Microcurrent Versus Transcutaneous Electrical Nerve Stimulation on Pressure Ulcer

The study uses a four-channel microcurrent therapy device to treat pressure ulcers. The treatment involves applying four electrodes to the area around the ulcer, ensuring microcurrent passage throughout the wound bed. The treatment is done three times a day, lasting 35-40 minutes. The microcurrents are delivered in a monophasic, pulsed, square-form wave pulse with a voltage of 21 mV, an intensity of 42 µA, and a current density of 4.2 µA/cm.

The study aimed to treat ulcers with TENS using a two-channel device, delivered three times a day, for 8 weeks. The device induced peripheral vasodilation and activate local blood flow, potentially promoting wound healing. The treatment was delivered using a pulse train duration of 300 ms, with an internal frequency of 100 Hz and a burst frequency of 2 Hz.

The physiotherapy program included circulatory circulatory exercises, stretching exercises, and ROM exercises.
