ESWT, extracorporeal shock wave therapy; RMS, Rolls-Maudsley score; NRS, numeric rating scale; M, male; F, female; Gmed, gluteus medius; Gmin, gluteus minimus; P, poor; F, fair; G, good; E, excellent; INJ, Corticosteroid injection after ESWT program; NA, Data was not available

a, Symptom duration was over 24 months but patients could not remember the exact onset time.; b, Symptom duration was over 6 months but patients could not remember the exact onset time; c, Missing RMS and NRS values were replaced with the worst available assessment value and regarded as treatment failure
