Effect of the AST Chiro method on visual acuity

To investigate the effect of the AST Chiro treatment on visual acuity, 50 subjects were carried out by the AST Chiro method and visual improvement was evaluated. Marked visual improvement was observed in over 80% of these subjects treated and the precise proceedings were reported here. Subjects younger than 20 years old were progressively treated than those of other age groups. Although in some cases, there was observed no distinct effect, a great number of subjects achieved marked visual improvement. These results suggest that the AST Chiro method would be an effective therapeutic means to improve the visual acuity.
