C. STUDY DESIGN AND METHODS Design A randomized controlled trial. Duration Following enrollment, study participants will remain on the study for 2.5 months after instruction in their individualized REST program. REST titration and tailoring for participant specific barriers will occur over the telephone for the 2 week "initiation phase" after initial REST instruction. Thereafter, patients will perform their REST independently at home during the 8 week "training phase" with "as needed" telephone-based guidance from a PT. We therefore anticipate that the study will continue for a total of 6 months; 3 months to recruit 68 patients and an additional 2.5 months for all participants to complete initiation and training phases of the protocol.
