Decreased upper limb function and low level of physical activity in breast cancer survivors: A case-control study

Abstract

This study aim to compare upper limb functionality, fatigue and physical activity level in women after breast cancer surgery in relation to a control group. Upper limb functionality was evaluated by mean of shoulder range of motion (ROM) of flexion, abduction and external rotation using a digital inclinometer; handgrip strength using a dynamometer and upper limb disability with the Disabilities of the arm, shoulder and hand questionnaire. Fatigue was assessed with the Brief Fatigue Inventory and physical activity level with the International Physical Activity Questionnaire. A thirty-four women (n=17, postoperated breast surgery group, PO; n=17, control group, CG) were recruited. PO group presented a decrease in both shoulder ROM and handgrip strength (range difference: 22.9°-22,9°; 5.6kgF, respectively) compared to CG; the affected side of the PO group presented with less shoulder ROM in comparison to the non-affected side (15°-21°). There was also greater disability on the affected side and a lower physical activity level in the PO group. There were no differences in the fatigue between the groups. We concluded that PO group presented with compromised functionality and low physical activity level compared to a control group.
