METHOD FOR REHABILITATION OF UPPER LIMBS OF STROKE PATIENTS, USING BIOLOGICAL FEEDBACK AND VIRTUAL REALITY ELEMENTS Russian patent published in 2023 - IPC A61N1/18 A61B5/11 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to a method for rehabilitation of upper limbs of stroke patients, using biological feedback and virtual reality elements. When implementing the method, a patient is provided with equipment for content reproduction with virtual reality elements and a motion capture system with sensors. A software package containing content formation elements with virtual reality elements and control elements is loaded. Then, in parallel with the reproduced content with virtual reality elements, the patient performs movements of the damaged part of the body, while registering an amplitude of movements and duration of their execution and organizing biological feedback. In this case, the patient is additionally provided with a system of electrodes. A software package is used, containing a regulatory route for performing movements described in a database of rehabilitation protocols and functionally combining the system of electrodes, equipment for content reproduction with virtual reality elements, the motion capture system, and an electronic computer for control of them, as well as input and processing of information. At the same time, a doctor inputs information about a recommended volume of movements into the electronic computer. Then, the patient is provided with equipment for content reproduction with virtual reality elements, the motion capture system with sensors, and the system of electrodes. The motion capture system is calibrated, during which, using a marker, a position of a lower starting point of the movement of the damaged upper limb is recorded, which is also the origin of coordinates in the motion capture system. The doctor selects a rehabilitation protocol from the database, and, during rehabilitation procedures, the patient, in parallel with the reproduced content with virtual reality elements, performs movements of the damaged upper limb according to the rehabilitation protocol, when the motion capture system registers, in real time, an amplitude of movements in large joints, % of angular deviation relatively to the lower starting point of movement of the damaged upper limb, and duration of movements. At the same time, biological feedback is organized starting from the second rehabilitation procedure, when, in case of deviation of the movement of the damaged upper limb from the regulatory route of movement, multi-channel asynchronous local percutaneous muscle electrical stimulation is performed by means of the system of electrodes, so that an actual route of movement of the damaged upper limb corresponds to the route of movement, established by the doctor, in the form of a regulatory route adjusted taking into account the recommended volume of movements.

EFFECT: efficiency of rehabilitation procedures is increased due to organization of automatic, stable, and objective biological feedback, which does not fully control patient’s motor activity, but only corrects a volume and nature of movements, use of a software package, which allows a doctor to independently configure a complex and order of rehabilitation procedures, including personalized adjustment, as well as making changes in the course of rehabilitation procedures and rehabilitation protocols.
