Traumatic injury to neurons, initiated by high strain rates, consists of both primary and secondary damage, yet the cellular tolerances in the acute post-injury period are not well understood. The events that occur at the time of and immediately after an insult depend on the injury severity as well as inherent properties of the cell and tissue. We have analyzed neuronal plasma membrane disruption...
This paper describes the use of Virtual Reality in four projects within a Rehabilitation Engineering Research Center at the University of Southern California. The Research Center aims to develop and assess a range of technologies for people aging with and into a disability. One of the deliverables of this Center will be the development of a Virtual Rehabilitation Toolkit, a series of Virtual Reality...
It is important to evaluate closed-loop FES (functional electrical stimulation) control systems using standard time- and frequency-domain performance metrics to facilitate the discussion of results between research groups. Moreover, uniform reporting of the performance of control methods expedites the process of developing clinically useful controllers by concentrating research efforts on promising...
The prevalence of neurological disorders such as stroke, spinal cord injury and traumatic brain injury is increasing quickly in the industrialised societies. Although the benefit of the use of technology in rehabilitation and neurorehabilitation programs is proved, the presence of mechatronic systems is still very low. This paper proposes a new lower limb exoskeleton for functional rehabilitation...
Robot-mediated neurorehabilitation is a rapidly advancing field that seeks to use advances in robotics, virtual realities, and haptic interfaces, coupled with theories in neuroscience and rehabilitation to define new methods for treating neurological injuries such as stroke, spinal cord injury, and traumatic brain injury. The field is nascent and much work is needed to identify efficient hardware,...
The successful motor rehabilitation of stroke, traumatic brain/spinal cord/sport injured patients requires a highly intensive and task-specific therapy based approach. Significant budget, time and logistic constraints limits a direct hand-to-hand therapy approach, so that intelligent assistive machines may offer a solution to promote motor recovery and obtain a better understanding of human motor...
Successful motor rehabilitation of stroke, TBI and SCI subjects requires an intensive and task-specific therapy approach. Budget constrains limit a hand-to-hand therapy approach, so that intelligent machines may offer a solution to further promote motor recovery and to better understand motor control. This new field of automated or robot-assisted motor rehabilitation has emerged since the nineties...
Neurological diseases - such as spinal cord injury, stroke and traumatic brain injury - frequently result in gait impairment The recovery of the walking ability requires functional training (i.e. walking), as previous research in man and animal has shown. Because the patient usually has reduced voluntary muscle force early after the incident, his/her movements require external support by physical...
