Therapeutic Ultrasound for Muscle Spasms
A muscle spasm or cramp, is a painful involuntary contraction of skeletal muscle. During a muscle spasm, the muscle becomes “stuck” and is unable to release the contraction and this results in pain. These spasms are common in athletes following physical exertion for extended periods of time such as long distance running or after playing a sport for a few hours. Most spasms occur because of dehydration or a loss of electrolytes during activity. Although spams are common in athletes, they can affect anyone due to a variety of causes such as improper posture, overuse, and vitamin deficiencies just to name a few.
Many physical therapists and chiropractors use therapeutic ultrasound to penetrate deep in the muscle tissue and alleviate muscle spasms. The sound waves from the ultrasound machine create internal heat, which increases the blood flow to the affected muscle. With an increase in blood to a spastic muscle, there is an increase of nutrients and oxygen being supplied to that muscle. The increase in circulation also helps to flush out any toxins (lactic acid) created by constant contraction of the muscle(s).
Therapeutic ultrasound also serves to reduce the pain associated with muscle cramps. If you suffer from muscle spasms, using ultrasound on a regular basis will help to relax muscles, reduce pain and inflammation, break up scar tissue adhesions, and lead you in the right path to healing naturally. It is also recommended to stretch the affected muscles and eat a nutrient dense diet to prevent spasms from occurring.
