Dysfunction of the GM, in particular its functional subdivisions, is commonly implicated in lower limb pathologies. However, there is a lack of empirical evidence examining the role of the subdivisions of the GM. OBJECTIVES To compare the activation of the functional(More)
OBJECTIVE To estimate the criterion validity of accelerometer-based devices as measures of steps and energy expenditure in healthy controls and people with multiple sclerosis (MS) with varying disability levels during everyday activities. DESIGN Cross-sectional study. SETTING University research room. PARTICIPANTS People with MS who used at most a(More)
Accurate estimation of Energy Expenditure (EE) in ambulatory settings provides greater insight into the underlying relation between different human physical activity and health. This paper describes the development and validation of energy expenditure estimation algorithms. A total of 4 healthy subjects and 3 suffering from multiple sclerosis were monitored(More)
PURPOSE To investigate energy expenditure of people with multiple sclerosis (MS) during everyday activities. METHODS Fifteen healthy controls, 19 people with MS who used at most a stick to walk outdoors (MS-A), and 11 people with MS who used bilateral support for gait (MS-B) completed scripted everyday activities. A portable indirect calorimetry unit(More)
