Abstract
A tremor an involuntary rhythmic oscillatory movement of a part of the body-belongs to one of the most disabling features of multiple sclerosis (MS). In clinical practice, the tremor is currently classified according to clinical scales.
Unfortunately, this approach is fully subjective in principle, and the objective classification is still missing. As is shown in the literature, the tremor can be investigated by accelerometers and gyroscopes based on the frequency analysis and other advanced methods of signal processing.
A condition of the successful development of these methods is an existence of a signal database of healthy subjects. This paper concerns with the collecting of the signal database of healthy control subjects.
The signals were acquired on the group of healthy subjects aged from 18 to 50 years (20 subjects). For each patient, one-minute records of postural tremor (for both right and left hand, with and without closed eyes; 4 records together) have been acquired, and also several clinical tests have been passed (a measurement of a strength by a handgrip, a pinch key, and a trippod test, a nine-hole peg test, a coin rotation task test, and a tip pinch test).
All records have been supplemented by anamnestic data.
