Muscles that Move the Head01:19

Muscles that Move the Head

5.8K
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...

Arteries 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...

Veins of Head and Neck01:19

Veins of Head and Neck

5.5K
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...

Kinematic Equations - I01:26

Kinematic Equations - I

15.1K
When an object moves with constant acceleration, the velocity of the object changes at a constant rate throughout the motion. The kinematic equations of motions are derived for such cases where the acceleration of the object is constant. The first kinematic equation gives an insight into the relationship between velocity, acceleration, and time. We can see, for example:

Kinematic Equations - II01:17

Kinematic Equations - II

13.6K
The second kinematic equation expresses the final position of an object in terms of its initial position, the distance traveled with the initial constant velocity, and the distance traveled due to a change in velocity. Similar to the first kinematic equation, this equation is also only valid when the acceleration is constant throughout the motion of an object.
Suppose a car merges into freeway traffic on a 200 m long ramp. If its initial velocity is 10 m/s and it accelerates at 2 m/s2, then the...

Kinematic Equations for Rotation01:30

Kinematic Equations for Rotation

801
In mechanics, when one observes a rigid body in rotational motion with constant angular acceleration, it is possible to establish equations for its rotational kinematics. This process resembles how linear kinematics are dealt with in simpler motion studies.
For instance, imagine a point A on a rigid body engaged in circular motion. The translational velocity of this particular point can be calculated by taking the time derivatives of the displacement equation, which essentially measures the...

Area of Science:

  • Biomechanics
  • Human-Computer Interaction
  • Neuroscience

Background:

  • Accurate head motion tracking is crucial for virtual reality (VR) applications in postural studies.
  • Investigating normal and pathological head kinematics requires portable and precise tracking methods.
  • Head-mounted displays (HMDs) offer potential for accessible head motion analysis.

Purpose of the Study:

  • To assess the concurrent validity of head tracking from Oculus Rift and HTC Vive against a gold-standard motion capture system.
  • To quantify head kinematics during static and dynamic postural tasks using VR HMDs.
  • To determine the reliability and agreement of HMD-based head tracking for postural assessments.

Main Methods:

  • Twenty healthy young adults performed static and dynamic postural tasks in VR environments.
  • Head kinematics were simultaneously recorded using Oculus Rift, HTC Vive, and a Qualisys motion capture system.
  • Measures included head directional path, 6-directional acceleration, and translation volume, analyzed with Intra-Class Correlations (ICC) and Limits of Agreement.

Main Results:

  • High ICC values (around 0.9 to 0.99) indicated excellent agreement between HMDs and the gold-standard system for most head kinematics.
  • Weaker agreement was noted for vertical displacement in static tasks and moderate agreement for pitch/yaw in dynamic tasks.
  • A small negative bias (more movement in VR) was observed in static tasks, while a positive bias (less movement in VR) occurred in dynamic tasks.

Conclusions:

  • The Oculus Rift and HTC Vive demonstrate strong concurrent validity for head tracking during static and dynamic postural tasks in healthy young adults.
  • VR HMDs provide a viable tool for measuring head kinematics in research settings.
  • Task- and direction-specific differences in tracking accuracy should be considered when utilizing these VR technologies for postural analysis.
