Manipulation and Mobilization Lab

Shape a thrust or a slow mobilization and watch the joint gap, the sensors fire and the force curve trace itself; practise reading force time graphs; sort mechanisms by evidence and benefits from risks; and reason through clinic scenarios. This explains tissues and research, not how to perform any technique. Nothing here is graded.

Simplified teaching model with illustrative values. Joint gap is drawn from force above the preload (about 0.0015 mm per newton, exaggerated in the picture). Sensor firing rises with how fast force climbs, a pattern taken from animal studies. Cavitation appears when the rate of force is at least 1,500 N/s and the force climbs at least 150 N; that is a made up teaching rule, not a measured threshold. Real tissues, people and techniques vary a lot.
