About this study
A correlation study was conducted to correlate between the convergence insufficiency and postural stability at three different cervical positions in patients with non-specific cervical pain.
Read the detailed description
A correlational study was conducted on eighty (male and female) subjects aged between 30-40 years old, presented with chronic NSCP persisted for six months or more, with neck disability index score (NDI) ≥10%, and can possess at least 45° of left and right cervical rotation participated in the study. Convergence insufficiency was evaluated by the near point of conversion (NPOC) rule and postural instability was examined by the Biodex balance system. RESULTS: There was significant positive correlation between (NPOC) and anteroposterior stability index (APSI) at the three cervical positions; neutral, 45° right torsion and 45° left torsion (P>0.05).

Questions about this trial
What is this clinical trial studying?
An observational study of 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 1 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 1 Nov 2024. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Stability index (time frame: during the procedure). The study lists 3 primary outcomes in all. 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 1 Nov 2024.
