Introduction. The diagnostics of motor functions state plays an important role both as a result of the central nervous system impairments (stroke etc.) and as a result of injuries, traumas etc. As mobile devices expand the possibilities of modern medicine, the actual task is the synthesis of an effective mobile system for the motor functions state diagnosing at various stages of rehabilitation.The purpose of the paper is to develop a mobile system for personalized motor functions diagnostics for recovery of motor functions and speech motility, which functional capabilities contribute to the rehabilitation effectiveness increasing and usability both in clinical and home conditions, as well as in the fields conditions.Results. The motor and speech functions recovery in patients both after affection of the central and peripheral nervous system, as well as after injuries and traumas, in particular not only in clinical, but also in home and field conditions, makes requirements for personalization, mobility, ease of perception and usability of information given to the user.According to the requirements, the interface of mobile system for the motor function diagnostics was developed: set of user tasks was defined, scenario was developed for the patient to test own motor functions within the mobile system. The relation database's infologic model has been developed for the storage and accumulation of patients' motor functions data and following analysis by a physician.The algorithm for personalized motor functions diagnosing has been developed. It is based on expanded range of evidence criteria without taking into account by known analogues. The algorithm is implemented in the MovementTestStroke 1.2 mobile system with taking into account the interface and relation database. Such a system provides objectification of assessment, reduction of the probability of a physician's error and urgency in diagnostic and treatment decision-making, provides necessary and sufficient information to the user in a convenient digital and graphical forms, simplifies for the physician the motor functions state analyzing and the personalized treatment strategy creating.Conclusions. The mobile system MovementTestStroke 1.2 for motor function diagnostics can be used in clinical and home conditions to assess the motor functions state affected by central nervous system pathologies. With some system's modification based on additional research it can be used to assess the state of motor functions affected also by injuries and traumas. This creates the basis for personalized, mobile, urgent diagnostic and treatment decision-making by the physician.
