Summary
Self-perception of neck posture while texting on mobile phones is reliable. Physiotherapists
Area of Science:
- Biomechanics
- Public Health
- Ergonomics
Background:
- Growing mobile phone use in poor postures (text neck) is hypothesized to increase neck pain prevalence.
- Reliable tools are needed to assess text neck for epidemiological studies.
Purpose of the Study:
- To evaluate the reliability of self-perceived text neck posture.
- To assess the reliability of physiotherapists' classification of text neck posture.
Main Methods:
- A cross-sectional study of 113 high school students (18-21 years old).
- Participants completed a questionnaire rating their perceived neck posture while texting.
- Physiotherapists classified participants' habitual texting posture from lateral photographs into four categories.
Main Results:
- Self-perception of neck posture demonstrated substantial test-retest reliability (kappa = 0.73).
- Physiotherapists' classification reliability was moderate (kappa = 0.50) across three raters.
- 76% of participants with objectively appropriate posture self-reported inappropriate posture.
Conclusions:
- Self-perception of neck posture during mobile phone use is reliable over time.
- Physiotherapists' photographic classification is acceptable for epidemiological research.
- Individuals tend to overestimate the severity of their poor neck posture.

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

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
5.6K
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...

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...
