Study Outcomes & Clinical Relevance: Like many other recent studies, this study confirms the importance of strengthening the lumbar extensors to improve symptoms in patients with chronic low back pain. Rectus abdominis strength is not compromised to the same degree in such patients and thus should be prioritized accordingly. Other contemporary studies fail to support the outdated notion that weak abdominals are of primary concern in the cause or treatment of low back pain.
