Very mild nerve entrapments do exist and may fail to meet the AMA Guides criteria for impairment related to a diagnosis of nerve entrapment.

..., the diagnosis of nerve entrapment can be made only by examining diagnostic test results. Consequently, without these electrodiagnostic studies, the physician cannot diagnose or rate nerve entrapment or compression. Postoperative nerve conduction studies are not necessary for impairment rating purposes (6th ed...

.... Electrodiagnostic physicians need to consult new data for motor and sensory conduction studies so CTS will not be overdiagnosed. 13 Has the diagnosis been made with reliable equipment? Some physicians have tried to incorporate more “cost effective” automated devices for measuring distal motor latencies...
