Summary
Accommodative visual dysfunctions are linked to neck pain and reduced physical function. This study found connections between eye focusing issues and cervical complaints, impacting performance and range of motion.
Area of Science:
- Ophthalmology
- Neurology
- Physical Therapy
Background:
- Cervical complaints and visual dysfunctions are common.
- The relationship between these conditions requires further investigation.
Purpose of the Study:
- To determine the association between accommodative visual dysfunctions and cervical complaints.
- To analyze how specific accommodative measures correlate with neck pain and functional metrics.
Main Methods:
- Fifty-two participants were assessed for accommodative functions (amplitude, NRA, response, facility).
- Cervical complaints were evaluated using the Neck Disability Index, Visual Analogue Scale, cervical range of motion, deep flexor activation, and performance index.
- Participants were categorized into accommodative insufficiency, accommodative excess, or normal groups.
Main Results:
- Significant correlations were found between negative relative accommodation (NRA) and performance index/left-side bending.
- Accommodative amplitude and facility in the right and left eyes showed significant relationships with cervical range of motion (side bending) and performance index.
- Participants with accommodative excess exhibited greater neck pain and reduced right-rotation compared to those with accommodative insufficiency.
Conclusions:
- Accommodative dysfunctions are associated with diminished performance index and reduced cervical range of motion.
- Increased neck pain is linked to accommodative dysfunctions.
- These findings suggest a relationship between visual system function and cervical health.

The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

01:19Veins of Head and Neck
5.8K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

1.9K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Primary motives such as sleep, sex, and pain avoidance are crucial drivers of behavior in humans and animals. These motives ensure survival, reproductive success, and overall well-being by prompting actions that meet essential bodily needs.
Sleep is a fundamental physiological drive that fosters a state of restfulness crucial for several bodily functions. It facilitates body restoration, the process by which the body repairs, rejuvenates, and maintains itself during sleep, including memory...
