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.

Background: The aim of the study is to assess the body balance and podological parameters and body composition of young footballers in the context of the control of football training. Methods: The study examined the distribution of the pressure of the part of the foot on the ground, the arch of the foot, and the analysis of the body composition of the boys. The pressure center for both feet and the whole body was also examined. The study involved 90 youth footballers from Olsztyn and Barczewo in three age groups: 8–10 years, 11–13 years old, and 14–16 years. The study used the Inbody 270 body composition analyzer and the EPSR1, a mat that measures the pressure distribution of the feet on the ground. Results: The results showed statistically significant differences in almost every case for each area of the foot between the groups of the examined boys. The most significant differences were observed for the metatarsal area and the left heel. In the case of stabilization of the whole body, statistically significant differences were noted between all study groups. In the case of the body composition parameters, in the examined boys, a coherent direction of changes was noticed for most of them. The relationships and correlations between the examined parameters were also investigated. The significance level in the study was set at p < 0.05. Conclusions: Under the training rigor, a statistically significant increase in stability was observed with age. The total length of the longitudinal arch of both feet of the examined boys showed a tendency to flatten in direct proportion to the age of the examined boys. Mean values of the body composition parameters reflect changes with the ontogenetic development, basic somatic parameters (body height and weight) and training experience, and thus with the intensity and volume of training. This indicates a correct training process that does not interfere with the proper development of the body in terms of tissue and biochemical composition.

Objectives: This study investigated cognitive-motor interference on the relationship of speed and accuracy during a cognitive and upper-limb motor dual task. Method: Nine stroke patients (56.5±7.3 years; M:9) participated in a series of cognitive-motor dual tasks. A subject with chronic stroke was seated with paretic hand fastened on the handle and then one of five motor tasks was provided (Figure 1A). Visual feedback in a front screen was synchronized as the handle cursor moves within the movement trajectory with two difficulty levels (5cm or 10cm). In a dual task, a cognitive task, Serial Seven(S7), was concurrently provided with a randomly chosen number at the onset of the motor task by a test administrator.Figure 1 Cognitive-Motor dual task setup (left up) and trajectory shapes (Diagonoal; Mediolateral; Anteroposterior; Cross; Circle) and level of difficulties (Easy 10cm or Hard 5cm) in motor tasks. The motor speed and accuracy and the cognitive speed and accuracy were evaluated during one-minute trial time. Pearson-correlation coefficients evaluated outcome relationship of the speed and accuracy in single or cognitive-motor dual tasks with the significance level 0.05 using a commercial statistics package (SPSS ver 22, Chicago IL,US). Results: There were significant positive correlation between single and dual motor speeds ( Easy :R 2 =0.678,p<0.001; Hard : R 2 =0.714,p<0.001) and significant negative correlationbetween single motor speed and dual cognitive speed ( Easy : R 2 =0.661,p<0.001; Hard :R 2 =0.6523,p<0.001) (Figure 1B) Conclusions: There were significant correlations between the upper-limb horizontal movements with visual feedback and S7 cognitive task. This study may provide useful information on upper-limb motor robotic therapies using 2D horizontal upper-limb movements.

Observation is recommended in motor rehabilitation. For this reason, the aim of this study was to experimentally test the feasibility and benefit of including mirror feedback in vision-based rehabilitation systems: we projected the user on the screen. We conducted a user study by using a previously evaluated system that improved the balance and postural control of adults with cerebral palsy. We used a within-subjects design with the two defined feedback conditions (mirrorandno-mirror) with two different groups of users (8with disabilitiesand 32without disabilities) using usability measures (time-to-start(Ts) andtime-to-complete(Tc)). A two-tailed paired samplest-test confirmed that in case of disabilities the mirror feedback facilitated the interaction in vision-based systems for rehabilitation. The measured times were significantly worse in the absence of the user’s own visual feedback (Ts=7.09(P<0.001) andTc=4.48(P<0.005)). In vision-based interaction systems, the input device is the user’s own body; therefore, it makes sense that feedback should be related to the body of the user. In case of disabilities the mirror feedback mechanisms facilitated the interaction in vision-based systems for rehabilitation. Results recommends developers and researchers use this improvement in vision-based motor rehabilitation interactive systems.

Dislocation Of The Hip

The article presents the results of rehabilitation in children with sequelae of spina bifida using the robotic complex “Pediatric Lokomat” produced by «Hocoma» company (Switzerland). In such patients, one of the most significant orthopedic problems in frequency and clinical relevance is the instability of the hip joint. The approach to rehabilitation treatment in children after reconstructive surgery of the hip involves the principle “early motion - late weight bearing”. Conventional methods of rehabilitation treatment are performed in supine position, and don’t allow to combine this principle with training the skills of vertical posture, which leads to the development of osteoporosis and the risk of pathological fractures. Robotic mechanotherapy enables to cope with this problem by working in isokinetic mode with no load on the supporting surface.

The aim of this study was the effect of Bio/Neurofeedback training on performance, audio and visual attention of elite shooters. In this study 36 elite shooters of Kermanshah Province participated. They divided in three groups. Two groups were experimental groups how participated biofeedback and neurofeedback training and one group was control group. All participants were tried that their trainings as well as the number of shoots were closely controlled in order to assure their physical and special trainings. In this study, for attention affects the computerized Integrated Visual and Auditory test (IVA) was used. This test has been considered as both a pretest and a posttest after the therapeutic intervention in three groups. The score of shooting also were collected before and after intervention. Each athlete in neurofeedback training group carried out the neurofeedback training for 20 sessions, each lasting 45 minutes. To do so, both auricles and T3 and PZ of each individual were cleaned using alcohol and new-perp gel to prepare for the neurofeedback training. The biofeedback training was heart rate and respiratory training.  To compare the results of the pretest and the posttest in each group, the dependent t-test was used. For compare three groups we used ANOVA test. The significance level was set at 0.05. The results indicated that there is a significant difference in three groups. It indicates a significant increase in the total score for attention after the implementation of the biofeedback and neurofeedback training. The results showed that the attention mean scores in three visual, audio, and total variables were higher in the posttest than in the pretest for two experimental groups. The results also indicated that the scores of the shoots were improved after training.  According the research finding, we can be said that the neurofeedback and biofeedback  training act on the waves of the sensory-motor beats and which are responsible for coordinating the sensory-motor acts of the brain waves and physiology parameters (Heart and respiratory systems), and strengthen these waves in addition to the beta ones and rate of the heart and respiration. This leads to regulating the performance and attention.

Different properties of displays, features of visual perception of three-dimensional images and other conditions, probably affect the effectiveness of motor rehabilitation when using a visual feedback channel and virtual reality technology. A brief review presents the latest publications on a choice of 2D or 3D displays. It is concluded that the presence of many features not only creates difficulties in comparing the effects of using various equipment, but also provides the potential for targeted display selection for a particular rehabilitation task.

The dearth of empirical research in the application of biofeedback is discussed. Exp. 1 assessed relationships among biofeedback EMG training, EMG levels, cognitive task performance, and task difficulty. 72 subjects (male or female college students) were administered 1 trial on an iconic memory task with either EMG audio feedback, sham EMG audio feedback, or no feedback. Three levels of task difficulty were used. One 20-min. training session significantly lowered EMG responses, and task performance was inversely related to task difficulty. No relationship between EMG level and task performance was observed. Exp. 2 investigated the effect of increased EMG responses on cognitive task performance for one level of difficulty. One biofeedback training session did not significantly increase frontalis EMG, and there was no relationship between increased EMG and task performance.
