Forward head posture is linked to increased neck pain and sternocleidomastoid muscle size. Prolonged sitting can worsen these postural issues, impacting craniovertebral angle and discomfort.
Area of Science:
- Biomechanics
- Ergonomics
- Musculoskeletal Health
Background:
- Forward head posture is a prevalent postural disorder affecting the head and neck.
- The craniovertebral angle is a key metric for assessing forward head posture.
- Several factors can influence the craniovertebral angle.
Purpose of the Study:
- To examine the relationship between craniovertebral angle changes and neck pain.
- To investigate the correlation between muscle endurance and size with craniovertebral angle.
- To assess these factors during a prolonged sitting task.
Main Methods:
- 110 participants were included in the study.
- Measurements included pain (visual analog scale), muscle endurance, muscle size (ultrasonography), and craniovertebral angle (Image J software).
- A 30-minute seated video observation served as the postural task.
Main Results:
- A significant correlation was found between craniovertebral angle changes and neck pain intensity (p=0.001).
- Craniovertebral angle changes also correlated significantly with sternocleidomastoid muscle size (p=0.016).
Conclusions:
- Increased forward head posture after prolonged sitting is associated with heightened neck pain.
- Individuals with increased forward head posture showed greater sternocleidomastoid muscle thickness.

Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
