PROBLEM TO BE SOLVED: To detect an intention of standing as quickly as possible and support a standing movement at a suitable timing.SOLUTION: A standing movement support device according to one aspect of the present disclosure includes: a myoelectric acquisition part for acquiring a myoelectric value of an anterior tibial muscle of a sitting user and a myoelectric value of a lateral vastus muscle or a myoelectric value of a medial vastus muscle of the sitting user； an angle acquisition part for acquiring an angle at which the upper body of the sitting user leans forward； a detection circuit for detecting the start of a standing movement of the user on the basis of the myoelectric value of the anterior tibial muscle of the user, the myoelectric value of the lateral vastus muscle or the myoelectric value of the medial vastus muscle of the user, and the angle at which the upper body of the user leans forward； and a support part that starts support of the standing movement after the start of the standing movement.SELECTED DRAWING: Figure 1【課題】起立動作の意図をできる限り早く検出して、起立動作に適するタイミングで動作支援する。【解決手段】本開示の一態様に係る起立動作支援装置は、座っているユーザの前頚骨筋の筋電値と、座っているユーザの外側広筋の筋電値または内側広筋の筋電値とを取得する筋電取得部と、座っているユーザの上半身の前傾角度を取得する角度取得部と、ユーザの前頚骨筋の筋電値と、ユーザの外側広筋の筋電値または内側広筋の筋電値と、ユーザの上半身の前傾角度とに基づいて、ユーザの起立動作の開始を検出する検出回路と、起立動作の開始を検出した後、起立動作の支援を開始する支援部とを備える。【選択図】図１
