Effect of two breathing exercises (Buteyko and pranayama) in asthma: a randomised controlled trial.

BACKGROUND: Patients with asthma are interested in the use of breathing exercises but their role is uncertain. The effects of the Buteyko breathing technique, a device which mimics pranayama (a yoga breathing technique), and a dummy pranayama device on bronchial responsiveness and symptoms were compared over 6 months in a parallel group study. METHODS: Ninety patients with asthma taking an inhaled corticosteroid were randomised after a 2 week run in period to Eucapnic Buteyko breathing, use of a Pink City Lung Exerciser (PCLE) to mimic pranayama, or a PCLE placebo device. Subjects practised the techniques at home twice daily for 6 months followed by an optional steroid reduction phase. Primary outcome measures were symptom scores and change in the dose of methacholine provoking a 20% fall in FEV(1) (PD(20)) during the first 6 months. RESULTS: Sixty nine patients (78%) completed the study. There was no significant difference in PD(20) between the three groups at 3 or 6 months. Symptoms remained relatively stable in the PCLE and placebo groups but were reduced in the Buteyko group. Median change in symptom scores at 6 months was 0 (interquartile range -1 to 1) in the placebo group, -1 (-2 to 0.75) in the PCLE group, and -3 (-4 to 0) in the Buteyko group (p=0.003 for difference between groups). Bronchodilator use was reduced in the Buteyko group by two puffs/day at 6 months; there was no change in the other two groups (p=0.005). No difference was seen between the groups in FEV(1), exacerbations, or ability to reduce inhaled corticosteroids. CONCLUSION: The Buteyko breathing technique can improve symptoms and reduce bronchodilator use but does not appear to change bronchial responsiveness or lung function in patients with asthma. No benefit was shown for the Pink City Lung Exerciser.

[Studies on the use of music therapy as a form of breathing exercise in bronchial asthma].

96 patients suffering was examined. 46 patients over one year was offending kinesytherapy during a special active music therapy techniques was used. It was the form of breathing exercises. 50 patients during the period of one year was under program of traditional breathing kinesytherapy. The authors observed a greater effectiveness of music therapy which decrease bronchial resistances, increases physical self-feeling and reduces anxiety level.

Functional evaluation of a physical rehabilitation program including breathing exercises and bicycle training in chronic obstructive lung disease.

20 patients suffering from chronic obstructive lung disease (COLD) were submitted to a 6-month rehabilitation program including breathing exercises only (A) or coupled with bicycle training (B). Functional results obtained at rest were the following: for A: nonsignificant changes in FRC, RV, FEV1, Raw, Pa O2, pH, Pp, VO2 max SL but significant changes (p less than 0.05)for TLC (+ 214 cm3), VC (+ 171 cm3), DL CO (+ 1.79 ml), Pa CO2 (-2.9 mm Hg). For B: similar changes as for A with additional significant changes in PaO2 (+ 7.4 mm Hg) VO2 max SL (+ 250 ml) and Pp (-4 mm Hg). These results, although minimal, are attributed to improved respiratory muscle strength and improved alveolar ventilation. Exercise training adds an increased ability to sustain higher loads.

Effects of deep breathing exercise and ambulation on pattern of ventilation in post-operative patients.

Deep breathing and ambulation are used by physiotherapists for patients after surgery, however the precise effects of these on ventilation have not been investigated. This study was designed to compare the effects of deep breathing and ambulation on pattern of breathing in patients after upper abdominal surgery. A similar increase was found in minute ventilation, however the pattern of breathing seen during each treatment was very different. During the deep breathing exercises patients had large, significant increases in tidal volume (mean change 488.5ml), while respiratory rate decreased non-significantly. By comparison, ambulation caused small and non-significant increases in both tidal volume (163.4ml) and respiratory rate. It appears that if one of the aims of ambulation is to increase tidal volume, patients may need to be encouraged to augment their tidal volumes.

Emission of extremely strong magnetic fields from the head and whole body during oriental breathing exercises.

This article reports the result of an experiment that was designed to measure the biomagnetic field emanating from two individuals who were practising traditional Oriental Qi Gong breathing exercises. The biomagnetic field was measured with differential coils wound 80,000 turns, a magnetic needle compass and a digital electromagnetic wave detection device. It was found that an extremely strong magnetic field was emitted from the two individuals. One subject emitted a magnetic field at the level of 200-300 mT (2-3 mGauss) and the other at 0.13 mT (1.3 mGauss). In both cases, moreover, the magnetic needle compass rotated 30 degrees (this was tested 32 times). When the rotation of the needle occurred, a reproducible magnetic field of 800-1500 mT (8-15 mGauss) was indicated on the digital measuring device (this was tested 12 times). It is concluded that traditional Oriental Qi Gong breathing appears to stimulate an unusually large biomagnetic field emission.

Comparison of three protocols for breathing exercises during immersion in 38 degrees C water for chronic obstructive pulmonary disease.

Respiratory function test, arterial blood gas analysis, and ejection fraction were used to compare three protocols of breathing exercises during immersion in 38 degrees C water. Therapy was given for 2 mo to patients with stable chronic obstructive pulmonary disease. Protocol A consisted of a total exercise period of 20 min/wk (10 min/day, 2 days/wk) and was performed by 7 patients (5 cases of asthma and 2 cases of emphysema). Protocol B consisted of a total exercise period of 120 min/wk (20 min x 2 per day at 10:00 am and 3:00 pm, 3 days/wk) and was performed by 9 patients (6 asthmas and 3 emphysemas). Protocol C consisted of a total exercise period of 120 min/wk (20 min/day, 6 days/wk) and was performed by 8 patients (4 asthmas and 4 emphysemas). The ratio of forced expired volume in one second to forced vital capacity (FEV1.0%) was significantly increased in protocols B and C (P < 0.01). The ratio of forced vital capacity to the predicted normal value (%FVC) was not changed in any of the three protocols. A significant increase in peak flow was observed in protocols B and C (P < 0.05). The maximal expiratory flow at 25% (V25) was not changed in any of the three protocols. PaO2 was significantly increased and PacO2 was significantly decreased in protocol B (P < 0.01 and P < 0.05, respectively), whereas only PaCO2 was significantly decreased in protocol C (P < 0.05). Ejection fraction was increased in protocols B and C. These results suggest that exercise for a total period of 120 min/wk is preferable to that of 20 min/wk in COPD.

Analysis of breath-by-breath exercise data from field studies.

We describe a system useful for collecting and analyzing breath-by-breath exercise test data in the field. In studies of untrained subjects, analysis of artifacts is particularly important. Our system uses pattern-recognition criteria to reject breaths if the breathing valves do not operate satisfactorily or if deviations from the calibrating baseline occur.
