Data Collection Patient-Reported Outcome (PRO) Measures. Baseline PROs will be collected after subjects sign informed consent, following randomization and, for intervention group members, before the PTs instruct them in the REST exercises. Week 10 PROs will be mailed to the patients with a postage paid return envelope. Participants who do not respond in the first week will be sent a second mailing. Subjects will receive $25.00 compensation for completing each set of PROs, for a total of $50.00.
