Effectiveness of Circuit-Based Exercises on Gait Speed, Balance, and Functional Mobility in People Affected by Stroke: A Meta-Analysis.

BACKGROUND: Several interventions have been proposed to rehabilitate patients with neurologic dysfunctions due to stroke. However, the effectiveness of circuit-based exercises according to its actual definition, ie, an overall program to improve strength, stamina, balance or functioning, was not provided. OBJECTIVE: To examine the effectiveness of circuit-based exercise in the treatment of people affected by stroke. METHODS: A search through PubMed, Embase, Cochrane Library, and Physiotherapy Evidence Database databases was performed to identify controlled clinical trials without language or date restriction. The overall mean difference with 95% confidence interval was calculated for all outcomes. Two independent reviewers assessed the risk of bias. RESULTS: Eleven studies met the inclusion criteria, and 8 presented suitable data to perform a meta-analysis. Quantitative analysis showed that circuit-based exercise was more effective than conventional intervention on gait speed (mean difference of 0.11 m/s) and circuit-based exercise was not significantly more effective than conventional intervention on balance and functional mobility. CONCLUSION: Our results demonstrated that circuit-based exercise presents better effects on gait when compared with conventional intervention and that its effects on balance and functional mobility were not better than conventional interventions. LEVEL OF EVIDENCE: I.

Comparison of the mechanical properties of therapeutic elastic tapes used in sports and clinical practice.

STUDY DESIGN: Cross-sectional laboratory study. OBJECTIVE: The aim of the present study was to evaluate and compare the mechanical properties of different therapeutic elastic tapes used in sports and clinical practice. BACKGROUND: Therapeutic tapes have been used since around the 1800s. They are composed of cotton, elastic filaments and adhesive glue that provides an effect of tactile and mechanical stimulation. However, as taping has evolved, manufacturers have implemented new materials and claim that the tensile properties and adhesion of tapes contribute more significantly in the rehabilitation process. METHODS: Fifty samples of elastic tapes (5 different manufacturers; 10 samples from each manufacturer) were submitted to longitudinal traction until rupture as well as surface adherence assays. Information was recorded on maximum deformation, maximum load, maximum tension and relative stiffness. RESULTS: In tensile testing the bandages brand Kinesio Tex Gold - FP® showed higher rates, 3 in 4 properties. During surface adherence tests on the therapeutic elastic tapes the brand Premium Kinesiology 3 NS Tex® showed higher rates, 3 in 4 properties analyzed. CONCLUSIONS: Tapes from different manufacturers exhibit different characteristics regarding traction and adherence mechanics. Knowledge of these characteristics is fundamental for the optimized use of each tape based on specific therapeutic needs.
