Assistive Technology (AT) is:
“Any item, piece of equipment or product system, whether acquired commercially, off-the shelf, modified or customized, that is used to increase, maintain or improve functional capabilities of individuals with disabilities”
Simply put, Assistive technology is any product or service that makes tasks easier or possible.
What choices of AT are available?
There are many choices available for AT, from low tech and simple, to high tech and complex.
What types of daily activities and functions can be improved by using AT?
- Personal Care-Activities of Daily Living (ADLs)
- Independent Living-Instrumental Activities of Daily Living (IADLs)
- Avocation-leisure, recreation
- Education-benefit from instruction
- Employment-economic viability
- ‘Quality of Life’
How has AT benefitted people of different ages?
Studies have shown the following outcomes for many people of different age groups using AT:
- School age children able to remain in a regular classroom or reduce school-related services
- Working–age individuals able to reduce dependency on family members and paid assistants, or able to increase their earnings.
- Elderly individuals able to reduce dependence on others, reduce dependence on paid assistance or avoid entering a nursing home.
Do most people really use their AT devices?
Fifty percent (50%) of assistive technology is abandoned. In part this is a good news story – individuals get better and can do without. However, there is a large amount of money wasted due to preventable reasons:
- Failure to consider personal preferences and other options in choosing the AT device.
- Lack of training on how to use the device
- Lack of access to information about maintenance of the device
- Lack of knowledge about or access to needed repairs of the device
What needs to be done to better match the person and technology to each other and make sure it will really be used?
- Carefully identify functional needs and tasks to be addressed.
- Be specific and clear about the function you want to improve
- Consider getting a referral for a functional appraisal – e.g. from an assistive technology specialist, and from a medical practitioner for durable medical equipment (DME) or other medical devices.
- Look at the full range of options – low tech to high tech.
o Ask specific questions, go back for clarification, if needed.
o When possible, talk to others who have used the device.
- Give the likely options a trial run.
- Get appropriate training for use of the device.
- Make sure to learn about the necessary support systems – maintenance, troubleshooting, where to get repairs.
