Intervertebral lumbar space and sciatic nerve thickness during flexion-distraction technique in asymptomatic participants – an exploratory study. - The Flexion-Distraction Technique (FDT) is used to mobilize the lumbar spine and relieve low back pain. However, there is limited evidence on the mechanisms underpinning this intervention. This study compared the intervertebral space between L5 and S1 (L5-S1) and sciatic nerve thickness at different FDT positions in an asymptomatic sample.
