What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this project is to compare the performance and validity of novel wearable technologies that measure blood pressure (BP) and physical activity with a Spacelabs Ambulatory Blood Pressure Monitoring (ABPM) device.

Are You a Good Fit for This Trial?

This trial is for individuals in the Boston area who can consent, walk with two limbs, have two arms, and are willing to complete measurement procedures. It's designed for those with hypertension or normal blood pressure interested in testing wearable BP monitors.

Inclusion Criteria

I can understand and agree to the study's procedures and risks.

I live in the Boston area.

I am willing and able to follow through with all required tests and procedures.

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

What Are the Treatments Tested in This Trial?

Interventions

• ABPMPro
• Aktiia Blood Pressure
• Bpro
• LiveMetric
• Spacelabs Ambulatory Blood Pressure Monitoring

Trial Overview The study compares new wearable blood pressure technologies (ABPMPro, Aktiia Blood Pressure Monitor, LiveMetric, Bpro) against a standard device (Spacelabs ABPM) to check their accuracy and performance in measuring BP and physical activity.

How Is the Trial Designed?

Group I: Wristband sequence (first day versus second day) Experimental Treatment 3 Interventions

Participants will be randomized 1:1 to wear (A) the LiveMetric wristband on the first day and Bpro wristband on the second day or (B) Bpro wristband on the first day then LiveMetric wristband on the second day. The arm side (i.e., right or left) will be determined by the Aktiia cuffless blood pressure device randomization on the first day. For the second day, the Aktiia cuffless blood pressure device will be worn on the arm opposite the first day with the other device (LiveMetric versus Bpro) worn on the contralateral arm.

Group II: Left versus right upper limb Experimental Treatment 3 Interventions

Participants will be randomized to wear the Aktiia cuffless blood pressure device on either the left upper limb versus the right upper limb on the first day. On the second day, the Aktiia blood pressure device will be switched to the other arm which did not get randomized on the first day. Another wristband (LiveMetric versus Bpro) will be worn on the contralateral arm.

Group III: Cuff-based ambulatory blood pressure monitor sequence Experimental Treatment 2 Interventions

Participants will be randomized 1:1 to wear (A) the Spacelabs ambulatory blood pressure monitor on the first day and ABPMPro ambulatory blood pressure monitor on the second day or (B) ABPMPro ambulatory blood pressure monitor on the first day then Spacelabs ambulatory blood pressure monitor on the second day.
