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.
Normal Range of Motion. Normal range of motion of the spine can vary, but a lack of it may contribute to the development of neck or back injuries. The average golfer should have normal range of motion of the spine in four directions.These can be assessed as follows: 1  Flexion: the golfer should be able to bend over at the hips and touch the mid-shin pain-free. 2  Extension: the golfer should be able to perform a mini back bend with hands on hips with no pain.aintaining normal range of motion of the spine during the swing will ensure proper posture at address, impact and follow through without requiring another body part to overdo. The normal range of motion needed at these points during the swing is as follows:
