Key result
HY SENAR nerve stimulation reduces systolic blood pressure by ~20 mmHg versus standard care.
Why the study?
Hypertension in the elderly increases cardiovascular risk and is worsened by anxiety-induced sympathetic nerve activity, creating a need for effective, easy-to-apply non-pharmacological interventions such as Hypertension Simple Electrical Nerve Stimulation by Smartphone (HY SENAR).
Does smartphone-controlled electrical nerve stimulation (HY SENAR) reduce blood pressure and anxiety scores in elderly patients with hypertension compared to standard care?
Does smartphone-controlled electrical nerve stimulation (HY SENAR) reduce blood pressure and anxiety scores in elderly patients with hypertension compared to standard care?
A 4-week regimen of smartphone-controlled peripheral electrical nerve stimulation (HY SENAR) significantly reduced systolic and diastolic blood pressure as well as anxiety scores compared to standard care in elderly patients with hypertension.

HY SENAR was associated with greater systolic BP reduction in elderly hypertension; leaves open efficacy and safety pending randomized trials.
Hypertension in the elderly is a major health problem that increases the risk of cardiovascular disease. In addition to physiological factors, anxiety can trigger an increase in sympathetic nerve activity thereby worsening blood pressure. Effective and easy-to-apply non-pharmacological interventions are needed, one of which is Hypertension Simple Electrical Nerve Stimulation by Smartphone (HY SENAR). Analyze the effect of the use of HY SENAR on blood pressure and anxiety scores in the elderly with hypertension. Quasy experimental design with a pretest-posttest with control group. A total of 44 respondents were selected by purposive sampling and divided into intervention groups (HY SENAR with 10 Hz) and control (standard treatment of health centers). The intervention was administered three times a week in four weeks for twenty minutes. Data analysis used paired t-test, independent t-test, wilcoxon signed rank, mann whitney, and RLG tests. HY SENAR significantly lowered systolic blood pressure, diastolic, and anxiety scores in the elderly with hypertension (p 0.001), with greater reductions than in the control group. The difference in decreased systolic (MD=19.82 mmHg) and diastolic (MD=9.64 mmHg) blood pressure showed significant results. Multiple linear regression analysis also showed that HY SENAR intervention had a significant effect on lowering blood pressure and anxiety (p0.001). HY SENAR intervention with a frequency of 3 times a week for 4 weeks had the effect of reducing systolic blood pressure, diastolic, and anxiety in the elderly with hypertension. HY SENAR has the potential to be applied as an additional non-pharmacological intervention in health centers because it is practical and can be done independently.

ABSTRAK Hipertensi pada lansia merupakan masalah kesehatan utama yang meningkatkan risiko penyakit kardiovaskular. Selain faktor fisiologis, kecemasan dapat memicu peningkatan aktivitas saraf simpatis sehingga memperburuk tekanan darah. Diperlukan intervensi non-farmakologis yang efektif dan mudah diterapkan, salah satunya Hypertension Simple Electrical Nerve Stimulation by Smartphone (HY SENAR). Menganalisis pengaruh penggunaan HY SENAR terhadap tekanan darah dan skor kecemasan pada lansia dengan hipertensi. Penelitian ini menggunakan desain quasy experimental dengan pretest-posttest with control group. Sebanyak 44 responden yang dipilih secara purposive sampling dan dibagi menjadi kelompok intervensi (HY SENAR dengan 10 Hz) dan kontrol (perlakuan standar puskesmas). Intervensi diberikan sebanyak tiga kali seminggu dalam empat minggu selama dua puluh menit. Analisis data menggunakan uji paired t-test, independent t-test, wilcoxon signed rank, mann whitney, dan RLG. HY SENAR secara signifikan menurunkan tekanan darah sistolik, diastolik, dan skor kecemasan pada lansia dengan hipertensi (p0,001), dengan penurunan yang lebih besar dibandingkan kelompok kontrol. Perbedaan penurunan tekanan darah sistolik (MD = 19,82 mmHg) dan diastolik (MD=9,64 mmHg) menunjukkan hasil yang signifikan. Analisis regresi linear ganda juga menunjukkan bahwa intervensi HY SENAR berpengaruh signifikan terhadap penurunan tekanan darah dan kecemasan (p 0,001). Intervensi HY SENAR dengan frekuensi 3 kali dalam seminggu selama 4 minggu berpengaruh menurunkan tekanan darah sistolik, diastolik, dan kecemasan pada lansia dengan hipertensi. HY SENAR memiliki potensi untuk diterapkan sebagai tambahan intervensi non-farmakologis di puskesmas karena praktis dan bisa dilakukan mandiri.

Afifah et al. (2026) studied Hypertension and anxiety in the elderly (n=44). Hypertension Simple Electrical Nerve Stimulation by Smartphone (HY SENAR) vs. Standard health center treatment (Puskesmas standard care) was evaluated on Reduction in systolic blood pressure (mmHg) (MD 19.82 mmHg, 95% CI 16.74-22.90, p=<0.001). HY SENAR electrical nerve stimulation significantly reduced systolic blood pressure compared to standard care in elderly patients with hypertension (MD 19.82 mmHg, 95% CI 16.74-22.90; p<0.001).
