项目摘要
This ongoing research program will provide a better understanding of how sensory information about contact with the environment is realized and utilized into functional balance reactions during locomotion. The long term objectives include substantial contributions to the understanding of the mechanisms of plantar-surface sensation use within human movement and also to inform the design of footwear, flooring and walking aids that involve, either directly or indirectly, plantar-surface sensation. The short term objectives of this proposal are 1) to determine the effects of reduced foot sensation states upon plantar pressure changes, the associated generation of lower limb muscle activity and joint moment/movement production during perturbed gait; 2) to determine the effect of facilitating plantar-surface sensation on plantar-pressure, the associated generation of lower limb muscle activity and joint moment/movement production during perturbed gait and 3) to model the mechanism of sensation/input of plantar pressure to functional responses using data from the two aforementioned objectives and data previously collected for the existing NSERC Discovery grant. Using synchronized measurement of pressure, force, motion and electromyographical data will investigate the effects of the loss of foot sensation and the potential for facilitation of foot sensation on dynamic balance during gait perturbations. The use of individual pressure measurement, electromyography and inverse dynamics to associate pressure to functional output (joint moments/movements) will greatly enhance the understanding of how contact pressure is utilized by the central nervous system. Secondly, the use of plantar-surface reduction/facilitation methods will permit identification of changes, due to reduction/facilitation in plantar-surface sensation, in muscular activity that produces functional balance reactions (joint moments/movements) to perturbations. These synchronized measurements of plantar pressure, muscle activity and joint kinetics will provide insight into how the CNS utilizes plantar-surface sensation information. These results will be used as the basis for potential interventions (facilitation insoles, predictive modeling (objective #3), footwear, flooring, etc.) to address the problem of falls in older adults (age-related) and patient populations (disease-related) due to their foot insensitivity.
这项正在进行的研究计划将提供一个更好的了解如何与环境接触的感觉信息是实现和利用到运动过程中的功能平衡反应。长期目标包括对人类运动中足底表面感觉使用机制的理解做出实质性贡献,并为直接或间接涉及足底表面感觉的鞋类、地板和助行器的设计提供信息。该建议的短期目标是1)确定减少的足部感觉状态对足底压力变化、下肢肌肉活动的相关产生和在扰动步态期间的关节力矩/运动产生的影响; 2)确定促进足底表面感觉对足底压力的影响,在扰动步态期间下肢肌肉活动和关节力矩/运动产生的相关产生,以及3)模拟感觉/运动的机制。使用来自上述两个目标的数据和先前为现有NSERC发现资助收集的数据,将足底压力输入到功能反应。使用同步测量的压力,力,运动和肌电图数据将调查的影响,失去脚的感觉和潜在的促进脚的感觉动态平衡在步态扰动。使用个体压力测量、肌电图和逆动力学将压力与功能输出(关节力矩/运动)相关联,将极大地增强对中枢神经系统如何利用接触压力的理解。其次,使用足底表面减少/促进方法将允许识别由于足底表面感觉减少/促进而引起的肌肉活动的变化,该肌肉活动产生对扰动的功能平衡反应(关节力矩/运动)。这些足底压力,肌肉活动和关节动力学的同步测量将提供洞察中枢神经系统如何利用足底表面感觉信息。这些结果将用作潜在干预措施的基础(促进鞋垫,预测建模(目标3),鞋类,地板等)。以解决老年人(与年龄相关)和患者群体(与疾病相关)由于其足部不敏感而导致的福尔斯跌倒问题。
