The four Basic Hand Control System designs are:
- Push/pull: Push the control forward to brake; and pull back and hold to accelerate. Not the most popular control as it must be pulled toward you and held to maintain speed, requiring more arm strength.
- Push/twist: Like on a motorcycle, it requires twisting the handle for the gas and pushing the hand control lever for the brakes. Unlike the push/pull in that the driver doesn’t have to pull the lever back and hold to accelerate.
- Push/right angle: (Most popular) Drivers push forward for the brakes. Push down toward your thigh with a slight pull to your torso for acceleration. Acceleration with the push/right is less fatiguing than push/pull as the weight of your hand holds the desired speed.
- Push/rock: Not necessary to keep a grip on the control. The driver rocks his or her hand on the top of the handle, rocking back to accelerate and forward to apply the brakes, like a slot machine.
All four can be mounted on the right or left side depending on your preference or abilities.
