Abstract: This invention refers to a device that reduces and counteracts human motor symptoms (tremor in the upper limbs, muscular stiffness, bradykinesia or slowness in movements, postural disruptions, Parkinsonian walking and freezing in the walking) caused by Parkinson's disease. The device produces vibration by means of a micro-motor that can be modulated in time, speed and power. A laser diode generates a light that is projected in the ground in the form of a horizontal line, a Bluetooth module communicates this device with different intelligent electronic devices and with applications. These components are powered by a rechargeable handheld power source. The components are powered by a rechargeable handheld electric energy source.
