According to Haldeman, how is subluxation defined?

B is the correct choice because Haldeman defines subluxation as an aberrant relationship between articular structures. This definition emphasizes that subluxation is not merely an anatomical misalignment but rather involves a complex interaction between the joints, including factors like joint motion, neurological function, and surrounding tissues. This broader understanding recognizes that subluxation can affect overall health and functioning, making it a crucial concept in chiropractic theory and practice.

Recognizing subluxation in this way allows practitioners to address not just the structural components but also the functional and biomechanical relationships that could lead to patient symptoms. The comprehensive nature of this definition aligns with the holistic approaches often taught in chiropractic care, where the focus is on ensuring the proper functioning of the nervous system, which can be compromised by these aberrant relationships.
