American Association of Neuromuscular & Electrodiagnostic Medicine of Electrodiagnostic Medicine (ABEM) was created as an autonomous examining body that offered formal certification of competency in electrodiagnostic medicine. The ABEM examination is the only United States exam certifying physicians in EDX medicine, with more than 3,500 physicians currently certified. The ABEM certification process requires physicians to obtain specific academic training and clinical experience, then demonstrate competency in the EDX evaluation of neuromuscular and musculoskeletal systems by passing an examination. Diplomates of the ABEM are required to document their continuing education in electrodiagnostic medicine over the course of the ABEM Maintenance of Certification Program (MOCP) and take a maintenance
