Forty subjects will complete multiple baseline testing and then be randomized, using random number table, to one of 4 groups: condensed functional task practice modeled after Constraint-Induced Movement Therapy (6 hours of practice/day, 5 days/week, 2 weeks), condensed functional task practice with a restricted number of tasks practiced, distributed, distributed functional task practice (Monday, Wednesday, Friday, 6 hours/session, 10 sessions), distributed functional task practice with a restricted number of tasks practiced. During therapy sessions, subjects will practice performing common activities with their paretic upper extremity. They will wear a mitt on their non-paretic upper extremity for up to 90% of their waking hours. Post-testing sessions will follow within one week of completing therapy with an additional follow-up testing session 3 months later.
