How are major bone and joint changes defined in biomechanical phases?

Major bone and joint changes are characteristic of phase 4 in the biomechanical phases. This phase signifies the advanced degenerative changes that occur as a result of prolonged and unresolved biomechanical stress. At this stage, the changes become significant and are often detectable through imaging studies, indicating a deterioration in function and structure.

Understanding the context of the biomechanical phases is crucial for recognizing the implications of spinal and joint health. In earlier phases, alterations may be less pronounced or reversible, which is not the case in phase 4 where the changes lead to more rigid structural adaptations and potentially chronic pain or dysfunction. This understanding emphasizes the importance of early intervention and treatment in chiropractic care to prevent progression into later phases where irreversible changes may occur.
