Ultrasounds and X-rays can be used for more than just the standard, common usage; they can be used for therapeutic reasons, as well. Ultrasound machines omit a high frequency, which can help speed up the healing process of a joint, muscle or tendon. It helps because it induces hyperemia (increased blood flow) in the areas.
The thermal effects of an ultrasound or X-ray produced by sound waves heal and reduce inflammation. The vibration also stimulates cell membranes, encouraging the repair of cells in inflamed areas. It can aid in reducing swelling, increase blood flow, decrease pain, stiffness, spasms and so much more!
