Mechanisms of Gait Asymmetry Due to Push-Off Deficiency in Unilateral Amputees

The Relationship between Muscle Strength and Gait Asymmetry in Unilateral, Trans-tibial Amputees

INTRODUCTION Persons with unilateral, trans-tibial amputation (TTA) have an increased risk of developing osteoarthritis (OA) in the knee of their intact limb [1]. Several OA risk factors, such as peak knee external adduction moment and vertical ground reaction force load rate, have been found to be greater on the intact limb in TTAs [2]. Betweenside strength discrepancies observed in TTAs [3] m...

Effect of Asymmetric Knee Height on Gait Asymmetry for Unilateral Transfemoral Amputees

Transfemoral prostheses have traditionally sought to emulate symmetry in their designs. Using a symmetric prosthesis for a physically asymmetric unilateral transfemoral amputee typically causes asymmetric gait patterns. This research study investigates the effects of prostheses with lower knee heights than the intact knee and a pilot study of the combined effects of adding distal mass with lowe...

Gait recovery pattern of unilateral lower limb amputees during rehabilitation.

The aim of this study was to determine the rate at which gait recovery as measured by temporal distance factors (velocity and symmetry) occurs in unilateral lower limb amputees. A microcomputer foot switch system was used to record the gait patterns of twenty subjects, mean age 65.1 years. The initial measurement was taken when the subject was capable of walking 6 metres with an interim prosthe...

Adaptation to altered balance conditions in unilateral amputees due to atherosclerosis: a randomized controlled study

BACKGROUND Amputation impairs the ability to balance. We examined adaptation strategies in balance following dysvascularity-induced unilateral tibial amputation in skilled prosthetic users (SPU) and first fitted amputees (FFA) (N = 28). METHODS Excursions of center of pressure (COP) were determined during 20 s quiet standing using a stabilometry system with eyes-open on both legs or on the no...
