Furthermore, a neck protection headrest is arranged at the position, close to the neck, of the adjustable chair back.
Furthermore, a waist protection pad is arranged at the middle part of the adjustable chair back, which is close to the waist.
Further, the pulley gear comprises a first linkage rod group, the left end of the first linkage rod group is connected with the front side and the rear side of the left end of the outer side wall of the connecting rod in a clamped mode, the right end of the first linkage rod group is hinged with a joint stimulation device, the outer side wall of the joint stimulation device is hinged with one end of a second linkage rod group, and the other end of the second linkage rod group is hinged with a pedal.
Furthermore, the other side of the knee joint is connected with a knee joint signal receiver.
Furthermore, elastic bands are fixedly arranged on the front side wall and the rear side wall of the pedal.
Another object of the present invention is to provide a control method of the knee neuromuscular training system, the control method comprising: improve patient's comfort level through setting up neck protection headrest and waist protection pad, the motion through first trace and second trace makes joint stimulation device send amazing signal, stimulates the knee joint, makes patient's shank be in the state of absolutely relaxing through setting up the running-board, receives the flesh electrical signal that the knee joint sent through setting up signal receiver, and then handles the flesh electrical signal that the knee joint sent, guarantees the precedence order of muscle contraction, and the action when the knee joint bends and stretches under the simulation normal condition.
By combining all the technical schemes, the invention has the advantages and positive effects that: the invention can not only generate the joint mobility, but also maintain the tension around the joint, and meanwhile, the mobility is generated by the muscle activity; the myoelectric signals of the healthy side leg in the knee stretching process are collected, then the same electric signals are output by adopting percutaneous nerve electrical stimulation on the affected side leg through data processing, the muscle contraction sequence is ensured, and the action of the knee joint in flexion and extension under normal conditions is simulated.
