In which joint mobilization technique is a large amplitude glide applied at the end of the range of motion?

In joint mobilization techniques, a large amplitude glide applied at the end of the range of motion is characteristic of Grade 3 Mobilization. This grade is specific to treatments aimed at increasing mobility and addressing resistance that is felt at the end of the available motion.

Grade 3 mobilization is designed to stretch the joint capsule and surrounding ligaments, providing more substantial movement than Grade 1 and Grade 2, which involve small amplitude motions. Those lower grades are typically used for pain relief and do not apply a force strong enough to reach the resistance barrier.

Grade 4 mobilization, on the other hand, involves a small amplitude movement performed at the very end of the available range, which is different from the large amplitude glide specified in this question. Grade 5, often referred to as manipulation, consists of high-velocity thrusts that aim to restore motion, but these are not characterized in terms of amplitude in the same way as Grades 3 and 4.

Therefore, identifying Grade 3 as the correct answer is based on understanding that it effectively uses a large amplitude glide to target the end of the joint's range of motion, promoting increased mobility through that resistance.
