METHOD AND SYSTEM FOR TREMOR ASSESSMENT USING PHOTOPLETHYSMOGRAPHY (PPG)

Existing wearable device-based approaches to capture tremor signal have accuracy limitations due to usage of accelerometer sensor with inherent noisy nature. The method and system disclosed herein taps characteristics of the PPG sensor of being sensitive to the motion artefact, as an advantage, to capture tremor signal present in the PPG sensor. The method disclosed herein describes an approach to extract tremor signal of interest from the PPG signal by performing a Singular Spectrum Analysis (SSA) followed by spectrum density estimation. The SSA comprises performing embedding on the acquired PPG signal, performing Principal Component Analysis (PCA) on the embedded signal and reconstructing the rest tremor signal from the significant principal components identified post the PCA. Further, the spectrum density estimation detects a dominant frequency present in the principal components, which is the dominant frequency associated with the rest tremor.
