Which of Fryette's laws refers to the motion of the spine when in the neutral position?

Fryette's First Law pertains to the motion of the spine in the neutral position, where the spine is neither flexed nor extended. It states that when the thoracic and lumbar spine segments are in a neutral position, there is a coupling of motion where sidebending of the vertebrae occurs in one direction, and rotation occurs in the opposite direction. This law is fundamental in osteopathic and chiropractic practices as it helps clinicians understand the mechanics of spinal movement and the implications for potential dysfunctions related to posture and spinal alignment.

Understanding this law is critical for clinicians when assessing and managing patients with spinal conditions, as it provides insight into how different segments of the spine interact during movement in a neutral posture. This knowledge can influence treatment strategies and help in developing effective rehabilitative exercises or manual therapy techniques.
