PROBLEM TO BE SOLVED: To provide an overturning risk determination device capable of determining overturning risk easily with high accuracy.SOLUTION: An overturning risk determination device 100 comprises: a walking information acquisition part 140 for acquiring walking information of a user; a myoelectricity sensor 111 for measuring a first myoelectricity on a front surface of a thigh part of the user, and measuring a second myoelectricity on a rear surface of the thigh part; a control circuit 120 for identifying a section of a leg erection period using the above-mentioned walking information, then calculating a degree of co-shrinkage of legs of the user based on the first myoelectricity and second myoelectricity in the leg erection period, then determining whether or not the degree of co-shrinkage is equal to or higher than a first threshold; and an output part 112 for outputting a signal for indicating the fact that, overturning risk of the user is high, when the degree of co-shrinkage is equal to or higher than the first threshold.SELECTED DRAWING: Figure 12 【課題】簡単に高い精度で転倒リスクを判定することができる転倒リスク判定装置を提供する。【解決手段】転倒リスク判定装置１００は、ユーザの歩行情報を取得する歩行情報取得部１４０と、ユーザの大腿部の前面の第１の筋電を計測し、かつその大腿部の後面の第２の筋電を計測する筋電センサ１１１と、上述の歩行情報を用いて立脚期の区間を特定し、立脚期の第１の筋電と第２の筋電とに基づいて、ユーザの脚の共収縮の度合いを算出し、その共収縮の度合いが第１の閾値以上であるか否かを判定する制御回路１２０と、その共収縮の度合いが第１の閾値以上の場合には、ユーザの転倒リスクが高いことを示す信号を出力する出力部１１２とを備える。【選択図】図１２
