Abstract: A wrist signal means in the form of a wrist wrap to encircle the wrist of a user and in which there is a pocket extending across the back of the hand and the forearm at the wrist juncture so that, when the wrist is moved in flexion or extension, a flat generally rectangular metal plate in the pocket is flexed or bent causing a noise to be emitted to signal that the wrist has been moved. The device may include a tightener strap to tighten the noise-making plate against the wrist.
