Conventional Gait Model

Introduction

The conventional gait model has many variations. The defacto standard is its implementation from Vicon and called Vicon Plug In Gait model (PiG).

This includes the following angles:

ANGLES POSITIVE ROTATION AXIS DIRECTION ANGLES POSITIVE ROTATION AXIS DIRECTION
LPelvisAngles 1 Anterior Tilt Prg.Fm. Y Anti-clockwise RPelvisAngles 1 Anterior Tilt Prg.Fm. Y Anti-clockwise
LPelvisAngles 2 Upward Obliquity Prg.Fm. X’ Anti-clockwise 2 Upward Obliquity Prg.Fm. X’ Clockwise
LPelvisAngles 3 Internal Rotation Prg.Fm. Z’’ Clockwise 3 Internal Rotation Prg.Fm. Z’’ Anti-clockwise
