PROBLEM TO BE SOLVED: To obtain a device and method for controlling an exercise therapy apparatus in which an exercise load can be controlled by combining the constant speed load control with the constant watt load control, even if a leg strength of an exerciser is greatly different in left and right.SOLUTION: A device for controlling an exercise therapy apparatus is used by combining the constant watt load control with the constant speed load control. The device includes: constant speed load control units (31L, 31R) for performing constant speed load control of a load torque to left and right pedals independently in left and right, by holding and adjusting a rotational speed target value and a gain of left and right pedals independently in left and right and a switching units (34, 35) for determining whether to use any one of left and right of the constant speed load control based on information on the rotation torque to the pedals or the rotating position of the pedals by the pedaling of an exerciser, and switching between a rotational speed measured value and a torque target value.COPYRIGHT: (C)2016,JPO&INPIT【課題】運動者の脚力が左右で大きく異なる場合でも、等速度負荷制御と定ワット負荷制御とを併用して運動負荷を制御することができる運動療法装置の制御装置および制御方法を得る。【解決手段】等速度負荷制御と定ワット負荷制御とを併用する運動療法装置の制御装置であって、左右のペダルの回転速度目標値およびゲインを左右独立に保持および調整することにより、左右のペダルへの負荷トルクを左右独立に等速度負荷制御する等速度負荷制御部(31L、31R)と、運動者のペダリングよるペダルへの回転トルクまたはペダルの回転位置の情報を基に、等速度負荷制御の左右のどちらを使用するかを判別して、回転速度測定値およびトルク目標値を切替える切替器(34、35)とを備える。【選択図】図2
