Dry Needling in Overhead Athletes with Myofascial Shoulder Pain: A Systematic Review

The treatment of myofascial pain in athletes requires a set of rehabilitation techniques that aim to be effective quickly. In this context, dry needling (DNY) has shown interesting results due to its ability to reduce pain in the short term. Thus, the aim of this study was to investigate the role of DNY in managing myofascial shoulder pain in overhead athletes. PubMed, Scopus and Web of Science were screened up to March 2024, to identify studies that met the following inclusion criteria: overhead athletes with shoulder pain with a DNY approach for myofascial trigger points (MTrPs), RCT, case-control study, feasibility study as the study design. Exclusion criteria were studies that did not include athletes, studies that did not focus on the treatment of MTrPs with DNY, other reviews, no full-text availability and papers written in a language other than English. Out of 399 articles, 165 were excluded as duplicates. Of the 234 articles screened, only 6 articles met the inclusion criteria. A total of 6 studies were included in the systematic review. Initial results showed that DNY improved pain rapidly and in the short term; however, there is still no consensus on the minimum number and the interval between treatments. Major findings reported a rapid potential decrease in perceived pain, shoulder disability and an increase in muscle strength; in this scenario, DNY might be a valid solution in a sports rehabilitation setting.

Effectiveness of low-level gallium aluminium arsenide laser therapy for temporomandibular disorder with myofascial pain: A systemic review and meta-analysis

PURPOSE

Temporomandibular disorder (TMD) causes masticatory muscle pain and mouth opening limitations and affects patients' ability to eat, practice oral health and perform other activities of daily living. Although the benefits of low-energy lasers in treating TMD have been reported, the results vary greatly depending on the equipment used and the energy output. This study systematically evaluated the efficacy of a low-level gallium aluminium arsenide (GaAlAs) laser treatment for TMD with myofascial pain and maxillary pain.

METHODS

We searched the PubMed, EMBASE, Cochrane Library, Web of Science, and ClinicalTrials.gov databases for randomized controlled trials (RCTs) published since database inception to April 5, 2020, that compared low-level laser treatment to sham/placebo treatment or no intervention in patients suffering from TMD with myofascial pain. Three reviewers independently screened the literature, extracted data, and assessed the quality of the included studies according to the risk-of-bias tool recommended by the Cochrane Handbook V.5.1.0 (Cochrane Collaboration, London, UK). Then, a meta-analysis was performed using RevMan 5.3 and Stata 15.1 software.

RESULTS

The data from 8 randomized controlled trials including 181 patients were analyzed. The severity of myofascial TMD pain (measured on a visual analogue scale, VAS) at the end of treatment was significantly different between the control laser therapy and the low-level GaAlAs laser therapy (weighted mean difference [WMD] = -0.76, 95% confidence interval [CI] -1.51 to 0.01, P = .046); at 3 to 4 weeks after treatment, there was no significant difference (WMD = 1.24, 95% CI -0.04 to 2.51, P = .057). In addition, there was no significant improvement in maximum mouth opening (MMO) at the end of treatment (WMD = -0.03, 95% CI -4.13 to 4.06, P = .987) or at 3 to 4 weeks after treatment (WMD = 1.22, 95% CI -2.94 to 5.39, P = .565).

CONCLUSIONS

The results of this study suggest that there is insufficient evidence to indicate an efficacy of low-level GaAlAs laser therapy in improving TMD pain and maximal oral opening. These results suggest that clinicians should make appropriate recommendations to inform patient decision-making.

Effect of Physical Exercise Programs on Myofascial Trigger Points-Related Dysfunctions: A Systematic Review and Meta-analysis

OBJECTIVE

Myofascial pain syndrome is one of the primary causes of health care visits. In recent years, physical exercise programs have been developed for the treatment of myofascial trigger points, but their effect on different outcomes has not been clarified. Thus, this study aimed to assess the effect of physical exercise programs on myofascial trigger points.

METHODS

A systematic search was conducted in Pubmed, Web of Science, and Scopus. Articles analyzing the effect of physical exercise programs on pain intensity, pressure pain threshold, range of motion, and disability were included. Risk of bias was assessed using the Cochrane RoB2 tool. The DerSimonian-Laird method was used to compute the pooled effect sizes (ES) and their 95% confidence interval (95% CI) for pain intensity, pressure pain threshold, range of motion, and disability.

RESULTS

A total of 24 randomized controlled trials were included in this systematic review and meta-analysis. The pooled ES were -0.47 (95% CI = -0.61 to -0.33) for pain intensity, 0.63 (95% CI = 0.31 to 0.95) for pressure pain threshold, 0.43 (95% CI = 0.24 to 0.62) for range of motion, and -0.18 (95% CI = -0.45 to 0.10) for disability.

CONCLUSIONS

Physical exercise programs may be an effective approach in the treatment of pain intensity, pressure pain threshold, and range of motion among patients with myofascial trigger points.

A Systematic Review of Golf Warm-ups: Behaviors, Injury, and Performance

Ehlert, A and Wilson, PB. A systematic review of golf warm-ups: behaviors, injury, and performance. J Strength Cond Res 33(12): 3444-3462, 2019-Previous literature has demonstrated that warm-ups have the potential to increase physical performance and reduce risk of injury. Warm-ups before golf may have a similar result, but a systematic evaluation of their effects in golf is currently lacking. Three electronic databases (PubMed, SPORTDiscus, and Web of Science) were systematically searched to address 3 primary research questions: (a) What are the current warm-up behaviors of golfers?; (b) Is there an association between warm-up behaviors and golf-related injury?; and (c) What are the effects of various warm-up protocols on measures of golf performance? Twenty-three studies (9 observational and 14 experimental) were identified that included data on warm-ups before golf participation. Overall, the current data suggest that many golfers either do not warm-up regularly or perform a warm-up that is short in duration. Studies on the association between warm-up behaviors and golf-related injury were mixed and inconclusive. Experimental studies suggest that a variety of warm-up methods may be beneficial for golf performance. Specifically, dynamic warm-ups and those with resistance exercise tended to enhance measures of performance, whereas static stretching was inferior to other methods and potentially detrimental to performance. Overall, the results of this systematic review suggest that various warm-up protocols (with the exception of static stretching) may enhance golf performance, but observational data suggest many golfers do not regularly perform them. More data are needed on the warm-up behaviors of competitive golfers, the impact of warm-up behaviors on golf-related injury, and to further identify effective warm-up methods for enhancing golf performance.
