Iodine-123-labelled iodoamphetamine single-photon emission computed tomography of patients with reflex sympathetic dystrophy syndrome showed substantial variation in thalamic perfusion of the side contralateral to the painful limb. The variations are related to time from the onset of symptoms, which suggests that the thalamus undergoes adaptive changes in(More)
BACKGROUND This cross-sectional study was conducted to obtain epidemiologic data on chronic musculoskeletal pain in the Japanese people, and with it a better understanding of the actual conditions and problems involved. METHODS A questionnaire covering basic information, chronic musculoskeletal pain, daily life, quality of life, and social loss was(More)
STUDY DESIGN A retrospective clinical study was conducted. OBJECTIVE To investigate the relative safety of anterior microsurgical decompression with iliac strut graft fusion versus laminoplasty for a massive ossified posterior longitudinal ligament in the cervical spine. SUMMARY OF BACKGROUND DATA The question of how the treatment for cervical(More)
The authors present clinical, radiological, and pathological features of the “widespread” type of primary spinal oligodendroglioma arising in a 12-year-old boy. The initial symptoms were gait disturbance, hypesthesia of the lower trunk, and scoliosis. Gadolinium-enhanced magnetic resonance imaging revealed an intramedullary tumor with syringomyelia. The(More)
BACKGROUND Degenerative spondylolisthesis of the cervical spine has received insufficient attention in contrast to that of the lumbar spine. The authors analyzed the functional significance of anterior and posterior degenerative spondylolisthesis (anterolisthesis and retrolisthesis) of the cervical spine to elucidate its role in the development of cervical(More)
We treated 31 patients aged 65 years or more with cervical spondylotic myelopathy by microsurgical decompression and fusion at a single most appropriate level, in spite of MRI evidence of compression at several levels. Spinal cord potentials evoked at operation localised the level responsible for the principal lesion at C3-4 in 18 patients, C4-5 in 11 and(More)
BACKGROUND Premedication with sedatives can decrease the discomfort associated with invasive anesthetic procedures. Some researchers have shown that acupressure on the acupuncture extra 1 point is effective for sedation. We investigated whether acupressure on the extra 1 point could alleviate the pain of needle insertion. METHODS We investigated the(More)
STUDY DESIGN A correlation was studied between degenerative spondylolisthesis (DSL) of the cervical spine and spinal-evoked potentials intraoperatively recorded in elderly patients who had surgical treatment for cervical spondylotic myelopathy. OBJECTIVE To investigate the functional importance of cervical DSL in elderly patients with cervical spondylotic(More)
Painful neuropathic conditions of cancer pain often show little response to nonopioid and opioid analgesics but may be eased by antidepressants and anticonvulsants. Although gabapentin is effective in the treatment of neuropathic pain in patients with cancer, some patients experience intolerable side effects sufficient to warrant discontinuation. The aim of(More)
In the management of clinical low back pain (LBP), actual damage to lower back areas such as muscles, intervertebral discs etc. are normally targeted for therapy. However, LBP may involve not only sensory pain, but also underlying affective pain which may also play an important role overall in painful events. Therefore we hypothesized that visualization of(More)
