Abstract

|
The purpose of this study was to determine whether vasodilation occurs when interferential current is applied to the cervical sympathetic chain and peripheral sympathetic nerves. A digital thermometer was used to record skin temperature change. The protocols used for interferential stimulation were 90-100 Hz, applied for 20 minutes via two pairs of electrodes 1) to the throat and 2) to the forearm. Forty subjects were stimulated at each of the two sites. There was no significant correlation between inital skin temperature, sex or age and temperature change. Even though there was a statistically significant temperature increase with cervical sympathetic chain stimulation, this had no clinical vasodilatory effect. More research on interferential current stimulation is needed so that the potential benefits to normal subjects and patients is better understood.
