Extracorporeal Shock Wave Therapy utilises devices that generate pulses of high-pressure sound that travel through the skin. For reasons that are not fully understood yet, soft tissue and bone that are subjected to these pulses of high-pressure energy heal back stronger.
It is a safe and effective, non-invasive (no incisions) alternative that eliminates many of the risks associated with conventional surgery.
ESWT is indicated for patients with heel pain or tennis elbows who have not responded to conservative treatment such as local injections and physiotherapy.
ESWT delivers high-energy sound waves, or acoustical energy, to the affected area to create a micro trauma that promotes revascularization and triggers the body’s natural repair mechanisms.
Benefits of ESWT include:
- Non-invasive treatment
- High success rate
- Single to dual treatment protocol
- Fast recovery with quick return to work and normal activities
- Studies have shown very high success rates in eliminating or significantly reducing pain
- On the day of the procedure, the patient will arrive at the treatment location approximately one half hour before the scheduled appointment
- Meet physician and the ESWT technician
- Recline in a comfortable chair or bed with injured foot resting on a large, fluid-filled cushion
- Typically, the treatment area is numbed with local anaesthesia
- After localizing the inflamed fascia, the injured heel receives several thousand shockwaves during this 20 minute outpatient procedure
- Patients are discharged directly home from the treatment centers
It may take as long as 12 weeks to see the full benefit of an ESWT treatment.
The beneficial effect of the high-pressure waves may be from the growth of new blood vessels (“neovascularization”) in small cavities that are created by the pulses. New blood vessels to an area of tissue would promote healing.
