What is a characteristic of Fryette Type II mechanics?

Fryette Type II mechanics describes the behavior of spinal segments when they are in a non-neutral position, specifically during flexion or extension. A key characteristic of this type of mechanics is that when one vertebra rotates around its axis, the adjacent vertebra, or vertebrae, move in the same direction. This is evidenced in the way the vertebrae interact during flexion and extension movements, where the coupled motion (rotation and lateral bending) occurs in a similar direction.

This principle is essential for understanding how the spine behaves during various motions and is fundamental for osteopathic evaluation and treatment strategies. In clinical practice, recognizing this behavior can help guide appropriate interventions for spinal dysfunction.

In contrast, the other options refer to conditions that either describe characteristics of Fryette Type I mechanics, which involve neutral positions and opposite directional movements, or suggest incorrect principles about spinal movement and correction strategies. The specificity of movement in the same direction within Fryette Type II mechanics is crucial for osteopathic assessment and treatment approaches.
