Abstract

Background

Essential tremor (ET) is a common type of tremor. Previous research has shown that wearable orthoses and biomechanical loading methods can suppress tremors.

Objective

This study aims to investigate the effect of a harmonic liquid dampener on upper extremity ET.

Methods

The study involved 9 women and 5 men from a neurology outpatient clinic. A 285-g liquid-based harmonic dampening wristband was used. Tremors were recorded from the wrist along the x-y-z axes using a vibrometer, and the Bain–Findley Rating Scale (BFRS) was employed for assessment.

Results

BFRS scores significantly improved after the wristband was used (mean difference 35.64, P = 0.001, Cohen's d effect size =2.979). The tremor amplitude decreased significantly along the x-axis (Cohen's d: 1.35, P = 0.001), y-axis (Cohen's d: 3.232, P = 0.001), and z-axis (Cohen's d: 3.321, P = 0.001).

腕部谐波液体震颤吸收-阻尼对上肢原发性震颤的影响。

背景：原发性震颤（ET）是一种常见的震颤类型。先前的研究表明，可穿戴矫形器和生物力学加载方法可以抑制震颤。目的：本研究旨在探讨谐波液体阻尼器对上肢et的影响。方法：研究对象为来自某神经内科门诊的9名女性和5名男性。使用了285克的液体谐波阻尼腕带。用测振仪记录腕部沿x-y-z轴的震颤，并采用贝恩-芬德利评定量表（BFRS）进行评估。结果：腕带使用后BFRS评分显著提高（平均差异35.64,P = 0.001, Cohen’s d效应量=2.979）。地震振幅沿x轴（Cohen’s d: 1.35, P = 0.001）、y轴（Cohen’s d: 3.232, P = 0.001）和z轴（Cohen’s d: 3.321, P = 0.001）明显减小。结论：充液谐波阻尼腕带有望成为治疗ET患者的一种新的有效选择。©2025国际帕金森和运动障碍学会。
