摘要

震颤是几种中枢和周围神经系统疾病的症状，如帕金森病(PD)。外骨骼已被研究作为药物和手术的非侵入性震颤抑制替代品。肌肉骨骼震颤抑制的挑战是在不妨碍患者自主运动的情况下衰减震颤运动。线性低通滤波器(lpf)通常用于震颤去除。本研究提出了一种基于自适应滤波器的替代方法。我们比较了lpf和自适应滤波器对在线数据库中记录的加速度信号的有效性。

A Real-Time Voluntary Motion Extraction Method Based on an Adaptive Filter

Tremors are a symptom of several disorders of the central and peripheral nervous systems, such as Parkinson’s disease (PD). Exoskeletons have been investigated as noninvasive tremor suppression alternatives to medication and surgery. The challenge in musculoskeletal tremor suppression is attenuation of tremor motion without impeding the patient’s voluntary motion. Linear low-pass filters (LPFs) are commonly used for tremor removal. This study presents an alternative method based on an adaptive filter. We compare the effectiveness of the LPFs and adaptive filter on the recorded acceleration signals from an online database.
