Summary
Forward head posture is linked to poorer cervical proprioception, meaning individuals with this posture have a greater error in repositioning their head. This highlights a connection between head alignment and sensory feedback in the neck.
Area of Science:
- Physiotherapy
- Biomechanics
- Neuroscience
Background:
- Cervical proprioception is crucial for head and neck movement control.
- Altered head posture, such as forward head posture, is common and may affect sensorimotor function.
- Understanding the relationship between head posture and proprioception is important for rehabilitation strategies.
Purpose of the Study:
- To investigate the correlation between head posture and proprioceptive function in the cervical region.
- To determine if craniovertebral angle is associated with cervical joint position sense error.
Main Methods:
- Seventy-two subjects (35 males, 37 females) were assessed.
- Head posture was measured using the craniovertebral angle (CVA).
- Cervical joint position sense was evaluated using a dual digital inclinometer for flexion and extension repositioning error.
Main Results:
- A significant negative correlation was found between CVA and position sense error for both cervical flexion and extension.
- Subjects with a smaller CVA (indicating forward head posture) exhibited greater repositioning errors.
Conclusions:
- Forward head posture is associated with impaired cervical proprioception, characterized by increased repositioning error.
- These findings suggest that head posture may influence the accuracy of head movement sense.
- Further research is warranted to explore the therapeutic implications of correcting forward head posture on proprioceptive deficits.

01:19Muscles that Move the Head
6.8K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

01:28Articulations of the Vertebral Column
3.6K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

01:28Major Somatic Sensory Pathways
3.3K
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

01:16Vertebral Column: Regions and Curvature
11.5K
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

01:29The Vestibular System
45.0K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

01:15Equilibrium and Balance
7.7K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...
