Differences in the Impact of Plantar Fasciopathy on the Spatio-Temporal Gait Parameters between Participants with Bilateral Plantar Fasciopathy and Healthy Subjects: A Cross-Sectional Study.

Abstract

The aim of the present study was to determine the level of association of the spatio-temporal gait parameters in subjects with and without plantar fasciopathy. The second objective was to analyze whether differences in spatio-temporal parameters between both groups exist. Seventy-four subjects divided in two groups participated in the study, one presenting subjects with plantar fasciopathy for more than three months (n = 31), and the other group comprising subjects without plantar fasciopathy (n = 43). The spatio-temporal parameters were measured using Optogait. Decreased step length (p < 0.001), increased contact phase (p < 0.001), increased double support (p < 0.001), increased load response (p < 0.001), increased pre-swing (p < 0.001), increased gait cycle (p = 0.002), decreased stride (p < 0.001), decreased speed (p < 0.001), decreased cadence (p < 0.001), decreased phase flatfoot (p = 0.001), and increased propulsion (p < 0.001) in subjects with PF showed statistically significant differences when compared with the control group.. Furthermore, the level of association between the spatio-temporal parameters was different when comparing the groups. These findings may help when assessing potential plantar fascia injuries, and they may serve as a tool that helps with clinical decision-making, or as a clinical measurement in a treatment and follow-up program.
