During the Craniocervical Flexion Test, what indicates a positive test?

A positive result during the Craniocervical Flexion Test is indicated by the inability to increase pressure in the cuff. This test is designed to assess the control of the deep cervical flexor muscles. In healthy individuals, these muscles should be able to initiate and sustain increased pressure while maintaining a proper head and neck posture.

When a patient fails to increase the pressure in the cuff, it suggests inadequate activation or control of these muscles, which can indicate potential dysfunction in the neck region. This is particularly relevant in the assessment of patients with cervical instability or neck pain, as poor control of the deep cervical flexors can contribute to symptoms and affect overall cervical spine function.

Other options refer to different situations or symptoms not directly related to the purpose of the test. For example, substitution patterns would indicate compensation strategies rather than a definitive test result. Similarly, pain over the radial side of the wrist and flexion of the distal phalanx are not relevant indicators for determining the performance during this specific neck function assessment. Therefore, the inability to increase pressure in the cuff is the key indicator of a positive test result in the context of evaluating deep cervical flexor strength and control.
