STUDY DESIGN Prospective randomized controlled study. OBJECTIVE To compare the outcome of indirect decompression by means of the X-Stop (Medtronics Inc., Minneapolis, MN) implant with conventional decompression in patients with neurogenic intermittent claudication due to lumbar spinal stenosis. SUMMARY OF BACKGROUND DATA Decompression is currently the(More)
Postural equilibrium has been quantified by stabilometry in 57 patients with adolescent idiopathic scoliosis aged 10-16 years. Treatment was required in 39 cases whereof 18 were placed under observation only. The control group comprised 32 healthy children of the same age. An experimental design was made to vary the degree of difficulty of upright standing(More)
An EEG study was carried out on 57 children, aged 10--16 years, with idiopathic scoliosis. Treatment (brace or surgery) was required in 37 cases; 20 were being observed only. Controls were 10- to 16-year-old healthy children meeting well-defined criteria of normality. Thirty-four of the scoliotics fulfilled these criteria, thus providing a group matching(More)
Postural sway has been quantified with stabilometry during caloric labyrinthine stimulation in an erect posture in 49 patients, aged 10--16 years, with adolescent idiopathic scoliosis. Thirty-two healthy children of the same age constituted a control group. The scoliotic patients tended to have an increased postural sway during labyrinthine stimulation on(More)
An analysis of the diagnostic reliability and the clinical value of moiré topography is presented. Moiré topography was used as an adjunct to clinical assessment and roentgenographic examination in a consecutive series of 139 scoliosis observations. In 17%, the moiré pattern lateral to the scapulae was impossible to analyze. One false negative finding and(More)
An analysis of lateral predominance of 51 patients with adolescent idiopathic scoliosis is presented. Determination of handedness, the dominant foot, and the dominant eye was performed. Postural equilibrium was studied by stabilometry, and the vestibular function was evaluated with electronystagmography. Central and peripheral nervous function were(More)
An electro-nystagmographic study of labyrinthine function was performed in 56 patients with adolescent idiopathic scoliosis (AIS)aged from 10 to 16 years. Forty-seven patients had major structural single curvatures, and nine patients had double-primary scoliosis and were analysed separately. Treatment was required in 36 cases while 20 were being observed(More)
Measurements of nerve conduction velocity (NCV) in the peroneal and median nerves have been performed in 47 patients with adolescent idiopathic scoliosis (AIS). The results did not reveal any pathology neither asymmetries correlated to convexity of scoliosis. Patients requiring treatment showed significantly lower sensory nerve conduction velocity of median(More)
The etiologic importance of postural dysfunction, as shown by many authors in adolescent idiopathic scoliosis (AIS), has been under great debate. The authors' hypothesis was that a factor that is involved in the development of the scoliotic curvature, would be present also in nonscoliotic siblings to scoliosis patients, as AIS is a hereditary transmitted(More)
Postural equilibrium factors were evaluated as indicators of the prognosis in 52 patients with adolescent idiopathic scoliosis. The hypothesis was that dysfunction in these equilibrium factors might imply a higher risk for the curve to progress. The postural equilibrium was studied by stabilometry, and the function of the central nervous system was assessed(More)
