Improving mobility and community access in an adult with ataxia.

This case report summarizes the evaluation and treatment used to provide occupational therapy services to a man living with multiple sclerosis. Primary impairments included ataxia, paraparesis, and decreased endurance. The focus of this case study was on improving the client's ability to use powered mobility to access the community despite severe ataxia. A task-oriented approach was used as a frame of reference to guide the evaluation and intervention process. The primary goals of intervention were to control the degrees of freedom required for task participation and simultaneously increase postural stability, resulting in independent control of a power wheelchair. A combination of occupational therapy interventions is illustrated, including assistive technology, positioning, orthotic prescription, and adaptation of movement patterns.
