Extracorporeal shockwave therapy (ESWT) is not useful for patients with plantar fasciitis, according to the results of a randomized controlled trial reported in the Sept. 18 issue of the Journal of the American Medical Association.
However, this finding differs from that of a prior study showing that half of patients who received ESWT could walk without pain in six months. “While all five placebo-controlled trials of ESWT in chronic plantar fasciitis have reported benefit of variable magnitude, methodological limitations may have influenced their outcome,” write Rachelle Buchbinder, MBBS, MSc, from the Cabrini Medical Centre in Malvern, Victoria, Australia, and colleagues.
In this double-blind trial conducted between April 1999 and June 2001, 160 patients completed the 15-week protocol and were randomized to treatment with ultrasound-guided ESWT given weekly for three weeks to a total dose of at least 1000 ml/mm2, or with identical placebo to a total dose of 6.0 ml/mm2.
