Quantitative assessment of Parkinson's disease with multiple wearable devices

With the aging of the population, Parkinson's disease (PD) is increasing and severely threating to human life and health. Quantitative assessment of the symptoms in PD is the key for precise diagnosis and treatment and essential for long term management over years. Currently, the evaluation of the symptoms in PD mainly relies on Unified Parkinson's Disease Rating Scale (UPDRS), which is affected by the subjective judgment of the clinicians. In this paper, we developed a new method for quantitative assessment of the motor symptoms in PD with multiple wearable devices. The method was used in conjunction with UPDRS assessment, and movement monitoring during sleep.
