Correlation among smartphone addiction, craniovertebral angle, scapular dyskinesis, and selected anthropometric variables in physiotherapy undergraduates

OBJECTIVES: Smartphone addiction has been indicated to reduce the craniovertebral angle, thereby causing a forward head posture and increasing scapular dyskinesis. This study determined the correlation among smartphone addiction level, craniovertebral angle, scapular dyskinesis, and selected anthropometric variables in physiotherapy undergraduates. METHODS: Seventy-seven participants were recruited from the Department of Physiotherapy, College of Medicine, University of Lagos, through a purposive sampling technique. The smartphone addiction level was assessed with the short version Smartphone Addiction Scale (English version). Craniovertebral and scapular dyskinesis were assessed using the photographic method. Descriptive and inferential statistics were used to analyse the data at an alpha level of 0.05. RESULTS: The analysis in this study revealed that many undergraduates are addicted to using smartphones. There was no significant difference in the addiction level (p = 0.367) and in scapular dyskinesis (p = 0.129) between male and female participants. However, there was a significant difference in craniovertebral angle (p = 0.032) between male and female participants. There was a significant relationship among smartphone addiction, craniovertebral angle (r = 0.306, p = 0.007), and scapular dyskinesis (r = 0.363, p = 0.007) in male and female participants. CONCLUSION: A high level of smartphone addiction reduces the craniovertebral angle and increases scapular dyskinesis. Therefore, the smartphone addiction level should be assessed in all patients with neck and shoulder pain to plan appropriate management.
