Low back pain (LBP) is a common complaint and health problem in Hong Kong, particularly among middle-aged individuals. LBP is the main cause of chronic disability which significantly affects the daily life activities of patients. Pain might result in repeated hospital admissions and subsequently increase the burden on health care providers in Hong Kong. LBP has an enormous effect on quality of life and therefore deserves research attention. Growing evidence shows that yoga may help reduce the level of chronic LBP in adult patients. However, no systematic review has been conducted to support the translation of this theory into practice. Therefore, this thesis aims to evaluate the current evidence on the efficacy of yoga in reducing chronic LBP among adult patients to achieve the following objectives: formulate an evidence-based protocol on yoga practice, assess the implementation potential of the formulated protocol, and develop implementation strategies and evaluation plan for the use of this protocol in a local public hospital in Hong Kong. Five databases were used for the systemic review of relevant studies. These databases were those of Cochrane Library, CINAHL Plus, PudMed, British Nursing Index and Medline (Ovid). A total of eight papers (randomized controlled trials) fulfilled the inclusion criteria of this study. The Scottish Intercollegiate Guidelines Network (SIGN) was used to extract the data and evaluate the paper quality. The findings of the selected papers indicated that yoga practice has a significant effect on reducing pain among adult patients with chronic LBP. The innovation is proposed to be conducted in an adult orthopedic and traumatoloy (O&T) ward. Evidence-based yoga guideline is developed to guide nurses in the effective implementation of the protocol. The SIGN grading system is chosen to grade the recommendations in the guideline. Adult patients with persistent LBP longer than three months are the target population. All study participants practice specific yoga postures under the supervision of yoga instructors and trained nurses in the outpatient clinic. These patients continue home practice for 30 minutes daily or at least twice a week. Based on the findings of the reviewed literatures and the adaptation of these findings into the proposed innovation, the feasibility of implementing evidence-based yoga guideline in the local clinical setting in Hong Kong is demonstrated. An effective communication plan is developed to gain support from stakeholders and efficiently implement the innovation. A two-month pilot study is designed to test the feasibility of the guideline. Pain level, which is the primary outcome of the study, is measured by using Pain Numerical Pain Scale (NRS). Evaluation will be completed after the pilot test and at the end of the whole programme and refinement of the protocol will be accomplished according if necessary. Protocol effectiveness will be determined by a decrease in back pain level after practicing yoga. Other outcomes include the knowledge and satisfactory level of the staff with regards to the protocol, as well as and the costs and benefits of program implementation. / published_or_final_version / Nursing Studies / Master / Master of Nursing

Motivation Impairments of attention and memory are detectable in early psychosis, and often result in severe, longstanding functional impairments. Pharmacological interventions for cognitive impairments have been largely unsuccessful. The current study aims to explore the effects of aerobic exercise and mind-body exercise (yoga) on cognitive functioning and clinical symptoms in female patients with early psychosis. The potential neuromechanism underlying the clinical consequences was also investigated. Methods Female patients (n=120) diagnosed with schizophrenia spectrum disorders, brief psychosis, psychosis NOS, or delusional disorder (according to SCID) were recruited from three hospital/clinic sites. They were randomized into integrated yoga therapy group, aerobic exercise programme group, and waiting list as the control group. Both interventions were held three times weekly. At baseline and at 12 weeks, clinical symptoms, cognitive functions, quality of life and fitness levels were assessed in all participants, and completed structural MRI data were collected in 58 patients. Repeated measures ANOVA and ANCOVA analyses of the clinical, cognitive, quality of life and fitness data were compared between baseline and at 12 weeks among the three groups. Post-hoc Bonferroni test was used for comparing between two groups. Structural MRI data was analyzed by FreeSurfer V5.1 and Qdec V1.4 to calculate the brain volume and cortical thickness. Results Completed clinical and cognitive data were collected in 85 patients, and completed MRI imaging data of good quality were collected in 39 patients. No significant differences in age, education years, and duration of the illness at baseline were observed among the three groups. Both yoga and aerobic exercise groups demonstrated significant improvements in verbal encoding (p<0.01), short-term memory (p<0.05), long-term memory (p<0.01), and working memory (p<0.01) with moderate to large effect sizes compared to control groups. The yoga group showed significantly enhanced attention and concentration (p<0.05). Both yoga and aerobic exercise significantly improved overall clinical symptoms (p<0.05) and depressive symptoms (p<0.05) after 12 weeks. Significant increases were observed in the thickness of the left superior frontal gyrus and the right inferior frontal gyrus (pars triangularis) in the aerobic exercise group. Significant increases were observed in the volume of the postcentral gyrus and the posterior corpus callosum in the yoga group. There was a statistically significant correlation between improvements in working memory and changes in the postcentral gyrus (r=0.54, p<0.01) after controlling for the multiple comparisons with a Bonferroni adjusted alpha level. Discussion Both types of exercise improved memory in early psychosis patients, with yoga having a superior effect on attention than aerobic exercise. Observed increments in the cortical thicknesses and volume may indicate improved neurogenesis. Significance There have been few systematic clinical trial studying exercise and psychosis, and none of them has explored the effects of exercise in female patients with early stage psychosis. The present study indicates possible interventions for cognitive impairments in the patients with early psychosis, which are non-invasive and mostly safe. The application of yoga and aerobic exercise as adjunct treatments to treat psychosis in the clinical setting should be advocated. / published_or_final_version / Psychiatry / Doctoral / Doctor of Philosophy

Background: A study of the impact of yoga and aerobic exercise and psychosis was conducted in 2012 by Lin et al., from The University of Hong Kong. The study indicated significant improvement in the aspects of physical fitness, cognitive functions, psychosocial and emotional functioning in patients with psychosis after a 12-week yoga or aerobic intervention program. Long-term effect of exercise intervention, however, had yet been determined. The aim of the present study was to evaluate the long-term effects of yoga and aerobic exercise on cognitive functioning and clinical symptoms in early psychosis. Patients who originally participated in Lin et al.’s 2012 study were recruited and re-assessed in this current 18-month follow-up study. Methods: Two intervention groups (yoga and aerobic exercise group) and one control group (wait-list control group) of a total 57 subjects from the initial study were recruited in this follow-up study. Cognitive functioning and clinical symptoms were assessed at three time points (T1:Baseline, T2:12-week, T3:18-month). Results: No significant changes or significant deterioration were found in cognitive functioning, clinical symptoms and depression between T2 (12-week) and T3 (18-month) in both intervention groups (yoga and aerobic group). Significant improvement of clinical symptoms was observed in wait-list control group at T3. Conclusions: Although there is no significant finding in this current study, it is still recommended that further study on the relationship between physical exercise intervention and psychosis should carried out in order to explore other adjunct, and especially low cost, treatment to antipsychotics in treating people with psychosis. / published_or_final_version / Psychological Medicine / Master / Master of Psychological Medicine

The intent of this research was to determine if participation in regularly offered Hatha Yoga or Effective Interpersonal Relationship Development classes for the duration of a university quarter (ten weeks) could produce a change in self-concept.Self-concept was defined as the total collection of attitudes, judgments and values which an individual holds with respect to behavior, ability, body, and worth as a person; i.e.self-perception and self-evaluation. Specifically, self-concept was defined as that entity which is measured by the self-report of the discrepancy between perceived self and ideal self using the Index of Adjustment and Values.Data for the study were collected from 215 female students enrolled in a mid-western university who volunteered to participate and who completed the self-concept measure (Bills Index of Adjustment and Values) at the beginning and end of the quarter. There were 54 female students in 3 Yoga classes, 53 in 3 Effective Interpersonal Relationship Development classes and 53 in 4 comparison classes (randomly selected algebra classes). Experimental treatment consisted of material which was normally taught in the classes. Information such as age, quarter in school and other subjects taken was collected with a demographic survey.A second group of 55 female students in 3 Hatha Yoga classes taught the following year completed the pretest and posttest self-concept measures, and also answered a Student Opinion Questionnaire.Analysis of variance of the pretest data across all classes and groups indicated no significant differences, providing an assumption of equivalence of the groups. Repeated measures analysis of variance showed a significant difference on the self-concept measure between the pretest and posttest data (p =.015). The test for simple main effects indicated that only the Hatha Yoga group contributed significantly (p =.01) to the results.Individual group repeated measure analyses indicated significant change in self-concept for the Hatha Yoga group (p =.006) but not for the Effective Interpersonal Relationship Development group (p =.08), although there was a tendency toward a positive self-concept change, or for the comparison group (p =.36). A significant difference between the pretest and posttest also found for the second Hatha Yoga group (p =.043). The majority of students who answered the Student Opinion Questionnaire felt that participation in the Hatha Yoga class had helped them become more self-aware, to feel better about themselves and to solve personal and/or physical problems.

A dissertation submitted in partial fulfillment of the requirements for the degree of Master of Arts (Clinical Psychology) in the Department of Psychology University of Zululand, South Africa, 2005. / HIV/AIDS has reached alarming proportions in South Africa, with many people's lives being affected. This research project looked more closely at caregivers involved in HIV/AIDS work, examining their stress levels and their psychological well-being. A yoga intervention program was implemented with a sample of caregivers at the Holy Cross Hospice, Emoyeni, in Zululand. The effectiveness of the program was evaluated using both qualitative and quantitative measures. Overall, this yoga intervention program was effective with many of the caregivers reporting noted improvements in their stress levels and psychological well-being.

The present study sought to more rigourously explore outcomes of psychological well-being immediately following a psychotherapeutic yoga class. Specifically, the study hypothesized improvements in state anxiety and subjective well-being as well as an observable relationship between state and trait mindfulness following a yoga intervention, all while controlling for differences between yoga instructors, prior yoga experience, and participant endorsements of psychological symptoms. Previous yoga experience was not found to be a significant factor in any of the tested hypotheses. Findings revealed that psychotherapeutic yoga decreased anxiety and increased subjective well-being, even after controlling for therapist variability, prior yoga experience, and client diagnosis. Results also indicate differential impacts on decreased anxiety and increased subjective well-being by class instructor. This is the first study to examine outcomes of an ongoing yoga based-practices in the naturalistic setting of an outpatient counseling center while rigorously controlling for confounding factors (e.g. therapist variability). Methodological and statistical limitations are discussed in depth, and future directions to improve on this study and clarify the present findings are emphasized.

The aim of this study was to explore the influence of yoga on learners with ADHD. In order to reach the aim of this study, an initial literature study was executed to describe ADHD and the practice of yoga. Particular aspects such as concentration, anxiety, self-esteem and aggression were highlighted. Semi-structured interviews with parents, teachers, learners and one yoga instructor were used to conduct the empirical study. Valuable data was also collected from the learners using projection tests and self-esteem questionnaires. Assessments were conducted at two points: during the situation analysis and at the outcome of the yoga intervention. Based on the data collected and analysed, findings were made and conclusions were drawn regarding the influence of yoga on learners with ADHD focusing on the aspects of concentration, anxiety, self-esteem and aggression. Recommendations for future research were then proposed. / Psychology of Education / M. Ed. (Guidance and Counselling)
