Participants will receive an 8-week tele-rehabilitation program consisting of supervised aerobic and resistance exercise sessions delivered remotely three times per week. The program will be individualized and progressively adjusted based on participant tolerance and clinical status.

Participants will continue receiving standard clinical care without participation in the tele-rehabilitation program during the study period.

An 8-week tele-rehabilitation program consisting of supervised aerobic and resistance exercise sessions delivered remotely three times per week using video communication. The program includes individualized exercise prescription and progressive adjustment based on participant tolerance and clinical status. Sessions are conducted by trained rehabilitation personnel following established pulmonary rehabilitation guidelines.

Fat-free mass index (FFMI) will be used as the primary measure of muscle mass. FFMI will be assessed using body composition analysis and expressed as fat-free mass divided by height squared (kg/m²), with higher values indicating greater muscle mass."

Frailty will be assessed using the FRAIL scale, a validated screening tool evaluating fatigue, resistance, ambulation, illnesses, and weight loss. The outcome measure is the total FRAIL scale score (range: 0 to 5), with higher scores indicating greater frailty.

Patient satisfaction will be assessed using the Telehealth Usability Questionnaire (TUQ), a validated tool evaluating usefulness, ease of use, interface quality, interaction quality, reliability, and satisfaction. The outcome measure is the total TUQ score, with each item rated on a 5-point Likert scale (1 = strongly disagree to 5 = strongly agree). Higher scores indicate greater satisfaction with the tele-rehabilitation program.
