BACKGROUND
The treatment options for third-trimester musculoskeletal issues are limited. This study aims to examine how heel height affects gait biomechanics and provides heel height recommendations for various musculoskeletal problems.
METHODS
Five third-trimester gravidas were recruited wearing uniform footwear with four heel heights (0 mm, 15 mm, 30 mm, and 45 mm). Lower-limb muscle forces, joint angles, joint torques, joint contact forces, and ground reaction forces (GRF) at specific moments (the first peak, valley, and second peak of GRF) were collected for one-way analysis of variance with repeated measures.
RESULTS
The soleus, gastrocnemius, tibialis posterior, plantaris, obturator externus, gluteus maximus, gemellus superior, and obturator internus were the smallest at heel heights of 45 mm and 15 mm at the valley of GRF. Hip extension and knee flexion displayed the smallest joint angle and joint torques at a height of 15 mm. Ankle joint contact force decreased with increased heel height.
CONCLUSIONS
The height of the heel significantly impacts muscle force, joint angles, joint torques, and joint contact force. A heel of 15 mm might be the most suitable heel height to potentially avoid or alleviate musculoskeletal problems during the third trimester.
背景
孕晚期肌肉骨骼问题的治疗选择有限。本研究旨在探讨鞋跟高度如何影响步态生物力学，并为各种肌肉骨骼问题提供鞋跟高度建议。
方法
招募了五名孕晚期孕妇，她们穿着具有四种鞋跟高度（0毫米、15毫米、30毫米和45毫米）的统一鞋子。收集特定时刻（地面反作用力的第一个峰值、谷值和第二个峰值）的下肢肌肉力量、关节角度、关节扭矩、关节接触力和地面反作用力，进行重复测量的单因素方差分析。
结果
在地面反作用力的谷值处，比目鱼肌、腓肠肌、胫后肌、跖肌、闭孔外肌、臀大肌、上孖肌和闭孔内肌在鞋跟高度为45毫米和15毫米时最小。在15毫米的高度，髋关节伸展和膝关节屈曲显示出最小的关节角度和关节扭矩。踝关节接触力随着鞋跟高度的增加而降低。
结论
鞋跟高度显著影响肌肉力量、关节角度、关节扭矩和关节接触力。15毫米的鞋跟可能是孕晚期潜在避免或减轻肌肉骨骼问题的最合适鞋跟高度。
