Neck Strength in Coronal and Sagittal Head Movement in Military Pilots and Aircrew With Chronic Neck Pain: A Systematic Review With Meta-Analysis

Published:November 03, 2022DOI:https://doi.org/10.1016/j.jmpt.2022.09.006

      Abstract

      Objective

      This systematic review aimed to assess whether there is a difference in neck strength between military pilots and aircrew with and without chronic neck pain.

      Methods

      The PubMed, Embase, and Scopus databases were searched. Two independent reviewers selected relevant full articles comparing neck strength between military pilots and aircrew with and without chronic neck pain. Two independent reviewers extracted the data from the full articles selected. A meta-analysis was used to assess standardized mean differences in neck strength based on a random-effects model.

      Results

      The search returned 3554 results; 5 articles were included in the study. Military pilots and aircrew with chronic neck pain showed no difference in neck strength from military pilots and aircrew without chronic neck pain for flexion and extension, but did show a neck strength reduction for right and left lateral flexion -0.29 (95% confidence interval, -0.52 to -0.06; I² = 3%) and -0.23 (95% confidence interval, -0.45 to 0.00; I² = 0%), respectively.

      Conclusion

      Based on this meta-analysis with a 3a level of evidence, military pilots and aircrew with chronic neck pain have reduced neck strength for coronal head movement, but not sagittal movement compared with military pilots and aircrew without chronic neck pain.
