Participated 71 athletes of both genders, age varying between 15 and 35 years, from the judo, olympic gymnastics, volleyball, soccer and 27 nonathletes. The evaluation of sensibility was performed with Semmes-Weinstein® monofilaments and the AMTI, model OR6-5 force plate was used to verify COP sway. Data collection was composed by: a) to sensibility evaluation each filament was applied in calcaneal region, middle foot, first and fifth metatarsal heads and halux. The sensibility threshold was determined by the filament with the smaller diameter felt by the individual; b) the individual was oriented to stand on the force plate, with the feet lightly distant and the arms along side the body, in the bipodal and unipodal positon, with footwear and without footwear, with and without visual information. The sampling frequency was of 50Hz and time of acquisition of 30s (bipodal) and 20s (unipodal). Descriptive statistics (mean, standarddeviation, mediana and variation coefficient), inferencial (Anova 3x2x2) and non-parametric (Kruskall-Wallis test, U of Mann-Whitney s test and Correlation of Spearman) were used as statistical procedures. Results: The sensibility thresholds were between 4.31 and 3.61. The region with the worst and the best sensibility threshold were respectively the calcaneal region and the middle foot, for all the groups. The athletes of the practice with footwear had the largest values for the variables of the Center of Pressure, in the bipodal and unipodal position. There was no statistic difference between the groups for the variables of the Center of Pressure in the bipodal position. In the unipodal position the variables, except RMS, suffered effect of the visual information, with the largest increment observed for the area of displacement of COP (326,8%). To bipodal and unipodal position were possible to verify low correlation among the plantar sensitibility and static balance. Conclusion: except for the calcaneal region, the other areas there were no significant difference between the groups. The athletes that compete with footwear (volleyball and soccer) were more dependents of the visual information that the athletes of olympic gymnastics and judo and non-athletes. / Este estudo descritivo exploratório objetivou analisar as características e a relação entre a sensibilidade plantar e o equilíbrio na postura em pé de atletas cuja prática da modalidade é descalço, atletas cuja prática é com calçado e indivíduos não-atletas, nas condições com e sem informação visual e com e sem calçado. Participaram do estudo 71 atletas de ambos os sexos, com idade entre 15 e 35 anos, das modalidades de judô, ginástica olímpica, voleibol, futebol e 27 indivíduos não-atletas na mesma faixa etária. Os instrumentos foram: monofilamentos Semmes-Weinstein® e plataforma de força extensométrica AMTI® modelo OR6-5. Adotou-se os seguintes procedimentos de coleta: a) na avaliação da sensibilidade cada filamento foi aplicado nas regiões de calcâneo, médio pé medial, I e V metatarso e hálux. O nível de sensibilidade foi determinado pelo filamento com o menor diâmetro sentido pelo sujeito, ao responder 6 tentativas positivas, de um total de 10; b) os sujeitos foram orientados verbalmente a permanecer sobre a plataforma de força, com os pés ligeiramente afastados e os braços ao longo do corpo o mais imóvel possível, nas posições bipodal e unipodal, com calçado e sem calçado, olhos abertos e olhos fechados. A freqüência de amostragem foi de 50Hz com tempo de aquisição de 30s (bipodal) e 20s (unipodal). Utilizou-se estatística descritiva (média, desvio-padrão,mediana e coeficiente de variação), inferencial (Anova 3x2x2) e não-paramétrica (Teste da mediana de Kruskall-Wallis, teste U de Mann-Whitney e Correlação de Spearman) a p 0,05.Obteve-se os seguintes Resultados: Os níveis de sensibilidade estiveram entre 4.31 e 3.61, sendo o pior na região do calcâneo e o melhor na região do médio (3.61), para todos os grupos. Os atletas da prática com calçado tiveram os maiores valores para todas as variáveis do Centro de Pressão, tanto na posição bipodal quanto unipodal. Na posição bipodal todas as variáveis do Centro de Pressão foram semelhantes para os três grupos. Na posição unipodal as variáveis, com exceção do RMS, sofreram efeito da retirada da informação visual, com o maior acréscimo observado para a área de deslocamento do COP (326,8%). Para as posturas bipodal e unipodal considerado a mediana de toda a planta do pé foi possível constatar baixa correlação entre a sensibilidade plantar e variáveis de equilíbrio. Concluiu-se que exceto para a região do calcâneo, pior nos atletas da prática com calçado, nas demais áreas parece que a prática de modalidades com ou sem calçado não influencia na sensibilidade plantar. Para posição bipodal o fato de praticar modalidades com uso ou não de calçado, e ser ou não atletas parece não influenciar as variáveis. Os atletas que treinam e competem utilizando calçado (modalidade de voleibol e futebol) foram mais dependentes da informação visual que os atletas de ginástica olímpica e judô e indivíduos não atletas.

O ciclo de operação de um compressor alternativo é descrito por uma série de fenômenos complexos ocorrendo em um curto período de tempo. Dentre os fatores considerados importantes para e ciência termodinâmica dos compressores, destacam-se as válvulas que controlam os processos de sucção e de descarga, que são responsáveis por grandes perdas termodinâmicas no ciclo.

Como uma forma de reduzir os problemas gerados pelas instabilidades no funcionamento da válvula de sucção, propomos a utilização de um esbarro para limitar a abertura máxima da válvula, reduzindo sua instabilidade e aumentando a e ciência do compressor. Mostramos experimentalmente que existe uma posição de equilíbrio que mantém a válvula aberta sem instabilidades e que esta posição varia, aproximadamente, linearmente com o número de Reynolds. / Most of the vapor refrigeration systems use reciprocating compressors, which are considered important mechanisms in the modern era. The cycle of operation of a reciprocating compressor is described by a series of complex phenomena ocurring in a short period of time. Among the factors considered important for the thermodynamic efficiency of compressors are the valves that control the suction and discharge processes, which are responsible for large cycle thermodynamic losses. Part of that losses occurs in the valves system, particularly in the suction valve, where the movement instabilities reduce the efficiency of the suction process. In order to reduce the instabilities of the suction valve, we propose the use of a stop to limit the maximum aperture of the valve, reducing its instabilities and increasing the compressor efficiency. We show experimentally that does exist an static equilibrium position in which the valve remains opened without oscillation and that position varies almost linearly through the Reynolds number.

Submitted in partial compliance with the requirements for the Master of Technology: Chiropractic, Durban University of Technology, 2014. / Background: Poor balance is a risk factor for injury in adolescent sport including soccer. Despite the rapid growth in female adolescent soccer especially in South Africa, the association between balance and injury in this population has not been fully explored. This study aimed to determine the relationship between injury and balance. Static and dynamic balance was monitored as sway index (SI) and limits of stability direction control (LOSDC). Objectives: The objectives of this study were to determine the body mass index of adolescent female soccer players; to determine the prevalence of injury in adolescent female soccer players; to determine static balance as revealed by the sway index (SI); to determine dynamic stability as revealed by limits of stability direction control (LOSDC) and to correlate body mass index (BMI) to sway index and limits of stability. Method: Eighty adolescent female soccer players, between the ages of fourteen and eighteen, were recruited through convenience sampling from schools in the eThekwini district of KwaZulu-Natal. After obtaining informed consent and assent, participants completed questionnaires and were scheduled for the balance and BMI assessments. The objective data for each participant consisted of height, weight, Sway Index (SI) and Limits of Stability Direction Control (LOSDC) readings, measured using a stadiometer, electronic scale and Biodex Biosway Balance System (Biodex Medical Systems Inc., Shirley, New York) respectively. The subjective and objective data were analyzed using SPSS version 21.0 (SPSS Inc. Chicago, Ill, USA). Statistical tests included descriptive statistics using frequency and cross-tabulation. Inferential statistics using t-tests and Pearson’s correlations at a significance level of 0.05 was also incorporated. The testing of hypotheses was performed using Fisher’s Exact tests for nominal data and ordinal data. A p value of < 0.05 was considered as statistically significant. The statistical analysis also included Odds Ratio calculations. Results: The mean body mass index of the injured participants was 23.54±3.56 kg/m2 and the mean body mass index of the uninjured participants was 23.00±4.63. Only 27.5% of the participants sustained an injury. Injured participants performed poorly on average in the SI assessment involving their eyes open when standing on a soft surface. The results were similar for the LOSDC in the overall, right, left, backward-right and backward-left directions. However, there were no significant correlations calculated. Significant relationships existed between BMI and the SI assessments in the injured participants which involved standing on a firm surface with their eyes open (p = 0.05), their eyes closed when also standing on a firm surface (p = 0.05), their eyes open when standing on a soft surface (p = 0.02), and their eyes closed when standing on a soft surface (p = 0.04). A significant relationship also existed between BMI and LOS right direction control (p = 0.02). Conclusion: This research paper revealed that the body mass index as investigated in this study is similar to other studies involving female adolescents; soccer injury as investigated in this study is similar to other studies involving female adolescents; poor static and dynamic balance is not associated with injury in adolescent female soccer players and lastly, body mass index is linked to the balance of an individual.

The central integration of sensory information provided by various afferent receptors is required to control human movement. Although the function of individual afferent receptors is known, the complexity and interactivity of afferent information remains unclear, especially in scenarios which involve the reduction of information provided by one or more afferent receptors. Reduced plantar sensitivity is commonly associated with postural instability, which occurs in ageing, peripheral neuropathies, and other neurological disorders like Parkinson's disease. Although there has been a great advance in understanding afferent inputs during recent years, the role of afferent information in controlling movement is still unclear. Therefore, the aim of the present thesis is to investigate the effects of reduced plantar sensitivity on quasi-static and dynamic balance control, as well as muscle reflexes. The current thesis is comprised of five experiments. Two experiments were designed as preliminary investigations, while the remaining three experiments addressed the main questions of this thesis. The first experiment investigated a basic question about subjective foot sensitivity (vibration perception) measured in two different body positions: standing and sitting. Results of Experiment I showed no differences of vibration perception between both measured conditions. Therefore, comparing data from plantar sensitivity vibration tests performed during sitting and during standing (e.g. balance) is feasible. In Experiment II, the role of afferent information from plantar mechanoreceptors on quasi-static balance was investigated using two different cooling procedures: a permanently cooling thermal platform and conventional ice pads. COP total excursions, plantar temperatures, and scores of a Visual Analogue Scale (VAS) regarding subjective pain were analyzed. Experiment II demonstrated that constant and controllable cooling via the thermal platform is the superior approach with respect to subjective pain (VAS) and to reach and maintain the desired temperature throughout the trials. Furthermore, only cooling via the thermal platform induced postural instability, revealed by increased COP values. This instability was expected due to reduced plantar input, indicating no compensation by other sensory systems. Experiment III focused on the inter- and intraday- reliability of dynamic balance responses using the Posturomed device. Generally good relative and absolute reliability were found for COP excursions. This outcome was fundamental to proceed with dynamic balance measurements using the same setup. Subsequently, effects of reduced plantar cutaneous inputs via cooling on anticipatory and compensatory balance responses (unexpected perturbations) were explored in Experiment IV. COP and EMG data were used to analyze anticipatory and compensatory balance responses. No differences in COP or EMG parameters were found for the anticipatory responses after hyper-thermia, while decreased values for compensatory balance responses were observed in response to cooling. This was interpreted as a kind of overcompensatory behavior of the central nervous system (CNS) due to more cautious behavior induced after plantar cooling. Finally, the question regarding the interaction between afferent receptors arose in Experiment V, in which the effects of reduced plantar temperatures on the Achilles tendon stretch reflex and plantar flexion were examined. Short latency responses and maximal force of plantar flexion were analyzed. Cooling resulted in decreased amplitudes of short latencies, as well as in delays in time to maximal force of plantar flexion. These findings suggest that plantar inputs participate complementarily in the Achilles stretch reflex. Collectively, the current thesis contributes to understanding how plantar receptors are involved in movement control; not only do they seem to work as independent contributors, but they also appear to interact with other afferent receptors. Furthermore, an important outcome is that the reduced plantar inputs seem to induce different alterations in the organization of CNS inputs and outputs, according to different balance tasks: quasi-static responses, anticipatory responses, and compensatory responses. For the future, the use of other methods like microneurography and electroencephalography could be helpful to gain even more understanding of afferent interactions during the control of movements. Similar protocols may also be implemented in other populations, such as elderly people or patients suffering from neurological disorders, who exhibit continued decline or degeneration of sensory receptors. / Die zentrale Integration von sensorischen Informationen, die aus verschiedenen afferenten Rezeptoren zur Verfügung gestellt werden, ist erforderlich, um die menschliche Bewegung zu steuern. Obwohl die Funktion der einzelnen afferenten Rezeptoren bekannt ist, bleibt die Komplexität und Interaktivität von afferenten Information unklar, insbesondere in Szenarien, in denen die Verminderung von Informationen aus einem oder mehreren afferenten Rezeptoren eintritt. Reduzierte plantare Sensibilität wird häufig im Zusammenhang mit Haltungsinstabilität verbunden. Dies tritt häufig während des Alterns ein, bei peripheren Neuropathien und anderen neurologischen Erkrankungen, wie etwa bei der Parkinson-Krankheit. Obwohl es in den vergangen Jahren große Entwicklungen was das Verständnis afferenter Inputs gab, ist die Rolle afferenter Information bei der Bewegungskontrolle immer noch unklar. Daher ist das Ziel der vorliegenden Dissertation, den Einfluss der Beeinträchtigung der plantaren Sensibilität auf das quasi-statische und dynamische Gleichgewicht, sowie auf den Reflex der Achillessehne, zu untersuchen. Die vorliegende Dissertation ist dazu aus fünf Untersuchungen aufgebaut. Zwei Untersuchungen werden als Voruntersuchungen präsentiert, während die übrigen drei Untersuchungen auf die Kernfragen dieser Doktorarbeit gerichtet sind. Die erste Untersuchung beschäftigt sich mit der grundlegenden Fragestellung bzgl. der subjektiven Fußsensibilität (Vibrationswahrnehmung), die in zwei verschiedenen Körperpositionen gemessen wurde: Im Stehen und im Sitzen. Ergebnisse aus Untersuchung I zeigten keine Unterschiede der Vibrationswahrnehmung zwischen den beiden Körperpositionen. Daher ist es möglich, Vergleiche zwischen Daten aus plantaren Vibrationswahrnehmungstests während des Sitzens und des Stehens (z.B. bei Gleichgewichtstests) durchzuführen. In Untersuchung II wurde die Rolle afferenter Informationen plantarer Mechanorezeptoren auf das quasi-statische Gleichgewicht mittels zwei unterschiedlicher Abkühlverfahren untersucht: eine permanente Abkühlung durch eine thermische Plattform und konventionelle Eis-Pads. Es wurden der COP Gesamtweg, plantar Temperaturen und eine visuelle Analogskala (VAS) in Bezug auf subjektive Schmerzen analysiert. Untersuchung II hat gezeigt, dass eine konstante und steuerbare Abkühlung über die thermische Plattform der überlegene Ansatz in Bezug auf subjektiven Schmerz (VAS) und bzgl. des Erreichens und Erhaltens einer gewünschten Temperatur innerhalb der Messungen ist. Weiterhin wurde nur durch die Abkühlung mittels thermischer Plattform eine posturale Instabilität induziert, evident durch erhöhte COP Gesamtwege. Diese Instabilität wurde aufgrund der Beeinträchtigung der plantaren Sensibilität erwartet, was auf eine fehlende Kompensation durch andere Sinnessysteme hinzuweisen scheint. In Untersuchung III lag der Fokus auf der inter- und intra-Tag-Reliabilität dynamischer Gleichgewichtsantworten mittels des Posturomed-Trainingsgerätes. Im Allgemeinen wurden eine gute relative und absolute Reliabilität der COP Gesamtwege ermittelt. Dieses Ergebnis war von grundlegender Bedeutung, um die Nutzung des gleichen Setups für die folgenden dynamischen Gleichgewichtsmessungen (Untersuchung IV) zu ermöglichen. Anschließend wurden die Effekte einer Beeinträchtigung der plantaren Sensibilität mittels Abkühlung auf antizipatorische und kompensatorische Antworten des dynamischen Gleichgewichts (anhand unerwarteter Störungen des Gleichgewichts) in Untersuchung IV erforscht. COP und EMG Daten wurden verwendet, um die antizipatorischen und kompensatorischen Antworten des Gleichgewichts zu analysieren. Nach der Abkühlung wurden bzgl. antizipatorischer Antworten keine Unterschiede in den COP und EMG Parametern gefunden. Im Hinblick auf kompensatorische Antworten zeigten sich reduzierte COP und EMG als Reaktion auf die Abkühlung. Dies wurde wie folgt interpretiert: aufgrund eines vorsichtigen Verhaltens, ausgelöst durch die verminderten sensorischen Inputs infolge der Abkühlung, kam es zu einer Art „Überkompensierungsverhalten“ des zentralen Nervensystems (ZNS). Schließlich stellte sich die Frage der Interaktion afferenter Rezeptoren in Untersuchung V, in welcher die Effekte reduzierter plantarer Temperaturen auf den Achillessehnen-Dehnungsreflex und die Plantarflexion untersucht wurden. Kurze Latenz Antworten (short latency responses) und die maximale Kraft der Plantarflexion wurden dabei analysiert. Die Abkühlung führte zu einer verminderten Amplitude der short latency responses sowie zu Verzögerungen der Zeit bis zur maximalen Kraft der Plantarflexion. Diese Ergebnisse deuten darauf hin, dass plantare Inputs in komplementärer Weise am Achillessehnen-Dehnungsreflex beteiligt sind. Zusammenfassend lässt sich aussagen, dass die vorliegende Arbeit zum Verständnis beiträgt, wie plantare Rezeptoren an der Bewegungssteuerung beteiligt sind. Es scheint, dass diese nicht nur in unabhängiger Form zur Bewegungssteuerung beitragen, sondern dabei auch mit anderen afferenten Rezeptoren interagieren. Darüber hinaus ist ein wichtiges Resultat, dass die reduzierten plantaren Inputs scheinbar verschiedene Änderungen in der Organisation von Ein- und Ausgängen im ZNS induzieren. Dies erfolgt anhand unterschiedlicher Anforderungen an das Gleichgewicht: quasi-statische Antworten, antizipatorische Antworten und kompensatorischen Antworten. Für die Zukunft könnte die Implementierung anderer Methoden, wie Mikroneurographie und Elektroenzephalographie, hilfreich sein, um noch mehr Verständnis bezüglich afferenter Interaktionen während der Kontrolle von Bewegungen erlangen zu können. Ähnliche Protokolle könnten auch in anderen Populationen durchgeführt werden, wie ältere Menschen oder Patienten mit neurologischen Erkrankungen, die einen kontinuierlichen Rückgang oder Degenerationen sensorischer Rezeptoren zeigen.

Dizziness and balance problems are common symptoms at all ages. The aims were; to evaluate rehabilitation, static, dynamic balance and recovery in acute unilateral vestibular loss (AUVL), to evaluate the treatment of benign paroxysmal positional vertigo (BPPV) with assessment of static and dynamic balance and to evaluate the prevalence of dizziness and BPPV in a population of 75-year-olds. Study 1: Twenty-seven patients (51years) with AUVL were included and the recovery was followed regarding vestibular function, dizziness, and sick-leave. The recovery was rapid, with disappearance of spontaneous nystagmus and rapid return to work. Study II: Forty two patents (51 years) with AUVL were included and compared with a reference group. Static and dynamic balance were assessed after six months. Significant instability was found both in static and dynamic balance compared to a reference group. Study III: Seventeen patients (52 years) with severe BPPV (&gt; 3 months) were treated with Semonts´s manouver and/or Brandt-Daroff exercises. The recovery was evaluated by Dix-Hallpike test, subjective dizziness, unsteadiness and balance tests, after 1, 6 and 12 months. Semont´s maneouver resolved dizziness but the long term follow up showed impaired balance. Study IV: A large cohort (675) of elderly was assessed regarding dizziness and BPPV. Side lying test and balance tests were applied. A high prevalence of dizziness (36%) and BPPV (11%) was found. Conclusions: Patients with AUVL and BPPV have despite good symptomatic relief, still impaired static and dynamic balance at long term follow up. BPPV in elderly is common and should be examined since it can be treated.

The study sample consisted of 11 children and adolescents with Down Syndrome and 14 healthy children and adolescents, in the control group. During the vídeo takes all the subjects were instructed to stay in the orthostatic position with the arms along the body and feet parallel in a flat surface, looking at a target set at the eyes height on the wall in front os them. Children of both groups were filmed in anterior view (frontal view) and right side view (sagittal view) in these two conditions: with and without vision. During the video takes with the eyes closed, it was used a swimming goggle completely sealed,with the purpose of not allowing the subject to have any visual information. The instument used was the Computerized Biophotogrammetry which served as angular reference to verify the body oscillations in the static balance. The results of this study showed that children and adolescents with Down Syndrome oscillate more than the control group and when the visual information is manipulated both anteroposterior and side-to-side oscillations showed strong evidences (p<0,01) of the presence of differences between children with Down Syndrome and the children in the control group. / O objetivo deste estudo foi avaliar o equilíbrio estático de crianças e adolescentes com Síndrome de Down, e verificar a influencia da visão no equilíbrio estático. Participaram do estudo 11 crianças e adolescentes com SD e 14 crianças e adolescentes neurologicamente normais, que compuseram o grupo controle. Durante as filmagens os participantes se mantiveram na posição ortostática com os braços posicionados ao lado do corpo com os pés paralelos sobre uma superfície plana, olhando para um alvo posicionado na parede frontal da sala na altura dos olhos. As crianças de ambos os grupos foram filmadas na vista anterior (plano frontal) e na vista de perfil direito (plano sagital) nas condições com visão e sem visão. Nas filmagens na condição de olhos fechados, foi utilizado um óculos de natação totalmente vedado, com a finalidade do participante não ter nenhuma informação visual. O instrumento utilizado foi a Biofotogrametria Computadorizada que serviu como referência angular para verificar as oscilações do corpo em equilíbrio estático. Os resultados deste estudo mostraram que as crianças e adolescentes com SD oscilam mais que o grupo controle e, quando a informação visual é manipulada às oscilações tanto ântero-posterior como latero-lateral mostraram fortes indícios (p<0,01) da existência de diferenças quando comparadas com as crianças do grupo controle.
