Mechanism
Synthesis from 1 study
When a joint is pushed beyond its physical limit by heavy weight, it can't hold the position anymore — so the whole body shifts posture automatically to take the pressure off. This isn't a conscious choice; it's just physics: too much force makes the structure change shape to avoid breaking.
Most probable mechanism
When the force on a joint becomes too strong for it to handle, the body shifts its posture to reduce the stress on that joint, preventing it from breaking or giving way.
Applied external torque exceeds the maximum moment capacity of the joint, causing mechanical stress to surpass the structural resistance of surrounding tissues and connective structures.
Excessive joint stress alters the mechanical equilibrium of the musculoskeletal system, prompting involuntary redistribution of load through changes in limb alignment and muscle activation patterns.
Postural adjustment occurs as a passive mechanical response to torque imbalance, resulting in a new stable configuration where joint loading is reduced below failure thresholds.
