Resumo

Introduction: The world population is aging rapidly. A third of those over 65 years of age falls at least once a year, and this prevalence increases by half when they exceed 69 years. Objective: To determine the sensitivity of the use of inertial sensors to determine the gait and rotations of the trunk in a group of healthy individuals. Materials: We use 3 inertial sensors of 9-axis together with the same number of microcontrollers, that sent the information via bluetooth to the computer, the data processing was carried out through an analysis program developed in MATLAB. To analyze the sensitivity of the sensors we use the protocol of Akram et al,5 modified, which consists of 5 activities. Results: In our study 6 volunteers participated, with an average age of 29 years, with an age range 25 to 33 years. The sensors were able to detect multiple variables, including the maximum and minimum elevation of the legs, number of steps, the degree of inclination of the trunk, rotation, speed and cadence. Conclusion: The results obtained are promising and we believe that the use of multiple inertial sensors to assess gait and balance could result in a new tool for the diagnosis and monitoring of people with gait and balance disorder.
