The nomenclature of persons body parts (PBP) is considered from positions of possible directions of their movements research (MR). In article is shown the role of bone and muscular system, nervous system in ensuring PBP movements. Authors have been considered the parameters (characteristics) structure of various PBP movements including their volumes; performance dynamic characteristics; manifestation of muscular fatigue in the course of exercises; coordination of PBP movements; accuracy of movements management etc. In article have been analyzed main objectives of PBP MR. The set of variants for MR classification is offered. Authors proved application efficiency for MR of various movements types: free (natural); regulated (demonstrated) by the person which is carrying out research and/or computer program; movements, in the presence of resistance from external objects; movements which are carried out В«forciblyВ» - under action of compelling external forces. Merits and demerits for different classes of methods are compared in detail, specified technical and software means for their realization. For В«contactВ» methods of MR are considered functionality of autonomous goniometers; devices for assessment of linear movements; В«measuringВ» exoskeletons and their fragments; measuring blocks of the robotized complexes, including mechanotherapeutic. For contactless methods are analyzed merits and demerits of visual supervision of movements, including against measuring scales; methods of computer analysis (in on- and offline modes) with recognition of PBP images and their movements - on the basis of special В«markersВ» usage and without them; use of sensors, located out of persons body surface and reacting at PBP movements by changes of magnetic field, electric capacity and so forth; accelerometric approaches to MR, including usage of sensors for linear and angular accelerations; the combined methods. In article have been analyzed influence of information technologies development on functionality of various MR, efficiency and accuracy of receiving results; possibilities of data accumulation, their retrospective analysis. Separately are considered purposes and methods for tremor of PBP research - in a free state and in the presence of adjustable loadings.
