Restoring normal walking abilities following the loss of them is a challenge. Importantly, there is a growing need for a better understanding of brain plasticity and the neural involvements for the initiation and control of these abilities so as to develop better rehabilitation programmes and external support devices. In this paper, we attempt to identify gait-related neural activities by decoding...
A hybrid neuroprosthesis is a device that uses a combination of electric motors and functional electrical stimulation (FES) to provide gait assistance. Its closed-loop control performance can be potentially affected by the presence of electromechanical delay (EMD) during FES. In this paper, a tracking control scheme for a hybrid walking neuroprosthesis that combines electric motor actuation at the...
Parkinson's disease (PD) is a neurodegenerative disorder and severely affects patients' daily lives. The diagnosis depends on the presence of one or more common motor symptoms of the disease. As PD is chronic and slowly progressive, the symptoms continue and worsen over a long period of time. Quantification of the PD's motor symptoms is helpful for diagnosing and monitoring patients' conditions. This...
Active lower limb exoskeletons can provide assistance to the lower extremities and may drastically improve the walking abilities of millions of individuals with gait impairments. However, most currently available control systems for these devices cannot predict the user's intended movements and have yet to enable walking with seamless transitions. Recent developments in intent recognition for active...
