Description
Summary:An abstract of a study by Marlowe et al determining whether low-frequency noncontact ultrasound (LFNU) can provide additional pain relief to patients with chronic wounds and whether LFNU can decrease the size of the wound is presented. Of the 6 patients, 4 showed a decreased pain average while receiving LFNU. Three showed at least a 15% decrease in average pain score over the duration of LFNU and at least a 19% decrease in pain during the day of LFNU. Two patients showed an increase in pain during LFNU. One had a history of narcotic abuse, and the other was recovering from a neurological disorder resulting in decreased sensation, possibly explaining his increased pain levels as he regained feeling. Wound surface area decreased for all subjects who received LFNU. Pretreatment average wound size was 24 cm^sup 2^, and posttreatment wound size was 17.1 cm^sup 2^. This difference was significant (P < .01).
