The invention relates to a
mass balancing device and method for a
lower limb rehabilitation training patient. The balancing device comprises a
reduced gravity generating mechanism, a bracket, an electric
winch, a steel
wire rope, a
pulley wheel, a
force sensor, a suspender, a running
machine and a
control system. When a
reduced gravity walking training is carried out, the patient wears the suspender to stand on the running
machine; the suspender is connected to the steel
wire rope through the
pulley wheel and two ends of the steel
wire rope are respectively mounted on the
reduced gravity generating mechanism and the electric
winch; and the size of the actual reduced gravity detected by the
force sensor is fed back to the
control system to realize closed-ring control. Aiming to the patient of
lower limb motor dysfunction caused by
central nervous system diseases including spinal injuries, brain
stroke and the like, a load to lower limbs of the patient which is caused by the self-gravity of the patient and the dynamic load in the walking process can be simultaneously relieved when the reduced gravity walking training is carried out, so as to realize constant-
mass gravity reduction. According to the
rehabilitation conditions of the patient or the training requirements, a weight reducing device provided by the invention can conveniently adjust a gravity reducing ratio. The suspender of the weight reducing device can be moved along the
gravity center of the patient in real time and is good for the
rehabilitation of normal physiological gaits of the patient.
