Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology.

    概括

    惯性测量单位 (IMU) 显示,在行走过程中,创伤性脑损伤 (TBI) 患者的脚活动减少. 传感器位置对检测这些差异的能力以及它们与功能措施的关系产生重大影响.

    科学领域:

    • 神经科学是一个神经科学.
    • 生物力学 生物力学
    • 康复科学 康复科学 康复科学

    背景情况:

    • 创伤性脑损伤 (TBI) 经常导致感觉运动和步行缺陷.
    • 对身体活动的客观量化对于TBI康复至关重要.
    • 惯性测量单位 (IMU) 为活动监测提供了一个有前途的方法.

    研究的目的:

    • 评估TBI患者和健康对照患者在行走和爬楼梯时的IMU衍生活动水平.
