Hi everyone, my mom got the results of her emg and I don't have a clue how to read them. I figured if I posted them here you could help me. I am sorry this is so long but this is the doctors findings:
1) This is an abnormal study.
2) Both upper and lower extremity muscles shows diffused dennervation potentials with widespread fibrillation potentials and positive waves of all the muscle tested at both upper and lower exremeties. The left tongue shows fibrillation potentials as well. There are 4 muscles that show 1+ fasciculations which includes the left pronator terres, right flexor carpi radialis, left rectus femoris and right rectus femoris muscles.
3) The nerve conduction studies show axonal degeneration with demyelination of both peroneal and posterior tibial nerves, but the sensory conduction of both median and ulnar nerves was normal as well as the right sural nerve, except for the left sural nerve.
4) These electrodiagnostic studies is compatible with a motor neuron disease as it follows the electrophysiologic criteria of:
i. Wide spread fibrillation and positive waves in the upper and lower extremity
muscles with fasciculation of 2 muscles in the upper and lower extremity.
ii. The sensory fibers are not affected as the sensory conduction from both median
and ulnar nerves and the right sural nerves were normal.
iii. There is presence of fibrillation potentials for the left tongue.
iv. The motor nerve conduction studies showed slowing with the reduction of the
amplitude of the muscle action potential.
Once again I appreciate everyones input, you never let me down.
Thanks
Dana
