[Purpose] The purpose of this study was to investigate the effects of thoracic extension exercise on scapular alignment and thoracic kyphosis angle. [Subjects and Methods] Ten subjects with a kyphosis angle ≥40° and aged between 20 and 26 years participated in this study. This study investigated the scapular forward distance and thoracic kyphosis angle before and after the thoracic extension ex...

BACKGROUND Scheuermann's disease is regarded as the most common cause of structural hyperkyphosis within adolescents without any proper treatment. It may lead to progressive deformity and back pain which influences patient's quality of life during adolescence and adulthood. Treatment approach to Scheuermann's kyphosis has not been clearly defined due to its different definitions and obscure nat...

Muscle fibers attach to laminin in the basal lamina using two distinct mechanisms: the dystrophin glycoprotein complex and the alpha 7 beta 1 integrin. Defects in these linkage systems result in Duchenne muscular dystrophy (DMD), alpha 2 laminin congenital muscular dystrophy, sarcoglycan-related muscular dystrophy, and alpha 7 integrin congenital muscular dystrophy. Therefore, the molecular con...

abstract objective: to present the changes in projected thoracic hypokyphosis and the behavior of lumbar lordosis within and below the fusion and to compare these changes between the harrington rod (hr) and posterior multisegmented hook instrumentation. methods: 178 patients with idiopathic scoliosis, who had undergone posterior spinal fusion with harrington technique (106 patients) or multiseg...

the purpose of this study was to examine the effect of eight weeks corrective games on kyphosis angle and postural control in kyphotic mentally retarded children. method: thirty mentally retarded girls children with increase normal thoracic kyphosis (kyphosis angle≥40) were selected and randomly divided in two groups training group (n=15 with mean average 12/06±2/8 years old, height 145±1/33cm,...

Structural kyphosis is a posterior convex deformity of the spine that may appear in childhood then worsen with growth, most notably during the pubertal growth spurt. The abnormal curvature may be smooth, defining round kyphosis, or may display a sharp angular pattern. Angular kyphosis is the more severe of the two forms. The main causes of round kyphosis are postural kyphosis and Scheuermann's ...

To better understand the biomechanical mechanisms underlying the association between hyperkyphosis of the thoracic spine and risk of vertebral fracture and other degenerative spinal pathology, we used a previously validated musculoskeletal model of the spine to determine how thoracic kyphosis angle and spinal posture affect vertebral compressive loading. We simulated an age-related increase in ...

We reviewed 26 patients with progressive spinal kyphosis due to anterior fusion between the vertebrae. No patient had back pain or any neurological defect. The kyphosis appeared to be progressive until the fusion had included all of the disc. Progression was faster during the adolescent growth-spurt. Kyphosis increased with the number of discs involved, from one to six, and the extent of fusion...
