概括
听觉线索可以帮助老年人和帕金森病患者修改步伐的长度和节奏. 适应式提示系统即使在双重任务的情况下也保持了步伐长度的变化,与固定的提示方法不同.
科学领域:
- 生物医学工程 生物医学工程
- 康复技术 康复技术 康复技术
- 神经科学是一个神经科学.
背景情况:
- 听觉线索用于老年人和帕金森病患者的步行康复.
- 目前的方法可靠地调整节奏,但不能调整步伐长度 (SL).
- 现有的算法缺乏个性化,适应运动波动,并在目标人群或双重任务场景中进行测试.
研究的目的:
- 开发和评估一种适应性听觉暗示框架,以调节步伐长度 (SL) 和节奏.
- 在单一和双重任务条件下,将适应性框架与固定提示方法进行比较.
- 确定影响适应性框架性能的因素.
主要方法:
- 使用多输出高斯过程 (MOGP) 开发了一个个性化的提示-响应模型.
- 实施了根据MOGP模型优化暗示选择的自适应性暗示策略.
- 在单一和双重任务条件下对13名老年人 (OA) 和8名帕金森病患者 (PwP) 进行了基准适应性与固定性暗示.
主要成果:
- 超过50%的OA和PwP证明了能够通过听觉线索改变SL和节奏的能力.
- 固定提示有效地改变了步态而不需要双重任务,但通过双重任务降低了SL修改.
- 适应性方法保持了SL修改的有效性,无论双重任务.
结论:
- 听觉线索可以有效调节老年人和患有帕金森病的人的步伐长度和节奏.
- 适应性提示为步行康复提供了强大的解决方案,特别是在双重任务条件下.
- 步态历史和暗示历史提高了自适应模型预测的准确性.

Parkinson's Disease: Treatment
268
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Parkinson's Disease: Overview
546
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...
