Most people who use a power wheelchair use a joystick; however, some drivers are unable to control a power wheelchair with this driving method. A wide variety of driving methods are available, including proportional and nonproportional driving methods. This course will present nonproportional driving methods, including head-controlled options, sip 'n puff, switch arrays (including mechanical, proximity, and fiber-optic), and eye gaze. Case studies are included. Clinicians need to be familiar with power wheelchair driving methods in order to participate in the evaluation process. This course will present specific power wheelchair nonproportional driving methods and clinical indicators for each.

Chapters & learning objectives

Nonproportional Driving Methods

1. Nonproportional Driving Methods

This chapter will present a definition and introduction to nonproportional, or digital, power wheelchair driving methods. Proximity and fiber-optic switches, clinical indicators, and mounting options will be presented.

Head Control

2. Head Control

This chapter will present driving methods that require good head control, including GyroSet, Magitek, and RIM. Head arrays that require fair to good head control will also be presented in the context of clinical indicators.

Sip ‘n Puff and Switch Control

3. Sip ‘n Puff and Switch Control

This chapter will present sip ‘n puff control and four switch arrays to provide independent mobility for clients who fit the clinical indicators for each. Any type of switch and switch site can be combined to meet an individual’s needs.

When Nothing Else Works

4. When Nothing Else Works

When nothing else works, it is possible to drive a power wheelchair with only one, two, or three switches. Specific options and clinical indicators will be presented. Eye gaze as a driving method will be included.
