MOESM1 of Integrated robotics platform with haptic control differentiates subjects with Parkinson’s disease from controls and quantifies the motor effects of levodopa

Additional file 1. Comparison of rigidity parameters (start/end total torques, hold torque, and peak speeds) derived from the passive stretch task performed over 600 ms and 1500 ms. A greater number of rigidity parameters were abnormal (i.e. failed in comparison to healthy subject performance) when faster stretches (600 ms) were used.
