Usually hear FDI fibers. sm

Subject: Usually hear FDI fibers. sm

See info.


 


Background: Electrodiagnostically, localization of ulnar nerve lesions, which commonly occurs at the elbow, is sometimes problematic. Measurement of motor ulnar nerve conduction velocity (NCV) at the elbow is amongst the most popular techniques to diagnose ulnar neuropathy. In this method, recording from the first dorsal interosseous muscle (FDI) is suggested to be more sensitive than the abductor digiti minimi (ADM). However, the criterion for abnormality is based on the normal values recorded from ADM. Aims: To determine the normal values of Ulnar motor NCV using FDI and ADM and the difference between the values obtained from FDI and ADM. Additionally, to measure the amount of reduction of NCV across the elbow for each recording site. Materials and Methods: This was a cross-sectional study performed on 50 healthy volunteers (100 nerves). All subjects were in the same condition regarding joint position and surface hand temperature. We recorded ulnar NCV at forearm and across the elbow with recording electrode on both FDI and ADM, simultaneously.

    Since there are so many different transcription platforms, you can't always program in the 1/2 symbol and typing it like that - 1/2 - is clumsy and can be unclear when read. The guidelines at my last in-house job were to convert it to decimal if possible.
