Aim of this study was to examine the influence of different energy flux densities of extracorporal shock waves on clinical outcome. 60 patients with chronic plantar fasciitis were included in this study and randomised either to receive 2000 impulses of extracorporal shock wave therapy with a positive energy flux density of 0.22mJ/mm², with an ED+ of 0.33mJ/mm² or placebo (received the same regimen of placebo therapy) once a week for three weeks. For blinding, all patients received local

Primary end point was the success rate 12 monthss after intervention based on the AOFAS score (first primary end point) and on the Roles and Maudsley score (second primary end point). Secondary end point was the success rate 3 months after intervention based on the AOFAS score and the Roles and Maudsley score and, in addition, subjective pain ratings as well as walking ability 3 and 12 months after intervention. The primary end point could be assessed in 85% (both intervention groups) versus 80% (placebo group). In the secondary end point we noticed a better outcome of the intervention groups regarding subjective pain raitings 12 months after intervention, but overall no significant differences were found. No relevant side effects were observed. The result of a post-hoc power analysis was that a sample size of 713 patients is needed in a follow-up study to verify differences between the groups.
