Radial Shock Wave Therapy: What Is It And How It Works

Tendinopathy is the deterioration of the collagen protein that forms a person’s tendon. It is usually the broad term used to pertain to any tendon condition that causes swelling and pain. Tendinopathy is a fairly common health concern experienced by about 2% to 5% of the general population. The most common body parts affected by tendinopathy are the wrists, shoulders, shins, knees, heels, and ankles.

Because it can be excruciating, people who suffer from tendinopathy often seek the help of a pain management specialist in Singapore for the appropriate treatment. Among the standard options for treating patients with tendinopathy these days is Radial Shock Wave Therapy (RSWT). Read on to learn more about RSWT and how it can help you manage or treat the inflammation or pain in your tendon.

What is Radial Shock Wave Therapy (RSWT)?

Radial Shock Wave Therapy (RSWT) is a procedure for treating tendon conditions by passing shock waves through a patient’s skin. It utilises a specialised machine that creates mechanical shockwaves proven to boost blood flow into the injured site and increase the healing rate for soft-tissue tendinopathy.

In other words, RSWT is an advanced, non-invasive treatment mechanism that improves blood circulation and accelerates the healing process of injured tendons. Here are some of the most common conditions that are treatable by RSWT:

  • Plantar Fasciitis
  • Patellar tendonitis
  • Achilles Tendinitis
  • Quadriceps Tendinitis
  • Biceps/Triceps Tendinitis
  • Medial Epicondylitis
  • Lateral Epicondylitis
  • Trochanteric Tendonitis
  • Shin Splints

How does RSWT work?

Usually, when you experience persistent pain, your body tends to recognise no longer that there exists an injury in that area. As a result, your healing process is being shut down, and you do not feel any relief. Through RSWT, ballistic sound waves are sent to penetrate extensively through your soft tissue and create a new inflammatory condition in the treated area. Once this happens, your body’s natural healing response is triggered again.

Additionally, the energy released during the RSWT procedure can also cause the cells in your soft tissue to discharge certain biochemicals that can strengthen your natural healing process. These chemicals enable a variety of new microscopic blood vessels to be built in your soft tissue. However, to fully achieve these benefits, RSWT should be performed once a week for a set of 4 to 5 treatments.

Depending on the number and size of the areas to be treated, an RSWT session usually takes about 5 minutes. During the treatment, you may experience some minor discomfort, but this is typically not a cause of concern. Painful areas can help isolate those areas truly injured. According to the extensive studies on the treatment, the success rate of RSWT procedures is between 72% to 80%.


Overall, RSWT is an excellent option for treating various kinds of tendon injury because it is a non-invasive procedure that effectively reduces pain and improves tendon functions. By knowing what RSWT is and how it works, you can better understand its benefits and determine more precisely whether or not it is the best ankle pain solution in Singapore.
