About this study
Official title: Untreated Sleep-related Breathing Disorders as an Aggravating Factor for Neuropathic Pain, Spasticity and Cardiovascular Dysfunction After Spinal Cord Injury: A Cross-sectional Prospective Study

What is being measured
The primary outcome is the main question the study is designed to answer.
Apnea-hypopnea index (AHI)
The number of apneas and hypopneas per hour of sleep recorded using the ApneaLink device.
Measured: One night of sleep (up to 10 hours)
Secondary outcomes (3)
Neuropathic pain
Level of neuropathic pain prior to the interventions using Visual Analog Scale (0: no pain; 100: the worst pain ever).
Measured: Pre-intervention assessment only.
Spasticity
Degree of spasticity prior to the interventions using the modified Ashworth Scale (0: normal tone; 16: all four extremities rigid in flexion or extension).
Measured: Pre-intervention assessment only.
Cardiovascular dysfunction
The number of episodes of autonomic dysreflexia during sleep.
Measured: Pre-intervention assessment only.

Questions about this trial
What is this clinical trial studying?
An observational study of Sleep Apnea and Spinal Cord Injuries, run by University Health Network, Toronto at 1 site in Canada.
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 3 inclusion and 6 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 8 May 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 Canada. 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?
Apnea-hypopnea index (AHI) (time frame: One night of sleep (up to 10 hours)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05687097, which also lists 1 linked publication.
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 8 May 2024.
