What is Acceleromyography (AMG) NM monitoring?
muscle acceleration
237
What is Electromyography (EMG) NM monitoring?
muscle AP recorded;
| monitoring electrical activity proportional to muscle movement
238
What is Kinemyography (KMG) NM monitoring?
quantifies muscle movement with motion sensor strip
239
What is Mechanomyography (MMG) NM monitoring?
detects contraction force & converts it to an electrical signal
↑amplitude = ↑strength
240
What is Phonomyography (PMG) NM monitoring?
muscle contraction produces low frequency sounds; calculates muscle response
