Other Tests

See the list below:

  • The clinical syndrome is well defined, and further evaluation by electrodiagnostic studies may be unnecessary.

  • Evaluation with nerve conduction studies and needle examination electromyography (EMG) is warranted if no risk factors are identified, if a mass lesion in the retroperitoneal space is suspected, or if back pain also is present.

  • LFCN conduction studies can be technically difficult. When obtained, compare with the asymptomatic side.

  • The EMG should be normal in LFCN lesions, but the test is helpful in ruling out upper lumbar radiculopathy.
