Title:
INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING SYSTEM, AND INFORMATION PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/008688
Kind Code:
A1
Abstract:
An information processing device (100) that obtains measurement information relating to the movement of each leg of a patient. On the basis of the obtained measurement information, the information processing device (100) specifies at least one candidate for the time at which the foot of the free leg of the patient touches the ground for each step during a patient walking period. The information processing device (100) specifies a plurality of candidate groups having selected and combined therein at least one candidate specified for each step during the walking period. On the basis of cumulative travel distance calculated for each step during the walking period, the information processing device (100) evaluates, for each candidate group, the degree at which a prescribed relationship appears between the ground contact positions for each leg of the patient during the walking period. On the basis of the evaluation results, the information processing device (100) selects one of the candidate groups from among the plurality of candidate groups and outputs the selected candidate group.
