About this study
Official title: Correlation Between Forward Head Posture and Cervical Radiculopathy in Smart Phone Users
The progression rate of forward head posture has increased because of the increase in postural loads, to which individuals are subjected because of developed technologies including mobile phones, computers, and televisions. Postural abnormality in the upper cervical region has the potential to lead to nerve irritation and cervical radiculopathy. so the purpose of study is to investigate if there is a relationship between forward head posture and cervical radiculopathy in smart phone users.

What is being measured
The primary outcome is the main question the study is designed to answer.
Somatosensory evoked potential of median nerve
Measured: at the time of enrollment
Secondary outcomes (4)
change in Craniovertebral angle
Measured: At the time of enrollment
Change in cervical range of motion
Measured: At the time of enrollment
Change in pain intensity
Measured: At the time of enrollment
Assessment of cervical function
for assessment of cervical function. we will use Neck disability index which is a 10-items questionnaire that measures a patient's self-reported neck pain related disability. Questions include activities of daily living, such as: personal care, lifting, reading, work, driving, sleeping, recreational activities, pain intensity, concentration and headache.
Measured: At the time of enrollment

Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Somatosensory evoked potential of median nerve (time frame: at the time of enrollment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Sep 2026.
