This research was performed to investigate protective effect of Sophora Subprostrata fractions against focal ischemic brain damage after middle cerebral artery(MCA) occlusion. Rats were divided into six groups: MCA-occluded group(Control); each administered groups with Sophora Subprostrata total phase(Total), Sophora Subprostrata Aqueous phase (Aqueous), Sophora Subprostrata BuOH phase(BuOH), and Sophora Subprostrata Alkaloid phase(Alkaloid) after MCA-occlusion; sham-operated group(Sham). The right MCA was occluded by A poly-L-lysine coated 4-0 nylon suture thread through the internal carotid artery permanently. Sophora Subprostrata and fractions were administered orally(5mg/ml) for 7 days after MCA-occlusion. The behavior of ischemic rats were examined at 24 hours, 3, 5 and 7 days after MCA-occlusion from the views of 4 different aspects: posture & balance tests(4 subtests), reflex tests(6 subtests), muscle-tone tests(3 subtests), and foot-fault test. The results showed that 1) in muscle tone test, Sophora Subprostrata total phase only increased reduced muscle tone function from 3 to 7 days, 2) in reflex test, Sophora Subprostrata total and Aqueous phase increased fast recovery from 24 hours and 3 days, 3) in posture & balance test, Sophora Subprostrata total and Aqueous phase increased fast recovery from 24 hours, and Sophora Subprostrata BuOH and Alkaloid phase increased posture & balance function from 3 days, but 4) in motor function test, Sophora Subprostrata did not show effective recovery compared with control group. In conclusion, Sophora Subprostrata has protective effects against brain damage at the early stage of focal cerebral ischemia. Sophora Subprostrata total and Aqueous phase produced more pronounced protective effect against focal ischemic brain damage.

Following intravenous (IV) administration of diazepam as a preanesthetic agent, sudden balance impairment, such as falling, leaning, and rolling, was identified in 2 canine cases. The 2 dogs were anesthetized for brain magnetic resonance scan to diagnose about a history of head tilt. After end of the diagnostic procedures, during the anesthetic recovery period, balance impairment was also observed. However, the symptoms gradually ceased by IV administration of flumazenil. These 2 canine cases indicated that diazepam premedication was responsible for the acute balance impairment.

Purpose : This study was conducted to investigate the effect of muscle taping and joint taping on static and dynamic balance in normal adults with chronic ankle instability. Methods : The subjects of this study were 32 people who met the inclusion criteria. This cross-sectional study was conducted using the Kinesio tape, an elastic tape, was used. Subjects were randomized to exclude the effect of sequence, and no taping, joint taping, and muscle taping were applied as taping interventions. One-leg standing test and a Functional reach test were conducted to measure static balance, and Y-balance test was conducted to measure dynamic balance. One way repeated ANOVA was performed to investigate the difference in balance ability according to the taping intervention. If there was a significant difference, a post-hoc was performed using the Bonferroni method. Results : In the case of static balance, joint taping showed more significant results than did no taping and muscle taping (p<.05), and muscle taping showed more significant results than did no taping (p<.05). In the case of dynamic balance, muscle taping showed significantly larger results than did no taping and joint taping (p<.05) and joint taping showed significantly larger results than did no taping (p<.05). Conclusion : This study found that mechanical stimulation of muscles and joint compression by elastic taping increased ankle stability and improved static and dynamic balance. In particular, for static balance, joint taping was more effective than muscle taping, and for dynamic balance, muscle taping was more effective than joint taping. Applying the appropriate taping method to individual subjects has the advantage of maximizing the therapeutic effect for the recovery of balance ability. Similarly, the application of various tapings to subjects with ankle instability will have a positive effect on functional improvement.

본 연구는 다양한 좌석 높이에서 일어서기 훈련이 뇌졸중환자의 균형에 미치는 영향에 대해 알아보고자 연구를 실시하였다. 연구의 대상자는 뇌졸중환자 20명이며 무작위로 표준좌석 높이 그룹 10명과 낮아지는 좌석높이그룹 10명으로 분류하여 2019년 3월에서 6월까지 주 3회 6주간 훈련을 실시하였다. 정적균형과 동적균형을 측정하였으며 그룹 내 훈련 전·후의 변화를 검증을 위하여 대응표본 t-검정을 실시하고, 그룹 간 훈련 전·후 변화의 차이를 검증하기 위하여 독립표본 t-검정을 실시하였다. 연구 결과, 그룹 내 훈련 전·후의 변화는 정적균형 및 동적 균형 모두 유의한 변화를 보였으나(p<.05), 그룹 간 훈련 전·후 변화량의 차이는 눈 감은 상태의 선자세 정적균형만 유의한 차이를 보이지 않았다(p>.05). 본 연구의 훈련이 뇌졸중 환자의 균형에 유의한 효과가 있음을 확인하였으며 특히, 훈련 시 좌석의 높이를 점진적으로 낮추어 제공하는 것이 뇌졸중 환자의 균형회복을 위한 새로운 치료방법으로 임상에서 활용되어 재활의 다양한 방향성을 제시되었음으로 사료된다. 그리고 연구 결과의 일반화를 위해 추후 연구는 많은 대상자에게 훈련의 적용이 필요하며 좌석 높이의 무작위 조성과 같은 다양한 훈련방법에 관한 연구들이 필요할 것이다.

We investigated recovery in $Au/YBa_2Cu_3O_7$ (YBCO) thin film meander lines on sapphire substrates. The meander lines were fabricated by patterning YBCO films coated with gold layers. The lines were subjected to simulated AC fault current and then small current was applied for recovery measurements. The samples were immersed in liquid nitrogen during the experiment. After the fault, the resistance decreased linearly, first slowly and then fast to zero. The initial slow decrease was due to the decrease of the meander line temperature, whereas the fast decrease was originated from the transition from the normal state to the superconducting state. The recovery speed depended on the size of samples, and was faster in the smaller samples during the whole period of recovery. The experimental results were analyzed quantitatively with the concept of heat transfer within the sample and to the surrounding liquid nitrogen. A heat balance equation was solved for the initial phase of recovery, and an expression for the time dependence of resistance was obtained. The result agreed with data well.

An electric steam boiler equipped with a condensate recovery system, which stores the condensate generated after using steam in steam washers, steam cookers, steam irons, and steam cleaners in a condensate tank and supplies compressed air to the condensate tank so that the condensate is recovered to the boiler by the pressure of the compressed air, was studied. In the results of this study, the heat energy balance between the quantity of the heat generated by the non-metallic surface heating element and the quantity of the heat absorbed by the water was good in a range of ${\pm}5%$. In addition, the heat transfer rate increased in proportion to the electric power of the surface heating element heater, the waste heat energy was normally recovered by the recovery of the condensate of the steam boiler equipped with the high compression waste heat recovery system, and the recovery rate of the waste heat exhibited 23%.

The purpose of this study was to examine the relationship of the Stroke Rehabilitation Assessment of Movement (STREAM), the Berg Balance Scale (BBS), and the Modified Barthel Index (MBI) in the acute stroke care setting. Twenty patients with their first stroke were evaluated using STREAM, BBS, and MBI initially and at 4 weeks. The data was analyzed using the independent t-test, paired t-test, and the Pearson product moment correlation analysis. The scores on the STREAM were strongly associated with the scores on both the BBS and MBI (with Pearson correlation coefficients ranging from .88 to .95), and there was significant improvement between the initial scores and those obtained four weeks later for STREAM, BBS, and MBI (p=.001, p=.001, p<.001). The results suggest that STREAM may be able to reflect functional recovery and to assess voluntary movement in patients who have suffered an acute stroke.

Purpose: This study examined the effects of upper- and lower-limb coordinated exercise with proprioceptive neuromuscular facilitation (PNF) on stroke patients' recovery of their balancing and walking abilities. Methods: This study was conducted with 30 patients aged at least 60 years and diagnosed with stroke. The patients were randomly assigned to either a PNF upper- and lower-limb coordinated exercise group of 15 patients or an aero-step balance exercise group of 15 patients. To test the subjects' balancing and walking abilities, balancing ability tests and 10-m walking speed tests were conducted before and after the interventions. The patients performed their respective exercises for 30 minutes per session, three times per week for four weeks. The PNF exercise group performed six stages of exercise consisting of a combination of PNF patterns such as sprinting, skating, and striking. The six stages (right striking, right skating, right sprinting, left striking, left skating, and left sprinting) were performed continuously with a rest period of 1 min. after training for 4 min. The exercises for the aero-step balance group consisted of balancing in a two-leg standing position, weight shifting in a two-leg standing position, one-leg standing, squat exercises, marching in place, and squatting on an aero step. Results: The PNF exercise group showed significant improvements in their balancing ability evaluations compared to the aero-step balance group and also showed significant improvements in their 10-m walking speed tests. Conclusion: Based on the results of this study, PNF upper- and lower-limb coordinated exercise resulted in clinical improvements of stroke patients' balancing and walking abilities. Therefore, this type of exercise is recommended as a clinical intervention for the recovery of stroke patients' lower-limb function. Future studies should be conducted with longer intervention periods and more subjects to generalize the study results.

Introduction: Gullain-Barre syndrome (GBS) is a rapid, symmetric muscle weakness that often follows respiratory or gastrointestinal infections. Standard treatments include plasmapheresis and intravenous immunoglobulin, but outcomes can vary among patients. The integration of Korean medicine, notably unexplored in quantitative assessments of balance and walking, provides a novel approach to treatment. Case presentation: A 53-year-old male diagnosed with GBS presented to the hospital 8 days post-onset. He received treatments consisting of acupuncture, electroacupuncture, and rehabilitation over a period of approximately 4 weeks. Upon admission, the patient exhibited symptoms of both limb weakness and paresthesia, requiring the use of a wheelchair. Post-treatment, muscle strength and balance were significantly improved, leading to the restoration of independent ambulation, including running. Conclusions: This case illustrates the potential of integrated Korean and conventional medical treatments to accelerate recovery in GBS patients, overcoming typical prognosis timelines. The improvements in gait and balance were substantiated by quantitative assessments, suggesting a promising area for further research into the effects of combined therapeutic approaches to GBS recovery.
