Tremor reduction device

Abstract

A wearable tremor reduction device reduces tremor by internally generating forces which cancel or reduce the magnitude force of the tremor experienced by the person wearing the device. The device maybe worn on a wrist, arm, ankle or leg. The device has a plurality of housing members which are flexibly connected together. Each housing member contains a mass which is translatable along an axis between a proximal limit and a distal limit, and a neutral position midway between the proximal limit and the distal limit. Following imposition of a force having a component along the axis, a biasing means returns the mass to the neutral position.

Description

Background technique [0001] Tremors of various extremities in the human body are common movement disorders characterized by rhythmic oscillations of the limb around one or more joints. One of the most important characteristics to be evaluated in a patient's tremor is tremor frequency, which is measured in oscillations per second or cycles per second (Hz). Another important characteristic of tremor is amplitude, which is the linear or angular displacement of a limb or body part. Tremor amplitude is measured in millimeters or degrees. Tremor frequency and amplitude can be measured with relatively high accuracy by known devices and methods. [0002] Tremors caused by Parkinson's disease (ie, parkinsonian tremor) and essential tremor can significantly affect the quality of life of people with these diseases. Everyday functions that are often taken for granted by people without tremors (such as eating, brushing hair, brushing teeth, etc.) can be demanding and frustrating movemen...
