Which notation represents Type I dysfunction?

• A. L5 FRRSR
• B. L 1-5 NSRRL
• C. L5 FRSR
• D. L 1-5 FRSR

Answer: (B)

Type I dysfunction in osteopathic practice refers to a pattern of dysfunction characterized by a neutral position of the vertebrae, where the vertebrae can rotate and sidebend in opposite directions. This maintains the primary principle of the Type I mechanics, which involves the entire group of vertebrae as opposed to a single segment. The notation "L 1-5 NSRRL" indicates that the dysfunction involves the lumbar spine segments L1 through L5, and here "N" signifies neutrality, meaning the segments are in a neutral position rather than flexed or extended. The "SRRL" indicates that there is side bending to the right and rotation to the left, which is consistent with Type I mechanics where side bending and rotation occur in opposite directions for an entire group of vertebrae. Thus, this notation aptly captures the typical characteristics of a Type I dysfunction, making it the correct choice.
