概括
患有帕金森病 (PwPD) 的患者和健康人群在控制步行速度时表现出类似的垂直地面反应力 (vGRF). 在曲线路径上,步行速度的降低在各组之间也相似,这突出了PwPD步行分析中速度正常化的重要性.
科学领域:
- 生物力学 生物力学
- 神经学 神经学
- 步态分析 步态分析
背景情况:
- 帕金森病 (PwPD) 是一种神经退行性疾病,影响运动控制.
- 步行障碍是PwPD的标志,但经常被减少的步行速度所混.
- 了解垂直地面反应力 (vGRF) 对于评估步态动态至关重要.
研究的目的:
- 为了比较PwPD和健康受试者 (HS) 之间的vGRF,同时控制行走速度.
- 调查线性与曲线性行走路径对两组vGRF的影响.
- 为了确定潜在的步态参数,使PwPD与HS有所区别,无论速度如何.
主要方法:
- 招募了18名PwPD和18名年龄和速度匹配的HS.
- 使用脚部压力内测量线性和曲线性行走时的vGRF.
- 在自选的步行速度收集数据,以确保自然的运动.
主要成果:
- PwPD和HS在曲线路径中表现出类似的行走速度.
- 在两种路径类型中,在PwPD和HS之间没有观察到vGRF的显著差异.
- 两组都在线性行走期间的初始接触和终端姿势时显示出增加的vGRF,并在曲线性行走期间的中间姿势时显示出增加的vGRF.
- 群体之间vGRF时间变化有所不同,特别是在终端位置.
结论:
- 当步行速度正常化时,PwPD和HS在曲线路径上显示了可比的vGRF模式和步行速度减少.
- 步行速度是评估PwPD步态动态时需要考虑的关键因素.
- 特定时间步行尺度的变化可能有助于将PwPD与HS区分开来,即使是在疾病早期阶段.

Parkinson's Disease: Overview
551
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...

Parkinson's Disease: Treatment

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.

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
