Abstract：
Boots are widely used by many people for various purposes, but their impact on gait biomechanics and injury risk is not well understood. This study investigated the effects of boots on walking biomechanics, compared to casual footwear. The lower limb joint kinematics and kinetics of 20 healthy male participants aged 20 to 30 years old were compared during self-paced walking with boots and shoes. The results showed that walking with boots is associated with greater hip extensor (P = 0.009) and ankle dorsiflexor (P < 0.001) moments in early stance, hip power generation (P < 0.001) and knee power absorption (P < 0.001) in early swing phase, hip abductor (P < 0.001) and knee adduction (P < 0.001) moments in the entire stance, net concentric work for the hip joint in sagittal (13.9%, P = 0.001) and frontal (21.7%, P = 0.002) planes. In contrast, the subtalar supinator moment in the entire stance (P < 0.001), ankle angular velocity in late stance (P < 0.001), and net concentric (- 42.7%, P < 0.001) and eccentric (- 44.6%, P = 0.004) works of subtalar joint were significantly lower in the boot condition. The compensatory adjustments in the hip and knee joints may result from ankle restrictions. While boots may aid those with ankle disorders, lower limb loading and the risk of musculoskeletal injuries and osteoarthritis could be increased. This study offers new perspectives on the biomechanical impact of boots on gait, potential prevention and treatment strategies of related injuries, and advancing footwear design.
摘要：
靴子被许多人广泛用于各种目的，但它们对步态生物力学和损伤风险的影响尚不清楚。这项研究调查了靴子对步行生物力学的影响，与休闲鞋相比。比较了20名年龄在20至30岁之间的健康男性参与者在穿着靴子和鞋子进行自我步行时的下肢关节运动学和动力学。结果表明，在早期站立时，穿靴子行走与较大的髋关节伸肌（P=0.009）和踝关节背屈肌（P<0.001）有关，髋部功率产生（P<0.001）和膝关节功率吸收（P<0.001）在早期摆动阶段，髋关节外展肌（P<0.001）和膝关节内收（P<0.001）的时刻，矢状髋关节的净同心工作（13.9％，P=0.001)和额叶(21.7%，P=0.002)平面。相比之下,整个姿势的距下旋肌力矩（P<0.001），站立后期踝关节角速度(P<0.001),和净同心(-42.7%，P<0.001）和偏心（-44.6%，P=0.004）在靴状态下，距下关节的功明显较低。髋关节和膝关节的补偿性调整可能是由于踝关节的限制。虽然靴子可以帮助那些患有脚踝疾病的人，下肢负荷和肌肉骨骼损伤和骨关节炎的风险可能会增加。这项研究为靴子对步态的生物力学影响提供了新的观点，相关伤害的潜在预防和治疗策略，和推进鞋类设计。
