Efeito agudo da técnica de reeducação postural global na postura de mulheres com encurtamento da cadeia muscular anterior

INTRODUCTION: Global posture reeducation (GPR) is an evaluation and treatment method to several postural dysfunctions that use through global postures to treat alterations on muscular chains. OBJECTIVE: to analyze the effect of one session of GPR in the posture of women with shortened anterior muscular chain. METHODS: Thirty volunteers (20 ± 2.4 years) with shortened anterior chain were divided randomly in two groups: experimental group and control group. In the experimental group GPR was applied for 40 min, and in the control group, the participants were not submitted to any procedure. Eleven related variables were measured to analyze posture through photometry, before and immediately after GPR technique. RESULTS: The related variables to head and shoulder presented significant modifications as: the angle of head protrusion (p = 0.00), the heads horizontal alignment (p = 0.02), distance plum-line through ear (p = 0.00) and distance plumb-line through acromy (p = 0.00). CONCLUSION: GPR induced immediate effect in the heads and shoulder position; however a single intervention of GPR was not able to alter the positioning of other analyzed structures, as trunk, pelvis and inferior limb.

The Effects of a Perturbation-Based Balance Training on Neuromuscular Recruitment and Functional Mobility in Community-Dwelling Older Women: A Randomized Controlled Trial

The study aimed to evaluate a perturbation-based balance training program designed to target neuromuscular recruitment and functional mobility in older women. Older women were divided into exercise group (6-week balance training) and control group. Timed Up & Go test, central activation failure of ankle muscles, and electromyographic activity from 6 lower-limb muscles were assessed during postural perturbations. Variables were analyzed at baseline, at the 6-week follow-up, and after a detraining (6-week) period. The balance training improved electromyographic amplitude during postural perturbations, the central activation failure, and the Timed Up & Go test score. The perturbation-based balance training program improved muscle activation and the functional performance of older women.
