Abstract: An assistance apparatus includes wires, each of which couples an upper-body belt and one of left and right knee belts to each other, and a motor. When the assistance apparatus assists a user in walking backward while carrying an object, the motor generates, in a gait phase of a left leg, a tension greater than or equal to a second threshold value in a second wire during a fifth period other than a first period during which a tension greater than or equal to a first threshold value is generated, and a tension less than the second threshold value in a first wire during a sixth period other than a second period during which a tension greater than or equal to the first threshold value is generated, and generates, in a gait phase of a right leg, a tension greater than or equal to the second threshold value in a fourth wire during a seventh period other than a third period during which a tension greater than or equal to the first threshold value is generated, and a tension less than the second threshold value in a third wire during an eighth period other than a fourth period during which a tension greater than or equal to the first threshold value is generated.

Abstract: An assistance apparatus includes a first wire and a second wire that couple an upper-body belt and a left knee belt to each other on or above a front part and back part of the body of a user, respectively, a third wire and a fourth wire that couple the upper-body belt and a right knee belt to each other on or above the front part and back part of the body of the user, respectively, a motor, a left sensor on the left hand of the user, and a right sensor on the right hand of the user. When a force is applied to the left sensor and no force is applied to the right sensor, the motor makes the tension of the second wire and the third wire greater than the tension of the first wire and the fourth wire. When a force is applied to the right sensor and no force is applied to the left sensor, the motor makes the tension of the first wire and the fourth wire greater than the tension of the second wire and the third wire.
