The gold standard for evaluating Parkinson’s disease symptoms has primarily relied on subjective assessments during in-clinic visits using rating scales like the Unified Parkinson’s Disease Rating Scale (UPDRS). This approach, however, has specific limitations, leading to often incomplete disease progression evaluation. Over the last decades, various methods have been developed to assess the patients' motor symptoms more accurately.

Parkinson’s disease is a neurodegenerative disease without any curative treatment or neuroprotective or disease-halting drugs. It is characterized by motor symptoms that are still quantified mostly by subjective methods. Studies have shown that combining surface electromyography (EMG) and kinematic measurements can lead to objective quantification of a patient’s neuromuscular and motor function.
