Combining Electrical Stimulation and a Dynamic Hand Orthosis for Functional Recovery in Chronic Stroke
In Brief
A clinical study evaluating Electrical stimulation-dynamic hand orthosis for Stroke. Completed, enrolled 4 participants across 1 site.
Detailed Summary
Objective: To explore the effectiveness of a combined neuromuscular electrical stimulation (ES) and dynamic hand orthosis (DHO) regimen used with a small group of persons with chronic stroke in improving ability to perform daily tasks. Method: Four participants with chronic stroke participated in the combined ES-DHO regimen using the affected upper extremity (UE) five times (5X) per week for 6 weeks. Outcome measures included grip strength, range of motion (ROM), and analysis of muscle activation/deactivation during release of grasp through electromyography (EMG). Ability to perform daily functional tasks was assessed using the Assessment of Motor and Process Skills (AMPS). Results: Preliminary results suggest that improvements in strength, ROM and grasp deactivation are possible with the combined ES-DHO regimen. Ability to perform daily functional tasks improved in all participants. Conclusion: Results should be interpreted cautiously due to the pilot nature of the study and small participant number. Further research in this area is warranted.

Timeline
Interventions
Each participant participated in the electrical stimulation-dynamic hand orthosis regimen. Repetitive grasp/release motions were performed for 30 minutes while wearing the dynamic hand orthosis. This was followed by 15 minutes of electrical stimulation applied to forearm extensor muscles. This regimen was performed daily, 5X/week for 6 weeks.
