Abstract

Purpose

This study aimed to clarify age-related changes in the iliocapsularis (IC) using indicators of quantity, quality, and mechanical properties. We also compared the age-related changes in the IC and other hip muscles.

Methods

Eighty-seven healthy women (ages: 21–82 years, mean age: 45.9 ± 15.7 years) participated in the experiment. We measured thickness, echo intensity, and shear modulus of the IC, iliacus muscle, rectus femoris, and the thickness and shear modulus of the hip joint capsule. Spearman's rank correlation coefficient was used to measure the association of age with variables measured in the muscles and joint capsule.

Results

Thickness of the iliacus muscle and rectus femoris decreased significantly with age, but the thickness of the IC and hip joint capsule showed no significant correlation. The echo intensities of the IC, iliacus muscle, and rectus femoris were positively correlated, which increased with age. Furthermore, the shear modulus of the iliacus, rectus femoris, and hip joint capsule showed an increase with age, whereas the shear modulus of the IC exhibited no correlation with age.

Conclusion

The muscle quality of the IC changed significantly, unlike that of the iliacus or rectus femoris. Additionally, the correlation with echo intensity was relatively weaker in the IC compared with the iliacus or rectus femoris.

髂囊肌肉厚度、回声强度和剪切模量的年龄相关变化。

目的：本研究旨在通过数量、质量和机械性能指标来阐明髂囊（IC）与年龄相关的变化。我们还比较了IC和其他髋关节肌肉与年龄相关的变化。方法：87名健康女性（年龄21～82岁，平均年龄45.9±15.7岁）参加实验。我们测量了IC、髂肌、股直肌的厚度、回声强度和剪切模量，以及髋关节囊的厚度和剪切模量。Spearman秩相关系数用于测量年龄与肌肉和关节囊中测量变量的相关性。结果：随着年龄的增长，髂肌和股直肌的厚度显著下降，但IC和髋关节囊的厚度无显著相关性。IC、髂肌和股直肌的回声强度呈正相关，并随着年龄的增长而增加。此外，髂、股直肌和髋关节囊的剪切模量随着年龄的增长而增加，而IC的剪切模量与年龄无关。结论：IC的肌肉质量发生了显著变化，不同于股直肌或髂肌。此外，与髂或股直肌相比，IC与回声强度的相关性相对较弱。这篇文章受版权保护。保留所有权利。

期刊介绍： Clinical Physiology and Functional Imaging publishes reports on clinical and experimental research pertinent to human physiology in health and disease. The scope of the Journal is very broad, covering all aspects of the regulatory system in the cardiovascular, renal and pulmonary systems with special emphasis on methodological aspects. The focus for the journal is, however, work that has potential clinical relevance. The Journal also features review articles on recent front-line research within these fields of interest. Covered by the major abstracting services including Current Contents and Science Citation Index, Clinical Physiology and Functional Imaging plays an important role in providing effective and productive communication among clinical physiologists world-wide.
