Therapeutic ultrasound is part of electro modalities which used in rehabilitation which works by generation of sound wave. This method has been used since 1940s in diagnostic and rehabilitative medicine.
Ultrasound is applied using the head of ultrasound probe which placed direct contact with the skin with assistance on coupling gel.
Therapeutic of this ultrasound therapy includes;
- Pain Relief
- Improves Healing Process
- Promotes Relaxation
- Massage Responses
- Improves Local Circulation
- Breaks down scar tissue
How does Ultrasound Helps?
The effect of increased local blood flow circulation, which reduced swelling and inflammation, based on few studies, its proved that this therapy promotes bone healing. With the help of warm heat which passed through skin, deep tissue relaxation can be obtained which treats tissue tightness and contractile stress of the affected area.
Another way use of ultrasound therapy in through another procedure known as, Phonoporesis, which is the administration of topical medical through skin with the help of the sound wave generated by Ultrasound, commonly used are;
- Topical Pain Medication
- Selected topical skin medication
- Anti-inflammatory medication.
Ultrasound therapy can be used in treatment of various cases, includes;
- Soft Tissue Injuries
- Muscle spasm
- Micro-tear of Tissue
- Joint Inflammation
How Does Ultrasound Work?
The ultrasound waves are generated by a piezoelectric effect caused by the vibration of crystals within the probe head. The ultrasound waves that passes through the skin causes the vibration of local soft tissue, this vibration or cavitation leads a deep heating on treatment area, whereas, there will be no sensation of heat felt by patient superficially.
Dose of Ultrasound Therapy
Typically, an ultrasound therapy will take from 3-5 minutes per site of treatment. During the treatment, the probe head should remain in motion of circulating or wavy manner to avoid attenuation and wave reflection. This would lead to discomfort to the patient during the treatment.
Contraindication of Ultrasound Therapy.
Even though this therapy can be used widely, there are still some condition that need to revised in using this treatment to avoid further complication. Those are as such;
- Local Malignancy
- Metal Implantation
- Local Acute Inflammation
- Vascular Abnormalities
- Active Growth Plates
- Over Reproductive Organs
