Abstract

To determine the effect of transcutaneous electrical stimulation on the rabbit joint, we studied skin and intraarticular temperatures and pressure both before and following the stimulation in nine rabbits. An elevation in skin temperature by a mean of 0.6 degrees C (p less than 0.05) and increase in intraarticular temperature by a mean of 0.8 degrees C (p less than 0.01) was noted following the electrical stimulation. Intraarticular pressure in the stimulated joints has only a trend to increase, but not significantly. In four other rabbits, synovial tissue of the stimulated joint showed blood vessels congestion and interstitial edema. These results suggest that the analgetic effect produced by electrical stimulation on joints may partially involve intraarticular temperature and pressure alterations.
