Postural control: Studies into basic mechanisms re-training and neuroprosthetics

Back
Abstract:
One of the consequences of an injury or disease of the central nervous system (CNS) is impaired postural control and mobility. The impairment can range from moderate (hemiparesis, paraparesis, tetraparesis) to severe (hemiplegia, paraplegia and tetraplegia). The objective of the acute phase rehabilitation is to facilitate the recovery and development of alternative strategies and motor programs in impaired, which will enable them the accomplishment of various daily life activities. Frequently, however, these efforts needs to be complemented by an efficient neuroprosthetic system, augmenting the voluntary and reflex based actions of the impaired individual. Here, the question of appropriate control scheme arises as the actions of the neuroprosthesis needs to be concerted with the actions of the re-trained CNS. This question involves two inter-dependent processes: 1) re-training of postural control within the residual sensory-motor system in a way which will be compatible with the actions of the neuroprosthetics and 2) development of neuroprosthetics which will work in synergy with the re-trained CNS. This seminar will present an integrated and generic approach to restoration of efficient and functional postural control in a wide-variety of neurologically impaired individuals. The approach is based on the basic biomechanical mechanisms underlying balance control in neurologically intact humans applied to development of rehabilitation devices, balance assessment and re-training methodologies, and innovative control algorithms for neuroprostheses.
