Purpose: The aim of this study was to compare trunk and lower extremity muscle activity during deadlift on stable - and unstable surfaces. Methods: Twenty healthy men participated in this study. The participants performed deadlift exercise on both a stable surface and an unstable surface. During the deadlift, the activities of the trunk and lower extremity muscle were collected by using electromyography. Results: The results showed that the electromyographic activity of the gluteus maximus significantly increased during deadlift on an unstable surface compared to on a stable surface (p <0.05). However, in the electromyographic activities of the rectus femoris, biceps femoris, and erector spinae, there were no significant differences (p >0.05). Conclusion: The finding that the electromyographic activity of the gluteus maximus increases significantly during deadlift on an unstable surface compared to stable one could be used to develop an efficient exercise program.

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.

Purpose: The purpose of this study is to provide basic evidence on the need to approach osteoarthritis patients through a psychological factors-considering rehabilitation program by understanding how activity restrictions in osteoarthritis affect health-related quality of life and depression. Methods: This study assessed 3,761 osteoarthritis patients from the Korea National Health and Nutrition Examination Survey. The subjects were divided into two categories: with and without activity restriction. Results: The prevalence of osteoarthritis in women was higher than that of men (men: 19.7%; women: 80.3%), and high BMI increased the prevalence of osteoarthritis. The EQ-5D index of subjects with activity restriction was 0.84±0.18 (points), while in those without activity restriction was 0.93±0.12, and the diagnosis of depression was 15.8%, 8.2%. There was a statistically significant difference in the odds ratio for each item in the EQ-5D. Moreover, the odds ratio for depression with activity restriction was 2.098 compared with no activity restriction. Conclusion: Activity restriction of osteoarthritis patients significantly decreases the health-related quality of life and increase the probability of depression. Therefore, early diagnosis of depression symptoms to prevent deterioration of symptoms in patients with osteoarthritis and to increase compliance with rehabilitation treatment, and to provide arbitration, including treatment that can alleviate depression.

Purpose: This study aimed to provide a scientific basis for effects of the push-up plus exercise program on scapular position and on muscle activity in individuals with rounded shoulder posture (RSP). Methods: The supine method was applied to 46 potential subjects, of which 30 with RSP were selected. Subjects with RSP were divided into two groups: a gender push-up plus group as the experimental group a pectoralis minor self.stretch group as the control group. RSP data after 4 weeks of each intervention were obtained and analyzed to measure the activities of the 3 muscles. Results: The two groups differed significantly with regard to EMG changes in the serratus anterior (p<0.05). The EMG results indicated a significant reduction in the activity of the upper trapezius in the experimental group (p<0.05). EMG results indicated a significant increase in the activity of the serratus anterior after the intervention (p<0.05). EMG results of the subjects in the control group indicated that the activity of the upper trapezius significantly decreased (p<0.05). The RSP values of the subjects in both groups were significantly decreased (p<0.00). Conclusion: An improvement in the strength of the serratus anterior, and in the stretch effectiveness of the pectoralis minor, as well as changes in the scapular position were observed after 4 weeks of push-up plus exercise by the subjects.

PURPOSE: This study was to evaluate the muscle activity of gluteus medius, tensor fascia latae, and quadratus lumborum during side-lying abduction exercise in various pelvic tilting positions. METHODS: We measured the activity of three muscles in three pelvic tilt positions for 17 normal subjects with performing the side-lying hip abduction. Three pelvic tilt positions were posterior tilt, neutral tilt and anterior tilt. We used the mean value after participants performed the hip abduction three times each position. RESULTS: The activity of gluteus medius within three pelvic positions showed the highest activity in pelvic posterior tilt position and the lowest in pelvic neutral tilt position (p = .04). The activity of tensor fascia latae showed the lowest in pelvic posterior tilt position and the highest in pelvic posterior tilt position (p = .00). The activity of quadratus lumborum revealed the lowest activity in pelvic neutral tilt position and the highest in pelvic anterior tilt position (p = .00). The activity of selective gluteus medius activation according to pelvic displacement showed the highest activity in pelvic neutral tilt position and lowest in pelvic anterior tilt position (p = .00). CONCLUSION: Hip abduction with Pelvic posterior tilt position may be effective in increasing gluteus medius and may be effective in strengthening exercise program for the gluteus medius. In addition, Hip abduction with pelvic neutral position may have an effect on the selective gluteus medius, which is considered to be effective in the exercise program for muscle reeducation training of the gluteus medius.

Purpose: The paper presents an intervention for clinical applications in the future by examining the effects of 3D stabilization exercise on patients with lumbar instability, which causes problems in the muscles and balance, and analyzing the effects of balanced lumbar muscles on the static balance. Methods: After collecting samples randomly from thirty patients with lumbar instability, fifteen patients selected for 3D stabilization exercise were placed in the stability group and fifteen patients selected for Swiss ball exercise were placed in the ball exercise group. The intervention program was applied for thirty minutes a session, once a day, three days a week for four weeks. Before the intervention, the lumbar muscle activity and static balance were measured. After four weeks, they were re-measured in the same way and the data were analyzed. Results: In relation to the within-group changes in muscle activity, all groups except for the LEO and REO groups showed significant differences. Regarding the between-group changes in muscle activity depending on the left and right difference, ES, RA, and TrA but not EO showed significant differences. In addition, there were significant differences in the between-group change in static balance. Conclusion: 3D stabilization exercise improves the muscle activity by promoting a balanced posture of lumbar muscles and changing senses, such as a proprioceptor but this had a positive influence on the static balance by controlling the balance of muscles.
