All tests were administered to all patients on each visit. Data collected included measures of sensory (monofilament, two-point discrimination, vibration) and motor function (grip, key-pinch, muscle atrophy), pain (visual analogue scale (VAS)) and impact on lifestyle (Levine's questionnaires (function status score - FSS, symptom severity score - SSS)), disability of the arm, shoulder and hand module (DASH) and patient-specific measures (PSM). Parametric and non-parametric correlation and factor analysis were done.<\/jats:p><\/jats:sec><jats:sec id=\"S0317167100001396_abs3\"><jats:title>Results:<\/jats:title><jats:p>Outcome analysis was available for 63 patient visits, with follow-up obtained for 20 patients (mean 8.5 months). Lifestyle and pain instruments (FSS, SSS, DASH, PSM and VAS) all correlated well with each other (r&gt; 0.6, p&lt; .01). DASH was moderately to highly correlated to nine of the 11 measures. Some tests correlated poorly, for example, Semmes-Weinstein monofilament with other sensory measures and muscle atrophy with almost all measures. Factor analysis revealed that there are two principal factors, accounting for 77% of the variance. Factor 1 relates to impact on lifestyle and pain while Factor 2 relates to strength and function.<\/jats:p><\/jats:sec><jats:sec id=\"S0317167100001396_abs4\"><jats:title>Discussion\/Conclusions:<\/jats:title><jats:p>Intraclass measures, particularly ones assessing lifestyle and pain instruments are strongly correlated. Factor analysis revealed two principal factors that account for the majority of the variance; future studies with a larger sample size are needed to validate this analysis.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s0317167100001396","type":"journal-article","created":{"date-parts":[[2014,12,12]],"date-time":"2014-12-12T15:38:34Z","timestamp":1418398714000},"page":"239-244","source":"Crossref","is-referenced-by-count":13,"title":["Prospective Analysis of Relationships of Outcome Measures for Ulnar Neuropathy at the Elbow"],"prefix":"10.1017","volume":"28","author":[{"given":"Catherine A.","family":"Munro","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rajiv","family":"Midha","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter H.","family":"Ho","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John Paul","family":"Szalai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jason","family":"Noble","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vivek","family":"Patel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2014,12,2]]},"reference":[{"key":"S0317167100001396_ref007","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199311000-00002"},{"key":"S0317167100001396_ref026","doi-asserted-by":"publisher","DOI":"10.1016\/S0266-7681(05)80125-1"},{"key":"S0317167100001396_ref014","volume-title":"Applied Nonparametric Statistical Methods","author":"Sprent","year":"1993"},{"key":"S0317167100001396_ref024","doi-asserted-by":"crossref","first-page":"71","DOI":"10.1080\/02844310050160204","article-title":"Assessment of functionaloutcome after nerve repair in a longitudinal cohort","volume":"34","author":"Ros\u00e9n","year":"2000","journal-title":"Scand J Plast Reconstr Hand Surg"},{"key":"S0317167100001396_ref018","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1973.38.6.0780"},{"key":"S0317167100001396_ref008","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(05)80089-9"},{"key":"S0317167100001396_ref023","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-4598(199808)21:8<1095::AID-MUS20>3.0.CO;2-S"},{"key":"S0317167100001396_ref006","doi-asserted-by":"publisher","DOI":"10.1016\/0266-7681(93)90247-D"},{"key":"S0317167100001396_ref020","volume-title":"Foundations of Behavioral Research","author":"Kerlinger","year":"1986"},{"key":"S0317167100001396_ref021","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-197052040-00009"},{"key":"S0317167100001396_ref013","first-page":"65","volume-title":"Diagnosis Of Nerve Injury.
