Comparative Effects Of Eye-Cervical Re-Education Exercises And Pressure Biofeedback Training Of Deep Cervical Flexors In Cervicogenic Headache

Summary

Cervicogenic headache (CGH) is a secondary headache that originates from dysfunction in the upper cervical spine, particularly the atlanto-occipital and C1-C3 segments, and is perceived in one or more regions of the head and/or face. The underlying mechanism involves convergence of cervical and trigeminal afferents in the trigeminocervical nucleus. Structures innervated by the C1, C2, and C3 spinal nerves are capable of producing referred pain to the head. CGH is relatively common, accounting for approximately 15-20% of all chronic headaches. It typically worsens with neck movement and is often associated with limited cervical range of motion. One of the key impairments in individuals with CGH is disrupted cervical sensorimotor control, particularly affecting proprioception and deep cervical muscle coordination. Physical therapy is widely recognized as the first-line treatment for CGH, with emerging evidence supporting interventions aimed at improving cervical proprioception and neuromuscular control. This study aims to compare the effectiveness of two sensorimotor-based physical therapy approaches-eye-cervical re-education and pressure biofeedback training of deep cervical flexors (DCF)-in patients with CGH. The primary outcomes include pain intensity, functional disability, cervical range of motion (ROM), and cervical joint position sense (proprioception). Participants will be recruited using purposive sampling from Fauji Foundation Hospital and Foundation University College of Physical Therapy (FUCP), Islamabad. After providing written informed consent, eligible participants will be randomized into two groups. Group 1 will receive conventional physical therapy along with eye-cervical re-education exercises, while Group 2 will receive conventional therapy combined with pressure biofeedback DCF training. Data will be collected at baseline and after the 10th treatment session to assess within- and between-group changes in the outcome measures. This study aims to inform evidence-based physical therapy practice in the management of cervicogenic headache.

Conditions

• Cervicogenic Headache

Interventions

PROCEDURE

Eye cervical re-education exercises

Eye cervical re education exercises targeting cervical pain, ROM, neck disability index and joint proprioception. Conventional Physical Therapy Protocol: Hot pack Isometric exercises are applied with sustain 5 sec in all cervical motion with ten repetitions for each direction while the patient sits in erect position and the therapist stood back of the patient. SNAGS are applied for 5 to 6 times. Eye cervical re-education exercises: This program composed of ten exercises for re-training of proprioceptive input in the cervical spine through the three following phases: a) Ocular mobility without cervical movement phase b) Cervical mobility exercises phase c) Eye-cervical co-ordination exercise phase

PROCEDURE

Pressure biofeedback training of deep cervical flexors

It is performed in supine crook position. The neck is aligned in a neutral position. The pressure biofeedback unit is centered just below the occiput between the plinth and the back of the neck and inflated to a baseline of 20 mmHg. Each subject is asked to gently and slowly execute the head nodding action (as if they said yes) at five different levels of pressure (22, 24, 26, 28 and 30 mmHg) and to maintain each level for 10 seconds There was a 30-second rest period between each level. The test protocol ended when the subject is unable to hold the same pressure level for 10 sec or reached a peak level of 30mmHg.
