Thesis (M.Tech.: Chiropractic)-Dept. of Chiropractic, Durban University of Technology, 2007 xi, 38 leaves, Annexures 1-2 / Background: Various congenital spinal anomalies are common findings in the general population. Their clinical significance is controversial with no definitive association been made between any specific congenital spinal anomaly to any clinical features. Project Design: This research study was designed in the form of a quantitative, non-experimental, empirical clinical survey. Method: Data was obtained from thoracic and lumbar spine radiographs contained in the Chiropractic Day Clinic at the Durban University of Technology from 1 January 1997 to 31 December 2005 and from the corresponding patient files. Through the research procedure, 519 thoracic and lumbar spine radiographs were located in the confines of the Chiropractic Day Clinic. Due to the exclusion criteria of a past or present history of trauma to the thoracic or lumbar spine areas, 147 radiographs were excluded. Objectives 1.To determine the period prevalence (1 January 1997 – 31 December 2005) of congenital thoracic and lumbar spine anomalies. 2.To determine if there is any association between the presenting clinical features and the congenital thoracic and lumbar spine anomalies in general. 3.To determine if there is any association between the presenting clinical features and individual congenital thoracic and lumbar spine anomalies. 4.To compare subjects presenting clinical features with reported clinical features from literature.

These effects have been associated with an increase in paraspinal muscle contractibility; it is unclear if this leads to an increase in paraspinal muscle endurance. Objectives: To determine the effect of sacroiliac joint (SIJ) manipulation compared to a placebo treatment of the SIJ on lumbar extensor muscle endurance time. Method: A randomised, placebo-controlled pre-test post-test experimental trial, involving 40 asymptomatic male participants divided into an intervention group receiving SIJ manipulation using an impulse adjusting instrument and a placebo group receiving a pre-load force without the delivery of an impulse thrust. Outcome measures were lumbar extensor muscle endurance time, surface electromyographic (SEMG) readings, lumbar spinal range of motion, paraspinal muscle length assessment and a subjective pain measurement. Results: There was a significant difference between the groups (p=0.004) with the SIJ manipulation group showing an increase in endurance time compared to the placebo group which showed a decrease. SEMG readings increased for both groups with no statistically significant difference between the groups (p>0.05). Only extension lumbar spinal range of motion significantly improved in both groups (p=˂0.001) with no significant differences between groups (p=0.876). Only one participant reported pain during the research procedure. Conclusions: SIJ manipulation may enhance the endurance of the paraspinal muscles. This study should be conducted in a larger sample to validate the findings.

Submitted in partial compliance with the requirements for the Masters’ Degree in Technology: Chiropractic, Department of Chiropractic, Durban University of Technology, Durban, South Africa, 2014. / Background Spinal manipulative therapy (SMT) is a commonly used therapeutic modality. It has been shown that neuromuscular reflexes are elicited during spinal manipulation resulting in changes in the surrounding muscle tonicity and seen as changes in surface electromyography. Despite this little is known about the effect that SMT may have on muscle function. Increased maximum voluntary contraction (MVC) of the paraspinal muscles has been observed following lumbar SMT compared to a control and sham treatment; however its effect on muscle endurance has not been investigated. The aim of this study was to determine the effect of lumbar SMT compared to a placebo treatment on lumbar extensor muscle endurance in asymptomatic individuals. Method This study was a quantitative double blinded, pre-test and post-test placebo controlled experimental trial. Forty asymptomatic participants were randomly allocated to one of two treatment groups. One group received a single SMT applied to the L3 vertebrae and the other received the pre-load force of the SMT but no thrust. Subjective (a self-report of pain/discomfort while performing the Biering-Sorensen test) and objective [surface electromyography (sEMG), paraspinal muscle endurance time and lumbar spine range of motion] measurements were taken pre- and post-intervention. The latest version of SPSS version (IBM SPSS Inc.) was used to analyse the data. A p-value < 0.05 was considered statistically significant. Independent t-tests were used to compare means and two-way factor ANOVA (for repeated measures) was used to compare the change in the two time points between the two treatment groups (intervention and control). RESULTS There were no statistically significant differences between the intervention and placebo groups in terms of subjective reports of pain/discomfort and objective evidence of surface EMG readings, paraspinal muscle endurance time and lumbar spine range of motion.

Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Department of Chiropractic, Durban University of Technology, Durban, South Africa, 2015. / Background: Spinal manipulative therapy (SMT) is a commonly used treatment for many musculoskeletal conditions although the exact mechanism explaining its effectiveness is not well understood. Several studies have investigated the effect of SMT on the paraspinal muscles where neuromuscular effects have been observed, however few studies have assessed whether these changes result in a change in the functioning of the paraspinal muscles. This study aimed to determine the effect of lower thoracic spinal manipulation compared to a placebo intervention on lumbar extensor muscle endurance in asymptomatic participants. Methodology: This was a quantitative, pre-test post-test, placebo controlled trial involving 40 male participants between the ages of 20 and 40 years. The participants were randomly allocated to either the lower thoracic spinal manipulation group or a placebo group. Manipulation was delivered using the Impulse Adjusting Instrument®. Objective measures included lumbar spinal range of motion, a paraspinal muscle endurance test, and surface electromyography readings. Subjective measures were the verbalisation of pain and/or discomfort during the paraspinal muscle endurance test. IBM® SPSS® statistics version 21 and STATA 11 were used to analyse the data. A p-value of <0.05 was considered statistically significant. Results: There were no statistically significant differences between the groups in terms of subjective and objective measurements. A trend of treatment effect was observed for paraspinal muscle endurance where the intervention group showed noticeable improvements in endurance scores. Conclusion: Further studies need to be conducted to determine if the trends observed would occur in a larger study population.

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

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.

Objetivos: comparar pacientes com estenose do canal lombar com indicação de cirurgia e um grupo controle, assintomáticos para esta doença, levando em consideração imagens de ressonância magnética (RM) e o questionário de Oswestry. Material e Método: Vinte e três pacientes com estenose do canal lombar foram comparados com um grupo controle de 17 indivíduos. Todos foram submetidos a RM e responderam ao questionário de Oswestry. Medidas qualitativas foram descritas segundo os grupos com uso de frequências absolutas e relativas e, verificada a existência de associação dessas medidas com uso do teste exato de Fisher. Medidas quantitativas foram descritas e comparadas entre os grupos com uso do teste Mann-Whitney. O teste de Spearman foi utilizado para avaliar a correlação entre os grupos. Resultados: Lombalgia foi a queixa mais frequente nos dois grupos. O índice de Oswestry mostrou média de percentual de invalidez de 45,69% no Grupo Estenose e 11,60% no Grupo Controle. A RM mostrou que a área de secção transversa do saco dural, o diâmetro do canal e a avaliação dos forames e recesso lateral estavam alterados em ambos os grupos. Conclusões: Não houve relação entre o grau de estenose do canal lombar mensurado em exame de RM com o índice de Oswestry em ambos os grupos / Abstract: Study design: Transversal Case-control, diagnostic study. Objectives: To verify the relationship between the degree of lumbar spinal canal stenosis (LCS), as seen in magnetic resonance imaging (MRI), and the severity of disability as seen in the Oswestry Index, in patients with LCS compared to controls without a diagnosed LCS. Methods: Twenty-three patients with a previous diagnosis of LCS were compared with a control group of 17 volunteers. All participants underwent MRI and answered the Oswestry questionnaire. Qualitative data were described according to the groups with the use of absolute and relative frequencies, and the association of these measures was checked by using the Fisher exact test. Quantitative measures were described and compared between groups using the Mann-Whitney test. Spearman's test was used as well. Results: Low back pain was the most frequent complaint in both groups. The Oswestry index showed average percentage of disability of 45.69% in patients with stenosis and 11.60% in the control group. MRI revealed that the dural sac cross-sectional area (DCSA), the diameter of the canal and the evaluation of lateral recesses and foramina were equally changed in both groups. Conclusions: There was no correlation between the degree of lumbar canal stenosis measured on MRI with the Oswestry Disability Index in both groups / Doutorado / Cirurgia / Doutor em Cirurgia
