M.Tech. / The aim of this single blinded clinical trial was to determine the most effective myofascial dry needle insertion time for the relief of active trigger points in the trapezius muscle. It was hypothesised that at least one of the three time frames chosen in this study; namely 30 seconds, 1.5 minutes and until the patients pain referral ceased, would prove to be the most effective time to increase the patients pressure tolerance and decrease their subjective perception of pain. Thirty six patients who presented with bilateral active trapezius trigger points and who fell into the inclusion-exclusion criteria of this study were recruited from in and around the University of Johannesburg. Once selected for the study the patients, whose ages ranged from 18 to 40 years of age, where randomly divided into two groups of eighteen. In this study each patient served as their own control. The left and right sides where randomly assigned to either being the control side (needled for 30 seconds) or the experimental side (needled for 1.5 minutes or until the pain referral stopped). Because of this further randomisation, the two groups of eighteen were divided in to four groups of nine: Group one: Right side was the control and the left side was needled for 1.5 minutes. Group two: Right side was the control and the left side was needled until the patients pain referral ceased. Group three: Left side was the control and the right side was needled for 1.5 minutes. Group four: left side was the control and the right side was needled until the patients pain referral ceased. The patients received a once off treatment, where they were needled bilaterally with the control side being needled for 30 seconds and the experimental side being needled for either 1.5 minutes or until the pain referral stopped. The patients were required to come back for a follow-up assessment two days later. Objective measurements were obtained by using the algometer, which measured the pressure threshold of the left and right trapezius before the needling treatment, immediately after the treatment and on the two day follow-up visit. Three reading were taken at each time interval. vi Subjective measurements were obtained by using the visual analogue scale (VAS) and a subjective pain and discomfort questionnaire which patients were required to complete before the treatment, immediately after the treatment and at the two day follow-up visit. The data was statistically analysed using the Kruskal Wallis Test and the Wilcoxon Signed Ranks Test. For the inter-group analysis for average algometer readings, due to the small sample size, only group one and group four showed statistically significant changes in the average algometer readings over time. In group one the control side showed the greatest change, and in group four both the control and the experimental (which was needled until the pain referral ceased) showed a change in average algometer readings. Although the statistical evidence is inconsistent, there was a general trend of improvement seen over all four groups in terms of the average algometer readings over time. Subjectively it was seen that all four groups had a statistical decrease in the patients perceived pain with the VAS, with group four showing the most significant change over the three time variables (pre to post, post to follow-up and pre to follow-up). Group one had a statistical change from the pre reading to the post reading. Group two had a statistical change from the pre reading to the follow-up reading. Group three had a statistical change from the pre reading to the post reading. It was noted from the subjective pain and discomfort questionnaire that the patients who where needled for 30 seconds experienced a persistent stiffness and pain (although less than what they experienced before) immediately after the treatment and on their two day follow-up visit. This contrasted with the patients who were needled for 1.5 minutes and until the pain referral ceased (which averaged at 1 minute for group two and four) who experienced more relief immediately after the treatment and on the two day follow-up visit. From these results it is seen that even though objectively both the 30 second time frame and the longer time frame proved to increase pressure threshold, subjectively the patients who were needled for the longer time felt more relief than those who were needled for the shorter time frame.

L’obésité et le syndrome d’apnée-hypopnée obstructive du sommeil sont des maladies chroniques sociétales qui entraînent chacune leur lot de complications. Parmi les complications rapportées, plusieurs peuvent être améliorées en adhérant à un programme d’activité physique adapté. Plus précisément, la faible capacité à l’effort et l’essoufflement marqué peuvent bénéficier d’un programme d’activité physique. Le syndrome d’apnée-hypopnée obstructive du sommeil et l’obésité ont été liés à un essoufflement important à l’effort et à une fatigabilité des muscles respiratoires et locomoteurs accrue. Certaines évidences suggèrent qu’un soulagement du travail des muscles respiratoires grâce à la ventilation non-invasive lors de l’effort peut améliorer la tolérance à l’effort de façon aiguë. De plus, d’autres évidences ont montré que le réentraînement des muscles respiratoires peut aussi améliorer la tolérance à l’effort. Le présent mémoire s’est établi dans ce contexte. On a cherché à savoir si une des modalités d’entrainement suivantes, un entraînement des muscles respiratoires combiné à un entraînement cardiovasculaire, un entraînement cardiovasculaire avec application de ventilation ou un entraînement cardiovasculaire seul, était supérieure pour améliorer la capacité à l’exercice d’individus obèses souffrants d’un syndrome d’apnée-hypopnée obstructive du sommeil. / Obstructive sleep apnea-hypopnea syndrome and obesity are non-communicable diseases that lead to several complications. Many of those consequences, for example low cardiorespiratory fitness and marked breathlessness, can be improved by cardiovascular training. Obstructive sleep apnea-hypopnea syndrome and obesity have been associated with exertional dyspnea and with increased locomotor and respiratory muscle fatigue. Application of non-invasive ventilation is suggested to improve exercise tolerance in obesity while other studies suggest that respiratory muscles training also improve exercise tolerance. It is in this specific context that this thesis was written. We wanted to verify the impact on exercise capacity and tolerance of the following training modalities: cardiovascular training, cardiovascular training with non-invasive ventilation or cardiovascular training combined with a respiratory muscles training.

Ce projet de recherche consistait à évaluer la présence d'hyperréactivité bronchique et d'anomalies respiratoires durant le sommeil chez des patients avec une maladie coronarienne atherosclérotique établie. La première partie du projet portait sur la relation entre l'athérosclérose coronaire mesurée par échographie intravasculaire et la réactivité bronchique et/ou l'inflammation. Nous n'avons pas observé de relation entre le volume de la plaque d'athérosclérose coronaire et le degré de réactivité bronchique. La seconde partie de l'étude consistait à évaluer la relation entre l'athérosclérose coronaire mesurée par échographie intravasculaire et les anomalies respiratoires durant le sommeil quantifiées par enregistrement polysomnographique. Nous avons démontré qu'il existe une relation entre l'index d'apnée/hypopnée obstructif et le volume de la plaque d'athérosclérose coronaire. / This project aimed to evaluate the presence of airway hyperresponsiveness and sleep-related respiratory abnormalities among patients with established atherosclerotic coronary disease. The first part of the project studied the relationship between coronary atherosclerosis as measured by intravascular ultrasound, and airway hyperresponsiveness or inflammation. We observed no relationship between the degree of airway responsiveness and coronary artery plaque volume. In the second part of the study, we evaluated the relationship between the coronary atherosclerosis plaque, measured by intravascular ultrasound, and sleep respiratory abnormalities, quantified by polysomnographic recordings. We found a significant relationship between the obstructive apnea/hypopnea index and the coronary artery plaque volume.
