![]() ![]() "Due to the very uncomfortable sensation of these stimulators, they should not be used for muscle stimulation, only very carefully used for nerve stimulation," says Schils. Therapists use these stimulators to treat patients with debilitating pain. Interferential stimulators These units also are nerve stimulators, but each uses a pair of high-frequency waves that can penetrate deeper into the skin than TENS units. These systems are designed to stimulate only sensory nerves. ![]() In general, TENS units send electrical signals that confuse the pain pathways, blocking the sensation of pain. Transcutaneous electrical nerve stimulators (TENS) These tools can be used to decrease pain by changing how the nervous system responds to pain signals. There are two main types of electrotherapy devices: sensory nerve or motor nerve stimulator. Electrotherapy, in particular, is the application of an electric current via surface electrodes to produce controlled movement of the skin, muscle, tendon, and associated ligaments, explains Sheila Schils, PhD (biomechanics/kinesiology), a private equine rehabilitator in Wisconsin who reviewed the use of electrotherapy devices in horses at the 2009 American Association of Equine Practitioners annual convention. Inspired by the benefits of horseback riding in hippotherapy, the MiraColt is specialized, medical-grade motion simulator device designed to simulate the movements of horseback riding in a controlled and safe environment. Physical therapy refers to the use of one or more physical approaches to promote and maintain the body’s well-being, to help a horse recover from injury, and to re-educate an injured body part to move or function normally. ![]()
