The so called "Wikipedia reference-linkfrozen shoulder" problem used to confuse and worry me also, till about twenty years ago when I began to treat the cervical spine instead of the shoulder . The method i now call Continuous Mobilisation , when applied to the lower cervical Wikipedia reference-linkfacet joints , will release those joints from their protective tone . When this occurs ( within one to three minutes in most cases for each joint ) it will be noted that referred pain and a pattern of altered recruitment within the specific myotome of that joint/nerve , will be affected . Immediate and lasting resolution of the symptoms of this shoulder pain problem are resolved . If severe , this may take up to three treatments. I have not come across a frozen shoulder /Wikipedia reference-linkadhesive capsulitis/"impingement" problem that has not had a significant ( and usually 100% ) contribution from spinal joints/nerves since the late eighties.
The alert therapist will immediately note , with carefull examination, that the facet joints C456 on the side of the complained of shoulder , will invariably be tender to deep palpation and attempts at passive movements unilateraly. Further information on the CM method can be posted if any wish to explore this method further. This problem ( and many like it ) are no longer the mystery once thought of , though the information about this minor revolution ( for some at least ) appears not to have filtered through in many quarters. Treatments of the shoulder are a waste of time , cruel and produce poor results at best. CM to the cervical spine however , done with skill and persistance , will permanently resolve this problem in a short time .
