I enjoyed reading ''A Multicenter Study on the Use of Pulsed Low-Intensity Direct Current for Healing Chronic Stage II and Stage III Decubitus Ulcers,'' which appeared in the August 1993 issue of the Archives.1 This article discussed a controlled trial evaluating the effects of local electrical current on the healing of pressure ulcers. There are several other controlled trials that have also demonstrated this effect with somewhat different electrical currents.2-4 The article does, however, pose several unanswered questions.

Although the authors claim to be treating pressure ulcers, how these wounds were defined or diagnosed is never indicated. Usually, more than 60% of pressure wounds are found in the pelvic girdle and less than 25% of wounds are found on the lower extremity. In this investigation, 52% of the wounds in the control group and 42% of the wounds in the active treatment group were on the lower extremity.
