Abstract: Six cases of reflex sympathetic dystrophy (RSD), caused by trauma and treated with transcutaneous electrical nerve stimulation (TENS) combined with hyperthermia and exercise therapy are reported in this paper. The patients studied included 2 males and 4 females, and the age of onset of the RSD ranged from 42 to 64 years. The stimulation was given for 20 to 30 minutes daily, and the stimulation parameters were 0.1 msec. in duration; consisted of unidirectional square pulses of variable voltage not sufficient to cause muscle contraction, numbness, or pain; and delivered at 100 Hz as Meyer et al. described in their paper.
Three of the six patients began TENS therapy within three months of onset of the RSD, and showed remarkable improvement. In another patient, the symptoms decreased when the TENS treatment was started ten months after onset of the disease. The symptoms did not improve in the other two patients in which the TENS treatment was started more than twelve months after onset of the RSD.
TENS is a non-invasive procedure with no complications, and can be performed in patients of all ages. We therefore conclude that TENS is a useful method in the treatment of RSD if the patients are treated within three months after onset of symptoms.

Key words: Reflex sympathetic dystrophy (RSD), Transcutaneous electrical nerve stimulation (TENS), Trauma, conservative treatment
