Introduction:
Forward head posture is one of the most common postural disorders affecting the head and neck region, and it is typically assessed based on the craniovertebral angle. Various factors may be associated with the magnitude of this angle. The primary aim of the present study was to investigate the correlation between pain and flexor and extensor muscles endurance and size with craniovertebral angle changes during prolong sitting task.
Methods:
This study included 110 participants. The variables of pain, muscles endurance, muscles size, and the magnitude of the craniovertebral angle were measured using the visual analog scale, muscle endurance tests, ultrasonography, and Image J software, respectively. Additionally, a 30-min seated observation of a video content was employed as the postural task.
Results:
The results demonstrated a significant correlation between craniovertebral angle changes with the intensity of neck pain (p = 0.001) as well as the size of the sternocleidomastoid muscle (p = 0.016).
Conclusions:
Participants who exhibited increased forward head posture following the postural task also demonstrated greater neck pain intensity and increased thickness of the sternocleidomastoid muscle.

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...
