The purposes of this dissertation were to (1) test different gait paradigms for their sensitivity of identifying concussion symptoms and to (2) test how individual components of attention interact with gait performance. The long-term goal of this study is to establish more functional and succinct protocols for return-to-play decisions. Grade II (AAN guidelines) concussed individuals were recruited to participate in testing at 2, 6, 14, and 28 days post-injury. Gait and components of attention were analyzed during each session through a number of different paradigms. Control subjects were matched by stature, age, and athletic participation. The results indicate that the dynamic balance deficits following a concussion are immediately identified with an attention dividing gait task. Obstacle crossing identified more conservative adaptations 2 weeks after injury. A task combining the two did not clearly identify concussion deficits. Two components of attention showed promise as interacting with gait to cause balance deficits. The spatial orientation component showed an interaction with obstacle avoidance indicating that the same concussed individuals that had poor spatial orientation of attention also came closer to hitting the obstacle during crossings. An analysis of divided attention showed that concussed individuals performing poorly in one task also performed poorly in the other during a dual-task paradigm, but during any one particular trial there was a trade-off between task performances, which was not present in control individuals. The findings of this dissertation point to the use of a divided attention task to distinguish concussed individuals from healthy individuals immediately after a possible injurious event. How several different components of attention interact with gait performance is identified. Finally, if a concussion has occurred, an obstacle crossing task might be suitable for a long-term analysis of full recovery of balance control. Ultimately, it is my hope that the information provided here will lead to functionally relevant and clinically executable tests of concussed individuals before they are placed in harm's way due purely to an incomplete diagnosis of their injuries. / Adviser: Li-Shan Chou

Abnormal superior translation of the humeral head is believed to be one of the major causes of this pathology. The overall purpose of this study was to better understand glenohumeral kinematics in normal healthy individuals using fluoroscopy to help comprehend the mechanism of shoulder impingement. This research was divided into three sections: a validation study to measure humeral head translation, a comparison between dynamic and static arm elevation and lastly, humeral head translation after a suprascapular nerve block. In the first study, fluoroscopy was used to take images of human cadaver shoulders. Scapular orientation was manipulated in different positions while the humerus was at 90 degrees of elevation. Humeral head translation was measured using two methods and was compared to the known translation. Additionally, the accuracy of the contour registration method to measure 2-D scapular rotations was assessed. For the second study, subjects elevated their dominant arm while fluoroscopic images were taken. An edge detection software was utilized to digitize points on both the humeral head and glenoid. Humeral head translation and scapular upward rotation were measured using a contour registration method with respect to the glenoid during arm elevation. Five different arm elevation angles were investigated to measure differences in humeral head translation between trials. There was no difference found between humeral head translation and scapular upward rotation between static and dynamic shoulder elevation. For the third study, humeral head translation was measured before and after a suprascapular never block. The humeral head was superiorly located and the scapula was more upwardly rotated after the block. The differences were observed during mid range of motion. This result showed that there was a compensatory increase in both humeral head translation and scapular upward rotation due to the nerve block. These results suggest that increasing muscular strength and endurance of the supraspinatus and infraspinatus muscle could prevent any increased superior humeral head translation. This may be beneficial in preventing shoulder impingement or rotator cuff tear over time. This dissertation includes unpublished co-authored materials. / Committee in charge: Andrew Karduna, Chairperson, Human Physiology; Li-Shan Chou, Member, Human Physiology; Louis Osternig, Member, Human Physiology; Stephen Frost, Outside Member, Anthropology

Métodos: Foram avaliadas 20 crianças RBF, as quais foram submetidas a 15 sessões de BR, por meio do biofeedback pletsmovent (MICROHARD® V1.0), o qual proporciona o biofeedback dos movimentos tóracoabdominais. Perimetria torácica, espirometria e medidas das pressões respiratórias máximas estáticas foram realizadas antes e após a terapia. Questões respondidas pelos responsáveis foram utilizadas para avaliar os hábitos dos RBF. Os dados foram analisados por meio de teste t de Student para dados pareados e testes não paramétricos. Resultados: O uso do BR associado ao padrão quiet breathing não produziu alterações significativas na perimetria torácica e nos valores de volume expiratório forçado no primeiro segundo (VEF1), capacidade vital forçada (CVF), pico de fluxo expiratório (PFE), índice de Tiffeneau (IT) e na pressão expiratória máxima (PEmax). Entretanto, a pressão inspiratória máxima (PImax) apresentou diferença estatisticamente significativa (-53,6 ± 2,9 cmH2O vs. -65,0 ± 6,0 cmH2O; p < 0,05) e ocorreram mudanças significativas nos hábitos avaliados. Conclusão: Os resultados permitem concluir que o BR associado ao padrão quiet breathing melhora a força da musculatura inspiratória e hábitos em RBF, podendo ser, portanto, utilizado como uma das formas de terapia nestes indivíduos. / Objective: To evaluate the effects of the use of respiratory biofeedback (RB) associated with quiet breathing on the thoracic perimetry, pulmonary function, force of the respiratory muscles and the following habits of functional mouth breathing (FMB): vigil of open mouth, sleeps of open mouth, dribbles in the pillow, difficult wakening, snore and restless sleep. Methods: It had been evaluated 20 FMB children, which had been submitted to 15 sessions of RB, through biofeedback pletsmovent (MICROHARD® V1.0), which provides the biofeedback of the thoraco-abdominal movements. Thoracic perimetry, spirometry and measures of the maximum static respiratory pressures were determined before and after the therapy. Subjects answered by the responsible ware used to evaluate the habits of FMB. paired Student’s t test and nonparametric tests had been used for analysis of the data. Results: The use of the RB associated with quiet breathing didn’t produce significant alterations in the thoracic perimetry and in the values of forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), peak of expiratory flow (PEF), Tiffeneau indice (TI) and in the maximal expiratory pressure (PEmax). However, the maximal inspiratory pressure (PImax) presented significant statistic difference (-53.6 ± 2.9 cmH2O vs. -65.0 ± 6.0 cmH2O; p < 0.05) and happened significant changes in the evaluated habits. Conclusion: The results allow to conclude that the RB associated with quiet breathing improves the force of the inspiratory muscles and habits in FMB, therefore, it can be used as form of therapy in these individuals. / TEDE / BV UNIFESP: Teses e dissertações

However, the procedures involved in the technique may vary, particularly in terms of water temperature and immersion time, and the most effective approach remains unclear. Purpose: To determine the efficacy of CWI in pain management compared with passive recovery. We also aimed to identify which water temperature and immersion time provides the best results. Methods: MEDLINE, EMBASE, SPORTDiscus, PEDro and The Cochrane Library databases were searched up to January 2015. Only randomized controlled trials that compared CWI to passive recovery were included in this review. Results: Nine studies were included in the review and meta-analysis. The results of meta-analysis revealed that CWI has a more positive effect than passive recovery in terms of immediate (WMD=0.290, 95% CI [0.037, 0.543]; p=0.025) and delayed effects (WMD=0.315, 95% CI [0.048, 0.581], p=0.021). The pooled of studies that used water temperature of between 10-15°C demonstrated the best results for immediate (WMD=0.273, 95% CI [0.107, 0.440], p=0.001) and delayed effects (WMD=0.317, 95% CI [0.102, 0.532], p=0.004).
