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.
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.

Craniovertebral Angle (CVA) for Forward Head Posture
Forward head posture will be assessed by measuring the craniovertebral angle (CVA) using a goniometer. The CVA is the angle between the horizontal line passing through the C7 spinous process and the line from the tragus of the ear to the C7 spinous process.
Time frame: Assessments will be performed at baseline (before the application) and immediately following the single-session intervention.
Respiratory Function assessed by Spirometry (FVC, FEV1, FEV1/FVC, PEF, FEF25-75%)
Respiratory function will be assessed using a spirometry device. The following parameters will be recorded and analyzed: Forced Vital Capacity (FVC), Forced Expiratory Volume in one second (FEV1), the FEV1/FVC ratio, Peak Expiratory Flow (PEF), and Forced Expiratory Flow at 25-75% of FVC (FEF25-75%).
Time frame: Assessments will be performed at baseline (before the application) and immediately following the single-session intervention.
Cervical mobility (Cervical Range of Motion (CROM)) assessed by Bubble Inclinometer
Cervical mobility (range of motion) will be assessed using a bubble inclinometer. Active range of motion will be measured in degrees for the movements of flexion, extension, lateral flexion (left/right), and rotation (left/right).
Time frame: Assessments will be performed at baseline (before the application) and immediately following the single-session intervention.
