While neurologists address the most debilitating and severe movement disorders, they may be interested in documenting the speed, fluency, and precision of pen movements during each patient's examination so that they can monitor the effectiveness of treatment and the progress of disease.

By measuring and quantifying minute differences between successive measurements, neurologists will be able to measure much quicker short-term changes within patients and relevant differences between patients than would be possible with the visual inspection alone. The system allows also to measure the tremor frequency at rest and the action tremor.

Medical professionals and researchers focusing in movement disorders, can use the MovAlyzeR system to measure and analyze movement disorders such as Parkinsonism.

Application Areas

• Neurology
• Gerontology
• Rehabilitation
• Physiotherapy

Examples

• Charting short-term effects of medication
• Charting long-term effects of aging

Mental conditions and the extrapyramidal side effects due to psychotic drugs may affect a patient's ability to efficiently produce movements of different sizes and sequences of movements. By measuring relationships between size, speed, and inter-movement pauses, it will be possible to quantitatively express the severity of a condition or a side effect.
