“…Подход к определению «нормального» значения передаточной функции (связанного с чувствительностью, глубиной обратной связи) в данном наблюдении, по нашему мнению, может быть распространен на любые Отдельно следует отметить, что изменение функции управления по визуальной обратной связи в предложенной модели у пациентов с диабетической невропатией принципиально не отличалось от динамики результатов, полученных нами в сходном наблюдении у здоровых добровольцев [11], что может указывать на наличие универсальных закономерностей, сохраняющих свое значение даже при сниженных возможностях испытуемых.…”

“…С учетом этих и других известных нам сведений проводилось наблюдение за пациентами с диабетической нейропатией, предполагая, что в сенсорной организации вертикальной позы у них есть специфические особенности, обусловленные болезнью. Ранее на здоровых молодых добровольцах [11] было установлено, что изменение передаточной функции («чувствительности») в задаче с визуальной обратной связью является ключевым фактором, влияющим на результат выполнения, связанный с удержанием максимально стабильной вертикальной позы и слежением за визуальной целью. Однако возможные различия влияний изменения глубины обратной связи в задаче с визуальной обратной связью у здоровых добровольцев и пациентов с возможными изменениями вследствие периферической нейропатии остаются малоисследованными.…”

“…Использование стандартизованного измерительного оборудования (с установленными метрологическими характеристиками) и описанных методов расчета применявшихся показателей позволяет получить сходные данные, соответствующие состоянию участников наблюдения [11]. В этой связи основным условием для воспроизведения наблюдения является использование измерителя (силовая платформа) с подтвержденными метрологическими свойствами.…”

BACKGRAUND: Violation of gait and body balance in patients with diabetic polyneuropathy actualizes the development of new effective measures of motor rehabilitation. In this regard, an observation was carried out in which biofeedback training was used for the reference reaction in the conditions of variable feedback parameters.AIMS: To investigate the effect of a stepwise change in the depth of feedback (sensitivity) in a motor-cognitive task with visual feedback on the reference response to the result of its execution.METHODS: Single-sample observational observation with controlled conditions. 27 patients with diabetic polyneuropathy. All patients were treated according to modern standards. The observation was performed in one series at the beginning of the course of inpatient treatment. Estimation of body balance on a power platform — stabiloplatform) — stabilometry. The procedure included 5 stages of management, in which the patient followed the instructions (training) in which there was a stepwise increase in the depth of feedback («sensitivity») at each stage from 10 to 50% of the conditional «normal», with a step of 10%. A quantitative assessment of the external result (execution of instructions) and parameters of regulation of the vertical posture was carried out.RESULTS: All patients included in the follow-up showed that the implementation of instructions with increasing depth of feedback decreased sharply when the conditionally «normal» value was exceeded by 30–35%. At the same time, the initial parameters of vertical posture control in the sample patients did not affect the dynamics of results when performing the task with visual feedback. Factor analysis indicates the presence of the only significant factor associated with the effectiveness of performing a motor-cognitive task here — changes in the depth of feedback. The accepted significance level α = 0.05.CONCLUSIONS: The depth of feedback in motor-cognitive tasks with visual feedback is a key characteristic that affects performance. The ability to increase the depth of feedback in the range of about 35; from conditionally «normal», can be useful for ensuring differentiation of loads during motor rehabilitation of patients in order to increase the effectiveness of training. In addition, in theoretical terms, the proposed model of the motor-cognitive problem can be relevant in the study of «dual» problems, where the relationship of motor and cognitive components is studied.

Objective. The study deals the influence of different biofeedback (BFB) depth for support reaction on the performance of a short course (3 sessions) for a motor-cognitive training of static and dynamic types in the rehabilitation of patients after a radical mastectomy. Subjects and methods. 21 patients between the ages of 40 and 74 years after radical mastectomy for breast cancer (BC) were examined and performed rehabilitation with the BFB depth for support reaction with a change normal sensitiveness of the force platform by 15, 30, 45 and 60 %. The 1st group included aged 40–54 patients, and the 2nd group included aged 57–74 patients. Results and conclusion. It was found that after 3 courses of the motor-cognitive training of dynamic type (“Lights”), conditionally “younger” patients showed an increase of their results from the fi rst to the third session in all four variants of the changing BFB depth (15, 30, 45, 60 %) from the normal sensitiveness of the force platform. These results weren’t found in dynamics in the 2nd group of patients. Data from static training (“Target”) shows that changing of the BFB depth in the range from 15 to 60 % don’t affect the results of exercises in both groups throughout 3 sessions. These types of training for older patients weren’t as effective as for younger patients over such a short period. Probably, these results of dynamic training depend on multitasking and learning difficulties. The obtained results should be taken into account when a training plan will be drowned up because the incorrect selection of the BFB depth and the short period of medical rehabilitation will reduce the eff ect of training.
