hi friends
cervical rib as such may not cause any symptoms.mostly it is diagnosed while doing some routine check up.symtoms arises when the cervical rib or associated anomalous bands cause compression of lower cervical nerve roots.if its causes irritation of the nerve roots and lower its threshold to mechanical stimulation,it results in cervicobrachial pain syndrome.then the treatment programme should should be the one for mechanosensitivity described by elvey and hall.later our treatment programme should include shoulder girdle elevation exercise,scapular muscle stabilization exercise
