Background  Experiments can determine if nerve-specific patient-reported outcome measures (PROMs) can outperform regional or condition-specific PROMs. We compared a nerve-specific PROM of the upper extremity, the Impact of Hand Nerve Disorders (I-HaND) scale, to other validated measures quantifying activity intolerance and sought to assess interquestionnaire correlations and factors independently associated with activity intolerance and pain intensity. Methods  One hundred and thirty patients with any upper extremity nerve-related condition completed measures of demographics, psychological limitations, quality of life, activity intolerance, and pain intensity. To quantify activity intolerance, we used the I-HaND, Patient-Reported Outcomes Measurement Information System Physical Function Upper Extremity, and Disabilities of the Arm, Shoulder and Hand short form. Results  Strong interquestionnaire correlations were found between the activity intolerance measures ( r between 0.70 and 0.91). Multivariable analysis revealed that greater activity intolerance and greater pain intensity correlated most with greater symptoms of depression on all scales, with symptoms of depression accounting for 53 to 84% of the variability in the PROMs. Conclusion  There is no clear advantage of the nerve-specific I-HaND over shorter, regional PROMs, perhaps because they are all so closely tied to mental health. Unless an advantage relating to responsiveness to treatment is demonstrated, we support using a brief arm-specific PROM for all upper extremity conditions. Level of Evidence  Level II; Prognostic.
