Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to investigate the immediate effects of atlanto-occipital joint mobilization on head posture, respiratory function, and cervical range of motion in healthy individuals with forward head posture.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Forward head posture (FHP) is a common postural disorder characterized by the anterior displacement of the head relative to the shoulders. The estimated prevalence of FHP among individuals who use electronic devices frequently is reported to be high, affecting a significant portion of the general population. While postural correction exercises and ergonomic education are generally the first-line management strategies for FHP, manual therapy techniques (such as joint mobilizations and soft tissue therapy) are often recommended as an adjunct treatment. Additionally, various physiotherapy approaches, including stretching of the posterior cervical muscles, strengthening of the deep neck flexors, and respiratory exercises, can also be utilized. Specific mobilization of the atlanto-occipital joint is theorized to normalize arthrokinematics and reduce fascial restrictions in the suboccipital region. This is said to decrease neuromuscular tension, improve proprioceptive input, and restore optimal alignment, resulting in positive effects on head posture, cervical mobility, and respiratory function.
