MENENDEZ ALVAREZ, Jaime et al. Experimental electronic system for the measurement of gait parameter variables in elderly people. Rev. cienc. tecnol. [online]. 2020, n.33, pp.1-10. ISSN 1851-7587.

This research, which is carried out in Cuba, is about the monitoring of physical performance indicators on elderly people. The parameters under measurement are affected by the specialist subjectivity who measures the parameters without carefully considering the variability that may exist among them. Developing and evaluating, within a laboratory environment, a low-cost electronic system capable of wirelessly measuring these physical variables, allows the possibility to automatically obtain gear parameters. This system is based on an Inertial Measurement Unit (IMU) that is able to measure not only the linear acceleration and angular speed in the three coordinate axes but also the temperature. At the same time, the system transmits data, via Bluetooth, to a PC where signal processing techniques are implemented. The designed measurement system is evaluated through different proofs which demonstrate a satisfying behavior. The obtained results are also shown when using this system in a dynamic equilibrium test in which the physical variables obtained by the IMU are processed to get the sensor angle inclination.
