Comparing complementary alternative treatment for chronic shoulder pain of myofascial origin: Collateral meridian therapy versus local tender area-related meridians therapy

Alternative therapies in chronic non-cancer pain management: A scoping review of randomized controlled trials

BACKGROUND

Chronic pain is one of the most challenging health problems in modern society, placing significant burdens on individuals and healthcare systems. While pharmacological treatments remain the primary approach to pain management, their limitations often restrict choices for both clinicians and patients. In contrast, complementary therapies are gaining recognition for their potential effectiveness and safety. However, the current literature lacks a comprehensive summary of the role of complementary therapies in chronic pain management.

OBJECTIVE

This review aims to summarize the complementary therapies used in chronic non-cancer pain management, assess their practical applications, identify research gaps and limitations, and provide a comprehensive perspective for the development of chronic non-cancer pain management and personalized pain management strategies.

METHODS

This scoping review followed the PRISMA-ScR guidelines. Randomized controlled trials (RCTs) published in the last decade were retrieved from PubMed and Web of Science using the keywords "chronic pain" and "complementary therapy." Non-English studies were excluded.

RESULTS

A total of 848 RCTs were identified, of which 128 met the inclusion criteria. The included studies addressed chronic musculoskeletal pain (102 studies), chronic visceral pain (5 studies), chronic neuropathic pain (7 studies), and 13 studies that did not specify the pain type. The complementary therapies investigated included acupuncture, manual therapy, exercise therapy, psychological interventions, mind-body therapies, and physical modalities.

CONCLUSION

This review provides preliminary evidence supporting the efficacy and safety of complementary therapies in the management of chronic non-cancer pain. However, methodological and quality-related limitations were identified in the included studies. Future high-quality RCTs are needed to validate the long-term efficacy of these therapies, explore their mechanisms of action, and provide stronger evidence for their clinical application.

Exercise Therapy and Electrotherapy as an Intervention for Primary Dysmenorrhea: A Systematic Review and Meta-Analysis

Primary Dysmenorrhea (PD) is characterized by painful cramps before or during menstruation. It is generally treated with nonpharmacological methods. However, with the advancement of research and the passage of time, physiotherapy plays an increasingly important role in treating patients with PD. Electrotherapy and exercise therapy are conservative methods to treat PD. Alternative methods to minimize reliance on medicinal-based treatments are the need of the hour. This review aims to determine the efficacy of exercise-based therapies and electrotherapy modalities in treating PD. Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards have been used in the present systematic review and meta-analysis. Cochrane, PubMed, and Google Scholar were searched to facilitate the same. The articles from 2011 to 2021 were included in this review. The quality of the review was assessed using the Cochrane risk of bias tool. The visual analog scale was taken as a measure of pain intensity in the meta-analysis, and other outcomes have been included in the systematic review discussed. A total of 15 publications have been included, with a meta-analysis of 7. All included studies were of high quality (PEDro ≥ 5), and demonstrated the efficacy of exercise-based therapies and electrotherapy modalities in treating pain in females with PD. This review aims to check the impact of exercise and electrotherapy in females suffering from PD.

Noninvasive management of soft tissue disorders of the shoulder: A clinical practice guideline from the Ontario Protocol for Traffic Injury Management (OPTIMa) collaboration

OBJECTIVES

Objective of this study is to develop an evidence-based guideline for the noninvasive management of soft tissue disorders of the shoulder (shoulder pain), excluding major pathology.

METHODS

This guideline is based on high-quality evidence from seven systematic reviews. Multidisciplinary experts considered the evidence of effectiveness, safety, cost-effectiveness, societal and ethical values, and patient experiences when formulating recommendations. Target audience is clinicians; target population is adults with shoulder pain.

RESULTS

When managing patients with shoulder pain, clinicians should (a) rule out major structural or other pathologies as the cause of shoulder pain and reassure patients about the benign and self-limited nature of most soft tissue shoulder pain; (b) develop a care plan in partnership with the patient; (c) for shoulder pain of any duration, consider low-level laser therapy; multimodal care (heat/cold, joint mobilization, and range of motion exercise); cervicothoracic spine manipulation and mobilization for shoulder pain when associated pain or restricted movement of the cervicothoracic spine; or thoracic spine manipulation; (d) for shoulder pain >3-month duration, consider stretching and/or strengthening exercises; laser acupuncture; or general physician care (information, advice, and pharmacological pain management if necessary); (e) for shoulder pain with calcific tendinitis on imaging, consider shock-wave therapy; (f) for shoulder pain of any duration, do not offer ultrasound; taping; interferential current therapy; diacutaneous fibrolysis; soft tissue massage; or cervicothoracic spine manipulation and mobilization as an adjunct to exercise (i.e., range of motion, strengthening and stretching exercise) for pain between the neck and the elbow at rest or during movement of the arm; (g) for shoulder pain >3-month duration, do not offer shock-wave therapy; and (h) should reassess the patient's status at each visit for worsening of symptoms or new physical, mental, or psychological symptoms, or satisfactory recovery.

CONCLUSIONS

Our evidence-based guideline provides recommendations for non-invasive management of shoulder pain. The impact of the guideline in clinical practice requires further evaluation.

SIGNIFICANCE

Shoulder pain of any duration can be effectively treated with laser therapy, multimodal care (i.e., heat/cold, joint mobilization, range of motion exercise), or cervicothoracic manipulation and mobilization. Shoulder pain (>3 months) can be effectively treated with exercises, laser acupuncture, or general physician care (information, advice, and pharmacological pain management if necessary).

Acupuncture for pain, mandibular function and oral health-related quality of life in patients with masticatory myofascial pain: A randomised controlled trial

BACKGROUND

Masticatory myofascial pain is the most prevalent muscular temporomandibular disorders (TMD). It primarily affects masseter and temporal muscles. Several treatments, including acupuncture, have been recommended. However, systematic reviews have highlighted gaps in studies and absence of conclusive results.

OBJECTIVES

We performed a randomised controlled clinical trial to evaluate the effectiveness of acupuncture in improving pain, mandibular function and oral health-related quality of life in women with masticatory myofascial pain.

METHODS

Thirty-six patients diagnosed with masticatory myofascial pain according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) were divided into the following two groups: acupuncture and control (non-penetrating acupuncture).Treatment was performed weekly for 5 weeks, and pain, mandibular function and oral health-related quality of life were evaluated one week before treatment, one week after treatment and one month after treatment. Non-parametric and parametric tests were used for comparisons between times and treatment groups (significance level of P ≤ .05).

RESULTS

The acupuncture group showed a significant reduction in pain (P ≤ .01), which was not observed in the control group. Pain intensity was reduced by 61% and 84% at 1 week and 1 month after treatment, respectively. Both groups showed significant improvements in mandibular function and oral health-related quality of life over time (P ≤ .01). Statistical analysis did not show a significant difference between the groups for any other evaluated outcome (P > .05).

CONCLUSION

Although acupuncture was effective in pain reduction, non-specific factors may have influenced mandibular function and oral health-related quality of life improvements in both groups, and this needs to be further addressed.

Meridian Cuffing Exercises Improved Functional Fitness and Cardiopulmonary Functioning of Community Older Adults

This study was aimed to test the effects of a meridian cuffing exercise, the Healthy Beat Acupunch (HBA) regimen, on the functional fitness and cardiopulmonary functioning of community older adults. A single-blind, cluster randomized controlled trial was conducted. We randomly allocated eight community care centers to the intervention or control group and recruited 228 participants who completed the study (intervention: four centers, n = 111; control: four centers, n = 117). The intervention group underwent a 40-min session of HBA regimen 3 times per week for 6 months. Functional fitness and cardiopulmonary functioning were assessed at baseline, 3 months, and 6 months of the intervention. The intervention group demonstrated significantly greater improvements in functional fitness and cardiopulmonary functioning than the control group between baseline and either 3 months or 6 months. We suggest that activities designed to promote health among community older adults include acupunch exercises.

Effect of transcutaneous electrical nerve stimulation therapy for the treatment of primary dysmenorrheal

BACKGROUND

This study aimed to investigate the effect and safety of transcutaneous electrical nerve stimulation (TENS) therapy for relieving pain in women with primary dysmenorrhea (PD).

METHODS

In this study, 134 participants with PD were randomly divided into the intervention group and the sham group, with 67 participants in each group. Participants in the intervention group received TENS, whereas those in the sham group received sham TENS. The primary outcome was measured by the Numeric Rating Scale (NRS). The secondary outcomes were measured by the duration of relief from dysmenorrheal pain, number of ibuprofen tablets taken, and the World Health Organization quality of life (WHOQOL)-BREF score, as well as the adverse events.

RESULTS

A total of 122 participants completed the study. Compared to sham TENS, TENS showed a greater effect in pain relief with regard to the NRS (P < .01), duration of relief from dysmenorrheal pain (P < .01), and number of ibuprofen tablets taken (P < .01). However, no significant differences in the quality of life, measured by the WHOQOL-BREF score, were found between 2 groups. The adverse event profiles were also similar between 2 groups.

CONCLUSION

TENS was efficacious and safe in relieving pain in participants with PD.
