Variation of the respiratory volumes in the asthmatic subject after the rotation sitting impulse technique of the dorso-lumbar junction.

Osteopathic treatment: Rotation sitting impulse technique of the dorso-lumbar junction bilaterally technique of high velocity, low amplitude in the dorso-lumbar junction known in osteopathy as "Fryette modified technique for dysfunction in T12 ERS." The aim of the technique is to increase lung volumes by restoring mobility at this level, where the diaphragmatic pillars are originated. Subject Position: Sitting, hands placed like lift-off technique. Therapist position: forward to a side of the subject. Contacts: pectoral contact on the outside of the upper side of the subject, locking the trunk. The previous hand contact on the back of the shoulder encircling the trunk of the subject and the elbow raised to rest his forehead. The back hand takes a pisiform contact ulnar border of the hand on the nested facet of T12 The technique is administered on a single occasion, but bilaterally The duration of the tecnique is less than a minute (30 seconds approximately)
