Impaired standing balance has a detrimental effect on a person's functional ability and increases their risk of falling. There is currently no validated system which can precisely quantify center of pressure (COP), an important component of standing balance, while being inexpensive, portable and widely available. The Wii Balance Board (WBB) fits these(More)
Clinically feasible methods of assessing postural control such as timed standing balance and functional reach tests provide important information, however, they cannot accurately quantify specific postural control mechanisms. The Microsoft Kinect™ system provides real-time anatomical landmark position data in three dimensions (3D), and given that it is(More)
To identify prevalence of testicular microlithiasis on ultrasound in a referred population and risk of concurrent and interval testicular tumor development. Retrospective review of our radiology database revealed 4363 scrotal ultrasounds were performed over a six-year period. Ultrasound findings were correlated with our hospital pathological database. The(More)
The aim of this research was to assess the effect of a single set of contrast preloading on peak vertical displacement (PD) during a loaded countermovement jump (LCMJ) training session. Nine strength-trained males participated in 2 randomly assigned, crossover design testing sessions consisting of 5 sets of 6 repetitions of 20-kg LCMJs with 3-minute rest(More)
The purpose of this study was to elucidate the effect of normal fluctuating [non-monophasic oral contraceptive pill (MOCP) users] and low, consistent (MOCP users) endogenous plasma estrogen levels on the strain behavior of the Achilles tendon in vivo. Twenty women (age 28.0 +/- 4.2 yr, height 1.67 +/- 0.07 m, mass 61.6 +/- 6.8 kg) who had been using the(More)

INTRODUCTION Hamstring injuries are one of the most common injuries associated with sports participation. The aim of this review is to outline identified risk factors and examine preventative strategies for reducing the occurrence of this form of injury. METHODS An electronic search of Medline and SCOPUS was carried out for key words related to the area.(More)
OBJECTIVES Physical activity has been infrequently measured objectively in non-small cell lung cancer (NSCLC). We aimed to investigate levels of physical activity, functional and patient reported outcomes at diagnosis and over six months in participants with recently diagnosed NSCLC and compare results with both physical activity guidelines and outcomes of(More)
This study investigated the hypothesis that a hearing 'map' of our surroundings is used to maintain balance control. We investigated the effects of sound on postural sway using centre of pressure analysis in 50 subjects with normal hearing, 28 with hearing loss and 19 with vestibular dysfunction. The acoustic environments utilized sound cues that were(More)
BACKGROUND Impaired postural stability places individuals with Parkinson's at an increased risk for falls. Given the high incidence of fall-related injuries within this population, ongoing assessment of postural stability is important. OBJECTIVE To evaluate the validity of the Nintendo Wii(®) balance board as a measurement tool for the assessment of(More)
OBJECTIVE To evaluate, in a community hip osteoarthritis sample, the cross-sectional associations of isometric strength and steadiness of the knee extensors and their interaction with physical performance measures of physical function. DESIGN Cross-sectional. SETTING Human movement laboratory of a university. PARTICIPANTS Sixty-seven adults (27 men(More)
