To evaluate the effectiveness of the human umbilical cord blood (HUCB) transplantation for the treatment of intrinsic sphincter deficiency (ISD), we analyzed the short term effects of HUCB mononuclear cell transplantation in rats with induced-ISD. ISD was induced in rats by electro-cauterization of periurethral soft tissue with HUCB mononuclear cell injection after 1 week. The sphincter function measured by mean leak point pressure was significantly improved in the experimental group compared to the control group at 4 weeks. (91.75+/-18.99 mmHg vs. 65.02+/-22.09 mmHg, P=0.001). Histologically, the sphincter muscle was restored without damage while in the control group it appeared markedly disrupted with atrophic muscle layers and collagen deposit. We identified injected HUCB cells in the tissue sections by Di-I signal and Prussian blue staining. HUCB mononuclear cell injection significantly improved urethral sphincter function, suggesting its potential efficacy in the treatment of ISD.

OBJECTIVE: To evaluate the effect of multiple sensory stimulation on cortical excitability by using transcranial magnetic stimulation (TMS). METHOD: Thirteen right handed young adults without neurological deficit were enrolled. Cortical excitability was tested by measuring recruitment of motor evoked potentials [recruitment curve (RC)], intracortical inhibition (ICI), and intracortical facilitation (ICF) at the abductor pollicis brevis of the dominant hand in two different conditions: (1) group A: active thumb and index finger pinch movement while observing the congruent finger movement in a screen with 0.2 Hz bell sound for 30 minutes, (2) group B: the same active finger movement in a dark screen with the same bell sound for 30 minutes. All of these procedures were done with a randomized crossover design. RESULTS: The amplitude of MEP and the slope of all RC (140%,160% of the resting motor threshold) of group A showed increment after visually-guided finger movement and the level of ICI showed decrement after visually guided finger movement (p<0.05), but there was no change in the level of ICF (p>0.05) in group A. In group B, the amplitude of MEP and the levels of ICI, ICF showed no significant changes following finger movement with no visual guidance (p>0.05), but the slope of RC with 140% showed increment (p<0.05). CONCLUSION: These findings suggest that cortical excitability can be enhanced by simple repetitive motor practice. The congruent sensori-motor stimulations lead to corresponding additional effect on cortical excitability, presumably by recruitment of remote motor neurons.

The thalamus, located between the cerebrum and midbrain, is a nuclear complex connected to the cerebral cortex that influences motor skills, cognition, and mood. The thalamus is composed of 50-60 nuclei and can be divided into four areas according to vascular supply. In addition, it can be divided into five areas according to function. Many studies have reported on a thalamic infarction causing motor or sensory changes, but few have reported on behavioral and executive aspects of the ophthalmoplegia of the thalamus. This study reports a rare case of a paramedian thalamus infarction affecting the dorsomedial area of the thalamus, manifesting as oculomotor nerve palsy, an abnormal behavioral change, and executive dysfunction. This special case is presented with a review of the anatomical basis and function of the thalamus.

OBJECTIVE: The objective of present study was to identify the rehabilitation outcome measures currently used in Korea. METHOD: The survey was conducted by e-mail questionnaire to 165 department of rehabilitation medicine in hospitals of Korea. Non-responders were sent a second copy of the questionnaire if they did not answer within 1 week. Data from the returned questionnaires were entered into a Microsoft Excel and subjected to descriptive and simple quantitative analysis. RESULTS: A total of 99 (60%) responses were received. Of these, 95% units collected some outcome assessment measure as part of routine clinical practice. Korean version of Modified Barthel Index (K-MBI) (80%) was the most popular global outcome measures. The Korean version of Berg Balance Scale (K-BBS) (53%) was used most frequently for balance assessment. Upper extremity function was checked with hand grip strength test (70%) and Box and block test (67%) most commonly. Korean version of Mini Mental State Examination (K-MMSE) was the most popular cognitive function test (75%). PARADISE Korean version-Western Aphasia Battery (PARADISE K-WAB) was the most popular language test (67%). Sixty-three (67%) units used outcome results for discussion and goal setting. Seventy-eight (78%) units responded that they would use a standardized outcome measures if there is an agreed standardized outcome measures lists (80%) and support of money and time (43%). CONCLUSION: The survey demonstrated that quite widespread use of outcome assessments in routine clinical rehabilitation within Korea. There is also an agreement for need of common 'basket' of recommended instruments for rehabilitation.

OBJECTIVE: To determine the validity and reliability of the Korean version of the Coma Recovery Scale-Revised (K-CRSR) for evaluation of patients with a severe brain lesion. METHODS: With permission from Giacino, the developer of the Coma Recovery Scale Revised (CRSR), the scale was translated into Korean and back-translated into English by a Korean physiatrist highly proficient in English, and then verified by the original developer. Adult patients with a severe brain lesion following traumatic brain injury, stroke, or hypoxic brain injury were examined. To assess the inter-rater reliability, all patients were tested with K-CRSR by two physiatrists individually. To determine intra-rater reliability, the same test was re-administered by the same physiatrists after three days. RESULTS: Inter-rater reliability (k=0.929, p < 0.01) and intra-rater reliability (k=0.938, p < 0.01) were both high for total K-CRSR scores. Inter- and intra-rater agreement rates were very high (94.9% and 97.4%, respectively). The total K-CRSR score was significantly correlated with K-GCS (r=0.894, p < 0.01), demonstrating sufficient concurrent validity. CONCLUSION: K-CRSR is a reliable and valid instrument for the assessment of patients with brain injury by trained physiatrists. This scale is useful in differentiating patients in minimally conscious state from those in vegetative state.

OBJECTIVE: To follow up the long-term functioning in a community through assessing personal background and status based on the International Classification of Functioning, Disability and Health (ICF) after a stroke, by using a Korean version of World Health Organization Disability Assessment Scale II (K-WHODAS II). METHODS: We surveyed 146 patients diagnosed at the first-onset of acute stroke and discharged after Inha University Hospital, and 101 patients answered the K-WHODAS II survey. We analyzed the relationship of six functioning domains of K-WHODAS II with K-MMSE (Korean version of Mini-Mental State Examination) and K-MBI (Korean version of Modified Barthel Index) at admission and discharge, and personal background. All subjects were divided into five groups, according to the disease durations, to assess the functional changes and the differences of K-MMSE and K-MBI at the admission and discharge. RESULTS: K-MBI and K-MMSE at admission and discharge showed no significant differences in all five groups, respectively (p>0.05), reflecting no baseline disparity for long-term follow-up. All subjects showed positive gains of K-MBI and K-MMSE at discharge (p<0.05). The six functioning domains and total scores of K-WHODAS II had decreasing trends until 3 years after the stroke onset, but rose thereafter. Higher scores of K-MBI and K-MMSE, younger age, women, working status, higher educational level, and living with a partner were correlated with lower scores of K-WHODAS II (p<0.05). CONCLUSION: The long-term functioning after stroke was affected not only by cognitive and motor status in hospital, but also by certain kinds of personal background. K-WHODAS II may be used to monitor functioning status in a community and to assess personal backgrounds in subjects with chronic stroke.

OBJECTIVE: To evaluate effects of caregiver's education program on their satisfaction, as well as patient functional recovery, performed in addition to daily conventional rehabilitation treatment. METHODS: Three hundred eleven subjects diagnosed with first-onset stroke and transferred to the Department of Physical Medicine and Rehabilitation of Inha University Hospital were surveyed. In 2015, caregivers attended an education program for acute and subacute stroke patients. Patients who received an additional rehabilitation therapy were assigned to the experimental group (n=81), whereas the control group (n=100) consisted of transfer cases in 2014 with only conventional treatment. The experimental group was classified by severity using the Korean version of the National Institutes of Health Stroke Scale (K-NIHSS), which was administered to all 181 subjects, in addition to, the Korean version of the Mini Mental Status Examination (K-MMSE), a Modified Barthel Index (K-MBI), and the Berg Balance Scale (K-BBS). Caregiver satisfaction and burden before and after education programs were assessed using the Canadian Occupational Performance Measure (COPM), as well as family burden and caregiver burnout scales. RESULTS: No significant intergroup difference was observed between initial K-NIHSS, K-MMSE, K-BBS, K-MBI scores, and times from admission to transfer. Those with moderate or severe strokes under the experimental condition showed a more significant improvement than the control group as determined by the K-NIHSS and K-BBS, as well as tendential K-MMSE and K-MBI score increases. Satisfaction was significantly greater for family members and formal caregivers of patients with strokes of moderate severity in the experimental group. CONCLUSION: The caregiver's education program for stroke subjects had a positive outcome on patients' functional improvement and caregiver satisfaction. The authors believe that the additional rehabilitation therapy with the education program aids patients to achieve functional improvements for an optimal return to social life.
