Claim Text:
1. A measuring device for indicating level of fatigue, the measuring device comprising a cuff with two electrodes, anode and cathode, and a current generator which is arranged to form impulses for electrodes, wherein the cuff is provided in a way that it can be placed on the wrist such that at least one of the electrodes is on the volar side of the hand at the point of the median nerve, and the measuring device further comprises an accelerometer that is provided to produce a signal when the accelerometer detects a movement, and the measuring device further comprises a control arrangement that is provided to guide the current generator to produce impulses and to monitor the signal of the accelerometer, to grow the intensity of the impulses in regard to time, to stop producing impulses, when the signal produced by the accelerometer is detected, to save at least the intensity value of the latest impulse and time ΔT, which is a difference between a time of the signal produced by the accelerometer and a time of the latest impulse, and to calculate a level of fatigue based on at least one of the intensity value of the latest impulse and the time ΔT.
