Abstract: The present invention facilitates adjustment of the strength of an elastic orthotic that assists the movement of an orthotics user by whom the elastic orthotic is worn. This calculation device for calculating the optimum elastic strength of an elastic orthotic comprises a storage unit in which elastic strength and kinematic properties established through experiments in which a plurality of people wear elastic orthotics are stored in advance, and a mathematical optimization processing unit that calculates the optimal elastic strength on the basis of a prescribed evaluation index on the basis of the kinematic constraint condition of an orthotics user and the elastic strength and kinematic properties.

Abstract: A risk estimation apparatus includes a data acquisition unit that acquires measured data of foot pressures of the left foot and the right foot obtained by sensors that are provided in shoes and measure the foot pressures, a stance phase identification unit that identifies a starting timing and an ending timing of a stance phase of each of the left foot and the right foot from the measured data of the foot pressures, and a risk estimation unit that estimates a risk of abnormality of a lower limb on the basis of asymmetry between the foot pressures of the left foot and the right foot during the stance phase.
