however, they they did not consider breathing, the stomatognathic system, limbic system, remaining spinal segments, pelvis or limbs.
Their review illustrates the importance of hierarchical factors in postural control
The visual field provides afferent feedback, which is used to maintain and correct posture.
Dysfunction in the visual field may lead to postural dysfunction and compensation.
For example, catanzwsiti et al. Found children attending a visually handicapped school had increase trunk deformity compared with children attending a public vocational school.
This could be viewed as demonstrating that poorer vision leads to poor posture.
The question is, are these postures compensation to optimise vision?
There is evidence that in some cases these compensations improve vision.
Stevens and Hertle studied children with congenital nystagmus and examined whether those with a compensatory head posture had better or worse vision.
They found that that children with a compensatory head poster had significantly improved vision compared with those who did not.
This exemplifies both how posture can be altered to enhance vision,and how some individuals will select more effective compensatory strategies than others.
Correcting visual impairments may improve posture.
Nucci and Rosenbaum looked at patient with and acquired vision loss in one eye and concomitant anomalous head posture.
They then carried out surgical intervention to enhance the patient' vision.
They made statistically significant improvement in posture in 80% of the patients treated.
So it appears that there is a strong association may be bidifrectional
