Smart Trainer Arm Ergometry Exercise Training in Individuals Post-Stroke

Individuals with physical disabilities show much lower rates of exercise participation than their able-bodied peers. Much of the reason for the low rates of activity among this population comes from the presence of barriers. Lack of motivation, lack of transportation, lack of accessible facilities and equipment, and cost are all factors that discourage exercise participation among those with disabilities. Based on these factors, there is a need for accessible enjoyable exercise options for people with physical disabilities. The smart trainer ergometer (also known as the Advanced Virtual Exercise Environment Device) is comprised of an ergometer with foot and hand pedals, and a visual display in front of the user that can show a variety of scenic pathways.

In our previous protocol (IRB-300001384) we explored the power output curves of people post stroke compared with non-impaired individuals during one arm versus two arm cycling exercise using the smart trainer arm ergometer. The work demonstrated the potential benefit of interactive exercise for those with physical disabilities. The purpose of this study is to examine changes in power output, oxygen consumption, cognitive function, and quality of life after 8 weeks of smart trainer arm ergometry exercise training among individuals who have a stroke-based limb impairment.
