Cervical Extensor Endurance Test

The Cervical Extensor Endurance Test is a great way to assess cervical extensor strength. It also helps you distinguish between weakness of superficial neck extensors and weakness of deep cervical flexor muscles.

Weak neck extensors lead to stiffness and aching in the neck area. It may also lead to kyphosis, or an excessive forward rounding of the upper back, which eventually lead to other issues like back pain, limited physical function, weakness, limited range of motion, fatigue, balance issues, or even digestive or respiratory problems.

The Cervical Extensor Endurance Test requires the examinee to hold the chin-tuck position for 20 seconds. The test is negative if the patient holds for 20 seconds, and it is positive if the patient loses the chin tuck, whether it goes into neck flexion and/or if the patient's chin lengthens.
