PROBLEM TO BE SOLVED: To provide a massage machine that can improve estimation accuracy of a body condition of a person to be treated.SOLUTION: A massage machine includes a therapeutic element 26 to apply a stimulus to a living body, a living body physiological information acquisition part 32 for measuring a biological reaction at the time when the stimulus is applied to the living body, a therapeutic element control part 41 for changing force, a position, and a locus in applying the stimulus to the living body, and an evaluation part 42 for applying stimuli of different stimulation force adjusted by the therapeutic element control part 41, and, based on a plurality of biological reaction results at that time, determining a biological state. The evaluation part 42 detects a body condition by combining the living body physiological information on a person to be treated with physical quantity information.COPYRIGHT: (C)2016,JPO&INPIT【課題】被施療者の身体状態の推定精度を向上させることができるマッサージ機を提供する。【解決手段】マッサージ機は、生体に刺激を与える施療子26と、生体に刺激を与えたときの、生体反応を計測する生体生理情報取得部32と、生体に刺激を与える際の力や位置や軌跡を変化させる施療子制御部41と、施療子制御部41により調整された刺激力が異なる刺激を与え、その時の複数の生体反応結果に基づいて、生体状態を判定する評価部42を備える。そして、評価部42は、被施療者の生体生理情報と、物理量情報とを組み合わせることにより身体の身体状態を検知する。【選択図】図3
