摘要
Abstract
Objective To evaluate the usefulness of an ultrasonography-based method to examine quadriceps femoris contracting.Methods The thickness of bilateral rectus femoris (RF) and vastus intermedius (VI) and the cross-sectional area (CSA) of RF was measured in 10 healthy subjects (n= 20) in a relaxed position and 3 isometric contraction states using ultrasonography by two examiners. The date was compared with paired t test. Half of these subjects (n= 10) were also measured with MRI at rest. The date was also compared with paired t test. Results There was no significant difference between MRI and static compound ultrasonography, nor between two examiners. There was a significant difference (P＜0. 05) in thickness of RF and VI between relaxed and isometric contraction conditions. There was no significant difference among isometric contraction conditions. There was no significant difference among measurements of RF-CSA. Conclusion ultrasonography shows good validity and reliability in measuring quadriceps shape.关键词
