A Study of the Impact of Head Position on Foot Pressure in Stance
A study testing Foot pressure measurement in people with Study the Impact of Head Position, run by University Hospital, Strasbourg, France.
Trial summary
When examining a subject in quiet stance from the side, the leg segment is usually seen to be oriented upwards and forwards by about 5°; the knee may be flexed by a few degrees, the shoulders are behind the great trochanter and the head is held forwards. Read more about this study

About this study
Official title: A Study of the Impact of Head Position on Foot Pressure in Stance.
When examining a subject in quiet stance from the side, the leg segment is usually seen to be oriented upwards and forwards by about 5°; the knee may be flexed by a few degrees, the shoulders are behind the great trochanter and the head is held forwards. The forward head position moves the center of gravity forwards and thus may increase pressure under the forefoot. Conversely, moving the head backwards should be accompanied by an increase in pressure under the heel and thus decreased pressure under the forefoot.
The study's objective is to study the influence of alignment of the head with the back (i.e. a rearward head position) and head rotation on the foot pressure distribution (measured using a foot pressure platform).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Foot pressure measurementOther
Description of the foot pressure measurement:
The subject stands on the platform, with the heels and buttocks touching a vertical plane and the head held freely. The subject then moves his/her head backwards so that it touches the vertical plane. Next, he/she turns the head to the right and then towards the left. Each of these positions is maintained for 2 minutes.
The platform's sensors measure the anteroposterior foot pressure distribution during the various acquisitions.
