In specific settings, the upper body trainer 500 includes a support plate 510 and a first servo motor 530 .

The support plate 510 is provided with a fixing member 511, and the fixing member 511 is used to fix the upper limb. Exemplarily, the fixing member 511 is an elastic cord, and two ends of the elastic cord are respectively opposite two sides of the support plate 510 .

A connecting member 570 and a second connecting member 590 are connected to opposite sides of the support plate 510 .

For patients in the early stage of training, limb movement is difficult, and the training intensity should not be too large. When the first servo motor 530 drives the support plate 510 to rotate, the direction needs to be changed continuously, that is, after turning to the left to the maximum angle, it is changed to turn to the right. Because the patient's upper limbs may have wounds or joints fractures, the upper limbs are easily turned over when changing directions due to inertia, which is extremely unfavorable for treatment. Therefore, in the early stage of treatment, the rotation speed of the first servo motor 530 is relatively slow, and the recovery effect of the patient's upper limbs is poor, resulting in a long training period.

The forearm with tight muscles will have better recovery effect during the rehabilitation training; In the process of rotation, the shoulder joint of the upper arm is close to the axis of rotation, and the angular velocity of the upper arm is smaller than the angular velocity of the forearm. In terms of rehabilitation training, the rotation speed has a greater impact on the forearm and is also the key to the rehabilitation effect. The rotation speed of the first servo motor 530 can shorten the rehabilitation training period.

In the specific setting, the opposite sides of the support plate 510 are respectively provided with a first sliding groove 513 and a second sliding groove, the first connecting member 570 can slide along the first sliding groove 513, and the second connecting member 590 can slide along the second sliding groove Slot sliding. In specific settings, the first chute 513 and the second chute are dovetail slots.
