Application of filtering strategies to Multiple Sclerosis tremor: analysis of results

Abstract

Intention tremor severely compromises everyday life tasks in patients suffering from Multiple Sclerosis or Parkinson's disease. We report the result of our investigation on the properties of Multiple Sclerosis tremor. We analysed the case of handwriting and the effects of filtering tremor with proper numerical systems. An index for the evaluation of movements has been proposed, its properties have been verified with healthy users and used for evaluating efficiency of filtering on Multiple Sclerosis patients. The achieved results have been applied in the development of some technological aids for assisting therapist and patients in their work/life.
