The criteria for the evaluation of spinal impairment are diverse, complex, and have no standardized form. This makes it difficult and somewhat troublesome to accurately evaluate spinal impairment patients. A standardized guideline was studied for the evaluation of spinal impairment, based on the American Medical Association (AMA) Guides and the McBride method. This guideline proposal was developed by specialty medical societies under the Korean Academy of Medical Sciences. In this study, the grades of impairment were assessed by dividing patients into three different categories: spinal cord impairment, spinal injury impairment and spinal disorder impairment. The affected regions of the spine are divided into three: the cervical region, the thoracic region, and the lumbosacral region. The grade of impairment was differentially evaluated according to the affected region. The restricted range of motion was excluded in the evaluation spinal impairment because of low objectivity. Even though the new Korean guideline for the evaluation of spinal impairment has been proposed, it should be continuously supplemented and revised.

STUDY DESIGN: To determine the capability to predict the clinical manifestations and treatment outcomes of traumatic cervicothoracic cord injury patients based on MR images. OBJECTIVE: To determine the relationship between the differences in MR patterns and signal areas according to Maravilla and Cohen's classification and the PACS system compared with the Frankel classification, in patients that demonstrated neurologic improvement within 1 year. SUMMARY OF LITERATURE REVIEW: MR is the first imaging modality that directly visualizes the extent of spinal cord derangement, and thus, it has the potential to provide an accurate diagnosis of an injury and to determine the prognosis. MATERIALS AND METHODS: MR images were evaluated within 3 days of trauma in 36 spinal cord injury patients. The clinical follow-up period was more than 1 year. Quantitative analysis of spinal cord lesions was performed according to the PACS system. RESULTS: According to Maravilla and Cohen's classification, 36 cases were classified as follows: 8 cases of type I, 10 cases of type II, 9 cases of type III and 9 cases of type IV. There was 1 case of type I, 8 cases of type II, 5 cases of type III, and no cases of type IV, who demonstrated neurologic improvements of more than 1 grade in the Frankel classification. An analysis of the signal areas according to the PACS system demonstrated no cases of areas greater than 100 mm2, 5 cases of areas between 50 to 100 mm2, and 9 cases of areas less than 50 mm2 who demonstrated neurologic improvement. CONCLUSION: Classification according to the differences between MR imaging and MRI signal areas in patients with spinal cord injuries demonstrated the indicators of neurologic improvement; therefore, we MR imaging can be utilized as a prognostic factor in cases of spinal cord injuries.

BACKGROUND: Rehabilitations in subacute phase are different from acute treatments regarding the characteristics and required resource consumption of the treatments. Lack of accuracy and validity of the Korean Diagnosis Related Group and Korean Out-Patient Group for the acute patients as the case-mix and payment tool for rehabilitation inpatients have been problematic issues. The objective of the study was to develop the Korean Rehabilitation Patient Group (KRPG) reflecting the characteristics of rehabilitation inpatients. METHODS: As a retrospective medical record survey regarding rehabilitation inpatients, 4,207 episodes were collected through 42 hospitals. Considering the opinions of clinical experts and the decision-tree analysis, the variables for the KRPG system demonstrating the characteristics of rehabilitation inpatients were derived, and the splitting standards of the relevant variables were also set. Using the derived variables, we have drawn the rehabilitation inpatient classification model reflecting the clinical situation of Korea. The performance evaluation was conducted on the KRPG system. RESULTS: The KRPG was targeted at the inpatients with brain or spinal cord injury. The etiologic disease, functional status (cognitive function, activity of daily living, muscle strength, spasticity, level and grade of spinal cord injury), and the patient's age were the variables in the rehabilitation patients. The algorithm of KRPG system after applying the derived variables and total 204 rehabilitation patient groups were developed. The KRPG explained 11.8% of variance in charge for rehabilitation inpatients. It also explained 13.8% of variance in length of stay for them. CONCLUSION: The KRPG version 1.0 reflecting the clinical characteristics of rehabilitation inpatients was classified as 204 groups.

INTRODUCTIONThe aim of this study was to assess the sensitivity of McDonald's magnetic resonance imaging (MRI) criteria for the diagnosis of multiple sclerosis (MS) in a group of Asian patients diagnosed with clinically definite MS, based on lesion characterisation on MRI scans.
MATERIALS AND METHODSForty-nine patients from 3 major neurological institutions were classified as having Asian- or Western-type MS based on clinical assessment. Each MRI scan was reviewed by 2 neuroradiologists for the presence and characteristics of brain and spinal lesions. The McDonald's MRI criteria were then applied and its sensitivity evaluated.
RESULTSNine patients were excluded, leaving 34 females and 6 males who were dominantly Chinese (90%), with a mean age of 36.2 years. The MRI brain and spinal findings were detailed and tabulated. Statistically significant differences (P <0.01) in MRI brain findings and sensitivity of McDonald's MRI criteria were found between our Asian- and Western-type MS patients. The diagnostic yield of McDonald's MRI criteria increased by 20% when we substituted a cord for a brain lesion, and applied the substitution for enhancing cord lesions as well.
CONCLUSIONThe diagnosis is more likely to be made when using McDonald MRI criteria based on brain findings, in a patient who presents clinically with Western-type MS. The provision for substitution of "one brain for a spinal lesion" is helpful in Asian-type MS, where there is preponderance of spinal lesion load. Our findings suggest that minor modifications in the interpretation of McDonald's MRI criteria have significant impact on the diagnosis in patients clinically presenting as Asian-type MS, with potential bearing on their subsequent management.
