RT Journal Article SR Electronic T1 Using and interpreting electrodiagnostic tests JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 671 OP 682 DO 10.3949/ccjm.87a.19154 VO 87 IS 11 A1 Matthew R. Ginsberg A1 John A. Morren A1 Kerry Levin YR 2020 UL http://www.ccjm.org/content/87/11/671.abstract AB Electrodiagnostic testing, consisting of nerve conduction studies and needle electrode examination, serves as an extension of a neurologic examination for evaluating a variety of focal and generalized neuromuscular conditions. By providing important clues on location, chronicity, severity, and pathophysiology, it can help to establish a diagnosis, evaluate the need for surgery, and assess patients who do not improve as expected after surgery.
