Therapeutic ultrasound can treat damaged tendons. Sound waves vibrate and provide a massaging effect. In simple treatments like cold therapy, therapists apply ice to reduce swelling and prevent hematomas. In iontophoresis treatment, therapists use electrical currents to drive veterinary-prescribed drugs into trouble spots. It is non-invasive and sterile and the medication is concentrated locally.
Therapists use electrical stimulation to assess and treat nerve and muscle tissues.
The treatment can increase circulation by causing blood vessels to dilate. Therapists apply electrodes to the skin to deliver low-voltage, intermittent stimulation to surface nerves. The technique blocks the transmission of pain signals and releases endorphins, the body's natural painkillers. Turning off the pain signal allows the body to heal. Exercise programs are also developed for injured horses.
