Estimating the efficacy of isometric handgrip training to lower resting blood pressure in patients with stage 1 hypertension in Eastern Uganda compared to standard of care: study protocol for a randomized controlled trial [PDF]

open access: yesTrials
Background Hypertension (HTN) is a major non-communicable disease worldwide, including in Uganda. Studies have estimated HTN prevalence in Uganda between 19 and 33% among adults, with only 7–9% controlled within clinical target ranges. Isometric handgrip
