Multiple regression analysis of repetitive finger tapping parameters

In this paper, we present methodology for investigating relations among kinematic parameters of finger tapping, typically used for motor assessment of upper limb by implementing multiple linear regression analysis. Duration, speed and angle were selected as the most frequently used to describe taping performance. The goal of this study was to determine if these basic finger tapping parameters can be estimated through other parameters and to quantify their relations and contributions to the obtained estimation. The study included 12 patients with Parkinson's disease (PD) and 12, age and gender matched healthy subjects (HS). Results showed that selected three kinematic parameters can be estimated with error less than 7% for healthy subjects and less than 10% error for patients with PD.
