Abstract

Background Plantar fasciitis (PF) is an inflammation of the plantar fascia on the bottom of the foot, characterized by stiffness of medial arch and pain especially during the first steps. It can effect on daily living activities such as walking and a difference in the plantar pressures during walking can be expected (1). But, no studies were found in the literature related to this situation.

Objectives The aim of this study was to investigate the dynamic plantar pressure during walking and compare the pedography measurements of the affected and unaffected feet of patients with plantar fasciitis during walking.

Methods Forty patients (28 female, 12 male) with unilateral plantar fasciitis were included in the study. Pain status and functionality was assessed with a visual analog scale (VAS) and Foot Function Index (FFI), respectively. EMED-m pedography platform (Novel GmbH, Germany) was used for dynamic foot plantar pressure measurements. Maximum force, contact area and contact time were measured for total object and hind foot in both affected and unaffected feet. These measures were recorded three times and average values were used in the analysis.The data were not distributed normally and as a result, non-parametric tests were used for interpreting the data.

Results Average age, height and weight were 51.1 (min-max: 74–33), 165.7 (min-max: 150–190), 82.4 (min-max: 60–110), respectively. VAS was 7.5 (min-max: 6–8) FFI was 55.9 (min-max: 40–63). The results related to pedography measurements were given in Table 1. While, it was observed that hind foot maximum force and contact area were diminished in the affected foot, no differences were found in measures related to total object nor contact time of hind foot. Although a moderate relationship was found between pain status and functionality (rho: 0.57, p<0.001), none of these variables were correlated with pedoghraphy measures (p>0.05).

Conclusions According to the results of this study, there was a difference in plantar pressures between affected and unaffected feet in plantar fasciitis patients. It seems that the difference is not related to pain status nor functionality. Treatment strategies aiming to resolve this difference might be beneficial to improve outcomes of the treatment. More studies are needed to understand the importance of the dynamic foot pressures during walking in this patient population.
