The Impact of Ulnar Nerve Compression at the Elbow on the Hand Function of Heavy Manual Workers
The objectives of this article were to study the impact of the hand function disability due to ulnar neuropathy at the elbow (UNE) on workers engaged in occupations requiring heavy hand use. Four patients (42.5 ± 7 years old), all engaged in heavy-duty jobs, with severe conduction block but without severe axonal loss were recruited. The severity of ulnar nerve compression was quantified based on electrophysiologic studies, Jebsen-Taylor Hand Function Test, Jamar dynamometer, and Semmes-Weinstein Monofilaments Test. UNE resulted in a reduction in hand strength without any significant impact on fine motor dexterity. The 4 laborers whose work required strong hand grip found this debilitating. Severe UNE affects the hand function of heavy manual workers by impeding their grip and pinch strengths. However, UNE does not affect tasks requiring fine hand dexterity.
