[Purpose] The aim of this study was to investigate the effects of dynamic sitting exercises during prolonged sitting on the lower back mobility of sedentary young adults. [Subjects and Methods] Seventy-one subjects aged between 18-25 years participated in this study. Following a randomized crossover study design, subjects were randomly assigned to two groups: sitting only and dynamic sitting ex...

BACKGROUND Previous epidemiological studies have observed that an initial head restraint backset greater than 10 cm is associated with a higher risk of neck injury and persistent symptoms. The objective of this study was to investigate the relation between the active head restraint position and peak neck motion using a new human model of the neck. METHODS The model consisted of an osteoligame...

We describe a patient with traumatic right-sided invagination of two consecutive laminae into the spinal canal. The injury resembled a greenstick fracture and resulted in an acute Brown-Sequard syndrome. There was also an undisplaced hangman's fracture of the axis vertebra. These injuries were caused by an acute hyperextension and axial compression of the cervical spine. Open reduction and inte...

Spondylolysis is a condition seen in approximately 6-8 % of the population [1]. It involves a defect in the pars interarticularis precipitated by repeated low grade trauma resulting in a stress fracture. The defect is occupied by fibrocartilagenous tissue resulting in non-union [2]. The prevalance is higher among athletes regularly performig hyperextension and rotation activities to the lumbar ...

Spinal cord injury without radiographic abnormality (SCIWORA) is associated with self-reducing transient subluxation or distraction of the juvenile spine. It accounts for about 40% of spinal injuries in children under sixteen. Children's anatomical features increase their susceptibility to hyperflexion, hyperextension and distraction mechanisms. Nursing management includes an awareness of two o...

A procedure is described for reconstruction of the oblique retinacular ligament using a small tendon graft in a spiral fashion to act as a dynamic tenodesis to restore distal interphalangeal extension and to restrain proximal interphalangeal hyperextension. The method has been uniformly successful in the treatment of post-traumatic "swan-neck" or "mallet" deformity. Although the concept is simp...

CASE REPORT A thirteen year old boy (at the 80th percentile for height and weight) was weight-lifting, alone, in a makeshift gymnasium at his parents' house. As he approached the apex of a lift, the barbell weighing 30 kg passed posterior to his centre of gravity and began to pull him over backwards. In attempting to retrieve the situation he felt the sudden onset of pain in both wrists as they...

Spinal cord injury is a well recognized obstetrical complication of fetal hyperextension. It is most often seen in breech deliveries but is also found approximately 25% of the time in cephalic presentations. Myelography and CT have been the primary imaging methods used to demonstrate the cord defect. This case report describes the use of MR imaging in the evaluation of suspected avulsion of the...

PURPOSE Multiple sclerosis (MS) manifests itself in a wide range of symptoms. Physiotherapy plays an important role in the treatment of those symptoms connected with mobility. For this therapy to be at its most effective it should be based on a systematic examination that is able to describe and classify damaged clinical functions meaningfully. The purpose of this study was to develop and valid...

The aim of this study was to assess the effect of conservative versus operative treatment for unstable palmar plate disruption in the proximal interphalangeal (PIP) joint of the fingers with respect to preservation of joint stability, mobility, and pain. The study was conducted as a prospective study in which 83 patients were randomly assigned into 2 groups: (1) conservative treatment with a ri...
