About this study
The study will be a multi-center, randomized clinical trial to evaluate the safety and efficacy of using the Zona Plus handgrip therapy device compared to the use of an auditory relaxation therapy for treatment of high blood pressure and hypertension in subjects who are not currently taking antihypertensive medications. Half of the study subjects will also be randomized to record blood pressure at home throughout the study.
Read the detailed description
Study subjects randomized to the Zona Plus Device arm will perform isometric therapy with the device with subject compliance monitored through a downloadable electronic memory function built into the device. Study subjects randomized to the control arm will be asked to listen to relaxing music via a mobile app and asked to document their compliance via a patient diary. Subjects in the control arm may be able to crossover to using the Zona Plus device after completion of Study Visit 6. Subjects who have systolic blood pressure between 140mmHG and 149mmHG at baseline will complete three additional study visits for further monitoring. Subjects can expect participation in the study to last between 3 and 8 months.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Zona Plus DeviceDevice
Use of the Zona Plus device involves performing isometric handgrip exercise therapy. Isometric exercise is the type of exercise in which you tense or tighten your muscle without seeing it change in length.
Relaxing Music AppOther
Relaxing music will be made available through a mobile app that users access via their smart phone or tablet. Subjects will have the option to listen to 5 different music genres that support relaxation (Classical, Nature, Movie Soundtracks, Jazz, Reggae).
| Study group | Role | What they receive |
|---|---|---|
| Investigational | Experimental | Zona Plus Device Receives: Device: Zona Plus Device |
| Control | Active comparator | Relaxing music Receives: Other: Relaxing Music App |
What is being measured
The primary outcome is the main question the study is designed to answer.
Compare the change from baseline in mean seated cuff systolic blood pressure (SBP) after 10 weeks of treatment between patients randomized to the Zona Plus device and the patients in the control group.
Measured: 10 weeks
Secondary outcomes (3)
To compare the change from baseline in seated cuff diastolic blood pressure ("DBP") after 10 weeks of treatment between patients randomized to the Zona Plus device and the patients in the control group.
Measured: 10 weeks
The percentage of patients randomized to the Zona Plus device who achieve a clinically significant SBP reduction (defined as ≥5 mmHg) at Week 10 compared to control.
Measured: 10 weeks
The percentage of patients randomized to the Zona Plus device who achieve a clinically significant DBP reduction (defined as ≥3 mmHg) at Week 10 compared to control.
Measured: 10 weeks
