Feasibility RCT protocol evaluating a powered

Powered-wheelchair use improves participation for people with mobility limitations; however, many individuals do not receive powered-wheelchair skills training that meets their learning needs. The aim of this work is to evaluate the feasibility of a powered-wheelchair training program for older adults with cognitive impairment, using errorless learning strategies facilitated by shared control technology. A feasibility 2 × 2 factorial randomized controlled trial will recruit 32 older adults in residential care with mild to moderate cognitive impairment who are new powered-wheelchair use. The intervention consists of six or 12 training sessions, facilitated by shared control technology, using errorless learning techniques. Control participants will receive six or 12 training sessions using trial-and-error methods. Feasibility and clinical outcomes data (primary outcome: powered-wheelchair skills) will be collected. Errorless learning facilitated by shared control technology may be an alternative to meet the powered-wheelchair learning needs of older adults with cognitive impairments
