New York: Researchers have developed a novel device that detects neuro-degenerative diseases such as Alzheimer`s and Parkinson`s by recording signals from a patient`s hand muscles during handwriting. Detecting a nuero-degenerative disorder that attacks the central nervous system, causing tremors, rigidity, slowness of movement and loss of balance can be difficult, especially in early stages, researchers said. They said that motor neurons transmit electrical signals to muscles to make them contract.In the new detection system, a test subject attaches Electromyography (EMG) surface electrodes to his or her hand and wears a glove to hold the electrodes in place.
