About this study

The wobble board is an unstable equilibrium platform, constant training on this platform generates an improvement in balance and strengthens the muscles, it is ideal for rehabilitation exercises and balance conditioning. However, these platforms do not provide quantitative data on exercises performed on it. And the force platform that provide this quantitative data is static, offering no difficulty in maintaining balance. In this way, a sensor board wobble board was developed using a conventional wobble board with a plate attached to it, between the plate and the platform are eight strain gauges sensors that are activated according to the position of the force applied on the platform, the values of the sensors are collected by software that demonstrates the point of greatest pressure on the disk and its displacement during the exercises, with this data it is possible to determine the stability of the user and observe their behavior during the exercises.

Treatment and study plan

With feedback

Diagnostic Test

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

Without feedback

Diagnostic Test

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

Primary outcomes

  1. 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).

Secondary outcomes

  1. 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).
