Read an interesting column on how nobodies really walks correctly for a good spine and back, found it very interesting,, try it out...
1.) walk on your heels first
2.) chest pivoted out slightly to create a curve as you work on your heels
3.) hold head high as if touching the ceiling, neck straight head up, looking forward.
I feel this stretches the back up, creates the correct curve of the spine and you feel a foot bigger and helps posture.
If you look at other people in the street walking, 80% of them are misaligned.

I believe Autism may be a gyro-balance disorder, hence the cognitive brain is needed to keep up the neck, I still suffer from lagging of the neck whilst sleeping. It has been noticed that an early signal of autism is neck lagging(head falls to the side and needs to be held up by the parent). The brain keeps up the head/neck, not the body. The university of Israel found that bi-polar is also an body/brain imbalancing disorder. DANCE, movement and central balancing, ie. Tai CHi has been found to help autistic people. Dizziness, vertigo, gravity displacment(up or down) have always affected me.
