Shockwave Therapy

Why Shockwave Therapy?

Extracorporeal shock wave therapy (ESWT) is a type of pulsed acoustic wave resulting from excessive pressure changes. It has been used to treat musculoskeletal diseases (plantar fasciitis, lateral epicondylitis of the elbow, etc.) and wounds. Recent research has shown that ESWT is effective in stimulating biological activities that involve cellular activity. These results suggest that ESWT improves blood perfusion and can be used in tissue regeneration/ scar remodelling. Shockwave treatment is performed without anaesthesia; a treatment head and gel are applied to the area of scar treated.

Working mechanism

Shockwave works by the translation of acoustic energy into mechanical stimulation or physical energy. This encourages biological responses which promote repair of compromised tissue via complex molecular and cellular interactions and changes. The effect of shockwave therapy is dose-dependent; treatments at low intensity seem best for burn scars. Higher intensity treatments can reduce scar growth and are better for keloid/hypertrophic scars. ESWT is non-invasive and safe, it can be used within the first three months of wound healing when the scar is still fragile.

Main improvements

  • Improved elasticity of the tissue (and increased range of movement)
  • Improved pigmentation
  • Improved scar height
  • Tissue regeneration and remodelling
  • Quicker wound healing

Adverse effects

Reported adverse effects:

  • Slight pain sensation during treatment
  • Itching sensation during treatment

F.A.Q.

Is shockwave therapy painful?

Generally, shockwave therapy is not considered painful. Pain perception varies greatly between individuals. Some people find it uncomfortable but tolerable, while others may experience it as more painful. The sensitivity of the treated area also plays a role, as regions with thinner or more sensitive skin can feel more painful.

How many shockwave therapy sessions are needed to see results?

The number of treatments needed to see results can vary between 3 and 10 sessions, depending on the severity of the condition and individual responses to the therapy. Generally, multiple sessions are recommended, often spaced out over several weeks at a rate of once per week. In some cases, patients may notice improvements after just a few treatments, but full results can take several weeks to months.

For which types of scars is shockwave therapy suitable?

Shockwave therapy is suitable for various types of scars. Gentle treatments appear to be beneficial for burn scars, while stronger treatments are more suitable for large, protruding scars such as keloid or hypertrophic scars. Contractures can also benefit from shockwave therapy.
