[Relaxograph--an improved technic for measuring relaxation]

The Relaxograph offers a facile measurement technique for relaxation. Electromyographic registration allows this technique to be used even in extreme positioning of the patient. Placement of the electrodes, calibration and measurement can be learned and applied in a very short time. Simple operation enables immediate and undisturbed working with this measurement system which is ideally suited for clinical routine. The problems encountered with the predecessors of this series in respect of calibration and measurement on the previously relaxed patient, have been largely done away with by this new concept.
