PROBLEM TO BE SOLVED: To provide a method for exactly evaluating a walking age on the basis of the measurement of walking behavior.SOLUTION: A walking age evaluation method for evaluating a walking age on the basis of walking parameters measured during walking behavior includes: measuring walking behavior using a sheet type pressure sensor; measuring walking speed using an acceleration sensor; using at least a right walking angle, a left walking angle, a walking cycle, the length of a both-legs supporting period, and the length of a step as walking parameters; and displaying a walking age calculated by a multiple regression equation using explanatory variables including these walking parameters.
