Objective. Compare the efficacy of low-frequency low-intensity magnetotherapy and fluxtuorization of the shoulder belt and upper limb muscles on the side of surgical intervention in combination with therapeutic exercise and balance therapy, classes in a medical psychologist in patients for 2—4 days and 1.5—2 months after the radical mastectomy. Material and methods. A total of 131 patients aged 25 to 70 years were examined and treated after a radical mastectomy for breast cancer. The 1st group included 76 patients who were rehabilitated on the 2nd—4th day after radical mastectomy, the 2nd group included 55 women who were rehabilitated after 1.5—2 months. Results and conclusion. It has been established that the early onset of medical rehabilitation in patients after radical mastectomy (on the 2nd—4th day after surgical intervention) contributed to the reduction of pain syndrome and postoperative edema, increase of movements in shoulder joint, prevention of severe lymphostasis and improvement of life quality. The contribution of low-frequency low-intensity magnetotherapy to the complex of rehabilitation measures is, above all, to reduce swelling and reduce blood viscosity. Fluctuating currents promote restoration of volume of movements on the party of operative intervention, namely — support functional activity of muscles and joints of the top extremity that allows to restore a motor stereotype.
