Hi
There were few treatments mentioned in the literatures and few of the techniques are:
Physical therapies:


Biofeedback:
a method of educating your body to induce certain responses and thus control your symptoms. Requires training and practise. Good results in children.

Alexander Technique:
postural re-integration and (un)learning, with particular emphasis on relationship between head and neck. Requires training and practise.

Relaxation:
anything that helps you lower stress levels and encourage relaxation can be beneficial. This may be deep breathing, progressive muscle relaxation (as taught at ante-natal classes), yoga, meditation or just taking a few minutes to yourself

If you are still interested in this topic i can get you more details after a laborious search in literatures
Cheers!
