What is ultrasound?

Ultrasound, a kind of high-speed vibration, is a high-frequency sound wave produced by the current passing through the crystal. It will cause vibration and generate heat when it meets the fibrous tissue. As its therapeutic effect can reach under the skin, it is a deep thermotherapy. The ultrasound used in rehabilitation is the same as that used in obstetrics and gynecology prenatal examination or other medical examinations, but it has different functions because of different frequencies.

What disease is ultrasound targeted at?

Ultrasound can be used to relax adherent tissue, improve tissue extension, enhance tissue elasticity, promote local blood circulation, and effectively reduce inflammation, pain and so on. Clinically, it is often used in the following diseases:

• Tendinitis: tennis elbow, golfer's elbow, stenosing tenosynovitis, frozen shoulder.
• Adherent tissue: adherence after fracture or operation.
• Reduce pain: such as osteoarthritis, frozen shoulder, ankle sprains.
• Relieve swelling: ankle sprains.
• Accelerate healing of injured soft tissue: muscle injury, ligament sprains.

Precautions

Ultrasound passes through a round metal head on the machine and focuses directly on the pain area. Some gel should be applied to the skin to help the ultrasound penetrate the skin. The treatment lasts 5 minutes, and the output dose is adjusted according to the treatment site. The ultrasound probe should be kept moving to avoid a tissue cavity or scald due to heat accumulation.

Parts unfit for ultrasound therapy

• Eyes, ears, brain, spinal cord, sympathetic ganglia, genitals.
• The growing end of a bone.
• The womb of a pregnant woman.
• Areas with insufficient blood supply.
