The study of the lumbosacral plexus nerves constituents is extremely important because it relates the various evolutionary aspects of animal locomotion and posture. Considering that the femoral nerve is the largest cranial part of the lumbosacral plexus, aimed to describe the origins, distributions and ramifications of the femoral nerve in giant anteater (Myrmecophaga tridactyla), comparing with the literature described for domestic and wild animals in to establish correlations of morphological similarities and providing subsidies for similar areas. For the work three specimens were used prepared by injection of aqueous 10% formaldehyde in the femoral artery, for keeping the specimens and further dissection. The origin of the femoral nerve in the right and left sides, is the ventral brach of the lumbar spinal nerves one, two and three. As to the distributions and ramifications, the femoral nerve provides branches to the major and minor psoas muscle, lateral and medial iliac, pectineus, adductor magnus, sartorius and quadriceps. The anatomical origin of the femoral nerve in M. tridactyla shows a variation due to the difference in the number of vertebrae (L1, L2 and L3). But in most distributions and ramifications of the femoral nerve, this species has a significant degree of morphological similarities with domestic and wild animals in this study. / O estudo dos nervos constituintes do plexo lombossacral é de extrema importância, pois relaciona os diversos aspectos evolutivos de postura e locomoção dos animais. Considerando-se que o nervo femoral é o maior da parte cranial do plexo lombossacral, objetivou-se descrever as origens, distribuições e ramificações dos nervos femorais no Tamanduá bandeira (Myrmecophaga tridactyla), comparando com a literatura descrita para animais domésticos e silvestres, de modo a estabelecer correlações de similaridades morfológicas e fornecer subsídios para as áreas afins. Foram utilizadas três espécimes, preparadas através da injeção de solução aquosa de formaldeído a 10% via artéria femoral, para a conservação e posterior dissecação das mesmas. As origens nos antímeros direito e esquerdo, ocorreram dos ramos ventrais dos nervos espinhais lombares um, dois e três. As distribuições e ramificações foram observadas para os músculos psoas maior e menor, ilíacos lateral e medial, pectíneo, adutor magno, sartório e quadríceps femoral. Com base nas origens dos nervos femorais do M. tridactyla, uma reconfiguração foi observada devido à variação no número de vértebras lombares (L1, L2 e L3). Entretanto, uma similaridade morfológica parcial foi mantida quanto às distribuições e ramificações, quando comparadas aos animais domésticos e silvestres considerados neste estudo. / Mestre em Ciências Veterinárias

Os tumores paravertebrais e intracraniais, também chamados de cânceres do Sistema Nervoso Central, tem origem no cérebro, nervos cranianos e meninges. Uma nova modalidade de braquiterapia começou a ser usada nesta última década. Neste procedimento, placas poliméricas flexíveis, carregando fósforo-32, são colocadas próximas ou em contato ao tumor para o tratamento. Este tratamento apresenta vantagens em relação aos demais porque aplica uma alta taxa de dose no tumor poupando tecidos sadios. A produção destas placas ainda é pouco estudada, embora já existam resultados satisfatórios no seu uso para o tratamento dos cânceres do sistema nervoso central. Neste trabalho foram realizados estudos iniciais para a produção deste tipo de placas poliméricas para braquiterapia. Foram avaliadas as propriedades mecânicas e a capacidade de imobilização de material radioativo de duas resinas comercias, uma poliuretânica e outra epoxídica, com e sem presença de substrato de policarbonato. Os testes iniciais apontaram o uso da resina epoxídica como melhor alternativa e com o uso dela foram feitos os primeiros protótipos e testes. O uso do policarbonato como substrato não foi necessário em uma das metodologias, facilitando o procedimento, mas oferecendo uma barreira menor de segurança. Os ensaios de tração mostraram que a adição de solução ácida à resina epóxi alterou suas características mecânicas, mas houve uma pequena melhora em sua flexibilidade. Os testes de adesão evidenciaram uma melhor adesão da resina à face texturizada do policarbonato. A termogravimetria mostrou que a solução ácida adicionada a resina fica presa à estrutura mesmo com elevações de temperatura acima de 100°C. A resina epoxídica utilizada teve a capacidade de incorporar o material radioativo em forma de solução ácida e manter-se estanque após testes de esfregaço e imersão em líquido quente. De acordo com os resultados obtidos, a produção destas placas com resina epoxídica é possível e atende às normas internacionais de segurança contra vazamento de material radioativo para fontes utilizadas em braquiterapia. / Dissertação (Mestrado em Tecnologia Nuclear) / IPEN/D / Instituto de Pesquisas Energeticas e Nucleares - IPEN-CNEN/SP

As características do crescimento craniofacial dos indivíduos portadores de má oclusão de Classe II na fase de crescimento, são de intenso interesse dos ortodontistas por esta má oclusão representar uma alta porcentagem dos casos em tratamento nos consultórios. Esta investigação objetivou estudar cefalométrica e comparativamente o crescimento craniofacial em crianças leucodermas portadoras de má oclusão de Classe II e de Oclusão Normal. Foram utilizadas 148 telerradiografias em norma lateral de 78 meninos e 70 meninas, faixa etária dos 7 aos 12 anos, portadores de má oclusão de Classe II, e 60 telerradiografias em norma lateral de 30 meninas e 30 meninos com Oclusão Normal. As amostras foram divididas considerando-se o estágio da maturação das vértebras cervicais pelo método de Hassel e Farman(HASSEL; FARMAN 1995), estando os grupos nos níveis Iniciação(I), Aceleração (A) e Transição (T) do desenvolvimento esquelético. Foram utilizadas as grandezas SNA, A-Nperp e Co-A para avaliar o componente maxilar; SNB, P-Nperp, Co-Gn, Co-Go e Go-Gn para o componente mandibular; ANB representou a relação maxilomandibular; SN.GoGn, FMA, NS.Gn, BaN.PtGn e ENA-Me para o componente vertical, e o ângulo da base do crânio representado por NS.Ba. O teste t independente foi aplicado: entre os grupos para verificar a precocidade dos índices entre os gêneros; em cada grupo e índice nos gêneros feminino e no masculino; na comparação entre os grupos em cada índice nos gêneros feminino e no masculino; na comparação entre os grupos na fase IT (Iniciação Transição) em cada gênero. Os resultados mostraram: precocidade do índice A (aceleração) no gênero feminino do grupo de Classe II. Na comparação entre os gêneros do grupo de Classe II no nível I, as medidas de Co-A, Co-Gn, Go- Gn e ENA-Me foram maiores no gênero masculino, que também apresentaram significância estatística no nível A, acompanhado de um maior FMA; no nível T, apenas Co-Gn e ENA-Me foram maiores no grupo de Classe II do gênero masculino. Na comparação entre os gêneros do grupo de Oclusão Normal no nível I, as medidas de FMA e NS.Gn foram maiores no gênero masculino, que também apresentaram significância estatística no nível A, acompanhados do Co-A, SNB, PNPerp, Co-Gn e ENA-Me, enquanto o gênero feminino apresentou maior valor de NSBa; no nível T, apenas Co-Go foi estatisticamente maior no gênero masculino. Na comparação entre os grupos do gênero feminino e nível I, o grupo de Classe II apresentou significância estatística para as variáveis A-Nperp, Co-Go, ANB, SN.GoGn, NS.Gn, BaN.PtGn, ENA-Me e NSBA; na fase A, as medidas Co-Go, ANB, NS.Gn, ENA-Me e NSBa foram maiores no grupo de Classe II que apresentou menor BaN.PtGn; na fase T, apenas Co-Go e BaN.PtGn permaneceram significantes para o grupo de Classe II. Na comparação entre os grupos do gênero masculino e nível I, as variáveis SNB, Co-Gn, Co-Go, ANB, ENA-Me e NSBa foram maiores no grupo de Classe II; no nível A, apenas SNB, ANB e BaNPtGn foram significantes, e permaneceram também no nível T. Avaliando os grupos do gênero feminino na fase IT, as variáveis A-Nperp e Co-Go foram maiores no grupo de Classe II, acompanhados de deficiente relação entre as bases ósseas (ANB), um padrão de crescimento mais vertical (SN.GoGn, NS.Gn, BaN.PtGn, ENA-Me) e maior deflexão da base do crânio (NSBa). Na comparação entre os grupos do gênero masculino na fase IT, o grupo de Classe II apresentou maior retrusão mandibular (SNB), maior ANB, tendência de crescimento craniofacial vertical (BaN.PtGn) e maior deflexão da base do crânio (NSBa). Ficou explícito que a má oclusão de Classe II não se auto corrige, que o crescimento é indomável, imutável e individual, regido pela soberania da genética que é responsável pelo estabelecimento e manutenção do padrão facial durante a vida. Sustentando a intervenção terapêutica nestes níveis de grande expectativa de crescimento determinado pela maturação esquelética, o ortodontista terá a pretensão de contrariar a genética e corrigir a discrepância esquelética presente na Classe II. Essa concepção deverá estar edificada sobre a soberania do crescimento para que o ortodontista vise a prática mais lógica e menos frustrante, sabendo superar as limitações dos resultados, mesmo diante de tratamentos ortopédicos bem sucedidos. / Craniofacial growth characteristics of individuals with Class II malocclusion at the stage of growth are of intense interest os Orthodontists for this malocclusion represents a high percentage of cases where treatment in clinics. The purpose of this study was to compare the craniofacial growth changes through 148 (78 males and 70 females) lateral cephalograms of untreated subjects with Class II Division 1 malocclusion, at a mean age of 10,03 years, with those lateral cephalograms of 60 (30 males ans 30 females) subjects with normal occlusion, at a mean age of 10 years, divided by stages of development (Initiation, Acceleration and Transition) as defined by a biological indicator of cervical vertebrae skeletal maturity (HASSEL; FARMAN 1995). Cephalometric measurements in Class II and Normal Occlusion evaluated was SNA, A-Nperp, Co-A, SNB, P-Nperp, Co-Gn, Co-Go, Go-Gn, ANB, SN.GoGn, FMA, NS.Gn, BaN.PtGn, ENA-Me and NS.Ba. Statistical comparision of the growth changes in the study groups, stages os development and gender were performed with independent t test. Evaluating the Class II group, mens presented Co-A, Co-Gn, Go-Gn and ENA-Me larger at stage I and at stage A accompanied by greater FMA; in stage T, just Co-Gn and ENA-Me were the largest group of Class II of male gender. Evaluating the Normal Occlusion group, mens presented FMA, NSGn larger at stage I and at stage A, accompanied by greater Co-A, SNB, P-Nperp, Co-Gn and ENA-Me, while the female gender has greater value of NSBa; at stage T, only Co-Go was statistically higher in mens gender. In the comparision between the groups of female gender and stage I, the group Class II presented statistical significance for the variables A-Nperp, Co-Go, ANB, SN.GoGn, NS.Gn, BaN.PtGn, ENA-Me e NSBA; at stage A, Co-Go, ANB, NS.Gn, ENA-Me and NSBa were the largest group of Class II that had less BaN.PtGn; at stage T, just Co-Go and BaN.PtGn remained significant for the group Class II. In the comparision between the groups of male gender and stage I, the group Class II presented statistical significance for the variables SNB, Co-Gn, Co-Go, ANB, ENA-Me and NSBa; at stage A, just SNB, ANB and BaNPtGn were significant, and remained in stage T. Evaluating the female gender groups in phase IT, the variables A-Nperp and Co-Go were the largest group of Class II, accompanied by poor relations between the bases described by ANB, more vertical growth pattern (SN.GoGn, NS.Gn, BaN.PtGn, ENA-Me) and greater NSBa. In the comparision between the groups of male gender in phase IT, the group Class II presented greater SNB, ANB, vertical craniofacial growth trend (BaN.PtGn) and greater deflexion at the base of the skull (NSBa).

L’exploitation de données radiographiques, en particulier pour la reconstruction 3D du rachis de patients scoliotiques, est un prérequis à la modélisation personnalisée. Les méthodes actuelles, bien qu’assez robustes pour la routine clinique, reposent sur des ajustements manuels fastidieux. Dans ce contexte, ce travail de thèse vise à la détection automatisée de points anatomiques spécifiques des vertèbres, permettant ainsi des ajustements automatisés. Nous avons développé premièrement une méthode originale de localisation de coins de vertèbres cervicales et lombaires sur les radiographies sagittales. L’évaluation rigoureuse de cette méthode suggère sa robustesse et sa précision. Nous avons ensuite développé un algorithme pour le problème pertinent cliniquement de localisation des pédicules sur les radiographies coronales. Cet algorithme se compare favorablement aux méthodes similaires dans la littérature, qui nécessitent une saisie manuelle. Enfin, nous avons soulevé les problèmes, relativement peu étudiés, de détection, identification et segmentation des apophyses épineuses du rachis cervical dans les radiographies sagittales. Toutes les tâches mentionnées ont été réalisées grâce à une combinaison originale de descripteurs visuels et une classification multi-classe par Random Forest, menant à une nouvelle et puissante approche de localisation et de segmentation. Les méthodes proposées dans cette thèse suggèrent un grand potentiel pour être intégré à la reconstruction 3D du rachis, utilisée quotidiennement en routine clinique. / Exploitation of spine radiographs, in particular for 3D spine shape reconstruction of scoliotic patients, is a prerequisite for personalized modelling. Current methods, even though robust enough to be used in clinical routine, still rely on tedious manual adjustments. In this context, this PhD thesis aims toward automated detection of specific vertebrae landmarks in spine radiographs, enabling automated adjustments. In the first part, we developed an original Random Forest based framework for vertebrae corner localization that was applied on sagittal radiographs of both cervical and lumbar spine regions. A rigorous evaluation of the method confirms robustness and high accuracy of the proposed method. In the second part, we developed an algorithm for the clinically-important task of pedicle localization in the thoracolumbar region on frontal radiographs. The proposed algorithm compares favourably to similar methods from the literature while relying on less manual supervision. The last part of this PhD tackled the scarcely-studied task of joint detection, identification and segmentation of spinous processes of cervical vertebrae in sagittal radiographs, with again high precision performance. All three algorithmic solutions were designed around a generic framework exploiting dedicated visual feature descriptors and multi-class Random Forest classifiers, proposing a novel solution with computational and manual supervision burdens aiming for translation into clinical use. Overall, the presented frameworks suggest a great potential of being integrated in current spine 3D reconstruction frameworks that are used in daily clinical routine.

Ce travail de thèse porte sur des études de la cinématique 3D de la colonne cervicale in vivo chez des sujets asymptomatiques (N=30); il se divise en quatre parties. La colonne cervicale de tous les sujets est reconstruite en 3D à partir des images de tomodensitométrie dans différentes positions :position neutre, rotation axiale gauche et droite et lors du positionnement pré-manipulatif de la tête.<p>La première partie de ce travail a comme objectif fondamental de déterminer la cinématique 3D inter-segmentaire de la colonne cervicale, lors de la rotation axiale maximale de la tête. Les valeurs déterminées pour tous les paramètres cinématiques 3D vont nous servir comme base de données de référence.<p>Dans la deuxième partie, nous souhaitons contribuer à une meilleure compréhension du rôle des ligaments alaires lors de la rotation axiale. Pour cela, nous avons déterminé la cinématique 3D de l’os occipital par rapport à l’axis. Même s’il est inhabituel d’ignorer l’atlas, il nous a semblé plus juste de considérer les segments osseux qui livrent les principales insertions des ligaments alaires. La biomécanique de ces ligaments dépend des mouvements de l’os occipital par rapport à l’axis.<p>La troisième partie est orientée vers l’objectif principal de la thèse qui vise à déterminer les amplitudes articulaires inter-segmentaires lors de la position pré-manipulative de la colonne cervicale. Cette étude va nous permettre de comparer les amplitudes atteintes lors de la mise en position pré-manipulative avec celles des mouvements physiologiques.<p>La dernière partie a pour objectif principal de déterminer la longueur du trajet de l’artère vertébrale en position neutre, et ensuite de comparer la variation de longueur du trajet de l’artère vertébrale entre la position en rotation axiale maximale de la tête d’une part, et la position pré-manipulative d’autre part, donc lors de l’application d’une technique manipulative à composantes multiples telle qu’utilisée régulièrement en ostéopathie.<p>En comparant la position pré-manipulative à la rotation physiologique, les résultats les plus importants de ce travail sont :(1) les amplitudes segmentaires sont inférieures pour la position pré-manipulative et (2) l’artère vertébrale est moins allongée lors de cette mise en position que lors de la rotation physiologique. Ces deux faits, jusque-là inédits, sont importants en clinique ostéopathique courante et montrent l’importance d’un choix judicieux de la technique manipulative et de son exécution.<p> / Doctorat en Sciences de la motricité / info:eu-repo/semantics/nonPublished

Submitted in fulfillment of the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, Durban, South Africa, 2017. / Mid-back pain (mbp) is defined as pain occurring within the limits of the third thoracic (T3) and ninth thoracic (T9) vertebrae, caused by the dysfunction of the musculoskeletal structures in the thoracic spine. It can present as pain and/ burning between the shoulder blades with reduced thoracic spine mobility and increased muscle tension. Congenital disorders such as scoliosis and Scheuermann’s disease, or acquired disorders such as thoracic facet and costovertebral joint dysfunction may cause mbp. The thoracic facet and costovertebral joints are similar in anatomy and share a mutually dependent biomechanical relationship. There were a handful of controlled studies that highlighted the effectiveness of thoracic facet manipulation on mbp, but there were none on the effects of costovertebral manipulation on mbp. Objectives The aim of this study was to investigate the immediate effects of the combination of thoracic facet and costovertebral joint manipulation on mbp in terms of pain perception, pressure pain thresholds (PPT) and thoracic spine range of motion (ROM). Design A prospective single-blind randomised comparative clinical trial. Setting This study was conducted in a university setting at the Durban University of Technology Chiropractic Day Clinic Participants Fifty participants were recruited via responses to advertisements placed around the Durban University of Technology (DUT) campuses and individuals presenting at the Chiropractic Day Clinic (CDC). Intervention The participants were divided into two groups of twenty-five. Group A received the thoracic facet joint manipulations and Group B received a combination of the thoracic facet and costovertebral joint manipulations. Outcome measures All subjective and objective measurements were taken before and after the application of the manipulations. Pain perception i.e. subjective measurement) was measured by the Numerical Pain Rating Scale (NPRS), pressure pain thresholds (PPT) (i.e. objective measurement) were measured by the Wagner’s FDK Force Gage Algometer and thoracic spine range of motion (ROM) i.e. objective measurement was measured by the Saunders Digital Inclinometer. Results The data was analyzed using the latest version of SPSS and a p-value = 0.05 was used to determine statistical significance. Descriptive statistics in the form of univariate analysis described the data in terms of measures of central tendency and measures of dispersion. Data that was distributed normally was analyzed using the t-test and ANOVA. Data that was distributed abnormally was analyzed using the non-parametric Wilcoxon ranked and Mann Whitney tests. Nominal and ordinal data was analyzed using the Chi squared test. The results of the intra-group analysis indicated a statistically significant decrease in pain perception (p ≤ 0.000), increase in PPT (p ≤ 0.05) and decrease in thoracic spine ROM (p ≤ 0.000). However, the results for the inter-group analysis indicate there was no statistically significant difference in pain perception (p = 0.386), PPT (p > 0.05) and thoracic spine ROM (p >0.05) between Group A and Group B. Conclusions These results showed that the combination of thoracic facet and costovertebral joint manipulation was as effective as thoracic facet joint manipulation alone, in the treatment of mbp. These findings suggested that manipulation of the costovertebral joints may not be necessary for the effective treatment of mbp. / M

M.Tech. / aim of this unblinded randomized control study was to compare Chiropractic Adjustive Therapy (CAT) to Interferential Current Therapy (IFC) as treatment for Painful Minor Intervertebral Dysfunction (PMID) in the lumbar spine. The effects of CAT and IFC on lumbar spine range of motion (ROM) and pain relief from PMID were also examined. The participants of the trials were treated at the Chiropractic Day Clinic at the University of Johannesburg. Thirty participants presenting with Low Back Pain (LBP) and PMID on segmental intervertebral examination were used for this study and divided into two groups of fifteen. Group A participants were treated with CAT applied to the painful intervertebral segment. Group B participants were treated with IFC over the painful intervertebral segment. The objective data for this research was recorded by the readings obtained from the application of transverse pressure by a Pressure Algometer to the lateral aspect of a painful spinous process. Further objective readings were taken using a Digital Inclinometer to measure the participants Range of Motion (ROM). Subjective data was obtained by an Oswestry Pain and Disability Index (ODI). The subjective and the objective data were both recorded at the first, fourth and seventh visit which took place over a three week period. The results of the study showed that Group A had a statistically significant decrease in Pressure Algometer Readings and ODI scores. Group A also showed a statistically significant improvement in ROM readings for Left Lateral Flexion, Left Rotation and Right Rotation. Group B did not show any statistical significance in either the subjective or objective data. Importantly, an Inter-group comparison for the Pressure Algometer Readings also revealed an increasing statistically significant difference between Group A and Group B from the first to the fourth and seventh visit. The pain elicited by transverse pressure to a spinous process is core to the diagnosis of PMID, which can result in many pain syndromes of vertebral origin (Maigne, 2006). This research provides evidence that CAT is more beneficial than IFC for the treatment of PMID in the lumbar spine over a short and longer period of time.

Thesis (MScPhysio)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Introduction-Groin injuries are among the top six most cited injuries in soccer and account for 10-18 per cent of all injuries reported in contact sport. Groin pain can result from a variety of pathologies, but according to literature, 63 per cent of groin pain is due to adductor pathology. Objective-The objective of this study was to explore if there are kinematic differences in the hip joint in sports participants with groin pain compared to matched healthy controls. Study design A cross sectional, descriptive study was conducted. Study setting-The study was conducted at the FNB -3D motion analysis laboratory at the University of Stellenbosch, South Africa. Outcome variables-The dependent variables included hip kinematics in the sagittal, frontal and transverse planes at foot strike, lowest vertical point of the pelvis and total range of hip motion during a single leg drop landing. Methodology-The study sample comprised 20 male club level soccer-and, rugby players, running and cycling participants between the ages of 18-55 years of age. Ten of the subjects had chronic groin pain and the other ten were healthy matched controls. An eight-camera Vicon system was used to analyse the kinematics of the hip joint during single leg drop landing. For the purpose of comparison, the data was analysed for participants with unilateral groin pain and matched controls (n=14) and participants with bilateral groin pain and controls (n=6). The full set of data was subdivided for analysis into three distinct sub-groups. Unilaterally injured groin cases (n=7) were matched with seven healthy controls for analysis. Bilaterally injured groin cases (n=3) were matched with three healthy controls. Results-Cases with unilateral groin pain at initial contact had significantly more abduction of the hip joint when compared to controls (p<0.05). The effect size of this difference was large (0.94). Cases with unilateral groin pain also demonstrated greater hip internal rotation while the controls had external rotation (p<0.05) during a drop landing activity. Bilaterally injured groin cases landed with significantly (p=?) greater ranges of hip flexion as well as in significantly (p=?) more hip abduction during a drop landing activity. They also demonstrated greater total range of motion in the frontal plan when compared to controls. Groin pain cases overall demonstrated greater ranges of motion and tended to land in more abduction compared to controls. Conclusion-This study found that during a single leg drop landing, sports participants with unilateral chronic groin pain landed with significantly greater hip abduction and exhibited larger total range of motion in the transverse plane, which may indicate impaired stability of the hip complex when compared to controls. / AFRIKAANSE OPSOMMING: Inleiding-Liesbeserings is een van die top ses mees prominente sokker beserings. Dit beloop 10-18 persent van alle beserings wat in kontaksport aangemeld word. Liespyn kan die gevolg wees van ‘n verskeidenheid patologië, maar volgens die literatuur is 63 persent van liespyn as gevolg adduktor patologie. Doelwitte-Die doelwit van hierdie studie was om ondersoek in te stel of daar enige kinematiese veranderinge in die heupgewrig is in spelers met liespyn in vergelyking met dieselfde vergelykbare spelers sonder liespyn. Studie Ontwerp-‘n Deursnit, beskrywende studie was onderneem. Studie Omgewing-Die studie was uitgevoer by die FNB-3D bewegingsanalise laboratorium van die Stellenbosch Universiteit, Suid-Afrika. Uitkomsveranderlikes-Die afhanklike veranderlikes het in gesluit die heup kinematika in die sagitale, frontale en transvers vlakke met voet kontak endie laagste vertikale punt van die pelvis sowel as die totale heup omvang van beweging gedurende een been landing. Metodologie-Die studie populasie het bestaan uit 20 manlike sokker- en, rugbyspelers, hardlopers en fietsryers tussen die ouderdomme van 18 en 55 jaar. Tien van die deelnemers het kroniese liespyn gehad en die ander tien in die gelyke gesonde groep was sonder liespyn. Die agt kamera Vicon sisteem was gebruik om die kinematika van die heupgewrig te analseer tydens een been landing. Vir die doel om ‘n vergelyking te kan maak, was die data geanaliseer van deelnemers met unilaterale liespyn en die vergelykende groep sonder liespyn (n=14) en deelnemers met bilaterale liespyn en hulle vergelykende groep sonder liespyn (n=6).. Die volledige stel data was onderverdeel in drie afsonderlike sub groepe. Vir die analiese was unilaterale liesbeserings (n=7) vergelyk met sewe deelnemers sonder liespyn in die kontrolegroep. Deelnemers met bilaterale liesbeserings (n=3) was vergelyk met drie in die kontrolegroep. Resultate-Die deelnemers met unilaterale liespyn het met eerste kontak beduidend meer abduksie van die heupgewrig gehad in vergelyking met die kontrolegroep (p<0.05). Die effek van hierdie verskil was groot (0.94). Die deelnemers met unilaterale liespyn het ook ‘n grooter interne rotasie getoon, terwyl die kontrole groep meer eksterne rotasie gedemonstreer het (p<0.05) met landing. Deelnemers met bilaterale liespyn het beduidend (p=?) meer heup fleksie en abduksie omvang van beweging tydens landing. Hulle het ook ‘n groter totale heup omvang van beweging in die frontale vlak gehad in vergelyking met die kontrolegroep. Deelnemers met liespyn het oor die algemeen ‘n grooter omvang van beweging getoon, en was geneig om met meer abduksie van die heup te land as die kontrolegroep. Gevolgtrekking-Die studie toon dat deelnemers met kroniese unilaterale liespyn, tydens een been landing, beduidende meerheup abduksie toon en dat die heup in die transverse vlak meer totale omvang van beweging gebruik wat kan dui op onstabiliteit in die heupkompleks in vergelyking met die kontrolegroep.
