Evaluating the Effects of an Instrument-Assisted Stretching Technique on Plantar Fascia Mechanics: A Randomized Controlled Pilot Study

Abstract

Aim: Stretching exercises are a widely employed method in the rehabilitation of foot-ankle pathologies. The purpose of this study was to examine the effectiveness of various stretching exercises, implemented with the aid of a newly designed device, on plantar fascia stiffness in healthy individuals. Method: A double-blind randomized controlled pilot trial was conducted with nineteen healthy participants. Participants were divided into two groups: plantar fascia-specific stretching (PFSS) and Achilles tendon stretching (ATS). All participants performed the stretching exercises (PFSS or ATS) on their dominant leg using a specially designed instrument, while the non-dominant leg was stretched without it. Plantar fascia stiffness was measured with a myotonometer before and after the intervention. Each stretching session included 10 repetitions, held for 10 seconds. The Mann–Whitney U test was used for between-group comparisons, while the Wilcoxon signed-rank test was used to analyze within-group pre- and post-stretch differences. Results: Instrument-assisted stretching resulted in a significant increase in plantar fascia stiffness compared to traditional (non-instrument) stretching techniques in both PFSS (p=0.008) and ATS groups (p=0.005). No statistically significant differences were observed between PFSS and ATS with or without the instrument (p>0.05). Conclusion: This pilot study suggests that the novel instrument has the potential to enhance the effectiveness of stretching interventions for the plantar fascia. Incorporating instrument-assisted stretching techniques into rehabilitation plans may support future clinical applications.
