Abnormalities in lumbopelvic rhythm (LPR) play a role in occurrence/recurrence of low back pain (LBP). The LPR before spinal fusion surgery and its changes following the surgery are not understood. A repeated measure study was designed to investigate timing and magnitude aspects of LPR in a group of patients (n = 5) with LBP before and after a spinal fusion surgery. Participants completed a forward bending and backward return task at their preferred pace in the sagittal plane. The ranges of thoracic and pelvic rotations and lumbar flexion (as the magnitude aspects of LPR) as well as the mean absolute relative phase (MARP) and deviation phase (DP) between thoracic and pelvic rotations (as the timing aspects) were calculated. Thoracic, pelvic, and lumbar rotations/flexion were respectively 2.19° smaller, 17.69° larger, and 19.85° smaller after the surgery. Also, MARP and DP were smaller during both bending (MARP: 0.0159; DP 0.009) and return (MARP: 0.041; DP: 0.015) phases of the motion after surgery. The alterations in LPR after surgery can be the result of changes in lumbar spine structure due to vertebral fusion and/or new neuromuscular adaptations in response to the changes of lumbar spine structure. The effects of altered LPR on load sharing between passive and active components of lower back tissues and the resultant spinal loads should be further investigated in patients with spinal fusion surgery.

Currently a lack of guidelines for Criterion B of the DSM-IV-TR (American Psychiatric Association, 2000) hampers diagnosis of children with developmental coordination disorder (DCD). The Performance of Activities of Daily Living Questionnaire (PADL-Q; Dewey, Larkin & Summers, 2004) is a new parent-reported instrument developed to quantify the level of interference in activities of daily living (ADL) experienced by children with DCD and was tested for its efficacy in addressing Criterion B. Thirty-two children aged between 5 and 10 years comprising two matched groups, 16 with DCD (8 boys and 8 girls) and 16 without DCD (8 boys and 8 girls) participated in the study. The aim of the research was to investigate the ability of the PADL-Q to identify differences between children with and without DCD. A further 5 children, in the same age range, who did not have DCD added data that was used to ascertain relationships between the constituent assessments. All children were tested using the MAND (McCarron, 1982) whilst their parents completed the PADL-Q. A set of Tests of Activities of Daily Living (TADL) tasks were devised for the children to perform that further validated parents ratings of children?s ADL performance. A Group x Gender MANCOVA, controlled for age, of the PADL-Q total scores demonstrated that there was a significant difference between the children with and without DCD (F(3,25) = 9.44, p < .001; Wilks' lambda = 0.47). Follow-up univariate tests showed a Group x Gender interaction and simple main effects of this interaction indicated that the PADL-Q did not discriminate between the DCD and non-DCD boys. The ability of the PADL-Q to identify DCD was explored in the concurrent validity against the MAND when using a diagnostic cut-off point. The PADL-Q demonstrated 100% specificity and positive predictive values but only 19% sensitivity and 62% negative predictive values. There was a moderately strong relationship (r = .71), between the PADL-Q total score, considered a measure of Criterion B, and the MAND, a measure of Criterion A (DSMIV- TR, 2000). A two factor (Group x Gender) ANCOVA, controlled for age, of the TADL items revealed a statistically significant effect for DCD only (F(1,19) = 34.65, p < .001). There was a moderate correlation (r = -.64) between the PADL-Q total score and the TADL tasks, indicating that parent-reports are supported by their child?s performance. The PADL-Q appears to have potential as part of the DCD diagnostic process; however, further refinement on a larger sample is necessary before it can be used as an easily-administered guide to ADL performance levels in children.

Doctor of philosophy (PhD) / Abstract As one of the most culturally diverse countries in the world, Australia has a high proportion of minority communities. However, its ageing population, particularly within these ethnic minorities, faces a range of barriers or difficulties in gaining access to and using health and aged care services. This study aims to identify the acculturation factors that affect the health status of Iranian-born elderly immigrants to Australia and their utilisation of health and community aged care services. The results of this study will be of value to Iranian elders, their families, and Australian aged health care service providers. The findings could also contribute towards enriched multicultural policy and improved social fairness, access to services, and equity for the aged from different ethnic backgrounds. 302 Iranian migrants aged 65 years who had lived in the Sydney Metropolitan area for at least six months were surveyed via a written questionnaire, face-to-face interviews, and telephone interviews. The results were analysed using SPSS and then compared to the findings from a 1999 survey of NSW elderly. The results indicate that Iranian migrants suffer higher levels of psychological distress and are more limited in their physical functioning than the general population of older Australians. They are in greater need of assistance with activities of daily living, have a lower sense of wellbeing, and are far less likely to utilise aged care services. Iranian migrant who do not speak English at home experience these disadvantages to an even greater extent English language proficiency was the only acculturation factor found to affect whether Iranian elderly utilised health and community aged care services, while ability to engage in activities of daily living (ADL) was the only health variable associated with their utilisation of community supportive aged care services. This variable did not predict the use of community aged care services in the broader sample of NSW respondents. Since limited proficiency in English placed elderly Iranian migrants at greater health risk and impeded their access to necessary assistance, the findings suggest that they would clearly benefit from English classes and from access to health and community care services and information regarding these services in the Farsi language.

<p>The overall aim was to study and gain knowledge about what it means to live with muscular dystrophy and to study rehabilitation from the patient's perspective, among adults with muscular dystrophy in three Swedish counties: Örebro, Östergötland and Norrbotten. The thesis comprises two qualitative and three quantitative studies. Thirty interviews about illness experience were subjected to content analysis and 37 interviews about perceived support in rehabilitation were analysed according to phenomenological guidelines. Data were also collected by the Assessment of Problem-focused Coping (APC), the ADL Staircase, the Self-report ADL, the Mental Adjustment to Cancer Scale, the Sickness Impact Profile, the Psychosocial well-being questionnaire and the Quality of Life Profile. The APC was developed for assessment of problem-focused coping and also covers questions concerning the extent to which activities are experienced as problems and satisfaction with activities. The result shows that the experience of illness is largely similar in the three diagnostic groups (proximal MD, Myotonic muscular dystrophy, Myopathia distalis tarda hereditaria). The persons reported many restrictions of everyday activities, most often in mobility and transportation. Over half were dependent on other people in activities of daily living, and the illness was experienced mainly as having negative consequences for everyday life. A lower quality of life may be partly explained by a reduced capacity for activities. Problem-focused coping was used only to a limited extent, and 'Fighting spirit' was the dominant coping strategy. Rehabilitation was experienced as very valuable, particularly the education about the muscle disease, technical aids, grants and physical training. Over a five-year period, disability and quality of life of the study participants deteriorated significantly, and the dependence on other people increased. </p>

A comprehensive understanding is lacking of the experiences persons with acquired physical disabilities have of changes in their engagement in occupations and of the conditions influencing these experiences Furthermore, little is known about the experiences these people have of the rehabilitation process and whether the rehabilitation services satisfy their needs. Access to such knowledge would significantly add to the ability to design rehabilitation services intended to enhance participation in everyday life. The overall aim of this thesis was, therefore, to illuminate and enhance the understanding of how persons with acquired physical disabilities experienced their rehabilitation process and their possibilities to engage in occupations in everyday life. The thesis is comprised of five studies. The planning of the clients’ rehabilitation at hospital was explored through interviews with the clients (n=57) and the professionals (n=50). Interviews exploring how persons with physical disabilities experienced their rehabilitation process (n=15), their occupational lives in their homes (n=13) and the use of assistive devices (n =17) were analysed qualitatively. Data was also collected from persons with spinal cord injury (n =161) by the Impact on Participation and Autonomy questionnaire. The findings showed that the professionals used different strategies to encourage the clients to participate in the planning of the rehabilitation and that the strategies were based on traditions rather than on the individual clients’ desires to participate. The informants’ experiences reflected three parallel chains of rehabilitation over a period of time, a medical, a psychological and a social one. The influence of the different rehabilitation chains on how the clients’ lives turned out varied over time, and the professionals were predominantly involved in the medical rehabilitation chain. The informants’ experiences showed that their engagement in occupations in the home differed profoundly. Access to social support, which was provided under different conditions, was of decisive importance for their occupational engagement. The findings also showed that changes in the informants’ occupations in the home setting transformed the meaning of the home in general. The meaning of using assistive devices was experienced as manifold and double-edged. The incorporation of or resistance to assistive devices was understood as different approaches to adaptation with the same intention: to achieve desired occupational self-images. The majority of the informants perceived their participation in the life situation as sufficient but more than half reported one or more severe problems with participation. Access to social support in everyday occupations had a greater impact on predicting severe problems with participation than certain traditional health related factors or aspects related to the individual. To conclude, the findings indicate that the rehabilitation services need to be better able to adapt to clients’ desires to participate in the planning of their rehabilitation, and designed to satisfy the various needs the clients experience throughout the rehabilitation process. It was revealed that the societal and social environment, as manifested through social interactions, are of central importance in understanding the consequences of and possibilities to engage in occupations supporting participation in everyday life.

The purpose of this thesis was to examine coronary heart disease (CHD) risk factors and secondary complications in individuals with spinal cord injury (SCI). In particular, this thesis was organized around the central theme of adiposity, which is a prevalent complication following SCI. Study 1 focused on understanding the relationships between activities of daily living (ADL) and CHD risk factors including central adiposity, lipoproteins, and triglycerides. Using generalized linear models, while controlling for pertinent covariates such as sex, age, and leisure time physical activity (LTPA), it was found that Mobility ADL (wheeling and transferring) were negatively associated with total and LDL-cholesterol. Study 2 examined whether individuals who considered themselves to be overweight subsequently had less favourable subjective well-being, and were more likely to report specific secondary complications than individuals who did not consider themselves to be overweight. Logistic regression analysis and partial correlations controlling for pertinent covariates such as sex, age, and injury severity, revealed that individuals who considered themselves to be overweight reported greater pain, depression, overuse injuries, and fatigue, and less satisfaction with life than individuals who did not consider themselves to be overweight. In summary, the findings suggest that a) participation in specific types of ADL (i.e. Mobility ADL) are associated with a lower CHD risk and should be further explored and that b) elevated perceived adiposity is associated with specific secondary complications and lower subjective well-being. Overall thesis findings support the overwhelming evidence of the benefits of daily physical activity and maintaining a healthy bodyweight in the SCI population. / Thesis (Master, Kinesiology & Health Studies) -- Queen's University, 2009-05-28 11:40:32.574
