Brief 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.

Eligibility criteria: Inclusion Criteria:

* Individuals aged between 18-25 years old;
* Individuals with BMI between 18,5 and 24,9 kg/m2

Exclusion Criteria:

* Pregnancy;
* With the follow conditions: lumbar discal hernia, spondylolisthesis with neurologic influence, narrowing of medullar canal, rheumatic disease, orthopaedic or neurologic conditions such as diminished sensibility, lack or absence of muscular strength, absence of patellar and/or aquilus reflexes;
* History of chirurgical intervention either on lumbar or lower limbs in the past 6 months;
* History of any trauma on the lumbar spine or lower limbs in the past 6 months;
* Any type of treatment on the lumbar in the previous month: that implicates physiotherapy, osteopathy, chiropractic, myofascial treatment, acupuncture or others;
* Medication that affects the vestibular system (dizziness, vertigo and humming)
* Pain during que experimental study;
* Difference between the length of the lower limbs: above 1.5cm;

Primary outcomes:
measure: Change from Baseline of center of pressure displacement after intervention
timeFrame: Immediately after the intervention
Secondary outcomes:
measure: Change from Baseline of plantar pressure mean
timeFrame: Immediately after the intervention
measure: Change from Baseline of plantar contact area
timeFrame: Immediately after the intervention
