Effect of ice application to head and spine on autonomic function in patients with hypertension: A randomized controlled trial protocol

Background: Hypertension is characterized by persistently elevated blood pressure in the systemic arteries. The global prevalence and incidence of hypertension are on the rise and need to explore various therapeutic interventions to manage this condition effectively. One such intervention is the application of ice application, particularly to the head and spine, which has been studied for its potential effects on blood pressure and heart rate variability. Objective: To evaluate the effect of Ice application to the head and spine on autonomic function in patients with hypertension. Methods: The proposed study is a randomized controlled trial comparing ice application to the head and spine with the control group. A total of 60 participants will be randomly divided into a study group (n=30) and a control group (n=30). The intervention group will undergo ice application to the head and spine. Participants in the control group will be advised to rest in the prone position for 20 minutes. Outcome measurements: Heart rate, heart rate variability, and blood pressure will be assessed immediately before and after the intervention. Conclusion: The results will confirm the effect of Ice application to the head and spine on autonomic function in patients with hypertension
