- the document US 2006/047447 Al describes a gauze bandage provided with monitoring components, that wraps the hand of the athlete. This arrangement does not allow for a correct positioning of the sensors, because the gauze bandage needs to be wrapped around the hand of the athlete and a different tensioning of the bandage during the wrapping can lead to completely different positions of the sensors. The athlete must take an excessive cure on positioning the bandage, because an incorrect positioning of the sensor can lead to results that are distorted, even to a great extent.
