Research: the effect of an osteopathic treatment on rein tension during training.

During the study, the rein tension of all participating horses was measured. Half of the research group received treatment for mobility restrictions between the poll and the upper neck (occipito-atlanto-axial joint). After treating half of the research group, the rein tension of the entire group was measured again. The result showed that the treatment of the occipito-atlanto-axial joint in this study appeared to have more of an effect on reducing the average rein tension than on decreasing the difference in rein tension.
