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 <.001). Vitamin D level had a significant negative effect on plantar fascia stiffness (β=-1.91, R2 =.117, p=.03). Conclusion: The results of the research showed that plantar fascia stiffness was higher in individuals over 65 years of age. The stiffness of PF is decreased as the vitamin D level improved.}, number={2}, publisher={Dokuz Eylul University}, organization={Scientific Research Projects Unit of Bitlis Eren University}
