Falls in older adults are a major health and societal problem. It is thus imperative to develop highly effective training paradigms to reduce the likelihood of falls. Perturbation training is one such emerging paradigm known to induce shorter term fall reduction in healthy young as well as older adults. Its longer term benefits are not fully understood,(More)
BACKGROUND Previous studies indicated that a single session of repeated-slip exposure can reduce over 40% of laboratory-induced falls among older adults. The purpose of this study was to determine to what degree such perturbation training translated to the reduction of older adults' annual falls risk in their everyday living. METHODS Two hundred and(More)
Falls frequently cause injury-related hospitalization or death among older adults. This article reviews a new conceptual framework on dynamic stability and weight support in reducing the risk for falls resulting from a forward slip, based on the principles of motor control and learning, in the context of adaptation and longer-term retention induced by(More)
The purpose of this study was to determine whether stability and limb support play a similar role in governing slip outcome in gait-slip as in sit-to-stand-slip, and whether such prediction could also be derived based on measures of these variables during regular, unperturbed movements. Fifty-three and forty-one young subjects all took one recovery step(More)
OBJECTIVE To determine whether aging diminishes one's ability to rapidly learn to resist falls on repeated-slip exposure across different activities of daily living. DESIGN Quasi-experimental controlled trial. SETTING Two university-based research laboratories. PARTICIPANTS Young (n=35) and older (n=38) adults underwent slips during walking. Young(More)
OBJECTIVES To determine whether the fall-resisting skills acquired from a single perturbation training session can be retained for 6 months or enhanced by an intermediate ancillary session. DESIGN A randomized controlled trial. SETTING Biomechanics research laboratory. PARTICIPANTS Community-dwelling elderly (N=48; age, >65 y). INTERVENTIONS Initial(More)
A person's awareness of potential slippery walking conditions induces a cautious gait pattern. The purposes of this study were to determine whether neuromechanical changes associated with such cognitive conditioning are sufficient to alter the outcome of a slip and whether the effects of such conditioning are comparable to those of motor training. Prior to(More)
A vital functional plasticity of humans is their ability to adapt to threats to posture stability. The purpose of this study was to investigate adaptation to repeated trips in walking. Sixteen young adults were recruited and exposed to the sudden (electronic-mechanical) release of an obstacle, 11-cm in height, in the path of over ground walking during the(More)
OBJECTIVE We aimed to determine the effect of distinctly different cognitive tasks and walking speed on cognitive-motor interference of dual-task walking. METHODS Fifteen healthy adults performed four cognitive tasks: visuomotor reaction time (VMRT) task, word list generation (WLG) task, serial subtraction (SS) task, and the Stroop (STR) task while(More)
OBJECTIVE To examine the effects of session intensity (number of slip exposures) and frequency on the retention of acquired adaptation for prevention of backward balance loss after repeated-slip training. DESIGN A 4-group, randomized, and controlled study. SETTING Biomechanics research laboratory. PARTICIPANTS Healthy young subjects (N=46; 21 men). (More)
