Highlights

  • A prosthetic leg imposes limitations in the ability of users to actively control their mediolateral balance during standing and walking

  • While many studies focus on sagittal plane improvements during locomotion, often by means of microprocessor controlled devices, the current study focuses on frontal plane additions

  • This study aims to validate a new prototype on mediolateral balance control, quantified by variations in GRFh and active Centre of Pressure (CoP) displacements under the prosthetic foot during walking

Summary

Introduction

A prosthetic leg imposes limitations in the ability of users to actively control their mediolateral balance during standing and walking. Prosthetic walkers compensate for this by changing certain walking parameters They tend to stand longer on their sound leg and have a wider step on the prosthetic side (Hof et al, 2007; Jaegers, Arendzen, & de Jongh, 1995). They bend their trunk towards the prosthetic side when walking (Jaegers et al, 1995). Mediolateral balance control may be improved by increasing hip strategy effectiveness. To this purpose, a new, patented prosthetic device has been developed. This paper presents the design of a study focused on validating the prototype on improvements of mediolateral balance control by comparing it to a classic prosthetic set-up
