There is a range of issues within transfer of a patient into the late period of re-habilitation which reduce the general efficiency of rehabilitation measures. First of all, it is a low availability, remoteness and limited throughput capability of rehabilitation centers and specialized sanitariums, except for large towns. So, rehabilitation within the late period is mainly fulfilled independently at home that decreases a quality of recovery exercise performance and result of such rehabilitation correspondingly. During performance of exercises for physical treatment independently, a parent should adequately estimate capabilities of your body and strictly fulfill the technique of the exercise performance. Most people do not know peculiarities of the exercise performance technology and motions are often performed not fully because of pain by decreasing the amplitude significantly.

Presence of these issues greatly determines low quality of the ambulatory rehabilitation and, as a consequence, dissatisfaction of the patient by obtained medical services. That’s why application of contemporary approaches to implementation of telemedical systems for remote rehabilitation of motor activity processes taking into account possibility to obtain information about quality of the exercise performance in real time according to specified criteria on the basis of application of available technical means of objective control is topical. Automation of the home rehabilitation process is possible by using smart re-cording systems and analysis of the motor activity based on a smartphone.

Purpose of the present paper is to create a mobile system to support the performance of rehabilitation exercises based on the registration and analysis of the parameters of the movement of the lower limb of a person using the built-in motion sensors of a smartphone attached to the ankle.

Within development of the project “NEFITNES”, our team has developed and successfully implemented several smartphone applications contained complexes of exercises recommended for pathologies of the knee joint and spine. The algorithm implemented in the developed software uses sensors of smartphone motions to control qualitative and quantitative characteristics of executed exercises. A concept of online physical rehabilitation with feedback in real time that allows controlling the direction and amplitude of a motion during execution of an exercise and to use a pulse as an indicator of the physical load level has been developed and patented as a part of authors’ work.

The use of a mobile system improves patients' commitment to physical rehabilitation and increases the effectiveness of outpatient treatment. At the moment, free access to mobile rehabilitation technologies is provided in the form of a mobile application “NEFITNES”. Prototype testing has been fulfilled on the basis of the State-Financed Institution “Clinical and Research Institute of Emergency Pediatric Surgery and Trauma” of Healthcare Department (CRIEPST) within the project “Digital rehabilitation”. Corresponding methodological recommendations how to execute exercises in hospitals and at home have been published.
