Theoretical and experimental research on the development of an analysis system of the hand tremor movement for patients with Parkinson’s disease

Theoretical studies indicate the existence of the tremor in the human body, normally physiological, barely visible, and which occurs when the upper limbs are stretch to the front or when very high precision is required in carrying out an activity. Different experimental researches seek the theoretical fundament of the tremor movements or, develop evaluating systems for this type of movement, and last but not least are creating systems for behavioural help for people who develop forms of tremor with effects on comfort. Thus, in the first part of the paper, the specific clinical tremor forms are analyzed, as well as the manifestation forms and the parameters quantifying methods of this movement form developed in the human body. In the second part of the work is reviewed the substantiation of the analysis models of tremor type oscillations. In the third part of this paper, the experimental setup developed is presented, focusing on finding the best behavioural help solution for patients with pathological tremors and presents some considerations related to the device constructive aspects. In the final part, the approach conclusions of developing an assistive system for patients with pathological tremors are presented, on the highlight of the parkinsonian tremor patients.
