Simulação e desenvolvimento de um dispositivo giroscópico absorvedor de tremores da Doença de Parkinson.

Abstract

As a result of the hardships faced by people with Parkinson’s disease tremors, the simulation and development of a new device capable of absorbing vibrations on the arm of patients that suffer with this pathology is proposed. Due to the strong collateral effects caused by the drugs and the risks that surgery presents, the need of development of new treatment methods for this disease arose. Thus, the use of a gyroscope come as another alternative method of treatment, since it has a high vibration absorption capability under the right adjustments and it is relatively easy to build. In this paper, an arm prototype was conceptualized and conceived to simulate the disease tremor in a patient, with the frequency tremor at 7 Hz. In a second phase, the gyroscope device was built, experimental and simulation tests were conducted. The results were valued using the five different device configurations, where the largest capacity of vibration absorption was 97,96%, while the lowest absorption was 87,91%, however this device had the lowest weight. Besides these, aluminum and nylon disks were also tested, both with a 50 mm diameter, with these being able to absorb about 96% of the arm amplitude vibration. Hence, the device arises as a new alternative method of Parkinson’s tremor treatment, enabling the execution of simply daily tasks by Parkinson’s patients.
