Design of a Power-Assistive Robust Controller for Parkinson's Tremor in Human

In voluntary oscillatory motion in muscle causes tremor in Human. Parkinson’s Tremor (PT) is one of the most common movement disorders. Without impeding the patient’s intentional motion estimating the tremor suppression in musculoskeletal level is a major challenge. To address this issue, a wearable device is designed for limb tremor could benefit a considerable number of patients, but the technology to suffer in this way is under-developed. In this paper a robust controller that can dynamically suppress pathological tremor with Raspberry-pi board is developed. Electromyogram (EMG) signal parameters are important for assessing muscle activity and fatigue. The start/stop times for each EMG burst are identified by the hand movement. Flexibility of the PT patient’s hand is identified using FlexiForce(flexible) sensor. Then the numerical values are measured and displayed in Raspbian OS with Qt creator. Finally the Simulation results are shown using LabVIEW software.
