Effect of Breathing and Muscle Relaxation Technique in Individual With Essential Hypertension

Not Applicable

Completed

• Conditions: Essential Hypertension
• Interventions: Other: Slow Breathing Exercise (SBE); Other: Progressive Muscle Relaxation (PMR) Technique

• Registration Number: NCT05684666
• Lead Sponsor: King Saud University

Brief Summary

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.

Detailed 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.

Arm && Interventions

Group	Intervention	Description
SBE Group	Slow Breathing Exercise (SBE)	Slow Breathing Exercise (SBE) was performed by the participants of SBE group. Sixteen participants included in this group.
Combined Group	Slow Breathing Exercise (SBE)	Sixty participants from the combined group performed both Slow Breathing Exercise and Progressive Muscle Relaxation technique in this study.
PMR Group	Progressive Muscle Relaxation (PMR) Technique	Progressive Muscle Relaxation (PMR) Technique was performed by the participants of the PMR group. It included 16-participants for the study.
Combined Group	Progressive Muscle Relaxation (PMR) Technique	Sixty participants from the combined group performed both Slow Breathing Exercise and Progressive Muscle Relaxation technique in this study.

Primary Outcome Measures

Name	Time	Method
Perceived Stress (PS)	8 Weeks	Perceived Stress was assessed using the perceived stress scale (PSS) with ten items, each with a five-point Likert scale (where a score of 0 indicates "never," a score of 1 indicates "nearly never," a score of 2 "occasionally," a score of 3 "very often," and a score of 4 "often").
Systolic Blood Pressure (SBP)	8 Weeks	SBP was measured using a portable electronic sphygmomanometer.
Respiratory Rate (RR)	8 Weeks	RR was measured manually as the number of breaths a participant takes per minute.
Diastolic Blood Pressure (DBP)	8 Weeks	DBP was measured using a portable electronic sphygmomanometer.
Heart Rate (HR)	8 Weeks	Heart Rate was measured using a portable electronic sphygmomanometer.
