Kinematic evaluation via portable sensor system has been increasingly applied in neurological sciences and clinical practice. However, conventional kinematic evaluation rarely extends the context beyond the motor impairment level. In addition, kinematic tasks with numerous items could be complex and time consuming that pose a burden to test applications and data processing. The study aimed to explore the correlation of finger-to-nose task (FNT) kinematics via Inertial Measurement Unit with upper limb motor function in subacute stroke. In this study, six FNT kinematic variables were used to measure movement time, smoothness, and velocity in 37 participants with subacute stroke. Upper limb motor function was evaluated with the Fugl-Meyer Assessment for Upper Extremity (FMA-UE), Action Research Arm Test (ARAT), and modified Barthel Index (MBI). As a result, mean velocity, peak velocity, and the number of movement units were associated with the clinical assessments. The multivariable linear regression models could estimate 55%, 51%, and 32% of variance in FMA-UE, ARAT, and MBI, respectively. In addition, age, gender, type of stroke, and paretic side had no significant effects on these associations. Results show that FNT kinematic variables measured via Inertial Measurement Unit are associated with upper extremity motor function in individuals with subacute stroke. The objective kinematic evaluation may be suitable for predicting clinical measures of motor impairment and capacity to understand upper extremity motor recovery and clinical decision making after stroke. This trial is registered with ChiCTR1900026656.
通过便携式传感器系统进行运动学评估已在神经科学和临床实践中得到越来越多的应用。然而，传统的运动学评估很少将评估范围扩展到运动损伤程度之外。此外，具有多项内容的运动学任务可能会很复杂且耗时，从而给测试应用和数据处理带来负担。本研究旨在探索基于惯性测量单元的手指触鼻任务（FNT）运动学与亚急性脑卒中上肢运动功能的相关性。在这项研究中，使用 6 个 FNT 运动学变量来测量 37 名亚急性脑卒中患者的运动时间、平滑度和速度。上肢运动功能采用 Fugl-Meyer 上肢评估（FMA-UE）、动作研究上肢测试（ARAT）和改良巴氏指数（MBI）进行评估。结果表明，平均速度、峰值速度和运动单位数量与临床评估结果相关。多元线性回归模型可以分别估计 FMA-UE、ARAT 和 MBI 的 55%、51%和 32%的方差。此外，年龄、性别、脑卒中类型和瘫痪侧对这些相关性没有显著影响。结果表明，基于惯性测量单元的 FNT 运动学变量与亚急性脑卒中患者的上肢运动功能相关。客观运动学评估可能适用于预测运动损伤的临床指标，以及对上肢运动恢复和脑卒中后临床决策的理解能力。本试验已在中国临床试验注册中心注册，注册号为 ChiCTR1900026656。
