Exercise for the Prevention of Low Back Pain: Systematic Review and Meta-Analysis of Controlled Trials

Effectiveness of exercise programs to reduce low back pain among nurses and nursing assistants: A systematic review and meta-analysis

INTRODUCTION

Nurses have a high prevalence of low back pain due to ergonomic hazards in healthcare workplaces. While exercise programs have been suggested as an intervention strategy, the effectiveness of low back pain programs has been inconsistent in the research literature. The purpose of study is to determine the effect of exercise programs to reduce low back pain among nursing staff.

METHODS

A systematic review and meta-analysis was conducted with five databases and systematically searched. Following the PRISMA guidelines, included studies evaluated low back pain relief among nurses or nursing assistants and described the exercise program. Two reviewers independently appraised, extracted, and synthesized all available studies. The study protocol was registered in PROSPERO (CRD42022359511).

RESULTS

A total of 296 articles with 1,355 nursing staff from nine countries were obtained. Nine randomized controlled trials with a moderate to low risk of bias quality were included. Exercise programs had a small but significant effect on low back pain of nursing staff (SMD = -0.48; 95% CI = -0.76 to -0.19; p = 0.03, I2 = 62%, p = 0.001). A subgroup analysis of nurses and nursing assistants showed moderate and small effects, respectively (I2 = 0% p < 0.0001, SMD -0.73 CI 95% [-0.97 to -0.48], p = 0.76, and I2 = 0% p = 0.002, SMD -0.23 CI 95% [-0.38 to -0.08], p < 0.88). Exercise for back and trunk exhibited a moderate effect on low back pain (SMD -0.56 CI 95% [-0.86 to -0.25], p = 0.01, I2 = 66%, p < 0.0004). A subgroup analysis comparing age, under 40 years old revealed a moderate effect size (SMD = -0.59; 95% CI = -0.83to -0.35; p = 0.06; I2 = 64%, p < 0.0001).

CONCLUSIONS

Exercise programs are an effective treatment to reduce low back pain in nurses and nursing assistants, especially among younger staff.

PRACTICAL APPLICATION

Back and trunk exercise programs should be recommended for nursing staff with low back pain.

Low back pain prevention behaviors and beliefs among the Polish population in a cross-sectional survey

Background

Low back pain (LBP) is one of the most common problems of public health and creates a burden globally. The aim was to assess the Polish population's back pain prevention behaviors and beliefs and to examine how these health behaviors and beliefs vary across sociodemographic factors and physical activity.

Methods

A cross-sectional survey was carried out among 208 randomly selected patients of the public general practitioner clinic. The differences in LBP-related beliefs and attitudes were determined due to participants' status of requiring or non-requiring LBP treatment.

Results

More than half of the respondents did not engage in behaviors that protect against back pain. Individuals with higher education levels and those who exercised at least once a week were significantly more likely to adopt behaviors to protect their backs. Less than half of the participants reported having a workplace that was adequately prepared to protect against back pain, and only 35.1% of the participants reported receiving instruction while taking up work on how to avoid back pain while working. According to respondents' opinions, preventive actions are necessary to protect against back pain. Inappropriate exercises and stress can be contributors to back pain, with these opinions reported more often by women and participants with higher education levels. Participants who received treatment for LBP showed a significantly higher expression of behaviors to protect against back pain compared to participants who did not require treatment. However, there were no significant differences in participants' beliefs about back pain prevention between the group requiring LBP treatment and the group not requiring LBP treatment.

Conclusion

The study provides valuable insights into the association between LBP treatment, back pain prevention behaviors, and beliefs, suggesting potential avenues for future research and intervention development. By addressing workplace ergonomics and promoting a culture of back health, it may be possible to reduce the burden of LBP in Poland.

Effects of Pain Neuroscience Education and Physiotherapy on Chronic Low Back Pain, Fear of Movement and Functional Status: A Randomised Pilot Study

Background: Chronic non-specific low back pain is a non-harmous condition often found in the general population. It is one of the most significant disabilities and needs different treatment modalities. This study investigates the effects of pain neuroscience education and physiotherapy on pain intensity, fear of movement and functional status in a Lithuanian cohort with non-specific low back pain. Methods: The study was performed at the primary health care unit in Kaunas, Lithuania. The key inclusion criterion was persistent non-specific low back pain longer than three months and which affects daily life functions. Thirty participants (mean 33.47, SD 4.38 years age, 70% women) were randomised into two training groups with and without pain neuroscience education (for a total of 60 min of teaching). Physiotherapy was performed twice per week during 45 min/session for a period of 10 weeks with exercises which strengthen, stabilize, and stretch the spinal cord muscles. Outcomes included pain intensity, kinesiophobia and disability and these were measured by self-scored questionnaires (numeric rating scale, Tampa scale for kinesiophobia-11, Oswestry disability index and the Roland-Morris questionnaire, respectively). Results: The results indicate that both groups improved in the measured outcomes, with the only difference between them being a better improvement in kinesiophobia in the group receiving physiotherapy and pain neuroscience education. Conclusions: The results of this study confirm that a relatively short intervention of pain neuroscience education enhances the effects of physiotherapy and should be implemented in clinical practice.

Societal beliefs about pain may be more balanced than previously thought. Results of the Guernsey pain survey

BACKGROUND

Musculoskeletal pain is multidimensional and associated with significant societal impact. Persistent or chronic pain is a public health priority. A step towards high-value care is a contemporary understanding of pain. While pain-related knowledge has been examined in specific conditions (e.g. neck pain) knowledge of the public's broader understanding regarding musculoskeletal pain per se, warrants investigation. This study examined the public's knowledge and beliefs regarding musculoskeletal pain and pain management.

METHODS

This observational cohort study was conducted in Guernsey (January 2019-February 2020). Participants (n = 1656; 76.0% female) completed an online questionnaire capturing: demographics, pain experience, work absenteeism, understanding of pain and pain management, multidimensional influences, physical activity, pain catastrophising and healthcare decision-making. Statements were deemed true/false/equivocal and mapped to biopsychosocial/biomedical/neutral perspectives based upon contemporary literature. Descriptive statistics were analysed for each statement. Participants' responses were examined for alignment to a contemporary viewpoint and themes within responses derived using a semi-quantitative approach modelled on direct content analysis. Comparisons between participants with/without pain were examined (χ2-squared/Wilcoxon Rank Sum test).

RESULTS

Within the cohort 83.6% reported currently experiencing pain. The overarching theme was perspectives that reflected both biomedical and contemporary, multidimensional understandings of pain. Sub-themes included uncertainty about pain persistence and evidence-based means to reduce recurrence, and reliance upon healthcare professionals for guiding decision-making. Compared to those with pain, those without had a greater belief that psychological interventions may help and lower pain catastrophising.

CONCLUSIONS

Participants' understanding of pain demonstrated both biomedical and multidimensional pain understanding consistent with elements of a contemporary understanding of pain.

Prevention of Work Absence Due to Back Pain: A Network Meta-Analysis

This paper reviewed the most effective strategies for preventing work absence due to back pain (BP) and BP episodes (the number of people reporting back pain). We searched randomized controlled trials (RCTs) of prevention strategies for BP from previous meta-analyses, PubMed, CENTRAL, and Embase and conducted a network meta-analysis. Thirteen RCTs (2033 participants) were included. Low- to high-quality evidence showed that exercise combined with ergonomics, education, back belts, and education combined with ergonomics did not prevent sickness absenteeism or BP episodes. There was moderate-quality evidence that exercise, especially resistance exercise, was the best prevention strategy to reduce the number of people reporting absenteeism due to BP (risk ratio [RR] = 0.10; 95% CI: 0.01 to 0.69). Moderate-quality evidence suggested that resistance and stretching exercises combined with education was the best prevention strategy to reduce pain (RR = 0.80; 95% CI: 0.67 to 0.96) and the number of absenteeism days for BP (standardized mean difference [SMD] = -0.39; 95% CI: -0.77 to -0.02). In conclusion, exercise, especially resistance and stretching exercises, and exercise combined with education were ranked as the best interventions to prevent sickness absenteeism and BP episodes.

Chronic disease clusters are associated with prolonged, bothersome, and multisite musculoskeletal pain: a population-based study on Northern Finns

BACKGROUND

Chronic diseases often accumulate with musculoskeletal (MSK) pain. However, less evidence is available on idiosyncratic patterns of chronic diseases and their relationships with the severity of MSK pain in general MSK pain populations.

MATERIAL AND METHODS

Questionnaire-based data on physician-diagnosed chronic diseases, MSK pain and its dimensions (frequency, intensity, bothersomeness, and the number of pain sites), and confounders were collected from the Northern Finland Birth Cohort 1966 at the age of 46. Latent Class Analysis (LCA) was used to identify chronic disease clusters among individuals who reported any MSK pain within the previous year (n = 6105). The associations between chronic disease clusters, pain dimensions, and severe MSK pain, which was defined as prolonged (over 30 d within the preceding year), bothersome (Numerical Rating Scale >5), and multisite (two or more pain sites) pain, were analyzed using logistic regression and general linear regression models, adjusted for sex and educational level (n for the full sample = 4768).

RESULTS

LCA resulted in three clusters: Metabolic (10.8% of the full sample), Psychiatric (2.9%), and Relatively Healthy (86.3%). Compared to the Relatively Healthy cluster, the Metabolic and Psychiatric clusters had higher odds for daily pain and higher mean pain intensity, bothersomeness, and the number of pain sites. Similarly, the odds for severe MSK pain were up to 75% (95% confidence interval: 44%-113%) and 155% (81%-259%) higher in the Metabolic and Psychiatric clusters, respectively, after adjustments for sex and educational level.

CONCLUSIONS

Distinct patterns of chronic disease accumulation can be identified in the general MSK pain population. It seems that mental and metabolic health are at interplay with severe MSK pain. These findings suggest a potential need to screen for psychiatric and metabolic entities of health when treating working-aged people with MSK pain.Key messagesThis large study on middle-aged people with musculoskeletal pain aimed to examine the idiosyncratic patterns of chronic diseases and their relationships with the severity of musculoskeletal pain. Latent class cluster analysis identified three chronic disease clusters: Psychiatric, Metabolic, and Relatively Healthy. People with accumulated mental (Psychiatric cluster) or metabolic diseases (Metabolic cluster) experienced more severe pain than people who were relatively healthy (Relatively Healthy cluster). These findings suggest a potential need to screen for psychiatric and metabolic entities of health when treating working-aged people with MSK pain.

Low Back Pain in Resident Doctors with Standardized Training in China: A Cross-Sectional Study

Background

Low back pain (LBP) is a prevalent occupational disease with high morbidity among healthcare workers. Since the implementation of standardized residency training in China in 2015, the training intensity has significantly increased, which may lead to a higher incidence of LBP. However, epidemiological studies on LBP among resident doctors with standardized training remain scarce.

Objective

To investigate the prevalence and associated factors of LBP among resident doctors with standardized training in a tertiary hospital in China.

Methods

A cross-sectional study was conducted using self-administered questionnaires to collect information on demographics, lifestyle factors, work-related factors, and LBP from 345 resident doctors. Descriptive statistics were used to analyze the prevalence of LBP. Logistic regression analysis was performed to identify factors associated with LBP.

Results

Among 345 participants, the 1-year prevalence of LBP was 75.9%. Multivariable analysis revealed that physical exercise, weekly working hours, and prolonged sitting were independent risk factors for LBP.

Conclusion

The prevalence of LBP among resident doctors was high. Promoting physical exercise, controlling working hours, and improving sitting posture may help prevent LBP. The study was limited by its cross-sectional design and self-reported data. Future studies should use longitudinal designs, objective measures, and larger and more representative samples to further explore the epidemiology and etiology of LBP among resident doctors with standardized training.

Acute Effects of Whole-Body Electrostimulation Combined with Stretching on Lower Back Pain

Data from recent studies suggest that whole-body electromyostimulation (WB-EMS) is a time-effective and tailored intervention for chronic lower back pain (CLBP). The aim of this non-randomized controlled study was to compare the efficacy of a WB-EMS training and the association between WB-EMS specific training with passive stretching (Well Back System, [WBS]) on CLBP. Forty patients with CLBP, 43-81 years old, were assigned to one of the two groups: WB-EMS (n=20) and WB-EMS+WBS (n=20). Both groups completed 12 sessions (8 weeks) of the WB-EMS protocol (2×20 minutes/week). The second group performed core-specific exercises with WB-EMS plus 6 extra stretching sessions (30 minutes each). Primary study endpoints were based on changes on the visual analogue scale (VAS) and changes on the Oswestry Low Back Disability Questionnaire (ODI). Secondary study endpoints were percentage changes of maximum trunk flexion (Sit & Reach, [SR]) and changes in consumption of painkillers. Both interventions significantly improved VAS, ODI, and SR values (p range: 0.04;<0.001). However, the change of VAS (-46% vs. -17%, p<0.001), ODI (-53% vs. -17%, p<0.001), and SR (+ 7 vs.+3 cm, p=0.001) were significantly higher in the WB-EMS+WBS group compared to the WB-EMS group. The working method with WB-EMS+WBS can be a joint-friendly, individualized form to decrease CLBP.

[Analysis of Sickness-Related Days of Absence among Soldiers of the German Armed Forces from 2008 to 2018 Part 1: Retrospective Analysis with Comparison to the Statutory Health Insurance System]

BACKGROUND

Sickness-related absences are of particular importance both in the German armed forces and in the civilian sector.

THE AIM OF THIS STUDY

was to analyze the incidence of sick leave among soldiers in comparison to the working population covered by the statutory health insurance (SHI) system.

METHOD

According to the systematics of the SHI, the key figures on incapacity to work in the period 2008-2018 are calculated in an age- and gender-standardized manner. Likewise, a list of the TOP 20 ICD-10 diagnoses in relation to incapacity to work was determined, and their average annual rates of change were calculated for trend analysis.

RESULTS

The annual rate of sick leave among soldiers was between 1.5 and 2.3%, which was lower than that of the SHI (3.1 to 5.0%). The duration of illness (sick days per case) among soldiers was between 9.0-15.6 days per year, compared with 10.9-14.4 days in the SHI system. The sickness frequency (cases per 100 persons) was lower among soldiers (48.2-75.0 cases) than in the SHI (96.8-131.0 cases). Most days of absence among soldiers were due to "respiratory infections (J06)" with 13.2%, "stress reactions (F43)" with 8.7%, "other infectious gastroenteritis and colitis (A09)" with 6.5%, "back pain (M54)" with 4.4% and "depressive episode (F32)" with 4.0% of all days of absence and were comparable to the values in SHI. "Depressive episode (F32)", "injuries (T14)", sreactions (F43)", "respiratory infections (J06)" and "pregnancy complaints (O26)" showed the highest rates of increase of+6.1% to+3.6% of days off work.

CONCLUSION

For the first time, it was possible to compare the sickness rate of soldiers with that of the general population in Germany, which may also provide indications for further measures for primary, secondary and tertiary prevention. The lower sickness rate among soldiers compared with the general population is mainly due to a lower incidence of illness, with a similar duration and pattern of illness, but with an overall upward trend. The ICD-10 diagnoses "Depressive episode (F32)," "injuries (T14)," "stress reactions (F43)," "acute upper respiratory tract infections (J06)" and "pregnancy complaints (O26)," which are increasing at an above-average rate in relation to the number of days absent, require further analysis. This approach seems promising, for example, to generate hypotheses and ideas for further improvement of health care.

A systematic review and meta-analysis of low back pain and its associated factors among school teachers in Africa

INTRODUCTION

Low back pain (LBP) is a key social, economic, and public health problem in the world. The impact of LBP is given less priority and is empirically unrepresented in low- and middle-income countries as a result of the focus on more pressing and life-threatening health issues, including infectious diseases. In Africa, the prevalence of LBP is irregular and increasing among schoolteachers on account of teaching activities performed under suboptimal working conditions. Therefore, the objective of this review was to estimate the pooled prevalence and associated factors of LBP among school teachers in Africa.

METHODS

This systematic review and meta-analysis was designed based on the PRISMA guidelines. A comprehensive systematic literature search focused on LBP in African school teachers was conducted using the PubMed/MEDLINE, CINAHL, and CABI databases, regardless of publication timelines, from October 20 to December 3, 2022. In addition, gray literature was searched using Google Scholar and Google Search. Data were extracted in Microsoft Excel by using the JBI data extraction checklist. The overall effect of LBP was estimated using a random effect model via DerSimonian-Laird weights. The pooled prevalence and odds ratio of associated factors with 95% CI were computed using STATA 14/SE software. The I² test and Egger's regression test were used to assess heterogeneity and publication bias, respectively.

RESULTS

A total of 585 articles were retrieved, and 11 eligible studies involving a total of 5,805 school teachers were included in this systematic review and meta-analysis. The overall estimated pooled prevalence of LBP in African school teachers was found to be 59.0% (95% CI: 52.0%-65.0%). Being female [POR: 1.53; 95% CI (1.19, 1.98)], being older [POR: 1.58; 95% CI (1.04, 2.40)], being physically inactive [POR: 1.92; 95% CI (1.04, 3.52)], having sleep problems [POR: 2.03; 95% CI (1.19, 3.44)] and having a history of injury [POR: 1.92; 95% CI (1.67, 2.21)] were factors significantly associated with LBP.

CONCLUSIONS

The pooled prevalence of LBP was high among school teachers in Africa compared to developed nations. Sex (female), older age, physical inactivity, sleep problems, and a history of previous injury were predictors of LBP. It is suggested that policymakers and administrators ought to gain awareness of LBP and its risk factors to put existing LBP preventive and control measures into action. Prophylactic management and therapeutic strategies for people with LBP should also be endorsed.

Labour's pain: strenuous subsistence work, mechanical wear-and-tear and musculoskeletal pain in a non-industrialized population

Musculoskeletal pain is the most debilitating human health condition. Neurophysiological pain mechanisms are highly conserved and promote somatic maintenance and learning to avoid future harm. However, some chronic pain might be more common owing to mismatches between modern lifestyles and traits that originally evolved under distinct premodern conditions. To inform assumptions about factors affecting chronic pain vulnerability prior to industrialization, we assess pain prevalence, perceived causes, and predictors among Tsimane forager-horticulturalists. Habitual subsistence work is the primary reported cause of pain throughout life for both sexes, and pain is more common with age, especially in the back, and for those with more musculoskeletal problems. Sex differences in pain are relatively weak, and we find no association between women's reproductive history and pain, contrary to the hypothesis that reproduction causes women's greater pain susceptibility. Age-standardized current pain prevalence is 1.7-8.2 times higher for Tsimane than other select populations, and Tsimane chronic pain prevalence is within the range of variation observed elsewhere. Chronic low back pain is not a 'mismatch disease' limited to post-industrialized populations. Hominin musculoskeletal changes supporting bipedalism probably imposed health costs, which, after millions of years of evolution, remain an epidemiological burden that may be exacerbated by modern conditions.

The effectiveness of hip interventions in patients with low-back pain: A systematic review and meta-analysis

BACKGROUND

Low-back pain (LBP) may be directly or indirectly related to impairments from the hip joint.

OBJECTIVE

To evaluate the effectiveness of hip interventions on pain and disability in patients with LBP in the short-, medium-, and long-term.

METHODS

PubMed, Cochrane Library, PEDro, Web of Science, and SCOPUS databases were searched in November 2022. Randomized controlled trials involving hip-targeted interventions compared to specific low back interventions in patients with LBP were selected. The outcomes were pain intensity and disability. The quality of the studies was assessed with the risk of bias tool. GRADE was used to rate the certainty of evidence. Meta-analyses were conducted using random effects models.

RESULTS

A total of 2581 studies were screened. Eight were included in the meta-analysis involving 508 patients with LBP. The results provided very low certainty that both hip strengthening and hip stretching improved pain (MD = -0.66; 95% CI -0.86, -0.48; I²:0%) (MD = -0.55; 95% CI -1.02, -0.08) and disability (SMD = -0.81; 95% CI -1.53, -0.10; I²: 80%) (SMD = -1.03; 95% CI -1.82, -0.25) in the short-term, respectively. No benefits were found in the medium- or long-term. The risk of bias, heterogeneity, and imprecision of the results downgraded the level of evidence.

CONCLUSIONS

Very low certainty evidence suggest a positive effect of hip strengthening in isolation or combined with specific low back exercise and hip stretching combined with specific low back exercise for decreasing pain intensity and disability in the short-term, in patients with LBP.

Effectiveness of Pain Neuroscience Education in Patients with Chronic Musculoskeletal Pain and Central Sensitization: A Systematic Review

OBJECTIVE

To collect the available evidence about the effectiveness of pain neuroscience education (PNE) on pain, disability, and psychosocial factors in patients with chronic musculoskeletal (MSK) pain and central sensitization (CS).

METHODS

A systematic review was conducted. Searches were performed on Pubmed, PEDro, and CINAHL, and only randomized controlled trials (RCTs) enrolling patients ≥18 years of age with chronic MSK pain due to CS were included. No meta-analysis was conducted, and qualitative analysis was realized.

RESULTS

15 RCTs were included. Findings were divided for diagnostic criteria (fibromyalgia-FM, chronic fatigue syndrome-CFS, low back pain-LBP, chronic spinal pain-CSP). PNE has been proposed as a single intervention or associated with other approaches, and different measures were used for the main outcomes considered. Conclusions, practice implication: PNE is effective in improving pain, disability, and psychosocial factors in patients with fibromyalgia, chronic low back pain (CLBP)-especially if associated with other therapeutic approaches-and also in patients with CFS and CSP. Overall, PNE seems to be more effective when proposed in one-to-one oral sessions and associated with reinforcement elements. However, specific eligibility criteria for chronic MSK pain due to CS are still lacking in most RCTs; therefore, for future research, it is mandatory to specify such criteria in primary studies.

Development and Validation of a Risk-Prediction Nomogram for Chronic Low Back Pain Using a National Health Examination Survey: A Cross-Sectional Study

BACKGROUND

Several prognostic factors have been reported for chronic low back pain (CLBP). However, there are no studies on the prediction of CLBP development in the general population using a risk prediction model. This cross-sectional study aimed to develop and validate a risk prediction model for CLBP development in the general population, and to create a nomogram that can help a person at risk of developing CLBP to receive appropriate counseling on risk modification.

METHODS

Data on CLBP development, demographics, socioeconomic history, and comorbid health conditions of the participants were obtained through a nationally representative health examination and survey from 2007 to 2009. Prediction models for CLBP development were derived from a health survey on a random sample of 80% of the data and validated in the remaining 20%. After developing the risk prediction model for CLBP, the model was incorporated into a nomogram.

RESULTS

Data for 17,038 participants were analyzed, including 2693 with CLBP and 14,345 without CLBP. The selected risk factors included age, sex, occupation, education level, mid-intensity physical activity, depressive symptoms, and comorbidities. This model had good predictive performance in the validation dataset (concordance statistic = 0.7569, Hosmer-Lemeshow chi-square statistic = 12.10, p = 0.278). Based on our model, the findings indicated no significant differences between the observed and predicted probabilities.

CONCLUSIONS

The risk prediction model presented by a nomogram, which is a score-based prediction system, can be incorporated into the clinical setting. Thus, our prediction model can help individuals at risk of developing CLBP to receive appropriate counseling on risk modification from primary physicians.

Adding a back care package to the primary healthcare; a community-based cluster-randomized trial

Introduction

The clinical course of LBP is complex and chronicity is more frequent than once thought. Moreover, insufficient evidence was found in support of any specific approach at the level of the general population.

Research question

This study aimed to evaluate the effectiveness of providing a back care package through the primary healthcare system in decreasing the rate of CLBP in the community.

Material and methods

Clusters were primary healthcare units with the covered population as participants. The intervention package comprised both exercise and educational content in the form of booklets. Data regarding LBP were collected at baseline, 3 and 9-month follow-ups. The LBP prevalence and the incidence of CLBP in the intervention group compared to the control group were analyzed using logistic regression through GEE.

Results

Eleven clusters were randomized including 3521 enrolled subjects. At 9 months, the intervention group showed a statistically significant decrease in both the prevalence and the incidence of CLBP, compared to the control group (OR ​= ​0.44; 95% CI ​= ​0.30-0.65; P ​< ​0.001 and OR ​= ​0.48; 95% CI ​= ​0.31-0.74; P ​< ​0.001, respectively).

Discussion and conclusion

The population-based intervention was effective in reducing the LBP prevalence and CLBP incidence. Our results suggest that preventing CLBP through a primary healthcare package including exercise and educational content is achievable.

Prevalence of chronic low back pain and its associated factors in the general population of South Korea: a cross-sectional study using the National Health and Nutrition Examination Surveys

BACKGROUND

Many factors associated with chronic low back pain (CLBP) have been proposed, including individual, psychosocial, and physical factors. However, these associated factors are still controversial.

PURPOSE

(1) To determine the prevalence of CLBP and (2) to analyze factors associated with CLBP in the general population using a nationally representative sample of South Koreans.

STUDY DESIGN

Cross-sectional study.

PATIENT SAMPLE

Data from versions IV-1, -2, and -3 of the Korea National Health and Nutrition Examination Survey (KNHANES), which were performed in 2007, 2008, and 2009, respectively (n = 24,871).

OUTCOME MEASURES

Multiple logistic regression analysis was performed to determine the association between several factors (age, gender, alcohol consumption, household income, education level, mid-intensity physical activity, depressive symptoms, vitamin D level, and comorbidities [stroke, ischemic heart disease, knee osteoarthritis, asthma, COPD, cancer history]) and CLBP.

METHODS

CLBP status was surveyed using a self-reported questionnaire. Demographic, socioeconomic status, comorbidities, and other factors were evaluated from health questionnaires, health and physical examinations, and laboratory tests. To analyze the association between these factors and CLBP, we used multiple logistic regression analysis.

RESULTS

Data from 17,038 participants were included in the final analysis, including 2,693 with CLBP and 14,345 without. The prevalence of CLBP was 15.8% in South Korean subjects, with a prevalence of 11.8% in men and 24.5% in women. After regression analysis, we found advanced age, female gender, mid-intensity physical activity, depressive symptoms, stroke, ischemic heart disease, knee arthritis, asthma, COPD, and cancer history were positively associated with CLBP. In contrast, alcohol consumption ≥ 1 drink per month, increased household income, higher education level, and vitamin D insufficiency were negatively associated with CLBP.

CONCLUSIONS

Our study showed that CLBP was most common in the elderly and women in the general South Korean population. Several individual, socioeconomic, lifestyle, and health-related factors were associated with CLBP. These results demonstrate the influence of these factors on CLBP in the general population and suggest that consideration of these factors may improve the management of CLBP.

The prevalence and severity of sick-leaves due to musculoskeletal disorders among workers in water supply; sewerage, waste management and remediation activities

The aim of this study was to analyse the nationwide data on sick leaves (SL) due to work-related musculoskeletal disorders among Slovenian workers in section E "water supply; sewerage, waste management and remediation activities" from NACE Rev2 classification. We report both, SL frequency (ie, number of cases) and SL severity (ie, average SL duration), stratified by body region, gender, age and divisions within the section. In addition, trends in SL data (year 2015-2019 difference) were analyzed. Throughout the analysed years, ∼9,000 workers were employed in the section, with male to female ratio at ∼ 4:1. The major findings are as follows: (i) low back disorders were by far the most prevalent, however, the mean SL duration was the highest for lower limb disorders; (ii) older age was associated with increased SL frequency and duration, irrespective of gender; (iii) male gender was consistently associated with larger SL duration, while the data on SL frequency is inconclusive, as older females had more frequent SL than older males; (iv) the effect of division was relatively minor and the comparisons are limited due to large discrepancies regarding the number of workers across divisions; (v) a slight increasing trend for both SL frequency and duration was observed from 2015 to 2019. In conclusion, particular attention in terms of early diagnosis and treatment of musculoskeletal disorders should be given to male workers and older workers in general in section E.

Multimedia Instructions for Motor Control Exercises in Patients With Chronic Nonspecific Low Back Pain

BACKGROUND

Low back pain (LBP) is one of the top 3 diseases that may lead to disability. Current treatment guidelines define exercise as a first-line treatment for nonspecific LBP (NSLBP). There are various evidence-based exercise approaches for treating NSLBP, and many of them include motor control principles. Motor control exercises (MCEs) are better than general exercises that do not include motor control principles. Many patients find learning these exercises complex and challenging, in that MCE exercises have no standard teaching method. The researchers of this study developed multimedia instructions for an MCE program to make teaching MCE easier; thus, more effective.

METHODS

The participants were randomized into multimedia or standard (face-to-face) instruction groups. We applied the same treatments to both groups at the same dosage. The only differences between groups were the exercise instruction methods. The multimedia group learned MCE from multimedia videos; the control group learned MCE from a physiotherapist with face-to-face instructions. Treatment lasted 8 weeks. We evaluated patients' exercise adherence with Exercise Adherence Rating Scale (EARS), pain with the Visual Analog Scale, and disability with Oswestry Disability Index. Evaluations were made before and after treatment. Follow-up evaluations were carried out 4 weeks after the end of treatment.

RESULTS

There was no statistically significant interaction between the group and time on pain, F2,56 = 0.068, P = .935, partial η2 = .002 and Oswestry Disability Index scores, F2,56 = 0.951, P = .393, partial η2 = .033. Also, there was no statistically significant interaction between the group and time on Exercise Adherence Rating Scale total scores F1,20 = 2.343, P = .142, partial η2 = .105.

CONCLUSIONS

This study showed that multimedia instructions for MCE have similar effects to standard (face-to-face) instructions on pain, disability, and exercise adherence in patients with NSLBP.

Availability, content and quality of commercially available smartphone applications for the self-management of low back pain: a systematic assessment

PURPOSE

Explore smartphone apps that may be recommended by clinicians for the self-management of low back pain.

METHODS

Prospectively registered systematic assessment of self-contained apps for self-management of low back pain on the Google Play and Apple App stores (Oceania), including ≥1 NICE low back pain and sciatica clinical guideline-recommended component and functioning without health professional input. Outcomes were quality (Mobile App Rating Scale; MARS), and self-management (Self-Management Support Checklist; SMS-14) and behaviour change potential (App Behaviour Change Scale; ABACUS).

RESULTS

25 apps were included. The average quality of included apps was acceptable (Mean MARS score of 3.9 out of a maximum possible 5). The self-management support and behaviour change potential of included apps appeared low (mean SMS-14 score was 3.4/14; mean ABACUS score was 5.4/21). The apps showed no significant correlation between app consumer ratings and MARS scores. App quality was significantly correlated with app price (p = 0.049) but not consumer ratings, however, these findings were based on a small number of studies and the overall model was not significant.

CONCLUSIONS

Smartphone apps for the self-management of low back pain are of average to good quality, with questionable potential for self-management and behaviour change. Clinicians should consider that few apps were designed to specifically incorporate self-management support and behaviour change potential when recommending apps to clients. Further development in these areas of app design would be of benefit.Implications for RehabilitationSmartphone apps have the potential to improve LBP self-management outcomes, however, apps are not well regulated and the quality of information and advice provided is often low quality.The findings from this systematic assessment indicate that LBP self-management apps have limited self-management support and behaviour change potential features.Recommendation of current smartphone apps for LBP should take into consideration that although apps are of acceptable quality they are not specifically designed with self-management support and behaviour change principles.App quality does not appear to be associated with consumer ratings, however, there may be a positive association between app price and quality which requires further investigation.

Associations Between Allergies, Walking, Sedentary Time, and Low Back Pain

PURPOSE

To examine associations between allergies, low back pain (LBP), walking, and sedentary time in a representative sample of adults aged 50 years and older.

DESIGN

A cross-sectional, correlational study.

METHODS

We used the 2014-2015 Korean National Health and Nutrition Examination Survey. Allergies of interest included allergic rhinitis, asthma, and atopic dermatitis. Adequate walking was defined as walking five or more days per week. Sedentary time was categorized as <7 h vs. ≥7 h. Logistic regression was performed to examine the association between allergies and LBP, controlling for demographics and lifestyle. Subgroup analyses were conducted to investigate the role of walking and sedentary lifestyle in LBP among those with or without allergies.

RESULTS

Of 4,897 respondents, 23.1% reported LBP. After controlling for covariates, individuals with allergies were 1.68 times more likely to have LBP than those without allergies. In the non-allergy group, those with inadequate walking and sedentary lifestyles were nearly twice as likely to report LBP than those with adequate walking and without sedentary lifestyles. However, this trend was not observed in the patients with allergy diagnoses.

CONCLUSIONS

We confirmed associations between lifetime allergy diagnosis and LBP. A protective role of physical activity and non-sedentary lifestyle in LBP remained only among those without allergies.

CLINICAL IMPLICATIONS

Nurses should emphasize the impact of allergies on LBP. The advantages of walking and non-sedentary lifestyles for preventing or relieving chronic conditions should be routinely included in patient education; however, their preventive role in LBP should be underscored for those without allergies.

The functional lumbar index: Validation of a novel clinical assessment tool for individuals with low back pain

STUDY DESIGN

Retrospective Diagnostic Cohort Study.

LEVEL OF EVIDENCE

Level 3b.

OBJECTIVES

To examine the concurrent and predictive validity of a novel clinical assessment tool, the Functional Lumbar Index (FLI).

BACKGROUND

Lumbar surgeries have increased exponentially in the past decade, adding to healthcare costs without improving outcomes. Limitations in clinicians' abilities to identify those individuals who are most likely to benefit from surgery may be enhanced with an effective physical assessment tool.

METHODS

The FLI was assessed on 291 individuals (179 conservative and 113 pre-surgical) seeking care for low-back pain (LBP) over a 2.5-year period. The FLI consists of several physical performance tests (PPT) with a novel criterion-based scoring system. Pearson correlations and Poisson regression analysis were used to establish concurrent and predictive validity at alpha = 0.05.

RESULTS

The subscale FLI components showed good to excellent inter-rater reliability with intraclass correlation coefficient values as follows: front plank = .993, right side plank = .824, left side plank .861, Sorensen = 0.836, overhead squat = 0.937. A statistically significant, moderate negative correlation was observed between FLI and modified Oswestry Disability Index (r = -0.540, p < .001). Regression analysis showed the FLI as the only significant predictor (p = .004) of failed conservative management for individuals with LBP. An ROC curve showed significant group prediction of the FLI with an AUC of 0.788 (p < .001) and cut-off score of 7.5.

CONCLUSION

The FLI is a reliable and valid measure for predicting failed conservative care management in patients with LBP. Clinicians are encouraged to use the FLI as part of their physical assessment when screening individuals with LBP who might need surgical intervention. Further research is needed to determine validity of the FLI in other patient populations.

S, Neelam S. Nonspecific low back pain in sedentary workers: A narrative review

A sedentary lifestyle is a risk factor, significantly increasing the incidence of low back pain (LBP). Higher levels of sedentary lifestyle were witnessed in the workers who spent the greatest amount of their time in sitting positions in the workplace and during free time. The incidence and prevalence of low back pain in sedentary workers were 14-37% and 34-62%. Noticeably, the people with low back pain had higher productivity loss. It specifies more research is required to help individuals with back pain to stay in their work. The main intention of this study briefly reviews the risk factors, associated adaptations, and Interventions in physical therapy for preventing and managing nonspecific low back pain in sedentary workers. To do this review, Information was gathered from the offline library resources and online electronic search databases (Scopus, COCHRANE, PUBMED). The keywords used were low back pain, sedentary workers, risk factors, adaptations, exercise therapy, and sedentary lifestyle. The prognosis and management of low back pain were greatly influenced by several risk factors related to physical, psychological, and occupational factors. During the transition of low back pain from acute to chronic stages, adaptations in various domains like psychological, behavioral, and neuromuscular changes are seen. Exercise therapy itself or in addition to other therapeutic approaches is successful in preventing and treatment of nonspecific low back pain in sedentary workforces. By identifying associated risk factors, and changes adapted by individual patients, Therapists can design proper exercise therapeutic approaches that will provide more effective interventions.

Effect of online physical therapy on workplace accident-related outcomes in nursing care worker: study protocol of a multicentre randomised controlled trial

INTRODUCTION

According to the 2017 data, occupational accidents are more common in social welfare facilities compared with other industries; in particular, the number of occupational accidents resulting in four or more days of absence from work due to low back pain (LBP) or falls has increased and is considered problematic. Although physical therapy has been demonstrated to be effective in preventing LBP and falls in older adults living in the community, no randomised controlled trials have examined whether individual online physical therapy can prevent LBP and falls in nursing care workers (NCW).

METHODS AND ANALYSIS

A total of 120 NCW aged 20 years or older will be randomly assigned to an online individualised therapy group (ITG) or usual group (UG) after obtaining informed consent. We defined an NCW as a person who assists disabled and elderly persons with eating, bathing and toileting activities in social welfare facilities. We will follow-up the participants 12 months after the start of the intervention and compare the results at 3, 6 and 12 months. The primary endpoint will be the Oswestry Disability Index (ODI); ITG participants will receive professional advice on LBP and musculoskeletal problems from a physical therapist via online interview and email as often as they wish over a 6-month period; UG participants will only have access to brochures and video feeds related to LBP and fall prevention. Owing to the nature of the study, blinding the participants and interventionists is not possible; however, the outcomes will be assessed via a web-based questionnaire to prevent detection bias. The null hypothesis is that there is no clinically important difference in the primary outcome between the two treatment groups and that a decrease in the ODI score of at least 20% is clinically meaningful.

ETHICS AND DISSEMINATION

The Ethics Committee of the Japanese Society of Occupational Medicine approved the protocol of this study. The results of this study will be disseminated through peer-reviewed journals and conference presentations.

The Dutch Multidisciplinary Occupational Health Guideline to Enhance Work Participation Among Low Back Pain and Lumbosacral Radicular Syndrome Patients

Purpose Based on current scientific evidence and best practice, the first Dutch multidisciplinary practice guideline for occupational health professionals was developed to stimulate prevention and enhance work participation in patients with low back pain (LBP) and lumbosacral radicular syndrome (LRS). Methods A multidisciplinary working group with health care professionals, a patient representative and researchers developed the recommendations after systematic review of evidence about (1) Risk factors, (2) Prevention, (3) Prognostic factors and (4) Interventions. Certainty of the evidence was rated with GRADE and the Evidence to Decision (EtD) framework was used to formulate recommendations. High or moderate certainty resulted in a recommendation "to advise", low to very low in a recommendation "to consider", unless other factors in the framework decided differently. Results An inventory of risk factors should be considered and an assessment of prognostic factors is advised. For prevention, physical exercises and education are advised, besides application of the evidence-based practical guidelines "lifting" and "whole body vibration". The stepped-care approach to enhance work participation starts with the advice to stay active, facilitated by informing the worker, reducing workload, an action plan and a time-contingent increase of work participation for a defined amount of hours and tasks. If work participation has not improved within 6 weeks, additional treatments should be considered based on the present risk and prognostic factors: (1) physiotherapy or exercise therapy; (2) an intensive workplace-oriented program; or (3) cognitive behavioural therapy. After 12 weeks, multi-disciplinary (occupational) rehabilitation therapy need to be considered. Conclusions Based on systematic reviews and expert consensus, the good practice recommendations in this guideline focus on enhancing work participation among workers with LBP and LRS using a stepped-care approach to complement existing guidelines focusing on recovery and daily functioning.

The effectiveness of post-professional physical therapist training in the treatment of chronic low back pain using a propensity score approach with machine learning

RATIONALE

Low back pain (LBP) is a leading cause of disability in the United States creating substantial hardships through negative social, financial, and health effects. Chronic low back pain (CLBP) accounted for above half of patients treated in physical therapy (PT) clinics for LBP. However, research shows small benefit from PT in CLBP treatment. Preliminary evidence suggests clinician-level training variables may affect outcomes, but requires further investigation to determine whether patients with CLBP benefit from treatment by providers with post-professional training. This study examined the relationship between clinician training levels and patient-reported outcomes in CLBP treatment.

METHODS

Physical therapies were surveyed using a large patient outcome assessment system to determine and categorise them by level of post-professional education. To account for the possibility that clinicians with higher levels of training are referred more-complex patients, a machine learning approach was used to identify predictive variables for clinician group, then to construct propensity scores to account for differences between groups. Differences in functional status score change among pooled data were analysed using linear models adjusted for propensity scores.

RESULTS

There were no clinically meaningful differences in patient outcomes when comparing clinician post-professional training level. The propensity score method proved to be a valuable way to account for differences at baseline between groups.

CONCLUSION

Post-professional training does not appear to contribute to improved patient outcomes in the treatment of CLBP. This study demonstrates that propensity score analysis can be used to ensure that differences observed are true and not due to differences at baseline.

Reducing the burden of low back pain: results from a new microsimulation model

Background

Low back pain (LBP) causes the highest morbidity burden globally. The purpose of the present study was to project and compare the impact of three strategies for reducing the population health burden of LBP: weight loss, ergonomic interventions, and an exercise program.

Methods

We have developed a microsimulation model of LBP in Canada using a new modeling platform called SimYouLate. The initial population was derived from Cycle 1 (2001) of the Canadian Community Health Survey (CCHS). We modeled an open population 20 years of age and older. Key variables included age, sex, education, body mass index (BMI), type of work, having back problems, pain level in persons with back problems, and exercise participation. The effects of interventions on the risk of LBP were obtained from the CCHS for the effect of BMI, the Global Burden of Disease Study for occupational risks, and a published meta-analysis for the effect of exercise. All interventions lasted from 2021 to 2040. The population health impact of the interventions was calculated as a difference in years lived with disability (YLDs) between the base-case scenario and each intervention scenario, and expressed as YLDs averted per intervention unit or a proportion (%) of total LBP-related YLDs.

Results

In the base-case scenario, LBP in 2020 was responsible for 424,900 YLDs in Canada and the amount increased to 460,312 YLDs in 2040. The effects of the interventions were as follows: 27,993 (95% CI 23,373, 32,614) YLDs averted over 20 years per 0.1 unit change in log-transformed BMI (9.5% change in BMI) among individuals who were overweight and those with obesity, 19,416 (16,275, 22,557) YLDs per 1% reduction in the proportion of workers exposed to occupational risks, and 26,058 (22,455, 29,661) YLDs averted per 1% increase in the proportion of eligible patients with back problems participating in an exercise program.

Conclusions

The study provides new data on the relationship between three types of interventions and the resultant reductions in LBP burden in Canada. According to our model, each of the interventions studied could potentially result in a substantial reduction in LBP-related disability.

Association of musculoskeletal pain with the achievement of treatment targets for type 2 diabetes among primary care patients

AIMS

To assess the association of diagnosed musculoskeletal (MS) pain (low back, neck, shoulder, and knee pain; and the number of pain sites) with the achievement of targets for glycosylated haemoglobin A1c (HbA1c), low-density-lipoprotein cholesterol (LDL), and systolic blood pressure (SBP) among primary care patients with type 2 diabetes (T2D).

METHODS

The cross-sectional study population consisted of 3478 patients with a registry-based T2D diagnosis and available registry-based data on MS pain diagnoses, covariates, and outcomes between 2016 and 2019. Logistic regression analysis was used to evaluate the study aims.

RESULTS

Overall, 22% had at least one of the four types of MS pain, and 73%, 57%, and 51% achieved the treatment targets of HbA1c, LDL, and SBP, respectively. T2D patients with or without MS pain did not differ in their achievement of T2D treatment goals. Of pain locations, low back pain was associated with higher rates of achievement of the LDL target (OR 1.29, 95% CI 1.01-1.65), but the association was attenuated in the adjusted model.

CONCLUSIONS

MS pain was relatively prevalent among primary care patients with T2D, but did not influence the achievement of T2D treatment goals.

Predictors of older adults' chronic pain in the context of opioid adverse drug events

BACKGROUND

Factors predictive of chronic pain in older adults could help focus prevention and treatment efforts for those most at risk of chronic pain.

PURPOSE

The objective of the study was to describe demographic and pain self-management factors predictive of chronic pain in the context of opioid adverse drug events (ADEs) reported for a cohort of older adults within the same year.

METHOD

The design was a post hoc analysis of 9,095 cases aged 65 years and older from the 2019 National Health Interview Survey that reported chronic pain and 380 cases aged 65 years and older with opioid adverse events reported to the Food and Drug Administration Adverse Event Reporting System (FAERS) during the second quarter of 2019. Logistic regression predicted chronic pain.

RESULTS

Less than a baccalaureate education increased the odds of chronic pain by 28.0% while lower income minimally increased the odds. Male gender increased the odds of chronic pain by 12.0%. Increased age minimally increased the odds for chronic pain. Use of opioids, other pain treatments, complementary treatments, and antidepressants were all associated with increased odds of chronic pain. FAERS opioid ADEs ranged from pruritus to death, with death identified in 16 (4.2%) cases. Misuse, abuse, or dependence was documented in 1.8% of cases.

CONCLUSIONS AND IMPLICATIONS

Less-educated older adults may be particularly at risk of chronic pain and should be routinely assessed and prescribed safe and efficacious pain self-management as needed. Some men may need additional support to use pain treatments.

Assessing Relationships between Physically Demanding Work and Late-Life Disability in Italian Nonagenarian Women Living in a Rural Area

As more and more persons live into their 90s and beyond, investigating causes of disability in the oldest-old population is relevant for public health implications to plan preventive strategies and rehabilitation interventions. A negative association between physically demanding work and midlife physical function has been shown, but there is a paucity of longitudinal studies investigating possible work-related long-term effects in the oldest old. This study investigates the relationship between physically demanding work exposure and late-life physical performances, disability, general health status, and quality of life in a sample of women aged 90 years and over inside the Mugello Study. Sociodemographic data, cognitive and functional status, lifestyle, medical history, drug use, and work history were collected from 236 participants. Farmers had a lower percentage of individuals with preserved independence in basic activities of daily living compared to other occupations. However, in the multivariate analysis, only a higher cognitive function remained associated with functional independence. While confirming the well-known association between cognitive and functional decline in very old age, our results do not support the hypothesis that the negative effects of physical work exposure observed in midlife are relevant to predict disability in nonagenarian women.

Association between back and neck pain and workplace absenteeism in the USA: the role played by walking, standing, and sitting difficulties

PURPOSE

There is a paucity of literature identifying factors that influence the back and neck pain (BNP)-workplace absenteeism relationship. Therefore, this study aimed to investigate the association between BNP and workplace absenteeism and potential mediating variables in a large sample of the US population.

METHODS

Nationally representative data collected in 2019 from the RAND American Life Panel (ALP) were used for this retrospective study. Workplace absenteeism was defined as the number of days of absence in the past 12 months for health-related reasons (count variable), while BNP corresponded to the presence of back pain due to spinal stenosis, back pain due to other causes, or neck pain (dichotomous variable). Control variables included sex, age, ethnicity, marital status, education, occupation, annual family income, health insurance, obesity, and diabetes. There were eight influential variables (depression, anxiety, sleep disorder, alcohol dependence, opioid dependence, walking difficulty, standing difficulty, and sitting difficulty). The association between BNP and workplace absenteeism was analyzed using a negative binomial regression model.

RESULTS

There were 1,471 adults aged 22-83 years included in this study (52.9% of men; mean [standard deviation] age 44.5 [13.0] years). After adjusting for control variables, BNP was positively and significantly associated with workplace absenteeism (incidence rate ratio = 1.40, 95% confidence interval: 1.07-1.83). Walking, standing, and sitting difficulties individually explained between 24 and 43% of this association.

CONCLUSIONS

Workplace interventions focusing on the management of BNP and overcoming difficulties in walking, standing, and sitting, potentially utilizing exercise, therapy, and ergonomic interventions, may prevent absenteeism.

Association between Dietary Protein Intake, Regular Exercise, and Low Back Pain among Middle-Aged and Older Korean Adults without Osteoarthritis of the Lumbar Spine

This study aimed to evaluate the effect of dietary protein intake and regular exercise on low back pain (LBP) using data from the Korea National Health and Nutrition Examination Survey. A total of 2367 middle-aged and older adults (≥50 years) who underwent dual-energy X-ray absorptiometry and plain radiography of the lumbar spine were included. LBP was defined using a questionnaire to determine the presence of LBP lasting more than 30 days in the preceding three months. Twenty-four-hour dietary recall data were used to estimate protein intake, and regular exercise was assessed using the International Physical Activity Questionnaire. Multivariable logistic regression analysis revealed that men who did not perform regular exercise had a high probability of LBP (odds ratio [OR] 2.34; 95% confidence interval [CI] 1.24−4.44). Low protein intake (<0.8 g/kg/day) was associated with high odds for LBP in women (OR 1.83; 95% CI 1.12−2.99). Low protein intake and lack of regular exercise were also associated with a higher probability of LBP in women (OR 2.91; 95% CI 1.48−5.72). We recommend that women over 50 years of age consume the recommended daily amount of protein to prevent LBP and engage in regular exercise.

The Effect of Exercise Programs on Pain Management and Motor Control in Patients with Nonspecific Chronic Low Back Pain: A Randomized Matched Subjects Trial

Backgroud:

Many exercise approaches have been suggested for the treatment of nonspecific chronic low back pain. However, the best exercise approach is still unknown. The purpose of this study was to compare the effect of three exercise approaches based on the Postural Restoration Institute (PRI) and National Academy of Sports Medicine (NASM) on the pain management and motor control of men with nonspecific chronic low back pain.

Methods:

The study was designed with matched subjects. Thirty-three participants were randomly assigned to three training groups: NASM (n = 11), PRI (n = 11), and NASM-PRI integration (n = 11). Interventions: The participants in each group performed the exercise for eight weeks, three sessions per week and about one hour each session. Pain was measured using a visual analog scale (VAS) scale and functional disability using the Roland–Morris questionnaire. Also, the movement control impairment was measured by the movement control impairment test set.

Results:

Repeated measures ANOVA showed no significant interaction effect between pain perception, functional disability, and movement control impairment of the groups (P >.05).

Conclusions:

The findings suggest that different types of exercise rehabilitation were not significantly different on pain reduction, functional disability, and movement control impairment. It is suggested that the participant's preference for an approach should also be considered for encouraging them to adhere to exercise.

INFLUENCE OF PHYSICAL ACTIVITY AND TIME IN THE SITTING POSITION ON THE CONDITION OF LOW BACK PAIN AMONG UNIVERSITY STUDENTS

ABSTRACT Objective: To verify the influence of sedentary behavior and physical activity on the prevalence and situation of low back pain in medical students at a higher education institution. Methods: Cross-sectional study with a quantitative approach, conducted with 220 students. Data were collected between January and February 2021, using the Roland-Morris Disability Questionnaire. Data were analyzed using the Statistical Package for the Social Sciences Program. Values of p ≤ 0.05 were accepted as statistically significant. Results: Sixty-five percent of the participants were female, the average student age was 24.19 years, and a predominance of students were in the clinical cycle (60.9%). Of the total sample, 75.9% (n=167) stated that they performed physical activities and 28.2% (n=62) responded that they spend between 7-10 hours sitting studying. The prevalence of low back pain was high (84.1%; n=185), however, only 1.5% (n=3) had scores indicative of functional disability. Women (Mean=5.07, SD=0.35) had greater functional disability than men (Mean=3.33, SD=0.35; p=0.008). Sedentary students had greater disability (Mean=5.79, SD=4.55) than active students (Mean=4.04, SD=3.62; p=0.007); individuals who spent more than 7 hours a day sitting also had higher scores (p=0.02). Conclusion: The findings indicated a significant self-reported prevalence of low back pain among medical students, with greater functional disability in females, sedentary individuals, and those who sat for more than 7 hours a day.

When Treating Coexisting Low Back Pain and Hip Impairments, Focus on the Back: Adding Specific Hip Treatment Does Not Yield Additional Benefits-A Randomized Controlled Trial

OBJECTIVE

To determine whether adding hip treatment to usual care for low back pain (LBP) improved disability and pain in individuals with LBP and a concurrent hip impairment.

DESIGN

Randomized controlled trial.

METHODS

Seventy-six participants (age, 18 years or older; Oswestry Disability Index, 20% or greater; numeric pain-rating scale, 2 or more points) with LBP and a concurrent hip impairment were randomly assigned to a group that received treatment to the lumbar spine only (LBO group) (n = 39) or to one that received both lumbar spine and hip treatments (LBH group) (n = 37). The individual treating clinicians decided which specific low back treatments to administer to the LBO group. Treatments aimed at the hip (LBH group) included manual therapy, exercise, and education, selected by the therapist from a predetermined set of treatments. Primary outcomes were disability and pain, measured by the Oswestry Disability Index and the numeric pain-rating scale, respectively, at baseline, 2 weeks, discharge, 6 months, and 12 months. The secondary outcomes were fear-avoidance beliefs (work and physical activity subscales of the Fear-Avoidance Beliefs Questionnaire), global rating of change, the Patient Acceptable Symptom State, and physical activity level. We used mixed-model 2-by-3 analyses of variance to examine group-by-time interaction effects (intention-to-treat analysis).

RESULTS

Data were available for 68 patients at discharge (LBH group, n = 33; LBO group, n = 35) and 48 at 12 months (n = 24 for both groups). There were no between-group differences in disability at discharge (-5.0; 95% confidence interval [CI]: -10.9, 0.89; P = .09), 12 months (-1.0; 95% CI: -4.44, 2.35; P = .54), and all other time points. There were no between-group differences in pain at discharge (-0.2; 95% CI: -1.03, 0.53; P = .53), 12 months (0.1; 95% CI: -0.53, 0.72; P = .76), and all other time points. There were no between-group differences in secondary outcomes, except for higher Fear-Avoidance Beliefs Questionnaire (work subscale) scores in the LBH group at 2 weeks (-3.35; 95% CI: -6.58, -0.11; P = .04) and discharge (-3.45; 95% CI: - 6.30, -0.61; P = .02).

CONCLUSION

Adding treatments aimed at the hip to usual low back physical therapy did not provide additional short- or long-term benefits in reducing disability and pain in individuals with LBP and a concurrent hip impairment. Clinicians may not need to include hip treatments to achieve reductions in low back disability and pain in individuals with LBP and a concurrent hip impairment.

Professional Status of Persistent Spinal Pain Syndrome Patients after Spinal Surgery (PSPS-T2): What Really Matters? A Prospective Study Introducing the Concept of "Adapted Professional Activity" Inferred from Clinical, Psychological and Social Influence

Persistent Spinal Pain Syndrome Type 2 (PSPS-T2) represents a main cause of work disruption. Beyond its societal consequences, occupational inactivity is responsible for a major decrease in physical/mental health in individuals but remains poorly analyzed. We designed a study to prospectively examine Professional Status (PS) evolution and its association with key bio-psychological markers. Data from 151 consecutively included working-age PSPS-T2 patients were analyzed to determine the proportion of professional inactivity and the relationships between PS and Social Gradient of Health (SGH), Numeric Pain Rating Scale (NPRS), EuroQol 5-Dimensional 5-Level (EQ-5D-5L), Oswestry Disability Index (ODI), Hospital Anxiety and Depression Scale (HADS), and Fear-Avoidance Belief Questionnaire work subscale (FABQ-W). Despite optimized medical management, 73.5% of PSPS-T2 patients remained inactive after 1 year of follow-up/p = 0.18. Inactive patients presented a low SGH/p = 0.002, higher NPRS/p = 0.048, lower EQ-5D-5L/p < 0.001, higher ODI/p = 0.018, higher HADS-D/p = 0.019 and higher FABQ-W/p < 0.001. No significant mediation effect of FABQ-W on SGH consequences regarding PS was observed in our structural model/p = 0.057. The link between unemployment and bio-psycho-social pain dimensions appears bidirectional and justifies intense collaboration with social workers. Optimizing therapeutical sequencing towards personalized professional plans implies restoring "Adapted Physical Function" as an initial goal, and tailoring an "Adapted Professional Activity", matching with patient expectations and capabilities, as a final objective.

Prevalence, Characteristics, Association Factors of and Management Strategies for Low Back Pain Among Italian Amateur Cyclists: an Observational Cross-Sectional Study

Background

Low back pain (LBP) is a burdensome problem affecting amateur cyclists. This cross-sectional study analysed Italian amateur cycling cohort’s demographic and sport-specific characteristics, the prevalence and characteristics of LBP among this population, its possible association factors, the management strategies adopted to deal with LBP and the sample’s beliefs among possible LBP triggers. A web-based cross-sectional survey was created. The questionnaire included 56 questions divided into six sections, querying the sample’s demographic, clinical, and cycling characteristics. Binomial logistic regression with a Wald backward method was performed to ascertain the effects of some covariates (“Sex”, “Age”, “Body Mass Index”, “Sleep hours”, “Work type”, “Cycling year”, “Number of training sessions per week”, “Stretching sessions”, “Being supervised by a coach or following a scheduled training”, “Other sports practised regularly”, “Number of cycling competitions per year”, “Past biomechanic visits”, “Specific pedal training”, “LBP before cycling”) on the likelihood of developing LBP in the last 12 months.

Results

A total of 1274 amateur cyclists answered the survey. The prevalence of LBP appeared to be 55.1%, 26.5% and 10.8% in life, in the last 12 months and the last 4 weeks, respectively. The final model of the logistic regression included the covariates “Sex”, “Work type”, “Cycling year”, “Being supervised by a coach or following a scheduled training”, “Other sports practised regularly”, “Specific pedal training”, “LBP before cycling”, among which “Cycling year” (variable “Between 2 and 5 years” vs. “Less than 2 years”, OR 0.48, 95% CI [0.26–0.89]), “Being supervised by a coach or following a scheduled training” (OR 0.53, 95% CI [0.37–0.74]), “Specific pedal training” (OR 0.69, 95% CI [0.51–0.94]), and “LBP before cycling” (OR 4.2, 95% CI [3.21–5.40]) were found to be significant.

Conclusions

The prevalence of LBP among Italian amateur cyclists seems to be less frequent compared to the general population. Moreover, undergoing previous specific pedal training and being supervised by a coach or following scheduled training drew a negative association with LBP development. This evidence highlights the importance of being overseen by specific sport figures that could offer a tailored evidence-based training to reach good physical level and to practise sports safely.

Association between radicular low back pain and constipation: a retrospective cohort study using a real-world national database

INTRODUCTION

Previous observational studies have reported an association between lumbosacral radiculopathy (LSR), a form of low back pain (LBP) with nerve root involvement, and constipation. However, it is unclear whether this association is due to confounding variables such as comorbidities and medications.

OBJECTIVES

This study explores the possible association between LSR and constipation, with the hypothesis that adults with LSR have increased odds of developing constipation compared with those with nonradicular LBP.

METHODS

Adults aged 18 to 49 years with incident LSR and nonradicular LBP were identified from a national 70 million patient electronic health records network (TriNetX). Propensity score matching (PSM) was used to control for covariates and determine the odds ratio (OR) of constipation over a 1-year follow-up. Lumbar stenosis, cauda equina syndrome, and inflammatory bowel diseases were excluded.

RESULTS

After PSM, 503,062 patients were in each cohort. Before PSM, the likelihood of constipation was identical between cohorts (LSR 10.8% vs 10.9%; OR [confidence interval] = 0.99 [0.98-1.0], P = 0.251). This association was unchanged after PSM (LSR 10.8% vs 11.1%; OR [confidence interval] = 0.98 [0.97-0.99]; P = 0.003).

CONCLUSIONS

The study hypothesis can be refuted given that the OR approximated the null in a large propensity-matched sample. Patients with LSR have equivalent odds of constipation compared with those with nonradicular LBP, suggesting that LSR is not a direct cause of constipation. The similar risk of constipation between cohorts could be explained by factors common to LBP in general, such as pain severity, physical inactivity, and constipating medications.

Research Relating to Low Back Pain and Physical Activity Reported Over the Period of 2000-2020

Background

Low back pain (LBP) is a highly prevalent musculoskeletal disorder that contributes to the greatest degree of disability worldwide. It has become a very serious public health problem that has attracted considerable research interest. The number of publications associated with LBP and physical activity (PA) is gradually increasing. Nevertheless, few studies have utilised visualisation in analysing the general aspects of this field. Therefore, we aimed to provide a systematic overview of global scientific research related to low back pain and physical activity from 2000 to 2020. It has significant benefits in terms of providing researchers with the status and trends of research on low back pain and physical activity.

Methods

Publications on Science Citation Index-Expanded of Web of Science from 2000 to 2020 were searched, and publications relevant to LBP and PA were analysed using Citespace and SPSS. Analyses mainly included cooperation amongst authors, countries and institutions; co-occurrence analysis of keywords; and co-citation analysis of references, revealing productive researchers and contributing institutions tracking the status and trend of research fields.

Results

Results of linear regression analysis showed that the number of publications on LBP and PA studies increased significantly (p<0.001). The subject categories predominantly focused on orthopaedics (2579, 26.54%), rehabilitation (2544, 26.18%) and sport sciences (2015, 25.44%). The United States had the highest number of published papers (2700, 27.789%) and citations (86, 958). In terms of the number of publications, amongst the top 20 journals, Spine contributed the most, whilst the British Journal of Sports Medicine had the highest impact factor (IF₂₀₁₉, 12.022). The University of Sydney had the highest number of publications (330 publications). Maher published the most papers (123 papers) and had the highest H-index (41). Several citation articles and keywords (such as aerobic, obesity and fear-avoidance beliefs) can be used to provide frontier clues for research on LBP and PA.

Conclusion

The results of our study may provide information, such as research trends and frontiers of research and collaborating partners, institutions and countries, on LBP and PA.

Characteristics of ambulatory spine care visits in the United States, 2009-2016

BACKGROUND

Back pain is a leading reason for seeking care in the United States (US), and is a major cause of morbidity.

OBJECTIVE

To analyze demographic, patient, and visit characteristics of adult ambulatory spine clinic visits in the United States from 2009-2016.

METHODS

Data from the National Ambulatory Medical Care Survey from 2009-2016 were used and were sample weighted.

RESULTS

Most patients presenting for ambulatory spine care were 45-64 years (45%), were most commonly female (56.8%), and private insurance (45%) and Medicare (26%) were most common payors. The percentage of visits for spine care done at a primary care setting was 50.1% in 2009-2010 and 48.3% in 2014-2015. Approximately 15.5% were seen in orthopedic surgery clinics in 2009-2010 and 7.3% in 2015-2016. MRI was utilized in 11.7% in 2009-2010 and 11.0% in 2015-2016. Physical therapy was prescribed in 13.2% and narcotic analgesic medications were prescribed in 36.2% of patients in 2015-2016.

CONCLUSIONS

MRI was used more frequently than guidelines recommended, and physical therapy was less frequently utilized despite evidence. A relatively high use of opiates in treatment of back pain was reported and is concerning. Although back pain represents a substantial public health burden in the United States, the delivery of care is not evidence-based.

Effects of adding neural mobilization to traditional physical therapy on pain, functional disability, and H-reflex in patients after lumbar laminectomy: A randomized controlled trial

OBJECTIVE

To investigate whether adding neural mobilization to a standard postoperative physical therapy program could improve the outcomes of patients after lumbar laminectomy.

DESIGN

A single blinded randomized controlled trial.

SETTING

Outpatient setting.

PARTICIPANTS

Sixty participants of both sexes who had undergone lumbar laminectomy.

INTERVENTIONS

Participants were allocated randomly to two groups; study and control groups. All patients received a standard postoperative physical therapy program. Those in the study group received additional neural mobilization in the form of straight leg raising and dorsiflexion with two-ended slider. Treatment was administered three times/week for six successive weeks.

OUTCOME MEASURES

Visual analog scale (VAS), Oswestry disability index (ODI), and H-reflex latency were measured pre and post-treatment.

RESULTS

The mean age of participants was 44.23 ± 4.64 and 45.3 ± 5.3 in study and control groups respectively (P > 0.05). There were statistically significant differences in VAS, ODI, and H-reflex latency in favor of the study group (P < 0.05). The mean ± SD for VAS, ODI, and H-reflex latency pre vs post treatment was 6.13 ± 1.22 vs 1.40 ± 0.77, 64.46 ± 4.05 vs 16.86 ± 2.55, and 32.07 ± 2.76 vs 27.46 ±1.79 in study group and 5.86 ± 1.07 vs 2.46 ± 0.73, 63.93 ± 3.91 vs 23.40 ± 2.93, and 31.76 ± 2.69 vs 29.4 ± 1.94 in control group, respectively.

CONCLUSIONS

Neural mobilization combined with traditional physical therapy program achieved better improvement in pain, functional disability and H-reflex in patients who underwent decompressive laminectomy than traditional physical therapy program only.

Effect of exercise training on improving sleep disturbances: a systematic review and meta-analysis of randomized control trials

OBJECTIVES

Exercise training has beneficial effects on various aspects of health. This study aimed to investigate the effect of exercise training on the improvement of sleep disturbances using systematic review and meta-analysis of randomized control trials.

METHOD

Four indexes of scientific information including PubMed, Web of Science, Scopus, and the Cochrane library were selected and all manuscripts of these sources were searched in English until January 2021. The studies were screened and finally, the studies were entered into meta-analysis and the Standardized Mean Difference (SMD) was calculated, and the analyzes were performed based on the random effects method. Publication bias and heterogeneity were examined in all analyzes.

RESULT

A total of 32 studies were included in the meta-analysis. Meta-analysis showed that exercise training is effective in improving sleep quality (SMD = -0.85 and confidence interval (CI) was -1.16-0.54; P < 0.001). Exercise training improving insomnia (SMD = -0.87 and CI was -1.68-0.06; P = 0.036). Exercise training improves sleepiness (SMD = -0.38 and CI was -0.68-0.07; P = 0.016), obstructive sleep apnea (SMD = -0.40 and CI was -0.67-0.14; P = 0.003) and restless legs syndrome (SMD = -1.02 and CI was -1.56-0.49; P < 0.001).

DISCUSSION

Exercise training has beneficial effects on a variety of sleep disturbances and therefore it can be said that providing the necessary conditions for exercise training can play a major role in promoting health, especially since this type of intervention is a non-pharmacological intervention.

Occupational Related Upper and Low Back Pain Among the Working Population of Ethiopia: Systematic Review and Meta-Analysis

BACKGROUND

Back pain, such as upper and low back pain are among the most common musculoskeletal conditions that can cause major public health and socioeconomic problems. Back pain is one of the leading causes of disability that reduces worker performance and well-being and increases absence from work, which can cause an enormous economic burden. In developing countries, particularly in Ethiopia, there is no adequate evidence on the overall prevalence of occupational-related upper and low back pain, and they remain less prioritized and empirically unrepresented. Therefore, this study aimed to determine the prevalence of occupational-related upper and low back pain among the working population of Ethiopia.

METHODS

This systematic review and meta-analysis considered studies conducted in Ethiopia, written in English, and published from 2017 to 2020. Articles were searched from 9 electronic databases (Web of Science, SCOPUS, PubMed, Google Scholar, CINAHL, Cochrane Library, African Index Medicus, African Journals Online database, and Science Direct) using a combination of Boolean logic operators, Medical Subject Headings, and main keywords. The quality assessment of the articles was performed using the Joanna Briggs Institute Critical Appraisal tools to determine the relevance of the articles to the study. A random effects model was used to estimate the pooled prevalence, the 95% confidence interval, and the degree of heterogeneity among the included studies. Sensitivity analyses were performed to identify the influence of outliers and to identify sources of heterogeneity.

RESULTS

Of the 1114 studies identified from the included databases, 20 studies were included in the systematic review and meta-analysis. The pooled prevalence of occupational-related upper and low back pain in the previous year was (27.1% [95% CI: 18.4, 37.9]) and (54.2% [95% CI: 48.2, 60.0]), respectively. Based on a subgroup analysis by publication year, study population, and regions where the studies were conducted, the prevalence of upper back pain was (43.8% [95% CI: 39.3, 47.7]), (34.7% [95% CI: 33.1, 36.2]), and (36.2% [95% CI: 33.6, 39.0]), respectively, while the prevalence of low back pain was (61.8% [95% CI: 58.9, 64.6], (52.8% [95% CI: 51.3, 54.3]), and (55.2% [95% CI: 51.4, 59.0]), respectively.

CONCLUSIONS

This systematic review and meta-analysis found that 54.2% of the included study participants experienced low back pain in the previous year, while 27.1% experienced upper back pain. The highest prevalence was reported among pedestrian back-loading women.

Intervertebral Disc and Adipokine Leptin-Loves Me, Loves Me Not

Leptin—the most famous adipose tissue-secreted hormone—in the human body is mostly observed in a negative connotation, as the hormone level increases with the accumulation of body fat. Nowadays, fatness is becoming another normal body shape. Fatness is burdened with numerous illnesses—including low back pain and degenerative disease of lumbar intervertebral disc (IVD). IVD degeneration and IVD inflammation are two indiscerptible phenomena. Irrespective of the underlying pathophysiological background (trauma, obesity, nutrient deficiency), the inflammation is crucial in triggering IVD degeneration. Leptin is usually depicted as a proinflammatory adipokine. Many studies aimed at explaining the role of leptin in IVD degeneration, though mostly in in vitro and on animal models, confirmed leptin’s “bad reputation”. However, several studies found that leptin might have protective role in IVD metabolism. This review examines the current literature on the metabolic role of different depots of adipose tissue, with focus on leptin, in pathogenesis of IVD degeneration.

The burden of low back pain in Brazil: estimates from the Global Burden of Disease 2017 Study

BACKGROUND

The prevalence and burden of musculoskeletal (MSK) conditions are growing around the world, and low back pain (LBP) is the most significant of the five defined MSK disorders in the Global Burden of Disease (GBD) study. LBP has been the leading cause of non-fatal health loss for the last three decades. The objective of this study is to describe the current status and trends of the burden due to LBP in Brazil based on information drawn from the GBD 2017 study.

METHODS

We estimated prevalence and years lived with disability (YLDs) for LBP by Brazilian federative units, sex, age group, and age-standardized between 1990 and 2017 and conducted a decomposition analysis of changes in age- and sex-specific YLD rates attributable to total population growth and population ageing for the purpose of understanding the drivers of changes in LBP YLDs rates in Brazil. Furthermore, we analyzed the changes in disability-adjusted life years (DALYs) rankings for this disease over the period.

RESULTS

The results show high prevalence and burden of LBP in Brazil. LBP prevalence increased 26.83% (95% UI 23.08 to 30.41) from 1990 to 2017. This MSK condition represents the most important cause of YLDs in Brazil, where the increase in burden is mainly related to increase in population size and ageing. The LBP age-standardized YLDs rate are similar among Brazilian federative units. LBP ranks in the top three causes of DALYs in Brazil, even though it does not contribute to mortality.

CONCLUSIONS

Findings from this study show LBP to be the most important cause of YLDs and the 3rd leading cause of DALYs in Brazil. The Brazilian population is ageing, and the country has been experiencing a rapid epidemiological transition, which generates an increasing number of people who need chronic care. In this scenario, more attention should be paid to the burden of non-fatal health conditions.

Exercise-induced hypoalgesia after acute and regular exercise: experimental and clinical manifestations and possible mechanisms in individuals with and without pain

This review describes methodology used in the assessment of the manifestations of exercise-induced hypoalgesia in humans and previous findings in individuals with and without pain. Possible mechanisms and future directions are discussed.

Exercise and physical activity is recommended treatment for a wide range of chronic pain conditions. In addition to several well-documented effects on physical and mental health, 8 to 12 weeks of exercise therapy can induce clinically relevant reductions in pain. However, exercise can also induce hypoalgesia after as little as 1 session, which is commonly referred to as exercise-induced hypoalgesia (EIH). In this review, we give a brief introduction to the methodology used in the assessment of EIH in humans followed by an overview of the findings from previous experimental studies investigating the pain response after acute and regular exercise in pain-free individuals and in individuals with different chronic pain conditions. Finally, we discuss potential mechanisms underlying the change in pain after exercise in pain-free individuals and in individuals with different chronic pain conditions, and how this may have implications for clinical exercise prescription as well as for future studies on EIH.

Long-term effect of physical inactivity on thoracic and lumbar disc degeneration-an MRI-based analysis of 385 individuals from the general population

BACKGROUND CONTEXT

The correlation between physical inactivity, thoracolumbar disc degeneration, and back pain remains unclear.

PURPOSE

This study investigated the relationship between short- and long-term physical inactivity and degenerative changes of the thoracic and lumbar spine in a southern German cohort from the general population over a time period of 14 years.

STUDY DESIGN/SETTING

This study was designed as a cross-sectional case-control study, nested in a prospective cohort from the "Cooperative Health Research in the Region of Augsburg/Kooperative Gesundheitsforschung in der Region Augsburg" (KORA) study.

PATIENT SAMPLE

All participants in the population-based KORA study were assessed using a physical activity questionnaire to establish a baseline in 1999-2001 (exam 1), within an initial follow up questionnaire in 2006-2008 (exam 2), and a second follow-up questionnaire between 2013 and 2014 (exam 3). A subsample of this group (400 subjects) underwent full body MR scan performed on a 3T magnetic resonance imaging scanner current with exam 3.

OUTCOME MEASURE

Data regarding physical inactivity over a time period of 14 years and back pain, and quantification of thoracic and lumbar disc degeneration on magnetic resonance imaging.

METHODS

Quantification of thoracic and lumbar disc degeneration was performed using the Pfirrmann score. Physical activity was grouped as no physical activity, irregularly for 1 hour, regularly for 1 hour, or regularly for ≥2 hours. This was used to calculate another variable "physical inactivity," with the options of irregular activity ≤1 hour per week or regularly ≥1 hour. Physical labor, walking, and cycling activity were additionally investigated. Correlations between physical inactivity measurements and thoracic and lumbar disc degeneration were analyzed via linear regression models adjusted for age, sex, BMI, hypertension, diabetes, and back pain.

RESULTS

In total, 385 individuals (mean age: 56 years, SD ± 9.19; 58.2% male) were included in this study. Mean summed Pfirrmann score was 2.41 (SD ± 4.19) in the thoracic and 1.78 (SD ± 1.81) in the lumbar spine. The level of current exercise in our cohort varied with 113 (29.4%) subjects exercising regularly ≥2 hours per week, 118 (30.7%) regularly 1 hour per week, 57 (14%) irregularly for about 1 hour per week, and 97 (25.2%) stated not to exercise at exam 3. Disc degeneration was more apparent in those with irregular activity <1 hour compared to those with regular activity of ≥1 hour and more per week (p<.01) and in those with no activity compared to those with regular activity of ≥2 (p<.001) measured using exam 3. Less physical activity over a time period of 14 years correlated with an increase of disc degeneration of the thoracic and lumbar spine after adjustment for age, sex, BMI, hypertension and diabetes mellitus (p<.05). There was no statistically significant association between physical labor, walking activity, or cycling activity with disc degeneration. Additionally, no significant correlations between degree of disc degeneration (p=.990), degree of physical inactivity (p=.158), and back pain were observed.

CONCLUSION

Degree of physical inactivity as measured over a time period of 14 years demonstrated a strong correlation with disc degeneration of the thoracic and lumbar spine.
