Extracorporeal shockwave therapy (ESWT) is one of the most commonly recommended treatments for chronic plantar fasciosis. It has been studied extensively and, for carefully selected patients, can reduce pain and improve function. However, it is not a universal solution and understanding its role within an overall treatment plan is important.
Shockwave therapy delivers high-energy acoustic waves into the affected tissue. Although the exact biological mechanisms are still being investigated, research suggests that shockwave therapy may stimulate healing responses, improve blood flow, influence pain pathways and encourage tissue remodelling. It is not designed to 'break up' tissue or remove heel spurs, despite common misconceptions.
Clinical studies and systematic reviews generally support the use of shockwave therapy for chronic plantar fasciosis that has not improved with initial conservative treatment. Patients with symptoms lasting several months are more likely to benefit than those with very recent heel pain. Improvement is often gradual and may continue for several weeks or months after the treatment course has finished.
Like every treatment, shockwave therapy has limitations. Not every patient responds, and the degree of improvement varies considerably. Poor response may occur because the diagnosis is incomplete, the plantar fascia is not the primary pain generator, Baxter's nerve entrapment or bone marrow oedema is also present, rehabilitation has been inadequate or the underlying mechanical overload has not been addressed.
If symptoms persist despite well-conducted rehabilitation and shockwave therapy, further assessment may be appropriate. Depending on the diagnosis, carefully selected patients may benefit from ultrasound-guided regenerative injections such as prolotherapy or platelet-rich plasma (PRP). If Baxter's nerve entrapment is contributing to the symptoms, ultrasound-guided hydrodissection may be considered. Minimally invasive surgery remains a later option for patients who have exhausted appropriate non-surgical treatment.
The most important question is not simply whether shockwave therapy works, but whether it is the right treatment for your diagnosis and stage of recovery. Choosing the correct treatment begins with understanding the cause of the pain rather than applying the same intervention to every patient.
