In a prospective clinical study, the effectiveness of shock waves on painful heel syndrome in 80 patients (20 men and 60 women) with an average age of 48 years was investigated. Six patients had bilateral treatments. Each treatment consisted of 1000 impulses of shock waves at 14 kV. A 100-point scoring system (70 points for pain and 30 points for function) was used for evaluation. The intensity of pain was measured with a visual analog scale from 0 to 10. The overall results were no complaints in 20.6%, significantly better in 52.9%, slightly better in 17.6%, and unchanged in 8.8% of 64 patients (68 heels) with 12 weeks followup; no complaints in 59.3%, significantly better in 27.7%, slightly better in 13% of 52 patients (54 heels) with 6 months followup. None of patients’ symptoms became worse. Seventeen patients (18 heels) who did not respond favorably to the first treatment had significantly better results after a second treatment. There were no device-related problems, and no systemic or local complications. Shock wave treatment is a new modality of therapy that is safe and effective in the treatment of patients with painful heel syndrome.
