Effects of Constraint-induced Therapy for the Scapular Kinematics in Patients With Severe Chronic Hemiparesis

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.

Constraint Induced Therapy

They will be instructed to remain with the mitt in UL less affected by 90% of the hours in which to stay awake beyond the training period. The training will consist of 30 minutes for the transfer package, interview by items of MAL, and 2 hours and 30 minutes with four tasks of Shaping, and Task Practice. The Transfer Package consists of a compromise agreement, held at the end of the first day of practice, in which the individual undertakes to complete: The Shaping is a training method that makes it difficult gradually according to the motor capacity of each individual. It will be taken care of including tasks using all joints (shoulder, elbow, wrist and fingers), giving priority to the individual in need. The individual will be instructed not to remove the trunk of the chair, and each task is repeated 10 times in no more than 45s. The Task Practice promotes increased motor function during functional activities. For all individuals will be held the same function: meal.

Control

This group has no intervention. They will wear a mitt that don't limit the use of the fingers and wrist. This is only to ensure blinding of the measurer
