What effects does hypomobility have on the nucleus of the disc?

• A. Increased flow through the endplate
• B. Decreased flow through the endplate
• C. Strengthening of the nucleus
• D. Stabilization of the disc

Answer: (B)

Hypomobility refers to a decreased range of motion in a joint, which can significantly affect the biomechanics of the intervertebral disc. Within the disc, the nucleus pulposus relies on movement to help maintain hydration and nutrition through the process of diffusion. When a joint is hypomobile, the limited movement hampers the normal flow of nutrient-rich fluid into and out of the disc through its endplate. Decreased flow through the endplate results in insufficient nutrient exchange, leading to dehydration of the nucleus pulposus. This can contribute to degeneration and weakening of the disc structure, as the nucleus becomes less capable of absorbing shock and maintaining height, which is essential for the overall health of the spine. Therefore, understanding the relationship between hypomobility and decreased fluid flow is crucial for the assessment of disc health and the application of appropriate chiropractic care.
