Claim 5:
6. A load reduction method comprising:
calculating a ground reaction force load difference that is an amount of a load relief for a user, on the basis of a first measured value indicating a value at which a weight based on a weight of the user and a weight of a load reduction device that reduces a load on the user and has a mechanism that holds luggage and is at least worn by the user, is transmitted to a ground contact surface and of a second measured value indicating a value at which a weight based on the weight of the user is transmitted to the ground contact surface; and
controlling, on the basis of the ground reaction force load difference, torque that is output by a drive mechanism of the load reduction device to reduce the load on the user at a joint of each leg of the user.
