Diagnostic ultrasound is a specialized method of physical therapy that uses sound waves to create vibrations in tissues affecting the muscles, ligaments, and bones. Those vibrations generate heat deep in the tissues—an area heating packs cannot reach in the same way. Treatment may help relieve pain, increase blood flow, reduce swelling and inflammation, and promote tissue healing.
Ultrasound may be used to help relieve painful symptoms and support movement when arthritis or general joint discomfort is limiting daily activity.
Common uses include bursitis, tendinitis, frozen shoulder, muscle spasms, and sprains, strains, or tears involving soft tissue.
By supporting circulation and tissue healing, ultrasound may be part of an individualized plan for fractures and other recent injuries.
During an ultrasound treatment, your physical therapist applies gel to the ultrasound applicator to minimize friction and promote transmission of sound waves. The waves are absorbed by tendons, ligaments, and connective tissues. Thermal energy may help reduce pain, increase circulation, and make muscles easier to stretch, while non-thermal effects may support repair of damaged tissue and help loosen muscles. At your initial appointment, your therapist will consider your physical exam, medical history, condition, and health restrictions to determine whether ultrasound belongs in your personalized treatment plan.
