This study aimed to investigate differences in gait patterns among individuals with different walking speeds and identify the range of motion (ROM) and angular velocity for various joints during gait. Forty-five schoolchildren were randomly selected for this study. To capture their walking patterns, two FDR-AX700 4K HDR camcorders were positioned to observe the predetermined walkway. Each participant completed a 5-meter walk at various speeds, including slow, normal, and fast, while maintaining a straight stride. There were significantly higher ROM and angular velocity (p<0.05) at the hip, knee, and ankle joints across most stages of walking at a faster speed compared to slow and normal speeds. At the same time, the angular velocity was significantly higher at the hip joint during hip extension terminal stance at normal speed compared to slow and fast speeds (p<0.05, ƞ =0.74). Similarly, the ROM of knee flexion swing, ankle plantar flexion loading response, and ankle dorsiflexion midswing angular velocity were significantly higher during normal walking speed (p<0.05). Conversely, slow-speed walking showed significantly higher ROM at knee extension terminal swing (ƞ=0.52) and ankle dorsiflexion terminal stance (ƞ=0.78) (p<0.05). The results indicate that individuals with different walking speeds exhibit significant differences in gait patterns. Slower walking speeds resulted in lower gait velocity and different joint motions compared to faster walking speeds.
本研究旨在探讨不同步行速度个体之间步态模式的差异，并确定步态过程中各关节的活动范围（ROM）和角速度。本研究随机选取了 45 名学童。为了捕捉他们的步行模式，两台 FDR-AX700 4K HDR 摄像机被放置在预定的步行道上进行观察。每位参与者以不同的速度（包括慢、正常和快）完成 5 米的步行，同时保持直线步幅。与慢和正常速度相比，在较快速度下，髋关节、膝关节和踝关节在大多数步行阶段的 ROM 和角速度显著增加（p<0.05）。同时，在正常速度下，髋关节伸展终末位时的角速度显著高于慢和快速度（p<0.05，ƞ=0.74）。同样，在正常步行速度下，膝关节屈曲摆动、踝关节跖屈负重反应和踝关节背屈中间摆动角速度的 ROM 显著增加（p<0.05）。相反，在慢速度行走时，膝关节伸展终末摆动（ƞ=0.52）和踝关节背屈终末站立（ƞ=0.78）的 ROM 显著增加（p<0.05）。结果表明，不同步行速度的个体在步态模式上存在显著差异。与较快的步行速度相比，较慢的步行速度导致较低的步行速度和不同的关节运动。
