About

This study were to investigate the effects of balloon blowing breathing exercise on respiratory muscle strength and asthma symptoms in school-age children with asthma.

Full description

Thirty school-age children with asthma aged 7 - 12 years old who were admitted at the outpatient examination room, Phramongkutklao Hospital, divided into 2 groups. The first group was 15 individuals trained with sustained maximal inspiration (SMI) breathing exercise while the second group was 15 individuals training with balloon-blowing breathing exercise. Participants were required to complete breathing exercise 5 times per week for 8 weeks. Five breathing exercises were taken for 8 weeks before and after the experiment. Physiological characteristics data, pulmonary function, respiratory muscle strength, and asthma symptoms variables were comparatively analyzed before and after training. The mean values of variables before and after the experiment of each group were analyzed using paired t-test.

Enrollment: 30 patients

Sex: All

Ages: 7 to 12 years old

30 participants in 2 patient groups

Balloon-blowing breathing

Experimental group

Description:

1. Start by measuring the vital capacity using a balloon to determine. The width of the balloon diameter for each blow and used the value to make a balloon size control device to give to the sample group and parents to use it for home training. 2. Participant sit on a chair. Inhale fully through their nose and hold for a full 3 second inhalation, then exhale through their mouth into the balloon fully. By having the balloon inflate until their touch the balloon size control device and hold the exhalation period for 1 second, cover the balloon immediately with your fingers count as 1 breath cycle, then replace the balloon immediately. Do this for 3 consecutive rounds, counted as 1 set, in each training, do a total of 3 sets, rest between sets for 1 minute, which takes about 15 minutes, 5 times per week for 8 weeks

Treatment:

Other: Balloon-blowing breathing

Sustained maximal inspiration breathing

Experimental group

Description:

Participants sitting in a chair, back and head close to the wall. Inhale through their nose fully and hold for 3 seconds for a full breath, then slowly exhale through their mouth and hold for 1 second of exhalation, counted as 1 breathing cycle.Do this 3 times in a row for 1 set. Practice each time doing a total of 3 sets, with 1 minute rest between sets. Participants were required to complete breathing exercise 5 times per week for 8 weeks.

Treatment:

Other: Sustained maximal inspiration breathing
