It is well establish that posture deformities are a common problem among children that is often ignored by parent and teachers. Posture deformities in children could be related to their socio-economic status, lifestyle, culture, tradition, environmental factors, as well as activity levels and are associated with numerous adverse health effects, which include lung and heart defects, indigestion and back pain. Children who experience back pain are at increased risk of having back pain as adults. The economic impact of back pain affects the industry, were back problems are the most expensive type of injury claim. The increase in spinal problems, such as lower back pain in children and adolescents, points to the need for continued screening. It is suggested that early detection of postural deviation could provide an improve chance for corrective remedies and posture development. On investigating the relevant literature it becomes clear that attempts to define the prevalence of posture deformities among children have focused on reporting selected deformities only. Consequently the literature contains insufficient information on posture deformities involving the entire musculoskeletal system, as well as the prevalence of posture deformities among black African people. The purpose of this study was firstly to determine the incidence of posture deviations among black African children in the North West Province and secondly to determine the difference in the prevalence of posture deformities between boys and girls. In a longitudinal study posture deformities including the entire musculoskeletal system were assessed in 251 schoolchildren (136 girls and 115 boys). Posture screening was done according to the New York Posture test and a posture grid. Subjects were evaluated in a standing position from the rear and lateral side. Foot deformities (flat foot) were also measured with the use of white chalk and a black board. Thereafter the "Adam's test" (forward bending test) were used for further scoliosis evaluation. The prevalence of posture deformities was reported to be high among black African schoolchildren. The incidence of lordosis (84%) and protruding abdomen (67%) was the highest, while twisted head (8%) was reported as the lowest. Gender difference in the prevalence of posture deformities was also found, with a higher incidence of posture deformities reported in girls (54%) as in boys (46%). / Thesis (M.Sc.

Correct posture is the basis for normal development and function of chest box, extremities and internal organs. Irregular posture is one of the most widespread disorders of musculoskeletal system, which might be caused by the low level of culture and lack of education. It has an influence on children‘s health, physical and psychological well-being. Lack of assessment and delay of treatment might worsen situation and progress into complicated forms of disorders. Aim of the work: to evaluate posture of 11–12 years old children in sagittal and frontal planes and effects of physical therapy. Contingent: 96 11–12 years old children were participated in the first assessment: 59 girls and 37 boys. 64 children were participated in the second assessment: 33 girls and 31 boys. Methods: inspection, palpation, cirtometry, scoliometry, SPSS software. Results: Distribution of curves of column in frontal and sagittal planes after physical therapy were the same among boys and girls as well as children of 1’st and 2’nd group. Analyzing data of first and second assessments we can say, that physical therapy had no influence on boy’s kyphosis and lordosis, but it had a statistically significant positive effects on girl’s parameters of kyphosis and lordosis. Conclusions: posture disorders in frontal and sagittal planes are still widespread among schoolchildren. Physical therapy is very important for the correction of schoolchildren’s posture. Special physical exercises had to be used under... [to full text]

Profesor especializado en danza / La formulación de este trabajo está orientada hacia los estudiantes de la Etapa Básica y el Primer año Superior de la carrera de Licenciatura en Artes con mención en Danza de la Facultad de Artes de la Universidad de Chile y se contextualiza primeramente en una breve descripción de los aspectos necesarios para entender el tema en cuestión, referente a la anatomía de la postura humana y sus desequilibrios. Éstos se fundamentan en los estudios de anatomía y fisiología del cuerpo humano y enfatizan en las estructuras óseas y musculares en donde se localiza el problema postural de la hiperlordosis lumbar, como son la columna vertebral y la pelvis. De igual manera, define los componentes del centro de energía y la forma de trabajarlo en Pilates, paralelo a un enfoque específico de la danza Contemporánea referente al sistema de trabajo Laban-Bartenieff, el cual no es aplicado directamente en todas las asignaturas de la Licenciatura, sin embargo muchas utilizan conceptos y conexiones aplicadas a la postura y el movimiento. En conjunto con las entrevistas y observaciones y de acuerdo a las competencias requeridas en los primeros años de estudio de la carrera de Danza versus las condiciones y habilidades de cada estudiante con respecto a su condición de hiperlordosis lumbar, se realizó una propuesta de ejercicios a modo de programa. Éste se origina en la aplicación del trabajo de Suelo del Método Pilates Clásico o Auténtico, el cual incluye rutinas específicas que les permitirán a los estudiantes localizar el centro de energía para entregar soporte desde él a todo el resto del cuerpo, mejorando su conciencia corporal y optimizando su alineación postural, por tanto, la eficiencia energética y la mecánica corporal.

Foi avaliada a participação dos corpos vertebrais e discos intervertebrais na lordose lombar e, a contribuição destes nas curvaturas lombares de diferentes magnitudes. Foram avaliadas as radiografias lombares em perfil de 350 adultos assintomáticos (143 homens e 207 mulheres, idade média 29 anos). Foram mensuradas a curvatura lombossacra (L1S1), a curvatura lombolombar (L1L5), a angulação de cada corpo vertebral e cada disco intervertebral por meio de uma variação do método de Cobb. A participação percentual dos corpos vertebrais e dos discos intervertebrais na curvatura lombossacra também foi determinada. Comparações entre os sexos e as faixas etárias foram realizadas. Os indivíduos foram divididos em três subgrupos populacionais, de acordo com a magnitude da lordose lombossacra, de modo a separar os indivíduos pertencentes aos extremos da curva de distribuição. Os componentes da curvatura lombar (corpos vertebrais e discos intervertebrais) foram comparados nestes três subgrupos. A medida da curvatura lombossacra no grupo inicial foi -60,9o (-33o a -89o). Os corpos vertebrais eram cifóticos em L1 (2,15o), tendiam ao neutro em L2 (-0,36o) e eram progressivamente lordóticos de L3 (-1,56o) a L5 (-9,23o). Os discos intervertebrais eram progressivamente lordóticos (variando de -4,99o em L1-L2 a -15,58o em L5-S1). Os corpos vertebrais e discos intervertebrais apresentaram participação progressivamente maior na curvatura lombossacra no sentido crânio-caudal. Os discos intervertebrais participaram com cerca de 80% da curvatura lombossacra, sendo que os elementos mais caudais (corpos vertebrais L4 e L5 e discos intervertebrais L4-L5 e L5-S1) corresponderam a mais de 65% da curvatura lombossacra. Os indivíduos mais velhos apresentaram medidas das curvaturas lombares maiores cerca de 4º em comparação aos indivíduos mais jovens, havendo diferença significante para as medidas dos corpos vertebrais L2 e L5 e o disco intervertebral L3-L4, sendo maiores as medidas nos indivíduos mais velhos. As medidas das curvaturas lombares e dos corpos vertebrais L2 e L4 apresentaram diferença estatisticamente significante entre os sexos, sendo as medidas maiores nos indivíduos do sexo feminino. A curvatura lombossacra apresentou média de -46,9° no subgrupo lordose menor; -61,59° no subgrupo lordose intermediária e; -74,13° no subgrupo lordose maior. A curvatura lombolombar apresentou média de -33,28° no subgrupo lordose menor; -45,34° no subgrupo lordose intermediária e; -56,96° no subgrupo lordose maior. Os corpos vertebrais e os discos intervertebrais apresentaram medidas absolutas menores no subgrupo lordose menor do que as dos subgrupos lordose intermediária e lordose maior, mas a participação dos discos intervertebrais na curvatura lombossacra no subgrupo lordose menor (88%) foi maior que nos subgrupos lordose intermediária (81%) e no subgrupo lordose maior (75%). Complementarmente, os corpos intervertebrais apresentaram maior participação nos subgrupos lordose maior e lordose intermediária. Individualmente, os corpos vertebrais apresentaram maior participação no subgrupo lordose maior, exceto pelo corpo vertebral L5 que apresentou maior participação no subgrupo lordose menor. A maior participação percentual dos discos intervertebrais no subgrupo lordose menor era devida à inclinação cifótica dos corpos vertebrais mais cefálicos (especialmente L1 e L2) no subgrupo lordose menor do que nos demais subgrupos, que, por um efeito compensatório, causava uma maior participação discal nas curvaturas menores. Os demais subgrupos apresentavam os corpos vertebrais cefálicos com inclinação muito mais lordótica do que o observado no subgrupo lordose menor. Concluímos que os discos intervertebrais são os principais responsáveis pela curvatura lombar e que a contribuição dos corpos vertebrais e discos intervertebrais na lordose lombar difere entre indivíduos com curvaturas de diferentes magnitudes. Apesar de ocorrer um aumento gradual do acunhamento lordótico do corpo e disco a cada nível vertebral conforme aumenta a medida da lordose, as vértebras mais cefálicas provocam uma diferença na contribuição percentual entre discos intervertebrais e corpos vertebrais nas curvaturas de tamanhos diferentes. / The vertebral bodies and intervertebral discs participation in lumbar lordosis and their contribution between lumbar curves of different size were studied. 350 lumbar spine radiographs of asymptomatic adults (143 men and 207 women, average age 29 years) were evaluated. Lumbosacral (L1S1) and lumbolumbar (L1L5) curves and the angular inclination of each vertebral boby and intervertebral disc were measured using a Cobb method variant. The percentile participation of each vertebral body and intervertebral disc in the lumbossacal curve was calculated. Sex and age were compared. The subjects were separated in tree subgroups, in acording to lumbosacral curve size. The compounds of lumbar curve (discs and vertebrae) were compared in these tree subgroups. The mean lumbosacral curve was ?60,9º (-33º to ?89º). L1 vertebral body was kyphotic (2,15º), L2 was neutral (-0,36º), and the other ones were progressively lordotic from L3 (-1,56º) to L5 (-9,23º). The intervertebral discs were progressively lordotic from L1-L2 (?4,99º) to L5-S1 (?15,58º). Both vertebrae and discs showed a progressive participation in cephalic-caudal direction. The participation of discs was about 80% of lumbosacral curve, and the caudal elements (L4, L5 vertebrae and L4-L5, L5-S1 discs) contributed far 65% of the curve. The older subjects presented lumbar curves larger than younger 4º average, with significant statistical difference to L2, L5 and L3-L4 measures, with older subjects presenting bigger angular values. There were statistical differences of lumbar curves, L2 and L4 measures between sexes, with females presenting bigger values. The lumbosacral curve presented average -46,9º in minor lordosis subgroup, -64,59º in intermediate lordosis sugbroup, and ?74,13º in major lordosis subgroup. The lumbolumbar curve presented average ?33,28º in minor lordosis subgroup, -45,34º in intermediate lordosis subgroup, and ?56,96º in major lordosis subgroup. The absolut values of vertebrae and discs angles were smaller in minor lordosis subgroup than in major lordosis subgroup, but the intervertebral discs participation of was bigger in minor lordosis subgroup (88%) than intermediate lordosis (81%) and major lordosis (75%) subgroups. Complementarely, the vertebrae had a bigger participation in intermediate and major lordosis subgroups. Individually, the vertebrae presented a larger participation in major lordosis subgroup, excepting L5 that presented bigger participation in minor lordosis subgroup. The discs presented larger participation in minor lordosis subgroup. That is consequence of a more kyphotic inclination of the cephalic vertebrae in minor lordosis subgroup than the other ones, causing a compensating effect, with a larger disc participation in the small curves. The intermediate and major lordosis subgroups had the cephalic vertebrae more lordotic than that of the minor lordosis subgroup. We concluded that the intervertebral discs are the main responsible for the lumbar curve angulation and that the contribution of vertebrae and discs in lumbar curves of different sizes is not equal. In spite of a gradual increase of lordotic wedging while lumbar curve increase, the cephalic vertebrae make the disc and vertebrae participation different between different magnitude lumbar curves.

The dimensions of the lumbar vertebrae are examined in order to determine if these measurements can be used to predict the age of an individual, and if the lumbar vertebrae exhibit sexual dimorphism. Various statistical techniques were utilized to analyze several dimensions of the lumbar vertebrae. Aging patterns in the lumbar elements are distinct between males and females, and females exhibit compression of the L3 element, which may be related to vertebral wedging. Some dimensions of the lumbar vertebrae are sexually dimorphic.

Champagne dilution of coat color in horses is caused by dominant gene action. Three sire families were identified as segregating for this trait. Genome wide linkage analysis using 104 microsatellite DNA markers was used to map the gene to ECA14 (LOD > 11.0). Four genes, namely SPARC, SLC36A1, SLC36A2 and SLC36A3, were selected from the region implicated by linkage and their exons sequenced. DNA sequences were compared for two homozygotes for Champagne dilution, two heterozygotes and two horses without dilution. A single base change in exon 2 of SLC36A1 was found unique to horses exhibiting Champagne dilution. This change in base 188 of the cDNA from a C to a G (Genbank REFSEQ: Non-champagne EU432176 and Champagne EU432177), is predicted to cause an amino acid change from threonine to arginine in the first transmembrane region. No exceptions to the association of this mutation with the Champagne dilution (CH) allele were identified based on testing 182 additional horses representing 15 breeds, suggesting that this mutation may be the causative for the dilution phenotype. This is the first evidence for a phenotypic effect of mutation of the gene. Identifying this variant also gives breeders a new tool for selecting breeding stock. Extreme lordosis is a condition in which the dorsal to ventral curvature of the back is accentuated. The condition is considered a conformation fault by many Saddlebred breeders and is commonly referred to as swayback, softback or lowback. Previous studies suggested the existence of a hereditary component in American Saddlebred horses. A whole genome association study was performed utilizing the Illumina SNP50 beadchip containing over 59,000 SNPs. A 3 Mb region on ECA20 was found associated with extreme lordosis. The distribution of markers indicated that the trait had a simple Mendelian recessive mode of inheritance. Subsequently, the association was confirmed and the region was narrowed to just over 500 kb by a higher density SNP assay using 47 SNPs selected from the equine SNP database. Identification of this associated region will allow future studies a better opportunity to locate the mutation responsible for the lordotic phenotype in young American Saddlebred Horses.
