This chapter deals with cable-driven robots when applied in physical rehabilitation. In general, neurorehabilitation is limited to physical therapy that is delivered by clinicians and potentially augmented by robotic tools to facilitate neurorehabilitation and to reduce the consequences of central nervous system injury. Among the robotic tools for rehabilitation can be considered the cable-driven manipulators. First, this chapter presents the upper and lower human limbs movements. The main rehabilitation robots are presented as exoskeletons and cable-driven manipulators. After, the cable-driven manipulators theory is introduced focusing on considerations for robot design in rehabilitation and control with safe human-machine interaction. Experimental examples with different cable-driven robot's structures are presented so that this chapter suggests that these structures can be used as a complement to conventional therapies and not as a substitute. Finally, this chapter presents the clinical evidence in cable-driven robots when applied in physical rehabilitation.

Eight special considerations are reported for use with the Quick Test (Ammons & Ammons, 1962) when testing mentally retarded or central nervous system-impaired subjects. Use of these techniques may result in a more accurate IQ. The techniques pertain to the manner of presenting stimuli, examiner's empathy, subject's self-perception, and control of guessing. The techniques are intended to supplement directions that appear in the Quick Test manual.

Epigenetic modifications are considered of utmost significance for tumor ontogenesis and progression. Especially, it has been found that miRNA expression, as well as DNA methylation plays a significant role in central nervous system tumors during childhood. A total of 49 resected brain tumors from children were used for further analysis. DNA methylation was identified with methylation-specific MLPA and, in particular, for the tumor suppressor genes CASP8, RASSF1, MGMT, MSH6, GATA5, ATM1, TP53, and CADM1. miRNAs were identified with microarray screening, as well as selected samples, were tested for their mRNA expression levels. CASP8, RASSF1 were the most frequently methylated genes in all tumor samples. Simultaneous methylation of genes manifested significant results with respect to tumor staging, tumor type, and the differentiation of tumor and control samples. There was no significant dependence observed with the methylation of one gene promoter, rather with the simultaneous presence of all detected methylated genes’ promoters. miRNA expression was found to be correlated to gene methylation. Epigenetic regulation appears to be of major importance in tumor progression and pathophysiology, making it an imperative field of study.

The objective: to present information about potential mechanisms of development of sepsis-associated encephalopathy, and its potential role in sepsis outcome.Neurohumoral regulation is the most important system that integrates many functions of variable values to achieve the final result that is beneficial for the host. The central nervous system (CNS) is the switch and control mechanism responsible for the functioning of this system. The increasing number of studies indicating the relationship between the development of sepsis and occurrence of qualitative and quantitative changes in the central nervous system suggests that it is the degree of damage to neurohumoral regulation mechanisms at the very beginning of the disease can significantly determine the severity of the course and prognosis of the outcome of multiple organ failure syndrome in sepsis.

The subject of this publication is the medical rehabilitation of children with perinatal lesions of the central nervous system. Currently, the main methodological principles of stage-by-stage medical rehabilitation of newborns, mainly children with the consequencesof perinatal damage to the nervous system, have been determined. Special attention should be paid to the issue of minimal use of medicines in children with perinatal pathology, in this regard, an importanttask is the development and scientific justification of new non-drug technologies of medical rehabilitation, especially in childrenunder 1 year. Medical rehabilitation sets itself the following tasks: stimulation of blood circulation in the brain tissues, improvement of muscle toneby affecting the central nervous system and the peripheral nervous system, activation of neuromuscular transmission processes andimprovement of psychomotor development of a child with perinatal pathology of the central nervous system. Medical rehabilitationof children with perinatal lesions of the central nervous system begins at the earliest possible time and is carried out by specialists ofa multidisciplinary rehabilitation team based on an individual medical rehabilitation program. Aim. To study the results of research conducted by Russian and foreign authors on the issues of physical rehabilitation of children withperinatal damage to the central nervous system and to conduct an analysis of the effectiveness of the proposed technologies. Material and methods. The literature review for this article was conducted from the elibrary, PubMed, Cochrane Library databaseswith a search depth of 10 years. The selection of publications was carried out using keywords: non-drug technologies, perinatal damageto the central nervous system; perinatal hypoxic-ischemic encephalopathy, kinesotherapy, neurodevelopmental therapy, massage,thin finger training method, dry immersion, fitball gymnastics, V. Voit therapy; Bobat therapy. Conclusion. Currently, a wide range of non-drug technologies of medical rehabilitation of children with the consequences of perinataldamage to the central nervous system is used such as therapeutic gymnastics, massage, kinesiotherapy with a neuroreflex locomotionaccording to Vojta’s method, Bobath-therapy, massage, etc. The analysis of publications has shown that kinesotherapy and massagein in the complex of rehabilitation measures for children with perinatal lesions allows to increase the effectiveness of rehabilitationmeasures, reduce the severity of motor disorders, and can help reduce the frequency of formation of cerebral palsy.

The purpose of the study was to develop a mathematical mechanism which could describe laws of changing electrical signals in nerve fibers in man’s lower extremities and hip prosthesis movement. The article presents a schematic diagram of the bioelectric hip prosthesis control system, main elements of which are an actuator, a control device, and a primary data unit. There are given actual mathematical models of prostheses movement and control signals of man’s central nervous system; on their base was designed the mathematical model controlling bioelectric hip prosthesis movement. A specific feature of the model offered is that the model has a function to characterize a signal transfer from the central nervous system to the actuator of prosthesis. The research results can be applied in the course of hardware and software implementation of bioelectrical prostheses, taking into account physical abilities of the users, creating specific algorithms, studying electric and dynamic characteristics of these devices.

A set of studies has been focused on identifying “markers” in aircraft data that are indicative of human factors issues. In this paper we discuss an experiment that investigated if human error is predictable from the error observed from the combined human-machine system. Sixteen pilots flew simulated instrument approaches under varying levels of workload and control augmentation conditions. Operator control lag, gain, delay, and error extent were computed from aircraft lateral path errors. These parameters along with pupil diameter data were analyzed for differences across workload conditions. Main effects for workload were found with respect to all control parameters consistent with the experiment hypotheses, but the effects were very small. Operator delay in responding to errors appeared inversely correlated with workload. Statistically significant differences were also found with respect to error extent ad pupil diameter.
