EDX | / the patient was evaluated in our centre but didn’t want to perform a new EDX as he felt totally fine | - normal interference pattern for deltoid, biceps and trapezius - outstanding increase of motor units number and of CMAP amplitude for SA | - very good increase of: motor units number with collateral reinnervation; and of CMAP amplitude for SA,IS; T; PQ - recovery limited by concomitant C6C7 root entrapment | / the patient was evaluated in our centre but didn’t want to perform a new EDX as he felt totally fine | - very good increase of motor units number and collateral reinnervation in left PQ, right SA and right IS - good but less significant increase of motor units in right PQ and left IS | - normal pattern in both T and right PQ - excellent increase of: motor units number with direct and collateral reinnervation; with normal CMAP amplitude for right SA, and both IS - 50% recovery of PN |
*HyperT1 signal: muscle fatty infiltration.
