Transducer‐based evaluation of tremor
Open accessAbstract
The International Parkinson and Movement Disorder Society established a task force on tremor that reviewed the use of transducer‐based measures in the quantification and characterization of tremor. Studies of accelerometry, electromyography, activity monitoring, gyroscopy, digitizing tablet‐based measures, vocal acoustic analysis, and several other transducer‐based methods were identified by searching PubMed.gov . The availability, use, acceptability, reliability, validity, and responsiveness were reviewed for each measure using the following criteria: (1) used in the assessment of tremor; (2) used in published studies by people other than the developers; and (3) adequate clinimetric testing. Accelerometry, gyroscopy, electromyography, and digitizing tablet‐based measures fulfilled all three criteria. Compared to rating scales, transducers are far more sensitive to changes in tremor amplitude and frequency, but they do not appear to be more capable of detecting a change that exceeds random variability in tremor amplitude (minimum detectable change). The use of transducer‐based measures requires careful attention to their limitations and validity in a particular clinical or research setting. © 2016 International Parkinson and Movement Disorder Society

Tremor is well suited to spectral analysis, the most popular method of tremor quantification, because of its oscillatory characteristics.
“Tremor is well suited to spectral analysis, the most popular method of tremor quantification, because of its oscillatory characteristics (113).”
From A Review on Wearable Technologies for Tremor Suppression (2021) · cites this paper as [113]
The Results sections on Accelerometry and Activity monitoring say spectral analysis is frequently used to estimate tremor amplitude and frequency and can distinguish oscillation from other movement. This supports its suitability for analyzing oscillatory tremor, but the paper does not establish that it is the most popular method of tremor quantification. (LLM, conf=0.85)

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.
