Behavior of the Lumbar Multifidus During Lower Extremity Movements in People with Recurrent Low Back Pain During Symptom Remission

Abstract

These data suggest that, during symptom remission, individuals with recurrent LBP, compared to healthy individuals, may have greater activity in at least some parts of the LM. Further investigation is required to determine whether the LM percentage thickness change observed in this study may be explained by differential changes in deep and/or superficial fibers of LM activity. This observation may have implications for clinical practice, but requires further investigation.
