Interest in the study of physical activity among people with multiple sclerosis is increasing. Accurate measurement is critical when the relationships between physical activity and beneficial outcomes linked with disease progression, symptom management, and rehabilitation are being examined. Accelerometry is one way of objectively measuring physical activity in people with multiple sclerosis. The current study examined associations between rates of accelerometer counts and energy expenditure during walking in persons with multiple sclerosis and nondisabled controls. A strong linear relationship was found between accelerometer counts and energy expenditure, allowing for better quantification of physical activity behavior and its consequences in people with multiple sclerosis.
