A Pivotal Study to Evaluate the Effectiveness of Isometric Handgrip Therapy in Elevated Blood Pressure and Hypertensive Subjects

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.
