Background: Self-myofascial release using a foam roller has short-term effects for improving muscle function and joint range of motion (ROM) and reducing delayed onset muscle soreness (DOMS) after exercise. Objectives: The purpose of our study was to examine the muscle physiological changes for each set in self-myofascial release of the hamstring muscles using a foam roller in order to provide basic data for the most effective program composition for improving muscle tension, stiffness, and flexibility of the hamstring muscles. Design: A quasi-experimental clinical trial. Methods: To confirm the effect of self-myofascial release of the hamstring muscles using a foam roller, muscle tone and stiffness of the hamstring muscles were measured. As an intervention method, the study subject performed four sessions of self-myofascial release by moving a foam roller back and forth on the posterior thigh muscle of the right leg. Results: There were statistically significant changes in the stiffness of the biceps femoris and the flexibility of the hamstring muscles. Conclusion: Self-myofascial release with foam rolling is an effective intervention method for increasing hamstring flexibility and ROM, and it is recommended as effective to perform self-myofascial release for three to four sessions to maintain normal muscle tone and stiffness of the hamstring muscles.

The purpose of this study was to examine the effects of combined respiratory physical therapy on respiratory function, spinal curve and spinal mobility for community-dwelling elderlies with restrictive lung diseases. In total, 10 patients participated in an 8-week intervention program of thoracic cage mobilization and breathing exercise in combination. The results of the study are as follows: for respiratory function, the forced expiratory volume in 1 second (FEV1), forced vital capacity(FVC), and FEV1/FVC were significantly improved to .30±0.31ℓ, .46±.42ℓ, and 18.10±11.39%, respectively (p<.05). For spinal curve, the thoracic curve and the lumbar curve were improved significantly to -2.20±1.40° and -1.20±1.14°, respectively (p<.01). For spinal mobility, the thoracic flexion (3.40±2.99°), thoracic extension (3.50±1.43°), lumbar flexion (4.50±4.74°), and lumbar extension(- 1.50±1.84°) were all significantly improved (p<.05). These findings indicate that thoracic cage mobilization and breathing exercise in combination improve the respiratory function, spinal alignment, and spinal mobility in elderly people with restrictive lung diseases, Key

왕중산 국제물리치료연구학회 2022 Journal of International Academy of Physical Ther Vol.13 No.3

Background: Height is an important factor in determining a person’s appearance, so people often wear height increase elevator shoes insoles (HIESI) or high heels to make themselves look taller. However, high heels often act as a risk factor for musculoskeletal diseases. Objectives: To investigated how muscle tone and muscle stiffness in the lumbar region of young adult men varied according to the height of the HIESI, and analyzed the correlation. Design: Non-randomised trial. Methods: Muscle tone and muscle stiffness in the upper and lower lumbar regions of 20 healthy young adult men in an upright standing position were measured as the subjects wore no insoles and 2 cm, 3 cm, and 4 cm insoles. Results: Muscle tone and muscle stiffness in the lumbar region did not show a significant change according to the increased height of the HIESI. However, a positive correlation was observed when the subjects wore 4 cm HIESI, as there was a significant increase (P<.05) in muscle tone and stiffness in the left side of the upper lumbar region and in the right side of the lower lumbar region. Conclusion: Wearing HIESI for short periods of time in the static standing position did not cause a change in muscle tone and muscle stiffness in the lumbar region. However, wearing 4 cm HIESI demonstrated a correlation of increased muscle tone and stiffness in the upper and lower lumbar regions in an asymmetric manner.

왕중산,김성태 한국엔터테인먼트산업학회 2022 한국엔터테인먼트산업학회논문지 Vol.16 No.8

This study aims to investigate the major-related work-related musculoskeletal disorders of performing art students and their level of physical self-efficacy, as well as examine the relationship between the two. The study participants were performing art students from a university. In total, 215 data sets were obtained from the participants using a structured self-administered questionnaire. The study results show that the proportion of musculoskeletal symptom(MSS) by body part is highest in the shoulder and the leg/foot (27.0%). The proportion of musculoskeletal disorder(MSD) by body part is highest in the waist (13.5%), followed by the leg/foot (11.2%). Notably, the longer the pain period in the leg/foot, the greater the physical burden (r=220, p=.047),; the higher the pain degree in the leg/foot, the more debilitating the physical burden (r=.236, p=.033). Furthermore, there are positive correlations between all sub-domains of physical self-efficacy. Moreover, when compared to healthy students, students who complained of MSD in the shoulder and waist had significantly lower “physical self-expression confidence” and “physical self-efficacy” (p<0.05). When compared to healthy students, those who complained of MSD in their leg/foot had significantly lower “physical self-expression confidence” (p<0.01). This study finds that developing a prevention program for musculoskeletal problems that is customized for each body part is required for physical and mental health management in performing arts major students.

Background: Junior colleges have been establishing plans for the development of start-up education for students and have been providing various educational programs to support students’ start-up businesses. Objectives: The effects of entrepreneurship and entrepreneurial self-efficacy on the start-up intention of college physical therapy students were analyzed. Design: Questionnaire design. Methods: Surveys on entrepreneurship, entrepreneurial self-efficacy, and start-up intention were conducted with 269 college physical therapy students, and the levels of individual measurement variables, correlations, and variables affecting start-up intention were analyzed. Results: College physical therapy students showed differences in start-up intention between genders, and male students tended to have a higher startup intention (P<.001) than female students. The correlations among the major variables were analyzed. According to the results, all sub-factors of start-up intention had significant positive correlations with all sub-factors of entrepreneurship and entrepreneurial self-efficacy (P<.05). In addition, multiple regression analysis was conducted to identify factors affecting start-up intention. Start-up education was shown to have no direct effect on start-up intention. Innovation (β=.238, P=.000), risk sensitivity (β=.228, P=.000), and initiative (β=.220, P=.001), which are sub-factors of entrepreneurship, were shown to have effects on start-up intention. Self-regulated efficacy (β=-.193, P=.039) and task challenge (β=.210, P=.004), which are sub-factors of entrepreneurial self-efficacy, were found to have effects on start-up intention. Conclusions: To boost the start-up intention of college physical therapy students and induce their start-ups, customized start-up education that considers entrepreneurship level and gender is necessary.

Background: Problem-based learning (PBL) is presented as a superior teaching method compared to existing lecture-based learning. Objectives: To analyzed the effectiveness of creative problem-solving competency, class participation, and self-efficacy in physical therapy students after PBL. Design: Questionnaire design. Methods: This study involved 29 physical therapy students and analyzed changes in their creative problem-solving competency, class participation, and self-efficacy and the correlations between these measurement variables before and after PBL on the “Therapeutic Exercise & Practice” subject. Results: PBL in the musculoskeletal exercise therapy-related subject significantly improved class participation and self-efficacy (P<.05) compared to conventional lecture-based learning, but there was no significant difference in creative problem-solving competency. There was also a positive correlation between a higher level of class participation and higher self-efficacy (P<.05). Conclusions: PBL in the “Therapeutic Exercise & Practice” subject in the Department of Physical Therapy can be an effective educational strategy to increase students’ class participation and self-efficacy. Accordingly, instructors in this department should systematically construct the design of PBL curricula to improve the quality of educational content.

A Comparative Study on the Pulmonary Function between Smoking Soldier and Non-smoking Soldier

왕중산,최명진 국제물리치료연구학회 2018 Journal of International Academy of Physical Ther Vol.9 No.4

Smoking can be a significant cause of lung diseases and reduced respiratory functions. Among soldiers, smoking may have a negative impact on their health (physical strength) and well being. Information on differences in the respiratory functions of smokers and nonsmokers in the military services and the effects of the smoking duration and amount (i.e., the number of cigarettes smoked per day) would be useful. This study investigated smoking durations and smoking amounts among young male soldiers (N = 61). The forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1), and forced expiratory volume in 1 sec/forced vital capacities (FEV1/FEC) were measured FVC, FEV1, or FEV1/FEC of smokers and nonsmokers were not significantly different, and FVC and FEV1 were inversely proportional to smoking duration. Besides, the number of cigarettes smoked per day was not correlated with respiratory functions. These findings may be attributed to the effect of the strenuous physical activity (e.g., military drills) undertaken by soldiers on their respiratory functions. Despite the lack of evidence for a difference in the respiratory functions of smokers and nonsmokers, this study recommends ongoing respiratory function management through smoking cessation programs and respiratory physiotherapy to manage the respiratory functions of Korean smoking soldiers.
