An application ProSupino was designed for android mobile phones and to collect in real-time forearm movement data from the tri-axial accelerometer while a subject develops with one of two series of pronation and supination movement tasks (PSMT_Flat or PSMT_Up). The results of a controlled study showed sensitivities and specificities larger than 85% in scaling of the primary motor symptoms, which suggests that ProSupino could be used to collect forearm motor related information on a daily.

A series of forearm pronation and supination motor tasks (FPSMT) has been developed to quantitatively assess various primary motor symptoms such as resting tremor, bradykinesia, rigidity, and posture disturbance using an accelerometer built into a smartphone, which is portable, comfortable and cost-effective. The FPSMT has two series of tasks, Flat and Up, which differ according to initial forearm posture. The results from 33 subjects including 6 PD patients showed sensitivities and specificities greater than 85% in rating of primary motor symptoms. This suggests that FPSMT could be used to collect forearm motor-related information on a daily basis, allowing for early diagnosis of patients with PD and also for constantly informing physicians about their patients' clinical status so as to quickly readjust and personalize treatment plans and minimize side effects.

A series forearm pronation and supination motor task, FPSMT is developed to quantitatively assess various primary motor symptoms such as resting tremor, bradykinesia, rigidity and posture disturbance using an accelerometer built in a smartphone, which is portable and comfortable and cost effective. The FPSMT has two procedures of tasks, "Flat" and "Up" according to the initial forearm postures. The result from thirty three subjects including six PD patients showed reasonable sensitivities and specificities.
