Therapeutic Ultrasound

ultrasound-therapy-shoulder-injuryTherapeutic ultrasound is a very common technique that applies high-frequency sound waves to the patient’s skin using a round-headed probe with ultrasound gel to reduce friction and assist in the transmission of the waves.  It uses sound waves in the frequency of 1-3 MHz that are created by the vibration of crystals in the probe that in turn causes vibration of the local tissues and leads to a deep heating locally, even though no sensation is felt by the patient normally.
In addition to heating the tissues, therapeutic ultrasound has been shown to produce an increase in local blood flow, aid in the break down of scar tissue, reduce chronic inflammation, promote healing and cause a relaxation in soft tissues.  Also, ultrasound has been shown to produce cavitational effects, whereby the vibrations stimulate cell membranes and assist in the healing process.  Other beneficial effects you can expect include improvement of pain, swelling and increased range of motion.
