An investigation of the clinical assessment of joint position sense

Stillman, Barry Charles Unknown Date (has links) (PDF)
The assessment of proprioception in contemporary clinical practice usually involves having the patients with eyes closed attempt to identify passively held test positions using verbal descriptions or limb matching responses. It is equally common for the examiner to estimate the accuracy of these responses without the aid of a measuring instrument. Since these uninstrumented assessments are unlikely to allow adequate identification or quantification of a patient’s proprioceptive deficits, the aim of this study was to develop and validate an improved method for the clinical assessment of joint position sense. The two main types of assessment investigated were: (1) replication of joint positions using limb matching responses, during which the test and response positions were measured using computer-aided or manual digitisation of videotape images, and (2) joint position sense assessments where rating scales were used to define either the test or response positions.

Sledování svalové aktivity při chůzi u pacientů s valgózním postavením kolenních kloubů / Measurement of muscle activity during gait at patients with knock knees

Krist, Lukáš January 2013 (has links)
Title: Measurement of muscle activity during gait at patients with knock knees Objective: The aim of this study was to compare muscle activation between two groups of volunteers with and without knock-knees during level ground and incline walking on treadmill by surface electromyography. Muscles were measured on both legs, specificly tibialis anterior muscle, gastrocnemius lateralis muscle, vastus medialis muscle, adductor magnus muscle, semimembranosus muscle and tensor fasciae latae muscle. The goal of this experiment was to discover which muscles are more or less aktive according to the other group of participants. Then based on the conclusion could be possible to affect these changes by physiotherapy in future. Methods: The surface electromyography was used for measurement muscle activation. There were 12 volunteers, 9 women and 3 men, participate on this study in age from 21 to 27. Intermalleolar distance was used as a screening investigation for sorting into two groups whether the knock-knees are present or not. Result: There were different muscle activation between both groupes. Some muscles had increased activation others had lowest activation. However, this increase can be considered as statistically significant only in case of averrage amplitude muscle activity during midstance of step by...

Haunted dwellings, haunted beings : the image of house and home in Allende, MacDonald, and Morrison

Parker, Deonne January 2002 (has links)
This study examines the image of house and home as the reification of our domains as living, dwelling, housed beings in three novels: Isabel Allende's The House of the Spirits; Anne-Marie MacDonald's Fall On Your Knees; and Toni Morrison's Beloved. Being human, we form through perception, build through forming, dwell in building, and perceive through dwelling. Through close reading and analysis, this thesis examines questions of: If we are how we dwell, then what happens when the structures and the spaces of our dwellings become haunted? What happens when "home" becomes a facade that suspends necessary elements of dwelling? This study projects that if we are how we dwell, the very nature of our being entails a constant questioning of what it is we allow a presence to in our how we form, build, dwell, and perceive within both tangible and intangible realms and the influential perspicacity literature bears within this process.

Regions in time : Gail Anderson-Dargatz’s The cure for death by lightning and Ann-Marie Macdonald’s Fall on your knees

Lewis, Tanya 05 1900 (has links)
This thesis examines the methods through which Gail Anderson-Dargatz and Ann-Marie MacDonald construct region in their novels The Cure for Death by Lightning and Fall on Your Knees. These texts, like all successful regional novels, describe more than geography. Their regions are also functions of time. I introduce the term "temporal region" to describe the spaces created by this interdependence of time and place. I then focus upon the specifics of descriptive and narrative approach that lead to the convincing portrayal of the Shuswap and Cape Breton Island in the texts. Anderson-Dargatz and MacDonald direct attention to the foddways of their regions, expressing the connection between consumption choices and a society's historical and physical location. The authors also articulate their regions by highlighting cultural diversity in the areas they describe. In this way they deny the social homogeneity more sentimental regional texts often rely upon. Finally, the novelists use an appropriately Canadian method of regional opposition to define their temporal regions according to that which they are not ~ they are not American, glamorous, or urban. They therefore must be Canadian, quotidian, and rural.

No. of bitstreams: 1 texto completo.pdf: 877851 bytes, checksum: e19d9e07d366a220755f330c28b830fe (MD5) Previous issue date: 2005-04-15 / The aim of this study was to evaluate the clinical and morphophisiological aspects of the rat knee articulation after immobilization and remobilization with free activity and swimming. Thirty four adult male rats (Wistar) were randomly allocated into one of four groups: without immobilization, (G1, n = 4), with immobilization (G2, n = 10), immobilization and remobilization with free activity (G3, n = 10), and immobilization and remobilization with free activity and swimming (G4, n = 10). Animals had the right knee joint immobilized for 45 days. Animals from G2 were killed after this immobilization period and so were those from G1. After the immobilization period animals from G3 were allowed to move freely in their cages and those from G4 add to that were submitted to a swimming program for 5 weeks and were than all killed. During the remobilization period animals from G3 and G4 had their march clinically evaluated. After being killed the articular amplitude of the right knee was assessed in all animals and histological slices from the articular capsule, cartilage and subchondral bone were obtained. The results showed that animals from G4 exhibited a better march evolution on the first five days period as compared to those from G3. After such period march evolution were similar in both G3 and G4. Animals from G2 displayed rigid joint while in those from G3 and G4 the articular movement was close to normal. The histological analysis pointed out that immobilization led to increase in articular capsule thickness evidenced by the presence of fibrous connective tissue replacing adipose tissue in G2, but proportionally less in G3 and G4. By the analysis of the articular cartilage and subchondral bone it was observed that immobilization determined loss of proteoglycans from the cartilaginous matrix, increase in the number of regularly arranged condrocytes, increase in calcified cartilage thickness, irregularity in the articular surface, proliferation of connective tissue in the intraarticular space and increase in subchondral bone thickness. A animals from G3 displayed a greater number of alterations in both articular cartilage and subchondral bone, as compared to those from G4. It was concluded that: immobilization degenerated synovial cells indicating decreased synovial fluid production and reduced nutritional supplying to the cartilage; and both free cage activity and its association with swimming influenced positively the return of the capsule morphologic conditions to those before immobilization. / O objetivo do presente trabalho foi avaliar os aspectos clínicos e morfofisiológicos da articulação do joelho de ratos após imobilização prolongada e remobilização com atividade livre e natação. Trinta e quatro ratos adultos machos (Wistar) foram alocados aleatoriamente em um dos quatro grupos: sem imobilização (G1, n = 4), com imobilização (G2, n = 10), imobilização e remobilização com atividade livre (G3, n = 10), imobilização e remobilização com atividade livre e natação (G4, n = 10). Os animais tiveram o joelho direito imobilizado por 45 dias. Os animais do G2 foram sacrificados após o período de imobilização, juntamente com os animais do G1. Após o período de imobilização os animais do G3 movimentaram livremente em suas respectivas gaiolas e os animais do G4, além da movimentação na gaiola, foram submetidos a um programa de natação por 5 semanas, sendo todos sacrificados em seguida. Durante este período de remobilização os animais dos G3 e G4 foram submetidos a avaliação clínica da marcha. Após sacrifício a resistência à flexão articular do joelho direito de todos os animais foi avaliada e cortes histológicos da cápsula articular, cartilagem e osso subcondral foram obtidos. Os resultados mostraram que os animais do G4 apresentaram melhor evolução na marcha nos cinco primeiros dias, em relação àqueles do G3. Após este período a evolução na marcha foi similar nos G3 e G4. Animais do G2 apresentaram rigidez articular enquanto nos do G3 e G4 o movimento estava próximo ao normal. A análise histológica mostrou que a imobilização promoveu aumento da espessura da cápsula articular, evidenciada pela presença do tecido conjuntivo fibroso substituindo o tecido adiposo no G2, mas em menor proporção nos G3 e G4. Pela análise da cartilagem articular e osso subcondral pode-se observar que a imobilização determinou perda de proteoglicanos da matriz cartilaginosa, aumento do número de condrócitos dispostos de forma irregular, aumento da espessura da cartilagem calcificada, irregularidade da superfície articular, proliferação de tecido conjuntivo no espaço intra-articular e aumento da espessura do osso subcondral. Os animais do G3 apresentaram um maior número de alterações tanto na cartilagem articular como no osso subcondral, quando comparados com aqueles do G4. Concluiu-se que a imobilização degenerou as células sinoviais, indicando diminuição da produção de fluido sinovial e redução do suprimento nutricional à cartilagem; e que tanto a atividade livre na gaiola quanto sua associação com a natação influenciaram positivamente o retorno das condições morfológicas da cápsula, anteriores à imobilização.

Modélisation et optimisation de la marche d'un robot bipède avec genoux anthropomorphiques / Modeling and Optimization of the Gait of a Biped Robot with Anthropomorphic Knees

Hobon, Mathieu 12 December 2012 (has links)
La conception des robots humanoïdes est un défi depuis plusieurs années. Les articulations de l'être humain de par leur complexité cinématique créent des mouvements difficilement reproductibles par un mécanisme. Le genou humain permet des mouvements composés de roulement et de glissement. La conception de nouvelles articulations bio-inspirées est un enjeu pour recréer avec un robot une marche anthropomorphe. Une analyse de la cinématique des genoux a été effectuée et nous proposons une solution mécanique pour reproduire cette cinématique de genoux. L'idée est de recréer un genou avec un contact roulant entre le fémur et le tibia. Les modèles géométriques, cinématiques et dynamiques et un modèle d'impact sont développés pour un robot bipède muni de ce genou à contacts roulants. L'allure de marche est étudiée sous forme d'un problème d'optimisation paramétrique sous contraintes. Les trajectoires de marche sont approximées par des fonctions mathématiques pour deux allures de marche : une allure de simple support avec impacts et une allure de double support suivi d'un simple support puis d'un impact. Des critères énergétiques permettent de comparer le robot muni du mécanisme de genoux roulants à un robot muni de genoux à liaison rotoïde. Les résultats des optimisations montrent que le genou roulant apporte une diminution du critère sthénique. L'optimisation énergétique montre que les couples articulaires sont plus faibles sur les hanches ce qui engendre une diminution de la masse des actionneurs du robot. Enfin, un gain d'énergie est possible en associant des systèmes à ressorts en parallèle sur les articulations du robot. / The design of humanoids robot has been a tricky challenge for several years. Due to the kinematic complexity of human joints, their movements are notoriously difficult to be reproduced by a mechanism. The human knees allow movements including rolling and sliding, and therefore the design of new bio-inspired robots is of utmost importance for the reproduction of anthropomorphic walking in a robot. In this thesis, the kinematic characteristics of knees were analyzed and a mechanical solution reproducing them is proposed. The geometrical, kinematic and dynamic models are created together with an impact model for a piped robot with the knees proposed. The walking is studied as of a problem of parametric optimization under constraints. The trajectories of walking are simulated approximately by mathematical functions for two gaits: one of a single support with impacts and one of double supports followed by a simple support and then an impact. Energy criteria allow comparing the robot provided with the mechanism of rolling knees and a robot provided with revolute knees connection. The results of the optimizations show that the rolling knee brings a decrease of the sthenic criterion. The energy optimization shows that the articular couples are weaker on hips what engenders a decrease of the mass of the actuators of the robot. Finally, energy gains are possible by associating spring systems.
