Unique to wheelchairs, the diameter is generally 5cm smaller than the large wheel. When hemiplegia is driven with one hand, a smaller diameter is added for selection. The hand wheel rim is generally directly driven by the patient. If the function is not good, it is easy to drive, and the following methods can be modified: ⑴ Add rubber on the surface of the hand wheel rim to increase the grinding force. ⑵ Increase the knob around the hand wheel. There are several types of push handles: ① Horizontal push handles. Used for C5 spine injury. Therefore, when the biceps are sound, the hand is placed on the handlebar, and the elbow flexion force can push the cart forward. If there is no horizontal push, it cannot be pushed. ② Push the handle vertically. Used when rheumatoid arthritis has limited shoulder and hand joint movement.

Therefore, the horizontal push bar cannot be used. ③ Bold push. It is used for patients with severely restricted finger movement and not easy to make a fist. It is also suitable for osteoarthritis, heart disease or elderly patients. (The hand-held wheelchair is driven by hand instead of the hand wheel)
