hi.

Hi Maryam,

I will do my best to answer this one. There are many papers regarding the role of strengthening for neck pain, postural correction, and motor control. If you are looking for articles on the role of specific muscles, I suggest the fine review by Schomacher and Falla:

 http://dx.doi.org.une.idm.oclc.org/10.1016/j.math.2013.05.009 

I believe you will find the references of this article to be an excellent resource as well. 

However, as to how isotonics impact the disc, it is a complicated interplay between the finite elements and the neuromuscular system. I suggest Panjabi as a good reference to explain the interplay of the systems. While there is no exercise to "strengthen" the annulus, as it is non-contractile tissue, strengthening may alter postural alignments thereby changing the relative stress on the disc,  or alter abnormal stresses such as shear on the disc via adaptations in control. 

Hope this helps...

Best regards,

Brian

Thanks Brian for your help.

May you please send me the title of the article by Schomacher and Falla and the one by Panjabi?
