科学领域:

神经学神经学
运动生理学运动生理学
康复科学康复科学康复科学

背景情况:

多发性硬化症 (MS) 是一种慢性神经疾病,影响着运动和能量水平.
了解行走的能量成本对于管理MS患者的日常活动和生活质量至关重要.

研究的目的:

在被诊断患有多发性硬化症的个体中,研究走路与有氧能力相关的能量需求.
为了确定在这个人群中舒适地行走时的相对有氧负荷.

主要方法:

一项涉及45名患有多发性硬化症的参与者的横截面队列研究.
使用心肺运动测试测量有氧能力. 分析了6分钟步行测试中的能量需求.
相对有氧负荷被计算为步行能量需求与峰值氧气吸收和第一通风门的比率.

主要成果:

患有多发性硬化症的参与者平均相对有氧负荷为峰值容量的60%和第一个通风值的89.1%.
超过30%的参与者超过了他们的第一次呼吸门,这表明了显著的努力.
在相当一部分人群中观察到,峰值有氧能力降低 (45%) 和能源需求增加 (52%).

结论:

患有多发性硬化症的人在行走时表现出较高的相对有氧负荷,经常接近他们的第一个呼吸门.
这些发现突出了旨在提高多发性硬化患者有氧健身或减轻行走的能源成本的临床干预的潜力.

Multiple Sclerosis l: Introduction

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
