Cervical pedicle screw has been shown to provide stronger fixation than other methods. Due to these virtue of biomechanical characteristic, pedicle screw fixation can be used in a wide range of cervical spinal disorders, and excellent clinical results have been reported. However, this procedure is technically demanding because of the great variation in pedicle dimension and angulations between ...

Constant drive provided to the human lumbar spinal cord by epidural electrical stimulation can cause local neural circuits to generate rhythmic motor outputs to lower limb muscles in people paralysed by spinal cord injury. Epidural spinal cord stimulation thus allows the study of spinal rhythm and pattern generating circuits without their configuration by volitional motor tasks or task-specific...

the subjective of this study was to explore and compare the effects of whole body vibration (wbv) and conventional spinal stabilization exercises on persons with non-specific chronic low back pain (clbp). thirty patients with non-specific chronic low back pain randomly received 6 sessions of spinal stabilization therapy with and without whole body vibration over 2 weeks. the severity of pain, f...

Following peripheral nerve sections some locomotor deficits appear which are gradually compensated for by spinal and supraspinal mechanisms. The present work is aimed at identifying contributions of both types of mechanisms. We performed a denervation of the left lateral gastrocnemius-soleus (LGS) muscles in three cats which was followed by a spinalization at the 13th thoracic segment. Three ot...

Introduction: Effect of tripolar TENS of vertebral column on slow and fast motoneurons (MNs) activity of soleus muscle was previously investigated. In this study for better differentiation of the behavior of slow and fast MNs, we exploited H-reflex recovery curve recording in two muscles of soleus and lateral gastrocnemius, respectively as the representatives of slow and fast muscles. Meth...

Copyright © 2009 by the Congress of Neurological Surgeons Benign and malignant tumors of the spinal column and spinal cord are a common and costly clinical problem, causing significant morbidity. Metastatic disease to the spine is the most common presentation; approximately 160 000 new spinal metastases are diagnosed in the United States each year, resulting in considerable pain, functional imp...

In adult male rats, motoneurons of the spinal nucleus of the bulbocavernosus (SNB) have been shown to retract and reextend their dendritic branches in response to systemic androgen deprivation and readministration. Furthermore, other studies have suggested that the dendritic complexity of neurons can be regulated by their targets. To assess whether androgens might act upon the target muscles to...

BACKGROUND AND PURPOSE Slumped sitting is known to increase disc pressure and aggravate chronic low back pain. In addition, it has been recognized that co-contraction of the deep spine-stabilizing muscles enhances lumbar segmental stability and the sacro-iliac joint. The purpose of this study was to compare the electromyographic (EMG) activity of the trunk muscles and the muscle thickness of th...

The suboccipital muscles are connected to the upper cervical spinal dura mater via the myodural bridges (MDBs). Recently, it was suggested that they might work as a pump to provide power for cerebrospinal fluid (CSF) circulation. The purpose of this study was to investigate effects of the suboccipital muscles contractions on the CSF flow. Forty healthy adult volunteers were subjected to cine ph...
