Many patients are discharged from neurorehabilitation focusing on motor control and ADL (activity of daily life ) training, while aerobic fitness training is neglected, especially in non-ambulatory patients. Randomized exercise training studies using a wide variety of modalities and protocols have demonstrated an 8~23% improvement in VO2peak after 2-6 months of training . However, most research recruit patients with hemiparesis who have mild-to-moderate gait impairment . No specific training protocols has been adequately studied or can be suggested for hemiplegic patients. It is difficult for them to partake in aerobic exercise, like walking or biking. There is a need to develop a new aerobic exercise module suitable for the patients, especially for those with ambulation difficulty resulted from severe paralysis.
