Brief summary: The purpose of the study is to explore the effectiveness of Suboccipital muscle inhibition technique vs Rocabado exercises on cervicogenic headache. A randomized control trial was conducted at National Institute of Rehabilitation Medicine, Alees Medical Centre Islamabad. The sample size was 40 calculated through G-power 3.1. The participants were divided into two interventional groups each having 20 participants. The study duration was six months. Sampling technique applied was non-probability purposive sampling for recruitment and group randomization using flip coin method. Only 20 to 50 years participants with chronic cervicogenic headache were included in the study. Tools used in this study are Digital Inclinometer, Numeric Pain Rating Scale, Romberg Test and HIT-6 Questionnaire. Data was collected at baseline, and at the end of 2nd week. Data analyzed through SPSS version 27.

Detailed description: Cervicogenic headache is a type of secondary headache that originates from cervical spine dysfunction, particularly involving the upper cervical segments. It is frequently unilateral and is often accompanied by neck stiffness and reduced cervical range of motion. The pain typically radiates from the occipital or suboccipital region to the frontotemporal or retro-orbital areas. It is commonly described as dull and non-throbbing. Cervicogenic Headache constitutes about 14-18% of all chronic headaches, making it a significant concern in musculoskeletal and neurologic clinical practice. The condition often leads to impaired quality of life and mild to moderate disability. Manual therapy and therapeutic exercises are widely used in physiotherapy for management.

The suboccipital region plays a crucial role in postural stability and dural tension regulation due to the presence of myodural bridges between the suboccipital muscles and the dura mater. Dysfunction in these structures can contribute to pain and sensorimotor disturbances in Cervicogenic headache. Suboccipital Muscle Inhibition is a manual technique aimed at relieving tension in these muscles and restoring balance. The technique involves sustained pressure applied to the suboccipital area, helping reduce nociceptive input and improving cerebral spinal fluid flow. Studies have found Suboccipital Muscle Inhibition effective for headache relief and postural improvement. It is recognized for promoting muscular relaxation and decreasing headache intensity. However, more comparative evidence is needed.

Cervical postural alignment plays a significant role in managing musculoskeletal conditions such as cervicogenic headaches. Poor posture, particularly forward head posture, can place excessive strain on the upper cervical spine, contributing to headache symptoms and muscular imbalance. To address these postural deficits, Dr. Mariano Rocabado developed the 6×6 exercise protocol, a structured program aimed at restoring proper cranio-cervical alignment. The protocol includes six exercises performed six times per session, repeated six times daily. These exercises target key elements such as tongue posture, cervical spine control, axial extension, and scapular stabilization. By promoting postural awareness and neuromuscular coordination, the protocol supports improved cervical mechanics. It has been shown to be effective in reducing tension, enhancing movement control, and optimizing cervical posture in individuals with postural dysfunctions.

This study aims to compare the effectiveness of the Suboccipital Muscle Inhibition technique and Rocabado 6×6 exercises in managing cervicogenic headaches. It hypothesizes that both interventions will produce improvements, but one may yield superior outcomes in terms of pain reduction, cervical range of motion, and balance. A randomized clinical trial will be conducted involving 40 participants divided equally into two groups. One group will receive SMI with conventional therapy, and the other will perform Rocabado exercises alongside conventional treatment. The treatment duration will consist of six sessions over two weeks. Both subjective and objective outcome measures will be employed to assess changes.

Participants will be assessed using tools like the Numeric Pain Rating Scale for pain intensity, the Flexion Rotation Test for cervical rotation dysfunction, and the HIT-6 for headache-related disability. Balance will be evaluated using the Romberg test, and cervical Range of motion will be measured with a digital inclinometer. Participants eligible for the study will include adults aged 24-50 years with a history of Cervicogenic headache for over three months. Strict inclusion and exclusion criteria will be followed to ensure sample validity. Patients using pain medication or having contraindications to manual therapy will be excluded. The outcome will be measured before and after the intervention.

Both groups will receive the same conventional treatments such as moist heat, cervical stretching, strengthening exercises, and manual traction. Group A will additionally receive the Suboccipital Muscle Inhibition technique applied for 10 minutes in each session. Group B will perform the Rocabado 6×6 protocol, with one supervised session and five sessions conducted independently each day. All treatments are expected to alleviate pain and restore cervical biomechanics. The hypothesis is that direct dural and postural modulation through Suboccipital Muscle Inhibition may show faster effects, while Rocabado's protocol may offer long-term neuromuscular control benefits. Comparative effectiveness will be analyzed using SPSS software with appropriate statistical tests.

The research is expected to fill the gap in literature regarding the comparative effectiveness of these two distinct but relevant approaches in treating Cervicogenic headache. A clearer understanding of their benefits can guide clinicians in personalizing care for patients with Cervicogenic headache, potentially combining the strengths of both methods. The study also aims to provide cost-effective, non-pharmacological management options that reduce headache recurrence, enhance cervical function, and improve patient quality of life. By establishing evidence-based guidelines, this research may influence future physical therapy protocols and headache rehabilitation strategies, ensuring optimized outcomes for Cervicogenic headache sufferers.
