简要总结
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.
详细描述
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.

Each participant will pull from a bag within equally number of folded papers with letter A (Intervention Group) and letter B (Control Group) and it will be handled to the investigator.
The outcome assessors won´t also have any contact with the investigator and participant whilst intervention.

研究组 & 干预措施
HVLA L3/4 Group
In each participant, blind assessors will perform pre-intervention measurements of dislocation of center of pressure (CoP), plantar pressure mean and plantar contact area in a baropodometric pressure platform.
Next, the investigator will perform the HVLA technique in L3/L4 joint articulation.
Then, the same measurements before described will be repeated, by the assessors 1 minute after the intervention.
干预措施: HVLA L3/4 (Other)
Control Group
In each participant, blind assessors will perform pre-intervention measurements of dislocation of center of pressure (CoP), plantar pressure mean and plantar contact area in a baropodometric pressure platform.
Next, the investigator will perform a Sham technique. Then, the same measurements before described will be repeated, by the assessors 1 minute after the intervention.
干预措施: Sham (Other)
结局指标
主要结局
Change from Baseline of center of pressure displacement after intervention
时间窗: Immediately after the intervention
To obtain the center of pressure displacement measurements, it will be used Emed / CL program. This outcome will be measured either in sagittal plane in anteroposterior direction (x-axis) and in frontal plane in medial-lateral direction (y-axis) The participant will be standing in Emed pressure platform in upright position,with relaxed mouth, upper limbs along the body and feet shoulder-width apart, looking to an object standing 1 meter in front of participant´s eyes during 60 seconds. The Emed/ CL program will determine the This procedure will be repeated 3 times. The participant will rest sited on chair during 30 seconds between each measurements evaluation.
次要结局
- Change from Baseline of plantar pressure mean(Immediately after the intervention)
- Change from Baseline of plantar contact area(Immediately after the intervention)
