Summary
Changes were revealed in the peripheral nerve fibers in the form of reversible irritation phenomena following irradiation of guinea pigs extremities with therapeutic doses of pulsed ultrasound, the intensity being 0.5W/cm2 and the frequency 1625 kc for 5 to 10 min. In irradiating for 3 minutes with constant ultrasound, the intensity being 1 W/cm2 and the frequency −1625 kc, the changes seen in the nerve, skin and muscles were not only reversible but also degenerative.
