Abstract: A novel analytical methodology is presented aimed at the objective evaluation of dyskinetic movements which occur in Parkinson’s disease. The methodology is based on the comparison between the harmonic contents of voluntary and non-voluntary movements, highlighting their correlation in terms of frequency and phase mismatches. Interestingly, we demonstrated that there is a time delay between these two kinds of movements. The dyskinesia was measured by means of lowcost and easy-to-use wearable electronics based on inertial sensor units.
