Parkinson's disease (PD) is a neurodegenerative disease that occurs due to loss of dopamine, a neurotransmitter and slow destruction of neurons. Brain area affected by progressive destruction of neurons is responsible for controlling movements, rigid gestures of patients with PD, uncontrollable position, postural instability, and tremor. Commercial activity-promoting gaming systems such as the Nintendo Wii™ and Xbox Kinect™ can be used as tools for tremor, gait or other biomedical signals acquisitions, also to aid and in rehabilitation in clinical settings. This paper emphasizes the importance of using intelligent optical sensors or accelerometers in biomedical signal acquisition, and the specific dynamics of nonlinear parameters in parkinsonian gait and tremor analysis
