The gait rehabilitation platform for weight loss XY-K-G1 (hereinafter referred to as the training device) utilizes electric control for lifting the lifting column and managing the hoisting of the strap to reduce weight, thereby decreasing the weight of the lower limbs or lower back of patients. To enable patients to safely stand, walk, and train with gait, the training gradually strengthens the patient's lower limbs to support their ability to walk under their own weight.
