Training of raters on use of the TRS would help standardize judgement.Īverage Spearmans correlation by tremor type composites Figures - uploaded by Mark A Stacy Author content All figure content in this area was uploaded by Mark A Stacy Content may be subject to copyright. It is best when the same rater performs repeated measures of tremor on a patient, particularly when judging tremor in handwriting and drawings. The average Spearman correlation was 0.87, indicating very good consistency between the two videotapes, but correlations for Part A were somewhat better than for Part B. Interrater reliabilities were greater for Part A items (magnitude of tremor in different body parts) than for Part B items (tremor in writing and drawings) of the TRS. In the interrater reliability evaluation, modified Kappa statistics for seven tremor type composites ranged from 0.10 to 0.65 in the first videotape and 0.17 to 0.62 in the second videotape.
