About this trial
This is a two-arm, controlled clinical trial with a parallel design. Participants will be randomly assigned to an intervention or control group. The study is single-blind, as outcome assessors will be blinded to group allocation, while participants and physiotherapists cannot be blinded due to the nature of the intervention. Consecutive sampling will be applied.
For the evaluation of intervention effects (primary and secondary outcomes), the study will follow the Consolidated Standards of Reporting Trials (CONSORT) for non-pharmacological interventions. For the assessment of satisfaction and adherence, a qualitative study will be conducted following the COREQ EQUATOR 17 guidelines to ensure methodological rigor.
The intervention will consist of a 12-week home-based exercise program supervised via mixed telerehabilitation (TR). The control group will perform the same program but receive only telephone follow-up. Four assessments will be conducted: baseline (T0), post-intervention (T1), three months follow-up (T2), and six months follow-up (T3).
