背景情况:

晚期佩病 (LOPD) 是一种进展性神经肌肉疾病,导致显著的肌肉衰弱和功能衰退.
关于LOPD成年人运动缺陷进展的纵向数据有限.
由于肌肉衰弱,行走障碍和姿势不稳定,LOPD严重影响生活质量.

研究的目的:

量化两年来LOPD成年人肌肉力量,步态和姿势控制的变化.
为了确定最敏感的运动参数来跟踪LOPD的进展.
定义与LOPD相关的关键运动参数的临床重要差异最小值 (MCID) 值.

主要方法:

一项为期2年的纵向研究,涉及20名LOPD成年人和20名年龄相匹配的对照.
仪器和临床评估下肢力量,步态 (时空参数,性能) 和姿势控制 (摇摆速度,稳定性).
使用效果大小 (α) 和标准化响应平均值 (SRM) 分析参数响应度,对临床上有意义的变化定义了MCID.

主要成果:

患有LOPD的参与者在两年内显示出部延伸器/引器强度,膝盖曲器强度,脚脚下曲器强度,步行速度和姿势摇摆速度的显著恶化 (p < 0.009).
用动力仪测量部缩器/延伸器强度和步行速度是最容易发生变化的参数 (α > 0.55,SRM > 0.75).
绑架器强度,脚足底曲器强度和单肢姿势持续时间在LOPD患者中最高比例超过了MCID.

结论:

患有LOPD的成年人在两年内经历了显著的运动恶化,部肌肉疲软直接影响了步态和稳定性.
脚足部曲器对于在LOPD中保持谨慎的步态和平衡至关重要.
建议作为监测LOPD进展和评估干预措施的敏感生物标志物,建议使用部延伸器/绑架器强度和步行速度.

Parkinson's Disease: Overview

Parkinson's Disease: Overview

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

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.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Direct Motor Pathways

Direct Motor Pathways

The direct motor pathways, also known as the pyramidal tracts, are a group of neural pathways that originate in the brain and descend through the spinal cord. They control the voluntary movement of the body. There are two major direct motor pathways: the corticospinal and the corticobulbar tracts.
The corticospinal tract is responsible for the voluntary movement of the limbs and trunk. It originates in the cerebral cortex of the brain and descends through the cerebrum's internal capsule and...
