Wise Spiralography

よく知られた実績のある方法で神経障害を自分でテストする

With this application you will be able to see, how your mind and motoric abilities are affected by possibility of neurological disorders like Parkinson's disease or other neurological discfunctions.

As you might know, large procent of all the elderly people are (or will be) affected by neurological disorders of various types. This application will help you to decide if proper medical examination is needed for you.

Tremor and moving disorders are one of the main and relativly difficult symptoms for a pacient nevrodegenerative illness. While the clinical analysis of the pacient is performed it is vital to identify the type of tremor to set the right diagnosis.

For exact measurement of tremor – its frequencys and amplitudes, the method of spiralography using the tablets or smart phones is most useful. The use of digital tablets for tremor identification enables more accurate tremor data in comparison with old methods of drawing evaluation. Those methods usually determine only subjective classification of tremor to normal, gentle, intermediate and strong, while the use of digital tablets accuretly quantifies the tremor.

How does it function?

During measurement the pacient sits on the chair and is drawing a spiral on programated grafical tablet with tablet's pen – freehanded and on generated template. With computer analysis with given criteria we get data nedeed to determine tremor type on the basis of joint characteristic, typical for certain clinical group.

During the draw process the pacient is required to keep the pen on tablet surface for the whole time of drawing. It frequently occurs that for pacients with severe tremor this condition is not met, but newer digital tablets track the pen position even if it is raised from the surface for a few centimeters. This makes the measurments on people with strong tremor easier and without the need for costum adjustments.

Because each tremor has unique oscillation, it is easy to use spectral analysis, which is the most common method of tremor quantification.

The data we acquired with the help of digital tablets are organized trought 11 criteria.

That makes possible to watch the data about the tremor from more different prespectives. The results are: the drawing of the actual spiral, time versus trace of spiral, radius/angle transform, absolut, radial and tangecial speed in response to time, tremor spectra, direction of the tremor, pen pressure versus time, pressure cone and pressure spectra.

The results can be assesed and on the basis of the properties of individual clinical group we can identify the present tremor. Indications for use: esencial tremor, parkinsonian, cerebral, psihogenic tremor.

Parkinson's disease does not directly cause people to die, but the condition can place great strain on the body, and can make some people more vulnerable to serious and life-threatening infections.
