Effect of Diffuse Noxious Inhibitory Controls on Forward Flexion

Abstract

In this study we examined the effect and maintenance in healthy subjects of Diffuse Noxious Inhibitory Controls (DNIC) on the finger-floor distance in forward flexion. The subjects were 40 healthy persons who were separated into a control group and a DNIC treatment group. The finger-floor distance was measured, before, after and 30 min after DNIC treatment. Significant differences were found for all combinations by analysis of variance and Bonferroni multiple comparison in the treatment group. By performing DNIC, the finger-floor distance became greater and the effect lasted for 30 min. However, at 30 min, the effect had declined compared to that immediately after DNIC. DNIC increased the finger-floor distance and although the effect showed a tendency to decline it was effective for at least 30 min.
