What does the instability hypothesis (Leach) suggest?

The instability hypothesis proposed by Leach emphasizes that both trauma and postural stresses can lead to misalignment and resultant instability in the spine. This perspective recognizes that structural integrity and proper alignment can be compromised not only through significant trauma but also through sustained mechanical stresses that arise from poor posture or repetitive movements.

The essence of the hypothesis is that a combination of factors contributes to spinal instability, rather than attributing this condition to a single cause. By acknowledging that both acute trauma and chronic postural issues play a role, the hypothesis supports a more holistic understanding of spinal health and the importance of considering various influences on alignment and stability. This aligns with the broader principles of chiropractic care, which focus on maintaining proper spinal alignment to promote overall health and well-being.
