Due to anecdotal reports of back pain during a 12-minute rotational bridge test by uniformed services, the level of fatigue leading to possible back pain and or injury was investigated. We hypothesised a high level of fatigue due to diminishing core muscle activation. Nineteen highly trained uniformed service members were measured by surface electromyography of the rectus abdominis, external oblique, internal oblique, lumbar erector spinae, thoracic erector spinae and latissimus dorsi. Average rectified electromyography amplitude (AEMG) and median power frequency were analysed to determine activation and fatigue...

Background: Several water-based sports (swimming, surfing and stand up paddle boarding) require adequate thoracic mobility (specifically rotation) in order to perform the appropriate activity requirements. The measurement of thoracic spine rotation is problematic for clinicians due to a lack of convenient and reliable measurement techniques. More recently, smartphones have been used to quantify movement in various joints in the body; however, there appears to be a paucity of research using smartphones to assess thoracic spine movement...

PURPOSE: To predict the sagittal spinal parameters as measured in a 3D model of the spine using the 2D radiographic measurements. METHODS: Bi-planar low-dose stereoradiography images of 73 right thoracic AIS patients were processed to generate 3D models of the spine and pelvis. T1-T12 kyphosis, L1-S1 lordosis, and pelvic rotation were calculated using these 3D models. With the same X-rays, T1-T12 kyphosis, L1-S1 lordosis, thoracic and lumbar frontal curves, and pelvic rotation (calculated from the frontal and sagittal distances between the femoral heads) were manually measured on the X-rays by two independent observers...

CASE: A 9-year-old boy sustained intrasubstance tears of the rotator cuff and periscapular muscles due to a fall, resulting in scapular winging and severely decreased shoulder range of motion. Treatment consisted of a modified thoracolumbosacral orthosis (TLSO) with a shoulder immobilizer attachment (to reduce the scapula to the thoracic wall and hold the arm in 10° of abduction). The brace was worn for 8 weeks. The patient recovered full, pain-free shoulder function and range of motion, and returned to high-level athletics...

Various shoulder bone deformities have been identified in the pediatric age group, with the most common being undescended scapula. Sprengel's deformity is dysplasia and malposition of the scapula, especially in the supraspinatus portion, mainly due to abnormal descent in the embryonic period. The clavicle is shorter and has a different contour. In some patients cervical spine deformities are also noted. This is a case of 3 years old girl presented to the clinic with difficulty in abducting right shoulder and sleeping with an internal rotation of the right arm...

The clinical decision for surgical treatment of children diagnosed with mouth breathing depends on the percentage of mechanical obstruction correlated with exacerbation of upper respiratory tract infections and systemic changes. The benefits of adenotonsillectomy include changes in the nasopharyngeal space, the mandibular plane and myofunctional alterations. Post-adenotonsilectomy postural benefits have not yet been described. OBJECTIVES: To investigate the kinematics of the shoulder girdle, cervical and thoracic spine in children with mouth breathing before and after adenotonsillectomy...

Background and Purpose: Secondary impingement syndrome (SIS) is a common complaint in the sporting population particularly among athletes engaging in overhead activities. While symptoms may be present at the shoulder with patients complaining of SIS, spinal alignment or dysfunction can influence scapular positioning and overall shoulder girdle function. As an adjunct therapy to traditional interventions for SIS, thoracic high-velocity low-amplitude (HVLA) thrusts have been utilized and correlated with patient reported decreases in pain...

BACKGROUND: Ponte osteotomy is a useful method in posterior spinal release. However, it is unclear whether Ponte osteotomy itself contributes to vertebral derotation in surgery for adolescent idiopathic scoliosis (AIS) patients compared to inferior facetectomy alone. This study aimed to assess the effect of Ponte osteotomy on the magnitude of periapical vertebral body rotation compared to inferior facetectomy alone. This study was a prospective collected data. METHODS: The study included 63 patients with AIS (Thoracic curve type, 35; thoracolumbar/lumbar curve type, 27), who underwent surgery between August 2011 and January 2015...
