## Indications for use
The NeuroTrace III can be used as an objective monitor using accelerometry for measuring the muscle contraction following stimulation of the respective motor neuron, as a peripheral nerve stimulator (without the objective measuring function) for subjective monitoring and for locating specific nerves. It is particularly useful in nerve block procedures to obtain effective regional anesthesia blocks.
