Purpose：The purpose of this study was to examine the effect of upper extremity exercise and Bandage on the edema and range of motion. Complex decongestive physiotherapy was one of the latest methods to deal with the limitation of range of motion and the edema that were the prime problems of patients with lymphedema. Methods：Twenty patients undergone mastectomy were participated in this study voluntarily. They had lymphedema on upper extremity and partial limitation of range of motion. The subjects had been treated with upper extremity home exercise and complex decongestive physiotherapy with Bandage for 4 weeks. The measure of these patients with upper extremity edema was included: the volume, arm circumfenence and range of motion. These were measured two times: before the treatment, after 4 weeks of the treatment. Results：The upper extremity edema of patients treated home exercise group and complex decongestive physiotherapy group with Bandage was definitely decreased (p<0.05). Moreover, the upper volume of those who were the same condition also significantly shrank and patients` arm circumferences of upper arm breathtakingly diminished as well (p<0.05). But home exercise group patients` arm circumferences of forearm was not remarkable (p>0.05). However, patients` range of motion who were treated with upper extremity exercise were evidently increased when compared to that of the before treatment (p<0.05). Conclusion：Complex decongestive physiotherapy and bandage performed by physical therapist increased the ROM of upper arm and reduced the edema in patients with lymphedema.
