Primary Outcome Measures

Name	Time	Method
It is expected that after 20 sessions of Transcutaneous Electrical Nerve Stimulation (TENS) to dysesthesia caused by nerve damage intercostobrachial (NICB) in women undergoing axillary lymphadenectomy is decreased.<br>Was used to calculate the sample based on previously published studies with methodological design and similar areas of study. Estimating a level of significance of 5% and a power of 75% was calculated sample size of approximately 15 subjects per group.;After 20 sessions of Transcutaneous Electrical Nerve Stimulation (TENS)the dysesthesia caused by intercostobrachial nerve (ICBN)injury decreased in women undergoing axillary lymphadenectomy.

Secondary Outcome Measures

Name	Time	Method
It is expected that the intensity of discomfort in the arm (measured by the Visual Analogue Scale-VAS) ipsilateral diminished significantly after 20 sessions of TENS in TENS group active.<br>And that skin sensitivity (assessed by esthesiometry) and pressure pain threshold (assessed by algometry) are changed after the intervention in the active TENS group.<br>The quality of life (assessed by the EORTC QLQ C30 and BR23) improves significantly after treatment in the active TENS group.;The intensity of discomfort in the arm (measured by the Visual Analogue Scale-VAS) ipsilateral decreased significantly after 20 sessions of TENS in TENS group active, but compared with the placebo TENS group, no difference was found.<br>Cutaneous sensitivity (assessed by esthesiometry) and pressure pain threshold (assessed by algometry) did not change after the intervention in either group.<br>The quality of life (as measured by the EORTC QLQ C30 and BR23) is not modified significantly after the treatment in both groups.<br><br>
