One hundred and three patients with unilateral chronic greater trochanteric pain syndrome (GTPS) were randomized to receive electromagnetic focused extracorporeal shockwave treatment (F-ESWT) with a specific exercise protocol or sham F-ESWT with the same exercise protocol. The primary outcome of interest included pain measured using the visual analogue scale (VAS) at 2-months follow-up. Secondary outcomes included the Harris Hip Score (HHS), the Lower Extremity Functional Scale (LEFS), EuroQoL-5 Dimensions Questionnaire (EQ-5D), and the Roles and Maudsley score. As well, incidence of complications were also measured. All secondary outcomes were measured at 1, 2, 3, and 6 months post-intervention. Results revealed that mean VAS was statistically significantly lower in the F-ESWT group compared to the sham (p<0.001) at 2-months follow-up. Furthermore, HHS, RM, and EQ-5D scores were statistically significantly improved in the F-ESWT group at all timepoints (p<0.05 for all). LEFS scores were statistically significantly improved at all timepoints in the F-ESWT group except for at 1-month follow-up (p=0.25). Finally, no complications were observed in either group.
