UNLABELLED Benign Paroxysmal Positional Vertigo is the most common peripheral vestibular disorder, especially in the elderly and presents as the predominant etiology in this population of the degeneration of the utricular macula. AIM To compare the effectiveness of the approaches after Epley maneuver. STUDY DESIGN longitudinal cohort. MATERIALS AND METHODS The study included 53 volunteers...

Neck and back pain is one of the most common musculoskeletal complaints in personnel in variable acceleration environments such as astronauts and military pilots. Ultrasound is known for dynamic imaging and diagnostic workup of the axial and appendicular skeleton, but is not currently used to image the cervical spine, the injury of which may change the biomechanics of the cervical vertebrae, wh...

rauma to the vertebral column is relatively uncommon in the pediatric patient population. It accounts for approximately 5% of all spinal cord and vertebral column injuries.1 In the patient with an immature spine (0-9 years) the majority of spinal injuries occur at the cervical (C) spine, especially between the occiput and C2.2,3 When diagnosed and managed properly, most of these injuries can be...

Intervertebral disc herniation (IVDH) with nucleus pulposus extrusion, traumatic or not, is a devastating clinical condition accompanied by neurological problems. Here we report a cynomolgus macaque suffering from acute and progressive neurological dysfunction by a blunt trauma due to neck collar, an animal handling device. Tetraplegia, urinary incontinence, decreased proprioception, and imperc...

Spinal immobilization is one of the most commonly performed pre-hospital procedures. Little research has been done on the movement of the neck during immobilization and extrication. In this study we used a sophisticated infrared six-camera motion-capture system (Motion Analysis Corporation, Santa Rosa, CA), to study the motion of the neck and head during extrication. A mock automobile was const...

Thirteen patients with fractures and/or dislocations of the middle and lower cervical spine were treated by transpedicular screw fixation using the Steffee variable screw placement system. Postoperative immobilization was either not used or simplified to short-term use of a soft neck collar. Recovery of nerve function and correction of kyphotic and/or translational deformities were satisfactory...

Hirayama disease (juvenile muscular atrophy of distal upper extremity) is a cervical myelopathy predominantly affecting adolescent males. It is characterized by progressive muscular weakness and atrophy of unilateral or asymmetrically bilateral distal upper limbs. We report a case of an 18-year-male painter, who presented with gradually progressive, symmetrical bilateral weakness of hands and f...

OBJECTIVE While chronic cerebrospinal venous insufficiency (CCSVI) can be characterized using cervical plethysmography, much remains unknown about the haemodynamics associated with this procedure. The aim of the study was therefore to gain a deeper understanding of the observed haemodynamics. METHOD Forty healthy controls and 44 CCSVI patients underwent cervical plethysmography, which involve...
