The Ultrasound therapy is the application of ultrasound waves to the treatment of diseases and injuries. The Ultrasound therapy either pulsed or continuous applies in inflammatory lesions of muscle and tendon. It is important to note the sonic origin of this therapy, especially in patients with bone weakness ( fracuras or osteoporosis ). The treatment is performed with an ultrasonic therapy equipment that emits ultrasonic waves through a quartz crystal in the emitter head.
