Objectives: To evaluate therapeutic exercise-induced hemodynamic changes in patients with flexion- and extension-provoked low back pain (LBP).
Methods: Men with LBP (n=106) were divided into 2 groups: flexion-provoked LBP (n=61) and extensionprovoked LBP (n=45). The Japanese Orthopaedic Association (JOA) score, Visual Analogue Scale (VAS), SF-36 and intramuscular oxygenation measured by near-infrared spectroscopy on the paraspinal muscle during lumbar extension and flexion were evaluated at 2 and 4 weeks.
Results: Deoxygenated hemoglobin during lumbar flexion was significantly lower in flexion-provoked LBP than in extension-provoked LBP. VAS and the SF-36 domains of physical functioning, role physical, bodily pain were significantly improved in the flexion-provoked LBP group. Oxygenated hemoglobin during lumbar extensi.. View More»
