Body weight support (BWS) increases lower extremity kinematic variability in elderly females, contrary to expectations for gait improvement. Further research is needed to determine if training can mitigate this effect.

Area of Science:

  • Biomechanics
  • Gerontology
  • Rehabilitation Science

Background:

  • Aging increases gait variability, contributing to falls in the elderly.
  • Body weight support (BWS) training is a potential intervention to improve elderly gait and reduce falls.
  • Baseline data on BWS effects on elderly gait variability are needed before implementing rehabilitation protocols.

Purpose of the Study:

  • To determine the effect of varying body weight support (BWS) levels on lower extremity kinematic variability in young and elderly females during walking.

Main Methods:

  • Ten young and ten elderly females walked on a treadmill under four BWS conditions (1g, 0.9g, 0.8g, 0.7g).
  • Three-dimensional kinematic data of the lower extremity were captured.
  • Linear and nonlinear measures analyzed sagittal plane angular kinematics for variability.

Main Results:

  • Elderly females exhibited significantly greater hip and knee joint variability compared to young females.
  • Increased BWS levels led to greater kinematic variability at all joints, confirmed by both linear and nonlinear analyses.

Conclusions:

  • Higher body weight support levels increase lower extremity kinematic variability.
  • BWS did not decrease gait variability in this acute study, challenging its use for this purpose.
  • Future research should investigate the long-term effects of BWS training and its potential for positive transfer to normative gait patterns.
