  • The purpose of this study was to explore the effects of GEAP on pain, joint function, activities of daily living(ADL) and fatigue in chronic arthritis patients. The GEAP was held twice a week for 6 weeks for chronic arthritis patients at one university hospital in Seoul, Korea. Thirty four subjects completed the program, who were recruited at four times from September, 1999 to September, 2000. The effect of GEAP were evaluated as follows: Pain severity and number of painful joints ADL, fatigue were measured before and after the GEAP. In order to examine the joint flexibility and strengthening, the followings were measured: the extent of the upward arm reach in both sides(flexibility of shoulder), the ability to touch fingertips of the both hands in back pat and rub(flexibility of arm), the degree of range of motion (ROM) of both ankles in their dorsiflexion(flexibility of ankle) and plantarflexion with standing with toe(strengthening of ankle), and the degree of knee extension, and the grip strength. Paired t-test and Wilcoxon signed rank test were used for data analysis and the significance of the differences in the variables was examined to compare the data obtained before and after the GEAP. After the GEAP, followings were found: 1. Pain severity and number of painful joints was significantly decreased. 2. The flexibility of both shoulders and arms, knee, both ankle were significantly improved. 3. The strengthening of both arms was significantly improved, but the strengthening of ankle was not changed. 4. ADL was significantly increased. 5. Fatigue was significantly decreased. In conclusion, GEAP used in this study was clearly proved to be an effective exercise program to reduce pain and fatigue, to enhance joint function and ADL in people with chronic arthritis. It is suggested that the GEAP should be recommended as one of the useful and appropriate nursing interventions for chronic arthritis patients.

  • The research is performed in order to know the relationship between the metabolic syndrome and the physical fitness targeted for menopausal women (over 45 years). All subjects were divided into 4 groups; group without risk factors of metabolic syndrome (MS-0: n=74), group having one risk factor of metabolic syndrome (MS-1: n=68), group having two risk factors of metabolic syndrome (MS-2: n=44), and group having more than three risk factors of metabolic syndrome (MS ${\geq}$ 3: n=30). All groups' height, weight, body mass index and percent of body fat were measured. High density lipoprotein cholesterol (HDL), triglyceride, glucose and blood pressure (BP) levels were measured. Their cardiorespiratory ($VO_2max$) endurance, muscular strength, muscle endurance, and flexibility were measured. HDL, triglyceride, glucose and BP levels in MS-1, MS-2, and MS ${\geq}$ 3 group were significantly greater than those of MS-0 group. The endurance ($VO_2max$) in MS ${\geq}$ 3 group was higher than that of MS-0 group. Multiple regression with the risk factors of metabolic syndrome and the physical fitness showed a statistical significance in only $VO_2max$. We found that the risk factors of the metabolic syndrome adversely affect postmenopausal women's $VO_2max$ and that a decreased $VO_2max$ may have prognostic value for the prediction of metabolic syndrome.

  • The purpose of this study is to review the effect of previous research data with virtual reality-based Physical Activity Therapy Programs(PATPs) in adult on the physical fitness factors. Research articles were retrieved from 2008 to 2021 with the Research Information Sharing Service(RISS) and Pubmed database. The main search terms were 'care', 'therapy', 'healing', 'exercise' or 'physical activity', and 'virtual reality'. The criteria for selecting articles of this study were the originality, duplication, Randomized controlled trial(RCT) experiment and subject. Finally, 18 papers were selected among 318 articles, which were excluded if any of the criteria was not satisfied. Most of papers(15) were conducted in the last 5 years, because of the high interest due to the development of virtual reality implementation technology and COVID-19 pandemic. The participants were mainly patients(8), and the types of diseases were stroke(2). The physical fitness factors were mostly balance ability(7), muscle strength(7), and range of motion(6). All the physical fitness factors were significantly improved after PATPs. However, 11 studies were conducted for less than 4 weeks, including 6 studies were performed a bout of acute exercise. Also, 14 studies did not clearly present the intensity of PATPs. In addition, there were 9 studies, that simply applied games without specialized programs. In conclusion, it seems that virtual reality-based PATPs have a positive effect on physical fitness factors. However, VR-based PATPs should be specialized and developed in order to verify their effectiveness for the further research.

  • Sports activities, including playing tennis, are popular with many people. As this industry has become more professionalized, investors and those involved in sports are sure to pay attention to any tool that improves athletes' performance Tennis requires perfect coordination between hands, eyes, and the whole body. Consequently, to perform long-term sports, athletes must have enough muscle strength, flexibility, and endurance. Tennis rackets with new frames were manufactured because tennis players' performance depends on their rackets. These rackets are distinguished by their lighter weight. Composite rackets are available in many types, most of which are made from the latest composite materials. During physical exercise with a tennis racket, nanocomposite materials have a significant effect on reducing injuries. Materials as strong as graphite and thermoplastic can be used to produce these composites that include both fiber and filament. Polyamide is a thermoplastic typically used in composites as a matrix. In today's manufacturing process, materials are made more flexible, structurally more vital, and lighter. This paper discusses the production, testing, and structural analysis of a new polyamide/Multi-walled carbon nanotube nanocomposite. This polyamide can be a suitable substitute for other composite materials in the tennis racket frame. By compression polymerization, polyamide was synthesized. The functionalization of Multi-walled carbon nanotube (MWCNT) was achieved using sulfuric acid and nitric acid, followed by ultrasonic preparation of nanocomposite materials with weight percentages of 5, 10, and 15. Fourier transform infrared (FTIR) and Nuclear magnetic resonance (NMR) confirmed a synthesized nanocomposite structure. Nanocomposites were tested for thermal resistance using the simultaneous thermal analysis (DTA-TG) method. scanning electron microscopy (SEM) analysis was used to determine pores' size, structure, and surface area. An X-ray diffraction analysis (XRD) analysis was used to determine their amorphous nature.

  • Purpose: The aim of this study was to predict the subgroups vulnerable to poorer health-related quality of life (HRQoL) according to gender in older adults. Methods: Data from 5,553 Koreans aged 65 or older were extracted from the Korea National Health and Nutrition Examination Survey. HRQoL was assessed using the EQ-5D tool. Complex sample analysis and decision-tree analysis were conducted using SPSS for Windows version 27.0. Results: The mean scores of the EQ-5D index were 0.93 ± 0.00 in men and 0.88 ± 0.00 in women. In men, poorer HRQoL groups were identified with seven different pathways, which were categorized based on participants' characteristics, such as restriction of activity, perceived health status, muscle exercise, age, relative hand grip strength, suicidal ideation, the number of chronic diseases, body mass index, and income status. Restriction of activity was the most significant predictor of poorer HRQoL in elderly men. In women, the poorer HRQoL groups were identified with nine different pathways, which were categorized based on participants' characteristics, such as perceived health status, restriction of activity, age, education, unmet medical service needs, anemia, body mass index, relative hand grip, and aerobic exercise. Perceived health status was the most significant predictor of poorer HRQoL in elderly women. Conclusion: This study presents a predictive model of HRQoL in older adults according to gender and can be used to detect individuals at risk of poorer HRQoL.

  • Parkinson's disease(PD) is a progressive neurodegenerative disease that affects the functioning of the basal ganglia, a brain area that contributes to the control of movement. The disease is caused by the death of nerve cells in the brain that produce dopamine, a chemical messenger. The cells affected usually produce a neurotransmitter(a chemical that transmits nerver impulses) called dopamine, which acts with acetylcholine, another neurotransmitter, to fine-tune muscle control. In Parkinson's disease, the level of dopamine relative to acetylcholine is reduced, adversely affecting muscle control. When the supply of dopamine is depleted, the function of the basal ganglia is disrupted and its ability to control movement-deteriorates. The result is that PD patients experience moderate rigidity, difficulty in initiating movements and slowness in executing them, and a rhythmical tremor at rest. Although the cause of Parkinson's disease is not known, genetic factors may be involved. About 3 in 10 people with the disorder have an affected family member. About 1 in 100 people over the age of 60 in the US have Parkinson's disease. And Parkinson's disease is slightly more common in men. The course of the disease is variable, but drags may be the best effective in treating the symptoms and improving quality of life. But, The doctor may arrange physical therapy to help with physical mobility problems. It is important to continue to exercise and take care of your general health. Try to take a walk each day. Stretching exercises can help you maintain your strength and mobility. So, This papers will serve about the information of PD for clinical physical therapist. Finally, The aim of review is increasing approach method and technique for PD patients by the view of physical therapy.
