Cranial lateral strain is named based on the side-to-side shearing pattern of the sphenoid bone that occurs during this strain. In this particular strain pattern, the sphenoid moves in a way that reflects a lateral or sideways shear, which distinguishes it from other cranial motion patterns, such as flexion-extension or torsion. The specific naming convention indicates the side that is essentially the "dominant" side or the side that is experiencing more motion compared to the other.

Understanding this shearing mechanism is crucial for recognizing the impact it has on cranial dynamics and how these forces can affect other structures within the craniosacral system. The nature of the strain implies a deviation from normal movement patterns, making it pertinent for practitioners to appropriately identify and name the strain for effective diagnosis and treatment. This helps facilitate proper techniques during osteopathic manipulative treatment and ensures that the underlying biomechanical issues can be effectively addressed.
