Abstract: BACKGROUND:Breast cancer survivors have side effects from surgical treatment and adjuvant that may acutely or chronically compromise the musculoskeletal system, resulting in loss of muscle strength. OBJECTIVE: Handgrip strength and electromyography of the upper limbs and its relationship with dominance in women submitted to surgery for breast cancer. METHODS: Were evaluated 28 women. The handgrip strength was measured through dynamometer associated with electromyographic, in the muscles: descending trapezius, biceps brachial, triceps brachial, extensor carpi ulnaris, radial extensor carpi and superficial flexor of wrist and fingers. RESULTS: Reduction in grip strength on the side affected by the surgery, that occurred when the surgery was performed on the non-dominant side. The electromyographic showed significant differences in affected side. This shows the need to consider the affected side by surgery and dominance. CONCLUSIONS: Decreased grip strength and lower electromyographic activity of upper limb affected by surgery for breast cancer, when the side affected was not the dominant this loss was greater.
