Ultrasound is a therapeutic modality that has been used by therapists since the 1940's. Ultrasound is applied using a wand or probe put in direct contact with the skin.
Ultrasound gel is used on the surface of the head to reduce friction and improve the transmission of the ultrasonic waves. The sound waves that pass through the skin cause a vibration of the local tissues, which can cause a local heating effect though usually no heat will be felt by the patient.
Ultrasound has been shown to cause increased tissue relaxation, local blood flow, and scar tissue breakdown. The increase in local blood flow can help reduce local swelling, chronic inflammation, and may promote bone fracture healing. The intensity of the ultrasound can be adjusted depending on the desired effect.
Ultrasound does four things extremely well:
- Increases blood flow into the treated area (accelerates healing, removes toxins).
- Produces a pain killing effect, reducing muscle spasm and promote normal function.
- Softens fibrous tissue/scar tissue, increasing flexibility and reducing chance of recurring muscle/tendon pull.
- Gently massages muscle and tendon tissue, increasing range of motion and lengthening atrophied muscle tissue.
