Weakness of which muscle group results in the head moving off the table with capital extension during combined cervical flexion testing?

The capital flexors comprise a group of muscles primarily responsible for flexing the head at the atlanto-occipital joint. During combined cervical flexion testing, the assessment of capital flexor strength is crucial. When there is weakness in the capital flexors, it can lead to ineffective control of head movement and stabilization.

In the scenario described, if the capital flexors are weak, the head may not be able to maintain contact with the examination table when flexing the cervical spine. This can result in the head extending backward or moving away from the table, which illustrates an inability to control the desired motion due to insufficient strength in that muscle group. Strong capital flexors typically allow for effective head flexion, keeping the head still and stable during the testing.

Understanding the function of the capital flexors is essential for interpreting the results of cervical flexion testing. Therefore, recognizing their role in maintaining head position during flexion can assist in providing more tailored interventions for individuals with cervical dysfunctions.
