for performing prescribed home exercise programs. Prior to clinical adoption, the scale's psychometric properties need to be examined.

OBJECTIVE

To determine the psychometric properties of the SEHEPS.

METHODS

Eighty-one patients (32 men, 49 women; mean ± SD age, 42 ± 17 years) with varying musculoskeletal conditions participated in this cohort study. Patients were given a home exercise program at the initial physical therapy visit and completed the SEHEPS and a modified Self-Efficacy for Exercise (SEE) scale. The SEHEPS is a 12-item patient-reported questionnaire designed to assess self-efficacy for prescribed home exercise. Patients rated their confidence on a 7-point scale that ranged from 0 (not confident) to 6 (very confident). Total scores ranged from 0 (low self-efficacy) to 72 (high self-efficacy). We assessed the internal consistency of the SEHEPS using Cronbach's alpha and its test-retest reliability using an intraclass correlation coefficient. Convergent validity between the SEHEPS and SEE scale was evaluated with a Spearman correlation.

RESULTS

High internal consistency (α = .96) and good test-retest reliability (intraclass correlation coefficient = 0.88; SEM, 4; minimal detectable change at the 95% confidence level, 12) were demonstrated. The SEHEPS was strongly correlated with the SEE scale (ρ = 0.83, P<.01), indicating strong convergent validity.

CONCLUSION

The SEHEPS demonstrates excellent internal consistency and convergent validity with the SEE scale. Overall, the SEHEPS is a clinically useful tool to evaluate a patient's self-efficacy in home-based musculoskeletal exercise programs. This scale can be used prior to prescribing a home exercise program for patients with musculoskeletal conditions.

The effectiveness of a simplified core stabilization program (TRICCS-Trivandrum Community-based Core Stabilisation) for community-based intervention in chronic non-specific low back pain

BACKGROUND

Chronic low back pain is a common public health problem all over the world. Conservative therapy is prescribed as the initial treatment strategy in chronic low back pain. The cornerstone of conservatism in back care is core muscle strengthening. However, exercises prescribed for the purpose are manifold and some are not easily done by patients in Asian countries. We developed an easy to adhere exercise protocol for core stabilization and tested its effectiveness in south Indian population.

METHODS

Prospective study of 73 patients with chronic low back pain (CLBP) who were subjected to Trivandrum Community-based Core Stabilisation protocol of treatment. The enrolled patients underwent initial Oswestry Disability Index (ODI) evaluation and Keele Start Back (KSB) questionnaire before starting the protocol. Back education was given, and the patient started on stratified exercise protocol. ODI assessment was done weekly. The trend in ODI changes and the factors determining them were assessed using ANOVA. The correlation of quantitative variables like age, initial ODI score, and KSB score with the rate of reduction of ODI was assessed using Pearson's correlation. Cross-tabulations were done using the chi-square test. Parametric tests were used throughout the analysis as the quantitative study variables found to be linear. Multiple linear regression (for the quantitative outcome) and binary logistic regression (for the dichotomous outcome) were performed.

RESULTS

Mean (SD) of ODI score has reduced significantly from 43.4 (16.6) to 24.6 (17.1) over the period of 6 weeks (p value < 0.001). The trend in reduction of ODI scores was significantly more in KSB score less than or equal to 3 compared to KSB more than 3 even after adjusting for the general trend of decreasing ODI score over time. The reduction in ODI scores appeared to be low for advancing age (p = 0.468) and higher KSB scores (p = 0.001).

CONCLUSION

The TRICCS protocol is effective in a community-based approach in achieving satisfactory outcomes in CLBP in a period of 6 weeks. Patients with high KSB scores may require cognitive intervention also.

The knowledge of low back pain management between physical therapists and family practice physicians

Objectives: The purpose of this study was to compare knowledge in managing patients with low back pain (LBP) between physical therapists and family practice physicians. Methods: Seventy-three physical therapists and 30 family practice physicians completed standardized examinations assessing knowledge, attitudes, the usefulness of clinical practice guidelines, and management strategies for patients with LBP. Beliefs of physical therapists and family practice physicians about LBP were compared using relative risks and independent t-tests. Results: Scores related to knowledge, attitudes, and the usefulness of clinical practice guidelines were generally similar between the groups. In addition, there was no difference between the groups for knowledge regarding optimal management strategies for patients with LBP. However, physical therapists were less likely to have difficulty assessing motivation levels of patients with LBP compared to family practice physicians (64.6% vs 26.7%; relative risk: 2.41 [95% confidence interval: 1.30-4.48] and physical therapists were less likely to agree that interventions by health care providers have little positive effect on the natural history of acute LBP (17.8% vs. 50.0%; relative risk: 0.36 [95% confidence interval: 0.19-0.66]). Discussion: The results of this study may have implications for third-party payers and health care administrators regarding the utilization of physical therapists in the management of patients with LBP in expanded scopes of practice, including direct access and potential placement in primary care clinics.

Measurements of self-efficacy in musculoskeletal rehabilitation: A systematic review

OBJECTIVES

Low self-efficacy is a barrier to rehabilitation adherence. Before an intervention can be implemented to improve self-efficacy, assessment is required. It is currently unknown if a standard measure of self-efficacy has been used to assess this in patients with musculoskeletal conditions, specifically for home exercise programmes (HEPs). The aim of the present study was to determine which self-efficacy scales are being used in conjunction with exercise adherence, identify if any scale has been developed to evaluate self-efficacy for HEPs and evaluate their psychometric properties.

METHODS

Data sources included CINAHL, MEDLINE, Pubmed, PsycInfo, and Sport Discus. Studies had to include patients suffering from a musculoskeletal injury, pain or disorder; a measure of rehabilitation adherence; and patient's self-efficacy. The study population, self-efficacy measurement used, study quality as identified with the Modified Downs and Black checklist, results pertaining to self-efficacy, and level of evidence were extracted. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed and 29 articles were included.

RESULTS

A total of 14 scales assessing self-efficacy were identified but no scale to assess self-efficacy for HEPs was found. Many scales report internal consistency but lack test-retest reliability and validity.

CONCLUSIONS

The scales identified were specific to condition or tasks, and not applicable for all musculoskeletal patient populations. It is important, both for use in the clinic and for research, that outcome measures used are reliable and valid. Unfortunately, no scale was found to assess self-efficacy for HEPs, which is problematic as self-efficacy is task specific. As HEPs are essential to rehabilitation, there should be a scale designed specifically to assess self-efficacy for this task.

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.

Outcome measures for adherence to home exercises among patients with chronic low back pain: a systematic review

[Purpose] The aim of this study was to investigate what outcome measures are reliable in the evaluation of adherence to home exercises among patients with chronic low back pain. [Methods] A systematic review on articles related to adherence to home exercises for patients with chronic low back pain was conducted, and outcome measures and psychometric properties were extracted and evaluated in terms of validity and reliability. [Results] A total of 4,583 articles were identified, and eight articles were finally included after screening. The identified outcome measures were self-reported frequency, duration and intensity of home exercises and Treatment Self-Regulation Questionnaire results. Although the internal consistency and criterion validity of the Treatment Self-Regulation Questionnaire results have been proven in the literature, none of the included articles validated the self-reported frequency, duration, and intensity of the home exercises. [Conclusion] Only the Treatment Self-Regulation Questionnaire results were found to be a reliable measure, and further research to validate self-reported outcome measures is required.

Serious Gaming to Support Exercise Therapy for Patients with Chronic Nonspecific Low Back Pain: A Feasibility Study

OBJECTIVE

To investigate the feasibility of a functional exercise program supported by serious gaming for patients with chronic nonspecific low back pain (LBP).

METHODS

Ten patients with chronic nonspecific LBP and an underlying motor control impairment were recruited. Subjects performed a partially supervised exercise program (36 sessions, 18 weeks) that included 30 minutes of general conditioning and 90 minutes of individually tailored functional motor control exercises (MCEs). Serious games (SGs) were used to (1) improve thoracolumbar dissociation and (2) to provide postural feedback during functional MCEs. The SGs were also available at home.

RESULTS

Treatment satisfaction and the scores on the credibility/expectancy questionnaire were good and did not change throughout the intervention. Patients remained motivated throughout the rehabilitation program and no serious adverse events were reported. Overall, participants indicated that the SGs helped them to perform the home exercises more correctly, and as a consequence, they felt more confident doing them. However, the time needed to set up the games was a barrier for home use and participants would have found it useful to receive postural feedback during daily life activities.

CONCLUSIONS

It is feasible to support a functional exercise program with SGs for patients with chronic nonspecific LBP, both in a supervised and a home environment. Time-efficiency and the integration of SGs in daily life activities are challenges that need to be addressed in the future.

Comparison of Lower Limb and Back Exercises for Runners with Chronic Low Back Pain

INTRODUCTION

This single-blind randomized trial was conducted to compare the treatment effect of lower limb (LL) exercises versus conventional lumbar extensor (LE) and lumbar stabilization (LS) exercises in recreational runners with chronic low back pain (cLBP), because there is currently no specific protocol for managing runners with cLBP.

METHODS

Eighty-four recreational runners with cLBP were allocated to three exercise groups (LL, LE, LS) for an 8-wk intervention. Outcome measures included self-rated pain and running capability, LL strength, back muscle function, and running gait. Participants were assessed at preintervention, mid-intervention, and end-intervention; selected outcomes also followed up at 3 and 6 months. Generalized estimating equation was adopted to examine group-time interaction.

RESULTS

The LL group improved 0.949 points per time point in Patient-Specific Functional Scale (P < 0.001), which was higher than the LE (B = -0.198, P = 0.001) and LS groups (B = -0.263, P < 0.001). All three groups improved on average 0.746 points per time point in Numeric Pain Rating Scale for running-induced pain (P < 0.001). Knee extension strength increased 0.260 N·m·kg per time point (P < 0.001) in the LL group, which was higher than the LE (B = -0.220, P < 0.001) and LS groups (B = -0.206, P < 0.001). The LL group also showed a greater increase in running step length (2.464 cm per time point, P = 0.001) compared with LS group (B = -2.213, P = 0.013). All three groups improved similarly in back muscle function.

CONCLUSION

LL exercise therapy could be a new option for cLPB management given its superior effects in improving running capability, knee extension strength, and running gait.

Movement System Impairment-Based Classification Treatment Versus General Exercises for Chronic Low Back Pain: Randomized Controlled Trial

Background

Treatment for chronic low back pain (LBP) includes different forms of exercises, that to date have resulted in only small to moderate treatment effects. To enhance the treatment effects, different classification systems have been developed to classify people with LBP into more homogeneous subgroups leading to specific treatments for each subgroup.

Objective

The purpose of this study was to compare the efficacy of a treatment based on the Movement System Impairment (MSI) model with a treatment consisting of symptom-guided stretching and strengthening exercises in people with chronic LBP.

Design

The study was a 2-arm, prospectively registered, randomized controlled trial with a blinded assessor.

Setting

The study setting was a university physical therapy clinic in Brazil.

Patients

A total of 148 participants with chronic LBP participated in the study.

Interventions

Participants were randomly allocated to an 8-week treatment of either treatment based on the MSI-based classification system or symptom-guided stretching and strengthening exercises.

Measurements

Measures of pain intensity, disability, and global impression of recovery were obtained by a blinded assessor at baseline and at follow-up appointments at 2, 4, and 6 months after randomization.

Results

There were no significant between-group differences for the primary outcomes of pain intensity at 2 months (mean difference = 0.05, 95% CI = –0.90 to 0.80) and disability at 2 months (mean difference = 0.00, 95% CI = –1.55 to 1.56). There also were no statistically significant differences between treatment groups for any of the secondary outcome measures.

Limitations

Participants and physical therapists were not masked.

Conclusions

People with chronic LBP had similar improvements in pain, disability, and global impression of recovery with treatment consisting of symptom-guided stretching and strengthening exercises and treatment based on the MSI model.

Innovative exercise device for the abdominal trunk muscles: An early validation study

BACKGROUND

Exercise is one of the few treatments that provide significant improvements in chronic low back pain (CLBP). We developed an innovative exercise device for abdominal trunk muscles. This device can be used in a sitting or standing position and contains a built-in system to measure abdominal trunk muscle strength. We examined whether subjects can adequately use the device to perform the exercises and measure their abdominal trunk muscle strength.

METHODS

We collected data on the body height, body weight, body mass index, and girth of 30 healthy male volunteers, and measured their grip power and trunk extensor muscle strength using a dynamometer. The volunteers performed a sit-up test as an indicator of trunk flexor muscle strength, and we measured their abdominal muscle strength using the device. We then evaluated the correlations between abdominal trunk muscle strength and anthropometric parameters as well as the strength of other muscles. In subsequent tests, 5 of the 30 subjects participated in two positron emission tomography (PET) series consisting of examinations after a resting period (control study) and during exercise (exercise study). For the exercise study, the subjects performed 2 sets of exercises for 20 minutes using the device before and after an injection of 18F-fluorodeoxyglucose (FDG). PET-computed tomography images were obtained 60 minutes after FDG injection in each study. We compared the skeletal muscle metabolism of the participants in both studies using the standardized uptake value.

RESULTS

The muscle strength measured by the device and the 30-second sit-up frequency were correlated. FDG accumulation within the diaphragm and abdominal rectus muscles was significantly higher in the exercise study.

CONCLUSION

Our innovative exercise device facilitates a coordinated contraction of the abdominal trunk muscles at the anterior aspect and the roof of the core, and enables subjects to measure the strength of these muscles.

Pelvic floor muscle contraction and abdominal hollowing during walking can selectively activate local trunk stabilizing muscles

BACKGROUND

Trunk muscle exercises are widely performed, and many studies have been performed to examine their effects on low back pains. However, the effect of trunk muscles activations during walking with pelvic floor muscle contraction (PFMC) and abdominal hollowing (AH) has not been clarified.

OBJECT

To investigate whether walking with PFMC and AH is more effective for promoting local trunk muscle activation than walking without PFMC and AH.

METHODS

Twenty healthy men (28.9 ± 3.14 years, 177.2 ± 4.25 cm, 72.1 ± 6.39 kg, body mass index 22.78 ± 2.38 kg/m2) were participated in this study. Surface electrodes were attached over the multifidus (MF), lumbar erector spinae (LES), thoracic erector spinae (TES), transverse abdominus-internal oblique abdominals (TrA-IO), external oblique abdominals (EO), and rectus abdominus (RA). The amplitudes of electromyographic signals were measured during a normal walking with and without PFMC and AH.

RESULT

PFMC and AH while walking was found to result in significant bilateral increases in the normalized maximum voluntary contraction (MVC) of MFs and TrA-IOs (p< 0.05). Ratios of local muscle activity to global muscle activities were increased while performing PFMC and AH during normal walking. Bilateral TrA-IO/EO activity ratios were significantly increased by PFMC and AH (p< 0.05).

CONCLUSION

Performance of the PFMC and AH during walking resulted in significantly more recruitment of local trunk muscles. This study suggests that PFMC and AH during normal daily walking improves activation of muscles responsible for spinal dynamic stabilization and might be useful if integrated into low back disability and pain physical rehabilitation efforts.

The effectiveness of home-based exercise programs for low back pain patients

[Purpose] The purpose of this study was to investigate the effectiveness of home-based exercise programs for low back pain (LBP) patients. [Subjects and Methods] The study subjects were 49 volunteer chronic LBP patients. Home-based exercises that had been specifically modified for the individual patients were prescribed for a period of four weeks, and the volunteers were asked to return for a control evaluation at the end of this period. Exercise adherence and correct performance, pain intensity, disability, endurance, and flexibility were compared between pre- and post intervention, and correlations between exercise adherence and correct performance with, pain intensity score, endurance, disability, and flexibility were investigated. [Results] Twenty-eight patients (57.14%) did not return for the control evaluation. The mean age of the patients who participated in this control test was 43.24 ± 10.89 years. The adherence rate of the home exercise program was 54.10 ± 26.01%, and the correctly performed execises score was 2.7 ± 1.9. All of the parameters had improved at the final evaluation; however, there was no correlation among the parameters. [Conclusion] Clinicians should be aware of the patient’s adherence level when recommending home-based exercises, and should also realize that exercises might be performed inaccurately in an unsupervised environment.

The effect of individualized gradable stabilization exercises in patients with chronic low back pain: Case-control study

BACKGROUND

There is no evidence that one exercise program is better than another for rehabilitation of patients with chronic low back pain (CLBP).

OBJECTIVE

To identify the safety and efficacy of a gradable stabilization exercise protocol in patients with CLBP.

METHODS

This study is a retrospective cohort study with 65 patients. The exercise group received the gradable stabilization exercise protocol for 3 weeks over 6-8 visits, while the control group did not receive any exercise protocol. All subjects were evaluated with the visual analog scale (VAS), Oswestry Disability Index (ODI), Fear-Avoidance Belief Questionnaire (FABQ), the active sit-up test (AST), side support test (SST), and extensor endurance test (EET).

RESULTS

After gradable stabilization exercise, the exercise group showed significant improvement in VAS, FABQ-W, ODI, AST, SST and EET (p< 0.05). And the exercise group showed better improvement than the control group in VAS, FABQ-W, ODI, AST, SST and EET (p< 0.05). The rate of treatment success was 77.1% among patients assigned to the exercise group, as compared with 12.0% among those assigned to the control group.

CONCLUSIONS

This study showed that the gradable stabilization exercise protocol has the possibility to improve clinical and physical findings.

Motor control exercise for acute non-specific low back pain

BACKGROUND

Motor control exercise (MCE) is used by healthcare professionals worldwide as a common treatment for low back pain (LBP). However, the effectiveness of this intervention for acute LBP remains unclear.

OBJECTIVES

To evaluate the effectiveness of MCE for patients with acute non-specific LBP.

SEARCH METHODS

We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), four other databases and two trial registers from their inception to April 2015, tracked citations and searched reference lists. We placed no limitations on language nor on publication status.

SELECTION CRITERIA

We included only randomised controlled trials (RCTs) examining the effectiveness of MCE for patients with acute non-specific LBP. We considered trials comparing MCE versus no treatment, versus another type of treatment or added as a supplement to other interventions. Primary outcomes were pain intensity and disability. Secondary outcomes were function, quality of life and recurrence.

DATA COLLECTION AND ANALYSIS

Two review authors screened for potentially eligible studies, assessed risk of bias and extracted data. A third independent review author resolved disagreements. We examined MCE in the following comparisons: (1) MCE versus spinal manipulative therapy; (2) MCE versus other exercises; and (3) MCE as a supplement to medical management. We used the GRADE (Grades of Recommendation, Assessment, Development and Evaluation) approach to assess the quality of evidence. For missing or unclear information, we contacted study authors. We considered the following follow-up intervals: short term (less than three months after randomisation); intermediate term (at least three months but within 12 months after randomisation); and long term (12 months or longer after randomisation).

MAIN RESULTS

We included three trials in this review (n = 197 participants). Study sample sizes ranged from 33 to 123 participants. Low-quality evidence indicates no clinically important differences between MCE and spinal manipulative therapy for pain at short term and for disability at short term and long term. Low-quality evidence also suggests no clinically important differences between MCE and other forms of exercise for pain at short or intermediate term and for disability at intermediate term or long term follow-up. Moderate-quality evidence shows no clinically important differences between MCE and other forms of exercise for disability at short term follow-up. Finally, very low-quality evidence indicates that addition of MCE to medical management does not provide clinically important improvement for pain or disability at short term follow-up. For recurrence at one year, very low-quality evidence suggests that MCE and medical management decrease the risk of recurrence by 64% compared with medical management alone.

AUTHORS' CONCLUSIONS

We identified only three small trials that also evaluated different comparisons; therefore, no firm conclusions can be drawn on the effectiveness of MCE for acute LBP. Evidence of very low to moderate quality indicates that MCE showed no benefit over spinal manipulative therapy, other forms of exercise or medical treatment in decreasing pain and disability among patients with acute and subacute low back pain. Whether MCE can prevent recurrences of LBP remains uncertain.

Motor control exercise for chronic non-specific low-back pain

BACKGROUND

Non-specific low back pain (LBP) is a common condition. It is reported to be a major health and socioeconomic problem associated with work absenteeism, disability and high costs for patients and society. Exercise is a modestly effective treatment for chronic LBP. However, current evidence suggests that no single form of exercise is superior to another. Among the most commonly used exercise interventions is motor control exercise (MCE). MCE intervention focuses on the activation of the deep trunk muscles and targets the restoration of control and co-ordination of these muscles, progressing to more complex and functional tasks integrating the activation of deep and global trunk muscles. While there are previous systematic reviews of the effectiveness of MCE, recently published trials justify an updated systematic review.

OBJECTIVES

To evaluate the effectiveness of MCE in patients with chronic non-specific LBP.

SEARCH METHODS

We conducted electronic searches in CENTRAL, MEDLINE, EMBASE, five other databases and two trials registers from their inception up to April 2015. We also performed citation tracking and searched the reference lists of reviews and eligible trials.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that examined the effectiveness of MCE in patients with chronic non-specific LBP. We included trials comparing MCE with no treatment, another treatment or that added MCE as a supplement to other interventions. Primary outcomes were pain intensity and disability. We considered function, quality of life, return to work or recurrence as secondary outcomes. All outcomes must have been measured with a valid and reliable instrument.

DATA COLLECTION AND ANALYSIS

Two independent review authors screened the search results, assessed risk of bias and extracted the data. A third independent review author resolved any disagreement. We assessed risk of bias using the Cochrane Back and Neck (CBN) Review Group expanded 12-item criteria (Furlan 2009). We extracted mean scores, standard deviations and sample sizes from the included trials, and if this information was not provided we calculated or estimated them using methods recommended in the Cochrane Handbook. We also contacted the authors of the trials for any missing or unclear information. We considered the following time points: short-term (less than three months after randomisation); intermediate (at least three months but less than 12 months after randomisation); and long-term (12 months or more after randomisation) follow-up. We assessed heterogeneity by visual inspection of the forest plots, and by calculating the Chi(2) test and the I(2) statistic. We combined results in a meta-analysis expressed as mean difference (MD) and 95% confidence interval (CI). We assessed the overall quality of the evidence using the GRADE approach.

MAIN RESULTS

We included 29 trials (n = 2431) in this review. The study sample sizes ranged from 20 to 323 participants. We considered a total of 76.6% of the included trials to have a low risk of bias, representing 86% of all participants. There is low to high quality evidence that MCE is not clinically more effective than other exercises for all follow-up periods and outcomes tested. When compared with minimal intervention, there is low to moderate quality evidence that MCE is effective for improving pain at short, intermediate and long-term follow-up with medium effect sizes (long-term, MD -12.97; 95% CI -18.51 to -7.42). There was also a clinically important difference for the outcomes function and global impression of recovery compared with minimal intervention. There is moderate to high quality evidence that there is no clinically important difference between MCE and manual therapy for all follow-up periods and outcomes tested. Finally, there is very low to low quality evidence that MCE is clinically more effective than exercise and electrophysical agents (EPA) for pain, disability, global impression of recovery and quality of life with medium to large effect sizes (pain at short term, MD -30.18; 95% CI -35.32 to -25.05). Minor or no adverse events were reported in the included trials.

AUTHORS' CONCLUSIONS

There is very low to moderate quality evidence that MCE has a clinically important effect compared with a minimal intervention for chronic low back pain. There is very low to low quality evidence that MCE has a clinically important effect compared with exercise plus EPA. There is moderate to high quality evidence that MCE provides similar outcomes to manual therapies and low to moderate quality evidence that it provides similar outcomes to other forms of exercises. Given the evidence that MCE is not superior to other forms of exercise, the choice of exercise for chronic LBP should probably depend on patient or therapist preferences, therapist training, costs and safety.

Adherence to home exercises in non-specific low back pain. A randomised controlled pilot trial

Specific exercises for the improvement of movement control of the lumbopelvic region are well-established for patients with non-specific low back pain (NSLBP) and movement control impairment (MCI). However, a lack of adherence to home exercise regimens is often observed. The aim of the study was to explore the differences in home exercise (HE) adherence between patients who perform conventional exercises and those who exercise with Augmented Feedback (AF). Twenty patients with NSLBP and MCI were randomly allocated into two groups. The physiotherapy group (PT group) completed conventional exercises, and the AF group exercised with an AF system that was designed for use in therapy settings. The main outcome measure was self-reported adherence to the home exercise regimen. There was no significant difference in HE duration between the groups (W = 64, p = 0.315). The AF group exercised for a median of 9 min and 4 s (IQR = 3'59"), and the PT group exercised for 4 min and 19 s (IQR = 8'30"). Exercising with AF led to HE times that were similar to those of conventional exercise, and AF might be used as an alternative therapy method for home exercise.

Comparison of cross sectional area and fat infiltration of the epaxial muscles in dogs with and without spinal cord compression

This study investigated the cross sectional area (CSA) and fat infiltration of the epaxial muscles in Dachshunds with compressive spinal cord lesions due to intervertebral disc herniation (IVDH) and in dogs with non-compressive spinal cord lesions with fibrocartilaginous embolism (FCE). The CSA and fat infiltration of the multifidi and longissimus dorsi muscles were determined from T1 weighted magnetic resonance images. Difference in CSA and fat infiltration between the lesion- and non-lesion side in the Dachshunds was assessed using mixed model analysis. Difference in CSA and fat infiltration between Dachshunds and FCE dogs was analysed with independent sample t-tests. There was no difference in CSA or fat infiltration between sides in the Dachshunds. FCE dogs had greater CSA (multifidus P = 0.036, longissimus P < 0.001) and less fat infiltration compared to Dachshunds (longissimus P = 0.017). Duration of neurological deficits, age, body size and conformation are likely to have influenced the difference between the groups.

Reversal time of postprandial changes of the thickness of abdominal muscles employing ultrasound measurements

OBJECTIVES

Low thickness of Transversus Abdominis, Internal Oblique and External Oblique muscles may play a role in development of low back pain. Ultrasonography is increasingly utilized to measure the thickness of these muscles. Prandial state has recently been proposed as a confounding factor in such measurements. We aimed to compare the reversal time of the postprandial thickness of these muscles with preprandial values. The measurement errors of ultrasonographic values were also assessed in both immediate preprandial and postprandial states.

DESIGN

Interventional cross-sectional study.

METHODS

The ultrasonographic thickness of lateral abdominal muscles was measured at rest and during abdominal drawing-in maneuver in 20 healthy participants before and after consumption of a specific meal. Postprandial ultrasound measurements continued every 15 min until their thickness reached 95% of their preprandial values.

RESULTS

There was a statistically significant reduction in postprandial thickness of these muscles (all p-values <0.001 on both sides). The reversal times were 1.5, 1.3 and 1.2 h for Transversus Abdominis, Internal Oblique, and External Oblique muscles, respectively. Standard Error of Measurement and Smallest Detectable Change were in the range of 0.007-0.013 mm and 0.020-0.035 mm, respectively.

CONCLUSIONS

To limit the effects of prandial state on the sonographic thickness of lateral abdominal muscles, we recommend measuring these values at least 1.5-2 h after food consumption. For the future studies, controlling the participants according to their prandial state is recommended.

A systematic review of measures of self-reported adherence to unsupervised home-based rehabilitation exercise programmes, and their psychometric properties

BACKGROUND

Adherence is an important factor contributing to the effectiveness of exercise-based rehabilitation. However, there appears to be a lack of reliable, validated measures to assess self-reported adherence to prescribed but unsupervised home-based rehabilitation exercises.

OBJECTIVES

A systematic review was conducted to establish what measures were available and to evaluate their psychometric properties.

DATA SOURCES

MEDLINE, EMBASE, PsycINFO CINAHL (June 2013) and the Cochrane library were searched (September 2013). Reference lists from articles meeting the inclusion criteria were checked to ensure all relevant papers were included.

STUDY SELECTION

To be included articles had to be available in English; use a self-report measure of adherence in relation to a prescribed but unsupervised home-based exercise or physical rehabilitation programme; involve participants over the age of 18. All health conditions and clinical populations were included.

DATA EXTRACTION

Descriptive data reported were collated on a data extraction sheet. The measures were evaluated in terms of eight psychometric quality criteria.

RESULTS

58 studies were included, reporting 61 different measures including 29 questionnaires, 29 logs, two visual analogue scales and one tally counter. Only two measures scored positively for one psychometric property (content validity). The majority of measures had no reported validity or reliability testing.

CONCLUSIONS

The results expose a gap in the literature for well-developed measures that capture self-reported adherence to prescribed but unsupervised home-based rehabilitation exercises.

Restricted hip mobility: clinical suggestions for self-mobilization and muscle re-education

Restricted hip mobility has shown strong correlation with various pathologies of the hip, lumbar spine and lower extremity. Restricted mobility can consequently have deleterious effects not only at the involved joint but throughout the entire kinetic chain. Promising findings are suggesting benefit with skilled joint mobilization intervention for clients with various hip pathologies. Supervised home program intervention, while lacking specifically for the hip joint, are demonstrating promising results in other regions of the body. Application of an accompanying home program for the purpose of complementing skilled, in clinic intervention is advisable for those clients that respond favorably to such methodology.

Health-related behavior, profile of health locus of control and acceptance of illness in patients suffering from chronic somatic diseases

PURPOSE

The purpose of the study was to determine health-related behaviors, profile of health locus of control (HLC), and to assess the relationships between these constructs among patients suffering from chronic somatic diseases.

MATERIAL AND METHODS

Three-hundred adult patients suffering from various chronic diseases participated in the study. The patients' mean age was 54.6 years (SD = 17.57).

RESULTS

No statistically significant differences were found between the different clinical groups in health-related behavior, acceptance of illness, internal HLC or chance HLC. Patients with neurologic conditions showed slightly lower powerful others HLC than did some other clinical groups. Health-related behavior was significantly positively related to all three categories of HLC, with most prominent associations observed with powerful others HLC. Only one type of health-related behavior--preventive behavior--correlated significantly and negatively with acceptance of illness. Differences in the frequency of health-related behavior were also found due to gender (women showing more healthy nutritional habits than men), age (older subjects showing more frequent health-promoting behavior), education (higher education was associated with less frequent health-promoting behavior) and marital status (widowed subjects reporting more frequent health-promoting behavior).

CONCLUSIONS

Health-related behavior in patients with chronic diseases seems to be unrelated to a specific diagnosis; however it shows associations with both internal and external HLC. Sociodemographic factors are also crucial factors determining frequency of health-related behavior in such patients.
