Abstract
The simulation of human tremor is important in the development and maintenance of systems used in the diagnosis of movement disorders. The aim of this work is to describe a vibration platform able to perform these tasks. The device consists of PC integrated to a loudspeaker and position and acceleration transducers. The software is developed in LabVIEW environment and manages the reception, analysis and storage of sampled signals. The system is able to provide adequate accelerations (0.35G) and is linear in the range of interest (R=0.99). The influence of mechanical loading was also investigated. The results showed that the developed device is able to keep accelerations similar to that observed in patients with Parkinson disease until 68 g. We concluded that the proposed system could contribute to a more accurate implementation and maintenance of instruments dedicated to the measurement of tremor and, therefore, to improve the diagnoses of tremor disorders.
