Brief Summary

This study quantified the displacement of the center of pressure in the computer in real time and record this data for future analyzes

Conditions

Balancing Interference

Keywords

Wobble board; center of pressure; dynamic balance; force platform

Outcome Measures

Primary Outcomes (1)

• Pressure center displacement speed

  The velocity at which the center of pressure moves during the test, divided into two steps, with three repetitions at each step, with a rest of 30 seconds at each repetition, was measured. Unit of measure: Centimeters per second (cm / s).

  15 minutes

Secondary Outcomes (1)

• Longest distance between points on X and Y axis

  15 minutes

Study Arms (1)

Volunteers without motor abnormalities.

EXPERIMENTAL

The test was performed in a single, 30-minute session. The test is divided into two phases, with feedback and no feedback from the system. The order of phases was randomized. In each phase the volunteer will remain balanced on the wobble board for 15 seconds under the conditions of the phase. This test is repeated 3 times with a 30 seconds rest between them, then the next phase is performed. With feedback the volunteer can observe the system responses. Without feedback the volunteer can not observe the response of the system.

Diagnostic Test: With feedback; Diagnostic Test: Without feedback

Interventions

With feedback DIAGNOSTIC_TEST

To evaluate the displacement of the center of pressure on the disc during the equilibration with feedback.

Volunteers without motor abnormalities.

Without feedback DIAGNOSTIC_TEST

To evaluate the displacement of the center of pressure on the disc during the equilibration without feedback.

Volunteers without motor abnormalities.
