- Low back pain upon lumbar extension is frequently observed, measured at 60 to 75% of all back cases.
Indeed, it is almost normal (!!!) for those over 45.
- Low back pain upon lumbar flexion is also common, especially for men between the ages of 18 and 45 years.
- "Good body mechanics imply that all the joints of the body are used in such a position
in relation to their total range of motion that the possibility of further motion in either
direction - the factor of safety motion - is always present(2)".
