About this study
To investigate the neurophysiological relationship between Central Conduction Time measured via Somatosensory evoked potentials and pain intensity in individuals suffering from chronic neck pain
Read the detailed description
The explicit lack of direct studies linking Central conduction time to Central pain syndrome in Chronic neck pain, coupled with strong evidence for central sensitization as a key mechanism in CNP and the defining characteristic of CPS, points to a significant diagnostic gap. Somatosensory evoked potential serves as a valuable neurophysiological marker for the structural integrity and conduction velocity of central neural pathways, its direct relationship to the functional dysregulation seen in central pain syndrome in the context of chronic neck pain has not been explicitly established.

Questions about this trial
What is this clinical trial studying?
An observational study of Chronic Neck Pain, run by Cairo University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 4 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: opening soon, as of the sponsor's last update on 13 Jul 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Salah Eid Ahmed Ali, Assistant Lecturer (+201158125773, salaheid07@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Chronic Neck Pain (time frame: at the begining of assessment). 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 13 Jul 2026; AzTrials last refreshed its copy on 26 Oct 2026.
