Methods: This was a prospective study of 117 consecutive patients referred for hand symptoms. Each subject filled out a hand diagram of symptoms and had median and ulnar sensory and motor nerve conduction studies, includ- ing ulnar conduction across the elbow. Results: The best model for predicting an ulnar mononeuropathy included hand diagram scores of definite or possible. The model had a sensi- tivity of 50% and specificity of 93% with an ROC area of 0.90. Conclusions: The ulnar hand diagram scoring system can be useful as a screening tool in the electrodiagnostic laboratory or for epidemiologic studies. cal presentation and confirmed by electrodiagnos- tic testing. Clinically, an affected patient complains of numbness and tingling in an ulnar distribution. In more severe cases there is weakness and atrophy of ulnar innervated hand intrinsic muscles. There is a self-administered questionnaire that can be used to evaluate symptom severity (similar to the Boston questionnaire for CTS), but it has not been used to assess the prevalence of UN in the general population. 7
