Therapeutic effects of a pulsed electromagnetic device in chronic cutaneous ulcers of the lower limbs

We conducted a randomized, prospective pilot study to evaluate the therapeutic effects (in particular, wound healing rate and pain relief) of one device that administers topical millimeter waves (MW) in patients with chronic skin ulcers of the lower extremities. Twenty consecutive patients with chronic skin ulcers of the lower extremities were enrolled in the study and were assigned alternatingly into two groups (experimental and control) as they randomly arrived at the clinic. For patients assigned to the experimental group, a fully-functioning device was applied; whereas, patients in the control group had a similar but nonfunctioning device applied. There was a statistically significant difference between pain values of the control and experimental groups after one month (t4) (p = 0.045), as well as between experimental group NRS values at t0 and t4 (p = 0.035).
