Summary

In this double-blinded study, the objective is to determine the effects of bilateral High Velocity Low Amplitude (HVLA) technique on L3/L4 joint in baropodometric pressures in 60 healthy young adults.

Detailed description

The postural control it´s a fundamental aspect to understand the human´s capacity to perform activities. These balance is controlled by several mechanisms such as the proprioceptive system of muscles and articulation joints. It is known that the High Velocity Low Amplitude (HVLA) technique shows biomechanical and neurophysiologic effects. By saying that, it is importance to understand the effects of the lumbar manipulation on body´s weight distribution. Therefore, there is going to be measure several variables such as center of pressure oscillation , plantar pressure distribution and plantar contact area using a pressure platform.

Conditions

• Healthy

Interventions

Type	Name	Description
OTHER	HVLA L3/4	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.
OTHER	Sham	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.
