In which position are the vertebrae described as being in a neutral state?

The vertebrae are described as being in a neutral state when they are neither flexed nor extended. This position represents the natural alignment of the spinal column, where the vertebrae are stacked upon one another in a balanced way, allowing for optimal function and minimal strain on surrounding muscles and ligaments.

In the neutral position, the curvature of the spine maintains its natural shapes – the cervical lordosis, thoracic kyphosis, and lumbar lordosis – which are essential for absorbing shock and facilitating movement. This neutral alignment is foundational in osteopathic practice, as it allows for proper biomechanics and minimizes the risk of injury or dysfunction.

Flexion and extension involve movement away from this neutral state, which can lead to increased stress on the vertebrae and surrounding structures. Similarly, rotation introduces additional mechanical forces that can affect the spine's stability and function, making the neutral position the ideal baseline for assessment and treatment.
