PROBLEM TO BE SOLVED: To provide a stabilometer and a centroid oscillation evaluation method that realize shortening of measuring time and reduction in a burden on a subject.SOLUTION: A stabilometer comprises: a platform on which a subject gets a load detection part that detects load on the platform a time measuring part that measures time an operation part that calculates centroid locus data on the basis of the load detected by the load detection part and the time data measured by the time measuring part and a biological evaluation part that evaluates centroid oscillation of the subject. The calculation part includes: a determination part for determining a time point (Tb) when the subject finished placing one foot on the platform and a determination part for determining a time point (Tc) when the subject in the state of placing one foot on the platform takes the other foot off a ground. The biological evaluation part evaluates the centroid oscillation of the subject in a period from the time point (Tb) to the time point (Tc) on the basis of at least one of the centroid locus data, load fluctuation data per unit time and the time data.COPYRIGHT: (C)2014,JPO&INPIT【課題】測定時間の短縮及び被験者への負担を軽減することができる重心動揺計及び重心動揺評価方法を提供する。【解決手段】被験者が乗る載台、載台上にかかる荷重を検出する荷重検出部、時間を計測する時間計測部、荷重検出部が検出した荷重及び時間計測部が計測した時間データに基づき重心軌跡データを算出する演算部、被験者の重心動揺を評価する生体評価部、を備え、演算部は、被験者が載台上に一方の足を乗せることを完了した時点(Tb)を判定する判定部、載台上に一方の足を乗せた状態の被験者が他方の足を地面から離した時点(Tc)を判定する判定部、を有し、生体評価部は、重心軌跡データ、単位時間あたりの荷重の変動データ、時間データの少なくとも1つに基づき、時点(Tb)から時点(Tc)までの間の被験者の前記重心動揺を評価する。【選択図】図2
