L3/L4 High Velocity Low Amplitude Technique Influence On Baropodometric Pressures In Healthy Young Adults

"The participant will be lateral decubitus and the investigator will locate the third lumbar vertebra. Then with one hand the investigator will contact the interspinous space underlying L3 and with the other hand he will take the top leg into flexion until the investigator feels tension in L3/L4 joint. Then he puls the tables´s arm until felling tension in the region to be manipulated. Afterwards the investigator will globally rotate the participant in the horizontal plane and will approach to the L3/L4 joint. With one arm the investigator will contact the deltopectoral groove and with the other one will contact the external iliac fossa. Finally, the investigator will compress and rotate the pelvis and will apply an impulse in a rapid rotation, without losing the parameters with a body drop allowed by the flexion of the knees and the contraction of the large pectorals."

The participant will be in lateral decubitus and the top leg and knee will be flexed until the foot reaches the popliteal region of the other leg. There won't be applied any tension in no structure. This intervention will be applied during 20 seconds each side.
