Twenty patients with chronic wounds will be managed by the high-voltage pulsed current for 45 as the total treatment duration and the polarity will be reversed after 22 minutes, three sessions per week for six weeks.

Twenty patients with chronic wounds will be managed by microcurrent therapy for 40 minutes, three sessions per week for six weeks.

The treatment session duration is 45 minutes (Reverse the polarity after the first 22 minutes)

A sterilized transparency film will be placed over the ulcer. The ulcer perimeter was traced by using the film tipped transparency marker. Each ulcer was traced three times to establish measurement reliability. After tracing, the side of the transparency film facing the ulcer will be cleaned with a piece of cotton and alcohol. Carbon paper was placed over the 1-mm-squared metric graph paper. The traced transparency film was placed over the carbon paper with white paper in between and the tracing will be transcribed onto the metric graph paper. WSA was calculated by counting the number of square millimeters on the metric graph within the wound tracing. The mean value of the three trials was calculated and taken to be the wound surface area.

Assessment of wound volume was done by saline injection tool. A syringe of twenty cubic centimeters filled with normal sterilized saline was used. The patient was positioned in a comfortable position that allows the wound to be filled with the saline solution maximally. The saline was injected into each wound until its filling. The amount of saline injected was detected in cubic centimeters. These measurements were conducted for each patient before and after of treatment.
