An Instrumented Wobble Board to Present the Distribution and Center of Pressure in Dynamic Balance

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

Study Overview

• Status: Completed
• Conditions: Balancing Interference
• Intervention / Treatment: Diagnostic test: With feedback; Diagnostic test: Without feedback

Detailed Description

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.

Intervention / Treatment

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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 Outcome Measures

Outcome Measure	Measure Description	Time Frame
Longest distance between points on X and Y axis	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).	15 minutes
