  • Research on cervical spine function, core stability and strength of fighter pilots

    ObjectiveTo understand the cervical spine function, core stability and strength of fighter pilots, and to explore the difference of that between fighter pilots with and without neck pain.MethodsFrom October to December 2020, a double-blind design was used to test the cervical spine function, core stability and strength of fighter pilots of a certain part of the Air Force. At the same time, the area of deep cervical flexor and the thickness of transverse abdominis and multifidus muscles were measured. According to the presence or absence of neck pain in the last 3 months, they were divided into neck pain group and non-neck pain group. The cervical spine function, core stability and core strength, deep cervical flexor and transversus abdominis endurance of the two groups were compared and analyzed.ResultsA total of 38 pilots were included. There was no significant difference in age, body mass index, service life, flight time, total flight time and weekly flight time between the neck pain group and the non-neck pain group (P>0.05). There was no significant difference in cervical spine mobility between the two groups of pilots (P>0.05). The cervical flexor muscle strength [(15.5±4.9) vs. (12.1±3.0) N] and the ratio of cervical flexion/neck extension (0.6±0.1 vs. 0.5±0.1) in the non-neck pain group were higher than in the neck pain group (P<0.05). There was no significant difference in the muscle strength of other superficial cervical muscles between the two groups (P>0.05). The average value of deep neck flexor endurance in the neck pain group [25.36 mm Hg(1 mm Hg=0.133 kPa)] better than the non-neck pain group group (17.11 mm Hg) (P=0.026). There was no significant difference in test values of transverse abdominis endurance between the two groups (P>0.05). The left hip internal rotator strength [(11.9±2.6) vs. (10.0±2.1) N] and the left hip external rotator strength [(13.7±2.2) vs. (11.9±2.0) N] in the non-neck pain group were higher than in the neck pain group (P<0.05). There was no significant difference in the muscle strength of the other hip joint muscles between the two groups (P>0.05). The thickness of the right transversus abdominis in the neck pain group [(1.1±0.3) vs. (0.8±0.3) cm] was higher than that in the non-neck pain group (P<0.05). There was no significant difference in the thickness of the left transversus abdominis, the cross-sectional area of deep cervical flexor muscle and the thickness of lumbar multifidus muscle between the two groups (P>0.05).ConclusionsFighter pilots with neck pain have superficial cervical flexor muscle strength and decreased left hip internal and external rotation muscle strength, and the superficial cervical flexor and extensor muscle strength is unbalanced. Strengthening the superficial cervical flexor muscle strength, improving the balance between the superficial cervical flexor and extensor muscles, and enhancing the hip internal and external rotator muscle strength may help prevent neck pain.
