Introduction Altered cervical lordosis is one of the cause that provoke cervical pain, osteoarthrits of the cervical and disability. In the area of physical therapy, therapists try to maintain or recovery of normal cervical lordosis, most of all, strengthening exercise of deep cervical flexor muscles is effective and widely used. However there was no study that the effects of degree of cervical lorsosis or pressure of biofeedback unit on activity of cervical flexor muscles. So, the purpose of this study was effects of pressure of biofeedback unit on the activities of cervical flexior muscles during head-neck flexion exercise in three cervical lordosis-normal, kypotic, and Hyperlodrosis. Methods. 30 subjects were no cervical pain, classified three group-normal, kypotic, and Hyperlodrosis-by Inhihare Index. Ultrasonography images of deep flexor and SCM were taken simultaneously to performance of the isometric cervical flexion with maintaining 20, 22, 24, 26, 28, and 30 mmHg pressure of biofeedback unit. Changes in muscle thickness were measured in relation to rest, and results were used to infer on muscle activation. Results. Differences in muscles activity were observed between pressure for deep neck flexor and SCM (F= P< ); being difference significant higher at 30mmHg than the other pressure; being significant higher activation of deep flexor muscle at 24, 26 mmHg in normal group than kypotic groups, and 28, 30 mmHg in Hyperlodrosis group than kypotic group. but there was no difference of SCM activation between groups. Conclusion. Results indicate that head-neck flexion exercise with biofeedback unit is more facilitating of deep cervical flexor muscles, more improving the pressure, at the same time more effective exercise to the people with normal lordosis or Hyperlodrosis curve than kypotic curve.
