Bending forward or rounding your lower back is called flexion. Flexion in the lumbar spine is primarily limited by compression of the intervertebral disks and tension in the ligaments that run along the back of the spine. The normal range of movement of lumbar flexion is 40 to 50 degrees.he range of motion, or how far your spine can move, is limited by the disks between the vertebrae, the ligaments that tie the vertebrae together and the orientation of the facet joints on the back part of the vertebrae.
Axial hand rotation in the transverse plane occurs through pronation/supination of the forearm, not the wrist joint. The normal wrist range of motion is 65 to 80 of flexion, 55 to 75 of extension, 15 to 25 of radial deviation, and 30 to 45 of ulnar deviation. Most daily activities require a significant portion of the full range of wrist motion.
