Análise cinemática da marcha livre e adaptativa de pacientes com doença de Parkinson e idosos sadios: efeito da dica auditiva

Disorders in gait are identified in Parkinson’s disease patients. As a result, the capacity of walking independently and the interaction with the environment can be impairment. So, the auditory cues have been utilized as a non-pharmacological treatment to improve the locomotor impairment of the PD patients. However, these effects were observed in the regular lands and it’s not known the effects of auditory cues in gait during avoidance obstacles that could be more threaten for these patients. Yet, few studies in the literature compare the Parkinson’s disease patients with the older adults during the locomotor tasks and obstacle avoidance in association with the effects of auditory cues. The aim of the study is to compare the effects of the auditory cues in the gait and during obstacle avoidance in PD patients and older adults. 30 subjects distributed in two groups (Group 1 - 15, Parkinson’s disease patients; Group 2 - 15, healthy older adults) are going to participate of this study. After the participation approval, the assessment of clinical condition will be done by a physician. So, to investigate the locomotor pattern, it will be done a kinematic analysis. The experimental task is to walk on 8 m pathway and 18 trials will be done (6 for the free gait and 12 for adaptive gait). For the adaptive gait, two different obstacle heights will be manipulated: high obstacle (HO) and low obstacle (LO). In order to verify possible differences between the groups and the experimental condition, multivariance tests will be used with a significance level of 0.05. MANOVA revealed effect of condition and task. Thus, with DA, we observed an increase in cadence and reduced single support and stride length. When the tasks were compared, it was observed that the LO task, subjects had lower velocity and stride length... 9Complete abstract click electronic access below)

Análise preliminar para a estimativa da perda de calor sensível de um fluido homogêneo térmico em um reservatório de geometria cilindrica

This work analyzed the loss of sensible heat from one fluid to be considered homogeneous heat distribution on a thermal reservoir with cylindrical geometries composite insulating layers. We studied two thermal reservoirs with a volume of 20 liters, and the first has a layer thickness of 75 mm of expanding polyurethane foam wrapped in the polycarbonate container and the second container has only layer thickness of 5 mm of polycarbonate, as insulation of fluid of the external environment. The experimental results are compared with theoretical results obtained through a calculation script, displayed and detailed during the work development, from the theory of energy balance. The maximum error introduced between the theoretical and experimental results were 3.5% and 1.4% respectively for the Boilers with or without a polyurethane coating

Tarefas de triangulação com restrições perceptuais em pessoas com deficiência auditiva: um estudo por meio de gps

This study aimed to investigate how people with hearing disability perform tasks of distances estimation for locomotion and navigation when deprived of effective perceptual and proprioceptive information. For this, participants with hearing disability went three distances being the first and second 100 meters and the third 140 meters (triangulation) from a source point in an inverted L open field trajectory and then returned to the origin, and the first two were driven by a researcher guide with adapted GPS coordinates of the study, and the third being three free-form sessions, the first one without any perceptual and proprioceptive restriction, the second without visual perception, and the third on the wheel-chair, that is, without proprioception. The results showed that people with hearing disability without the knowledge of the path do not possess satisfactory accuracy but when they learn the way even with the restriction of visual perception and proprioception they can return to the starting point in a task of triangulation. The "t" students test with a significance level of 5% (2.131) indicates significant differences between the first task without any perceptual restriction and the third where they performed in the wheelchair. To achieve these results we used remote monitoring via GPS and the TrackMaker software.

Índice geométrico e perda de carga localizada em conexões de emissores "online"

The objective of this research is to present a study on a relationship between the local head loss in connection of emitters in pipes with different diameters used in drip irrigation, with the online geometry of the emitter connectors, that allows an easy quantification of such head loss regarding of the size of the connectors. The experiment was carried out according to the Reynolds Numbers at a turbulent flow interval, obtained by the variation of the pipe outflow at a constant temperature of water. The results indicated that the friction factor of the Darcy-Weisbach equation can be estimated by the Blasius equation with the coefficients b = 0.300 and m = 0.25, for the above mentioned pipes. The head losses produced by the connections of the emitters, in relation to the pipe without emitter, was of 62%. A relationship between the kinetic load coefficient (K) and the index of blockage (IO) provoked by the online connector is presented by an algebraic equation which shows a coefficient of adjustment of approximately 96%.

Avaliação da perda óssea alveolar em pacientes encaminhados à especialista em periodontia: estudo radiográfico

The aim of this study was to evaluate the mean of alveolar bone loss (%) in radiographies of patients referred to specialist for periodontal treatment. Full mouth series of periapical radiographies (paralelism technique) were used. A total of 9808 proximal surfaces in 4804 teeth of 213 patients (90 males and 123 females), mean age, 44.3 years, were assessed. The alveolar bone loss was measured in relation to root lenght expressed as an average similar to Schei 's technique (1959) without the use of ruler. The references used were the distances cement-enamel juntion (CEJ) - alveolar crest (AC) and CEJ- dental apex taken with a digimatic caliper. The results showed that the mean values of alveolar bone loss (%ABL) was 22.39%. Men showed higher mean values of %ABL than women; the %ABL increased with the age, but the difference among age groups was no statistical significant (p>0.05); the mean values of %ABL of distal surfaces was higher than mesial surfaces (p<0.01), ríght quadrants exhibited higher %ABL values than left quadrants (p<0.01); maxillary sites showed mean values of %ABL higher than mandibular sites; the highest mean values of %ABL was found in molar group, followed by incisor groups, and premolar group; the canine group exhibited lower mean values of %ABL; the differences among the groups was considered statitistically significant (p<0.01). lt was suggested the usage of this technique in the dentistry offices and radiological services for the patient 's documentation and assortment and for later comparison about alveolar bone level

Perda óssea em prótese sobre implante: revisão de literatura

One of the complications that concern prosthetists is bone loss peri-implant, because the success of dental implant treatment requires long-term maintenance of hard and soft tissues around the implant. Whereby the dental implants have not only the goal of restoring function, but also the aesthetics of the patient, the bone loss peri-implant can dramatically compromise the aesthetics of rehabilitation, particularly in anterior regions. The aim of this study was to analyze and reason, through literature review, the main factors that can cause bone loss in peri-implant and possible ways to prevent it.

Deficiência auditiva: estudos clínicos sobre o narcisismo materno

The diagnosis of hearing loss (HL) in a child constitutes a crisis, includinga possible crash in parental narcissism, requiring an individual, matrimonial andfamiliar reorganization process. The mother is the main figure to devote herselfattending the baby and generally takes the most responsibilities in the processof habilitation or rehabilitation of the child, while still having to deal with her frustratedexpectations and narcissism. This study aims to investigate the effects of a deaf child’s birth on the mother’s narcissism. Here understood as a normal stage of psychosexual development of the human being, needed for life preservation, nota pathology. Five different clinical pratical studies were developed with mothers of deaf children that were diagnosed less than one year ago. The data were collected using individual semi-structured interviews and Thematic Apperception Test (TAT). Based on these studies it was found that the birth of a deaf child makes it difficult to obtain the expected narcissist satisfaction. The mother, investing all her affection and longing almost only on her child, hopes to rebuild her dream obtaining the "cure" and "normality" of her baby by submitting him/her to a cochlear implant.

Práticas educativas parentais: a deficiência auditiva pode fazer a diferença?

This study analyzed the influence of the hearing impairment (HI) of children in the way their mothers treat them (between 5 and 12 years old). Two studies were carried out to investigate the social - educational parental practices (SEPP) and parental styles. The first study observed the parental educational practices of mothers dealing with children with and without HI, and the second study tried to verify whether mothers acted different in these same practices when considering either children with HI or children without HI. The results have shown that HI seems to modify SEPP concerning expressing opinions, asking questions, (Study 1) and setting limits (Studies 1 and 2), as well as practices of negative monitoring (Study 1), moral behavior, inconsistent punishment, discipline absence, physical abuse and, also, Parental Styles (Study 2).
