This study evaluates the effectiveness of automated FES-assisted exercise therapy in improving motor function of the upper extremity in people with hemiplegia. Six subjects with stroke-induced hemiplegia used an automated workstation with instrumented objects to perform a set of tasks with their affected hand during one-hour sessions for 12 days. We used functional electrical stimulation for assistance with hand opening. The workstation sensors provided kinematic data to a desktop computer. Motor function of the affected upper extremity was further assessed by an investigator, blinded to the exercise protocol, using the Fugl-Meyer Test (FMT) and the Wolf Motor Function Test (WMFT). A Motor Activity Log (MAL) was used to assess home use of the affected extremity. The short-term efficacy of the therapy was reported at the 2001 SfN meeting. Kinematic data showed that improvement in upper extremity motor function immediately after the therapy was retained at the 2-months follow-up. However, the amount of improvement was decreased on average by 40% for two out of three practised tasks, and increased by 60% for the third task. WMFT and MAL showed an increase in the amount of improvement at the follow-up by 90% and 35% respectively in comparison to the post-treatment improvement. FMT showed no changes after the therapy. We conclude that automated FES-assisted exercise therapy results in long-term improvement of motor function of hemiplegic upper extremity and that the improvement continues to increase after the therapy. Results from an ongoing study on acute stroke patients will also be presented.
