Objective To identify the differences in the movement of the hyoid bone and the vocal cord with and without electrical stimulation in normal subjects.Methods Two-dimensional motion analysis using a videofluoroscopic swallowing study with and without electrical stimulation was performed. Surface electrical stimulation was applied during swallowing using electrodes placed at three different locations on each subject. All subjects were analyzed three times using the following electrode placements: with one pair of electrodes on the suprahyoid muscles and a second pair on the infrahyoid muscles (SI); with placement of the electrode pairs on only the infrahyoid muscles (IO); and with the electrode pairs placed vertically on the suprahyoid and infrahyoid muscles (SIV).Results The main outcomes of this study demonstrated an initial downward displacement as well as different movements of the hyoid bone with the three electrode placements used for electrical stimulation. The initial positions of the hyoid bone with the SI and IO placements resulted in an inferior and anterior displaced position. During swallowing, the hyoid bone moved in a more superior and less anterior direction, resulting in almost the same peak position compared with no electrical stimulation.Conclusion These results demonstrate that electrical stimulation caused an initial depression of the hyoid bone, which had nearly the same peak position during swallowing. Electrical stimulation during swallowing was not dependent on the position of the electrode on the neck, such as on the infrahyoid or on both the suprahyoid and infrahyoid muscles.

Change of Bone Mineral Density and Relationship to Clinical Parameters in Male Stroke Patients
김휘동,김새현,김동규,정호중,심영주,김기찬 대한재활의학회 2016 Annals of Rehabilitation Medicine Vol.40 No.6
Objective To investigate the clinical characteristics that significantly contribute to a decreased bone mineral density (BMD), the BMD changes and clinical characteristics of men who experienced a stroke between the ages of 50 years and 65 years were studied between 3 months and 4 months after the stroke.Methods Subjects had a brain hemorrhage or a cerebral infarction. Only men aged 50 years to 65 years were included to eliminate postmenopausal osteoporosis and to eliminate the influence of senile osteoporosis. All subjects underwent a BMD test between 3 months and 4 months after their strokes. Also, patients with a medication history that might have caused a secondary osteoporosis before a stroke were excluded. Results The BMD for the lumbar spine and hemiplegic side of the femoral neck correlated significantly with the results of the manual muscle test (MMT) of the hemiplegic lower extremity and the Modified Barthel Index (MBI) score. This result suggests that the immobility from the decreased muscle strength and the weakened daily functionality might have reduced the BMD. According to a multiple linear regression analysis, the MBI score is significantly correlated with the lumbar BMD. The BMD of the hemiplegic femoral neck is significantly correlated with the MMT and the MBI score.Conclusion This study showed that BMD monitoring should be considered in male stroke patients, especially for patients with a high dependency in daily functions and a decreased muscle strength in the hemiplegic lower extremity.

Central Pontine Myelinolysis Induced by Alcohol Withdrawal: A Case Report
김재호,김새현,정호중,심영주,김동규,김기찬 대한재활의학회 2017 Annals of Rehabilitation Medicine Vol.41 No.1
Central pontine myelinolysis (CPM) is a demyelinating disorder characterized by the loss of myelin in the center of the basis pons, and is mainly caused by the rapid correction of hyponatremia. We report the case of a young woman who presented with gait disturbance and alcohol withdrawal, and who was eventually diagnosed with CPM. Generally, the cause and pathogenesis of CPM in chronic alcoholics remain unclear. In this cases, the CPM may be unrelated to hyponatremia or its correction. However, it is possible that the osmotic pressure changes due to refeeding syndrome after alcohol withdrawal was the likely cause in this case. This case illustrates the need for avoiding hasty, and possibly incomplete diagnoses, and performing more intensive test procedures to ensure a correct diagnosis.
