Rationale: Breathing pattern disorders (BPD) are well known to be the cause of different negative effects, psychological, biological and neurological, due to the condition of respiratory alkalosis they can bring and automatically increasing levels of anxiety and apprehension and, consequentially, alter the normal motor control of skeletal musculature and of balance. Diaphragmatic and transversus abdominis tone are key features to provide core stability in presence of any alteration in the support offered to the spine by the muscles of the torso, or any “block” occurring to the diaphragm because of bad posture or compulsory use of the breathing accessory muscles, the tonic and phasic functions of both the diaphragm and transversus abdominis are reduced or absent after about 1 min of hypercapneoa. Many cases of anxiety have been found having their origin not in psychological issues but in BPD. Breathing rehabilitation (BR) helps to reduce the negative influences resulting from BPD

Results: we have dealt with 13 cases of anxiety which was strongly reduced or resolved, through BR. 9 of these patients had been treated with anxiolytic drugs (alprazolam, diazepam and bromazepam) for weeks, or even months with no success; the other 4 used to take anxiolytic drugs only occasionally when the anxiety was uncontrollable by other methods. All patients were introduced to a project of BR, after a period, variable from 3 to 8 weeks, of rehabilitation 11 patients had resolved the problem and no anxiety or panic had shown again. The other 2 reported to be symptom-free after 10 and 12 weeks.
