[0058] The steps of the present invention for patient rehabilitation training include: S1 (patient in position): The patient sits in front of the device and fixes the patient's forearm on the armrest with the handrest strap.
[0059] S2 (Training range calibration): The patient rotates to the limit according to his / her motor ability, and the control box component 2 maps the patient's activity range coordinate system to the game scene coordinate system according to the transposed matrix.
[0060] S3 (Set training parameters): The therapist selects the training mode and training parameters according to the patient's rehabilitation progress and exercise ability. The training modes include resistance, assisted, passive, stretching, isokinetic, isotonic, isometric, and relaxation modes. The training parameters include the output of the equipment and the speed of movement.
[0061] S4 (rehabilitation training): Rehabilitation training is performed according to the parameters set in S3. During the training, the present invention can also display the patient's wrist joint movement speed, movement mileage, output size, and participation. During the rehabilitation training process, the device protects the patient by limiting the training range, limiting the maximum torque, and detecting spasms to avoid sports injuries.
[0062] S4.1 (resistance mode): The present invention provides resistance, and the limbs resist this force to move, so as to restore and exercise active muscle endurance training. The present invention provides three resistance training methods: constant force, elasticity and inertia. Constant force resistance will always provide a constant resistance when the user moves, elastic resistance simulates the resistance of a spring, and inertia resistance simulates the movement scene of lifting heavy objects through pulleys and ropes.
[0063] S4.2 (Assistance Mode): The present invention provides auxiliary force to cooperate with and help the limbs to move, so that the limbs can perform continuous active training.
[0064] S4.3 (passive mode): The present invention assists the patient in completing rehabilitation training. In this mode, the device drives the patient to move toward the target position through trajectory planning, and the patient cannot drive the device to move toward a non-target point.
[0065] S4.4 (stretching mode): The present invention provides power, stops the movement at the boundary position and maintains it for a period of time to achieve passive training with stretching effect.
[0066] S4.5 (constant speed mode): The trainee actively exercises. When the exercise speed is greater than the set speed, the present invention provides resistance to ensure that the muscles contract at a constant speed.
[0067] S4.6 (isometric mode): The passive training of the present invention provides a holding force to stop the movement at the boundary position and maintain it for a period of time to achieve a stretching effect.
[0068] S4.7 (Isotonic mode): The present invention provides a constant tension to ensure that the muscle length changes while the muscle tension remains unchanged. Teaching mode: After the medical staff guides the operator to set a custom trajectory, the present invention will drive the patient's limbs to reproduce the trajectory.
[0069] S4.8 (relaxation mode): This is a training mode in which the present invention drives the limb joints to exercise. The power comes from the present invention. This mode moves at a low speed within a smaller range of motion.
[0070] S5: (Training ends, patient leaves): After the training ends, the present invention generates a training report according to the patient's movement during the training process, and the printer component prints the training report, and the therapist helps the patient leave the present invention.
