Purpose: This study was accomplished to investigate the electromyographic activity of 3 plyometric exercises (tuck jump and single leg hop in sagittal and frontal planes) to find out the appropriate procedures for strengthening biceps femoris and gluteus medius muscles. Methods: The kind of study is applied and data were collected from the supervised exercises of 15 male athletes without i...

The purpose of this study was to determine whether 5-mm axial CT images can sufficiently depict the hyperdense middle cerebral artery (MCA) sign in patients with acute brain ischemia. Materials and Methods: A retrospective review of 92 cases of ischemic brain infarction confirmed nine patients showing hyperdense MCA signs. CT images were acquired on a 64-slice helical scanner. Images were recon...

OBJECTIVES To determine the range of positions of the fetal head in which a three-dimensional (3D) volume is acquired for subsequent successful imaging of the corpus callosum. METHODS We used 3D volumes of the fetal head obtained from singleton pregnancies at 20 to 23 + 6 weeks' gestation. The volumes, which had been acquired with the head in different positions, were then reconstructed with ...

BACKGROUND Fixed sagittal imbalance (a syndrome in which the patient is only able to stand with the weight-bearing line in front of the sacrum) has many etiologies. The most commonly reported technique for correction is the Smith-Petersen osteotomy. Few reports on pedicle subtraction procedures (resection of the posterior elements, pedicles, and vertebral body through a posterior approach) are ...

OBJECTIVES The objective of this study was to assess the association between whole body sagittal balance and risk of falls in elderly patients who have sought treatment for back pain. Balanced spinal sagittal alignment is known to be important for the prevention of falls. However, spinal sagittal imbalance can be markedly compensated by the lower extremities, and whole body sagittal balance inc...

Background: The majority of total ankle arthroplasty (TAA) systems use extramedullary alignment guides for tibial component placement. However, at least 1 system offers intramedullary referencing. In total knee arthroplasty, studies suggest that tibial component placement is more accurate with intramedullary referencing. The purpose of this study was to compare the accuracy of extramedullary re...

AIMS The aim of the present study was to evaluate test-retest measurements of functional aspects of pelvic floor muscle (PFM) contraction using four dimensional (4D) ultrasound. METHODS Seventeen females preformed three maximal PFM contractions in standing, recorded by 4D real time ultrasound, on two separate occasions. RESULTS Very good and good reliability was fond for measurement of: Lev...

Axial computed tomographic (CT) images were compared with sagittal and coronal reformations and myelograms in 60 patients to evaluate the diagnostic usefulness of multiplanar reconstructions for the recognition of lumbar disk disease. The axial CT scans were most sensitive and specific. The sagittal scans were helpful in evaluating the neural foramina, the size of the disk bulge into the spinal...
