Prevention of Post-Stroke Hand/Wrist Flexion Deformity

"BION™ Experimental Group~The goal for the BION™ patients is to achieve 30 minutes of stimulation twice daily, using a cycled stimulation at frequencies adequate to produce tetanic contraction, (typically 25-35 pps) that raises the joint through full range of motion against gravity (a range graded as 3/5) based on the available range of motion.~Surface Stimulation Group~Patients will be instructed to stimulate twice daily for 30 minutes through surface electrodes placed according to instructions that the subject has been given. Every effort will be made to ensure that the parameters needed in this group are chosen to produce a similar type of contraction to that obtained with BION™ stimulation.~Control Group with conservative therapy (Range of motion exercises)~The research participant is instructed in self-administered, standard range of motion stretching exercises."
