Assistive technology

Assistive technology (AT) is a term for assistive, adaptive, and rehabilitative devices for people with disabilities and the elderly. People with disabilities often have difficulty performing activities of daily living (ADLs) independently, or even with assistance. ADLs are self-care activities that include toileting, mobility (ambulation), eating, bathing, dressing, grooming, and personal device care. Assistive technology can ameliorate the effects of disabilities that limit the ability to perform ADLs. Assistive technology promotes greater independence by enabling people to perform tasks they were formerly unable to accomplish, or had great difficulty accomplishing, by providing enhancements to, or changing methods of interacting with, the technology needed to accomplish such tasks. For example, wheelchairs provide independent mobility for those who cannot walk, while assistive eating devices can enable people who cannot feed themselves to do so. Due to assistive technology, people with disabilities have an opportunity of a more positive and easygoing lifestyle, with an increase in "social participation", "security and control", and a greater chance to "reduce institutional costs without significantly increasing household expenses." In schools, assistive technology can be critical in allowing students with disabilities to access the general education curriculum. Students who experience challenges writing or keyboarding, for example, can use voice recognition software instead. Assistive technologies assist people who are recovering from strokes and people who have sustained injuries that affect their daily tasks.

A recent study from India led by Dr Edmond Fernandes et al. from Edward & Cynthia Institute of Public Health which was published in WHO SEARO Journal informed that geriatric care policies which address functional difficulties among older people will ought to be mainstreamed, resolve out-of-pocket spending for assistive technologies will need to look at government schemes for social protection.

Adaptive technology and assistive technology are different. Assistive technology is something that is used to help people with disabilities, while adaptive technology covers items that are specifically designed for disabled people and would seldom be used by a non-disabled person. In other words, assistive technology is any object or system that helps people with disabilities, while adaptive technology is specifically designed for disabled people. Consequently, adaptive technology is a subset of assistive technology. Adaptive technology often refers specifically to electronic and information technology access.

Occupational Therapy (OT) utilizes everyday occupations as a therapeutic tool for enhancing or enabling participation in healthy occupations to promote health and well-being (AOTA, 2020). Occupations include activities of daily living (ADLs), instrumental activities of daily living (IADLs), health management, rest and sleep, education, work, play, leisure, and social participation (AOTA, 2020).  "As occupational therapy professionals, we are uniquely trained to advocate for client-centered care that reduces barriers to participation in meaningful occupations and promotes overall well-being" (Clark, Iqbal & Myers, 2022)

OT practitioners (OTP) utilize assistive technologies (AT) to modify environments and promote access and fit to facilitate independence. For example, voice activated smart home technology allows an individual to control devices such as light switches, thermostat, oven, blinds, and music from their location.  OTP evaluate client's strengths and abilities and connects with desired tasks.  OTP help empower the client to match specific goals to AT tools. The theoretical approaches or frameworks OTPs frequently use to guide a client's AT choices may include: 1) The HAAT model by Cook, Polgar & Encarnaçāo (2015) 2) The interdependence - Human Activity Assistive Technology Model (I-HAAT) by Lee, et al. (2020); 3) The SETT Framework by Zabala (2005); or 4) The Unified Theory of Acceptance and Use of Technology (UTAUT 2) by Venkatesh, Thong & Xu (2012). Also, OTPs may seek advanced training through the Rehabilitation Engineering and Assistive Technology Society of North America (RESNA) organization to receive their Assistive Technology Professional (ATP) Certification and/or Seating and Mobility Specialist (SMS) Certification. Additional trainings and certifications may specialize in a focus area such as the Certified Assistive Technology Instructional Specialist for Individuals with Visual Impairments (CATIS™) (ACVREP, 2024).

Wheelchairs are devices that can be manually propelled or electrically propelled, and that include a seating system and are designed to be a substitute for the normal mobility that most people have. Wheelchairs and other mobility devices allow people to perform mobility-related activities of daily living which include feeding, toileting, dressing, grooming, and bathing. The devices come in a number of variations where they can be propelled either by hand or by motors where the occupant uses electrical controls to manage motors and seating control actuators through a joystick, sip-and-puff control, head switches or other input devices. Often there are handles behind the seat for someone else to do the pushing or input devices for caregivers. Wheelchairs are used by people for whom walking is difficult or impossible due to illness, injury, or disability. Ambulatory wheelchair users may also use other devices, such as walkers.

Newer advancements in wheelchair design enable wheelchairs to climb stairs, go off-road or propel using segway technology or additional add-ons like handbikes or power assists.

Patient transfer devices generally allow patients with impaired mobility to be moved by caregivers between beds, wheelchairs, commodes, toilets, chairs, stretchers, shower benches, automobiles, swimming pools, and other patient support systems (i.e., radiology, surgical, or examining tables).
