Are you interested in testing an App developed at BU and designed to lower blood pressure?

We are continuing to recruit for 2 studies involving our Brythm App, designed at BU. Brythm is based on the principles of slow and deep breathing that have been found to lower blood pressure. Our previous research supports the idea that changing the way you breathe has an impact upon your heart rate and blood pressure. We have developed an App (called Brythm) to exploit the beneficial influence of breathing, which guides users to a personalised, optimal breathing frequency.

We are currently conducting one study on healthy women in a laboratory setting to test the cardiovascular responses to slow and deep breathing, which would require approx 2 hours of your time. The other study involves using the App daily at home for 8 weeks to test the feasibility of using the App. For both studies participants will receive information about their current blood pressure.

Lab Based Cardiovascular Responses Study

Participants must be female non-smokers of reproductive age (18-49 years) who are not currently pregnant. They must also have no prior medical diagnosis of cardiovascular or respiratory disease (including asthma). The entire study requires a single visit to the Cardiorespiratory Research Laboratory in Bournemouth House (3rd floor) lasting approximately 2 hours. During this visit you will be asked to undertake a number of 5-minute sets of slow and deep breathing, guided by our App, while a series of non-invasive and painless cardiovascular measurements are made. The App will be installed on our iPad in the lab and you will not be required to use your own device.

At Home 8-week Feasibility Study

Participants must be aged 40 or over and you must have access to an iOS or Android device capable of downloading and running the Brythm App. More details on device specifications available on request. You will be expected to complete daily 10-minute sessions using the Brythm App for 8 weeks and will have an initial meeting with our Project Manager prior to commencing the study, where you will be given a demonstration of the Brythm App and be given an opportunity to try it for a few minutes. You will also receive an automated blood pressure monitor to take home with you for the duration of the study; you will be asked to use it to make two measurements each day, which will be recorded via the Brythm App. Following the intervention we will ask you to attend a focus group where you will be invited to share your experiences of using the App.
