Geste Antagoniste Effects on Motor Performance in Dystonia-A Kinematic Study.

ABSTRACT:

Background

The kinematic effects of gestes have not previously been studied. The mechanism(s) by which these sensory tricks modify dystonic movement is not well understood.

Objectives

A kinematic investigation of the geste phenomenon in patients with dystonia.

Methods

Twenty-three patients with dystonia associated with a geste were studied. Twenty-nine healthy controls also participated. Fifteen seconds of finger tapping was recorded by electromagnetic sensors, and the task was repeated with geste. Separable motor components were extracted using a custom-written MATLAB script. Performance with and without geste was compared using Wilcoxon signed ranks testing.

Results

Speed and fluency of finger tapping is impaired in dystonia
