The Effect of Averaging Multiple Trials on Measurement Error During Ultrasound Imaging of Transversus Abdominis and Lumbar Multifidus Muscles in Individuals With Low Back Pain (original) (raw)

This research investigates the impact of averaging multiple trials on measurement error during ultrasound imaging of the transversus abdominis (TrA) and lumbar multifidus (LM) muscles in individuals experiencing low back pain. The findings reveal that using the mean of multiple measurements significantly improves intraexaminer measurement precision. However, limitations are noted, including the inability to generalize results beyond same-day assessments. The study emphasizes the importance of further research to understand and minimize measurement error and improve the reliability of ultrasonographic assessments in clinical settings.
