| الملخص: | <h3>Purpose</h3><p dir="ltr">To monitor the progression of diseases such as Parkinson’s disease (PD) or essential tremor (ET), there is a growing interest in understanding their side effects and continuously monitoring the deterioration or progress of patients’ health conditions. The objective of this study was to investigate the feasibility of a wearable monitoring device constructed from compact MEMS for robust tremor detection in the upper limb using three different storage and monitoring techniques.</p><h3>Method</h3><p dir="ltr">Four subjects (2 PD and 2 ET) with varying stages of disease and treatment willingly provided offline, online, and live modes of tremor data using a low-cost, miniaturized accelerometer and microelectromechanical device.</p><h3>Results</h3><p dir="ltr">The results demonstrated differences in voluntary and non-voluntary characteristics of various activities and the distinct separation between them in the vibration spectrum at the limit of 2 Hz. Online and live monitoring provided the best alternatives to continuous in-home tracking combined with extensive post-processing techniques to detect tremor segments. The findings also highlighted the emergence of noticeable peaks, in the range between 3 and 8 Hz, for the PD’s frequency response, compared to the ET case, where the broadband behavior dominates.</p><h3>Conclusion</h3><p dir="ltr">The possibility of using a dynamic tuned mass damper tuned with dominant peaks to be canceled opens opportunities for PD passive tremor suppression.</p><h2>Other Information</h2><p dir="ltr">Published in: Journal of Vibration Engineering & Technologies<br>License: <a href="https://creativecommons.org/licenses/by/4.0" target="_blank">https://creativecommons.org/licenses/by/4.0</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1007/s42417-022-00734-2" target="_blank">https://dx.doi.org/10.1007/s42417-022-00734-2</a></p> |
