概括

发反射 (SR) 在原发性侧面硬化症 (PLS) 中明显比在肌缩性侧面硬化症 (ALS) 中更为普遍. 这表明SR可能是PLS和上部运动神经元占主导地位的ALS的新型临床标志物.

科学领域:

神经学神经学
神经科学是一个神经科学.
临床研究临床研究

背景情况:

有限的数据存在于初级侧面硬化症 (PLS) 中的震惊反射 (SR).
了解PLS中的SR对于差异诊断和疾病表征至关重要.
与肌缩性侧面硬化症 (ALS) 的比较可以提供宝贵的见解.

研究的目的:

调查PLS中SR的存在和流行情况.
为了比较PLS和ALS之间的SR发现.
探索这些运动神经元疾病的潜在临床标志物.

主要方法:

一项涉及46名PLS和54名ALS参与者的横截面研究.
使用结构化访谈来评估SR.
费舍尔的精确测试和多变量线性回归分析了患病率和关联.

主要成果:

与ALS (20.4%) 相比,PLS (93.5%) 的SR患病率明显高于ALS (20.4%).
在ALS中,在所有上部运动神经元 (UMN) 主导病例 (100%) 中观察到SR.
年龄较小,疾病持续时间较短,PLS诊断与更频繁的SR相关.

结论:

在PLS中,SR明显比ALS更常见.
在这两种情况下,占主导地位的UMN参与似乎是SR的关键.
在PLS和UMN占主导地位的ALS中,SR可能作为一种新的临床标志物,需要进一步验证.

关键词:

骨髓缩侧面硬化症 (ALS) 是一种疾病.主要侧面硬化症 (PLS)惊的反射反应开始.

Somatic Spinal Reflexes

Somatic Spinal Reflexes

Somatic spinal reflexes are rapid, involuntary muscular responses to external stimuli that involve the somatic musculature and the spinal cord.
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...

Reflex Activity

Reflex Activity

A reflex activity is an automatic, involuntary response to specific stimuli. It is a part of our survival mechanism, designed to protect us from potential harm. For example, when a bright light suddenly shines into our eyes, we instinctively close them or look away. This is a simple reflex activity orchestrated by the nervous system without conscious thought or effort.
A reflex exam is a diagnostic procedure performed by a healthcare professional to evaluate the functionality of a patient's...
