A study of visual evoked potentials and effect of relaxation technique in patients with migraine

Dalia A. Biswas, Meghana A. Gaikwad


It is a cross-sectional comparative study in which comparison was done between 1) group A comprising  of 15 cases of migraine (without aura) on medication only, 2) group B comprising of 15 cases of migraine (without aura) and practicing Rajyoga meditation and deep breathing and 3) control group who were 15 age matched normal subjects.  This study was conducted in the interictal period. The most striking finding was - A decrease in P100 (ms) at post-test in both the eyes in group B, (though this finding is not significant), in contrast to group A which showed a significant increase in P100 (ms) at post-test. Both the groups showed an increase in P100-N75 (µv) & this finding was not significant in both. Multiple comparisons using Tukey test and one way ANOVA showed significant finding between groups and within groups for P100 and N145 latencies for the right eye. No such difference was seen with left eye. We conclude that Rajyoga meditation and deep breathing can be used as adjuncts to routine antimigraine therapy. We advocate the continuous practice of these interventions which might decrease the frequency of attacks & finally the elimination of this problem.
