概括
数字帕金森运动日记 (adPMD) 在跟踪晚期帕金森病的Off和Dyskinetic状态方面显示出中等有效性. 然而,与临床观察员数据的时间一致性仍然有限.
科学领域:
- 神经学 神经学
- 数字健康数字健康
- 可穿戴技术可穿戴技术
背景情况:
- 晚期帕金森病 (PD) 呈现出影响生活质量的运动波动.
- 目前用于PD运动波动的临床评级仪器具有偏差和错误.
- 可穿戴的数字健康技术为持续的运动波动监测提供了潜力.
研究的目的:
- 在现实条件下确定基于可穿戴加速计的数字帕金森运动日记 (adPMD) 的标准有效性.
- 为了将adPMD数据与临床检查 (黄金标准) 进行比较,用于监测PD中的运动波动.
- 与传统方法相比,评估adPMD在分类运动状态 (关闭,开启,失动) 中的准确性.
主要方法:
- 一项前性研究,涉及63名患有波动性PD的参与者,使用可穿戴加速度计 (adPMD).
- 连续的adPMD数据转换为关闭,开启和Dyskinetic状态,反映PD家庭日记.
- 使用临床检查作为黄金标准对标准有效性的分析,评估评审者之间的可靠性 (ICC,Cohen's κ).
主要成果:
- 在监测Off和Dyskinetic状态时,adPMD显示了中等有效性 (ICC = 0.43-0.51).
- 在adPMD和临床观察者之间,半小时的时间协议很差 (中位数Cohen的 κ = 0.13-0.21).
- 个性化adPMD值改善了Dyskinetic状态检测的时间协议,达到中等水平 (中位数Cohen的 κ = 0.25-0.41).
结论:
- 穿戴式adPMD监控每天捕捉到中等有效性的晚期PD中的Off和Dyskinetic状态.
- 在adPMD和临床观察者日记数据之间的时间一致性有限.
- 进一步完善adPMD算法可能会提高其对现实世界PD管理的实用性.

Parkinson's Disease: Overview
567
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.
