Abstract：
OBJECTIVE: To find out the normative value of deep neck flexor muscles strength using pressure biofeedback unit and sphygmomanometer.
METHODS: The healthy individuals both male and female aged between 18 and 25 years were recruited by stratified random sampling method from a tertiary hospital. The procedure is performed with the patient in supine lying with the neck in a neutral position. To check strength, pressure biofeedback unit and sphygmomanometer were placed under occiput and ask the individual to do the movement is genteelly and slowly as a head nodding action (chin tuck). The performance was scored via the pressure level that patient achieves 3 repetitions for 10 s hold and interval timing for 10 s. And the pressure biofeedback unit and sphygmomanometer inflated with 40 mmHg and took three reading respectively.
RESULTS: Our result shows, in decreased of deep neck cervical flexor muscle Strength with age group 21 (20-22) in normal adult and underweight with age group 21 (19-23) and with BMI 21 (20.1-22.4) and 16.6 (16.1-17.6) respectively. In our study, the deep neck flexor strength of overweight adults with age group 22 (21-23) and with BMI 27.8 (25.9-29.4) is stronger is than the normal and underweight adults.
CONCLUSIONS: The study concluded that the maximal Deep neck cervical flexor strength of overweight Adults is stronger than normal and underweight Adults. The difference is maintained in all age groups. The maximal Deep neck cervical flexor strength, for flexion is developed at neutral position of neck.

摘要：
目的：使用压力生物反馈单元和血压计找出颈深屈肌力量的标准值。
方法：采用分层随机抽样的方法从某三甲医院抽取18~25岁的男性和女性健康个体。该过程是在患者仰卧，颈部处于中立位置的情况下进行的。为了检查强度，压力生物反馈装置和血压计被放置在枕骨下，并要求个人做运动是温和和缓慢的头点头动作（下巴缩）。通过患者在10s内保持3次重复并间隔10s的压力水平对性能进行评分。压力生物反馈单元和血压计以40mmHg充气并分别读取3次读数。
结果：我们的结果显示，在21岁（20-22岁）的正常成年人和21岁（19-23岁）和BMI21（20.1-22.4）和16.6（16.1-17.6）的体重不足中，颈深屈肌力下降。在我们的研究中,22岁(21-23岁)和BMI为27.8(25.9-29.4)的超重成年人的颈深屈肌强度比正常和体重不足的成年人更强.
结论：该研究得出的结论是，超重成年人的最大颈颈屈肌强度强于正常和体重不足的成年人。差异在所有年龄组都保持不变。最大颈深屈力量，屈曲发展在颈部的中立位置。
