Purpose: To design novel balance tests to assess FAI and evaluate whether these tests are affected by BMI or gender, with the goal of developing reliable FAI assessment tests that are not influenced by these factors. Materials and Methods: Participants included 20 young, healthy volunteers, 12 males and 8 females, with a mean age of $24{\pm}4$ years and a mean BMI of $23{\pm}2.28$. None of the subjects had known ankle instability. The following tests were assessed in each participant: single leg balance (SLB), percentage of leg press (PLP), single leg cycling (SLC), one leg squat (OLS), multiple direction reach-front/back/side (MDR-F/B/S), single leg hop (SLH), two leg jump (TLJ) and side step (SS). Data were analyzed using the SPSS 12.0 software program with ANOVA and t-test used. Results: When grouped by BMI, we found that despite differences in BMI, the performances of all subjects were equivalent except for the one-leg-squat test, for which the mean ratios for underweight ($1.69{\pm}0$), normal weight ($1.05{\pm}0.19$), and overweight ($0.93{\pm}0.30$) individuals were significantly different (p=0.02); ratios for SLB (p=0.273), SLC (p=0.903), PLP (p=0.664), MDR-F/B/S (p=0.498, 0.908, and 0.503, respectively), SLH (p=0.332) were not significantly different. When calculated according to gender, we found that the OLS (p=0.013) and MDRS (p=0.034) were significantly different, while parameters for all the remaining tests were not affected. Conclusion: We found that the SLB, PLP, SLC, MDR-F/B, and SLH ratios were unaffected by BMI or sex and, therefore, are reliable parameters for assessing ankle instability.

This study examined the effects of 8-weeks hip muscle training on the hip joint abductor muscle isokinetic strength and foot pressure distribution in elite players with chronic ankle instability (N=19). A total of 19 subjects had chronic ankle instability from at least 2 ankle sprains, and were given 8-weeks hip muscle training exercise. The hip muscle strength of the elite players with chronic ankle instability increased significantly, but the foot pressure distribution and ratio of the foot pressure distribution of the elite players with chronic ankle instability did not reach statistical significance and the ratio of the foot pressure distribution showed a similar trend. These results suggest that the strength and foot pressure distribution of the affected-side might increase to that of the unaffected-side. The 8-weeks hip muscle training helped improve the chronic ankle instability of the elite players. Therefore, the hip muscle strength and foot pressure distribution are the primary factors of a rehabilitation program on ankle sprains.

Purpose: To evaluate the usefulness of quantitative analysis of the facial nerve using contrast-enhanced three-dimensional (CE 3D) fluid-attenuated inversion recovery-volume isotopic turbo spin echo acquisition (FLAIR-VISTA) for the diagnosis of Bell's palsy in pediatric patients. Materials and Methods: Twelve patients (24 nerves) with unilateral acute facial nerve palsy underwent MRI from March 2014 through March 2015. The unaffected sides were included as a control group. First, for quantitative analysis, the signal intensity (SI) and relative SI (RSI) for canalicular, labyrinthine, geniculate ganglion, tympanic, and mastoid segments of the facial nerve on CE 3D FLAIR images were measured using regions of interest (ROI). Second, CE 3D FLAIR and CE T1-SE images were analyzed to compare their diagnostic performance by visual assessment (VA). The sensitivity, specificity, and accuracy of RSI measurement and VA were compared. Results: The absolute SI of canalicular and mastoid segments and the sum of the five mean SI (total SI) were higher in the palsy group than in the control group, but with no significant differences. The RSI of the canalicular segment and the total SI were significantly correlated with the symptomatic side (P = 0.028 and 0.015). In 11/12 (91.6%) patients, the RSI of total SI resulted in accurate detection of the affected side. The sensitivity, specificity, and accuracy for detecting Bell's palsy were higher with RSI measurement than with VA of CE 3D FLAIR images, while those with VA of CE T1-SE images were higher than those with VA of CE 3D FLAIR images. Conclusion: Quantitative analysis of the facial nerve using CE 3D FLAIR imaging can be useful for increasing the diagnostic performance in children with Bell's palsy when difficult to diagnose using VA alone. With regard to VA, the diagnostic performance of CE T1-SE imaging is superior to that of CE 3D FLAIR imaging in children. Further studies including larger populations are necessary.

The purpose of this study was to develop a multidisciplinary team approach program for stroke survivors, and to identify its effects on their rehabilitation. The team was composed of 7 members: a rehabilitation nurse, a physician, a physical therapist, an occupational therapist, a therapeutic recreational therapist, a nutritionist, and a researcher. A quasi-experimental study was performed with 36 subjects: 18 in the experimental group and 18 in the control group, using a noneqivalent control group pretest-posttest design. The experimental group participated 4 times in rehabilitation programsfocused on information and emotional support provided by the rehabilation team-and received telephone counseling from the researcher. The control group did not receive any treatment. The selection criteria for the subjects in this study were: (a) patients who were diagnosed as having had an ischemic stroke within the last year, (b) patients free of any communication disorder, (c) and those having a primary caregiver who could assist in filling out the form assessing the level of ADL. The data were collected from patients who had been discharged from a tertiary hospital, between October 1st, 1999 and September 30th, 2000. The data were analysed by $X^2$ test, Fisher's exact test, ANCOVA, Wilcoxon's rank sum test, and Wilcoxon's signed rank test using an SAS program. The results were as follows: 1. In terms of physical variables (blood pressure, grasp power, and ADL) 1) There was a significant difference in blood pressure between the two groups (systolic pressure P= .012, diastolic pressure P= .050). 2) There was also a significant difference in grasp power between the two groups (affected side : P= .012, unaffected side : P= .010). 3) There was no significant change in the level of ADL between the two groups. 2. In terms of psychosocial variables (depression, self-efficacy, self-esteem, and social activities) 1) There were no significant differences between the two groups. However, all four psychosocial variables showed a tendency to improve in the experimental group, while only two variables (depression and self-efficacy) showed a simalar tendency in the control group. 2) The level of social activities in the control group decreased significantly after a month (P= .050). 3. The level of life satisfaction improved in both groups, but no significant difference was found. Stroke has high recurrence rate and requires considerable follow-up care. The program used in this study was developed and designed for stimulting the rehabilitation process of stroke survivors. Through the program period of one month (meetings were held weekly), a positive effect was detected in physical variables, although the psychosocial variables did not improve significantly. In retrospect, a one month period may not be an adequate length of time to improve the psychosocial variables, as the stroke survivors were complicated cases, and most of them were elderly. Further research is therefore recommended by increasing the length of program, so that its effect can be more noticeable.

Objectives : Electrical acupoint stimulation(EAS) has been used to treat motor dysfunction of stroke patients with reportedly effective results. The purpose of this study is to evaluate the efficacy of the EAS with different frequencies in treating motor dysfunction of ischemic stroke patients. Methods : The subject of this study were forty-two ischemic stroke patients with motor dysfunction in Kyunghee oriental medicine hospital who were hospitalized for one week to one month from onset. They were treated with 2Hz or 120Hz EAS for two weeks, and motor evoked potentials(MEP) were measured before and after EAS treatment. To compare the effect of 2Hz EAS with 120Hz, the number of patients who showed MEP responses after two weeks among those who had no previous response was checked. Also measured were latency, central motor conduction time(CMCT), amplitude of MEP before and after EAS treatment. Results : After two weeks of treatment, 4 out of 15 patients(27%) in the 2Hz EAS group and lout of 19 patients(5%) in the 120Hz group showed potential responses. Yet there was no significant difference between the two groups. When MEP data of the affected side between the 2Hz group and the 120Hz group was compared, the former showed more significant improvement than the latter in latency, CMCT and amplitude(P=0.040, 0.019,0.021). When the proportion of the affected side and unaffected side in MEP data was examined, the 2Hz group showed improvement on only latency and CMCT with significant differences(P=0.040, 0.014). Conclusions : These results show that EAS with low frequency is more helpful for motor recovery after ischemic stroke than that with high frequency. This suggests that low frequency EAS activates the central motor conduction system better than high frequency EAS.

The purpose of this study is to examine effects of constraint-induced movement therapy(CIMT) and/or cognitive-perceptual training(CPT) on the change of hand function in cerebrovascular accident(CVA) patients and to evaluate the change in the amount and quality of use of the affected upper extremity in performing daily living tasks. The subjects of study were 10 patients who had been under rehabilitation for more than three months after CVA onset. They were all determined as mild cognition impairment according to NCSE or MVPT test. For CIMT group, to restrict the movement of the unaffected hand the subjects had been worn modified resting arm-splint in daytime for 4 weeks. For CIMT+CPT group, the subjects were performed CPT with CIMT and control group had been under conventional occupational therapy for the same period. CIMT+CPT group showed significant improvement in simulated feeding, lifting large light objects, and lifting large heavy objects of Jebsen-Taylor Hand Function Test. CIMT group also showed significant improvement compared with control group. The mean changes of the amount of use(AOU) of the affected arm had a statistically significant difference among groups (p<.05). While CIMT+CPT group had the biggest change in the quality of movement(QOM) of upper extremity of the affected side, CTL group showed the smallest change. Both CIMT and CIMT+CPT groups had statistically significant difference in the change in the quality of movement in upper extremity of affected side with CTL group(p<.05), but there was not significant difference between CIMT group and CIMT+CPT group. CIMT performed to the patients of stroke, with mild impairment in cognitive perceptual abilities showed the improvement in hand movement and AOU and QOM of upper extremity in the affected side and the combination of CIMT with CPT showed synergic effects.

The majority of chronic gingival ulcerative lesions are known to be due to autoimmune disease such as oral lichen planus, benign mucous membrane pemphigoid or pemphigus vulgaris. Topical or systemic corticosteroids are mainly used and adjuvant drugs like immunosuppressant, anti-inflammatory drugs, antimalarials or antimetabolites can also be prescribed. Because systemic corticosteroids causes various side effects, such as gastrointestinal disturbance, osteoporosis, diabetes or adrenal suppression. So, topical steroid therapy is main treatment for chronic gingival ulcerative lesion confined to small area. However, there's also limitation of topical corticosteroids. The effect of the corticosteroids decreases due to salivary flow and the movement of the tongue, lips, or buccal mucosa. When the lesions are widely distributed or positioned deeply in oral cavity, it is hard to apply the medication on patients' own. Moreover, it can be applied to unaffected mucosa. Although occlusive steroid therapy using stent was reported to minimize taking steroid and overcome the faults of applying topical steroids, it has been used less frequently in the clinical field. Therefore, this report is going to find out the usefulness and the way to utilize clinically through the case which acted satisfactorily by performing topical steroid therapy using stent on chronic ulcerative gingival lesions.

The purpose of this study was to determine the effect of DHEA on Type I(soleus) and II muscles(plantaris, gastrocnemius) in a focal brain ischemia model rat. Thirty-seven male Sprague-Dawley rats with $200{\sim}250g$ body weights were randomly divided into four groups : CINS(cerebral ischemia + normal saline), CIDH(cerebral ischemia + DHEA), SHNS(sham + normal saline), SHDH (sham + DHEA). Both the CINS and CIDH groups were undergone a transient right middle cerebral artery occlusion operation. In the SHNS and SHDH groups, a sham operation was done. DHEA was administered daily at a dose of 0.34mmol/kg, and normal saline was administered daily at the same dose by intraperitoneal injection for 7days after operation. Cerebral infarction in the CINS and CIDH groups was identified by staining with 2% triphenyltetrazolium chloride solution for 60 minutes. The data were analyzed by Kruskal-Wallis test and Mann-Whitney U test using the SPSSWIN 9.0 program. The results were summarized as follows: 1) The muscle weights of soleus(Type I), plantaris and gastrocnemius(Type II) in CINS group were significantly less than those of the SHNS group(p<.01). The muscle fiber cross-sectional area of the CINS group was significantly less than that of the SHNS group in Type I muscle fiber of the soleus and Type II muscle fiber of the plantaris and gastrocnemius(p<.05). The myofibrillar protein content of the CINS group was significantly less than that of the SHNS group in the left gastrocnemius and right soleus(p<.05). 2) The muscle weights of the soleus, plantaris and gastrocnemius except the unaffected side of the plantaris in the CIDH significantly increased compared to those of the CINS group(p<.05). The muscle fiber cross-sectional area of the CIDH group significantly increased compared to that of the CINS group in Type II muscle fiber of the plantaris and gastrocnemius(p<.05). The myofibrillar protein content of the CIDH group significantly increased compared to that of the CINS group in the left soleus(p<.05). 3) On the post-op 8 day, the body weight of the CINS group was significantly less than that of the CIDH, SHNS and SHDH groups(p<.01). Total diet intake of the CINS and CIDH groups was significantly less than that of the SHNS and SHDH groups(p<.01). Based on these results, it was identified that muscle atrophy could be induced during the 7 days after cerebral infarction, and DHEA administration during the early stage of cerebral infarction might attenuate muscle atrophy.

The effects of tuna oil supplementation (0, 1, 2 and 3%) to pig diets on growth and carcass yield as well as meat quality were determined in 40 crossbred pigs. Animals were fattened from 30 to 90 kg of live-weight. Twenty-four hours after slaughter, following various early- and late-post mortem measurements, loin, backfat and belly were prepared from the carcasses. Bacon was produced from the belly part by curing and smoking. Neither performance (feed intake, daily gains, feed conversion efficiency) nor carcass quality (slaughter weight, dressing percentage, lean percentage, nutrient composition of the loin) were significantly affected by tuna oil supplementation. Tuna oil also had no clear effects on early- and late-post mortem meat quality traits, water-holding capacity and tenderness of the M. longissiumus dorsi (LD). Colour traits of LD and backfat, and backfat firmness were not significantly affected by tuna oil, either. However, there was a certain trend to elevated fat contents of LD (and bacon), but not of backfat, with increasing levels of tuna oil in feed. Pigs receiving elevated proportions of tuna oil expressed lower VLDL cholesterol and triglyceride concentrations in blood plasma, whereas the cholesterol content of LD, backfat and bacon did not reflect this trend. Effects of tuna oil on fatty acids in LD, backfat and bacon were often small in extent, except those concerning the long-chain polyunsaturated fatty acids. With 3% tuna oil in the diet, the contents of the particularly desired omega-3 fatty acids, C20:5 and C22:6, were 0.1 and 0.2 g/kg in LD. The corresponding values for backfat and bacon were 2.6 and 12.6 g/kg, and 1.3 and 9.2 g/kg, respectively. Tuna oil supplementation was associated with significant adverse effects on flavour and overall acceptance of bacon (not significant in LD although numerically the same trend was noted), but these effects on sensory ratings were limited in extent. Also shelf life of the products, determined as TBA value after different storage periods at $4^{\circ}C$ in LD, backfat and bacon, was significantly reduced. Overall, the present study suggests that omega-3 fatty acids may be enriched in pork by feeding tuna oil with few undesired side-effects, particularly those on sensory perception and shelf life, suggesting immediate consumption of the products is advisable. Most economically important traits (performance, slaughter and physical meat quality) remained unaffected.
