BACKGROUND Falls in elderly people are a major health burden, especially in the long-term care environment. Yet little objective evidence is available for how and why falls occur in this population. We aimed to provide such evidence by analysing real-life falls in long-term care captured on video. METHODS We did this observational study between April 20,(More)
A bucket-handle tear of the meniscus is a vertical or oblique tear with longitudinal extension toward the anterior horn in which the inner fragment is frequently displaced toward the intercondylar notch with resultant mechanical locking of the knee joint. A precise MR diagnosis requires identification of the centrally displaced fragment because the(More)
OBJECTIVE To compare the accuracy of perceived postural limits between older fallers with good working memory and those with poor working memory. DESIGN Cross-sectional study. SETTING Research laboratory. PARTICIPANTS Thirty-three community-dwelling older adults with a history of falls. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES We(More)
Sources of variability in measurements of intraocular pressure (IOP) by applanation tonometry were examined with a repeated 3 X 3 Latin square design that allowed independent extraction of variation attributable to nine patients, three observers and the order in which the observers performed the measurements. The observers, who were experienced, did not(More)
Meniscal fragments may be difficult to detect on magnetic resonance (MR) imaging and yet are clinically significant. This paper describes and illustrates the MR appearance of an easily overlooked meniscal fragment. Ten knees, each appearing to show an abnormally large anterior meniscal horn (8 mm or more in height) were prospectively identified on MR(More)
Falls are a major cause of injury in the elderly, and risk for falls depends on frequency of imbalance episodes. Improved techniques are required for determining how risk for imbalance during daily activities depends on behavioural (e.g., risk taking) versus neuromuscular factors. We developed a novel technique to determine whether differences exist between(More)
The goal of this study was to determine whether differences exist between young and elderly adults in cautiousness or tendency to approach imbalance during a forward reaching task. Young (n = 26) and elderly (n = 25) adults participated in trials that required them to reach forward as quickly as possible to contact a target that moved back and forth, in and(More)
BACKGROUND Falls are the number one cause of injuries in older adults, and are particularly common in long-term care (LTC). Lack of objective evidence on the mechanisms of falls in this setting is a major barrier to prevention. Video capture of real-life falls can help to address this barrier, if valid tools are available for data analysis. To address this(More)
A thermographic technique is described that uses cholesteric liquid crystals that change color in response to variations in surface temperature. The crystals are embedded in elastic flexible sheets that conform to the contours of the torso and extremities. The technique is well suited to temperature measurement of individual skin dermatomes and myotomes.(More)
