Constraint Induced Movement Therapy Increases Functionality and Quality of Life after Stroke

Abstract

This blind randomized clinical trial evaluated the effect of CIMT on the functionality and quality of life (QOL) of chronic hemiparetics. Thirty volunteers were divided into two groups: Control (CG) and CIMT (CIMTG); evaluated before and after 12 and 24 intervention sessions. The scales used were: adapted Fugl-Meyer Motor Assessment (FMA), Modified Ashworth, Stroke Specific Quality Of Life (SS-QOL) and the Functional Reach Test (FRT). The scores for all FMA variables in the CIMTG increased until the 24th session, differing from the pre-treatment. In the CG, the scores increased for pain, coordination/ speed and sensitivity. In the FRT there was an increase in the scores in both groups; after the 12th and 24th sessions, the result of the CIMTG was superior to the CG. For the SS-QOL in the CIMTG, the general score and most of the variables increased, as well as in the CG. Muscle tone in CIMTG was lower compared to CG after 24 sessions. Both protocols used in the study were effective, the CIMT protocol showed benefits in recovering the functionality of the paretic upper limb, in the functional range and in reducing muscle tone, with a consequent improvement in quality of life.
