Reliability of a new scale for essential tremor
Open accessAbstract
Background: The objective of this study was to determine the reliability of a new scale for the clinical assessment of essential tremor. The Essential Tremor Rating Assessment Scale contains 9 performance items that rate action tremor in the head, face, voice, limbs, and trunk from 0 to 4 in half‐point intervals. Head and limb tremor ratings are defined by specific amplitude ranges in centimeters. Methods: Videos of 44 patients and 6 controls were rated by 10 specialists on 2 occasions 1–2 months apart. Inter‐ and intrarater reliability was assessed with a 2‐way random‐effects intraclass correlation, using an absolute agreement definition. Results: Inter‐ and intrarater intraclass correlations for head and upper‐limb tremor ranged from 0.86 to 0.96, and intraclass correlations for total score were 0.94 and 0.96. The intraclass correlations for voice, face, trunk, and leg were less robust. Conclusions: This scale is an exceptionally reliable tool for the clinical assessment of essential tremor. © 2012 Movement Disorder Society

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
