| Outline of Final Research Achievements |
Objective: To clarify the sensitivity of ulnar nerve short-segment incremental study (SIS) and two optional nerve conduction studies (NCSs) for diagnosing ulnar neuropathy at the elbow (UNE) in comparison with routine NCSs. Materials and Methods: The sensitivity and specificity of SIS, motor NCS recording from the forearm muscles (forearm MCS), orthodromic mixed NCS (MNCS) in comparison between ulnar nerve vs. median nerve, and routine NCSs performed for clinically diagnosed cases with UNE were compared. Results: Totally, 50 healthy arms and 24 arms with UNE were studied. The UNE group was divided into severe and mild groups. All NCS specificities were acceptable (96%-100%). SIS recording from the first dorsal interossei (FDI) had a significantly higher sensitivity than routine motor NCS (83.3% vs. 54.2%, p < 0.05). Forearm MCS in the severe UNE hand group (n=12) and MNCS in the mild group (n=12) had identical or better sensitivity than routine NCSs.
