We have developed a device, the Rehapiano, for the fast and quantitative assessment of action tremor. It uses strain gauges to measure force exerted by individual fingers. This article verifies the device's capability to measure and monitor the development of upper limb tremor. The Rehapiano uses a precision, 24-bit, analog-to-digital converter and an Arduino microcomputer to transfer raw data via a USB interface to a computer for processing, database storage, and evaluation. First, our experiments validated the device by measuring simulated tremors with known frequencies. Second, we created a measurement protocol, which we used to measure and compare healthy patients and patients with Parkinson's disease. Finally, we evaluated the repeatability of a quantitative assessment. We verified our hypothesis that the Rehapiano is able to detect force changes, and our experimental results confirmed that our system is capable of measuring action tremor. The Rehapiano is also sensitive enough to enable the quantification of Parkinsonian tremors.

使用应变片检测，测量和分析动作震颤。

我们开发了Rehapiano设备，用于快速定量地评估动作震颤。它使用应变仪测量单个手指施加的力。本文验证了该设备测量和监视上肢震颤发展的能力。Rehapiano使用精密的24位模数转换器和Arduino微型计算机，通过USB接口将原始数据传输到计算机以进行处理，数据库存储和评估。首先，我们的实验通过测量已知频率的模拟震颤验证了该设备。其次，我们创建了一个测量协议，该协议用于测量和比较健康患者和帕金森氏病患者。最后，我们评估了定量评估的可重复性。我们验证了Rehapiano能够检测到力变化的假设，并且我们的实验结果证实了我们的系统能够测量动作震颤。Rehapiano也足够敏感，可以量化帕金森氏震颤。
