Objective: To compare response to upper limb treatment using robotics (ROB) + motor learning (ML) vs. functional electrical stimulation (FES) + ML vs. ML alone, according to a measure of complex functional everyday tasks for chronic, severely impaired stroke survivors.
Design: single-blind, randomized trial.
Setting: Clinical research lab, Medical Center.
Participants: 39 enrolled subjects, >1 year post single stroke (attrition rate=10%; 35 completed the study). No adverse effects.
Interventions: All groups received treatment 5 days/week, 5hrs/day (60 sessions), with unique treatment as follows: ML alone (n=11), 5hrs/day partial and whole task practice of complex functional tasks; ROB+ML (n=12), 3.5hrs/day ML and 1.5hrs/day shoulder/elbow robotics; FES+ML (n=12), 3.5hrs/day ML and 1.5hrs/day FES wrist/hand coordination training.
Main Outcome Measures: Primary measure: Arm Motor Ability Test (AMAT), 13 complex functional tasks; secondary measure: upper limb Fugl-Meyer coordination (FM).
Results: No significant difference found in treatment response across groups (AMAT (p≥.584) and FM (p≥.590)). All three treatment groups demonstrated clinically and statistically significant improvement in response to treatment (AMAT and FM, p≤.009). A group treatment paradigm of 1:3 (therapist:patient) ratio proved feasible for provision of the intensive treatment.
Conclusions: Severely impaired stroke survivors with persistent (>1yr) upper extremity dysfunction can make clinically and statistically significant gains in coordination and functional task performance, in response to ROB+ML, FES+ML, and ML alone, in an intensive and long-duration intervention, and no group difference was found. Additional study is warranted to determine the effectiveness of these methods in the clinical setting.
