Fig. 3From: Does movement matter in people with back pain? Investigating ‘atypical’ lumbo-pelvic kinematics in people with and without back pain using wireless movement sensorsDelay (lag) of pelvic compared to lumbar movement. These graphs show ROM (Y axis) changes over time (X axis). Graph a was from a subject who moved their lumbar spine into flexion with a two second delay before the pelvis started moving. Graph b shows a more typical pattern with a synchronous start of movement of the lumbar spine and pelvisBack to article page
