The purpose of the current study was to determine the optimal treatment duration of high voltage pulsed galvanic current (HVPC) in treating Chronic pressure ulcer. Sixty
volunteers suffering from chronic pressure ulcer were participated in this study for a treatment period of five weeks. They were divided randomly and equally into four groups
(3 treatment groups and one control group). Patients in the treatment group ( G1, G2, and G3) received HVPC for 45, 60, and 120 minutes for 7days /week respectively. While
patients in the control group received shame HVPC (45 minutes , 7days/week).wound surface area(WSA) were used to measure the outcomes before starting the study and after 3rd and 5th weeks post-treatment. It was found that, there was a significant reduction in WSA in G2 (60 minutes) and G3 (120 minutes) when compared with G1(45
minutes) and control group (shame HVPC). On the other hand , there was no significant difference between G2(60 minutes) and G3(120 minutes).It could be concluded that
the application of HVPC for 60-120 minutes, 7days/week is the optimal duration in enhancing chronic dermal ulcer healing.
