Acupuncture for Low Back Pain: An Overview of Systematic Reviews

Objective. As evidence of the effectiveness of acupuncture for low back pain (LBP) is inconsistent, we aimed to critically appraise the evidence from relevant systematic reviews. Methods. Systematic reviews of randomized controlled trials (RCTs) concerning acupuncture and LBP were searched in seven databases. Internal validity and external validity of systematic reviews were assessed. Systematic reviews were categorized and high quality reviews assigned greater weightings. Conclusions were generated from a narrative synthesis of the outcomes of subgroup comparisons. Results. Sixteen systematic reviews were appraised. Overall, the methodological quality was low and external validity weak. For acute LBP, evidence that acupuncture has a more favorable effect than sham acupuncture in relieving pain was inconsistent; it had a similar effect on improving function. For chronic LBP, evidence consistently demonstrated that acupuncture provides short-term clinically relevant benefits for pain relief and functional improvement compared with no treatment or acupuncture plus another conventional intervention. Conclusion. Systematic reviews of variable quality showed that acupuncture, either used in isolation or as an adjunct to conventional therapy, provides short-term improvements in pain and function for chronic LBP. More efforts are needed to improve both internal and external validity of systematic reviews and RCTs in this area.

Low level laser therapy (Photobiomodulation therapy) for breast cancer-related lymphedema: a systematic review

BackgroundBreast cancer related lymphedema (BCRL) is a prevalent complication secondary to cancer treatments which significantly impacts the physical and psychological health of breast cancer survivors. Previous research shows increasing use of low level laser therapy (LLLT), now commonly referred to as photobiomodulation (PBM) therapy, for BCRL. This systematic review evaluated the effectiveness of LLLT (PBM) in the management of BCRL.MethodsClinical trials were searched in PubMed, AMED, Web of Science, and China National Knowledge Infrastructure up to November 2016. Two reviewers independently assessed the methodological quality and adequacy of LLLT (PBM) in these clinical trials. Primary outcome measures were limb circumference/volume, and secondary outcomes included pain intensity and range of motion. Because data were clinically heterogeneous, best evidence synthesis was performed.ResultsEleven clinical trials were identified, of which seven randomized controlled trials (RCTs) were chosen for analysis. Overall, the methodological quality of included RCTs was high, whereas the reporting of treatment parameters was poor. Results indicated that there is strong evidence (three high quality trials) showing LLLT (PBM) was more effective than sham treatment for limb circumference/volume reduction at a short-term follow-up. There is moderate evidence (one high quality trial) indicating that LLLT (PBM) was more effective than sham laser for short-term pain relief, and limited evidence (one low quality trial) that LLLT (PBM) was more effective than no treatment for decreasing limb swelling at short-term follow-up.ConclusionsBased upon the current systematic review, LLLT (PBM) may be considered an effective treatment approach for women with BCRL. Due to the limited numbers of published trials available, there is a clear need for well-designed high-quality trials in this area. The optimal treatment parameters for clinical application have yet to be elucidated.

Traditional Chinese Medicine acupuncture and myofascial trigger needling: The same stimulation points?

BACKGROUND Acupuncture originates in China, and its effectiveness has been well documented in musculoskeletal pain disorders and other conditions. A widely accepted contemporary medical treatment option for myofascial pain is trigger point needling. Although there are many differences between Traditional Chinese Medicine acupuncture theory and the myofascial trigger point needling framework, it is argued that the stimulation sites for these two needling modalities are similar. DISCUSSION In this paper we examined the correspondence between Traditional Chinese Medicine acupoints and myofascial trigger points. Based on this correspondence, we considered exploration of Ah-shi points from four aspects: pain recognition, distal Ah-shi points, Anti-Ah-shi points, and management approaches. SUMMARY The extent of correspondence is influenced by definitions of acupoints. Myofascial trigger points are significantly correlated to Traditional Chinese Medicine acupoints, including primary channel acupoints, extra acupoints, and Ah-shi points. Considering the correlation between MTrPs and acupoints and the rarely-studied research area of Ah-shi points, it may be reasonable to incorporate research findings of myofascial trigger points into further investigations into Ah-shi points. Correspondence between myofascial trigger points and acupoints enhances contemporary understanding of the mechanism of action of acupuncture, and may serve to facilitate increased integration of acupuncture into clinical management.

STRICTA: is it time to do more?

BackgroundIn order to facilitate the completeness and transparency of reporting on randomized controlled trials undertaken using acupuncture interventions, a consensus group of international experts developed the Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA) in 2002. This reporting guideline was updated in 2010, and was applicable to a broader range of acupuncture research, including uncontrolled trials and case reports. Subsequent evaluations have noted limitations on the impact of STRICTA in the reporting quality of acupuncture trials, and the description of acupuncture details remains poor. Thus improvement in the efficacy of the STRICTA guidelines is called for.DiscussionWe explored the STRICTA guidelines from four aspects, including the development procedure, validity assessment, endorsement and adherence, and citation situation. Based upon these findings, we provided five potential suggestions for further development of STRICTA.SummarySTRICTA are valid reporting guidelines based on robust methodology and scientific content. However specific implementation strategies including: updating the STRICTA checklist; improving the STRICTA reporting efficiency; consistency with implementing the “Instructions for authors” for journals; establishing global STRICTA research centers; and expanding the STRICTA website, are needed. Such strategies will improve their utilization and impact positively on the quality of reporting on acupuncture research outcomes.

The Influence of Age, Sex and Body Mass Index on the Effectiveness of Brisk Walking for Obesity Management in Adults: A Systematic Review and Meta-Analysis

BACKGROUND Brisk walking is the most popular activity for obesity management for adults. We aimed to identify whether participant age, sex and body mass index (BMI) influenced the effectiveness of brisk walking. METHODS A search of 9 databases was conducted for randomized controlled trials (RCTs). Two investigators selected RCTs reporting on change in body weight, BMI, waist circumference, fat mass, fat-free mass, and body fat percentage following a brisk walking intervention in obese adults. RESULTS Of the 5072 studies screened, 22 met the eligibility criteria. The pooled mean differences were: weight loss, -2.13 kg; BMI, -0.96 kg/m2; waist circumference, -2.83 cm; fat mass, -2.59 kg; fat-free mass, 0.29 kg; and body fat percentage, -1.38%. Meta-regression of baseline BMI showed no effect on changes. CONCLUSIONS Brisk walking can create a clinically significant reduction in body weight, BMI, waist circumference, and fat mass for obese men and women aged under 50 years. Obese women aged over 50 years can achieve modest losses, but gains in fat-free mass reduce overall change in body weight. Further research is required for men aged over 50 years and on the influence of BMI for all ages and sexes.

Does the dose of Traditional Chinese Medicine acupuncture in addition to usual care affect outcomes for adults with chronic low back pain? Protocol for a randomized controlled feasibility study

Abstract Background: Acupuncture is considered a clinically effective and cost-effective treatment option for chronic low back pain. However, few clinical trials have evaluated the dose dependence of acupuncture for chronic low back pain based on the number of sessions. Conclusions are conflicting and there is little high-quality evidence to support the cumulative effects of repeated interventions. A randomized controlled trial to investigate the optimal number of sessions of acupuncture in addition to usual care for adults with chronic low back pain is required; a feasibility study to test the rationale and method for the full-scale trial is the first step in that process. Design: A pragmatic parallel three-armed randomized, controlled feasibility study. Methods: Forty-five participants with chronic low back pain will be recruited locally and randomized on a 1:1:1 basis to receive usual care plus 4 (n = 15), 7 (n = 15) or 10 sessions (n = 15) of semi-standardized acupuncture. Primary outcomes are acceptability of and adherence to different numbers of sessions of acupuncture, as well as the feasibility of the recruitment approach and completion of the specific outcome measures. Secondary outcomes include pain intensity and patient satisfaction. Follow-up questionnaires will be collected at discharge, 6, and 12 weeks after randomization. Discussion: Outcomes will inform the decision to conduct a full-scale trial to definitively test the dose dependence of acupuncture. Findings will add to the limited evidence available regarding the optimal number of sessions of acupuncture in the management of chronic low back pain, as well as being clinically relevant to clinicians, researchers and policy makers.

Low level laser therapy in the management of breast cancer-related lymphedema: protocol for a randomized controlled feasibility trial

Abstract Background: Breast cancer-related lymphedema (BCRL) is a prevalent long-term condition secondary to cancer treatment. BCRL impacts physical function, psychological health, and quality of life for patients who have survived breast cancer. Objectives: This study will assess the feasibility of a fully-powered randomized controlled trial investigating the effectiveness of low level laser therapy (LLLT), also known as photobiomodulation (PBM) therapy, as an adjunct treatment for managing BCRL. Methods: This study will be a pragmatic two-armed randomized controlled feasibility trial. Twenty female participants being treated for BCRL at the Dunedin Hospital, New Zealand, will be recruited over a 6-month window. Subject to informed consent, participants will be offered LLLT (PBM) in addition to their regular treatment for BCRL. Twelve treatments with laser therapy will continue for 6 weeks (twice weekly). Feasibility outcomes (recruitment rate, randomization rate, participant’s adherence to the LLLT (PBM) treatment protocol, and participant retention rates) will be collected during the recruitment and intervention period. Participant satisfaction will be collected on completion of treatment intervention. Safety outcomes of LLLT (PBM) will be collected at each treatment visit. Clinical outcome measures (limb circumference, participant’s perceived symptoms, psychological impacts, and activity disability) will be assessed at baseline, 6 and 12 weeks post-randomization. Conclusions: Results of this feasibility trial will inform the design and implementation of a future definitive randomized controlled trial, which will investigate the effectiveness of LLLT (PBM) for women with BCRL.

Low level laser therapy for the management of breast cancer-related lymphedema: A randomized controlled feasibility study: LASER THERAPY FOR BREAST CANCER RELATED-LYMPHEDEMA

This study aimed to determine the feasibility of conducting a full scale randomized controlled trial investigating the effectiveness of low level laser therapy (LLLT), also known as photobiomodulation (PBM) therapy, used in addition to conventional therapy, for managing breast cancer related lymphedema (BCRL).

Low level laser therapy (photobiomodulation) for the management of breast cancer-related lymphedema: an update

Breast cancer related lymphedema (BCRL) is prevalent among breast cancer survivors, and may be painful and disfiguring with associated psychological impact. Previous research shows increasing use of low level laser therapy (LLLT), now commonly referred to as photobiomodulation (PBM) therapy for managing BCRL, in countries including the United States and Australia. However, conclusions were limited by the paucity, heterogeneity, and poor quality of previous studies. LLLT (PBM) has been barely used in clinical practice in New Zealand, and no clinical studies on LLLT (PBM) for BCRL have been conducted in this country. In order to promote this potentially useful treatment modality for BCRL patients, the Laser Lymphedema Trial Team at the University of Otago conducted a program to assess the effectiveness of LLLT (PBM) in management of BCRL. The program comprises three phases including a systematic review (completed), a feasibility study (completed), and a full-scale randomized controlled trial (proposed). This current paper provides an update on the program. Based upon the systematic review, LLLT (PBM) is considered a potentially effective treatment approach for women with BCRL; the review also indicated the need for further research including exploration of the relevance of dosage and other LLLT (PBM) parameters. The feasibility study demonstrated that it is feasible to conduct a fully powered RCT to definitively test the effectiveness of the additional use of LLLT (PBM) in the management of BCRL, and 114 participants will be needed at baseline in the main study. Currently, the full-scale RCT is under preparation.

Acupuncture for chronic low back pain: a randomized controlled feasibility trial comparing treatment session numbers:

Objective: To evaluate the feasibility of a randomized controlled trial investigating the optimal number of treatment sessions of acupuncture, used as an adjunct to usual care, for managing chronic low back pain. Methods: In total, 45 participants with chronic low back pain were recruited and randomly allocated to receive usual care plus 4, 7, or 10 sessions of acupuncture (15/group). Primary outcomes were recruitment rate, randomization rate, treatment compliance, completion of the outcome measures, and retention rates. Secondary outcomes included back function, pain intensity and bothersomeness, generic health status, activity disability, and participant satisfaction. Data were collected at baseline and discharge, and at 6 and 12 weeks post randomization. Results: The recruitment method was demonstrated to be successful: recruitment rate was 43.7%, and randomization rate was 100%. Compliance with treatment was high among participants (86.7%, 86.7%, and 100% for the 4-, 7-, and 10-session group, respectively). Outcome questionnaires used in this study were found to be appropriate for a future randomized controlled trial. Participant retention rates were 88.9% at discharge and at 6 weeks post randomization and 84.4% at 12 weeks post randomization. Secondary outcomes (except for pain intensity) favored the 10-session acupuncture group at 12 weeks post randomization. Over 90% of participants indicated that they were “very satisfied” and/or “extremely satisfied” with the acupuncture treatment. Conclusion: This study demonstrated that a full-scale randomized controlled trial using the methodology described above is feasible, and such a trial is essential to test the dose dependence of acupuncture.
