Details and patient eligibility

About

The purpose of this study is to determine whether Assisted Autogenic Drainage (AAD) or bouncing combined with Assisted Autogenic Drainage (BAAD), induces or aggravates acid and non-acid gastro-oesophageal reflux in infants under the age of one year. Infants, referred to the hospital for impedance-pH monitoring are included in this study.

Enrollment: 105 patients

Sex: All

Ages: 1 to 365 days old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Each child under the age of 1 year, referred for 24 h impedance monitoring to confirm a clinically suspected diagnosis of pathological GOR will be included

Exclusion criteria

• prematurity (gestational age less than 37 weeks),
• the use of anti-reflux medication and reflux surgery (Nissen fundoplication)

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

AAD

Experimental group

Description:

AAD is an airway clearance technique for infants based upon the principles of autogenic drainage. By modulating manually the functional breathing level within the vital capacity, optimal airflow will be obtained at the targeted airway generations, where secretions have been identified. A gentle increase of manual pressure on the chest during each inspiration is performed to guide the breathing of the patient towards the desired lung volume level. During expiration the breathing movement of the patient is followed gently.

Treatment:

Other: AAD

BAAD

Experimental group

Description:

AAD is an airway clearance technique for infants based upon the principles of autogenic drainage .AAD sometimes leads to crying or resistance against therapy.Bouncing (at low amplitude:6-8 cm) in a stable upright position is a gentle up-and-down movement on a physio ball. It is not an ACT, but used to maximize the relaxation of the infant, avoiding resistance against or crying during treatment. Due to the relaxing effect of bouncing, infants appear to tolerate better AAD, increasing the effectiveness of the treatment.
