A instabilidade articular é responsável pelo desenvolvimento de lesões degenerativas incapacitantes que comprometem o desempenho funcional. Compreender os processos desenvolvidos para estabilização dinâmica articular é um desafio para pesquisadores das mais diversas áreas. O presente estudo propõe o uso da abordagem Biomecânica para reconhecer os mecanismos relacionadas ao processo de estabilização dinâmica articular, por meio de três diferentes condições experimentais. No experimento 1 foi analisada a Força de Reação do Solo (FRS) e a cinemática 3-D no andar, correr e saltar de portadores (n=10) e não portadores de instabilidade crônica (n=10) do tornozelo. No experimento 2 foi analisada a Eletromiografia dos músculos tibial anterior, fibular longo, fibular curto e gastrocnêmio lateral de portadores (n=14) e não portadores de instabilidade crônica (n=14) do tornozelo antes e após um protocolo de indução à fadiga muscular. No experimento 3 (n=20) foi analisado o efeito do exercício de alongamento muscular estático passivo dos músculos fibular longo e fibular curto na simulação da entorse do tornozelo. Nos protocolos de locomoção foram encontrados no lado acometido picos tardios e aumento dos Impulsos da FRS. No início da fase de apoio o tornozelo instável no andar aumentou a dorsiflexão, no correr aumentou a eversão e no saltar diminuiu a inversão e aumentou a dorsiflexão. Tais estratégias representam a tentativa de melhorar a estabilidade dinâmica articular. No entanto, a variação angular da articulação no plano sagital e frontal aumentaram, sugerindo que há mais amplitude de movimento no tornozelo acometido e maior estresse sobre os estabilizadores passivos locais. Em condições de fadiga muscular, após simulação da entorse, indivíduos com articulações saudáveis aumentam a rigidez articular e a intensidade de contração dos eversores do tornozelo, antecipadamente a perturbação, diferente de portadores de instabilidade crônica. A execução do exercício de alongamento dos músculos fibulares longo e curto, seguido da simulação da entorse, gerou o retardo da resposta motora e diminuição da intensidade de ativação. Desta forma, as estratégias desenvolvidas por portadores de instabilidade crônica podem ser relacionadas à causa e/ou consequência do quadro, a fadiga muscular altera o desenvolvimento de estratégias de proteção e o exercício de alongamento pode prejudicar a estabilização dinâmica articular / Joint instability is associated with degenerating injuries that lead to functional incapacitation. Knowing the process involved in joint dynamic stabilization is a challenge to researchers in many fields. This study proposes the use of a biomechanical approach to recognize the mechanisms involved in joint stabilization through three different experimental conditions. The first experiment analyzed the Ground Reaction Force (GRF) and the 3D kinematics in participants with (n=10) and without (n=10) chronic ankle instability during walking, running and jumping. The second experiment analyzed the Electromyography signal of tibialis anterior, peroneus longus, peroneus brevis e gastrocnemius lateralis in participants with (n=14) and without (n=14) chronic ankle instability before and after a muscle fatigue protocol. The third experiment (n=20) analyzed the effect of static passive stretching of peroneus longus and peroneus brevis muscles on the ankle sprain simulation. During the locomotion protocols the injured side showed late peaks and an increase of the GRF impulses. The instable ankle showed an increase of dorsiflexion during the initial phase of gait and an increase of eversion during running. The instable ankle also showed a decrease of inversion and an increase of dorsiflexion during jumping. These strategies represent an attempt to improve the joint dynamic stability. There was an increase in sagittal and frontal angular displacement, suggesting more range of motion as well as more stress in the passive structures that are responsible for stabilization in the injured ankle. During muscular fatigue, after an ankle sprain simulation, subjects with healthy joints increase the joint stiffness and the intensity of the ankle eversion muscles activation, before the intervention, differently from subjects with chronic instability. The peroneus longus and brevis stretching exercise followed by the ankle sprain simulation caused a delay on the motor response and a decrease in the activation intensity. The strategies developed by the subjects with chronic instability can be related to the cause and/or the consequence of the dysfunction. The muscular fatigue changes the development of strategies of protection and the stretching exercise can weaken the dynamic stability of the joint

Title: Use of compensatory exercises for footballers in the youth sports center Objectives: The aim of the work is to identify the most common muscle imbalances and to create a compensation program for football players in the category of younger students U12 and U13 in the youth sports center. Methods: The research was based on the diagnosis of players using test exercises, which focused on the occurrence of muscle imbalances and erroneous movement stereotypes according to Bursová (2005), Hošková & Matoušová (2007) and Bursová et al. (2003). Detection was provided by selected functional muscle tests, which were applied in the input and output measurements. Correct performance of the exercise was evaluated as number 1. Incorrect performance was evaluated as number 2. After the initial measurement and evaluation of the degree of muscle imbalances, a compensation program was designed, whose primary task was to eliminate or alleviate muscle imbalances of individual players. The final measurement was used to verify the effectiveness of the compiled compensation program. A one - sample nonparametric Wilcoxon test was used in the work, the task of which was to confirm the validity of the used tests. Results: Due to the fact that the results of selected probands improved in most of the test exercises...

Objetivo: Exercícios de mobilização são aplicados em pacientes com Espondilite Anquilosante (EA) para preservar e restaurar a mobilidade axial, no entanto, não há descrição na literatura, de um programa específico de reabilitação compreendendo apenas exercícios de mobilização com e sem a associação de exercícios com resistência elástica em pacientes com EA. Assim, foram avaliados os efeitos de dois programas de exercícios quanto a mobilidade, capacidade funcional, qualidade de vida e atividade de doença em pacientes com EA. Métodos: Cinquenta e cinco pacientes com EA, sedentários, com Índice Bath de atividade de doença da Espondilite Anquilosante (BASDAI) < 4 foram incluídos no estudo. Os pacientes com EA foram alocados ao acaso em três grupos, um grupo foi prescrito exercícios de mobilização (M), um com o programa de mobilização mais exercícios de resistência elástica (M+R) e um grupo controle sem exercícios (C). As sessões de exercícios foram realizadas em grupos, duas vezes por semana, por 16 semanas, e todas as sessões foram supervisionadas. Os grupos M e M+R realizavam 30 minutos de alongamentos e exercícios de mobilidade para coluna, membros superiores e inferiores. Depois do programa de mobilização, apenas o grupo M+R realizava mais 30 minutos de exercícios com resistência elástica. A mobilidade, qualidade de vida, atividade de doença e parâmetros de atividade funcional foram avaliados no início do programa e depois de 16 semanas por um avaliador cego. Resultados: No início do estudo, a média de idade dos pacientes (DP) era 48,2 anos ( ± 11,7); tempo de doença 18,4( ± 9,9) anos; BASDAI 2,2( ± 1,2); escore global Bath de espondilite anquilosante (BAS-g) de 4,2( ± 2,3) Índice funcional Bath (BASFI) de 3,6( ± 2,4) e Índice de mobilidade Bath (BASMI) de 4,6( ± 2,1). Comparando valores iniciais e após 16 semanas o grupo M mostrou uma melhora significante no Índice BASMI e o grupo M+R apresentou uma melhora significante no BASMI e na expansibilidade torácica. BAS-g, BASDAI e BASMI foram significantemente piores no grupo C. Não houve diferença significante entre os grupos M e M+R, mas foi encontrada diferença estatisticamente significante entre os grupos C e M+R nos índices BASDAI, ASDAS e BASFI a favor do grupo M+R. Conclusão: Os programas de exercícios terapêuticos foram seguros e efetivos. O programa de mobilização promoveu benefícios apenas nos parâmetros de mobilidade articular. Os pacientes que realizaram programa de exercícios com resistência elástica além de apresentarem melhora na mobilidade articular, apresentaram melhora da atividade de doença e função quando comparado aos controles no fim do tratamento / Objective: Mobility exercises are used in Ankylosing Spondylitis (AS) patients to preserve and restore axial mobility, but there are no data regarding a specific rehabilitation program that includes mobility alone and its association with elastic resistance exercises in AS patients with stable disease activity. So, we assessed the effects of two exercise programs in terms of mobility, functional capacity, quality of life and disease activity in AS patients. Methods: Fifty-five sedentary AS patients with a Bath Ankylosing Spondylitis Activity Index (BASDAI) <4 were included. The AS patients were randomly assigned into three groups, to receive a mobility exercise program (M), or mobility plus elastic resistance exercise program (M+R) or no exercise (C). The exercises group sessions were conducted twice per week for 16 weeks. This supervised program comprised 30 minutes of outdoor stretching and mobility exercises for the spine and limbs (M). After the mobility program, M+R group carry out more 30 minutes of elastic resistance exercises. The mobility, disease activity and functional parameters were evaluated at baseline and after 16 weeks, with the evaluator blinded to the treatment group. Results: At study entry, the patients had a mean (SD) age of 48,2 years ( ± 11,7), disease duration of 18,4( ± 9,9) years, BASDAI 2,2( ± 1,2), Bath AS Global score (BAS-g) 4,2( ± 2,3) Bath AS functional Index (BASFI) of 3,6( ± 2,4) and Bath AS Metrology Index (BASMI) of 4,6( ± 2,1). Comparing the baseline to 16 weeks, group M showed a significant improvement in BASMI and M+R group showed significant improvement in BASMI and chest expansion. BAS-g, BASDAI and BASMI was significantly worst in C group. No significant differences between M+R group and M group were perceived but there were significant differences in BASDAI, ASDAS and BASFI scores between C group and M+R group in favor of M+R group. Conclusion: Therapeutic exercises programs were effective and safe. The mobility exercises program promoted benefits only in joint mobility parameters. The exercise program with elastic resistance besides those benefits for joint mobility, also improved function and disease activity comparing to controls at the end of the program

Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, 2014. / Background: Myofascial Pain and Dysfunction (MPD) is a diagnosis commonly encountered by practitioners, hence, there are several treatment approaches employed by various practicing physicians. Practitioners are required to perform evidence-based protocols on patients; however, such intervention becomes increasingly difficult with the increasing volume of evidence available with regards to treatment of MPD. A systematic review provides a well-structured, critical analysis of the available protocols, and as such, provides practitioners with an evidence-based summary of the available modalities and the effectiveness of these modalities. Thus, the aim of the study was to systematically review and evaluate the literature to determine the effects of various non-invasive modalities on MPD. Objectives: Studies investigating various non-invasive modalities were identified, evaluated against the inclusion criteria and then reviewed against PEDro criteria to present current available evidence regarding their effectiveness as a source of treatment for MPD. Methods: A literature search was conducted, based on key terms including: active and latent myofascial trigger points, manual therapy, manipulation, acupressure, massage, muscle stretching, ultrasound, transcutaneous electric nerve stimulation, electric stimulation therapy, magnetic field therapy, and exercise therapy. Databases searched were: PubMed, EBSCOhost, Medline, CINAL, Proquest, Health Source, Sport Discus, Science Direct, Springer Link, Google Scholar and Summons. The articles were screened according to inclusion and exclusion criteria, after which a secondary hand and reference searches were performed. Thereafter, the articles were reviewed by four independent reviewers and the researcher. The PEDro Scale was used to determine methodological rigor of the included studies. The results were then analysed and ranked. Results: Following the screening process during data collection for this study, a total of 25 studies were identified and included. The review and ranking of these studies revealed a moderate level of evidence present for the effectiveness of Topical Agents. A limited level of evidence was noted for TENS, Ischemic Compression, Ultrasound, Laser and Other Modalities. Approximately 25% of the reviewed studies involved combination therapies; hence their outcomes cannot be applied to the effectiveness of individual modalities. Conclusion: Upon comparison of the quality of evidence available for the various types of modalities present for the treatment of MPD, it was noted that Topical Agents were supported by a stronger level of evidence than TENS, Ischeamic Compression, Ultrasound, Laser and Other Modalities. However, due to a lack of strong overall evidence for any of these modalities it has been concluded that more research is required to establish which modality is in fact the most effective.
