Reduction in handgrip strength and electromyographic activity in women with breast cancer.

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.
