“…The fact that a hard sole did not affect step time variability or pelvis acceleration patterns to a greater extent than the standard shoe appears to confirm that these footwear properties do not affect balance control in older people (Menant et al 2008a(Menant et al , 2009a(Menant et al , 2009b. Furthermore, in contrast with our hypotheses and previous work (Menant et al 2008a(Menant et al , 2009a(Menant et al , 2009b, we did not note any detrimental effect of the soft sole shoe or any beneficial effect of the high-collar shoe on balance in the AP and ML planes.…”

“…The standard shoe had a suede leather upper, Ethylene Vinyl Acetate (EVA) sole material of average hardness (shore A-40) and thickness (27 mm under the heel and 13 mm under the first metatarsal-phalangeal joint), a low heel collar, a square heel, and a smooth sole. The modified shoe conditions are described in detail elsewhere (Menant et al 2009b).…”

This study investigated the effects of various shoe features and surfaces on step time variability and pelvis accelerations (RMS) during walking in six younger and 22 older adults. Participants walked at a self-selected speed in five shoe conditions (standard, elevated heel, soft sole, hard sole, and high collar) on two surfaces: level and irregular. Results showed an age-related reduction in step time variability on the irregular surface and increased medio-lateral (ML) acceleration RMS in older people walking on the irregular versus the level surface. When wearing the elevated heel shoes, both young and old participants displayed significant reductions in pelvis ML accelerations, suggesting a compensatory strategy to counteract for lateral instability resulting from heel elevation. Overall, the findings demonstrate that older people are less able than younger ones to meet the stepping adaptability required for negotiating an irregular surface and, as a possible consequence, have more difficulty maintaining frontal plane stability on such a surface.

“…These novel findings suggest that future researchers should examine the abilities of high and low falls-risk older adults to rapidly terminate voluntary body movement, especially as reaction time research on fallers and nonfallers has almost exclusively focused on movement initiation tasks. Indications of slower termination responses by older adults compared with the young have been reported in the literature (Cao et al, 1998;Menant et al, 2009;Tirosh & Sparrow, 2004); however, it is presently unclear whether a reduced capacity to terminate voluntary body movement could be a causative factor in falls.…”

“…A complementary ability to rapidly terminate body movement is an essential movement skill that has received much less research attention. Given the potential importance of such rapid termination responses for avoiding falls (Cao, AshtonMiller, Schultz, & Alexander, 1998;Menant, Steele, Menz, Munro, & Lord, 2009;Tirosh & Sparrow, 2004), it was of interest in the present study to examine the abilities of young and older adults to rapidly terminate voluntary postural sway movements in response to a suddenly presented stimulus.…”

The authors examined differences between young adults (n = 25) and healthy older adults (n = 48) in reaction time and the relations between center of pressure (COP) and center of mass (COM) motions during rapid initiation and termination of voluntary postural sway. Older adults were divided into low and high falls-risk groups based on Physiological Profile Assessment scores of sensorimotor function. Low falls-risk older adults had slower reaction times during anteroposterior sway initiation and decreased COP-COM separation during anteroposterior and medialateral sway initiation and anteroposterior continuous voluntary sway compared with young adults. High falls-risk older adults had slower initiation and termination reaction times in all response directions and decreased COP-COM separation during sway initiation and continuous voluntary sway in the anteroposterior and medialateral directions compared with young adults. Compared with low falls-risk older adults, high falls-risk older adults had slower initiation and termination reaction times in all response directions and decreased COP-COM separation during medialateral continuous voluntary sway. Reaction time and COP-COM measures significantly predicted group status in discriminant models with sensitivities and specificities of 72-100%. Overall, these findings highlight important associations of age-related declines in sensorimotor function related to an increased risk of falling with slower postural reaction time and reduced postural stability.

“…Shoulder-hip ratio and hip rotation are considered important features for detecting gender based on gait [6][7][8][9]. Many features such as step length, speed and double-support time have been analyzed in the gaits of elderly [10,11]. In the medical application area, gait features usually depend on the disease that is being analyzed, for example, asymmetries in movement patterns were identified as important features in the analysis of developmental coordination disorder in children [12].…”

Although there has been much previous research on which bodily features are most important in gait analysis, the questions of which features should be extracted from gait, and why these features in particular should be extracted, have not been convincingly answered. The primary goal of the study reported here was to take an analytical approach to answering these questions, in the context of identifying the features that are most important for gait recognition and gait attractiveness evaluation. Using precise 3D gait motion data obtained from motion capture, we analyzed the relative motions from different body segments to a root marker (located on the lower back) of 30 males by the fixed root method, and compared them with the original motions without fixing root. Some particular features were obtained by principal component analysis (PCA). The left lower arm, lower legs and hips were identified as important features for gait recognition. For gait attractiveness evaluation, the lower legs were recognized as important features.
