Background: Chronic back pain shows a high correlation with lumbar disability, physical disability for daily activities, and psychosocial factors, such as depression. Object: The purpose of this study was to examine the correlation of the level of pain and disability with psychosocial factors, which are potential disturbance variables, in patients with chronic lumbar pain. Method: The sample included 258 patients, who had complained of chronic lumbar pain for more than three months. The Quadruple Visual Analogue Scale was used to measure the level of pain, and a Korean version of Oswestry Disability Index was used to measure the level of disability. Psychosocial factors were measured using the Tampa scale for Kinesiophobia-11, Fear Avoidance Beliefs Questionnaire, and Pain Self-Efficacy Questionnaire. The collected data was analyzed using PASW 18.0, and an independent samples t-test was used to examine frequency, percentage, mean, and standard deviation of sociodemographic characteristics and major variables. Pearson's correlation coefficient was used to investigate the correlation between the level of pain and disability and psychosocial factors. Stepwise multiple regression analysis was done to determine the level of pain and psychosocial factors of functional disorder. The significance level was set at ${\alpha}=.05$. Result: There is a strong correlation between the level of pain and functional disorder and psychosocial factors in patients with chronic lumbar pain. The study also revealed that as the levels of pain and fear avoidance increase, pain self-efficacy decreases. Conclusion: The results suggest that negative perceptions towards pain, limitations of physical movement, and severe fear avoidance directly affect the decrease in pain self-efficacy. Therefore, it is recommended to test pain self-efficacy when measuring the level of pain and disability in patients with chronic low back pain.

This study aims to analyze the mediating effect of disability level on the relationship between economic activity participation and life satisfaction level of middle-age and older women with disabilities. The survey respondents were 4,961 women with disabilities aged from 45 to 65 who participated in one of the first series of the PSED(2nd to 8th). Results of the analysis showed the economic activities of middle-aged and older women with disabilities and level of disability were correlated with a statistical significance in the analysis phase 1 and 2, and economic activity participation affected life satisfaction level through the level of disability as a parameter, indicating that a mediating effect does exist. This study suggests that to enhance the life satisfaction level of middle-aged and older women with disabilities through participation in economic activities, an employment scheme based on their level of disability is necessary.

Purpose: This study investigated the effects of proprioceptive neuromuscular facilitation (PNF) respiratory muscle strengthening exercise on the pulmonary function, back pain, and disability level of patients with chronic low back pain (CLBP). Methods: There were 24 CLBP patients randomly divided into the experimental group (n = 12) who took part in PNF respiratory muscle strengthening exercise and the control group (n = 12) who performed a mock treatment. Both groups performed their respective interventions for 15 min five times per week for four weeks. The pulmonary function was measured using a portable spirometer. The back pain of the participants was assessed using a visual analogue scale. The Oswestry disability index was conducted to measure disability level. A paired t-test was performed to compare within-group changes before and after the PNF respiratory muscle strengthening exercise. Differences between the experimental and the control groups were analyzed using an independent t-test. For all tests, the level of statistical significance was α = 0.05. Results: The within-group change in pulmonary function was significantly different in the experimental group (p < 0.05), and the levels of back pain and disability were significantly different between the groups (p < 0.05). There was also a significant between-group difference in pulmonary function, back pain, and disability level after intervention (p < 0.05). Conclusion: These results suggest that PNF respiratory muscle strengthening exercise enhances pulmonary function and reduces levels of back pain and disability in patients with CLBP.

The purpose of this study was to examine the influences of disability identity on posttraumatic growth and the moderating effects of resilience on the relationship between the two variables in individuals with acquired disabilities who have experienced the trauma of disability in their adulthood. For the purpose, the study surveyed 203 persons who have acquired a disability after the age of 18 years, and then performed a standard multiple regression analysis and a hierarchical multiple regression analysis respectively using data gathered. The results of the study are as follows. First, a higher disability identity resulted in a higher level of posttraumatic growth. Second, when disability identity and posttraumatic growth were positively related, increasing the level of resilience increased the effect of disability identity on posttraumatic growth. Thus on the basis of the results, the study discussed the tasks ahead to form a positive disability identity and increase the level of resilience.

This study investigates the acoustic-phonetic features and speech intelligibility of Lombard speech in children with intellectual disability, by examining the effect of Lombard speech at 3 levels of non-noise, 55dB, and 65dB. Eight children with intellectual disability read sentences and played speaking games, and their speech were analyzed in terms of intensity, pitch, vowel space of /a/, /i/, and /u/, VAI(3), articulation rate and speech intelligibility. Results showed, first, that intensity and pitch increased as noise level increased; second, that VAI(3) increased as the noise level increased; third, that articulation rate decreased as noise intensity increased; finally, that speech intelligibility increased as noise intensity increased. The Lombard speech changed the VAI(3), vowel space, articulation rate, speech intelligibility of the children with intellectual disability as well. This study suggests that the Lombard speech will be clinically useful for the persons who have intellectual disability and difficulties in self-control.

Purpose : The purpose of this study was to investigate functional disability for the elderly in rural Korea and to identify influencing factors of functional disability. Methods : The data were collected for 76 community-dwelling elderly in rural area and above 65 years. We assessed cognitive function, functional disability, depression using LACLS, WHODAS 2.0, SGDS-K. Data were analyzed using descriptive statistics for general characteristics of subjects, Spearman's correlation among LACLS, SGDS-K, WHODAS 2.0, age, educational levels. And multiple regression was used to find influencing factors of functional disability. Results : As a result of this study, we identified that WHODAS 2.0 total score was 50.59, summary score was 9.94 and functional disability of the elderly in rural area is in the 70^th percentile. The highest level of disability occurred in areas related to 'life activities (household)', 'participation in society' and the lowest level of disability occured in areas of 'self-care', 'getting along with people'. Functional disability was significantly correlated with age (r=.398), cognitive function (r=-.547), depression (r=-.563) but not educational levels (r=-.215). Finally, we confirmed that depression (𝛽=.371), cognitive function (𝛽=-.263), widowed status (𝛽=.303), age (𝛽=.272), non-participation of community program (𝛽=.165) was significantly influencing factors of functional disability and the explanatory power of these factors was 52.80 %. Conclusion : This study revealed important factors of functional disability. Therefore, we need to consider these factors when we developed program related to health for the elderly (aged > 65 years) in rural Korea. Further, we need to standardize WHODAS 2.0 in order to enhance its applicability in clinical practices.

Background: Sleep disturbance and depression are becoming more recognized as important symptoms among individuals with chronic low back pain. This study evaluated the effect of stabilization exercise on pain-related disability, sleep disturbance and the psychological status of patients with non-specific chronic low back pain (NSCLBP). Methods: A total of 26 patients (M/F = 17/9) with NSCLBP with a mean age of $50.0{\pm}15.5$ took part in this study. Participants were recruited from selected hospitals in Lagos state. Ethical approval was sought and obtained from the health research and ethics committee of Lagos University Teaching Hospital Idi-araba, Lagos, Nigeria. Participants performed stabilization exercise for eight weeks consecutively and were assessed for pain-related disability, anxiety, depression, and sleep disturbance using the pain-disability index, hospital anxiety and depression scale, and the insomnia severity index at baseline, the 4th week, and the 8th week, postintervention. Results: The participants studied recorded significant reduction in pain-related disability (P = 0.001). There was also improvement in the sleep quality (P = 0.001), depression level (P = 0.001), and anxiety level (P = 0.001), post intervention. Conclusions: This study revealed that stabilization exercise is very useful in the management of sleep disturbance, pain-related disability, depression, and anxiety in NSCLBP patients.

This study examines the effects of chronic disease/disability and stress from health on depressive symptoms among one-person households living in Seoul and Gyeonggi Province in Korea. This study also investigates the moderating effect of social support on the relationship between 1)having a chronic disease/disability and depressive symptoms as well as 2)stress from health and depressive symptoms. This study used data from an online survey targeting one-person households living in Seoul and Gyeonggi Province. The final sample included 499 one-person households. Using a multiple regression analysis with SPSS 20.0, results showed that having a chronic disease/disability was associated with a higher level of depressive symptoms. In addition, stress from health was associated with a higher level of depressive symptoms. In regard to the roles of social support, economic support and emotional support had a direct negative effect on depressive symptoms. Emotional support had a moderating effect on the relationship between having a chronic disease/disability and depressive symptoms. In addition, emotional support also had a moderating effect on the relationship between stress from health and depressive symptoms. Based on these findings, this study suggests that policy makers should reduce the economic burden from a chronic disease/disability and help one-person households to strengthen their social support network.

The purpose of this study is to investigate the factors associated with the incidence and the transition of disability among Korean older adults. Samples consist of 1,454(42.7%) men and 2,032(58.3%) women aged 65 and over who participated in the 1st and 2nd wave of the Korea Longitudinal Study of Aging: KLOSA. To estimate the level of disability, ADL and IADL disability indexes are used. As the results, major risk factors for ADL/IADL disability incidence include injury, vision problem, cognitive function, depression, health behavior, socioeconomic characteristics and age. Among the normal older adults, the odds ratio of having dementia symptoms at 2nd wave(2008) are 2.0 times greater for the older adults who have less cognitive function than those who don't have at 1st wave(2006). Among the older adults with chronic diseases, the odds ratio of having disability at 2nd wave are 1.8 times greater for the older persons who have depression than those who don't have at 1st wave. Secondly, concerning the predictors affecting the disability transition among the disabled older adults at 1st wave, the likelihood of remaining at the same level or deteriorating the level of IADL disability, as compared with improving the level, is associated with having less instrumental support or being older. These results indicate that it is necessary to prefer multilevel intervention in order not only to prevent the incidence of disability, but also to prolong the deterioration of disability in the older adults.

Purpose: The purpose of this study was to examine the factors affecting of health screening among persons with disabilities. Method: The study examines the factors affecting of health screening using over 20 years of age who participated in the 2017 National survey of the disabled data. Subjects were 6,332 person with disabilities over 20 years of age. Data were analyzed using descriptive statistics, X2-test, multiple logistic regression with the SPSS win 21.0 program. Results: Health screening among persons with disabilities is differentiated with education level, marital status, Subjective House economic status, Health insurance, Economic activity, Type of disability, Grade of disability, Stress recognition, Depressive symptom, Suicidal thinking, Suicidal attempt, and grade of disability. The significant predictors of the health screening were age, Subjective House economic status, Economic activity, and Grade of disability. Conclusion: We should consider age, disability level, and economic level when developing a screening program for people with disabilities. Especially, the development and promotion of the health screening program for persons with disabilities and related education are required.
