About

Primary hypertension, also called essential hypertension, is a rise in blood pressure (BP) with no identifiable cause. The most prevalent form of hypertension is essential hypertension, which involves 95% of patients with hypertension.Progressive muscle relaxation (PMR) is learning to relax some groups of muscles while paying attention to the feelings connected with both the tense and relaxed states.It is generally established that regular slow (deep) breathing exercises enhance respiratory and cardiovascular function by enhancing parasympathetic tone and reducing sympathetic activity, thus reducing BP, heart rate, respiratory rate, and stress levels in hypertensive patients. This study aimed to investigate the combined effect of slow breathing and PMR technique on BP, heart rate, respiratory rate, and anxiety in patients diagnosed with essential hypertension.

Full description

From the previously published literature, it is obvious that both slow breathing and PMR and slow breathing is effective in patients with essential hypertension. However, no studies are available on the combined effect of these two techniques. So, the study aims to investigate the combined effect of slow breathing and PMR technique on BP, heart rate, respiratory rate, and anxiety in patients diagnosed with essential hypertension.

Sixty-four participants diagnosed with essential hypertension were randomly allocated into four groups (Slow breathing (SB), PMR, SB+PMR, Control) with 16 subjects in each. Baseline BP, HR, RR and perceived stress scale were taken. All three-intervention groups underwent 30 minutes of training three days before the day of the intervention. The intervention consisted of 30 minutes, pre, mid and post-intervention BP, HR, RR and Perceived Stress (PS) were measured. The control group rested for 30 minutes. Pre, mid and post-rest measurements of BP, HR, RR and PS were taken.
