Wheelchair wheels should have brakes on each wheel, of course, when hemiplegics can only use one hand.
I had to use the one-hand brake, but an extension rod can also be installed to control the brakes on both sides.

⑴ Notch brake. This brake is safe and reliable, but more laborious.
After adjustment, it can also be braked on slopes. If it is adjusted to level 1 and cannot be braked on flat ground, it will be invalid.

Its mechanical advantages are stronger than notched brakes, but fail faster.
In order to increase the braking force of patients, extension rods are often added to the brakes.
