As described in the previous two columns, all adjunctive procedures stand in the shadow of the basis for and the proper administration of the chiropractic adjustment. The goal of this series is to define briefly certain general principles that underlie almost all chiropractic adjustive technics. Some may be new to the reader, yet their basis is as old as chiropractic itself.

Parts I and II of this series reviewed depth of drive, the articular snap, segmental distraction, timing the thrust, the disadvantage of some drop-support tables, the advantages of placing the patient’s spine in an oval posture, correct table height, and patient positioning objectives. This column very briefly describes the factor of time in the clinical approach and its underlying biomechanical principles: viz, tissue viscoelasticity, fatigue, creep, and relaxation.

The Factor of Time in the Clinical Approach

To produce an effective articular adjustment, it is first necessary to evaluate the degree of joint motions and end plays present. Whatever corrective procedure is used, Hooke’s law should be remembered: The stress applied to stretch or compress a tissue is proportional to the strain, or change in length thus produced, if the limit of elasticity of the tissue is not exceeded. Adjustive ojectives are generally achieved by dynamic manual articular mobilization unless such a technic is contraindicated in a specific situation. Obviously, one would not apply a dynamic force over extremely porotic bone, a fracture, an abscess, a tubercular cyst, or a malignancy, for example; nor would it be applied over acutely inflamed tissue or splinted muscles if the doctor expects the patient to return.
