Ultrasound therapy is used to minimize muscle pain and movement dysfunction. Therapeutic ultrasound uses sound waves to deliver deep heat to the treated tissues. The treatments may help reduce stiffness, swelling, and pain, increase circulation, and promote pain-free movement. Ultrasound therapy may be used alone or in conjunction with stretching, therapeutic massage, heat, or gentle chiropractic manipulation. Ultrasound therapy is a painless procedure, and many people find it relaxing. Your chiropractor will only expose the area of skin that is to be treated. A conduction gel will be put on your skin. The ultrasound conduction device, a small unit about the size of a computer mouse, will be gently placed on your skin to deliver the ultrasound treatment. When your treatment is completed, the conduction gel is wiped off. Following ultrasound, your chiropractor may help you stretch your joints. Passive range of motion exercise may be followed by active range of motion exercise. It may be more effective to receive a massage or gentle chiropractic manipulation following ultrasound.
