Unique to wheelchairs, the diameter is generally 5cm smaller than the large rim. When hemiplegia is driven with one hand, add a smaller diameter for selection. The handwheel is generally pushed directly by the patient. If the function is not good, it can be modified in the following ways for easy driving: ⑴ Add rubber on the surface of the handwheel to increase the grinding force. ⑵ Increase the push handle along the circumference of the handwheel.
There are the following types of push handles ① Horizontal push handles. Used for C5 spinal injury. Therefore, the biceps muscles are sound, and the hand is placed on the push handle, and the cart can move forward by flexing the elbow. If there is no horizontal push handle, it cannot be pushed. ② Push the handle vertically. For rheumatoid arthritis when the movement of the shoulder and hand joints is limited. Therefore, the horizontal push handle cannot be used. ③ Thick push handle. It is used for patients with severely restricted finger movement and difficult to make a fist. It is also suitable for patients with osteoarthritis, heart disease, or elderly patients. (The hand-cranked wheelchair is driven by the hand instead of the handwheel)
