OBJECTIVE: To examine the synergistic effects of both computer-assisted cognitive rehabilitation (CACR) and transcranial direct current stimulation (tDCS) on cognitive function in patients with stroke. METHODS: The current double-blind, sham-controlled study enrolled a total of 11 patients who were newly diagnosed with stroke. The patients of the tDCS group (n=6) completed sessions of the Korean computer-assisted cognitive rehabilitation program five times a week for 30 minutes a session during a mean period of 18.5 days concomitantly with the anodal tDCS over the bilateral prefrontal cortex combined with the CACR. The patients of the control group (n=5) also completed sessions of the sham stimulation during a mean period of 17.8 days. Anodal tDCS over bilateral prefrontal cortex (F3 and F4 in 10-20 EEG system) was delivered for 30 minutes at an intensity of 2 mA. Cathode electrodes were applied to the non-dominant arm. All the patients were evaluated using the Seoul Computerized Neuropsychological Test (SCNT) and the Korean Mini-Mental State Examination. RESULTS: Mann-Whitney U test revealed a significant difference between the two groups. The patients of the tDCS group achieved a significant improvement in the post/pre ratio of auditory continuous performance test and visual continuous performance test on the SCNT items. CONCLUSION: Our results indicate that the concomitant use of the tDCS with CACR to the prefrontal cortex may provide additional beneficial effects in improving the cognitive dysfunction for patients with stroke.

Dementia is one of major problem worldwide, and leading to great social and economic expense for medical and family care. Many of medical treatments have been introduced and performed to deal with this devastating disease but none could be publicized as clear evidence related with cure of dementia. Recently, it was reported that physical exercise could be useful approach to delay or prevent dementia. According to the recent Cochrane review of 16 previous literatures, exercise programs showed positive effect on the ability of performing daily activities and cognition in people with dementia. To help understanding of exercise therapy for dementia, in this review, the effect of exercise on recognition ability according to aging was investigated through the previous published papers and the proper exercise program was introduced for patients with dementia.

Transcranial direct current stimulation (tDCS) has considerable potential as a useful method in the field of neurorehabilitation. However, the safety of tDCS for the human is primarily based on theoretical evidence related to electricity, and the safety information of applying tDCS to the human is only available from researcher's reporting. Based on tDCS studies with human and animal subjects and simulation-based studies of the safety of current stimulation in the past 20 years, this review investigated the safety of tDCS application to the human body. No severe complications have been reported in either adults or children for tDCS at an intensity of 4 mA or less, within a period of 60 minutes per day, using commonly applied 25 or 35 cm 2 electrodes. According to animal studies, the amount of electricity used for tDCS is less than 5% of the amount that permanently changes brain tissue, thereby ensuring safety to a certain extent. In order to increase the efficacy of tDCS for neurorehabilitation and to minimize even trivial complications in the human screening of exclusion criteria should be conducted with detailed observations of complications.

OBJECTIVES: To investigate the lower extremity blood flow in hemiplegic patients with a quantitative Doppler ultrasound examination of the common femoral artery(CFA). METHODS: Cross-sectional area(CSA), peak systolic velocity(PSV) and inflow volume(IV) of CFA of normal and paralyzed limbs in 24 hemiplegic patients were measured with a Doppler ultrasound. Patients were divided into three groups according to the ambulation levels: 1) nonambulator, 2) assisted ambulator, and 3) independent ambulator. The results from Doppler images of paralyzed lower extremity were compared with the normal side in each three different groups. RESULTS: In the nonambulator group, the three parameters were not significantly different between normal and paralyzed lower extremity. In the assisted ambulator group, the CSA of the paralyzed lower extremity was significantly smaller than the normal side (p<0.05). In the independent ambulator group, the CSA and IV of the paralyzed lower extremity were significantly smaller than the normal side (p<0.05). CONCLUSION: The results of this study proved that the blood flow of the paralyzed lower extremity was diminished than the normal side in hemiplegic patients especially for the independent ambulator group.

Significant illnesses or a major trauma including spinal cord injury can induce the changes of thyroid hormone metabolism, leading to the findings of "Euthyroid Sick Syndrome(ESS)". The physicians should be aware of these changes in order to interpret thyroid function test correctly after the spinal cord injury. We report three cases of ESS after the spinal cord injury. On a routine evaluation, they showed a low serum T3 level, and the T3 level returned to the normal range on a follow up study without any specific treatment.

The experimental evidences suggest that the roles of basal ganglia are cognition and emotion through the corticostriatothalamocortical relationship. The patients with lesions in the caudate nucleus have high incidences of cognitive and behavioral abnormalities accompanied with the motor paralysis. In these patients, the accurate assessment of neuropsychologic dysfunctions and the prompt application of cognitive rehabilitation programs are important for the functional restoration. We evaluated the patients with stroke of basal ganglia for the clinical and neuropsychological characteristics in relation to the involved substructures of basal ganglia. Fourteen patients were evaluated for the clinical neurologic examinations, functional assessment by functional independence measure(FIM), speech assessment, and various neuropsychological tests for the assessment of attention and memory functions. The results were analysed a ccording to their lesion sites. Of the nine patients with stroke at the right basal ganglia, five patients had neglect of the contralateral hemispace and one had dysarthria. On the other hand, of the five patients with stroke at the left basal ganglia, none had hemispatial neglect and three had aphasia or dysarthria. Of the six patients with caudate lesions, three had aphasia or dysarthria, whereas of the eight patients without caudate lesion, one had dysarthria. The scores of Wechsler memory test were significantly lower in the patients with caudate lesions(P<0.05). Among the FIM subscales, the scores of communication and social cognition were significantly lower in the patients with caudate lesions(P<0.05). The Motor Score was significantly lower in the patients with putamen lesions(P<0.05). Among the FIM subscales, the scores of self care and locomotion were significantly lower in the patients with putamen lesions(P<0.05).

OBJECTIVE: To evaluate the effect of a contralateral shoe-lift and ipsilateral leather outsole on the energy consumption in hemiplegic gait. METHOD: Ten hemiplegic patients who could walk independently were enrolled. Using portable ergospirometer (K4b2, Cosmed, Italy), quantitative evaluation of oxygen consumption under varying shoes conditions was done: 1) regular shoes 2) a half-inch shoe-lift on the sound side 3) a half-inch shoe-lift on the sound side and leather outsole on the plegic side. The evaluation distance was 20 meter on comfortable walking speed. RESULTS: The oxygen consumption was significantly decreased after the application of shoe-lift compared with regular shoes (p<0.01), and the oxygen consumption was least with the application of shoe-lift and leather outsole (p<0.05). This effect was prominent in subject with poor muscle power in hemiplegic lower extremity. The walking speed was also increased with shoe-lift and leather outsole (p<0.05). CONCLUSION: The results of this study demonstrate that proper shoes modification can reduce the energy consumption in hemiplegic gait and can lead to more efficient functional ambulation.

OBJECTIVE: The objectives of this study were to evaluate the reliability of the Korean version of Spinal Cord Independence Measure (SCIM) and to compare the sensitivity of the SCIM to functional changes of spinal cord injury (SCI) patients with that of the Functional Independence Measure (FIM). METHOD: Seventeen subjects with SCI were studied. The SCIM was translated and modified to convert as SCIM Korean-version. All patients were evaluated with the SCIM and the FIM by two raters every other week. To determine inter-rater reliability, the relationship between the SCIM scores obtained by two raters was evaluated by Kappa coefficient and linear regression. To determine relative sensitivity of the test to functional changes, changes in the scores on the SCIM and FIM were compared by McNemar test. RESULTS: The Kappa coefficient of the various individual tasks in SCIM ranged between 0.63 and 1.00. High correlations were also found between the total SCIM scores for the paired raters (r=0.99, p<0.01). The SCIM detected all the functional changes detected by FIM total scoring, but in 3 (14%) of 22 sequential test batteries, the FIM missed changes detected by SCIM total scoring. CONCLUSION: These results demonstrated that the SCIM is reliable and more sensitive than the FIM in reflecting the functional changes of SCI patients.

Trauma is one of the causes of lymphedema. However, we usually do not consider it as a cause of the lymphedema, thus, we often fail to take care of the patients properly. We report a patient with post traumatic lymphedema and the result of complex decongestive therapy, and reviewed the clinical, lymphoscintigraphic findings and treatment.

objective: This study was conducted to assess effects of intramuscular stimulation (IMS) in comparison with that of dry needling and intramuscular electrical stimulation (IMES) in the patients with myofascial pain syndrome (MPS) of upper trapezius. METHOD: Thirty patients with MPS were assigned randomly to three groups, such as dry needling group (n=10), IMES group (n=10), and IMS group (n=10). In dry needling group, dry needling was applied to the trigger point of upper trapezius muscle. In IMES group, IMES was applied to the trigger point of upper trapezius muscle. In IMS group, IMS was applied to the trigger point of upper trapezius and parcervical muscles. Treatment were done three times a week for 2 weeks. Effects were assessed on 3rd day, 7th day and 14th day after treatment by visual analogue scale (VAS), McGill pain questionnaire (MPQ), and passive range of motion (PROM) of cervical spine. RESULTS: Significant changes of VAS and PROM were noticed in IMS group, compared with other groups. No significant difference of MPQ was noticed in IMS group, compared with other groups. CONCLUSION: IMS may be more effective treatment modality than dry needling and IMES in patients with MPS of upper trapezius muscle.
