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 acts on inhibitory interneurons synapsing on the motoneuron pool of joint musculature, thus, the contractions created by the motoneuron pool decrease. [1]
Clinical Presentation[edit | edit source]
Quadriceps weakness following Anterior Cruciate Ligament Injury
Outcome Measures[edit | edit source]
- Voluntary Force Measurement
- The Hoffmann Reflex: It measures the motor neuron pool recruitment.
Management / Interventions[edit | edit source]
- Pharmacological Agents
- Exercise
- Cryotherapy [2][3][4]
- Neuromuscular electrical stimulation
- Transcutaneous electrical nerve stimulation
- Vibration
- Ultrasound
- Virtual Reality [5]
- Pressure biofeedback [6]
