- ItemROSENBLUETH PHENOMENON(1979) BEHRENS, MI; LORENZO, D; FERNANDEZ, O; LUCO, JVRosenblueth and Luco (1939) showed that, during prolonged stimulation of a motor nerve, neuromuscular fatigue is followed by a rise of tension that has been called the Rosenblueth Phenomenon. The Rosenblueth Phenomenon was investigated in a cat neuromuscular preparation in which the nerves were severed at different levels and stimulated at 60 Hz for several hours. In the longer nerve preparation the Rosenblueth Phenomenon starts earlier and its maximal tension is higher. Acetylcholine sensitivity was studied in the superior cervical ganglion preparation and no change was observed when tested before stimulation, during fatigue and during the Rosenblueth Phenomenon. The onset and amplitude of the Rosenblueth Phenomenon depend on the length of the peripheral nerve stump: the longer the stump, the earlier and higher the response. The Rosenblueth Phenomenon is apparently produced by an increase in the transmitter release which would be due to axonal progression of molecules along the nerve.
