Balance training apparatus and control program of balance training apparatus

A non-transitory computer readable medium storing a control program of a balance training apparatus in which a trainee who is standing on a moving cart that moves on a moving surface performs balance training, the control program causing a computer to execute the following steps:

• a center of gravity calculation step for calculating the center of gravity of loads of both feet of the trainee on a riding surface from a load detected by a detection unit mounted on the moving cart;
• a reference center of gravity setting step for setting the center of gravity of the loads at which it is estimated that the trainee has maintained an upright state on the riding surface as a reference center of gravity;
• an instruction control step for outputting an instruction of an orientation of a body to the trainee and an instruction to move the center of gravity to the trainee;
• and
• a control determination step for determining the orientation of the body of the trainee based on a change direction of the center of gravity of the loads from the reference center of gravity when the trainee has moved his/her center of gravity in the instruction output in the instruction control step and performing control to move the moving cart when it is determined that a result of the determination is appropriate.
