Summary
Individuals with neck pain exhibit impaired trunk-head coordination, showing reduced trunk mobility and increased head movement. This suggests difficulties in maintaining head stability during trunk motion, potentially linked to altered sensorimotor control.
Area of Science:
- Biomedical Engineering
- Neuroscience
- Kinesiology
Background:
- Neck pain is associated with reduced neck motion and sensorimotor deficits.
- Altered reflex mechanisms involving the neck, eyes, and vestibular system are hypothesized.
- Trunk-head coordination may be impaired in individuals with neck pain.
Purpose of the Study:
- To investigate trunk-head coordination in subjects with persistent neck pain.
- To compare trunk-head coordination abilities between neck pain patients and healthy controls.
Main Methods:
- Twenty-four neck pain subjects and 26 healthy controls participated.
- Participants performed trunk movements while attempting to maintain head stillness.
- Wireless motion sensors measured trunk and head range and velocity.
Main Results:
- Neck pain subjects demonstrated significantly reduced trunk movement and velocity.
- Significantly increased head movement was observed in neck pain subjects during most tasks.
- Tasks were performed more slowly by the neck pain group.
Conclusions:
- Neck pain is linked to impaired ability to move the trunk independently of the head.
- Individuals with neck pain struggle to stabilize the head during trunk movements.
- Findings suggest potential alterations in cervico-collic reflex and sensorimotor control.

01:26Arteries of the Head and Neck
3.2K
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
5.6K
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...

For transition metal complexes, the coordination number determines the geometry around the central metal ion. Table 1 compares coordination numbers to molecular geometry. The most common structures of the complexes in coordination compounds are octahedral, tetrahedral, and square planar.

In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...

02:33Lattice Centering and Coordination Number
11.6K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes...
