Arm Lymphoedema, Shoulder Mobility and Muscle Strength after Breast Cancer Treatment ? A Prospective 2-year Study

Abstract

Arm lymphoedema and impaired shoulder mobility and muscle strength are well known side-effects to breast cancer treatment. The aim of this prospective study was to follow closely and describe the arm volume, range of motion of the shoulder and muscle strength of the shoulder and hand after breast cancer treatment in order to form a basis for further studies in the area including physiotherapy intervention. Sixty-one women treated for breast cancer with axillary dissection, with or without postoperative radiotherapy, were examined preoperatively and monthly until 6 months after the operation with 1- and 2-year follow-ups. 1 month after the operation, results revealed decrease in range of motion, after 2 months increase in arm volume difference and after the first 6 months decrease in muscle strength of shoulder adductors, flexors and internal rotators. A greater increase in arm volume difference and decrease in shoulder abduction, flexion and external rotation were noted throughout the follow-up period for...
