Problems solved by technology

With the development of robotics technology, this rehabilitation process can be replaced by robots. At present, most of the leg rehabilitation robots are in the form of exoskeleton weight reduction, and the human body is suspended above the treadmill. This form requires a high space for the site and is not conducive to bed rest. The patient can perform rehabilitation training, while the existing leg muscle training device only uses the power of the motor to drive the leg, so that the leg muscles passively follow the movement of the motor to move, and when the patient's leg recovers to a certain extent, it is necessary to let the leg Rehabilitation of leg muscles with active movement

Abstract

The invention discloses a leg muscle trainer and a control method thereof. The leg muscle trainer comprises an outer frame, a crank, a crank shaft support, a pedal, a connecting rod, a rocker, a rocker support, a synchronous belt, a first synchronous pulley, a second synchronous pulley, a controller, a servo motor and a servo driver; the control method based on the device comprises the steps thatleg rehabilitation training is divided into a passive training mode that the servo motor provides power to drive leg movement and an active movement mode that the servo motor provides damping and needs legs to generate movement; bedridden patients can conduct leg muscle training and exercise leg joints on a sickbed, leg blood circulation is promoted, the passive mode and the active mode are alternatively used, the training method suitable for the patients can be adjusted continuously in the training process, and proper training mode adapting to the patients can be achieved in different rehabilitation phases.

Description

technical field [0001] The invention relates to a muscle training device and a control method thereof, in particular to a leg muscle training device and a control method thereof. Background technique [0002] Elderly people with weak legs, patients with movement disorders, and the disabled often lack exercise, and their legs will suffer from muscle atrophy and other problems. These people often rely on rehabilitation institutions for rehabilitation and exercise. Traditional gait rehabilitation is performed by experienced physical therapists and Provided by professional medical personnel, at least three physical therapists are required to work at the same time to monitor and assist the movement of the two legs. With the development of robotics technology, this rehabilitation process can be replaced by robots. At present, most of the leg rehabilitation robots are in the form of exoskeleton weight reduction, and the human body is suspended above the treadmill. This form require...
