“…Since the mid-20th century, human movement analysis has been part of clinical practice [ 24 ]. The first studies on gait using quantitative outcome measures were conducted in the 1960s, taking temporal–spatial parameters, the kinematics of limb movement in three planes, and kinetics into account [ 25 ]. The images captured through a lens can be submitted to a series of aberrations or distortions, which influence the measurements.…”

The study of the foot is relevant in kinematic analyses of gait. Images captured through a lens can be subjected to various aberrations or distortions that affect the measurements. An in vitro study was performed with a rearfoot simulator to compare the apparent degrees (photographed) with the real ones (placed in the simulator) in the plane of the rearfoot’s orientation, according to variations in the capture angle in other planes of space (the sagittal plane and transverse plane—the latter determined by the foot progression angle). The following regression formula was calculated to correct the distortion of the image: real frontal plane = 0.045 + (1.014 × apparent frontal plane) − (0.018 × sagittal plane × foot progression angle). Considering the results of this study, and already knowing its angle in the transverse and sagittal planes, it is possible to determine the angle of a simulated calcaneus with respect to the ground in the frontal plane, in spite of distortions caused by perspective and the lack of perpendicularity, by applying the above regression formula. The results show that the angular measurements of a body segment made on frames can produce erroneous data due to the variation in the perspective from which the image is taken. This distortion must be considered when determining the real values of the measurements.

“…При анализе литературных источников [1,3,7,8,[13][14][15][16][17][18][19] мы не обнаружили исследований с интегральным анализом патологической биомеханики, ввиду чего нами была разработана собственная диагностическая методика постурального тестирования. В рамках предложенной концепции выполнялась стандартизированная оценка МН по отдельным фазам типичных отклонений тела: латеральных наклонов вокруг сагиттальной оси (тест 1), вентральных и дорсальных наклонов вокруг фронтальной оси (тест 2), перемещений вдоль (тест 3) и вокруг (тест 4) вертикальной оси с последующим кинематическим анализом виртуальной скелетной модели, реконструированной из инерциальных датчиков.…”

оценка инфаркта головного мозга, как правило, базируется на применении наиболее адаптированных классификаций TOAST и ASCOD. При этом их общий недостаток связан с их этиопатогенетической ориентацией, что резко ограничивает клиническую ценность данных классификаций для последующей медицинской реабилитации. В то же время международная классификация функционирования, ограничения жизнедеятельности и здоровья, с одной стороны, более применима в восстановительной медицине, а с другой -достаточно сложна в описании комплексной проблемы моторных нарушений при инфаркте головного мозга. Целью исследования являлась разработка классификации моторных нарушений при инфаркте головного мозга.

“…The relationship between neuronal connectivity and gait function after stroke remains unclear. Gait function is one of most complex motor skills in humans, and the control of gait relies on multiple brain areas, including the cerebral cortex, brainstem, cerebellum, and basal ganglia [3]. Previous studies using neuroimaging have attempted to describe the relationship between the location of the stroke lesion and gait dysfunction [4][5][6][7].…”

Gait dysfunction is a leading cause of long-term disability after stroke. The mechanisms underlying recovery of gait function are unknown. We retrospectively evaluated the association between structural connectivity and gait function in 127 patients with unilateral supratentorial stroke (>1 month after stroke). All patients underwent T1-weighted, diffusion tensor imaging and functional ambulation categorization. Voxel-wise linear regression analyses of the images were conducted using fractional anisotropy, mean diffusivity, and mode of anisotropy mapping as dependent variables, while the functional ambulation category was used as an independent variable with age and days after stroke as covariates. The functional ambulation category was positively associated with increased fractional anisotropy in the lesioned cortico-ponto-cerebellar system, corona radiata of the non-lesioned corticospinal tract pathway, bilateral medial lemniscus in the brainstem, and the corpus callosum. The functional ambulation category was also positively associated with increased mode of anisotropy in the lesioned posterior corpus callosum. In conclusion, structural connectivity associated with motor coordination and feedback affects gait function after stroke. Diffusion tensor imaging for evaluating structural connectivity can help to predict gait recovery and target rehabilitation goals after stroke.
