Abstract
To explore the therapeutic efficacy of extracorporeal shock wave (ESW) for persistent heel pain. A total of 98 patients of persistent heel pain were randomly divided into ESW treatment and control groups (n=49 each). Treatment group had ESW while control group received infrared physical therapy. And their visual analogue scale (VAS) scores were assessed. After one course of treatment, VAS heel pain and function scores were (39.6±6.2) and (25.1±4.6) in ESW group versus (32.3±6.5) and (17.4±7.2) in control group. And before treatment, (16.5±4.6) and (14.4±8.6), (16.1±4.7) and (14.6±8.4) respectively. Heel pain significantly decreased with functional improvement (all P<0.05). After one course, the effective rate was 65% (32/49) in treatment group. And the improvement rate of 31% (15/49) was better than control group [27% (13/49) and 63% (31/49)] (all P<0.05). ESW treatment of persistent heel pain was more efficacious than physical therapy and it could be applied clinically. Key words: Shock waves; Heel spur
