Segmentation of the Digitizer data. DOCX Abstract Objective To assess whether standardized handwriting can provide quantitative measures to distinguish patients diagnosed with Parkinson's disease from age- and gender-matched healthy control participants.

Parkinson patients were tested after overnight withdrawal of anti-Parkinsonian medication. Main Outcome Measures Movement time and velocity to detect bradykinesia and the size of writing to detect micrographia. A rest recording to investigate the presence of a rest-tremor, by frequency analysis.

Results Mean disease duration in the Parkinson group was 4. In general, Parkinson patients were slower than healthy control participants. A rest-tremor was detected in the three patients who were clinically assessed as having rest-tremor. Conclusions This study shows that standardized handwriting can provide objective measures for bradykinesia, tremor and micrographia to distinguish Parkinson patients from healthy control participants.

Introduction Parkinson's disease PD is a neurodegenerative disorder which generally results in several motor symptoms. The cardinal signs of the disease are bradykinesia slowness of movementrest tremor, rigidity muscular stiffness throughout the range of passive movement in a limb segment and postural and gait impairment [1].

Not all PD patients present these classical symptoms and several other motor symptoms can be observed, such as freezing, shuffling gate, hypomimia and micrographia small handwriting [2].

Clinical examination can be expressed in rating scales, e. The UPDRS is the most widely used and tested scale and consists of an impairment and disability section.

However, rating scales highly depend on the experience and interpretation of the physician performing the assessment and have limited precision for quantifying upper limb motor skill.Handwriting Analysis Questions Welcome to the web's best, free on-line handwriting analysis self-test.

The letters are like guardsmen on parade. The forward movement of the pen looks as though it has been carefully restrained. The writing does not flow, and there is no sloppiness or freedom of movement in the writing.
