PURPOSE: The purpose of this study was to investigate the effects of differences in exercise time arrangement on the functional recovery of the lower limbs and balance of stroke patients. METHODS: The subjects of this study were 100 patients who were hospitalized in two hospitals located in Gyeonggi-do. Before the experiment, 60 of these patients who met the inclusion criteria and did not meet the exclusion criteria were randomly divided into an experimental group (n = 30), whose exercise time was concentrated, and a control group (n = 30), whose exercise time was diffuse. The two groups underwent six weeks of physical and occupational therapy four times a day for five days a week. One session of therapy took 30 minutes, including three sets of physical therapy and one set of occupational therapy. The rest time between the sessions was different for each group. The experimental group had five minutes of rest between each therapy session, and the control group had two hours of rest time between each session. The Fugl-Meyer assessment (FMA), an assessment of each patient's limit of stability (LOS), and a timed up and go test (TUG) were used as test tools. RESULTS: Both groups showed statistically significant increases in their FMA results, LOS measurements, and TUG results. The FMA results of the experimental group were significantly higher than those of the control group. CONCLUSION: Thus, concentrated exercise time was more effective than diffuse exercise time for the recovery of motor function.

The aim of this study is to investigate the effects of onion vinegar on the cerebral blood flow by measuring the changes of regional cerebral blood flow (rCBF) and mean arterial blood pressure (MABP) and by observing the recovery of focal ischemic brain injury in rats. Rats are divided into thee groups depending on the medication; control group (no medication), 8.8-OV group (vinegar using 8.8 brix onion medication), 14.6-OV group (vinegar using 14.6 brix onion medication). The medication of onion vinegar significantly increased rCBF but decreased MABP. This result suggests that onion vinegar significantly increased rCBF by dilating arterial diameter. In addition, focal ischemic brain injury is induced in rats by middle cerebral arterial occlusion. The recovery from focal ischemic brain injury is more significantly improved in the groups using onion vinegar compared to the control group. The amount of recovery is measured by the GAP-43 and the medication of onion vinegar significantly increased GAP-43. This result suggests that onion vinegar is effective on the nerve regeneration. After the medication, the change of body weight, outcomes of renal and liver function test, and outcomes of CBC are analysed for safety examination. There are no statistical differences among control group and all experimental groups in the body weight, renal and liver function test, and CBC. In conclusion, these results suggest that onion vinegar can increase rCBF in normal state, and improve the stability of rCBF in ischemic state.

PURPOSE: The purpose of this paper is to provide a review of physiotherapy intervention for patients with COVID-19 during their hospital admission and post-discharge. METHODS: The recommendations and guidelines of physiotherapy management, medical management, and general information of the WHO, Australian Physiotherapist, European Respiratory Society, British Thoracic Society, and American Thoracic Society were reviewed. RESULTS: This paper contains general information on COVID-19, including medical management, and the importance of physiotherapy approaches including an assessment of the patients' function, such as the 6-minute walking test, five sit to stand or sit to stand for one minute to measure their function as their recovery journey. The patients' quality of life, anxiety, and depression should be considered. Physiotherapy management should be based on an assessment of the patient's presenting impairments, including inclusion and exclusion of physiotherapy intervention. The paper also approaches step by step with the disease progress, from an intensive care unit, the general ward in the acute phase, through to the rehabilitation ward if needed, and post-discharge as an outpatient.. CONCLUSION: The paper has a limitation due to the unknown factor of the natural history of COVID-19. Depending on the patients' recovery journey and the rehabilitation needed, any physiotherapy interventions should focus on what the patients' need on their journey to recovery, e.g., pulmonary, cardiac, neurological, and general rehabilitation. In addition, applying personal protection equipment for treating physiotherapists is a mandatory requirement because this protects from the transmission of COVID-19.

Objectives : To research trends of studies on treatments of knee osteoarthritis in Korean medicine. Methods : Domestic theses, published from 2000 to 2010, mentioning the treatments of knee osteoarthritis in Korean medicine were reviewed and analyzed. This study researched 79 theses and classified again according to the fields of the treatment. Results : The results were obtained as below ; 1. Studies on pharmacoacupuncture account for 41% of the total (32cases/79cases). The target of treatments had changed from pain alleviation and anti-inflammation to cartilage-protection since 2006. 2. Herbal Drug, Bee Venom, Cervi Cornu Parvum pharmacoacupuncture, Taping Therapy and Tai-Chi Exercise program were more effective than others. Moreover research on exercise program such as Tai-Chi has been increasing. 3. Some Herbal Drug (Glycyrrhizae Radix, Angelicae Gigantis Radix, Achyrantis Radix, Paeoniae Radix, Eucommiae Cortex and so on) were mainly used to investigate the effect on cartilage protection, pain relief and anti-inflammation in laboratory test. 4. Acupuncture including individualized, local acupoints and constitution acupuncture were effective than others in pain alleviation and symptom relief. 5. Pharmacoacupuncture Bee Venom were effective in recovery of joint function and pain relief while Buthus martensii Karsch, Homnis Placenta and Cervi Cornu Parvum were effective in cartilage protection and recovery. 6. Moxibustion was efficient to reduce joint pain and partly increase ROM (range of motion) of knee joint, but was not efficient to recover the function of knee joint. Conclusions : These results indicate that research trends on knee osteoarthritis were changed from symptomatic treatment (pain alleviation and anti-inflammation) to conservative treatment (cartilage protection and recovery).

위험유해물질(HNS, Hazardous and Noxious Substances)은 해상운송 과정에서 다양한 사고에 노출되어 있어 많은 양이 바다에 유출될 우려가 있다. HNS 유출에 따른 해양환경의 손상은 유류 유출에 의한 손상보다도 훨씬 큰 것으로 알려져 있다. 특히 해저로 침강하여 침적되는 HNS는 해저생태계에 돌이키기 어려운 피해를 주게 되므로, 반드시 회수되어야 한다. 해저로부터 HNS를 회수하기 위해서는 해저침적 HNS에 대한 정확한 탐지, 안정화 처리 및 회수를 위한 절차와 장비가 필요하다. 그 중에서도 기계적 회수장치를 개발하기 위해서는 성능지표를 이용하여 성능요건을 선정하고, 이를 토대로 기계적 회수장치에 대한 개념설계가 이루어져야 한다. 따라서 본 연구에서는 해저침적 HNS의 회수 절차에서 요구되는 기계적 회수장치에 대한 개념설계안을 제시하였다. 개념설계안으로 해저침적 HNS를 회수하기 위한 기본 시나리오를 제시하고, 자체적 밀폐 성능을 가지는 흡인 기초를 활용하는 방안을 채택하였다. 기계적 회수장치는 흡인 기초, 오염 방지, 펌프 시스템, 제어 시스템, 모니터링 장비, 위치정보 장비, 이송 장비, 탱크로 구성된다. 이러한 개념설계안은 기계적 회수장치의 부품 및 형상을 결정하는 기본설계에 반영되어 활용될 것으로 기대된다.

PURPOSE: To prevent secondary complications from decreased pulmonary functions and promote neurological recovery, identification of respiratory capacity change patterns depending on different postures of stroke patients and investigation of their properties are needed for active rehabilitation. Therefore, this study was conducted to investigate the changes in vital capacity in response to different positions and to implement the results as clinical data. METHODS: A respiratory function test was administered to 52 patients with stroke in the sitting, supine, paretic side lying, and non-paretic side lying positions. Pulmonary function indexes used for comparison were forced vital capacity (FVC), forced expiratory volume at 1 second (FEV1), forced expiratory flow 25-75% (FEF 25-75%), and maximum voluntary ventilation (MVV). One-way repeated ANOVA was used for analysis, and post hoc analysis was conducted using least significant difference (LSD). RESULTS: All pulmonary function indexes were measured in the order of sitting, paretic side lying, supine, and non-paretic side lying positions. Excluding the FEF25-75% and MVV of the supine compared with the paretic side lying position, all other pulmonary function indexes differed significantly (p<.05). CONCLUSION: There are differences in pulmonary function indexes depending on different postures of stroke patients, and the study showed that the non-paretic side lying position yielded the greatest effect on lung ventilation mechanisms. Based on these results, appropriate postures need to be considered during physical therapy interventions for stroke patients.

Humans may lose considerable amounts of water and electrolytes from sweat during exercise in a hot climate. Optimal ingestion of fluid-replacement beverages may overcome an obstacle factor of exercise performance in the heat. This study was performed the comparison of heart rate and blood lactate between ingestion of Prunus mume solution and water solution during graded maximal exercise using bicycle ergometer in the heat(ambient temperature of 31-32$^{\circ}C$ and relative humidity of 50-55%). Ten healthy no-heat-acclimatized males participated in the study. Exercise duration until all-out of graded testing in the condition of Prunus mume solution ingestion(786.15$\pm$47.66s) was significantly higher(P＜0.05) than the condition of water ingestion. Heart rate at 4 min during graded testing and recovery phase in the condition of Prunus mume solution ingestion was significantly lower(P＜0.05) than the condition of water ingestion. Blood lactate concentration at 30min of recovery phase after graded maximal exercise in the condition of Prunus mume solution ingestion was significantly lower(P＜0.05) than the condition of water ingestion. Recovery rate of blood lactate concentration at 15 min and 30 min of recovery phase after grated maximal exercise in the condition of Prunus mume solution ingestion was significantly lower(P＜0.05) than the condition of water ingestion. Present results suggested that ingestion of Prunus mume solution showed the positive effects on the cardiorespiratory function and acid-base regulation as compared with ingestion of water during graded maximal exercise and recovery phase in hot environment.

Objective : Minocycline, a second-generation tetracycline-class antibiotic, has been well established to exert a neuroprotective effect in animal models and neurodegenerative disease through the inhibition of microglia. Here, we investigated the effects of minocycline on motor recovery and neuropathic pain in a rat model of spinal cord injury. Methods : To simulate spinal cord injury, the rats' spinal cords were hemisected at the 10th thoracic level (T10). Minocycline was injected intraperitoneally, and was administered 30 minutes prior surgery and every second postoperative day until sacrifice 28 days after surgery. Motor recovery was assessed via the Basso-Beattie-Bresnahan test Mechanical hyperalgesia was measured throughout the 28-day post -operative course via the von Frey test Microglial and astrocyte activation was assessed by immunohistochemical staining for ionized calcium binding adaptor molecule 1 (lba1) and glial fibrillary acidic protein (GFAP) at two sites: at the level of hemisection and at the 5th lumbar level (L5). Results : In rats, spinal cord hemisection reduced locomotor function and induced a mechanical hyperalgesia of the ipsilateral hind limb. The expression of lba1 and GFAP was also increased in the dorsal and ventral horns of the spinal cord at the site of hemisection and at the L5 level. Intraperitoneal injection of minocycline facilitated overall motor recovery and attenuated mechanical hyperalgesia. The expression of lba1 and GFAP in the spinal cord was also reduced in rats treated with minocycline. Conclusion : By inhibiting microglia and astrocyte activation, minocycline may facilitate motor recovery and attenuate mechanical hyperalgesia in individuals with spinal cord injuries.

This study divided a group of healthy adults aged 20 or older who had a health examination at J General Hospital in Gyeonggi Province into three groups according to the degrees of metabolic syndrome risk factors. They include the normal group (n=58), the pre-metabolic syndrome group (n=112) and the metabolic syndrome group (n=32). They were compared in exercise capacity and cardiac structure and function and impacts of exercise capacity on the cardiac diastolic function. All the groups took echocardiography to have their cardiac structures and functions examined and an exercise stress test to have their exercise capacity measured. The research findings were as follows: There were differences in exercise capacity, cardiac structure, and diastolic heart function among three groups. Between exercise capacity and diastolic heart function was found to be related. It turned out exercise capacity affected the cardiac diastolic functions. In conclusion, there were significant differences in exercise capacity between the normal group and the metabolic syndrome group and in the cardiac structure and function among the normal, metabolic syndrome, and pre-metabolic syndrome group. In addition, METs (metabolic equivalents) and heart rate recovery of exercise capacity turned out to affect cardiac diastolic functions.
