Study Description
Brief Summary:
The purpose of this study is to determine whether adding load to slow controlled breathing training could enhance blood pressure lowering in patients with essential hypertension.

Condition or disease Intervention/treatment
Essential Hypertension Device: ULB , LB

Detailed Description:
Hypertension (HT) is one of the major risk of cardiovascular diseases and cost of pharmacological treatment is a very high. Lifestyle modification is the first trial in stage 1 hypertension before commencing pharmacological treatment and a co-treatment with drug in hypertensive patient. Slow paced breathing training and physical training has been shown to reduce both systolic and diastolic blood pressure in HT. Moreover loaded breathing was reported to be able to decrease blood pressure in healthy. Loaded slow breathing training may enhance the antihypertensive effect of slow paced breathing.

Study Design

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 30 participants
Allocation: Randomized
Intervention Model: Factorial Assignment
Masking: None (Open Label)
Primary Purpose: Supportive Care
Official Title: Effects of Loaded Breathing Training on Blood Pressure in Essential Hypertensive Patients
Study Start Date : May 2006
Primary Completion Date : December 2007
Estimated Study Completion Date : December 2008
Arms and Interventions

Arm Intervention/treatment
No Intervention: control
The patients in this control group do not conduct any breathing training.
Experimental: ULB
The patients conduct controlled slow breathing training using the WPTB device without inspiratory resistance.
Device: ULB , LB

ULB: The patients breath in slowly without resistance via the water pressure threshold breathing (WPTB) device, 30 min/day, 7 days/week for 8 weeks.

LB : The patients breath in slowly against resistance of 20 cmH2O provided by the water pressure threshold breathing (WPTB) device, 30 min/day, 7 days/week for 8 weeks.

Other Names:
  • Guided breathing training
  • Paced breathing training
  • Controlled breathing training
Experimental: LB
The patients breath in against resistance using WPTB device.
Device: ULB , LB

ULB: The patients breath in slowly without resistance via the water pressure threshold breathing (WPTB) device, 30 min/day, 7 days/week for 8 weeks.

LB : The patients breath in slowly against resistance of 20 cmH2O provided by the water pressure threshold breathing (WPTB) device, 30 min/day, 7 days/week for 8 weeks.

Other Names:
  • Guided breathing training
  • Paced breathing training
  • Controlled breathing training


Outcome Measures

Primary Outcome Measures :
  1. Home blood pressure [ Time Frame: Pre- and post - 8 weeks of intervention at rest ]

Secondary Outcome Measures :
  1. Office blood pressure [ Time Frame: Pre- and post- 8 weeks of intervention at rest ]
  2. Exercising blood pressure [ Time Frame: Blood pressure during exercise at pre- and post-8 weeks of intervention ]
  3. Heart rate variability [ Time Frame: Heart rate variability at pre-and post- 8 weeks of intervention ]
