Brief Summary

This study evaluates the comparative effectiveness of a multi-modal facility-based rehabilitation program (therapist-led resistance exercise and relaxation training) versus a self-directed home-based resistance exercise program in post-treatment breast cancer survivors. Participants in both intervention groups will complete a 16-week program consisting of two exercise sessions per week.The multimodal, therapist-led approach is hypothesized to result in superior improvements in physical performance and quality of life outcomes compared to self-directed home exercise

Outcome Measures

Primary Outcomes (1)

  • Change from Baseline in Skeletal Muscle Mass Index (SMI)

    Skeletal Muscle Mass Index (SMI) is calculated by dividing total skeletal muscle mass (kg), as measured by bioelectrical impedance analysis (ACCUNIQ BC720; SELVAS Healthcare), by the square of the height (m²). Higher scores indicate greater muscle mass relative to height (better outcome).

  • Functional Battery: Change from Baseline in 4-Meter Gait Speed

Facility-Based Resistance and Relaxation

EXPERIMENTAL

Participants engage in a 16-week multimodal rehabilitation program at Taipei Tzu Chi Hospital. The intervention is comprised of one weekly therapist-led session and one weekly self-directed home session (totaling two sessions per week) involving elastic band resistance exercise and relaxation training

Behavioral: Multimodal Resistance and Relaxation Training

Home-Based Resistance Exercise

ACTIVE COMPARATOR

Participants perform a 16-week self-directed elastic band resistance exercise program. The intervention consists of two weekly home-based sessions using elastic bands, performed without therapist supervision.

Behavioral: Home-Based Resistance Exercise Training

Interventions

A 16-week multimodal program consisting of resistance exercise and relaxation training. Participants undergo two sessions per week: one weekly session is conducted under the supervision of a physical therapist at Taipei Tzu Chi Hospital, and one weekly session is self-directed and performed by the participant in a home setting. The resistance exercise portion utilizes progressive elastic band training

Facility-Based Resistance and Relaxation

A 16-week self-directed resistance exercise program. The intervention consists of two sessions per week performed independently by the participant in a home setting. The exercise regimen utilizes progressive elastic band training and is conducted without direct therapist supervision

Home-Based Resistance Exercise
