The document discusses the selection of environmental control units (ECUs) in relation to client-centered care and assistive technology. It highlights key considerations such as the client's abilities, desired functions, environmental factors, and the importance of education and support to prevent abandonment. A person-centered approach is emphasized as essential for effective ECU selection and use.
Using the HAAT model to select an appropriate ECU for your client
- 1. ECUs Environmental Control Units: Selecting the right one for your client By Danielle I. Werner
- 2. 2 • COT Code of Ethics (2010) – the College is “committed to client-centred practice” (COT 2010:v) • Also see 3.3.2 (COT 2010:16) • NSF for Long-term Conditions – „Quality requirement 1: A person-centred service‟ (Department of Health (DH) 2005) • Adoption vs. abandonment – influenced by perceived relative advantage and involvement of client in choice (Reimer-Reiss and Wacker 2000) Personalised care – why? Danielle Werner - Assistive Technology
- 3. 3 • Assistive technology (AT) – any device, service, strategy or practice that is used as an aid in completing a task (Cook and Polgar 2008) • Augmentative and alternative communication (AAC) – AT used to overcome communication difficulties (Cook and Polgar 2008) • Environmental control unit (ECU) – a “device that allows control of appliances” (Cook and Polgar 2008: 548); AKA: • Environmental control system (ECS) • Electronic aid to daily living (EADL) Terms to know Danielle Werner - Assistive Technology
- 4. 4 Human Activity Assistive Technology (Cook and Polgar 2008) • Consider: • What movements and abilities are available • What the client wants to achieve • The client‟s level of expertise • What environments the client wants to have control in • The client‟s priorities!

- 5. 5 • Spinal cord injury at C5 due to skiing accident • Age 27 • Married • Lives in a large ground floor flat with ramp access, though currently in a temporary residence until modifications can be finalised • Wants to be as independent as possible in the home and needs a suitable ECU • Also intends to work from home Case study: Lorna Danielle Werner - Assistive Technology (Gille 2006)
- 6. 6 • Head, neck, some Physical shoulder movements Cognitive • Elbow flexion, not extension (Cook and Emotional Polgar 2008) • Diaphragmatic breathing, low stamina • Assistance in coughing and clearing secretions (Apparelyzed.com 2012) • Intact cognition • Depression post- accident, now motivated What skills and movements are available? Danielle Werner - Assistive Technology
- 7. 7 • Important factor of human aspect • „Novice‟ user first needs to grasp controls and learn to cope with limited function • „Expert‟ user can use unit creatively and unconsciously (Cook and Polgar 2008) What level of expertise does the client have? Danielle Werner - Assistive Technology
- 8. 8 • Direct selection When direct selection • Remote is not ideal… • Touchscreen • Scanning • Keyboard, modified • Switch • Directed scanning • Voice control • Row-column • Joystick scanning • Mouthstick • Coded access (e.g. • Eyegaze Morse code) • Etc. • Etc. Human-technology interface Test for the best! Danielle Werner - Assistive Technology (Liberator 2012)
- 9. 9 • Lights? • Doors? • Phone? Self-care • TV? • Computer? Productivity • Chair? Leisure • Etc. • What are the client‟s priorities? What must the ECU control? Danielle Werner - Assistive Technology
- 10. 10 • Home? Physical • Office or school? Social • Layout of environment • Number and position Cultural of outlets Institutional • ECU mounted on wheelchair? Controls? Display? • Wheelchair controls? • ALSO, what resources are available? In what environments will the ECU be used? Danielle Werner - Assistive Technology
- 11. 11 Signals • Direct wiring • X10 (via house wiring) • Wifi • Ultrasound • Infrared (IR) • Radio frequency (RF) Transmission Danielle Werner - Assistive Technology
- 12. 12 Client‟s priorities! Ongoing support • Aesthetics or • Progressive function? condition? • Speed, durability, batt • Novice expert ery life, reliability? • Change in priorities • Which functions • Change in needs should be at top of list or first page (depending on ECU)? Other considerations Danielle Werner - Assistive Technology
- 13. 13 (RSLSteeper no date) • RSLSteeper‟s evoassist and Remo Phone • Switch control using available movements (e.g. chin or mouth; Cook and Polgar 2008) • Typing stick for computer use (AbleData 2011) (Apparelyzed.com 2012) • Voice control (though not as main control) Choices for Lorna Danielle Werner - Assistive Technology
- 14. 14 • Appropriate education can help prevent abandonment • A „facilitator‟ should undertake training alongside client to assist during the learning phase • Information should be presented in small chunks so as not to overwhelm the client (Cook and Polgar 2008) • Ability to recall education also important indicator of adoption vs. abandonment (Wielandt et al 2006) • Education and support can come from other users who have had similar experiences (Spinal Injuries Association (SIA) no date) (Apparelyzed 2012) Education and support Danielle Werner - Assistive Technology
- 15. 15 TO CONCLUDE • Selecting the best ECU requires a person-centred approach • Appropriate selection reduces abandonment • Important considerations in selecting an ECU include: • Available skills and abilities of the client • Possible ways of interaction with an ECU • Desired functions • Environment, and the limitations of certain signals Danielle Werner - Assistive Technology
