Environmental Control Units/Electronic Aids to Daily Living for People with Polytrauma
Environmental Control Units (also referred to as Electronic Aides to Daily Living ) are specialized assistive technologies designed to enable an individual to operate many household appliances and electronics if he or she can not use the standard controls. For example, if an individual can not access a standard light switch, an ECU could provide an alternative way for the individual to turn the lights on and off. Another example would be if someone had difficulty accessing and/or using the telephone. Once again, an ECU could provide a different way for the individual to use the telephone. ECU’s can also provide alternative controls for the television, cable box, DVD player, stereo, heating/air conditioning, fans, doors, etc.

FACTORS TO CONSIDER WHEN RECOMMENDING AN ENVIRONMENTAL CONTROL UNIT:
* Client’s Goals (what does he or she wish to control)
* What other assistive technology is utilized by the individual
* Client’s prognosis (stable/progressive?)
* Client’s cognition
* Where is the system going to be used (home or work, in one
room or throughout the house, etc.)
* System reliability, flexibility and ease of operation
* Local tech support for installation/configuration/service
* Expense of the system and the funding source
