This study measured anatomic hip flexion angles (AHFAs) at specific and known mechanical hip flexion angles (MHFAs) (ie, seat-to-back angles) in order to determine the relationship between the two in the seated position. Six able-bodied children and 12 children with cerebral palsy were placed in eight different MHFA positions while AHFA was simultaneously measured. It was found that, although related, the hip flexion angle and the angle between the backrest and seat surface are not equal in most seated positions. The difference between AHFA and MHFA was greater in the children with cerebral palsy than in the able-bodied. The hip flexion angle of the child in the seated position should not be described as the angle between the backrest and seat surface or the angle of inclination of the backrest.
本研究测量了在特定且已知的髋关节机械屈曲角度（MHFAs）（即座椅与靠背角度）下的解剖学髋关节屈曲角度（AHFAs），以确定坐姿时两者之间的关系。六名健全儿童和12名脑瘫儿童被置于八个不同的MHFAs位置，同时测量AHFA。结果发现，虽然两者相关，但在大多数坐姿中，髋关节屈曲角度与靠背和座椅表面之间的角度并不相等。脑瘫儿童的AHFA与MHFAs之间的差异大于健全儿童。不应将坐姿儿童的髋关节屈曲角度描述为靠背与座椅表面之间的角度或靠背的倾斜角度。
