연구실 소개
김기원 교수의 연구실은 주로 신경외과 및 재활의학 분야에서 신경기능 모니터링과 운동기능 평가에 초점을 맞추고 있습니다. 특히, 관절 운동량 측정을 위한 비침습적 기기(예: 킷슨)의 임상적 적용과 함께, 척수신경 기능을 실시간으로 평가하는 전기자극 모니터링 기법의 최적화를 연구하고 있습니다. 또한, 뇌종양 제거 수술 중의 신경기능 보존을 위한 내시경적 전기생리학적 모니터링 기술의 발전과 신경독성의 메커니즘 규명에도 기여하고 있습니다.

15Range of motion (ROM) measurements are essential for the evaluation for and diagnosis of adhesive capsulitis of the shoulder (AC). However, taking these measurements using a goniometer is inconvenient and sometimes unreliable. The Kinect (Microsoft, Seattle, WA, USA) is gaining attention as a new motion detecting device that is nonintrusive and easy to implement. This study aimed to apply Kinect to measure shoulder ROM in AC; we evaluated its validity by calculating the agreement of the measurem
The effect of intraarticular hydraulic distension (IHD) for a painful stiff shoulder (or adhesive capsulitis) has been affirmed, but whether rupturing the joint capsule during this process is beneficial remains controversial. By monitoring real-time pressure-volume (PV) profiles during IHD, we could infuse the largest possible volume without rupturing the capsule. Using the novel technique, we compared the short-term effects of IHD when the capsule was preserved versus when it was ruptured. Fift
Intraoperative monitoring (IOM) utilizes electrophysiological techniques as a surrogate test and evaluation of nervous function while a patient is under general anesthesia. They are increasingly used for procedures, both surgical and endovascular, to avoid injury during an operation, examine neurological tissue to guide the surgery, or to test electrophysiological function to allow for more complete resection or corrections. The application of IOM during pediatric brain tumor resections encompas
The outcomes of Neuronox, based on PRS, proved to be as effective and safe as those of BOTOX for the treatment of spasticity in individuals with cerebral palsy.
Intrathecal chemotherapy including methotrexate is well documented for neurotoxicity of diverse clinical manifestation. Acute or chronic leukoencephalopathy is the most common type of methotrexate-induced neurotoxicity, and subacute myelopathy is rare. Although its pathogenesis is not fully understood, it is postulated that direct damage of methotrexate to the central nervous system plays a major part and elevated levels of homocysteine and its excitatory amino acid neurotransmitter metabolites
OBJECTIVE The aim of this study was to establish optimal electric stimulation parameters for intraoperatively monitoring the bulbocavernosus reflexes (BCRs) in infants. METHODS The authors retrospectively reviewed the medical records of all infants (age < 24 months) who had undergone an untethering operation for tethered cord syndrome between May 2013 and February 2014 at a single institution and whose baseline BCR had been elicited during surgery. Using different combinations of stimulation par
Spinal dysraphism often causes neurological impairment from direct involvement of lesions or from cord tethering. The conus medullaris and lumbosacral roots are most vulnerable. Surgical intervention such as untethering surgery is indicated to minimize or prevent further neurological deficits. Because untethering surgery itself imposes risk of neural injury, intraoperative neurophysiological monitoring (IONM) is indicated to help surgeons to be guided during surgery and to improve functional out
Spinal stenosis is a common degenerative condition. However, how neurogenic claudication develops has not been clearly elucidated. Moreover, cerebrospinal fluid physiology at the lumbosacral level has not received adequate attention. This study was conducted to compare cerebrospinal fluid hydrodynamics at the lumbosacral spinal level between patients with spinal stenosis and healthy controls. Twelve subjects (four patients and eight healthy controls; 25-77 years old; seven males) underwent phase
Neurogenic claudication is a typical manifestation of lumbar spinal stenosis (LSS). However, its pathophysiology is still unclear. The severity of clinical symptoms has been shown not to correlate with the degree of structural stenosis. Altered cerebrospinal fluid (CSF) flow has been suggested as one of the causative factors of LSS. The objectives of this study were to compare CSF dynamics at the lumbosacral level between patients with LSS and healthy controls and to investigate whether CSF dyna
A 69-year-old woman complained of severe left leg weakness with paresthesia. Electrodiagnostic tests revealed sciatic neuropathy, and imaging studies showed venous engorgement around the sciatic nerve. After anticoagulant therapy and intensive rehabilitation, the patient's muscle strength improved from 1 to 3 on the Medical Research Council scale. The diagnosis of sciatic neuropathy caused by deep vein thrombosis is extremely rare; however, it should be considered in the differential diagnosis o
Robot-assisted gait training has been investigated for restoring walking through activity-dependent neuroplasticity in persons with various neurologic disorders. This case report presents the outcome of robot-assisted gait training combined with physiotherapy in a 28-year-old man with pure hereditary spastic paraplegia. The patient participated in 25 training sessions over 6 weeks. Improvements were noted in his walking speed and balance after the training, but gait kinematics and kinetics showe
