For the 40 week Maintenance Phase, yoga participants will be re-randomized in a 1:1 ratio to either a structured ongoing maintenance yoga program or no maintenance yoga program. Similarly, physical therapy participants will be re-randomized in a 1:1 ratio to either a structured ongoing maintenance PT program or no maintenance PT program. Education participants will be encouraged to continue to review and follow the recommendations of their educational materials. We hypothesize: (1) maintenance yoga will be non-inferior to maintenance PT; (2) maintenance yoga and maintenance PT will be superior to no yoga maintenance and no PT maintenance, respectively; and (3) maintenance yoga and maintenance PT will both be superior to education.
