Polarity Action in Electrical Stimulation Transcutaneous Donors for Treatment Areas Burned Patients

Study Overview
=================
Brief Summary
-----------------
To evaluate the effect of the polarity of the electric current in healing.

Detailed Description
-----------------
The objective of this study is to evaluate the effect of the polarity of the current in healing. Both will be compared to the effects of electrical stimulation of high voltage (HVES) and neuromuscular transcutaneous electrical stimulation (TENS) in the treatment of donor sites (DA) of burn patients. It is a prospective, controlled clinical, randomized, blinded. Will be assessed 60 subjects aged 18-59 years, of both sexes, underwent the surgical procedure of grafting (PCE) were randomly divided into small blocks 5:5:5 three groups: undergoing therapeutic procedure with HVES undergoing therapeutic procedure with TENS and control. Therapeutic procedures will be applied around the DA, thigh or scalp, after 24 hours of PCE until complete healing. The variables will be the healing time estimated by the removal of the dressing rayon, clinical evaluation, scar quality, the Vancouver scale; pain, the pain numerical scale evaluation (PNS); blood perfusion by thermography; quality of healing by digital imaging, quantification of areas of crusts by the software Image J; skin biomechanical aspects as firmness, the durometer being performed reassessment at the end of treatment. Data will be submitted to analysis of normality by the Shapiro-Wilk test and the effect of behavior among groups and pre- and post-intervention will be evaluated by ANOVA-two way followed by post-hoc (Bonferroni) or Friedman, with p <0.05. Comparing groups, before a normal distribution is applied ANOVA followed by Tukey, and otherwise will be applied the Kruskal-Wallis test and post-hoc Dunn, p<0.05.

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: High voltage<br>The applied parameters of high voltage electrical stimulation are medium voltage of 100 volts, an increase in the course of the session, frequency of 10 Hz, with application in the donor areas of thigh or scalp for 40 minutes, 25% above of level engine daily until complete epithelialization, and removal of the dressing type rayon. | Device: High voltage<br>* Electrical stimulation treatments will be made in donor areas (scalp and thigh) in patients burns<br>|
| Experimental: Neuromuscular transcutaneous electrical stimulation (TENS)<br>10 Hz, 40 min, 200 μs and 25% above of motor level | Device: Neuromuscular transcutaneous electrical stimulation (TENS)<br>* Electrical stimulation treatments will be made in donor areas (scalp and thigh) in patients burns.<br>|
| Experimental: Control Group<br>There will be no intervention | Other: Control Group<br>* The control group will not have electrical stimulation however, will be evaluated with digital digital imaging, thermography imaging, skin hardness and subjective pain and healing scales<br>|
