Study Summary
The biomechanics of changing direction while walking has been largely neglected despite its relevancy to functional mobility. In addition, an increased risk of injury can be associated with turning due to a decrease in stability. The objective of this study is to understand the biomechanics of turning gait in sample populations of intact and trans-tibial amputees and the capacity of prosthetic components to facilitate transverse plane movement. The clinical impact of this investigation is the development of interventions that increase functional mobility, stability and safety while turning. The researchers propose to investigate three sets of hypotheses. The first set addresses the fundamental biomechanical mechanisms associated with walking along a circular trajectory, how intact subjects differ from amputees, and the effect of a rotation adaptor pylon. The second set of hypotheses addresses dynamic stability and the potential influence of prosthetic interventions. The third set of hypotheses addresses how the rotational properties of the prosthetic pylon can influence comfort and mobility during daily activities.
Primary Outcome
Maximum finite-time Lyapunov exponents were used to estimate the local dynamic stability of the amputee's sagittal plane hip, knee and ankle angles for their prosthetic limb with and without the torsion adapter while walking straight, while turning with the prosthesis on the inside of the turn, and while turning with the prosthesis on the outside of the turn. Maximum finite-time Lyapunov exponents measure the rate of kinematic separation of a gait cycle trajectory perturbed by naturally occurrin
Interventions
- DEVICE Transverse plane rotation adaptor pylon
