A study found that 82% of patients said the test was not as bad as they expected, and most patients noted only mild pain.8 It is important that referrals include clear descriptions of symptoms and a thoughtful diagnostic question for the electromyographer to evaluate (Box). 2017;55(2):149-159. I really do not know what this means exactly, but the results were awesome. Shivkumar C. Bhadola; and Kate M. Daniello, MD.

In PFPS, sEMG assesses vastus muscle inhibition or activation and is 70% specific and 84% sensitive, although an activity instability test has higher positive predictive value (100%) suggesting clinical diagnoses are equally or more useful.12 Surface EMG has been examined in patients with myofascial pain compared to normal control subjects, and a new technique showed accuracy to differentiate 60-85% of patients with myofascial pain from control subjects, suggesting there is inherent physiologic change to muscle in a state of pain.13 In contrast, a review article on sEMG activity in musicians, who have a high prevalence of musculoskeletal pain, found that sEMG utility varied, depending on which muscles were studied.14 Therefore, pain is not always associated with increased sEMG activity. Then the symptoms changed to having certain fingers feeling numb, I had to crack my knuckles to get some relief. Unfortunately, it seems that sEMG is not likely to be able to differentiate well between different causes of muscle pain.
