[The biomechanical pathogenesis and differentiated therapy of cervical headache (author's transl)].

Dysfunction in the upper region of the cervical vertebral column is largely to be regarded as the primary disorder from which secondary anatomical substrates, especially degenerative manifestations, develop. We must shift our attention from pathomorphology to function. There are two main types of disordered vertebral function which may lead to headache in many cases: 1. hypomobility (blocking) 2. hypermobility. Suggestions are made for selective methods of examination which help the detection of disturbed function. Cinematography can be used for substantiation. Diagnostic differentiation indicates possibilities for special manipulative, physical, surgical and orthopedic treatment.
