Effects of Electrical Stimulation on Blood Circulation and Sensibility Tactil in Lymphadenectomy

Not Applicable

• Conditions: Breast Cancer
• Interventions: Procedure: High voltage electrical stimulation - ( healthy women ); Procedure: high voltage electrical stimulation - axillary lymphadenectomy; Device: Neurodyn High Volt Model (IBRAMED)

• Registration Number: NCT01893957
• Lead Sponsor: University of Sao Paulo

Brief Summary

The aim of this study is to investigate the influence of electrical stimulation at the speed of blood circulation and tactile sensitivity of the arms of women who underwent axillary dissection for breast cancer.

Detailed Description

Introduction: the surgical treatment of breast cancer, especially axillary lymphadenectomy (AL), can cause blood circulatory changes, also partial or total lesion of the sensory nerve intercostobrachial, often causing anesthesia or hypoesthesia in the corresponding dermatome ipsilateral upper limb surgery. Objective: to investigate the influence of high voltage electrical stimulation (HVES) in the in the blood flow and tactile sensitivity in nerve path intercostobrachial of women undergoing AL. Methodology: sample of 30 volunteers, aged between 40 and 60 years, divided into two equal groups (n = 15): women with axillary dissection for breast cancer undergoing therapeutic procedure (GAL) and control group (CG) composed of women who did not undergoing axillary surgery. The treatment procedure consist of the application of high voltage electrical simulation for 30 minutes in both limbs twice a week over the course of seven weeks. The profile of blood flow, including speed, direction were evaluated by means of continuous wave Doppler ultrasound. The assessment of tactile sensitivity was accomplished through esthesiometer in three stages: before the start of the first therapeutic procedure, after completion of the intervention and 30 days after the end of treatment (wash-out). The data will be analyzed using descriptive statistics (ANOVA) even as the hypothesis testing of Shapiro-Wilk and if the data are not normally distributed, non-parametric tests will be used. For the analyses will be used SPSS software with critical level of 5%. The results obtained on this study aim to justify therapies for intervention with that equipment in the treatment of morbidities caused by axillary linfadenectomy.

Primary Outcome Measures

Name	Time	Method
Tactile sensitivity	2 years	Will be used Estesiômetro Semmes-Weinstein (SORRY®) to evaluate the tactile sensibility in dermatomes corresponding on the medial and superior-posterior arm.

Secondary Outcome Measures

Name	Time	Method
Blood flow velocity	2 years	The evaluation of the peripheral arterial and venous flow in the upper limbs will be accomplished through the equipment ultrasound Doppler (Nicolet Vascular Versalab SE®), and the collection site will be in the antecubital fossa, of the brachial artery and brachial vein.
