Fig. 4From: Relationships between lumbar inter-vertebral motion and lordosis in healthy adult males: a cross sectional cohort studyCalculation of the maximum angular range reached during flexion (IV-RoMmax). Maximum angle of rotation reached by each inter-vertebral motion pair (A); Maximum motion frame rotation (B) (always 60° during the QF sagittal flexion examination). Note: Maximum inter-vertebral range of motion may not always be found at the end of motion frame movement rangeBack to article page
