Introduction. Rheumatoid arthritis is a disease that causes the dislocation of joints. Foot deformity and deformity of foot fingers is brought about by inflammatory processes in the joints and due to the changed pressure of body weight on the feet. The computerized method of foot-barography allows one to estimate in what way the pressure of body weight on the feet distributes itself during the process of walking and in the standing posture. This method also allows one to judge about foot deformity as well as the condition of foot joints, ligaments and muscles of the patient. The aim of the research was to study the efficiency of applying the computerized method of foot-barography in the treatment of foot joints damaged by rheumatoid arthritis. Subjects and Methods. The research was carried out at the Polyclinic of the Joint-Stock Company „Ortopedijos technika“ (Orthopedic Technology) in Kaunas. The subjects were 19 females and 3 males suffering from chronic rheumatoid arthritis. The patients were divided into 2 groups: 1) the experimental group, i.e. patients to whom kinesitherapy was applied, and 2) the control group, i.e. patients to whom kinesitherapy was not applied. The feet of the patients have been studied applying the computerized method of foot-barography. The distribution of the pressure of body weight on definite points (5, 7, 10, 13, 17, 18, 19, 20) of the foot as well as on the fingers and hell of the foot has been analysed. Conclusions. As a result of the... [to full text]

O padrão mastigatório ideal é o bilateral alternado, entretanto, alguns indivíduos apresentam um lado preferencial de mastigação. Objetivo: Desenvolver um método computadorizado para avaliar o padrão de deslocamento lateral da mandíbula durante a função mastigatória. Metodologia: Foram avaliados 44 vídeos de processos mastigatórios através de algoritmo desenvolvido, onde os indivíduos foram orientados a realizar um padrão específico de mastigação: somente do lado esquerdo ou direito (grupo 1), alternando cinco mordidas de um lado e duas do lado oposto (grupo 2), alternando 3 mordidas de cada lado (grupo 3). O método computacional identificou, quadro a quadro, o deslocamento lateral do mento e determinou a amplitude e a porcentagem de deslocamentos laterais da mandíbula para cada lado. Resultados: Os grupos 1 e 2 exibiram valores significativamente maiores de número de ciclos do lado de mastigação em relação ao lado oposto (75,41% e 64,82%, respectivamente) e não houve diferença entre os lados direito (46,73%) e esquerdo (53,27%) no grupo 3. A amplitude dos ciclos exibiu o mesmo comportamento. Nos grupos 1 e 2 o método identificou o lado de preferência de mastigação, entretanto a porcentagem de ciclos identificados no lado de mastigação foi significativamente menor do que a porcentagem de ciclos solicitada (p<0,001). Conclusão: A utilização da filmagem do processo mastigatório associada ao método computadorizado proposto mostrou-se eficaz em identificar o padrão mastigatório bilateral e em reconhecer a existência da preferência em utilizar um dos lados durante os ciclos mastigatórios. / Introduction: Mastication is one of the main functions of the stomatognathic system, and it is a physiological and complex action. The ideal masticatory pattern is the bilateral alternated, however, some people have a preferred side of mastication. Objective: To develop a computerized method to assess the mandibular lateral deviation pattern during mastication. Method: 44 videos of masticatory processes were analysed using the algorithm developed. The individuals were instructed to perform a specific pattern of mastication: only on the left or the right side (group 1), alternating five bites on one side and two on the opposite side ( group 2), alternating 3 bites on each side (group 3). The computerized method identified, frame by frame, the lateral displacement of the chin and determined the amplitude and the percentage of mandibular lateral deviation to each side. Results: The groups 1 and 2 showed significantly higher number of cycles on the side of chewing compared to the opposite side (75.41% and 64.82%, respectively) and there was no difference between the right side (46.73%) and left side (53.27%) in group 3. The amplitude of cycles showed similar results. In groups 1 and 2, the method identified the preferred chewing side, however, the percentage of the identified cycles in the chewing side was significantly lower than the percentage of cycles required (p <0.001). Conclusion: The use of filming of the masticatory process associated with the proposed computerized method was effective in identifying the bilateral masticatory pattern and recognizing the existence of preference to use one of the sides during the masticatory cycles.
