emg for posterior branch of brachial plexus

      I have been suffering from excruciating neck pain and have had an mri scan which reveales the intra vertebral disc  at the level of c4 c5 protruding into the foramen. Since actual compression of the nerve root cannot be shown on an mri the doctor suggested an emg of the brachial plexus to confirm compression.And here is where the shoe pinches.
Since I am having back neck pain compression of the root leading to poterior rami c4 c5 should be tested.But normal emg procedure is for the anterior rami.I have downloaded emg books from the net and there is no mention of posterior rami.
Can anyone help?


  • Sadly nobody here is able to provide any medical advice by the rules of the forum, and I'm not sure your question can be adequately answered without providing any medical advice or a medical assessment. My recommendation is to contact your doctor and see if he /she can address your concerns.
  • Hello,
           Thank you for your reply.Actually the muscles to be tested by inserting a needle ( as is done in emg) are the semispinalis capitis group of muscles which are supplied by the postererior rami of the lower cervical nerves.
    Could you just say emg involving postererior rami  of spinal nerves is possible or not?
    That won't be breaking the forum rules.
