A major drawback with current vehicle modifications is the inability to provide a practice session before driving on the road. Quantitative measurements obtained using a static assembly rig and a virtual driving scenario enabled appropriate adaptive adjustments for a client with post-polio syndrome who complained of difficulties turning the steering wheel. This study describes the assessment process, emphasizing the potential of the system, discussing the limitations of the evaluation and aims to offer occupational therapists an empirical perspective regarding vehicle adaptations for individuals with a physical disability.
