Mini joystick, Other proportional controls

•Mini joystick

This is pretty widely used among wheelchair users with SMA. If there is not enough strength or range present to use a standard joystick, the Mini may be a very appropriate alternative. It provides full proportional control (which is typically better, a more natural way to drive), and also allows access to all seat functions. Typically there is a need for a switch of some kind placed somewhere the user has

consistent motion, which acts as a “mode” switch to change between driving, speed change and power positioning/seat functions. Then, moving the joystick left and right, up or down will activate those functions and/or change the speed.

The user needs very little force and very little range to activate this joystick – in less than ¼” displacement you can achieve full speed and get acceleration and other variables for very accurate and refined driving. However, the user needs to be able to move in all 4 quadrants.

This joystick minimizes fatigue and enables many users with SMA to drive throughout the day. It is, however, quite fragile, so special care needs to be taken when transferring in and out of the chair, etc.

It can be placed anywhere around the body, and is often used with a mid line mount and good arm support.

•Other proportional controls

There are other alternatives, such as touch pads (which looks and works like a mouse pad on a laptop), and the Magitech (which is a small tilt sensor making the chair move towards the direction of tilt). With the appearance and popularity of the Mini, especially among people with SMA, their application has been reduced.

Digital control

Digital control is also referred to as switch control. The opportunities are endless – multiple switches and single switches of any size and shape. Switch control offers movement in 4 distinctive directions, 90° apart (forward, reverse, left, right). It is a good alternative if proportional driving is not possible – another alternative to achieve independence in mobility and potentially computer applications. Some therapists prefer digital controls as a training tool for first time drivers, assuming that it is easier to understand directionality through their use. Keep in mind, however, that proportional control provides a more natural (and usually faster) way of moving about.

•Multiple switches

The most frequently used multiple switch control is a head array. This device incorporates all switches into the headrest, and it is the movement of the head that controls the movement of the wheelchair. Most children with SMA may find this option fatiguing. Other switch controls available can be placed near the
