PARKINSON’S DISEASE ANALYTICS: SENSING AND ANALYSIS OF VIBRATIONS OF TREMOR

Abstract

Parkinson's disease (PD) is a chronic progressive neurodegenerative movement disorder characterized by a profound and selective loss of nigrostriatal dopaminergic neurons. Clinical manifestations of this complex disease include motor impairments involving resting tremor, bradykinesia, postural instability, gain difficulty and rigidity. Current medications only provide symptomatic relief and fail to halt the death of dopaminergic neurons.The main aim of this paper is to analyse the exact frequency of the tremor using cheaper and more cost-effective methods and also to reduce the frequency using gyrostabilizer. Accelerometer and flex sensor is used to precisely measure the hand vibration caused due to tremor. Hand tremor is controlled using gyrostabilizer containing high speed rotating disc which is driven by a dc motor. The rotating disc follows the law of conservation of angular momentum so as to maintain its natural position thus dampening the vibrations caused by the tremor.
