Feasibility of spirography features for objective assessment of motor function in Parkinson's disease

•A method for self-monitoring the motor function in Parkinson's disease is presented.•Slowness of movement (bradykinesia) is typically associated with under-medication.•Involuntary movements (dyskinesia) can be the result of over-medication.•A machine learning model that detects bradykinesia and dyskinesia is proposed.•The model's visual explanatory power is evaluated.
