![]() ![]() There was a moderate although weaker and non-significant negative correlation between deep cervical flexors and anterior scalene activity (r = -0.34 P = 0.053). The range of craniocervical flexion at each of the five test stages was also measured.Ī moderate negative correlation was identified (r = -0.45 P < 0.01) between the average normalized EMG amplitude of the deep cervical flexors and sternocleidomastoid across all stages of the craniocervical flexion test. ![]() Higher activity of the superficial flexors has been interpreted as an indicator of reduced deep flexor activity in people with neck pain but how close the inverse relationship is during this test is unknown.ĮMG was recorded from the sternocleidomastoid, anterior scalene and deep cervical flexor muscles to quantify their relationship during the craniocervical flexion test, from 32 women (age: 38.0 ± 11.6 yrs) with a history of chronic non-specific neck pain. Ideally, electromyography (EMG) studies measure activity in both deep and superficial (sternocleidomastoid, anterior scalene) flexors during the test, but most studies confine recordings to superficial muscle activity as the technique to record the deep muscles is invasive. ![]() The craniocervical flexion test assesses the deep cervical flexor muscles (longus capitis, longus colli). ![]()
