Effects of adjuvant low-dye Kinesio taping, adjuvant sham taping, or extracorporeal shockwave therapy alone in plantar fasciitis: A randomised double-blind controlled trial.

Abstract

Extracorporeal shockwave therapy (ESWT) is known as one of the most effective treatment methods in plantar fasciitis (PF). Low-dye taping, which is the most preferred method of banding treatments, provides an analgesic effect by correcting biomechanics. It was aimed to compare the efficacy of adjuvant low-dye kinesio-taping (KT), sham-taping, or ESWT alone in PF. In this double-blind, sham-controlled study, 45 patients with PF were randomised into Group 3 (Group 1: ESWT plus low-dye KT, n=15; Group 2: ESWT plus Sham-taping, n=15; and Group 3: ESWT only, n=15) five-session ESWT were administrated. KT was performed and changed every 1-week for the ESWT sessions in Groups 1 and 2. The main outcome measures were the visual analogue scale (VAS) change, the heel tenderness index (HTI), foot function index (FFI). The patients were evaluated at the beginning and end of the treatment and at the 4-week follow-up. The demographic characteristics and baseline outcomes between groups were similar (P>.05). No significant difference was found between Groups 1 and 2, Groups 1 and 3 and Groups 2 and 3 with respect to VAS, HTI changes during the 4-week follow-up. VAS and HTI changes were observed in all three groups, there were no differences between groups. Repeated-measures ANOVA showed a significant interaction between the time and the groups in FFI-total (F3.919 =2.607; P=.043). For the FFI total, there was only a significant difference in favour of Group 1 when compared with Group 2 (P=.027). Although low-dye KT in addition to ESWT was more effective on foot function improvement than additive sham-taping and ESWT alone, it did not provide a significant benefit on pain and heel tenderness because of PF. The study was registered at the U.S. National Institutes of Health (ClinicalTrials.gov) (NCT03904966).
