To determine if pelvic posture, hip, and knee positions influence range of motion about the ankle joint.
Quasi-experimental repeated measures.
Biomechanics laboratory in a university setting.
Eleven men and six women free of ankle joint trauma.
Range of motion about the ankle joint.
ANOVA revealed a significant difference for position main effect on ankle joint range of motion (p=0.01). Post-hoc tests revealed that ankle joint range of motion significantly decreased as participants moved from flexion (i.e., 90 degrees hip and 90 degrees knee), to supine, and to long sitting (47.3 degrees , 38.8 degrees , and 16.4 degrees ; p<0.05). No significant differences were revealed for pelvic posture (p=0.64).
These findings indicate that pelvic posture may not influence ankle joint range of motion regardless of hip and knee joint positions. However, the combination of hip flexion and knee extension (i.e., long sitting) produces the greatest deficits in ankle joint range of motion.
确定骨盆姿势、髋关节和膝关节位置是否会影响踝关节的活动范围。
准实验性重复测量。
大学环境中的生物力学实验室。
11名男性和6名女性，无踝关节创伤史。
踝关节的活动范围。
方差分析显示，位置对踝关节活动范围的主效应存在显著差异（p = 0.01）。事后检验显示，随着参与者从屈曲位（即髋关节90度和膝关节90度）、仰卧位到长坐位移动，踝关节活动范围显著减小（分别为47.3度、38.8度和16.4度；p < 0.05）。骨盆姿势无显著差异（p = 0.64）。
这些发现表明，无论髋关节和膝关节位置如何，骨盆姿势可能不会影响踝关节活动范围。然而，髋关节屈曲和膝关节伸展（即长坐位）的组合会导致踝关节活动范围出现最大程度的减小。
