Abstract

Background: Musculoskeletal impairments that are associated with posture attitude and duration of smartphone usage are an important growing public health conditions especially among university students. The relation between addictive smartphone and headache episodes is established, however, there is a debate in literature about cervical alignment among addictive smartphone users with cervicogenic headache (CGH). Purpose: investigate craniovertebral angle (CVA) between addictive smartphone with CGH and non-addictive without CGH and evaluate the correlation between CVA with clinical headache characteristics. Methods: In this matched case control, forty physical therapy university students were assigned into two groups, addictive smartphone with CGH and non-addictive smartphone without CGH. A smartphone addictive scale was used to differentiate between both groups, CGH was diagnosed based on International Headache Society criteria with VAS to assess headache intensity and CVA which determine cervical posture was measured through AI Posture Evaluation and Correction System applications. Results: Unpaired t-test shows a significant difference in CVA (p<0.012) with a large effect size (0.83) between addictive smartphone users with CGH when compared to their matched control. Spearman’s correlation coefficient reveals no significant correlations between CVA (p > 0.767) with any headache characteristics (intensity, duration and frequency). Conclusion: However, no significant correlation between CVA and any clinical headache characteristics, CVA shows statistically significant with a potential clinically meaningful decrease in addictive smartphone with CGH when compared to their matched control. The clinicians should examine cervical posture and time spent smartphone as important factors in management of CGH
