Accelerometer-Based Step Regularity Is Lower in Older Adults with Bilateral Knee Osteoarthritis
To compare the regularity and symmetry of gait between a cohort of older adults with bilateral knee osteoarthritis (OA) and an age and sex-matched control group of older adults with healthy knees.
Fifteen (8 females) older adults with knee OA (64.7 ± 6.7 years) and fifteen (8 females) pain-free controls (66.1 ± 10.0 years) completed a 9-min. walk at a self-selected, comfortable speed while wearing a single waist-mounted tri-axial accelerometer. The following gait parameters were compared between the two groups according to sex: mean step time, mean stride time, stride and step regularity (defined as the consistency of the stride-to-stride or step-to-step pattern) and the symmetry of gait (defined as the difference between step and stride regularity) as determined by an unbiased autocorrelation procedure that analyzed the pattern of acceleration in the vertical, mediolateral and anteroposterior directions.
Older adults with knee OA displayed significantly less step regularity in the vertical (
< 0.05) and anteroposterior (
< 0.05) directions than controls. Females with knee OA were also found to have significantly less mediolateral step regularity than female controls (
< 0.05), whereas no difference was found between males.
The results showed that the regularity of the step pattern in individuals with bilateral knee OA was less consistent compared to similarly-aged older adults with healthy knees. The findings suggest that future studies should investigate the relationship between step regularity, sex and movement direction as well as the application of these methods to the clinical assessment of knee OA.
Journal Article
Composing in and through the body
This commentary investigates role of the body in the composition, performance, and audition of the author's musical works included in the portfolio. Starting from Jean-Jacques Nattiez's model of the three-part 'total musical fact', this text describes how the compositional research both adheres to this model and attempts to transcend it through the body. It examines notational strategies that target performing or perceiving bodies, the use of physical and perceptual thresholds, the somatic experience of the composer at various stages throughout the compositional process, and the structuring of the listening environment. Human error and expressive failure are cited as means through which performing bodies forge collectivities with the audience, thereby exemplifying the queer utopian aesthetics described by José Esteban Muñoz and Judith/Jack Halberstam, especially as relates to the notion of hopeful exertion. The staging of absence is examined through various types of embodied engagements with musical material, highlighting the tendency of imminent physicality to draw perceptual focus away from material—an 'avalanche' that can all-too-easily elide the composer's 'fingerprint', in the language of Max Murray. Extended instrumental techniques, the use of electronics, and the genre of performance-installation are also discussed in terms of their relationship to the bodies of the composer, the musician, and the listener. Phenomena such as composed and field-recorded forms of metastasis and masking are addressed for their prioritization of perceptual responses in the listener above material or formal development. Given that all perceived sound is necessarily mediated through bodies (at the latest, through listeners' ears), this commentary and these compositions seek to concentrate awareness—vigilantly and in a number of specific ways—on the beauty and inherent transformative potential of this ever-present reality.
Dissertation
Multiplatform sports journalism
Once upon a time there were newspapers and periodicals, radio and newsreels and television and, in a few instances, film. Now there is multiplatform. Where does one medium stop and another start? For the young trainee journalist, is it even possible to say, \"I want to be a sports writer\"? To get on, must you just provide content? It's not a surprise. In the UK, national newspaper sales fell by 19.7 per cent between 2000 and 2009 and continue to decline. For the individual journalist, the new media landscape has created employment opportunities, new ways of sharing content with audiences, a need for new skills and the ability to work more efficiently. It has also created more work. But ask any journalist what working across multiple platforms involves and the stock answer will be: \"working harder and longer\". Tom Fordyce, co-host of That Peter Crouch Podcast, says multiplatform is both a boon and bane for sports journalists. \"It creates some great opportunities, but can also be totally relentless. There's always something happening; you feel like you should always be on your phone, and people assume you are always available.\"
Book Chapter
Routledge Handbook of Sports Journalism
The Routledge Handbook of Sports Journalism is a comprehensive and in-depth survey of the fast moving and multifaceted world of sports journalism. Encompassing historical and contemporary analysis, and case studies exploring best practice as well as cutting edge themes and issues, the book also represents an impassioned defence of the skill and art of the trained journalist in an era of unmediated digital commentary.
With contributions from leading sports media scholars and practising journalists, the book examines journalism across print, broadcast and digital media, exploring the everyday reality of working as a contemporary reporter, editor or sub-editor. It considers the organisations that shape output, from PR departments to press agencies, as well as the socio-political themes that influence both content and process, such as identity, race and gender. The book also includes interviews with, and biographies of, well-known journalists, as well as case studies looking at the way that some of the biggest names in world sport, from Lance Armstrong to Caster Semenya, have been reported.
This is essential reading for all students, researchers and professionals working in sports journalism, sports broadcasting, sports marketing and management, or the sociology or history of sport.
