Effect of aging on plantar sense: Quantitative evaluation using a SWM

Abstract

[Purpose] Plantar sense was measured quantitatively using a Semmes-Weinstein monofilament (SWM), and its changes with age were investigated. [Subjects] The subjects were 62 men and 174 women, a total of 236 persons, in three age groups: 20-29 years of age, 55-74 years of age, and 75-94 years of age. [Methods] A SWM was used to assess plantar sense at a total of eight locations, and the effect of aging was investigated at each site. [Results] Plantar sense after the age of 55 declined, and the decline at the heel was significant compared to the other sites. [Conclusion] The results suggest that plantar sense declines with age, and that the decline at the heel is greater than in the other regions.
