  author={Ji Hun Choi and Hyeo-Il Ma and Yun Joong Kim and Unjoo Lee},
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…

The detection of hand tremor through the characteristics of finger movement while typing

Typing data was analysed and it was showed that hand tremor in PD can be detected from keystroke features and the diagnosis of early PD through typing can achieve the clinical requirement of at least two cardinal features being present (bradykinesia and tremor).

High-accuracy detection of early Parkinson's Disease using multiple characteristics of finger movement while typing

Keystroke timing information was captured as subjects typed on a computer keyboard over an extended period and showed that PD affects various characteristics of hand and finger movement and that these can be detected.

This work compares quantitative measurements of hand tremor in twenty-three Parkinson's disease patients, with their clinical scores in theHand tremor components of the Unified Parkinson's Disease Rating Scale (UPDRS), which is considered the “gold standard” in the clinical assessment of the disease.

Validity and Responsiveness of At-Home Touch Screen Assessments in Advanced Parkinson's Disease

Correlations between OTS and clinical rating scales were adequate indicating that the test battery contains important elements of the information of well-established scales, and responsiveness and reproducibility were better for OTS than for total UPDRS.

High accuracy discrimination of Parkinson's disease participants from healthy controls using smartphones

This study objectively measure and quantify key movement severity symptoms of Parkinson's disease using consumer-grade smartphones with in-built accelerometers, and extracts a range of different features based on the time and frequency-domain properties of the acceleration time series.

Quantitative measurement of motor symptoms in Parkinson's disease: A study with full-body motion capture data

The experimental results indicate that the quantitative measure on spatio-temporal statistics learnt from the motion capture data reveal distinctive differences between mild and severe symptoms.

The initial findings indicate that new sensor technology and software algorithms can be effective in enhancing wearable sensor‐based system performance for monitoring PD motor disorders during unconstrained activities.

Inertial Sensing to Determine Movement Disorder Motion Present before and after Treatment

The results show that inertial sensors can be used to differentiate between effectivelymedicated PD motion and control motion; such a differentiation can often be difficult to perform with the human eye because effectively medicated PD patients tend to not produce much tremor.
