3. 1st Pilot-test Phase. Affected individual/caregiver dyads who consented will be invited to participate in the first pilot phase of 10 dyads. These subjects will participate in either Group 1 (initial intervention), which will participate first, or Group 2 (wait list control group). Group 1 will participate in the Paired PLIÉ program 2 times/week for 45 minutes for 4 weeks and then once/month for additional 3 months while Group 2 will be wait-listed. After Group 1 has completed their training, Group 2 will participate in the PLIÉ program 2 times/week for 45 minutes for 4 weeks and then once/month for additional 3 months. Group assignment will be random. Investigators will strive to have an equal distribution of men/women in the two groups.
