Proprioception informs the CNS about length, tension, and joint angle. It regulates feed-forward (anticipation) and feedback (correction).
Anticipatory Postural Adjustments (APA) pre-activate synergies based on the body schema. Faster APA (–25 ms) = –15% joint load (jump).
Ia afferents → reflex 40 ms; Ib Golgi → protective inhibition. Ensures early correction.
Afferents → cerebellum → motor cortex (80–120 ms) to adjust the subsequent movement. Suppressing proprioception ↑ variability by 30%.
Repetition strengthens spinal interneurons. Plyometrics = increased Ia gain, decreased drift.
Plantar neuropathy = slow detection, increased sprains. Torn ACL = altered APA, hip compensates.
Internal GPS: prepares action, detects errors, adjusts commands, shapes learning. Without it: balance and precision are lost.
Proprioception has become the most used and least understood word in the French-speaking movement field. And this ambiguity is not trivial. As long as it lasts, we prescribe in the fog. We see exercises. We don't see what they engage.
