OBJECT The aim of this study was to analyze the mechanism and prognostic factors of foot drop caused by lumbar degenerative conditions. METHODS The authors retrospectively reviewed the charts of 28 patients with foot drop due to a herniated nucleus pulposus (HNP) or lumbar spinal stenosis (LSS), scoring between 0 and 3 on manual muscle testing for the(More)
OBJECT In this study the authors investigated the neck pain of patients with cervical myelopathy by using a visual analog scale (VAS) before and after laminoplasty, and they analyzed the association of amount of neck pain with the clinical results. METHODS A retrospective review was conducted in 41 patients with cervical myelopathy who underwent cervical(More)
Spinocerebellar ataxia type 1 (SCA1) is a devastating neurodegenerative disorder in which an abnormally expanded polyglutamine tract is inserted into causative ataxin-1 proteins. We have previously shown that SCA1 knockin (SCA1-KI) mice over 6 months of age exhibit a degeneration of motor neuron axons and their encasing myelin sheaths, as reported in SCA1(More)
OBJECT The goal of this study was to investigate the relationship between preservation of the insertion of the deep extensor musculature of the cervical spine at C-2 and postoperative cervical alignment, especially differences between cases involving male and female patients, as well as the relationship between the loss of cervical lordosis and neurological(More)
BACKGROUND Neck and shoulder pain (NSP), called katakori in Japanese, is one of the most common medical symptoms in the Japanese population; however, the pathogenesis of NSP has not yet been adequately elucidated. The purpose of this study was to investigate the associations between NSP and sagittal spinal alignment among the general population in Japan. (More)
BACKGROUND It seems to be important to recognize predictors of bone health condition in Japanese super-aged society. The purpose of this study was to investigate predictors of the speed of sound (SOS) of calcaneus by quantitative ultrasound measurements of mountain village residents. MATERIALS AND METHODS Medical examinations were conducted on 214(More)
Although shoulder apprehension is an established clinical finding and is important for the prevention of shoulder dislocation, how this subjective perception is evoked remains unclear.

Congenital scoliosis is a condition characterized by spinal curvature beyond the physiological norm. The molecular mechanisms underlying the pathogenesis of congenital scoliosis are beginning to be clarified; however, the genes related to congenital scoliosis are still unknown. We herein report the results of a comprehensive analysis of gene expression in(More)
INTRODUCTION Schwannoma is a relatively common benign spinal cord and/or cauda equina tumor; however, giant cauda equina schwannoma with extensive scalloping of the lumbar vertebral body is a rare pathology, and the treatment strategy, including the use of surgical procedures, is controversial.
