For lumbosacral radiculopathy there is a similarly low sensitivity; as few as 42% people with lumbosacral radiculopathy have abnormal EMGs compared to using MRI and clinical suspicion together as gold standard.23 The patients for whom to consider EMG for radiculopathy may be those with symptoms not correlating with imaging due to the high false-positive rate in imaging or when multilevel disease is present and the question is which level is affecting the patient most.
