Following a stroke, or cerebral vascular accident (CVA), restoring function to the involved arm or leg becomes a huge priority. Physiologically, spasticity will decrease within 15-20 minutes of immersion into a heated pool. Aquatic physical therapy will take advantage of this to stretch then strengthen involved muscles with a variety of techniques and positions. Weight bearing through the weak arm and leg has been shown to help normalize tone, and is accomplished easily in the aquatic environment. Walking is practiced in a supportive environment with less fatigue and greater endurance for activity.
