Blinding
Due to the nature of the intervention, participants and physical therapists cannot be blinded to group allocation. However, participants will be blinded to the expected outcomes, unaware of the study hypotheses, and will be explicitly instructed not to discuss their training program with the assessors to maintain assessor blinding. A trained assessor who is blinded to group allocation will be responsible for all outcome assessments. Data analysts and statisticians will also be blinded to group allocation.
