Hand Tremor Prediction
and Classifcation Using
Electromyogram Signals to
Control Neuro-Motor Instability
ABSTRACT
This chapter provides a prototype design of a hand tremor compensator/controller to reduce the effect
of the tremor to an external device/ apparatus, such as a magnetic pen for the patients suffering from
Parkinson and similar diseases. It would also be effective for busy surgeons suffering from hand tremor
due to muscle fatigue. Main emphasis in this chapter is given on the prediction of the tremor signal from
the discrete samples of electromyogram data and tremor. The predicted signal is inverted in sign and
added to the main tremor signal through a specially designed magnetic actuator carrying the external
device, such as a magnetically driven pen or surgical instrument. Two different prediction algorithms,
one based on neural nets and the other based on Kalman Filter have been designed, tested, and validated
for the proposed application. A prototype model of the complete system was developed on an embed-
ded platform. Further development on the basic model would be appropriate for feld applications in
controlling tremors of the subjects suffering from Parkinson and the like diseases.
