It’s worth pointing out that there is a distinction between assistive and therapeutic technologies.

The same engineers, health scientists and entrepreneurs who develop and commercialize AT may be involved in designing and marketing devices for providers, e.g. PTs, OTs, MDs, SLPs, nurses, psychologists, recreational therapists and others to enhance their effectiveness in delivering rehabilitation services. An isokinetic exercise device or a hand dynamometer or a biofeedback system for treating speech anomalies – these are all examples of therapeutic technologies.

This distinction should not be drawn too rigidly however, since successful repeated execution of various activities, enabled or enhanced by AT can be therapeutic. For example, children with cerebral palsy who become capable independent ambulators through the use of AT, may also gain strength, sleep more soundly and be less prone to upper respiratory infections. In a very general sense, technology that enhances function and independence can always be seen as therapeutic in that it improves quality of life.
