How useful is satellite positioning system (GPS) to track gait parameters? A review

Philippe Terrier, Yves Schutz Journal of NeuroEngineering and Rehabilitation 2005, 2:28 (2 September 2005)

GPS may provide an alternative tool to monitor walking. This paper describes how GPS can be utilized to assess basic gait parameters over an extended period of time.

Shedding light on walking in the dark: the effects of reduced lighting on the gait of older adults with a higher-level gait disorder and controls

Anat Kesler, Gregory Leibovich, Talia Herman, Leor Gruendlinger, Nir Giladi, Jeffrey M Hausdorff Journal of NeuroEngineering and Rehabilitation 2005, 2:27 (28 August 2005)

The effects of reduced lighting on the gait of older adults with a high level gait disorder (HLGD) are contrasted with the response of healthy controls. These patients become more unsteady when they walk in near darkness, despite adapting a slow and cautious gait.

Stride-to-stride variability while backward counting among healthy young adults

Olivier Beauchet, Véronique Dubost, François R Herrmann, Reto W Kressig Journal of NeuroEngineering and Rehabilitation 2005, 2:26 (11 August 2005)

The effects of a simple dual tasking task on stride velocity and stride-to-stride variability of stride time and stride velocity variability.

Attention demanding tasks during treadmill walking reduce step width variability in young adults

Mark D Grabiner, Karen L Troy Journal of NeuroEngineering and Rehabilitation 2005, 2:25 (8 August 2005)

When young adults walked on a motorized treadmill while performing the Stroop test, step width variability is significantly decreased, suggesting a voluntary adaptation of a more conservative gait.

Fractional Langevin model of gait variability

Bruce J West, Miroslaw Latka Journal of NeuroEngineering and Rehabilitation 2005, 2:24 (2 August 2005)

Abstract | Full text | PDF | PubMed | Editor’s summary

A fractional Langevin equation is constructed to model the underlying motor control system. The results provide evidence for the weakly multifractal nature of gait.

Effect of gait speed on gait rhythmicity in Parkinson's disease: variability of stride time and swing time respond differently

Silvi Frenkel-Toledo, Nir Giladi, Chava Peretz, Talia Herman, Leor Gruendlinger, Jeffrey M Hausdorff Journal of NeuroEngineering and Rehabilitation 2005, 2:23 (31 July 2005)

Abstract | Full text | PDF | PubMed | Editor’s summary

The relationship between walking speed and gait variability measured in PD patients compared to healthy controls is examined. The results suggest that swing time variability does not depend on gait speed.

Managing variability in the summary and comparison of gait data

Tom Chau, Scott Young, Sue Redekop Journal of NeuroEngineering and Rehabilitation 2005, 2:22 (29 July 2005)

Heuristic guidelines for the summary of gait variables and the comparison of gait curves including some practical solutions to a number of commonly encountered analytical challenges in dealing with gait variability.

Too much or too little step width variability is associated with a fall history in older persons who walk at or near normal gait speed

Jennifer S Brach, Jaime E Berlin, Jessie M VanSwearingen, Anne B Newman, Stephanie A Studenski Journal of NeuroEngineering and Rehabilitation 2005, 2:21 (26 July 2005)

The linear and nonlinear associations between gait variability and fall history are examined in a large retrospective study.

Gait dynamics in mouse models of Parkinson's disease and Huntington's disease

Ivo Amende, Ajit Kale, Scott McCue, Scott Glazier, James P Morgan, Thomas G Hampton Journal of NeuroEngineering and Rehabilitation 2005, 2:20 (25 July 2005)

Quantification of temporal and spatial indices of gait dynamics in a mouse model of PD and a mouse model of HD demonstrate distinct characteristics of gait and gait variability in these animal models.

Gait variability: methods, modeling and meaning

Jeffrey M Hausdorff Journal of NeuroEngineering and Rehabilitation 2005, 2:19 (20 July 2005)

A commentary introducing nine reports on the results of recent investigations into gait variability, the stride-to-stride fluctuations in walking.
