Definition[edit | edit source]
Arthrogenic muscle inhibition (AMI) is the presynaptic, ongoing reflex inhibition of the musculature surrounding the injured joint. It is a natural response generated by the human body to protect the joint from further damage. [1]
Mechanism[edit | edit source]
Change in afferent input to the spinal cord from the joint mechanoreceptors (Ruffini endings, Pacinian capsule, Golgi tendon organ, Free nerve endings) appears to play a strong role in the mechanism of AMI. Following an injury, the joint mechanoreceptors activation act on inhibitory interneurons synapsing on the motoneuron pool of joint musculature, thus, the contractions created by the motoneuron pool decrease.
