STUDY OF CLINICAL CHARACTERISTICS AND THE QUALITY OF LIFE OF PATIENTS WITH ESSENTIAL TREMOR

Abstract

Essential tremor (ET) is characterized by heterogeneity and variable intensity of hand tremor, which accounts for the severity of functional disorders, thus lowering the quality of life (QoL) of patients. The purpose of the study was to examine the clinical characteristics and quality of life indicators for various types dominant hand tremor of patients with ET. Findings: As a result of the research, we have identified subgroups of essential tremor characterized by significant variability of the hands tremor. The first subgroup has kinetic tremor prevailing over postural tremor, predominantly asymmetric; the second subgroup is represented by high-amplitude symmetric posture-kinetic tremor; the third group has low-amplitude posture-kinetic tremor. Patients with ET are defined by medium and low estimate of physical and mental components of the QoL. The patients of subgroups 1 and 2 were estimated the QoL lowest, whereas the health physical component was higher in patients of group 3 which was complemented by less functional disabilities.
