A body condition evaluation apparatus measures vicarious movement accompanying predetermined motion, and evaluates a physical condition of a body of a subject by using it as an index. A sensor unit 3L is mounted between a shoulder joint and a cubital joint of a left arm, a sensor unit 3R is mounted between a shoulder joint and a cubital joint of a right arm, a sensor unit 3C is mounted on a breast, and a sensor unit 3W is mounted on a navel. The respective sensors have a triaxial acceleration sensor 13. A movable range of the left arm is obtained on the basis of the sensor 3L, a movable range of the right arm is obtained on the basis of the sensor 3R, displacement widths of an upper body in a front-back direction and a right-left direction are obtained on the basis of the sensor 3C, and displacement widths of a lower back in a front-back direction and a right-left direction are obtained on the basis of the sensor 3W. For example, a difference between the right displacement width and the left displacement width of the upper body when raising the arms indicates a difference between the right vicarious movement and the left vicarious movement, and represents an extent of a defect of the shoulders.
