This series has strived to define certain general principles that underlie almost all chiropractic adjustive technics. Parts I and II reviewed depth of drive, the articular snap, segmental distraction, timing, the advantages of placing the patient’s spine in an oval posture, correct table height, and patient positioning objectives.
Part III summarized the factor of time in the clinical approach and its underlying biomechanical principles of tissue viscoelasticity, fatigue, creep, and relaxation. Part IV and V reviewed the need to visualize the loading effects on articular cartilage, joint lubrication, action of the intra-articular synovial tabs, the articular planes, the fundamental types of contact, contact points and their options, securing the contact hand, and the direction of drive. Part VI offered a rationale on adjustive velocity, and this concluding column on this subject describes various types of adjustive thrusts.

Types of Adjustive Thrusts

Test Thrusts

Test thrusts are mild preliminary thrusts applied before an actual corrective thrust is delivered. They have a twofold purpose: first, to acquaint the adjuster with the structural resistance present and patient response to the pressure applied; second, to acquaint the patient with what to expect. Surprise lowers a patient’s pain threshold.
