Abstract
Purpose: This study investigated the effects of a serial home-based exercise program in the affected upper extremity immediately after latissimus dorsi (LD) flap reconstruction with mastectomy in order to improve the functional impairment and quality of life in breast cancer survivors. Methods: Patients with breast cancer scheduled for a mastectomy immediately followed by autologous LD flap reconstruction surgery were enrolled. Forty-five patients were included as an intervention group who received a serial home-based exercise program with stretching and strengthening for upper extremities preoperatively (T0), and 2 weeks (T1), 6 weeks (T2), and 3 months (T3) postoperatively. Thirty-five patients were included as the control group. We evaluated the range of movement in the shoulder at T0, T1, T2, T3, 6 months (T4), and 12 months (T5) postoperatively. We also evaluated the disability of the upper extremity using disabilities of the arm, shoulder, and hand (DASH) questionnaire and quality of life using the 36-Item Short-Form Health Survey (SF-36) at T0, T3, T4, and T5. Results: There were significant differences in interaction effects between time and shoulder flexion and internal and external rotation. Post hoc, the intervention group showed more improvement of movement in internal rotation at T2 and T5 and external rotation at T2, T3, and T4. Furthermore, there were significant differences in interaction effects between DASH scores and time in the two groups. Post hoc, there were significantly lower DASH scores at T3, T4, and T5 in the intervention group. There were significant differences in interaction effects of physical role functioning, vitality, and mental health scores of SF-36 and time in the two groups. Post hoc, physical role functioning scores at T3 and T4 and vitality and mental health scores at T3 were elevated in the intervention group. Conclusion: A serial home-based exercise after LD flap reconstruction is effective for the rehabilitation of the affected upper extremity and enhances the quality of life.
