Area of Science:

• Cardiology
• Integrative Medicine
• Physiology

Background:

• Complementary and alternative medicine (CAM) is utilized for anti-aging and disease management.
• Reflexology, a CAM modality, involves stimulating reflex points on the feet and hands.
• Autonomic nervous system (ANS) modulation is crucial in cardiovascular health.

Purpose of the Study:

• To investigate the impact of foot reflexology (FR) on autonomic nervous system modulation in patients with coronary artery disease (CAD).
• To assess changes in heart rate variability (HRV) parameters following FR.
• To compare the effects of FR on ANS modulation between CAD patients and healthy controls.

Main Methods:

• A study involving 20 patients with CAD and 17 healthy controls.
• Heart rate variability (HRV) analysis was employed to measure ANS modulation.
• Normalized high-frequency power (nHFP) for vagal modulation and normalized very low-frequency power (nVLFP) for sympathetic modulation were assessed.

Main Results:

• Foot reflexology significantly increased vagal modulation (nHFP) and decreased sympathetic modulation (nVLFP) in both groups.
• Blood pressure (systolic, diastolic, mean arterial, and pulse pressures) decreased significantly after FR in both groups.
• The magnitude of change in autonomic nervous modulation was slightly smaller in CAD patients compared to controls.

Conclusions:

• Foot reflexology effectively enhances vagal modulation and reduces blood pressure in both healthy individuals and CAD patients.
• FR shows potential as an adjunctive therapy for improving cardiovascular autonomic function.
• The study highlights the benefits of FR in managing autonomic dysfunction in CAD.
