How Does ESWT Work?

ESWT uses special sound waves called shock waves. These shock waves are short, powerful pulses that can travel through water and soft tissues in the body. During the treatment, a device creates these shock waves and directs them to the painful area through the skin using a gel. The shock waves then help reduce pain and promote healing in the affected tissues.

Conditions Treated with ESWT

ESWT is used to treat various conditions that cause pain, including:

• Frozen Shoulder: Stiffness and pain in the shoulder joint.

• Tennis Elbow: Pain around the elbow caused by overuse.

• Plantar Fasciitis: Heel pain due to inflammation of the tissue on the bottom of the foot.

How ESWT Helps with Pain

The exact way ESWT works to reduce pain is not fully understood, but it is believed to help in several ways:

• Reducing Inflammation: The shock waves can reduce swelling and irritation in the tissues.

• Promoting Healing: The treatment can stimulate the growth of new blood vessels and tissue, helping the body repair itself.

• Reducing Pain Signals: The shock waves can reduce the pain signals sent to the brain, making the pain feel less intense.

The Procedure

• Preparation: Before the procedure, the skin over the painful area is cleaned and a gel is applied to help transmit the shock waves.

• Shock Wave Application: The device is placed against the skin, and the shock waves are directed to the painful area. The treatment usually lasts a few minutes.

• Aftercare: After the treatment, there may be some temporary discomfort, but most people can return to their normal activities quickly.

Benefits of ESWT

• Non-Invasive: ESWT does not require surgery or injections.

• Quick Recovery: Most people can go back to their daily activities shortly after the treatment.

• Effective: Many people experience significant pain relief after a few sessions.

Possible Side Effects

ESWT is generally safe, but some people might experience:

• Temporary pain or discomfort at the treatment site

• Minor bruising or swelling

• Skin redness

Who Should Avoid ESWT?

ESWT is not suitable for everyone. It should be avoided by:

• Pregnant women

• People with certain blood clotting disorders

• Individuals with pacemakers or other implanted devices

• People with open wounds or infections in the treatment area

Comparing ESWT and Ultrasound Therapy

• Frequency of Sound Waves: ESWT uses lower frequency sound waves compared to therapeutic ultrasound.

• Effect on Tissues: ESWT does not cause heating of the tissues, while ultrasound can produce both thermal (heat) and non-thermal effects.

• Similarities: Both treatments use sound waves and a coupling gel to treat pain and are non-invasive.

Conclusion

Extracorporeal Shock Wave Therapy (ESWT) is an innovative and effective treatment for various types of pain, particularly in the muscles and tendons. It offers a non-invasive option for those seeking relief from chronic pain without the need for surgery or long recovery times. If you have persistent pain, ESWT might be a helpful treatment to discuss with your healthcare provider.
