Повний текст джерелаObjetivo: Comparar a pressão plantar e a velocidade do deslocamento do centro de pressão (CdP) entre pés normais, cavos e planos em indivíduos adultos saudáveis. Metodologia: foi realizado um estudo observacional, com 26 indivíduos saudáveis, classificados com pés normais (n=22), pés cavos (n=6) e pés planos (n=24) baseado no Foot Posture Index – 6. Os indivíduos caminharam normalmente ao longo de um espaço de 10 metros, enquanto usavam um sistema de análise de pressão plantar F-scan (Tekscan). Utilizaram-se 5 áreas que incluíram o retropé, médiopé, antepé, dedos e pé total. A pressão plantar máxima (PPmáx) e o integral pressão-tempo (IPT) e o centro de pressão (CdP) foram calculados para cada área. Resultados: não foram encontradas alterações significativas (p> 0,05) entre as variáveis PPmáx e o IPT com o arco plantar, no entanto foram encontradas alterações significativas para a velocidade do CdP com o arco plantar (p <0,05). Conclusão: este estudo confirma que o arco plantar longitudinal medial influencia algumas variáveis de pressão plantar, nomeadamente a velocidade do CdP.
Objective: To compare plantar pressure and the velocity of center of pressure (COP) displacement between normal, cavus and planus foot in healthy adult subjects. Methods: An observational study was performed with 26 healthy individuals classified as normal feet (n = 22), cavus feet (n = 6) and planus feet (n = 24) based in the Foot Posture Index - 6. Individuals walked normally over a 10 meters span, while using an F- scan (Tekscan) plantar pressure analysis system. Five areas were used that included the hindfoot, midfoot, forefoot, toes and total foot. The peak pressure (PP), integral pressure-time (PTI), center of pressure (COP) were calculated for each area. Results: no significant changes (p> 0.05) were found between the variables peak pressure (PP), total pressure-time integral (PTI) with the plantar arch, but significant changes were found for the velocity of center of pressure (COP) with the plantar arch (p <0.05). Conclusion: this study confirms that the medial longitudinal plantar arch influences some plantar pressure variables, namely the velocity of COP.

The aim of this correlational study was to analyze the plantar medial longitudinal arch during the stance phase of the gait. Thirty-two subjects of both genders (mean age 25,78±6,75 years) from Vale dos Sinos RS have participated of the research. The specific objectives was to describe the behavior of the plantar medial longitudinal arch during the gait in the initial contact and stance phase; identify the foot s angle with the surface in the initial contact; correlate the medial longitudinal plantar arch with the Ankle s angle during the contact phase; correlate the anthropometry variables with the dynamic behavior of the medial longitudinal plantar arch; correlate the plantar pressure distribution (peak pressure, plantar pressure mean, contact time and mean area) with the dynamic behavior of the kinetics and kinematics variables of the medial longitudinal plantar arch during the stance phase and relate the kinetics and kinematics variables with kinds of medial longitudinal plantar arch. The kinematics data has been acquired by the Spica Technology Corporation video system and for kinetic data was used the Novel Emed-XR system with a sampling rate of 100 Hz and the 3D Scanner INFOOT. Subjects were separate into three groups by the Cavanagh s arch index: Cavus foot; normal foot e planus foot. The variables analyzed were: medial longitudinal plantar arch angle in seated position, initial contact and stance phase, angle of the ankle in seated position and stance phase, plantar pressure of peak, mean plantar pressure, contact area, contact time and mean force. The Kolmogorov-Smirnov test has been applied for the statistical analysis to verify the normality of the data. The ANOVA One-Way test has been used to compare means intra-groups and to verify where were the differences was used the Scheffé`s Post Hoc test. Pearson test has been applied to verify the correlation. The level of significance adopted was p ≤ 0.05. There were no differences statistically significant when inter-groups kinematics and anthropometrics variables had been compared. Only in some regions of the plantar surface has shown differences statistically significant when the kinetics variables were compared inter-group. Analyzing the correlations between the dynamic arch index with kinematics variables, only the medial longitudinal plantar arch angle has shown a moderate correlation statistically significant, while others correlations had low relations.

Na análise estatística foi aplicado o teste de Kolmogorov-Smirnov para verificar a normalidade nos dados. Na comparação das médias intra-grupos foi aplicado ANOVA One-Way e para verificar onde as diferenças encontravam foi utilizado o teste de Post hoc de Scheffé. Para verificar as correlações foi aplicado Pearson. O nível de significância adotado foi de p≤ 0,05. Na comparação inter-grupos para as variáveis cinemáticas e antropométricas, não apresentaram diferenças estatisticamente significativas. Apenas na comparação inter-grupos das variáveis cinéticas, em algumas regiões da superfície plantar apresentaram diferenças estatisticamente significativas. Ao analisar as correlações entre o Índice do Arco Plantar dinâmico com as variáveis cinemáticas, somente o ângulo do Arco Plantar longitudinal medial apresentou correlação moderada estatisticamente significativa, as demais variáveis cinemáticas apresentaram correlações baixas.

Повний текст джерелаRational: Research on the anatomy of the aortic arch has been fueled by the need of a comprehensive analysis of this structure in the setting of endovascular repair. Aneurysmal disease causes distortions in areas where the implantation of stent grafts undergo major stress. Objectives: I: To characterize the morphometric modifications of the aortic arch induced by a thoracic aneurysm. II: To evaluate the feasibility of current endovascular devices in treating aortic arch aneurysms. III: To create an automated measurement tool for assessing the angulations induced by these deformations. IV: To validate a 0D numerical simulation model of vascular mechanics by comparing its predictions with in vivo data.Results: I: In a study of 78 CT scan, thoracic aneurysms were associated with bi-directional wall stretching and anterior or posterior rotation according to the aneurysm’s location. II: A retrospective study of the CT scans of 56 patients who underwent aortic arch aneurysm surgical repair showed that none of these patients had the anatomical criteria for a stent graft implantation. III: An automated software for calculating the aortic angulations from a continuous analysis of the curvature radius of the central line was developed and validated against the visual assessment of points. IV: Changes in the morphology of blood pressure waves after aortic clamping and unclamping were studied in 11 patients with a good correlation and agreement between the numerical model and continuous intravascular measurements. Conclusion: Advances in the analysis of aortic geometry and the simulation of vascular mechanics are necessary for the adaptation of new endovascular devices

Повний текст джерелаChanges in cathode, arc and emission properties were noted with respect to vacuum, argon and nitrogen ambients. The introduction of nitrogen, above a critical pressure ($ sim$1 $ times 10 sp{-3}$ Torr), increased arc velocity and decreased crater diameter, erosion rate and ion emission. This occurred when arc rotation was combined with nitrogen introduction. Thermal properties of the cathode during arcing seemed to play an important role in determining the extent of nitrogen-cathode interaction. X-ray photoelectron spectroscopy (XPS) analysis has shown that nitriding occurred within the regions of arcing and was dependent on nitrogen pressure (with all other parameters remaining constant). The most encouraging result found was the complete elimination or macroparticles normally present in the coating/film.

Повний текст джерелаFault electric arcs occurring between two damaged wires may lead to a phenomenon called "arc tracking", which consists in a maintaining and propagating arc along the cables, causing their progressive ablation. In an aeronautical network, such a fault may have serious consequences if it happens within a wiring harness, especially as it is likely to transfer to a nearby structure. An experimental setup has been developed to study this phenomenon. It consists of a power supply designed in accordance with aeronautical specifications, which enables to generate a direct or alternating signal during an adjustable time. In order to reproduce flight conditions in a better way (low pressure at high altitude), tests are carried out within a closed chamber, whether at 1 bar pressure, or at 95 mbar pressure. Three types of cables are tested, one mainly made of aluminium and two mainly made of copper. In direct regime, they are connected to the + and the - poles of the generator, and to two phases in alternating regime. An aluminium plate, representing the aircraft structure and connected to the neutral in alternating regime, is placed in front of the stripped part of the cables, where the arc occurs, enabling a potential transfer of the arc from the cables toward the plate. Every test involves a systematic acquisition of the current and voltage signals, and two radiative flux sensors are positioned around the arc. A fast camera enables a viewing of the arc behaviour during the test. Finally, the sample is weighed before and after each test. A power balance is realised for the various tested configurations (current, pressure, cables), in order to estimate the distribution of the total power between the electrodes (fusion and vaporisation of the cables, but also conduction and radiation) and the plasma column (radiation, conduction, convection). The amount of power that is transferred to the electrodes is estimated with the value of the electrode voltage drop and the current. Part of this power makes the cables melt and vaporise (the insulating material as well as the metal), it is estimated with a thermodynamic calculation based on the ablated mass of cable, considering that the whole has been molten, and 1% vaporised. The amount of power transmitted to the arc column is partly radiated, but the wavelength spectrum emitted below 200 nm is absorbed through the very first microns in air, and estimation is made involving the calculation of the net emission coefficient. A significant part of the study was related to the transfer of the arc toward the aluminium plate, as a function of the distance between the cables and that plate, and according to a temperature criterion at the back side, by means of infrared thermography. Thus, it was shown that at low pressure, the arc is much less localised, and tends to transfer to the aluminium plate at distances around twice bigger than at atmospheric pressure. However, the total available power is around 20% smaller, and the damage caused to the aluminium plate is less severe

Повний текст джерелаTiivistelmä Tiikeri on nykyisin uhanalainen lajin elinympäristön supistumisen ja pilkkoutumisen vuoksi. Lajin tärkein esiintymisalue on Intian niemimaalla, joka on siten kriittisen tärkeä alue tiikerin suojelun kannalta. Intiantiikereitä esiintyy useilla pienillä suojelualueilla Intiassa. Kaksi tärkeää tiikerin esiintymisaluetta Intiassa ovat Terain kaaren (TAL) alue luoteis-Intiassa sekä Sundarbansin mangrovealue Bangladeshin rajalla. Näiden alueiden tiikereistä ei ole ollut olemassa geneettistä perustietoutta, jota tarvitaan, kun arvioidaan ihmisen toiminnan ja ilmastonmuutoksen aiheuttamia muutoksia tiikeripopulaatioiden geneettisessä koostumuksessa sekä kun määritellään lajin suojelun kannalta merkittäviä luonnonsuojeluyksikköjä. Tässä väitöskirjatutkimuksessa tutkittiin Terain kaaren ja Sundarbansin alueen tiikereiden geneettistä monimuotoisuutta ja rakennetta sekä tuman että mitokondrion geenimerkkien avulla. Tutkimuksessa selvitettiin kolmenkymmenyhdeksän tuman geenimerkin (mikrosatelliitin) soveltuvuutta intiantiikerin geneettisiin tutkimuksiin, ja näistä valittiin kolmetoista käytettäväksi läntisen Terain kaaren ja Sundarbansin alueiden tiikereiden geneettisiin tutkimuksiin. Terain kaaren alueelta tutkittiin seitsemänkymmenentäyksi intiantiikerinäytettä. Tulosten perusteella alueella on aikaisemmin havaitsematonta kryptistä populaatiorakennetta. Geenivirtaa eri alapopulaatioiden välillä oli kohtuullisen paljon, mutta se oli epäsymmetristä. Tiikereiden geneettinen monimuotoisuus oli melko suurta eikä geneettisillä menetelmillä havaittu eri alapopulaatioissa merkkejä populaation koon pullonkauloista. Jotta alapopulaatioiden välinen yhdistyneisyys säilyisi jatkossa, joidenkin kylien siirto toisaalle on välttämätöntä. Ihmisten luvaton levittäytyminen tiikerin elinalueita yhdistävillä käytävillä täytyisi saada hallintaan sekä kieltää hiekanotto ja kivenlouhinta. Sundarbansin alueelta ei-invasiivisesti kerätyt tiikerinäytteet tutkittiin sekä tuman että mitokondrion merkkigeenillä ja alueen tiikereiden geneettistä koostumusta verrattiin manner-Intian tiikeripopulaatioiden koostumukseen. Sundarbansin tiikereiden todettiin poikkeavan geneettisesti manneralueen tiikeripopulaatioista ja niiden geneettinen monimuotoisuus oli alhaisempaa kuin manneralueella. Koalesenssisimulaatiohin perustava demografinen analyysi viittasi Sundarbansin tiikereiden suhteellisen viimeaikaiseen (600—2000 vuotta sitten) erkanemiseen manneralueen tiikereistä. Sekä historialliset että geneettiset todisteet tukivat teoriaa, jonka mukaan Sundarbansin tiikereillä olisi ollut yhteyksiä mannermaan tiikereihin aivan viime aikoihin asti. Geneettinen isolaatio mannermaan tiikereistä ja adaptaatio mangrove-ekosysteemiin ovat yhdessä muovanneet Sundarbansin tiikereiden geneettistä arkkitehtuuria. Tämän vuoksi Sundarbansin tiikerit vaativat erityistä suojelua, jotta niiden geneettinen ainutlaatuisuus ja kyky sopeutua erityisolosuhteisiin säilyisivät myös tulevaisuudessa. Populaatiota täytyy hoitaa evolutiivisesti merkittävänä yksikkönä (evolutionary significant unit; ESU) adaptiivisen evolutiivisen suojelun (adaptive evolutionary conservation; AEC) kriteeristön mukaisesti. Tutkimuksessa kiinnitettiin huomiota myös ongelmiin, joita saattoi ilmetä aikaisemmin ehdotetuissa menetelmissä eri sukupuolten kautta kulkevan geenivirran määrän arvioimiseksi ja ehdotettiin vaihtoehtoista menetelmää tarkempien arvioiden saamiseksi

Повний текст джерелаLow-Voltage Circuit Breakers (LVCB) are classical apparatuses of electrical distribution since more than fifty years. But nowadays, with the outbreak of low-cost products from the developing countries, industry is under a strong stress in order to improve their devices by making them more compact, using different materials or to implement new functionalities. This research is harsh since LVCB are highly multiphysics systems (mechanics, thermal properties, materials, plasma physics, ...). Therefore, developing new products goes through a long and expensive empirical process. Those efforts could be reduced by using predictive models allowing to get faster to a functional device. With the improvements of the numerical solution capacity, there are more and more works toward the 3D multiphysical description of the LVCB, especially on the extinction chamber where the electrical arc is ignited, moved and must be quenched. This is the subject of our work. The study described here is divided in two complementary parts: development of a 3D fluid model with finite volume method simulating the electrical arc and its movement inside the arc extinction chamber; and the set-up of experimental means to analyse this physical phenomenon. For those two points, we use a simplified LVCB configuration with an arc moving between two parallel rails inside a rectangular box chamber. Based on AEPPT's know-how, a numerical model is established to simulate thermal plasma. Particularities on this model, due to the application, are the resolution of Biot&Savart law to calculate precisely the magnetic field for the boundary condition and the development of methods to model the arc roots movement and commutation of the arc from the moving contact to the rail. Validation of this model will be done with the same geometry by confrontation with the experiment. Inspired by precedent works we designed a test apparatus with a reactor representing the extinction chamber of the LVCB and an opening mechanism allowing arc ignition by contact opening at a specified speed. Other parameters such as size of the chamber and materials can be modified. Measurements will include high speed imaging and pressure acquisition in several points of the reactor in addition to the classical current and voltage measurements. This experiment is useful for parametric studies with its easy uncoupling of the parameters. Moreover, by highlighting the dominating phenomena for arc movement, this set-up helps in the build-up of the model over and above the experimental validation

Повний текст джерелаThe characterization of the optical properties of fuel drops around the critical pressure is a challenge. The aim of the thesis is to measure the size and the refractive index of fluids under high pressure conditions close to the critical point. For this purpose, an experimental installation of injection of high-pressure drops has been designed. Rainbow refractometry has been developed and adapted to work first on water and ethanol droplets in the pressure range 1 - 40 bar. Evolutions of their index of refraction with the pressure were obtained. For measurements approaching a fluid near the critical point, ethane was selected because its critical point is 48.7 bar and 32.2 ° C. Index refractive measurements on liquid drops of ethane were then carried out in the range 40 - 46 bar and 18 - 25 ° C. A measurement of the refractive index of ethane drops then gives a value of 1.255 ± 0.002

Повний текст джерелаTo further develop high-enthalpy geothermal energy in Lesser Antilles arc, it is necessary to identify possible new key targets, and to better understand the modes of fluids and heat transfers in geothermal reservoirs. The objective of this work is thus to characterize the spatio-temporal evolution of hydrothermalism at the upper plate of the arc in Guadeloupe with a multidisciplinary approach (combined structural, geochemical, mineralogical, petrological and geochronological analyses) focussed on the oldest volcanic complexes of the archipelago. In the north of Basse-Terre Island reveals an arc metamorphism developed under sub-Greenschist facies. The standard thermal state of the arc crust in Guadeloupe thus established shows a brittle-ductile transition located at depths of 3 to 4 km. An exhumed geothermal paleo-reservoir, identified at the south of Basse-Terre Island, indicates a hydrothermal metamorphism developed under Greenschist facies synchronous with the development of schistose corridors and attests for both vertical and lateral hydrothermal fluid transfers at depths between 2 and 3 km. Comparison of the age of the volcanic activity and Ar-Ar dating of the high-temperature hydrothermal phases allows us to estimate a maximum operating time of the paleo-reservoir at 650 ka. Finally, the discovery, the analysis and the K-Ar dating of a new hydrothermal breccia, within the active geothermal system, reveals a link between current geothermal activity and volcanic activity of the Soufrière, interpreted as a distal epithermal system. Our results lead to a conceptual model for the operation of a high-energy geothermal reservoir in the context of an active arc

Abstract******************************************************** ***** Foot can divide into cavus,normal and planus according the height of foot arch.What is called the planus is specially lower in arch height.In normal working,the planus makes large range of motion in rearfoot and height plantar peak pressure on outside metatarsal than normal due to lower arch .And it may make pathological foot in future.In hospital,some suggest that use arch support to improve the defect and some don''t.At present,there isn''t any report about arch support using in planus.So,the main purposeof the thesis is to research the effect of arch support for planus and hope to support reasonable reference when doctor do correcting. For safety,the thesis use footprint including arch index and modified arch index to be a standard for assessing planus.The conditions of experiment include shoe and shoe with 4 fifferent arch support. According to the experiment result of five planus subjects,arch support can reduce the range of motion in rearfoot motion for most subjects.In plantar pressure,the effect of arch support isn''t significant and don''t reduce the peak pressure on outside metatarsal.In gait line,it is almost the same for all conditions.So,according the result,it seems right to use arch support to improve the planus.

The Plantar pressure and arch index of patient for pathological analysis is an important issue in biomechanical field. The results can be used for preventing and treating some diseases like diabetes and paralysis. There were some used plantar pressure measurement methods in clinical research. Harris foot mat use rubber cushion to measure subject’s plantar pressure. Another method adopted electrical pressure sensors to measure the plantar pressure through the changes of electrical resistance and capacitance. In addition, optical system used photo or plastic sensing units to measure plantar pressure. Although the cost of optical measurement system was cheaper than the electric system, the capability of optical system for measuring pressure values performed worse than electric ones. Besides, the present optical system needs auxiliary structure to measure plantar pressure. This study tried to use gray level analysis to build a new system to improve the defect of measuring pressure values, and simplify process of system. This work develops a new optical plantar pressure and arch index measurement system. Instead of the existing photo or plastic sensing units, the present system uses digital optical camera to capture the color change of bare foot standing. Use gray level transformation and image-processing techniques to establish a correlation relation between the plantar pressure and gray level. Furthermore, measuring the divided region surface of foot can easily get arch index. We can measure the pressure distribution, arch index, length, and width of foot through our system. The simple composition of system and interface can help operators to get plantar information of users more convenient than other used methods. Besides, the data measured by this system can be conserved though data base of users and could be applied for foot disease prevention in the future.

In this paper, the fiber Bragg grating (FBG) sensor for strain sensing is discussed. When the sensor is subject to strain, the central wavelength of the FBG may drift, which can reflect the magnitude of the strain. In this study, a special exterior design and package of the sensor are used so that the period of FBG can be changed as pressure is applied, which in turn causes the central wavelength of the reflection spectrum to drift. By analyzing the drift of the central wavelength, the sensed value can be deduced. Based on the structural analysis and experimental results of the pressure sensor discussed in this study, with the arch shape of the exterior structure of the sensor as well as the H-shaped diaphragm, the longitudinally distributed pressure can be converted into the lateral strain of the diaphragm. And then the diaphragm can transfer the strain to the FBG so as to measure the longitudinally applied pressure. The experimental results show that the wavelength drift and the applied positive pressure are highly positively correlated with a correlation coefficient of 0.9983 and pressure sensitivity up to 3.852 ×10- 3 MPa-1.

Foot health is an important part of personal physical activity. From a medical point of view, poor walking posture can cause physical illness. The plantar pressure information can analyze the individual walking gait and posture. For the average person, it is not easy to obtain your own plantar information and the plantar image map, especially the possession and query, which highlights the importance of the plantar information, so we study the smart phone application (application, APP) has been developed to be easy to operate, low in cost, and popular to use. In the development of the arch corretion, any auxiliary equipment that can be connected through the Arduino motherboard and can produce timely processing and precision can accurately and quickly process the pressure center of gravity measurement data through the LCD display. The advantage of using the fine-tuning auxiliary system is that the data is processed efficiently, the operation is convenient, and the adjustment is accurate. Taking the children in the development of the arch as the experimental object, the results were analyzed and the important information of the correction of the arch of the child was obtained. The purpose of this paper is to develop and establish a foot-image image conversion foot and foot arch index data record analysis software, and build a database through the smart phone application (application, APP) software architecture. It is easy to carry, and software development is easier and less costly. Therefore, this development platform is used. And develop the arch correction tool fine-tuning software arch index database, through the cloud to update the data at any time, and thus provide a record change in the correction process of the plantar correction user. Compared with the correction data that can be called up in medical institutions in the past, this software can immediately log in and check the correction record on the smart phone. Like quick access to analytical reference effects. Using these two development system equipment, in the children's arch correction experiment, the analysis results show that the child's arch correction should be timely.

Pregnant women are suffered from low back pain, higher plantar pressure and fall due to rapid weight gain, change of center of gravity and change of musculoskeletal system, especially in third trimester. Foot arch are regarded a main structure of foot to absorb shock and keep balance. When foot arch height become lower, it may cause posture instability and abnormal distribution of planter pressure. If they ignore this issue, the problems will become more and more heavily. A foot arch-support insole could resist depression of foot arch and provide adequate stability to help ankle motion. Thus the purpose of this study was to investigate the efficacy of arch-support design insoles on balance and gait plantar pressure in pregnant women during third trimester. Forty women in third trimester of pregnancy with flatfoot were recruited in this study. They were randomly assigned to arch-support group (experimental group) and normal design group (control group). Both groups were accepted collection of demographic data, static balance test, Times Up and Go test, plantar pressure test in walking and pain scale questionnaire. All tests included non-insole and wearing insole situation. The measured data analyzed by two-way mixed Analysis of variance. The SPSS 24.0 was used for statistical analysis and p value of 0.05 was considered to be significant. Result showed the experiment group had significantly lower COP excursion in M-L direction when eye-closed (p=0.009), plantar pressure in first toe (p=0.005) and medial side of middle foot (p=0.041) between pre-test and post-test. The low back pain scale was significantly decreased in experiment group (p=0.041).Control group had no any difference between pre-test and post-test. The women in Third Trimester of Pregnancy with arch-support insoles could help static balance in the darkness, decrease abnormal plantar pressure and reduce low back pain.

Background and purpose: Flexible flatfoot is commonly observed in young children. It is a condition when the medial longitudinal arch of the foot collapses in weight bearing and restores after removing the body weight. The condition is made worse by excessive loose soft tissue in the foot and is linked to various lower extremity injuries, such as patellofemoral pain syndrome, medial tibial stress syndrome and plantar fasciitis. Subjects with flexible flatfoot are usually prescribed exercises for strengthening selected lower limb muscles in order to reduce the risk of getting injury. However, the influence of lower limb muscles, especially the foot intrinsics, on the foot arch support is still unclear. Besides, differences of the center of pressure (COP) excursion between subjects with normal arch and flexible flatfoot were found in the past studies. However, it is unclear if the difference in COP excursion is associated with differential activation of selected lower extremity muscles. The purposes of our study are: (1) to investigate the function of selected lower limb muscles in arch support, and (2) to explore the association between the muscle activation of selected muscles and the displacement of COP during walking. Methods: Twenty flexible-flatfooted subjects and fifteen normal-arched subjects were recruited. The arch height, range of motion of ankle and foot, muscle strength of selected lower extremity muscles were measured in both groups. Then we collected activation of tibialis anterior, preoneus longus and hallucis abductor with surface electromyography and recorded the path of COP while the subjects were walking on a pressure mat system. Statistical Analysis: Independent t test was used to analyze group differences in the ROM and muscle strength. Analysis of variance with repeated measures was used to analyze the differences between the two groups in muscle activation of each period of the stance phase. Then we calculated Pearson's correlation coefficient to estimate the association between muscle strength, COP displacement, muscle activation and the severity of flatfoot. Results: Subjects with flexible flatfoot is stronger in hallucal abductor/flexor groups than the normal-arched subjects. The muscle activation of abductor hallucis in the terminal stance is significantly higher in subjects with flatfoot. The mediolateral displacement of COP during walking is smaller in flatfooted subjects. There are positive correlations between the severity of flatfoot, strength of hallucal abductor/flexor groups and the activation of abductor hallucis during terminal stance (r=0.43-0.49). There is a weak negative correlation between the mediolateral displacement of COP and severity of flatfoot (r=-0.35). Conclusions: The posture of foot might influence selected muscle activation and COP excursion during gait. The hallucal abductor/flexor groups are stronger and the abductor hallucis muscle is more active in the terminal stance in our subjects with mild flexible flatfoot; this may be explained by overloading the muscle to aid push-off and propulsion of the body weight in these individuals. Additionally, narrower mediolateral COP span, which was weakly negatively correlated to the activation of abductor hallucis, was found in subjects with flatfoot during walking. Clinical Relevance: Abductor hallucis is assicated with COP excursion during gait, and may be highly recruited in subjects with mild flexible flatfoot. These subjects may benefit from training programs to reduce the risk of fatiguing this muscle.

Повний текст джерелаAboriginal and Torres Strait Islander Peoples suffer from high rates of chronic disease, including peripheral vascular disease, and diabetes, and the associated increases in morbidity and mortality has an enormous impact on both life span and quality of life. Foot health in Aboriginal and Torres Strait Islander Peoples is widely accepted to be poor. In those with diabetes there is a high incidence of neuropathy, foot ulceration, infection and amputation. However, there is little available literature investigating the nature and extent of foot disease in Aboriginal and Torres Strait Islander Peoples, particularly in those with diabetes, or how this can be effectively managed. Anecdotal evidence suggests high rates of restricted ankle joint dorsiflexion (ankle equinus) may exist in the Aboriginal and Torres Strait Islander population and this may be a significant contributing factor to the development of diabetic foot complications including pressure ulcerations. This research addresses the hypotheses that: ; Chronic disease and lifestyle factors significantly contribute to foot complications in Aboriginal and Torres Strait Islander Peoples. ; Culturally appropriate inclusive health promotion can improve foot health outcomes and support healthy lifestyle choices in an Aboriginal and Torres Strait Islander community. ; High prevalence of ankle equinus significantly contributes to elevated plantar pressures in Aboriginal and Torres Strait Islander Peoples with and without diabetes, which may be a significant factor contributing to poor foot health. Firstly, a literature review was conducted to establish current risk factors and risk markers for poor foot health in Aboriginal and Torres Strait Islander Peoples. Little data were found relating specifically to Aboriginal foot health, however high prevalence of chronic disease associated with foot complications including diabetes, neuropathy and peripheral vascular disease were evident. Lifestyle factors associated with increased risk of chronic disease, including smoking and obesity were also found to be highly prevalent, particularly in women. No literature investigating the role of lower limb structure or biomechanical function in development of foot complications was found. Secondly, a review of the literature to determine a reliable method of measuring ankle joint range of motion was conducted. This review showed significant inconsistency in the literature in relation to the definition and diagnosis of ankle equinus, and a lack of standardised method for clinical assessment. Based on these findings a device for accurately measuring ankle equinus was developed, (the Charles device) which was established to have excellent inter- and intra-tester reliability. Thirdly, a culturally appropriate health promotion program for improving foot health, reducing injury and increasing healthy lifestyle choices was developed for the local Worimi Aboriginal community in Forster/Tuncurry, New South Wales. Evaluation of this program demonstrated that it was effective in improving healthy lifestyle knowledge, behaviours and reducing risk of lower limb injury. These findings suggest appropriate health promotion may be successful in reducing risk of foot complications in Aboriginal and Torres Strait Islander People. Subsequently two cross-sectional cohort studies, one in Aboriginal and Torres Strait Islander People with diabetes and one in those without diabetes, were undertaken to test the hypothesis that restricted ankle joint dorsiflexion increases plantar pressures under the forefoot. High prevalence of isolated gastrocnemius equinus was found in both cohorts. Reducing ankle joint range of dorsiflexion was found to be significantly associated with higher peak pressures under the forefoot, and to be an independent predictor of increasing pressure-time integral under the forefoot in both populations. These results, limited by cross-sectional design, suggest ankle equinus may play a key role in the development of pressure-related forefoot complications in Aboriginal and Torres Strait Islander Peoples. Finally, as an appendix to this thesis, visual assessment of Aboriginal skeletal remains of the foot, of a small number of Kaurna People and 21,000 years old footprints of the Paakantji, Ngiyampaa and the Mutthi Mutthi Aboriginal People in Lake Mungo was undertaken. These were examined for arch height, indications of biomechanical characteristics of the foot and ankle and overt osseous pathology. Many of the ancient footprint showed signs of a high arch foot type similar to modern day Aboriginal footprints. In addition, bony spurring on the calcanei on a number of specimens was consistent with possible restriction in ankle dorsiflexion, suggesting ankle equinus may be an evolutionary trait in this population (Appendix 7).

This paper extends Hung and Chen's (1990) two dimensional numerical model to establish a three dimensional numerical model and discusses the hydrodynamic pressure on rigid arch dam faces during earthquakes. The nonlinear effects of free surface varitation and convective acceleration are included in the analysis. Different kinds of dam-reservoir systems are studied here and their corresponding geometric effects on hydrodynamic pressures are also discussed. Besides, the relationship between the linear hydrodynamic force coefficients and the intensity of the ground acceleration are studied and a simple empirical formula can be given.
