Introduction: Dysfunction of cephalic joints and its options of treatment are the subject of this thesis. Three different treatment technics are introduced: trigger point therapy, Muscle-Energy-Technic (MET), and the manipulation.
Question: “Does a dysfunction of the cephalic joints and its treatment affect the visual acuity?” If a dysfunction of the cephalic joints interferes with the eye-sight, the treatment of the cephalic joints may have an effect on the visual acuity.
Objective of the Thesis: Extensive literary research, material, and the collected data gathered in expert interviews are provided to show the coherence of a dysfunction or respectively the treatment of the cervical joints with the visual acuity. The results of this study can be subject to further empirical studies related to the respective treatment technics presented in this thesis.
Methodology of the Thesis: Literary research was conducted via PubMed, Google Scholar and the library of the medical faculty of the “Westfälische Wilhelms-Universität Münster”. Four experts were interviewed on the subject. The interpretation of the data was accomplished by a qualitative summarizing analysis of content after Philip Mayring and supported by MAXQDA, a software especially developed for this kind of research methods.
Results: A dysfunction of the cervical joints primarily affects the visual acuity via the sympathetic afferents. A specific effect on the visual acuity subsequent to medical treatment of the cervical joints could not be definitely proved by literary research and expert interviews. Although a coherence can be assumed it still has to be confirmed by further
representative and empirical studies.
