Can someone decifer this

EMG - would like to know what this means:

Findings:  Sensory nerve action potentials and compound muscle action potentials were all normal in the left upper extremity.  Concentric needle EMG evaluation (all left sided) noted no spontaneous abnormalities at rest in any muscle tested.  In the flexor carpi radialis, flexor digitorum sublimis, and to a lesser degree the biceps, were seen myopathic-appearing motor units (low amplitude, polyphasic) and in some areas, continuous dense firing of MEPs.  However, the degree of firing did seem to abate when I had the patient attempt to activate antagonist muscles.  Continuous MUPs were seen in the sternocledomastoid.  Needle study of the triceps and extensor carpi ulnaris were normal.  

Conclusions:  Abnormal study.  The findings in this needle study were suggestive of a myopathy.  In addition, there is evidence for continuous firing and generation of motor unit potentials that may be upper motor neuron or cerebrally initiated.

Thanks for using the forum. I am happy to address your questions, and my answer will be based on the information you provided here. Please make sure you recognize that this forum is for educational purposes only, and it does not substitute for a formal office visit with a doctor.

Without the ability to examine and obtain a history, I can not tell you what the exact cause of the symptoms is. However I will try to provide you with some useful information.

You should discuss the results with the physician who performed the test. It is difficult to give you much information. EMG’s are based on the experience of the physician and based on numbers generated. The physician’s interpretation is then obtained. The person who performed your test came to the conclusion that you have a myopathic process.

Again, please contact your phyisician to discuss the results.

Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck
