Ultrasound Imaging: Intraexaminer and Interexaminer Reliability for Multifidus Muscle Thickness Assessment in Adults Aged 60 to 85 Years Versus Younger Adults

Abstract

Ultrasound imaging reliability for measurements of multifidus thickness at rest and during a CLL among older adults is consistent with previously published findings for younger adults. Among older adults, it may be preferable to have a single examiner conduct USI assessments.
