a tremor reduction device is disclosed . the tremor reduction device has a mechanical flap having a flap portion arranged to apply pressure on part of an inner arm in order to reduce tremor . the pressure can be manually adjusted by moving a rod in a channel in the tremor reduction device . the tremor reduction device has a case for pivotably mounting the mechanical flap and the pressure is at least partly determined by the angle of the mechanical flap relative to the case . the rod has a tapered section and the mechanical flap has a pin in contact the tapered section for changing the angle of the mechanical flap . optionally a sensor is placed near the pressure applying location to sense the tremor and to provide a sensing signal to a driving mechanism which causes the rod to move in order to adjust the pressure .
