Experimental: Volunteers without motor abnormalities.
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
To evaluate the displacement of the center of pressure on the disc during the equilibration with feedback.
Diagnostic Test: Without feedback
To evaluate the displacement of the center of pressure on the disc during the equilibration without feedback.
- Pressure center displacement speed [ Time Frame: 15 minutes ]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).
- Longest distance between points on X and Y axis [ Time Frame: 15 minutes ]It was measured at the greatest distance of the center of pressure displacement on the X and Y axis during the test, divided into two steps, with three repetitions at each stage, with a rest of 30 seconds at each repetition. Unit of measurement: Centimeters (cm).
