概括

脊髓损伤 (SCI) 改变了原发动皮层 (M1) 手部区域的刺激能力. 在SCI患者中,更大的M1手部区域运动唤起潜力 (MEP) 半球转换与改善四肢运动功能和日常生活能力相关.

科学领域:

神经科学是一个神经科学.
康复医学康复医学康复医学
发动机控制器的控制器

背景情况:

脊髓损伤 (SCI) 降低了原发动性皮质 (M1) 下肢区域的刺激能力.
在SCI患者的M1手部区域可能会对上肢和下肢编码信息.
手部M1区域皮质脊髓刺激 (CSE) 变化的特征在SCI后发生变化,它们的功能相关性仍然不清楚.

研究的目的:

为了调查SCI后M1手部区域CSE的变化.
在SCI患者中确定M1手部区域CSE和四肢运动功能/日常生活活动 (ADL) 之间的相关性.

主要方法:

对347名SCI患者和80名健康对照者的回顾性分析.
评估发动机唤起的潜力 (MEP) 作为CSE的衡量标准.
相关性和多重线性回归分析将MEP半球转换与运动功能和ADL联系起来.

主要成果:

SCI患者在主导半球M1手部区域表现出CSE降低.
在特定的SCI子组 (0-6个月,AIS A,非宫),M1手部区域MEP半球转换与运动分数和ADL正相关.
确定MEP半球转换是导致ADL变化的独立因素.

结论:

更高程度的M1手部区域MEP半球转换,更接近健康的对照水平,与更好的四肢运动功能和ADL有关.
调节双边M1手部区域刺激性,为SCI后的功能恢复提供了一个潜在的新策略.

Motor and Sensory Areas of the Cortex

Motor and Sensory Areas of the Cortex

The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and executing voluntary motor activities. This intricate structure is divided into three primary functional areas: the motor areas, sensory areas, and association areas.
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex....

Somatosensation

Somatosensation

The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.
