πLOWER BACK SERIES π DAY 3 - RANGE OF MOTION The lumbar spine can demonstrate four main types of motion β flexion, extension, rotation, and lateral flexion. This region generally shows 40-50 degrees flexion, 15-20 extension, 5-7 rotational, and 20 degrees lateral flexion. Flexion is generally limited due to soft tissue tension, whereas the other motions may be limited by either soft tissue tension or bony approximation. This is considered to be the global range of motion for the lumbar spine, with each segment having its own intervertebral range associated with it. Intervertebral range of motion varies by the segment, but it is generally representative of a equal distribution of the above ranges of motion.
