Objective—To evaluate the efficacy of extracorporeal shock wave treatment (ESWT) on pain in calcaneal spur. Methods— A single-blind randomized study was performed in which 15 patients underwent a regular treatment Pre and post-experimental design. their ages ranged from 25 to 45 years old. They were examined before and after treatment with shock waves because of pain post calcaneal spur. They were treated by shock wave therapy with 2000 strokes, 10 Hz frequency and 2.5 bar capacity. Two sessions/ week for 6 weeks. Variations in symptoms were evaluated by visual analogue scale (VAS) and Serum cortisone level. Results—A significant decrease in VAS was seen. There is a statistically significant increase in the mean cortisol level after in comparison to before Conclusion—ESWT is safe and improves the symptoms of most patients with a painful heel, and reduce pain.
