Estimating Disability in Patients with Essential Tremor: Comparison of Tremor Rating Scale, Spiral Drawing, and Accelerometric Tremor Power.

ABSTRACT:

Background

Although performance rating scales, spiral drawing, water pouring, and accelerometry are commonly used to assess tremor severity, the extent to which their results correlate with impairment in activities of daily living (ADL) remains unclear.

Objective

The aim was to identify the most effective predictors of ADL in essential tremor (ET).

Methods

Forty ET patients were examined using The Essential Tremor Rating Assessment Scale (TETRAS), spiral drawing, volume of water spilled, and accelerometric tremor power. Root-mean-square error, R², and F-test were calculated for models predicting TETRAS ADL subscore.

Results

TETRAS Performance Subscale explained the variability in TETRAS ADL with an R² value of 0.686. Models incorporating s
