Perret, Claudio ; Berry, Helen ; Hunt, Kenneth J. ; Donaldson, Nick ; Kakebeeke, Tanja H.

In: Journal of Rehabilitation Medicine, 2010, vol. 42, no. 9, p. 873-875

Objective: To determine the functional electrical stimulated (FES) cycling volume necessary to reach the recommended weekly exercise caloric expenditure of 1000–2200 kcal in FES-trained subjects with paraplegia.Subjects: Eight (7 males, 1 female) FES-trained subjects with traumatic motor and sensory complete paraplegia (AIS A, lesion level between Th3 and Th9) of at least 3 years duration were...

Body-weight-supported robot-assisted devices can be used to promote gait rehabilitation and as exercise tools for neurologically impaired persons such as stroke and spinal-cord-injured patients. Here, we propose a novel feedback-control structure for real-time control of oxygen uptake during robot-assisted gait, in which we use the following methods. 1) A feedback-control structure is proposed,...
