EP 3. Impact of energy expenditure and cognitive function on long- term outcome after stroke
Stroke leads to lesion-induced deficits like hemiparesis and aphasia. Furthermore patients suffer from low aerobic endurance and high energy expenditure of walking as well as from cognitive decline. Motor and Activity of daily living (ADL) rehabilitation might be negatively impacted by these factors. Here, our aim was to evaluate how (a) energy expenditure of walking and (b) cognitive function in the subacute phase after stroke correlate to long-term outcomes (gait speed, activities of daily life).

The Metabolic Cost of Exercising With a Robotic Exoskeleton: A Comparison of Healthy and Neurologically Impaired People
While neuro-recovery is maximized through active engagement, it has been suggested that the use of robotic exoskeletons in neuro-rehabilitation provides passive therapy. Using oxygen consumption (VO2) as an indicator of energy expenditure, we investigated the metabolic requirements of completing exercises in a free-standing robotic exoskeleton, with 20 healthy and 12 neurologically impaired participants (six with stroke, and six with multiple sclerosis (MS)). Neurological participants were evaluated pre- and post- 12 weeks of twice weekly robotic therapy. Healthy participants were evaluated in, and out of, the exoskeleton....

EP 84. Motor control and learning strategy for efficient neurorehabilitation
Parkinson ’s, stroke, and other neurological diseases may significantly affect the control of voluntary, ballistic-like movements that normally are performed automatically and optimally as regards position accuracy, energy expenditure and movement execution time. The control functions (neural signals to mus cles) are to be re-learnt and re-optimised with respect to these performance indices. In our study, a natural approach for efficient motor learning in goal-directed motion tasks, incl. walking is proposed.

On the Adaptation of Pelvic Motion by Applying 3-dimensional Guidance Forces Using TPAD
Pelvic movement is important to human locomotion as the center of mass is located near the center of pelvis. Lateral pelvic motion plays a crucial role to shift the center of mass on the stance leg, while swinging the other leg and keeping the body balanced. In addition, vertical pelvic movement helps to reduce metabolic energy expenditure by exchanging potential and kinetic energy during the gait cycle. However, patient groups with cerebral palsy or stroke have excessive pelvic motion that leads to high energy expenditure. In addition, they have higher chances of falls as the center ofmass could deviate outside the base o...
