Abstract:
Objective
To investigate the effects of myofascial release technique on shoulder joint function and quality of life in patients after radical mastectomy for breast cancer.
Methods
A prospective analysis was conducted on 82 breast cancer patients who underwent radical mastectomy in the Xindu District Hospital of Traditional Chinese Medicine, Chengdu, from October 2021 to February 2023. Patients were randomly divided into a control group and an observation group (41 cases each) using a random number table method. The control group received manual lymphatic drainage postoperatively, while the observation group received myofascial release therapy. Shoulder joint flexion, extension, internal rotation, and external rotation angles, as well as Visual Analogue Scale (VAS) scores, were measured before treatment, immediately after treatment, and one month after treatment. Repeated measures ANOVA was used for intergroup comparisons.The Patient Health Questionnaire-9 (PHQ-9), Disabilities of the Arm, Shoulder and Hand (DASH) scale,and Functional Assessment of Cancer Therapy-Breast (FACT-B) scores were assessed before treatment, after treatment, and one month after treatment, with intergroup comparisons performed using t-tests.
Results
The observation group showed significantly lower VAS scores than the control group (between-group: F=17.869,P<0.001; time effect: F=105.517,P<0.001;interaction: F=32.303,P<0.001). Shoulder joint mobility(flexion, extension, internal rotation, and external rotation angles) was significantly better in the observation group (flexion: between-group: F=5.636, P=0.020; time effect: F=33.024, P<0.001; interaction: F=7.635, P=0.007; extension angle: between-group: F=8.829, P=0.004; time effect: F=197.515, P<0.001; interaction F=23.266, P<0.001; internal rotation angle: between-group: F=5.409, P=0.023; time effect: F=73.649, P<0.001; interaction effect: F=24.294, P<0.001; external rotation angle: betweengroup: F=7.970, P=0.006; time effect: F=84.163,P<0.001; interaction: F=14.369,P<0.001). The scores of the PHQ-9 and the DASH in the observation group were significantly lower than those in the control group (t=5.937,P< 0.001;t=3.034,P=0.003), and the score of the FACT-B scale was significantly higher than that of the control group (t=3.166,P=0.002).
Conclusion
Myofascial release therapy improves overall shoulder mobility, reduces pain and depressive symptoms, and enhances quality of life in post-mastectomy patients, demonstrating promising clinical efficacy and application potential.
