Cervicogenic headache (CGH) is a secondary headache type caused due to refereed pain arising from the cervical spine in the forehead, sometimes in temporal region. Which may have great impact on our daily life activities; decreased range of motion at cervical spine, decreased sleep quality, increased stress, disturbed mood and altered physiologic chemicals. It is found to be more prevalent in females and is experimentally diagnosed by the Cervical Flexion-Rotation Test (CFRT) which is performed by a therapist. Also, the upper trapezius midpoint (2 cm lateral to C2) mostly acts as a pressure point. Other pressure points in cervical region may also develop. The pain is mostly on one side and remains on one side. It can be dull aching or pressure like pain. No photophobia, phonophobia, nausea, or tearing of eyes is associated with it. In the modern age, smartphone addiction (SPA) contributes significantly to CGH by promoting forward head posture, rounded shoulders, and impaired proprioception. (4)Despite this, there is a clear gap in the literature regarding body awareness, ergonomics, and targeted prevention strategies for smartphone-related postural problems. There is an urgent need for structured training programs and therapeutic interventions to address these concerns, combined with long-term follow-up studies. In this study, investigators focus on brain-derived neurotrophic factor (BDNF) as a key biomarker of pain sensitization. Chronic stress and pain reduce neuronal BDNF uptake, decreasing the serum BDNF levels, while effective interventions are expected to elevate BDNF levels, improving motor performance and reducing nociceptive signaling. Literature shows that there is a significant increase in BDNF levels in moderate intensity aerobic exercise groups as compared to the control group. This study aims to improve BDNF levels through isometric targeted exercise and ultimately improve the synaptic plasticity, mitochondrial activity, increased beta-endorphins. An increase in body temperature through exercise will also reduce pain sensitization and improve function. In this study, we also target stress levels by focusing on cortisol as a biomarker. As the physiological and psychological stress is increased due to prolonged flexion and increased screen tim,e sleep quality is also disturbed. We aim to evaluate whether targeted isometric neck exercises can enhance BDNF levels, regulate cortisol as a stress marker, and ultimately improve CGH symptoms. As we know that high stress elevates cortisol and disrupts the HPA axis, This study was having hypothesis that exercise-induced adaptations will downregulate the HPA axis, decrease cortisol, restore neuronal health, and enhance cognitive and motor functions and we also address how poor sleep, exacerbated by excessive screen time, contributes to cognitive, memory, and metabolic issues. By investigating the effects of exercise on sleep quality, our study fills a crucial research gap linking SPA, stress, BDNF, cortisol, and CGH offering a novel therapeutic approach that combines patient education, circadian rhythm alignment, and structured isometric exercise to improve health outcomes in adolescents.
Smartphone addiction (SPA) increasingly contributes to cervicogenic headaches (CGH) and alters stress biomarkers (cortisol, BDNF) in adolescents. This study aims to evaluate isometric neck exercises' impact on CGH symptoms, cortisol, and BDNF levels in SPA-affected adolescents. It will be a single-blind randomized controlled trial (RCT). This study had a sample size of 44, based on a medium effect size of 0.9 with 80% power. Which include adolescents (13 to 24 years) with SPA and CGH. Intervention: One month of supervised/home-based isometric neck exercises (n=24) versus control (n=24). Outcomes: Primary: Changes in NDI, HIT-6. Secondary: Changes in cortisol, BDNF, PSQI from baseline to 1-month. This RCT will assess if isometric exercises reduce CGH symptoms and modulate key biomarkers such as BDNF informing interventions for SPA-related health issues. The primary outcome for this study was the reduction in Cervicogenic Headache (CGH) symptom burden and associated pain sensitization processes involved in causing CGH. This outcome will be quantified by measuring the change from baseline to 1-month post-intervention using three distinct measures: * The Neck Disability Index (NDI): A questionnaire assessing perceived functional disability related to neck issues. * The Headache Impact Test (HIT-6): A questionnaire evaluating the impact of headaches on daily function. * Serum Brain-Derived Neurotrophic Factor (BDNF) levels: Determined via ELISA analysis, utilized as a biomarker potentially reflecting changes in neuronal plasticity associated with pain sensitization. The secondary outcome will be stress reduction, evaluated via both physiological and subjective indicators linked to stress levels. This will be quantified by measuring the change from baseline to 1-month post-intervention using: * Serum Cortisol levels: Determined via ELISA analysis, serving as a physiological marker of hypothalamic-pituitary-adrenal (HPA) axis activity. * The Pittsburgh Sleep Quality Index (PSQI): A questionnaire assessing subjective sleep quality, considered here as an indicator influenced by overall stress. The Intervention Group (n=22) will participate in supervised exercise sessions twice weekly at the IPMR KMU Physiotherapy Department, each lasting 30 minutes and led by a physiotherapist. These sessions will include specific exercises: TENS (for pain relief): Intensity is typically set to a sensory level, where the patient feels a comfortable tingling or buzzing sensation without muscle contraction. Pulse duration often ranges from 50-100 microseconds, and treatment sessions usually last for 20-30 minutes, performed once or twice daily. Chin tuck in Gently retract chin backward ("double chin") while sitting or standing tall, keeping eyes forward. Low intensity, focusing on controlled muscle activation. Aims to strengthen deep neck muscles, improve posture, and stretch sub occipital muscles. Repetitions 10 times and hold times 10 sec and then released. Isometric exercises involve contracting neck muscles against a fixed resistance (like your hand or a wall) in various directions (flexion, extension, lateral flexion, rotation) for 10-second holds. Performed at a moderate intensity for 10 repetitions, lasting about 15 minutes, this strengthening exercise aims to build neck muscle strength and endurance. Head protrusion in antigravity Lying down with head slightly off the edge, actively lift head to neutral or hold isometrically against gravity for 10 seconds, repeated 5 times at moderate intensity. This exercise strengthens deep neck flexors and improves postural endurance. Wall Push-Ups Standing facing a wall with hands shoulder-width apart, lean in by bending elbows, then push back. Intensity is moderate. Aims to strengthen chest, triceps, and key scapular stabilizers (serratus anterior, rhomboids, trapezius) for better shoulder posture. Reps 10 times Isometric shoulder shrugs by Standing or sitting tall, the individual actively elevates (shrugs) their shoulders straight up towards their ears, then lowers them back down by holding a weight of intensity is mild to moderate hold for 10 sec and repeat 6-10 times Weight-Bearing Shoulder Flexion: In supine position with both hands holding a stick/ weight raise arm forward and upward for 10 repetitions at moderate intensity. This functional exercise strengthens shoulder flexion and improves scapular/core stability under load, promoting integrated movement. Deep neck flexors engage to stabilize the head and neck against the shifting weight and forces during the arm movement. PNF exercise for deep neck flexors in sitting position tuck chin towards the chest until the participant feels a mild to moderate stretch at the back of neck. The therapist will apply resistance in this position to engage participant deep neck flexors in isometric contraction against the slight resistance for 10 sec then completely relax participant neck muscles. Repeat this isometric contraction and relaxation of deep flexors 6-10 times. Participants will perform the same exercises daily at home for approximately 15 minutes. Patient education on posture and smartphone ergonomics. Adherence will be supported through app reminders and weekly phone check-ins, aiming for over 80% compliance. Where as controlled group will only receive posture advice subjective sleep quality, considered here as an indicator influenced by overall stress.
