A METHOD OF USING A VIRTUAL DIGITAL MODEL OF A PATIENT'S WALKING FOR THE DIFFERENTIATED CONSTRUCTION OF AN INDIVIDUAL PROGRAM OF PHYSICAL REHABILITATION IN THE EARLY RECOVERY PERIOD OF ISCHEMIC STROKE, DEPENDING ON THE AFFECTED REGION Russian patent published in 2021 - IPC A61B5/11 G06N3/00 

FIELD: medicine/neurology.

SUBSTANCE: invention relates to kinesiology, neurophysiology, medical rehabilitation, functional diagnostics, and can be used on outpatient basis, rehabilitation centers for diagnostics, differential diagnostics, methods of studying motor dysfunctions in acute cerebrovascular accident (ACVI), choice of rehabilitation methods and control of its effectiveness in patients with manifestations and consequences of strokes. To build an individual program of physical rehabilitation (IPFR), including the selection of physical exercises, specific kinematic parameters of walking should be considered, determined depending on area affected by ischemic stroke (IS) according to virtual digital model of patient's gait (VDMG) obtained during 3D video analysis of movements using high-resolution digital optoelectronic system SMART-D, equipped with high-resolution cameras with motion scanning frequency of up to 100 Hz per second, followed by animation and graphic construction of virtual motion model. The defining kinematic parameters of the motor pattern for VDMG in IS in the vertebrobasilar system (VBS) should follow correction-requiring signs: forward tilt of pelvis in sagittal plane during phase of support and transfer, with corresponding displacement of center of mass, with magnitude of angle of displacement of the pelvis anteriorly - more than 10° from average standard indicator of 7°, in absence of deviations of pelvis from standard indicators in frontal plane; on paretic and healthy side - increased flexion in hip joint (HJ) in transfer phase with insufficient extension in support phase, by more than 10° compared to upper limit of normative indicator given in table 1 in description, and insufficient plantar flexion of paretic and healthy side during the support-transfer period. As correction-requiring signs, following kinematic parameters of motor pattern of VDMG are taken in IS in the middle cerebral artery (MCA): displacement of pelvis in frontal plane with elevation of pelvis on paresis side by more than 1.5° compared to the norm in transfer phase with corresponding reciprocal lowering of pelvis on healthy side, in absence of pathological displacement of center of mass in sagittal plane; excessive internal rotation in hip joint in horizontal plane on both sides during entire step cycle compared to normative indicator, with impaired flexion and extension functions, with predominantly pronounced dysfunction of hip extensor muscles on paresis side, and insufficient plantar flexion on paretic and healthy side during support-transfer period.

EFFECT: method provides shorter physical rehabilitation times by increasing its personalization and quality characteristics, targeting elimination of neurological deficit, depending on affected area; targeted training provides more complete and high-quality restoration of motor functions.
