The purpose of this study was to evaluate the effect of pulsed high-frequency, high peak power electromagnetic energy (Diapulse) in the healing of pressure ulcers. Patients with Stage II ulcers unhealed within three to 12 weeks and those with Stage III ulcers unhealed within eight to 168 weeks by conventional methods were ere included in the study. When Diapulse was added to conventional therapy during the nine-mouth study, all 22 patients healed as evidenced by photographs and measurements of the ulcers. Stage II ulcers healed in one to six weeks (mean 2.33) and all Stage III ulcers healed in one to 22 weeks (mean 8.85). The increased healing time can provide significant cost savings and improved patient care.
