Impairment of intrinsics is associated with what symptoms?
cervical spine pain and cervicogenic headaches
Often seen in older patients, excessive translation is associated with …?
loss of intrinsic muscle function, bony changes (bone spurs)
Cervical extrinsic muscles produce force with ____ and cause _____ translation of vertebrae with flexion
flexion; forward translation
A patient comes in with tight upper Trapezius and levator scapulus, inhibited Rhomboids and serratus anterior, inhibited neck flexors, and tight pectoralis, what do you think he has?
Upper Crossed Syndrome/ Vladimir Janda
If your deep neck flextures don’t work, it can cause stress on your spine, which causes forward translation.. this leads to abnormal bone processes. Then Stretch of the OA?
…
Cervogenic Headache is caused by what?
Hypertonic or shortened muscles of intrinsic ce
