Correlation Between Smartphone Use and Text Neck Posture in Asymptomatic Subjects

July 12, 2024 updated by: Hend Hesham Abd Elfatah Ali, Cairo University
This study will be conducted to investigate the correlation between the number of hours of smartphone usage and severity of text neck posture, cervical ROM, DNF endurance and resting head posture among asymptomatic 18 to 25 years old adults

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Smartphone use has increased significantly globally, with 79% of adults aged 18-44 carrying a smartphone constantly. This can cause excessive anterior curves in the neck vertebrae and increase the mechanical load on cervical spine joints. Overuse syndrome, spinal damage, and other side effects can result. This study aims to investigate the correlation between time spent using smartphones and text neck posture and its association with head and neck posture, cervical ROM, and DNF endurance among asymptomatic 18-25-year-olds.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Assessing the average duration of smartphone screen time
Time Frame: at baseline
A mobile application called Screen Time Restrain Yourself measures smartphone usage in hours over the past week, allowing users to monitor their daily usage without disrupting normal smartphone use.
at baseline

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Assessment of head and neck posture
Time Frame: at baseline
Photogrammetry is a reliable method for measuring head and cervical spine postures. It involves taking sagittal photographs of the subject's head tilt angle and neck tilt angle. A camera is positioned at a height corresponding to the seventh cervical vertebra (C7) level, and spherical markers are attached to the right tragus, canthus, and spinal process. The subject is instructed to sit on a chair, maintain a resting head posture, and perform full flexion and extension three times. The average of angles from repeated photos is used to reduce bias. Fatigue time is reported after ten minutes of use with a smartphone.
at baseline
Assessment of cervical range of motion
Time Frame: at baseline
Cervical ROM is measured using a universal goniometer, with subjects placed flat on the floor and supported on a lap. They move their head in flexion and extension, with the goniometer placed over the external auditory meatus, fixed arm perpendicular to the floor, and movable arm with the nose base. For cervical rotation, they turn the head to the left or right side, and for lateral flexion, they touch the ear to a shoulder of the same side. The goniometer is a valid and reliable tool for measuring cervical ROM, with good interrater and intraterrater reliability.
at baseline
Assessment of deep neck flexor endurance
Time Frame: at baseline
The Neck Flexor Muscle Endurance Test (NFMET) involves a subject supine, with hands resting on the abdomen and feet flat on a plinth. The subject performs chin retraction, head and neck lift, and skin folds. The test measures muscle endurance, with males having a longer average hold time than females.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
July 1, 2023

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
