What is Measuring ultrasound images of abdominal and lumbar multifidus muscles in older adults: A reliability study about?
Measurement reliability of the L4/5 lumbar multifidus (MF) muscles is high in older adults, but few studies have investigated measurement reliability of the abdominal and upper lumbar MF muscles in this age group. ## Objectives: To determine measurement reliability of abdominal and lumbar mf muscles from a single ultrasound (us) image in older adults. ## Methods: Resting thickness of rectus abdominis and obliquus externus, resting and contracted thickness of obliquus internus, transversus abdominis and lumbar mf, and resting cross-sectional area (csa) of mf levels (l2-5) were obtained from us images of 92 community-dwelling older adults (aged 65-89 years). measurements of images were undertaken by an experienced rater and repeated 7-10 days later for intra-rater, and by a second expert rater for inter-rater calculations. intra-rater reliability was estimated for all muscles. inter-rater reliability was estimated for all abdominal muscles and for l5 multifidus. reliability was estimated by intraclass correlation coefficients (icc). ## Results: Intra-rater icc(3,1) and inter-rater icc(2,1) of resting thickness measures of all muscles and csa of mf were ≥0.86. the iccs for percentage
