BACKGROUND: Breast cancer surgeries affect the upper extremities and posture. This study aimed to examine the efficacy of muscle energy and Mulligan mobilization techniques on the upper extremities and posture after breast cancer surgery with axillary dissection. METHODS: A total of 90 female participants who had undergone breast cancer surgery with axillary dissection were recruited and randomly assigned to three groups. Group A received a combination of the Mulligan and muscle energy techniques, while Groups B and C received either the Mulligan or muscle energy techniques for six weeks, respectively. The study measured the shoulders' range of motion, posture, and upper-extremity disabilities. Outcome measurements were taken at three different time points: baseline, post-intervention, and at eight-week follow-up. RESULTS: All the interventions significantly improved the study outcomes. The combination of the Mulligan and muscle energy techniques was significantly better than a single intervention. Mulligan mobilization was superior to the muscle energy techniques in terms of improving the shoulders' range of motion and disability. The interventions showed a significant effect pre-post-treatment and pre-follow-up but not post-follow-up. CONCLUSIONS: The Mulligan mobilization and muscle energy techniques have been found beneficial in improving the postural changes and shoulder outcomes after breast cancer surgery with axillary dissection. The superior effectiveness of the combined interventions points out the importance of integrating multiple therapeutic approaches for optimal outcomes. Regular examination and long-term follow-up assessment are important for studying the effect of rehabilitation interventions in people after the late stages of breast surgery.
