“…For a given patient, some movement patterns are affected more severely by the disease than others, and Jobbágy et al (1998) have recommended personalisation of tests. As for the finger-tapping test, the score of one or more fingers can be more informative than the score of a hand.…”

In this study, a device based on patient motion capture is developed for the reliable and non-invasive diagnosis of neurodegenerative diseases. The primary objective of this study is the classification of differential diagnosis between Parkinson's disease (PD) and essential tremor (ET). The DIMETER system has been used in the diagnoses of a significant number of patients at two medical centers in Spain. Research studies on classification have primarily focused on the use of well-known and reliable diagnosis criteria developed by qualified personnel. Here, we first present a literature review of the methods used to detect and evaluate tremor; then, we describe the DIMETER device in terms of the software and hardware used and the battery of tests developed to obtain the best diagnoses. All of the tests are classified and described in terms of the characteristics of the data obtained. A list of parameters obtained from the tests is provided, and the results obtained using multilayer perceptron (MLP) neural networks are presented and analyzed.

“…The authors concluded that the computer-assisted analysis of automated handwritings could be used as a fast objective method for quantifying dopamimetic effect on the kinematics of handwriting. Jobbagy et al (1998) described a measurement technique based on the Precision Motion Analyzer (PRIMAS) that can be used to diagnose PD. PRIMAS was suggested as a screening test to objectively measure the progress of the disease and/or the efficacy of the therapy.…”

“…Various methods of measuring the classical symptoms of PD in an objective and quantitative way have been proposed (Ghika et al 1993;Jobbagy et al 1998), specifically for tapping test (Ziv et al 1999;Yahalom et al 2004), the quantification of rigidity (Patrick et al 2001), handwriting (Eichhorn et al 1996), to evaluate FOG (Han et al 2003;Moore et al 2008), or to assess MBs in hand movements (Popovic et al 2002). Ghika et al (1993) designed portable system based upon a PC to measure tremor, bradikinezia, and muscle tone.…”

The non-volitional sudden discontinuation of motor activity, called motor block (MB) or freezing is most commonly associated with Parkinson's disease (PD). MB extends beyond the classical manifestations of PD: akinezia, bradykinezia, rigidity, tremor, and postural instability. MB has been observed and quantified in internally cued repetitive movements such as gait, speech, handwriting, and manual tapping tasks as a distinct feature of PD. We present a simple measurement system for objective evaluation of MB during point-to-point hand movements in patients with PD. Hand trajectories were evaluated in eight PD patients based on values obtained from a digitizing tablet (DT) score. 50 trials per day were recorded in seven consecutive working days. Subjects were instructed to consciously prepare and self-initiate movements between arbitrarily fixed starting and target points without lifting a wireless magnetic mouse. MB was identified as the time interval during movement with no change in coordinates. We analyzed three kinematic parameters: duration, start and number of MBs. If MBs were documented, the DT score was 1, if not, 0. Results were then compared with the ratings of the question in motor section related to freezing of hands from the Unified Parkinson's Disease Rating Scale (UPDRS). For all patients, DT score was in agreement with the UPDRS. Present results indicate that DT is useful for assessing MBs during volitional planar hand movement. This low-cost instrument may be included in a clinical test battery because of short testing time and troublefree preparation of patient.Parkinson's disease; motor block; freezing; digitizing tablet; assessment.Tohoku
