The Development And Testing Of An Instrument For Measuring Awareness Of Coronary Heart Disease Risk Factors Reduction In A Hong Kong Chinese Population, Choi Wan Chan Dec 2008

The Development And Testing Of An Instrument For Measuring Awareness Of Coronary Heart Disease Risk Factors Reduction In A Hong Kong Chinese Population, Choi Wan Chan

Theses

Coronary heart disease (CHD) claims millions of lives every year worldwide. In the developed countries, a clear connection has been documented between a decline in CHD mortality and modifiable risk factor reductions. While raising awareness of CHD risk factors reduction is imperative, no valid instrument backed by robust psychometric data is available to measure people's awareness in this regard. In addition, especially among the Chinese population, despite many studies already conducted concerning awareness of CHD-related issues, inconsistency in how people define and measure this concept remains. This study aimed to develop a valid instrument that measures Hong Kong Chinese ...


Exploration Of Differences In Vertical Jump Performance Between Typically Developing Children And Those Identified With Dcd: A Kinematic And Kinetic Analysis, Morgan Williams Jun 2008

Exploration Of Differences In Vertical Jump Performance Between Typically Developing Children And Those Identified With Dcd: A Kinematic And Kinetic Analysis, Morgan Williams

Theses

This study compared the motor performance of children identified with Developmental Coordination Disorder (DCD) with those of a matched group categorised as typically developing (TD). Based on the existing literature, vertical jumping was the task selected as it is a fundamental movement skill (Gallahue & Ozmun, 2002), and a single optimal coordination pattern has been shown to exist (e.g., Bobbert & van Ingen Schenau, 1998).Within the conceptual framework developed for this enquiry, jump height, the performance outcome, was the highest level variable. Level 2 variables described the centre of mass displacement at key instants during the jumping movement. Level 3 variables identified measures of velocity, force and power, which underpin the movement, and level 4 variables described the countermovement specific to this task. This provided a more thorough analysis than previously reported in DCD literature for jumping. The objective of this study was to identify possible mechanisms of DCD in order to advance the understanding of this impairment. A cross-sectional sample (n = 165) of males and females aged between 5 and 12 years was drawn from a school in Victoria, Australia. Using the Movement-Assessment Battery for Children (M-ABC), 62 children from the sample were identified as having DCD with total impairment scores below the 15th percentile for their age-band (Henderson & Sugden, 1992). From the remaining children assessed, who all scored above the 15th percentile, 62 were matched with the DCD group to form the TD group (n= 62). Participants performed three maximal vertical jumps, standing on a single forceplate. Each child's best vertical jump was analysed using forceplate (700 Hz) and 2D sagittal kinematic data from a single camera video (50 Hz) capture. The results confirmed previous findings that DCD children jump lower than their TD peers, although there was a considerable overlap in motor ability between the groups.;Peak VCOM occurred earlier in the jumping movement in the DCD group, when compared to the TD group. This meant a longer elapsed time from the instant of peak VCOM to take-off, which was attributed to coordination error. The earlier occurrence of peak VCOM in the DCD group could be explained by the lower shank angular ...


Electromyography Of The Trunk And Abdominal Muscles In Golfers With And Without Low Back Pain [Accepted Manuscript], M. H. Cole, P. N. Grimshaw Jan 2008

Electromyography Of The Trunk And Abdominal Muscles In Golfers With And Without Low Back Pain [Accepted Manuscript], M. H. Cole, P. N. Grimshaw

Faculty of Health Sciences Publications

Twelve male golfers who experienced low back pain (LBP) whilst playing or practicing golf and 18 asymptomatic golfers were recruited and divided into handicap-specific groups; low-handicap golfers, with a handicap between 0 and 12 strokes; and high-handicap golfers, with a handicap of between 13 and 29 strokes. The myoelectric activity of the lumbar erector spinae (ES) and the external obliques (EO) was recorded via surface electromyography (EMG), whilst the golfers performed 20 drives. The root mean square (RMS) was calculated for each subject and the data for the ES and EO were normalised to the EMGs recorded whilst holding a ...

Background  Community views, expressed in social impact assessments and collected through community consultation, should play an important role in health technology assessment (HTA). Yet HTA methodologists have been slow to include outcomes of these forms of inquiry in analyses, in part because collecting community views is time-consuming and resource intensive.

Objective  To explore how community views sourced from published studies, grey literature and informal internet web pages can inform HTA.

Methods  A technology reviewed by Adelaide HTA in 2004 was selected: retinal photography for detection of diabetic retinopathy. Published literature, ‘grey’ literature and informal web pages were searched to examine ...

Trunk Muscle Onset And Cessation In Golfers With And Without Low Back Pain [Accepted Manuscript], M. H. Cole, P. N. Grimshaw Jan 2008

Trunk Muscle Onset And Cessation In Golfers With And Without Low Back Pain [Accepted Manuscript], M. H. Cole, P. N. Grimshaw

Faculty of Health Sciences Publications

The knowledge of the onset and cessation timing of the paraspinal muscles that surround the lumbar spine is an important area of research for the understanding of low back pain. This study examined the timing of the erector spinae and external oblique muscle activity in a group of golfers with and without low back pain. The study compared the results of surface electromyography measurements for two groups of golfers. Twelve male golfers who had reported a mild or greater level of pain in the lower back that was experienced while playing golf were examined. A further fifteen male golfers who ...
