Needle Examination

Perform needle exam on the symptomatic limb.  Test the minimum of one muscle innervated by the L2, L3, L4, L5 and S1 spinal roots (see Appendix C). Test the lumbosacral paraspinal muscles at one or more levels.

If abnormalities are detected, examine one or two additional muscles innervated by the suspected roots and different peripheral nerves.  Perform needle exam on the asymptomatic limb muscles for comparison as needed.
