✳Palm grasping training: connect the traction rope, select the appropriate weight value, and the palm rotates forward and backward by grasping cylinders of different diameters to train the patient’s grasping ability and wrist flexion and extension ability.

✳Forearm rotation training: connect the traction rope, select the appropriate weight value, hold the customized handle tightly and rotate clockwise or counterclockwise to train the patient’s forearm rotation range of motion.

✳Finger flexion and extension training: connect the traction rope, select the appropriate weight value, put the thumb on the rear fixed handle and the remaining four and a half fingers on the moving handle to do grasping and pinching exercise training towards the palm to improve the joint range of motion of the fingers and increase muscle strength.

✳Finger symmetry training: connect the traction rope, select the appropriate weight value, place the palm down on the hemisphere, tie the wrist with a strap, put the finger sleeve on the finger sleeve and do symmetrical back extension exercise training towards the back of the hand (the thumb and four fingers flex or extend symmetrically) to train the flexion and extension and muscle strength of the four fingers.

✳Finger pinching training: connect the traction rope, select the appropriate weight value, hold the round handle with the thumb and four fingers respectively to do grasping training, and train the pinching strength of the patient’s thumb and limbs.

✳Thumb strength training: connect the traction rope, select the appropriate weight value, put the thumb on the finger sleeve, and the other limbs are placed on the lower metal plate to pull the thumb downward to train the strength and mobility of the thumb.

✳Handle lifting training: connect the traction rope, select the appropriate weight value, hold the spherical device with the palm and pull it upward to train the patient’s hand vertical pulling force (lifting force).

✳Finger flat pull training: connect the traction rope, select the appropriate weight value, put the finger sleeve on the finger and pull it backward horizontally. By pulling different fingers, the patient’s hand horizontal pulling force is trained.

✳Finger grasping training: connect the traction rope, select the appropriate weight value, grasp the specially customized round ball with five fingers and rotate it clockwise or counterclockwise to train the patient’s grip strength and wrist rotation ability (flat rotation).

✳Wrist dorsiflexion and extension training: connect the traction rope, select the appropriate weight value, hold the front handle tightly with your hand (adjust the handle position to the appropriate position), fix the upper arm with a strap, and flex and extend the wrist to the left and right respectively to train the patient’s wrist flexion and extension range of motion.

✳Wrist ulnar deviation and radial deviation training: connect the traction rope, select the appropriate weight value, and use a special fixing device (stuck the traction rope in the front fixing hole, hold the handle tightly by hand to pull up for radial deviation, and clamp the traction rope in the rear fixing hole, and hold the handle tightly by hand to press down for ulnar deviation) to train the patient’s ulna and radius range of motion and wrist up and down training.

✳Forearm extension training: connect the traction rope, select the appropriate weight value, hold the handle with your hand, use the elbow as the fulcrum, lift and rotate the handle upward and put it down, train the patient’s forearm extension function and improve the elbow joint range of motion, and increase muscle strength.
