The big wheels should have brakes for each wheel. Of course, when people with hemiplegia can only use one hand, they have to use one-hand brakes, but extension rods can also be installed to control the brakes on both sides.
There are two types of brakes: ⑴ Notch brakes. This brake is safe and reliable, but it is more laborious. After adjustment, it can also be braked on a slope. If it is adjusted to level 1 and cannot be braked on flat ground, it will be invalid. ⑵ Toggle brake. Using the principle of the lever to brake through several joints, its mechanical advantage is stronger than that of a notch brake, but it fails faster. In order to increase the braking force of the patient, an extension rod is often added to the brake, but this rod is easy to damage, and it will affect safety if it is not checked frequently.
Its height, depth, and width depending on the patient’s body type, and its material texture also depends on the type of disease. Generally, the depth is 41, 43cm, the width is 40, 46cm, and the height is 45, 50cm.
