Randomized controlled trial comparing suboccipital release and smartphone app-guided exercises on pain, disability, craniovertebral angle and cervical ROM in 52 participants with smartphone neck syndrome over 4 weeks.

Smartphone neck syndrome, commonly referred to as text neck syndrome, is a musculoskeletal condition characterized by neck pain, stiffness, and postural dysfunction resulting from prolonged smartphone use. Sustained neck flexion during smartphone viewing increases mechanical stress on the cervical spine, particularly affecting the upper cervical segments and suboccipital musculature. Repetitive forward head posture (FHP) leads to adaptive shortening of posterior cervical muscles, overstretching of anterior cervical structures, altered joint biomechanics, and progressive muscular imbalance. .Biomechanically, forward head posture increases the load on the cervical spine. As the head moves anteriorly, the gravitational moment arm increases, leading to greater compressive forces on the cervical vertebrae and increased tension in the suboccipital muscles. Continuous activation of these muscles to counterbalance the forward weight of the head results in muscle fatigue, trigger point formation, reduced cervical range of motion (ROM), and pain sensitization. Over time, these alterations may contribute to joint stiffness, decreased mobility, and functional disability. The craniovertebral angle (CVA) is widely used as an objective measure of forward head posture. A reduced CVA (less than 50 degrees) indicates increased anterior head translation and postural deviation. Decreased CVA has been associated with higher levels of neck pain, muscle tightness, and functional impairment. Additionally, individuals with smartphone neck syndrome commonly demonstrate limited cervical ROM in flexion, extension, rotation, and lateral flexion, along with increased pain intensity and disability scores. Suboccipital muscle dysfunction plays a central role in smartphone neck syndrome. The suboccipital muscles (rectus capitis posterior major and minor, obliquus capitis superior and inferior) are responsible for fine motor control and stabilization of the atlanto-occipital and atlanto-axial joints. Prolonged flexion posture increases their resting tension and reduces local circulation, potentially leading to ischemia and heightened nociceptive input. Manual therapy techniques such as suboccipital release aim to reduce muscle hypertonicity, improve local blood flow, modulate pain through mechanoreceptor stimulation, and restore normal cervical biomechanics. On the other hand, exercise-based interventions focus on correcting muscle imbalance and improving neuromuscular control. Chin tucks, suboccipital stretching, and craniovertebral nodding exercises strengthen deep neck flexors, lengthen tight posterior muscles, enhance cervical alignment, and promote long-term postural correction. These exercises also contribute to improved proprioception, muscular endurance, and motor control, which are essential for maintaining cervical stability during daily activities. Physitrack mobile application will be used for app guided exercises. Recent advancements in digital health technologies have introduced smartphone application-guided rehabilitation programs. Applications such as Physitrack provide structured exercise protocols, instructional videos, reminders, adherence tracking, and feedback mechanisms that enhance patient compliance and self-management. App-guided exercise programs are cost-effective, accessible, and promote continuity of care beyond clinical settings. Evidence suggests that smartphone-based rehabilitation demonstrates strong reliability and validity in monitoring performance and improving musculoskeletal outcomes. Despite availability of both passive manual therapy and active exercise-based interventions, limited research directly compares the effectiveness of suboccipital release and smartphone app-guided exercises in individuals with smartphone neck syndrome. Passive techniques may provide immediate pain relief and muscle relaxation, whereas active exercise programs may offer long-term improvements in posture, motor control, and functional ability. Therefore, this study aims to compare the effects of suboccipital release and smartphone app-guided exercises on craniovertebral angle, cervical range of motion, pain intensity, and functional disability in adults with smartphone neck syndrome. The findings of this study may contribute to evidence-based physiotherapy practice by identifying the more effective intervention approach for managing postural dysfunction and neck pain associated with prolonged smartphone
