Effects of Electrical Stimulation on Blood Pressure
1. Tu et al. (2021): Home-based TEAS + Medication Cuts Blood Pressure by 8.5 mmHg
This randomized controlled trial involved 60 patients with hypertension already on medication. Half were assigned to continue usual care. The other half used a TEAS (Transcutaneous Electrical AcupointStimulation) device daily for 15 minutes, similar in principle to Therava. After 12 weeks, the TEAS group experienced an additional 8.5 mmHg reduction in systolic blood pressure compared to the control group.
Takeaway: Using a device like Therava alongside lifestyle changes or meds can amplify the effects, safely and non-invasively.
2. Giollo-Junior et al.(2023): Neck TENS Reduced Blood Pressure in a Drug-Resistant Patient
This single-patient case study might sound small, but the impact was big. A middle-aged man with severe, medication-resistant hypertension used TENS therapy on the lower neck (C7-T4 region) three times per week. After one month, his systolic blood pressure dropped from 154 mmg to 136 mmg without changing medication.The researchers also observed improved arterial stiffness, a key factor in heart disease risk.
Takeaway: If TENS can help someone whose blood pressure didn't respond to four medications, imagine what it could do for those in earlier stages.
3. Cipriano et al. (2014):Cervical Stimulation Improves Circulation After Heart Surgery
In this randomized trial, patients recovering from coronary bypass surgery were split into two groups: one received standard care, the other got daily 30-minute TENS therapy on the neck and upper back. Within five days, the TENS group showed significantly lower blood pressure spikes.
Even more fascinating? They walked farther in post-op rehab and needed less pain medication.
• Takeaway: Therava-style therapy may help restore autonomic balance and improve circulation even in high-risk heart patients.
4. Yang et al. (2024): Low-Intensity TENS on the Neck Slows Blood Flow and Reduces Strain
In a recent study published in Healthcare(MDPI), researchers applied low-frequency TENS to the neck area of 31 healthy adults. The results were subtle but impressive: even below-threshold stimulation led to a 2% reduction in carotid artery peak blood velocity.
Why does that matter? Because lower flow velocity typically reflects decreased vascular resistance, a good sign for long-term heart health. Importantly, the device used was non-invasive and safe, reinforcing that gentle neck stimulation can relax arterial tension without medications.
• Takeaway: Even healthy individuals can benefit from soft electrical pulses near the carotid artery, supporting the Therava use case for preventative health.
5. Chen et al. (2022): TEAS Effectively Regulated Preoperative Blood Pressure in Hypertensive Patients
In this randomized controlled trial, 91 gynecological malignant tumor patients with hypertension were divided into TEAS and control groups. The TEAS group received transcutaneous electrical acupoint stimulation at Neiguan and Hegu points before surgery.
Results showed that TEAS effectively regulated preoperative blood pressure and significantly reduced preinduction hypertension compared to the control group.
Takeaway: Non-invasive electrical stimulation can acutely manage blood pressure in clinical settings, demonstrating immediate cardiovascular benefits.
6. Li et al. (2015): Long-Lasting Reduction of Blood Pressure by Electroacupuncture in Patients with Hypertension (RCT)
This well-designed randomized controlled trial examined 65 unmedicated hypertensive patients who received electroacupuncture at select acupoints. The study demonstrated significant, long-lasting reductions in both systolic and diastolic blood pressure.
Remarkably, the blood pressure reductions persisted even after the treatment period ended, suggesting lasting cardiovascular benefits.
Takeaway: Electrical stimulation therapy can produce sustained blood pressure improvements that extend beyond the active treatment phase.
