Content reporting and effectiveness of therapeutic exercise in the management of massive rotator cuff tears: A systematic review with 490 patients

Critical Appraisal of Clinical Trials Evaluating Physical Therapy Treatments for Temporomandibular Disorders: A Scoping Review

BACKGROUND

Physical therapy seems the most promising treatment for temporomandibular disorders (TMD), although their effectiveness is controversial in general, due to high heterogeneity regarding study designs, applied treatments and outcomes measures.

OBJECTIVES

The aim of this scoping review is to analyse the methodological characteristics of clinical trials evaluating physical therapy treatments in subjects with TMD.

METHODS

A systematic search was conducted in Medline/PubMed, SPORTDiscus, Scopus, Web of Science, SciELO, Cochrane, ScienceDirect and EMBASE databases on 31 October 2023. Clinical trials evaluating physical therapy interventions in patients older than 18 years with TMD, published in English or Spanish languages. Data regarding content reporting of study designs, sample characteristics, interventions and outcome measures was extracted. Descriptive summary statistics were reported.

RESULTS

The search retrieved 15 322 records, and 136 were included. There were 107 randomised clinical trials, 5 non-randomised controlled trials and 24 non-controlled trials. Most studies had moderate to high risk of bias, small sample sizes (median, 44 subjects) and short follow-up periods (1-3 months). The most common diagnostic criteria used was the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) (48.9%). The most reported experimental interventions were manual therapy (40.4%), exercise (30.2%) and electrotherapy modalities (27.2%), and the most common outcome measure domains were pain (83.8%), range of movement (61.8%), disability (45.6%) and mechanosensitivity (29.4%). There was poor content reporting of experimental interventions.

CONCLUSIONS

Current literature of clinical trials of physical therapy interventions for TMD has moderate to high risk of bias, poor content reporting, small sample size and short-term follow-ups which limit internal and external validity, as well as applicability into clinical practice.

A scoping review of tendon transfer surgeries and postsurgical physical therapy interventions in individuals with massive rotator cuff tears

OBJECTIVE

To identify tendon transfer surgeries and postsurgical physical therapy interventions in people with massive rotator cuff (RC) tears.

METHODS

The literature search was conducted in the MEDLINE, Science Direct, Scopus, Web of Science, and PEDro databases from inception to September 2022. Studies with patients diagnosed with massive RC tears undergoing tendon transfers that reported physical therapy interventions after surgery were included. Two reviewers pooled the data into ad hoc summary tables with the following information: authors, year, study characteristics (sample size, tendon transfer surgical used, approach type, preoperative risk, deficit addressed, additional surgical interventions), and physical therapy interventions (early stage, intermediate stage, and advanced stage).

RESULTS

Forty-four articles (59.0% case series) were included, with a total sample of 1213 participants. The most frequently used surgery was the isolated tendon transfer of the latissimus dorsi (49.1%). Most of the studies reported three main stages of physical therapy interventions after tendon transfer surgery: early stage (lasting 5-6 weeks), intermediate stage (started at 7-12 weeks), and advanced stage (started at 12 weeks). Physical therapy interventions included passive, active-assisted, resisted therapeutic exercise, and hydrotherapy.

CONCLUSIONS

The evidence regarding physical therapy interventions after RC tendon transfer surgery is limited to the number and duration of the stages and general characteristics without specifying the type and dose of the interventions. Future research with high methodological quality should integrate more detailed rehabilitation protocols to better guide therapeutic decisions after RC transfer surgery.
