Effect of C2 snAG and Reverse snAG in Cervicogenic Headache using Headache Disability Index

To find the effect of C2 SNAG and Reverse SNAG in age group of 18–29 years and to compare C2 SNAG and Reverse SNAG in cervicogenic headache using headache disability index

Design-Randomised, controlled trial. Participants-45 subjects diagnosed with cervicogenic headache. intervention-Group A received C2 SNAG and conventional treatment, group B Reverse SNAG and conventional treatment and group C conventional treatment, for 7 consecutive days. Outcome measures were Headache disability index, and Numerical Pain Rating Scale, assessed and documented pre and post treatment.

Pre-post analysis of HDI values of group A and group B was decreased to 42 (95% CI 33.79 to 50.21) and 52 (95% CI 41to 63) respectively, and NPRS values was reduced to 3.4 (95%CI 2.42 to 4.38) and 4.6 (95%CI 3.18 to 6.02) respectively. Between the group analysis of HDI by Dunn's multiple comparisons test showed no significant difference (p>0.05) between all three groups. Between the group analysis of NPRS by Dunn's multiple comparisons test showed significant difference (p<0.01) only between group A and C.

C2 SNAG and Reverse SNAG technique were effective in reducing functional disability and headache intensity. Also C2 SNAG was found to be more effective in reducing headache intensity when compared with other group.
