Background summary
Musculoskeletal ultrasound (MSU) is an increasingly popular tool utilized by health care professionals. It is used on several steps of the clinical process and could be valuable for conditions such as low back pain. The lateral abdominal muscles and diaphragm play a crucial role in the etiology of low back pain and could be examined using MSU. However, the device remains user-dependent and aspects such as reliability must be examined in order to establish its role in clinical settings. Therefore, the aim of this study is to investigate intra- and inter-rater reliability of MSU when measuring the transverse abdominis (TrA), internal oblique (IO) and diaphragm thickness at 3 respiratory moments. An observational study will be conducted. The assessors will receive 20 hours of training. Sixty-five healthy subjects aged 18-29 will be included. Subjects will be evaluated in supine and during upright standing and at respiratory pause, full inhalation and maximal exhalation. Thickness measurements will be performed using relevant software. The intra- and inter-rater reliability will be calculated using intra-class correlation coefficients (ICC) and standard error of measurement (SEM).
Study objective
We hypothesize a good to excellent intra- and inter-rater reliability of measuring abdominal and diaphragm muscle thickness by ultrasound.
