Support Vector Machines (SVMs) Based Framework for Classification of Fallers and Non-Fallers
… cause of mortality among older adults, and non-fatal falls result in reduced function and poor quality of life for older adults. Although much is known about the mechanisms and contributing risk factors relevant to falls, falls still remain a significant problem associated with this age …

Is Allocation of Attention Impaired in Fallers Compared to Non-Fallers? An Event-Related Potential Study
… exaggerated in the faller group compared to the non-faller group when cognitively processing the visual target stimuli. This suggests differences in the way stimuli are cognitively processed and classified between fallers and non-fallers. Keywords: falls, attention, allocation, risk, EEG, ERP, …

Effect of Textured Insoles on Gait Variability During Continous Overground Walking in Older Adult Fallers and Non-Fallers
… continuous overground walking in older adult fallers and to compare these results to a healthy group of older adult non-fallers. Group differences were found with respect to mean step- and stride time. No significant differences were found for step- and stride time variability along with the …

Comparison of Elderly Non-Fallers and Fallers on Performance Measures of Functional Reach, Sensory Organizations, and Limits of Stability
… The purpose of this study was to compare elderly non-fallers and fallers for differences in the following: (1) mean functional reach (FR), (2) mean anterior limits of stability (LOS), (3) mean posterior LOS, and (4) mean sensory organization test (SOT) composite score. The following correlations …

Biomechanical and psychological factors that distinguish fallers from non-fallers : a comparative study of transtibial amputees and able bodied individuals
… falling. While biomechanical differences between fallers and non-fallers have been identified in older adults, no research to date has specifically compared amputee fallers and non-fallers. The aim of this thesis was to undertake a biomechanical comparison of amputee and able-bodied fallers and …

Using fractal dimension analysis to improve clinical balance and mobility assessments for discriminating fallers from non-fallers : a cross-sectional analysis
… identify those characteristics associated with fallers. Non-traditional analysis techniques such as the fractaI dimension (FD) arc less well accepted. Therefore, statistical models to discriminate fallers and non-fallers utilising both traditional and non-traditional melhods should be …

Falling Head Over Heels: Investigating the higher-level cognitive and electrophysiological processes underlying gait control and falls in older adults and stroke survivors
… potentials in healthy young and older adult “fallers” and “non-fallers”, and also in a sample of stroke survivors. The results suggest that executive top-down processes (working memory in particular), play a role in gait control during dual-task walking generally, and that executive processes …

Social Marketing and Falls Prevention: Market Segmentation and Product Positioning
… into frequent falling males and females, and non-falling males and females. Frequent fallers were defined by having experienced 2 or more falls in the past year, where non-fallers had experienced 1 or less falls. Twelve focus groups were conducted with thirty-five participants (N=35), 65 years …

The Lifestyle-integrated Functional Exercise Program for Older Adults
… falls are the most common cause of fatal and non-fatal injuries among older adults over the age of 65 (Centers for Disease Control and Prevention [CDC], 2009). Falls can lead to a myriad of traumatic physical and emotional consequences. Integrated exercise programs such as the …

Evaluating Alternative Inertial Measurement Unit Locations on the Body for Slip Recovery Measures
… have been shown to increase significantly among fallers as compared to non-fallers. Often, slipping kinematics are measured using optoelectronic motion capture (OMC), requiring a laboratory setting and limiting data collection to experimentally-controlled conditions. Inertial measurement units …

Gait variability in persons with multiple sclerosis
… by a novel metric, separates recurrent and non fallers with MS. Additional research into gait variability in MS is warranted to further evaluate differences between MS and controls as well as to investigate underlying factors that may drive gait variability in MS.

Predictor Variables Related To Falls In A Long-Term Care Environment
… be statistically significant between groups of fallers and non-fallers. In this setting, the current design of the tool had limited accuracy and exhibited an inability to effectively discriminate between resident populations at risk of falling and those not at risk of falling. Consequently, the …

Quantifying gait stability based on body segment coordination relationships measured with wireless sensors
… of overground walking needed to separate MS fallers from MS non-fallers were determined using data collected continuous 4-minutes of walking over a 10-meter walkway in the laboratory. RELEVANCE: Falls are a leading cause of non-fatal injury and a significant health problem for persons with …

Whole body coordination during turning while walking in stroke survivors
… pattern were similar to healthy controls and non-fallers. Therefore, incidences of falls during turning following stroke may not be due to impaired movement patterns alone. On this basis, we suggest that rehabilitation efforts and further studies should address the interplay of impaired …

Fall Risk Assessment By Measuring Determinants Of Gait
… appeared to be capable of differentiating fallers and non-fallers within older adults, as well as differentiating normal walking conditions and constrained walking conditions. Furthermore, this study also leveraged portable wireless sensor techniques and investigated if miniature inertial …

Deficits in inhibitory function mediate age-related multisensory and postural function decline
… compared between young adults (YA), older non-fallers (NF) and older adults with a fall history (FH) to examine effects of natural aging and surplus consequences that may contribute to an individual's risk of falling. Overall, we found that natural aging does in fact result in reduced …

Quantification of the human postural control system to perturbations
… able to successfully differentiate recurrent fallers from non-fallers, while only five out of 30 more common descriptive and stochastic COP measures could distinguish the two groups. Fall history and the IDA parameter of entropy were found to be significant risk factors for falls. This …

On Falls in the Elderly –Epidemiological Studies from the Longitudinal General Population Study ‘Good Aging in Skåne’ (GÅS), Sweden
… that there was an overrepresentation of fallers in a distinct subgroup of the oldest-old, and a frail group with multiple risk factors. The risk of falling appeared to increase in a non-linear, almost exponential way with increasing number of risk factors. Paper II used data from the …

Patterns and predictors of falls and their consequences in extreme old age
… high levels of injuries (38% of falls but 68% of fallers) including fractures – one man and 1 in 8 of the women who fell. One in three people had at least one hospital admission, 2/3 of them at least partly due to falling, 2/3 of these directly prompted by a fall. Mean total length of stay of …

Toward understanding factors affecting falls among individuals who are obese
… extremity muscle strength, and body size between fallers and non-fallers, and the strength of the association between the same factors and slip severity. Participants' gait, plantar sensitivity, executive function, lower extremity muscle strength, and body size measures were obtained. An …
