EFFECT OF SCJ MOBILIZATION ON FORWARD HEAD POSTURE

Abstract

Forward head posture (FHP) is a prevalent postural abnormality characterized by the anterior positioning of the head relative to the body's center of gravity. This misalignment is often observed in populations with sedentary lifestyles, such as individuals engaged in prolonged computer use or desk work. The biomechanical repercussions of FHP are substantial, leading to increased stress on the cervical spine, heightened risk of neck pain, and diminished range of motion (Ruivo et al., 2017). These changes disrupt the normal alignment and function of the cervical spine and surrounding musculature, potentially precipitating chronic pain and functional limitations. The sternoclavicular joint (SCJ) assumes a pivotal role in the biomechanics of the shoulder girdle and upper thorax, exerting influence over the position and movement of the head and neck. Dysfunction or restricted mobility in the SCJ can contribute to postural deviations like FHP by altering the mechanics of the clavicle and scapula. Manual therapy techniques aimed at the SCJ, such as mobilization and manipulation, aim to restore its optimal function and improve overall posture (Weon et al., 2010). These techniques may involve specific maneuvers to enhance SCJ mobility and stability, thereby potentially correcting postural abnormalities linked to FHP. Recent studies have indicated that restoring SCJ mobility can positively influence the alignment of the clavicle and scapula, which in turn affects the positioning of the cervical spine and head. By addressing SCJ dysfunction through targeted manual therapy, clinicians may mitigate the biomechanical factors contributing to FHP and associated musculoskeletal issues. However, the specific role of SCJ mobilization in directly correcting FHP remains a subject of ongoing research. Preliminary evidence suggests that integrating SCJ mobilization into comprehensive treatment plans for FHP may yield promising outcomes in terms of posture correction and symptom relief. Clinicians typically assess SCJ mobility through palpation and range of motion tests, tailoring treatment strategies based on individual patient needs and presenting symptoms. This chapter aims to explore the effects of SCJ mobilization on forward head posture through a synthesis of existing research and clinical evidence. By examining the mechanisms, efficacy, and practical application of SCJ mobilization, we seek to provide insights that can inform clinical practice and contribute to the development of effective intervention strategies for managing FHP and related musculoskeletal conditions.
