Craniocervical flexion performance in computer users: An observational study

Study aim: To compare the performance of deep cervical flexors (DCF) among computer users (CU) and non-users using the craniocervical flexion test (CCFT). Material and methods: Eighty nine computer users and 100 non-users were recruited for evaluation of their craniocervical muscle performance. The activation score and performance index were assessed using the CCFT. Comparison of craniocervical flexor performance between the two groups was evaluated using the Mann Whitney test. A Chi-Square test was used to test the association between age, years of work and craniocervical flexion. Significance was set at p ≤ 0.05. Results: The median activation score was lower among computer users (median pressure-24 mmHg as compared to non-users (median pressure-28 mmHg) (p < 0.01). The performance index among computer users was lower when compared to nonusers. Also, age (p < 0.001) and the years of work experience (p = 0.006) were associated with the DCF performance. Conclusion: CU have lower activation and endurance of the DCF compared to non-users. The endurance of the DCF was associated with the age and years of computer usage.
