BACKGROUND In patients with structural idiopathic scoliosis the body asymmetries involve the pelvis and the lower limbs; they are included in many theories debating the pathogenesis of idiopathic scoliosis. METHODS Hip joint range of motion was studied in 158 adolescent girls, aged 10-18 years (mean 14.2 +/- 2.0) with structural idiopathic scoliosis of 20-83 degrees of Cobb angle (mean 43.0 d...

In this paper we present an algorithm for estimating the rotation index of a closed regular intersection curve from its singular points. On the basis of this index we have also devised a procedure that guarantees that a closed intersection curve will be traced completely, without overlapping. Combining this procedure with marching steps derived from differential geometric properties has resulte...

OBJECTIVE To investigate the reliability and diagnostic accuracy of individual tests and combination of tests for subacromial impingement syndrome (SAIS). DESIGN A prospective, blinded study design. SETTING Orthopedic surgeon shoulder clinic. PARTICIPANTS Patients with shoulder pain (n=55, mean age=40.6y). INTERVENTIONS Patients were evaluated with 5 physical examination tests for SAIS:...

We present an analysis of high resolution HI data of the dwarf galaxy DDO 47, aimed at testing the hypothesis that dark halo triaxiality might induce non-circular motions resulting in rotation curves best fitted by cored halos, even if the dark matter halo is intrinsically cuspy. This hypothesis has been invoked in order to reconcile the predictions of the ΛCDM theory with the rotation curves o...

Methods A total of 6824 children (3477 boys and 3347girls) aged from 6 to 17 years old recruited from 352 classes of primary schools, and junior and senior high schools were screened for scoliosis. 442 children showed physical signs of potential scoliosis (Angle of Trunk Rotation at Adam’s forward bending test of five degrees or more) and were referred for posteroanterior radiographic evaluatio...
