Different handrail heights and initial foot angles are crucial to the performance of the STS movement. However, to the best of our knowledge, the effects of changing the toe orientation at different handrail heights on lower limb kinematics and dynamics have not yet been investigated. The purpose of this study was to investigate the comprehensive effects of different handrail heights on both sides and different initial foot angles on the kinematics and kinetics of healthy adults during the sit-to-stand movement. This study recruited 16 healthy young individuals, including 8 men and 8 women. The test was performed under seven conditions. The percent of movement time in each phase, the variation range of each joint angle of lower limb, and the joint moment of lower limb were analyzed and compared. There was an interaction between the handrail height and initial foot angle in relation to the percent of movement time in the fourth phase (P = 0.012). The initial foot angle had a significant effect on the variation range of the ankle joint angle (P = 0.016). The handrail height had a significant effect on the variation range of the hip joint angle (P = 0.019). During the sit-to-stand movement, individuals are able to stand and balance more rapidly under toe-middle under a high handrail than under other conditions. Toe-in under a high handrail may be more appropriate for patients with ankle joint injuries. High handrails should be preferred for those whose trunk cannot tilt forward sufficiently when leaving their seat.

不同的扶手高度和初始脚部角度对 STS 运动的性能至关重要。然而，据我们所知，在不同扶手高度下改变脚趾方向对下肢运动学和动力学的影响尚未得到研究。本研究旨在探讨不同两侧扶手高度和不同初始足部角度对健康成人坐立运动过程中运动学和动力学的综合影响。这项研究招募了 16 名健康的年轻人，包括 8 名男性和 8 名女性。测试在七种条件下进行。分析比较各阶段运动时间百分比、下肢各关节角度变化幅度、下肢关节力矩。扶手高度和初始足部角度与第四阶段运动时间百分比之间存在交互作用 (P = 0.012)。初始足角对踝关节角的变化幅度有显着影响（P=0.016）。扶手高度对髋关节角度变化幅度有显着影响（P=0.019）。在从坐到站的运动中，与在其他条件下相比，在高扶手下，个人能够在脚趾中间下更快地站立和平衡。在高扶手下前束可能更适合踝关节受伤的患者。对于离开座位时躯干不能充分前倾的人，应优先选择高扶手。初始足角对踝关节角的变化幅度有显着影响（P=0.016）。扶手高度对髋关节角度变化幅度有显着影响（P=0.019）。在从坐到站的运动中，与在其他条件下相比，在高扶手下，个人能够在脚趾中间下更快地站立和平衡。在高扶手下前束可能更适合踝关节受伤的患者。对于离开座位时躯干不能充分前倾的人，应优先选择高扶手。初始足角对踝关节角的变化幅度有显着影响（P=0.016）。扶手高度对髋关节角度变化幅度有显着影响（P=0.019）。在从坐到站的运动中，与在其他条件下相比，在高扶手下，个人能够在脚趾中间下更快地站立和平衡。在高扶手下前束可能更适合踝关节受伤的患者。对于离开座位时躯干不能充分前倾的人，应优先选择高扶手。与在其他条件下相比，在高扶手下，个人能够更快地站立和保持平衡。在高扶手下前束可能更适合踝关节受伤的患者。对于离开座位时躯干不能充分前倾的人，应优先选择高扶手。与在其他条件下相比，在高扶手下，个人能够更快地站立和保持平衡。在高扶手下前束可能更适合踝关节受伤的患者。对于离开座位时躯干不能充分前倾的人，应优先选择高扶手。
