Reliability of lumbar multifidus ultrasound assessment during the active straight leg raise test.
Abstract
Previous evidence showed altered lumbar multifidus (LM) activation in populations with chronic non-specific low back pain (LBP). We aimed to investigate the test-retest and inter-examiner reliability of ultrasound imaging (US) for assessing LM thickness at rest and activation during the active straight leg raise test (ASLR) and the association between thickness changes with clinical outcomes.
