Abstract- Gait analysis
systems have been developed to provide an objective and quantitative means of
analyzing lower limb function. Visual observation has been shown to be inadequate
for the accurate assessment of gait, emphasizing the need for some form of quantitative
measurement and biomechanical analysis.
In the study of the biomechanics of the ankle joint during gait, the ankle axis
cannot be considered to be at exact right angles to the plane of progression
because of a variable degree of toe-out. Failure to correct for this degree
of toe-out could lead to significant error in the interpretation of data.
This present study set out to measure the normal degree of toe-out and to relate
it to external markers attached to the foot and ankle, as used in many gait
analysis systems.
