<![CDATA[Hypertension is a cardiovascular disorder characterized by persistently elevated blood pressure and can lead to serious complications if not properly managed. One non-pharmacological intervention that can be used to lower blood pressure is isometric handgrip exercise. This study aimed to determine the effect of isometric handgrip exercise on reducing blood pressure in hypertensive patients in the Inpatient Ward of RSIJ Cempaka Putih. The study used a pre-experimental one-group pretest–posttest design with a sample of 30 respondents. Blood pressure measurements were taken before and after the intervention. Normality testing using the Shapiro–Wilk test showed that both systolic and diastolic blood pressure data had p-values < 0.05, indicating that the data were not normally distributed. Therefore, the analysis was continued using the Wilcoxon Signed-Rank Test. The results showed that isometric handgrip exercise reduced blood pressure in the majority of respondents. The Wilcoxon test yielded p = 0.001 for systolic blood pressure and p = 0.001 for diastolic blood pressure, indicating a statistically significant effect of isometric handgrip exercise on blood pressure reduction (p < 0.05). Thus, isometric handgrip exercise can serve as a simple, safe, and effective non-pharmacological intervention to help control blood pressure in patients with hypertension.]]>
