Two forms of exercise were used in the group program, which recruited patients from a Parkinson's disease outreach program and took place in a community center heavily used by military families. The exercise sessions were 45 minutes long, three days a week.

For the first eight weeks, patients participated in a supervised open-floor series of exercises called ThinkBig, which stresses large extensions and movements of the arms and legs.

The Nintendo Wii video gaming system was used in the final four weeks, also encouraging participants to swing their arms and move vigorously.

Alvarez explained that these exercises are ideal for Parkinson's disease patients, whose condition often induces them to limit their range of motion.
