Effects of core stability training on older women with low back pain: a randomized controlled trial

On-Site Physiotherapy in Emergency Department Patients Presenting with Nonspecific Low Back Pain: A Randomized Controlled Trial

Background: There is a high incidence of nonspecific Low Back Pain (LBP) in patients visiting Emergency Departments (EDs), but there is a lack of knowledge regarding emergency physiotherapy for LBP. The effect of on-site physiotherapy in these patients was therefore never demonstrated. We assessed short-term outcomes, feasibility and patient satisfaction with physiotherapy in ED patients presenting with nonspecific LBP. Methods: A block-randomized, controlled, open-label trial with a follow-up of 42 days. Patients aged 18 years or older presenting to an ED with nonspecific LBP were prospectively enrolled. Both groups received the same booklet with written information on LBP management and exercises. Patients in the intervention group were given additional instructions by a certified physiotherapist. Results: We included 86 patients in the primary analysis. The median age was 40, and 40.7% were female. At day 7, the median Oswestry Disability Index (ODI) was 2 points lower in the intervention group compared to the control group, which was not statistically significant. There was no between-group difference in pain at day 7. Patients who received physiotherapy felt significantly more confident with the exercises they were taught (p = 0.004, effect size = 0.3 [95% CI 0.1 to 0.5]). Conclusions: On-site physiotherapy in ED patients presenting with nonspecific low back pain is associated with higher patient satisfaction, compared to standard of care. The effect of physiotherapy was small, with only minimal improvement in disability, but without a reduction in pain. Despite the very small effect size, physiotherapeutic interventions should be investigated in larger cohorts with an extended intervention including patient education, exercises, and other physiotherapeutic modalities.

The effectiveness, acceptability, and sustainability of non-pharmacological interventions for chronic pain management in older adults in mainland China: A systematic review

OBJECTIVES

This systematic review aims to assess the effectiveness, acceptability, and sustainability of non-pharmacological pain management interventions for older adults in mainland China.

MATERIALS AND METHODS

Articles searching was conducted across six databases, including MEDLINE, PubMed, PsycINFO, Web of Science, China National Knowledge Infrastructure (CNKI), and WanFangdata. Quality appraisal was performed using the revised Cochrane risk of bias tool.

RESULTS

A total of 26 articles met the inclusion criteria, involving 2,197 participants with a mean age of 69.19 years. The participants' ages ranged from 63.85 to 81.75 years. The evaluated non-pharmacological interventions included psychotherapy, acupuncture, exercise, massage, neurotherapy, and multidisciplinary interventions. The overall changes in pain intensity varied from -5.19 to -0.65 on a numeric rating scale ranging from zero to ten.

CONCLUSIONS

Non-pharmacological interventions proved effective in alleviating pain intensity among older adults in mainland China. The findings suggest that mindfulness, exercise and pain education can be promoted as viable strategies for enhancing the well-being of the elderly population.

The effects of dance interventions on physical function and quality of life among middle-aged and older adults: A systematic review

BACKGROUND

Fundamental physical functions such as postural control and balance are vital in preserving everyday life, affecting an individual's quality of life. Dance is a physical activity that offers health advantages across various life stages. Nevertheless, the effects of dance interventions on physical function, postural control, and quality of life among older adults have remained underexplored. The review aimed to examine the strength of evidence for dance interventions on physical function and quality of life among middle-aged and older adults.

METHODS

A systematic review was conducted across four databases (PubMed, Cochrane Library, Web of Science, and Medline), focusing on studies involving more than four weeks of dance interventions. MeSH terms [dance or dance intervention or dance rehabilitation or dance movement] and [motor function or functional capacity or postural control or functional mobility or mobility or postural balance or balance or flexibility or gait] and [well-being or quality of life or life satisfaction] were utilized in the search. This review was registered in the PROSPERO database (CRD42023422857). Included studies were assessed using the Cochrane Risk of Bias.

RESULTS

The search revealed 885 studies, and 16 met the inclusion criteria. The effects of various dance genres on physical functions and quality of life were compared. Most studies showed that dance intervention improved physical function, balance, postural control and quality of life. Dance intervention showed a high level of adherence compared to physiotherapy, self-care, conventional therapy, and aerobic and resistance exercise.

CONCLUSION

In terms of improving physical function and quality of life, structured dance is a safe and relatively effective alternative to exercise. Note the effect of movement selection and intensity in the dance interventions. Dance with music may increase participants' interest, encouraging more physical activity among middle-aged and older adults.

Isometric vs Isotonic Core Stabilization Exercises to Improve Pain and Disability in Patients with Non-specific Chronic Low Back Pain: A Randomized Controlled Trial

Background

Non-specific chronic low back pain (NSCLBP) is a prevalent condition that affects 90% of individuals experiencing low back pain. Core stabilization exercises (CSE) stand out as the most commonly employed therapeutic approach for managing NSCLBP. Nevertheless, there remains uncertainty regarding the superior effectiveness between isometric (ISOM) and isotonic (ISOT) types of CSE in the treatment of NSCLBP.

Objectives

The primary objective of this study was to compare the efficacy of ISOM and ISOT exercises concerning pain and disability in patients with NSCLBP. Additionally, the study aimed to assess the effectiveness of both ISOM and ISOT in comparison to no intervention concerning these variables in these patients.

Methods

This study was a randomized controlled trial that involved 41 men and women experiencing NSCLBP. Participants were randomly allocated to three groups: ISOM CSE (n = 13), ISOT CSE (n = 14), and a waitlist control (n = 14). The exercise training was administered for 40 - 60 minutes three times a week over a period of up to 8 weeks. Pain (assessed using the Visual Analog Scale or VAS) and disability (evaluated through the Oswestry Disability Index or ODI) variables were measured before and after the interventions.

Results

Based on the results, there was no significant difference between the 2 exercise groups (ISOM and ISOT) regarding pain and disability. However, the ISOM group demonstrated numerically better results than the ISOT group. Both the ISOM and ISOT groups exhibited a significant decrease in pain levels, with the VAS score decreasing from 5.5 to 2.7 for ISOM and from 5.8 to 3.7 for ISOT, as compared to the control group (P < 0.001 and P = 0.001, respectively). Additionally, the average disability showed a significant improvement in both the ISOM (ODI score from 17 to 11) and ISOT (ODI score from 15.4 to 11) groups compared to the control group (P < 0.001).

Conclusions

Both ISOM and ISOT methods are effective in alleviating pain and disability in patients with NSCLBP. However, there is no significant difference in the benefits between them. Numerically, ISOM exercises were found to be superior. Further studies are needed to obtain a more accurate answer regarding their superiority.

How to tackle non-specific low back pain among adult patients? A systematic review with a meta-analysis to compare four interventions

OBJECTIVE

To tackle non-specific low back pain (NSLBP) among patients and find the most effective solution and to quantitatively synthesize the overall effect of motor control training (MCT) compared with Pilates, McKenzie method, and physical therapy (PT) in pain and physical function.

METHODS

Randomized controlled trials (RCTs) of four types of intervention (MCT, Pilates, McKenzie method, and PT) for LBP were collected by searching PubMed, Web of Science, EBSCOhost (Cochrane Central Register of Controlled Trials), and Scopus databases from the establishment of the database to September 30, 2023. The risk of bias was evaluated for included studies using the Revised Cochrane Risk of Bias tool for randomized trials (RoB 2.0). Taking pain and physical function in the experimental and control groups as outcome indicators, subgroup analysis was performed according to the intervention method to calculate the standardized mean difference (SMD) and 95% confidence interval (CI).

RESULTS

A total of 25 RCTs, including 1253 patients, were included. Meta-analysis showed that MCT effectively relieved pain [SMD = -0.65, 95% CI (- 1.00, - 0.29), p < 0.01] and improved physical function [SMD = -0.76, 95% CI (- 1.22, - 0.31), p < 0.01] comparing with other 3 types of intervention. Subgroup analysis suggested that MCT could alleviate pain [SMD = -0.92, 95% CI (- 1.34, - 0.50), p < 0.01] and improve physical function [SMD = -1.15, 95% CI (- 1.72, - 0.57), p < 0.01] compared with PT, but it had no statistical significance compared with Pilates [pain: SMD = 0.13, 95% CI (- 0.56, 0.83), p = 0.71; physical function: SMD = 0.10, 95% CI (- 0.72, 0.91), p = 0.81] and the McKenzie method [pain: SMD = -0.03, 95% CI (- 0.75, 0.68), p = 0.93; physical function: SMD = -0.03, 95% CI (- 1.00, 0.94), p = 0.95].

CONCLUSIONS

MCT can effectively relieve pain and improve physical function in patients with NSLBP. It is more effective compared with PT for LBP, while no differences were detected between MCT and Pilates, as well as McKenzie method. Therefore, MCT, Pilates, and the McKenzie method should be encouraged as exercise interventions for NSLBP rehabilitation.

Systematic Review to Inform a World Health Organization (WHO) Clinical Practice Guideline: Benefits and Harms of Structured Exercise Programs for Chronic Primary Low Back Pain in Adults

PURPOSE

Evaluate benefits and harms of structured exercise programs for chronic primary low back pain (CPLBP) in adults to inform a World Health Organization (WHO) standard clinical guideline.

METHODS

We searched for randomized controlled trials (RCTs) in electronic databases (inception to 17 May 2022). Eligible RCTs targeted structured exercise programs compared to placebo/sham, usual care, or no intervention (including comparison interventions where the attributable effect of exercise could be isolated). We extracted outcomes, appraised risk of bias, conducted meta-analyses where appropriate, and assessed certainty of evidence using GRADE.

RESULTS

We screened 2503 records (after initial screening through Cochrane RCT Classifier and Cochrane Crowd) and 398 full text RCTs. Thirteen RCTs rated with overall low or unclear risk of bias were synthesized. Assessing individual exercise types (predominantly very low certainty evidence), pain reduction was associated with aerobic exercise and Pilates vs. no intervention, and motor control exercise vs. sham. Improved function was associated with mixed exercise vs. usual care, and Pilates vs. no intervention. Temporary increased minor pain was associated with mixed exercise vs. no intervention, and yoga vs. usual care. Little to no difference was found for other comparisons and outcomes. When pooling exercise types, exercise vs. no intervention probably reduces pain in adults (8 RCTs, SMD = - 0.33, 95% CI - 0.58 to - 0.08) and functional limitations in adults and older adults (8 RCTs, SMD = - 0.31, 95% CI - 0.57 to - 0.05) (moderate certainty evidence).

CONCLUSIONS

With moderate certainty, structured exercise programs probably reduce pain and functional limitations in adults and older people with CPLBP.

Effectiveness of pharmacological and non-pharmacological therapy on pain intensity and disability in older people with chronic nonspecific low back pain: a systematic review with meta-analysis

BACKGROUND AND PURPOSE

The aim of the present systematic review was to investigate the effectiveness of pharmacological and non-pharmacological therapy on pain intensity and disability in older people with chronic nonspecific low back pain.

METHODS

Searches were conducted in the MEDLINE, COCHRANE LIBRARY, EMBASE, AMED, PSYCINFO, and PEDRO databases up to 2022. Risk of bias was appraised using the Cochrane Risk of Bias 2.0 tool. Estimated mean differences and respective 95% confidence intervals were presented for each paired comparison and the strength of the current evidence was assessed using the GRADE approach.

RESULTS AND DISCUSSION

Thirty-one original trials involving 2120 participants were included. All outcomes were self-rated. Pain intensity was measured using the Visual Analogue Scale or Numerical Rating Scale. Disability was evaluated using the Roland Morris Disability Questionnaire, Oswestry Disability Index or Hannover Functional Ability Questionnaire. Short-term: Moderate quality of evidence that mindfulness reduces disability compared to patient education (mean difference [MD] =  - 1.38 [95% CI - 2.02 to - 0.73]); low-quality evidence that mixed exercise (MD = - 50.33 [95% CI - 57.11 to - 43.56]) reduces pain compared to no intervention, waiting list, placebo or sham; low quality of evidence that there is no effect for opioid compared to placebo (MD = - 8.26 [95% CI - 19.29 to 2.77]) with regards to reducing pain and opioid/acetaminophen reduces disability more compared to pregabalin (MD = 2.36 [95% CI] 1.86-2.86]).

CONCLUSIONS

The findings showed low or very low quality of evidence for non-pharmacological interventions with a large effect in short- and long-term follow-up. The two studies that provided moderate quality of evidence had a small clinical effect. Only two studies were found that investigated pharmacological therapies-both with low quality of evidence. However, the studies were methodologically weak and had small sample sizes. Given the adverse effects of low back pain and the scarce information on the effectiveness of pharmacological and non-pharmacological treatments for older people, future randomized trials should be encouraged.

Effects of exercise therapy on disability, mobility, and quality of life in the elderly with chronic low back pain: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Exercise is an effective treatment in chronic low back pain (CLBP), but there are few studies on CLBP in the elderly, and the intervention effect is controversial. We aimed to compare the efficacy of different exercises therapy on CLBP, dysfunction, quality of life, and mobility in the elderly.

METHODS

We searched Web of Science, MEDLINE, Cochrane Library, Chinese National Knowledge Infrastructure, EMBASE, and PubMed from the database inception till December 31, 2022. The publication languages were Chinese and English. Randomized controlled trials (RCTs) of exercise intervention in the elderly (≥ 60 years) with CLBP were included. Two reviewers independently extracted the data and evaluated them using the Revised Cochrane Risk of Bias Tool for Randomized Trials 2 (RoB2). The pooled effect sizes on different aspects of outcome measures were calculated.

RESULTS

Sixteen articles (18 RCTs) were included, comprising a total of 989 participants. The quality of included studies was relatively high. Meta-analysis results indicated that exercise therapy could improve visual analog scale (VAS) (WMD = - 1.75, 95% CI - 2.59, - 0.92, p < 0.05), Oswestry disability index (ODI) (WMD = - 9.42, 95% CI - 15.04, - 3.79, p < 0,005), short-form 36-item health survey physical composite summary (SF-36PCS) (WMD = 7.07, 95% CI 1.01, 13.14, p < 0.05), short-form 36-item health survey mental composite summary (SF-36MCS) (WMD = 7.88, 95% CI 0.09, 15.67, p < 0.05), and timed up and go test (TUG) (WMD = - 0.92, 95% CI - 2.22, 0.38, p < 0.005).

CONCLUSION

Exercise therapy effectively improved VAS, ODI, and SF-36 indexes in the elderly. Based on the subgroup, when designing the exercise therapy regimen, aerobics, strength, and mind-body exercise (≥ 12 weeks, ≥ 3 times/week, ≥ 60 min) should be considered carefully, to ensure the safety and effectiveness for the rehabilitation of CLBP patients. More high-quality trials are needed in future to confirm the effect of exercise on SF-36 and TUG indexes.

Efficacy and safety of extracorporeal shock wave on low back pain: A systematic review and meta-analysis

BACKGROUND

Extracorporeal shock wave therapy (ESWT) is a relatively new type of treatment for many musculoskeletal disorders. However, ESWT for low back pain remains controversial as the pain relieve benefit is questionable. We performed this systematic review and meta-analysis to explore the effectiveness and safety of ESWT interventions on pain and disability in patients with low back pain (LBP).

METHODS

In this meta-analysis, we searched electronic databases in the Pubmed, Embase, Cochrane's library, China National Knowledge Infrastructure, and Wanfang Database to determine the equivalence of ESWT and placebo for the treatment of LBP up to April 4, 2022. A number of other outcomes were measured, including functional status, quality of life, and psychological outcomes measured by the Oswestry Disability Index. Weighted mean differences were calculated for continuous outcomes, while risk ratios were calculated for binary outcomes. Stata 12.0 software was used for statistical analysis.

RESULTS

Thirteen randomized controlled trials included for further analysis. Compared with control, the ESWT group showed lower pain intensity at month 1 (P < .05), as well as lower disability score at month 1 (P < .05) and at month 3 (P < .05). There was no statistically significant difference between ESWT and control groups in terms of the pain intensity at month 3 (P > .05). No serious adverse events related to treatment were reported. Sensitivity analysis demonstrates that the conclusions from this analysis were robust.

CONCLUSIONS

ESWT is effective in alleviating pain and improving the functional outcomes for patients with LBP. However, there remains a lack of high-level evidence to verify their effectiveness and safety and support their clinical application.
