A right-angle hand control is typically indicated for clients with which condition?

Accepted Answer

Complete paraplegia with intact upper extremity function

Right-angle (push-right-angle) hand controls are commonly prescribed for individuals with paraplegia who have full upper extremity function and need to operate both brake and accelerator via a single lever.

Question 3

Which type of hand control operates the accelerator by rotating or twisting the handle?

A spinner knob with twist grip allows the driver to accelerate by rotating the grip, useful for those with limited hand strength or grip.
