I want to examine the efficacy of a lower limb stretching program on foot alignment or posture.
I recommend Clarke's angle as quick, simple, reliable and valid method of evaluation for static foot posture according to literature review
Hi,
A good outcome for you could be the Foot Posture Index. You can find how to do and more specific information in the paper below
Redmond AC, Crosbie J, Ouvrier RA: Development and validation of a novel rating system for scoring standing foot posture: the Foot Posture Index. Clin Biomech. 2006, 21: 89-98. doi: 10.1016/j.clinbiomech.2005.08.002.
It is a quite complete tool, also easy to perform.
Good luck!!!
Danilo
Thank you so much for all your valuable contributions. Please apart from foot posture index, is there other simple and reliable method that doesn't require a footprint. or podograph ?. i was thinking of the Navicular drop test. Thank you.
This may be of interest to you. Prediction of postural sway velocity by foot posture index, foot size and plantar pressure values in unilateral stance.

You can use navicular drop or normalized truncated navicular height also according to your sample population

There are many suggested tests of foot posture/morphology. What is perhaps more relevant is the comparison of the weight bearing and non-weight bearing morphology and the difference in arch height. You can place a mark on the skin at the measured centre of the arch (which is measurable) or the apex (which is more subjective). Measure the distance d from the mark to the floor when they person is sitting with the feet resting on the floor and then again when standing. Calculate the difference.
The non-weight bearing posture reflects the anatomy of the foot and the weight bearing posture reflects functional influences. Changes in the function of the muscles should have an effect on this arch height differential.
As far as I know this test provides reliability because the measured arch centre is objective and the difference in arch heights is not dependent on the placement of the skin marking.
