Objective To study the therapeutic effects of proximal medial gastrocnemius release(PMGR)versus extracorporeal shock wave(ESW)for chronic plantar fasciitis(CPF).Methods This was a prospective randomized controlled study involving 100 patients with unilateral CPF admitted to Beijing Jingmei Group General Hospital from August 2021 to September 2023.They were randomly assigned in a 1∶1 radio to receive either PMGR(PMGR group)or ESW(ESW group).The aim was to compare visual analogue scale(VAS),range of motion(ROM)of ankle joint extension,the American Orthopaedic Foot and Ankle Society(AOFAS)Ankle-Hindfoot Scale,plantar fascia thickness(PFT),balance ability.Results After treatment,PMGR group had significantly lower VAS scores,significantly greater ROM of ankle joint extension,significantly higher AOFAS scores,significantly lower PFT than the ESW group(all P＜0.05).The results for star excursion balance test(SEBT)showed that the anterior side of PMGR group were comparable to those of ESW group(P＞0.05),and the other sides in PMGR group were significantly increased compared to ESW group(P＜0.05).Conclusion Compared with ESW,PMGR can effectively alleviate patient pain,expand ROM,improve ankle joint function,reduce PFT,and enhance balance ability.
