Computer-Based Rhythm and Timing Training in Severe, Stroke-Induced Arm Hemiparesis

Abstract

We pilot tested the efficacy of computer-based training implementing rhythm and timing in chronic, severe, stroke-induced hemiparesis. Two chronic stroke patients were administered the upper-extremity section of the Fugl-Meyer Impairment Scale (FM), the Arm Motor Ability Test (AMAT), Stroke Impact Scale (SIS), and Canadian Occupational Performance Measure (COPM). We then administered the computer-based intervention for 60 min, 3 days/wk for 4 wk. One week after intervention, we administered the FM, AMAT, COPM, and SIS. After intervention, participants exhibited reduced arm impairment (indicated by FM scores of + 2.0 and +4.0) and increases in average functional ability (+0.85 and +1.1 points on the AMAT), perceived quality of life (+2.0 and +32.0 points on the SIS), and perception of overall recovery (+10.0 points for each participant on the SIS). This study provides preliminary evidence suggesting efficacy of computer-based rhythm and timing in chronic stroke.
