About this study
Official title: Study to Examine the Hemodynamic Responses in Hemodialysis Patients to Blood Flow Restriction Using Non-pneumatic Anti-shock Garments
Study comparing different groups of people and how they respond to application of the non-pneumatic anti-shock garments. Investigators will divide all recruited participants into three groups based on health status (group 1: hemodialysis patients; group 2: patients with severe chronic kidney disease but not on dialysis; group 3: healthy participants with no clinically known kidney disease). Each group, which will comprise of 10 people, will receive the same treatment using the non-pneumatic anti-shock garments.
Read the detailed description
Primary Aim: To determine how blood flow restriction to the lower extremities using non-pneumatic anti-shock garments affects hemodynamic and cardiovascular parameters such as blood pressure in Hemodialysis (HD) patients while they are not on dialysis.
Investigators propose a pilot study to assess the effects of blood flow restriction using non-pneumatic anti-shock garments in HD patients while they are not on dialysis.
Outcomes: The primary objective will be a measurement of blood pressure upon application of the non-pneumatic anti-shock garments.
Secondary outcomes will include the following: baroreflex sensitivity; trends in beat-to-beat blood pressure upon application of the anti-shock garments; patient tolerability of the non-pneumatic anti-shock garments, ejection fraction via echocardiogram analyses.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Application of Antishock garmentDevice
anti-shock garments are applied. Participants will then be examined for two 15 minute intervals with and without the anti-shock garments applied. During each 15 minute interval, echocardiograms will be performed.

Questions about this trial
What is this clinical trial studying?
A study testing Application of Antishock garment in people with Blood Pressure, run by London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's 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 9 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

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?
Assessment of blood pressure changes with and without garment application (time frame: Participants will be examined for two 15 minute intervals with and without the anti-shock garments applied. During each 15 minute interval, echocardiograms will be performed.). 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 NCT02915627, 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 25 Jan 2018; AzTrials last refreshed its copy on 7 Nov 2026.
