Effects of Ageing and Vitamin D Level on Plantar Fascia Stiffness

Abstract

Purpose: The study aimed to examine plantar fascia stiffness in individuals over and under 65 years of age, and to question the predicted effect of age and vitamin D level on plantar fascia stiffness. Material and Methods: Forty adults were included to the study. The participants were divided into two groups as equal or above 65 years and below 65 years. Plantar fascia stiffness was evaluated using a digital hand-held myotonometer. Vitamin D levels of all participants were recorded. Results: Plantar fascia stiffness was higher in the right (∆= 141.80±39.86 N/m, p=.001) and left foot (∆=116.85±38.45 N/m, p=.004), in participants over 65 years of age. Age had a significant positive predicted effect on plantar fascia stiffness (β= 6.7, R2= 0.31, p
