Post Stroke Hand Functions: Bilateral Movements and Electrical Stimulation Treatments

Participants practice moving their paretic arm at the same time as they move their non-paretic arm in the same movement patterns. Neuromuscular electrical stimulation triggered by the participants' own contracting muscles is provided to the paretic arm during the movements. Training period was 4 times per week for 2 weeks.

Participants practice moving both their paretic and non-paretic arms at the same time in the same movement patterns. Neuromuscular electrical stimulation triggered by the participants' own contracting muscles is provided to the paretic arm during the movements. Training period was 2 times per week for 2 weeks.

Participants practice moving both their paretic and non-paretic arms at the same time in the same movement patterns. Sham electrical stimulation (low level electrical stimulation that can be felt but is insufficient to trigger a muscle contraction) is provided to the paretic arm during the movement. Training period was 2 times per week for 2 weeks.
