Ultrasound Therapy: Ultrasound devices pass vibrations through the soft tissue in order to increase the heat within the tissue, which in turn increases blood flow and reduces pain. The heat produced also relaxes muscles and improves the ability of soft tissues to stretch. In a study published in the Journal of Zhejiang University Science found encouraging evidence that ultrasound can be used to stimulate tendon-bone healing.
Pulsed Shortwave Therapy / Pulsed Shortwave Diathermy (PSWD): Special devices use a high-frequency electromagnetic current to promote tissue healing and ease pain. This type of therapy has thermal (mild heating) and non-thermal effects and is effective at treating muscles, nerves, and areas of swelling.
Transcutaneous Electrical Nerve Stimulation (TENS): A TENS machine is a small, battery-operated device that has leads connected to sticky pads called electrodes. Pads are attached directly to skin and small electrical impulses are delivered to the affected area of your body, which is felt as as a tingling sensation.
Electrical impulses can reduce the pain signals going to the spinal cord and brain, which may help relieve pain and relax muscles. They may also stimulate the production of endorphins, which are the body’s natural painkillers.
