Abstract The stroke is the second cause of death and the first of disabilities in the world. Although a motor spontaneous recovery is observed, around 50 to 70% of the hemiparetic upper extremity present alterations of upper extremity, limiting the performance of daily activities even after 2 to 4 years of strokes. More recently used in neurological rehabilitation, the ability to promote sensory-motor facilitation is given to the Elastic Tape (ET). However, its safety and efficacy in the treatment of post-stroke individuals still require further investigation. Thus, the objective of this project is to evaluate the immediate effects of ET, applied to the paretic shoulder on proprioception during movements of abduction and flexion of the shoulder and muscle activation and kinematic variables for the reaching in chronic hemiparetic and healthy subjects. Twenty subjects with chronic hemiparesis (HC) and twenty healthy subjects (C) matched for gender and age will participate in the study. HC and C groups will be divided into placebo, P, (HCP: n = 10; CP: n = 10) and BE (HCBE: n = 10; CBE: n = 10). The motor impairment of HC group and the dominance of C group will be evaluated by Fugl-Meyer scale and the Inventory Side dominance of Edinburgh, respectively. BE will apply deltoid (anterior, middle and posterior). Assessment before and after the application of ET will be performed. For the assessment of motor performance in a functional task (reach a glass of water), spatio-temporal parameters (total duration of the motion, peak velocity, time to peak velocity) and three-dimensional joint kinematics of the trunk, scapula, shoulder, elbow and wrist (total range of motion, joint angle maximum and minimum) will be used. Concomitantly, bilateral activation of the deltoid (anterior, middle and posterior), trapezius (upper and lower), serratus anterior and pectoral major will be assessed by electromyography during reach. The following electromyographic variables will be analyzed: activation amplitude, muscle onset and maximum and minimum activation. For statistical analysis, the normality and homogeneity tests will be applied. If the variables have a distribution considered normal and homogeneous, ANOVA Thre-way repeated measures gift will be applied. Otherwise it will be applied to non-parametric statistics Friedman. Will be considered a 0.05 significance level for all statistical tests. (AU) | |
