Iliotibial band thickness: sonographic measurements in asymptomatic volunteers

PURPOSE: The aims of this study were to measure the thickness of the iliotibial band (ITB) in asymptomatic adult volunteers and to determine whether there was any correlation between these measurements and the subjects' age, weight, or height. METHODS: Sonography was used to measure the ITB thickness in 31 asymptomatic volunteers (13 men and 18 women) ranging from 25 to 68 years old. Two radiologists obtained the sonographic measurements of each volunteer at the levels of the femoral condyle and the tibial condyle of both knees. Findings of fluid or bursae adjacent to the ITB were recorded. RESULTS: The mean ITB thickness was 1.95 mm +/- 0.3 mm (+/- standard deviation) at the level of the femoral condyle and 3.4 mm +/- 0.5 mm at the level of the tibial condyle. There was a statistically significant negative correlation between ITB thickness and subject age. There was no significant correlation between ITB thickness and subject weight or height. Joint fluid was present in the lateral recess of both knees in 29 volunteers (93.5%) and 1 knee joint in 2 volunteers (6.5%). Bursae were present in 3 volunteers (9.7%). CONCLUSIONS: The mean sonographic values of normal ITB thickness established using sonography may be helpful in diagnosing ITB pathology. There is no significant correlation between ITB thickness and subject weight or height, but there is a negative correlation between ITB thickness and subject age. Joint fluid in the lateral recess is present in most asymptomatic individuals, but bursae are rare.     

Reliability of Real‐time Ultrasound Imaging for the Assessment of Trunk Stabilizer Muscles: A Systematic Review of the Literature

Rehabilitative ultrasound (US) imaging is one of the popular methods for investigating muscle morphologic characteristics and dimensions in recent years. The reliability of this method has been investigated in different studies. As studies have been performed with different designs and quality, reported values of rehabilitative US have a wide range. The objective of this study was to systematically review the literature conducted on the reliability of rehabilitative US imaging for the assessment of deep abdominal and lumbar trunk muscle dimensions. The PubMed/MEDLINE, Scopus, Google Scholar, Science Direct, Embase, Physiotherapy Evidence, Ovid, and CINAHL databases were searched to identify original research articles conducted on the reliability of rehabilitative US imaging published from June 2007 to August 2017. The articles were qualitatively assessed; reliability data were extracted; and the methodological quality was evaluated by 2 independent reviewers. Of the 26 included studies, 16 were considered of high methodological quality. Except for 2 studies, all high‐quality studies reported intraclass correlation coefficients (ICCs) for intra‐rater reliability of 0.70 or greater. Also, ICCs reported for inter‐rater reliability in high‐quality studies were generally greater than 0.70. Among low‐quality studies, reported ICCs ranged from 0.26 to 0.99 and 0.68 to 0.97 for intra‐ and inter‐rater reliability, respectively. Also, the reported standard error of measurement and minimal detectable change for rehabilitative US were generally in an acceptable range. Generally, the results of the reviewed studies indicate that rehabilitative US imaging has good levels of both inter‐ and intra‐rater reliability.
