Overview
Brief Summary
The hemiparesis is one of the most important sequelae of stroke, and generally have greater impairment in the upper limb (UL) contralateral to the brain injury. To obtain greater amount of use and most affected UL movement quality, studies have described as a rehabilitation technique constraint Induced Therapy (CIT). The objectives of this study will evaluate the effect of CIT in severe hemiparetics patients in the quantity and quality of movement UL and grip strength, and the relation between the scapular kinematics and trunk with the quality of movement measured clinically. Randomized crossover study with systematic reviews in AB mode, where A is the baseline to the evaluation of the period of 2 weeks without any intervention and B, the two-week period with intervention. One group will start with the intervention period (BA) and the other group with the period without intervention (AB). The intervention will be for 3 hours / day, 5x / week for two weeks and use of wrist and fingers restriction UL unaffected. To evaluate the quality and quantity of UL use in real environment will be used to Motor Activity Log (MAL), to quantify the motor skill the Wolf Motor Function Test (WMFT), the 3D movement of the scapula and trunk during arm elevation and functional activities of the UL will be measured by the electromagnetic tracking system and grip strength by hand dynamometer.
Detailed Description
Randomized crossover study with systematic reviews in AB mode, where A is the baseline to the evaluation of the period of 2 weeks without any intervention and B, the two-week period with intervention, developed in the Evaluation Laboratory and complex intervention of shoulder at the Federal University of São Carlos (UFSCar). Patients will be divided into two groups through the online tool www.randomization.com. One group will start with the intervention period (BA) and the other group with the period without intervention (AB). As the evaluator will not know the distribution of patients in groups, will be blinded as to the pre and post intervention. The quantity variables, quality of movement, time to perform tasks and grip strength UL measures the MAL and WMFT, will be evaluated in five moments: at baseline, at the end of phase A, at the end of phase B, and monitoring of 1 and 3 months after the crossover period. The evaluation of scapular kinematics and trunk occur only at the beginning and the four-week period ends. Measures shall be performed by the principal investigator who is a physiotherapist who trained for Group Research Therapy Induced by restraining the University of Alabama at Birmingham in 2008, headed by Edward Taub (creator of the technique) and David Morris. The intervention will be carried out by three other physical therapists with the same training. Thus, the protocol will be based on the principles recommended by the Extremity Constraint-Induced Therapy Evaluation (EXCITE), a project that involved seven centers of North American research. The sample size is calculated for the main variables, quality movement measured by LAM. The effect size considered to be clinically relevant to the MAL is 1.0 on a scale from 0 to 5. The standard deviation of this variable in the population of severe hemiparesis found in other studies was. With a power of 80% and an α-probability error of 5% would require 16 patients in total.
