In articulatory technique, what is the main principle?

• A. Fast, large-amplitude joint movements to quickly adjust.
• B. No motion to avoid tissue strain.
• C. Forceful thrust with high velocity.
• D. Slow, small-amplitude joint movements to restore joint play without causing tissue strain.

Answer: (D)

Articulatory technique is about restoring joint play with gentle, controlled motion. The idea is to apply slow, small-amplitude movements that are passive and stay within the joint’s available range. This lets the joint surfaces glide and the surrounding capsule and ligaments be gently stretched enough to overcome minor restrictions, without provoking tissue strain. Because the force and speed are modest, you’re more likely to improve the subtle arthrokinematic motions safely and gradually rather than risking irritation or injury. Fast, large movements or forceful thrusts can irritate tissues or overshoot what the joint can tolerate, and staying completely still doesn’t help re-establish the necessary joint glide.
