Clinical Practice and Academic Career

Upon returning from military service, Remak served as an assistant in the department of nervous diseases at the Charité hospital in Berlin from 1873 to 1875. He subsequently established a private practice in the city. His academic career advanced steadily, as he became a privat-docent in 1877 and attained the rank of professor in 1893, maintaining ties to Humboldt-Universität zu Berlin.

Contributions to Neurology

Remak authored over 50 essays for professional medical journals. His scholarly output includes the 1895 publication Grundriss der Elektrodiagnostik und Elektrotherapie für Praktische Aerzte. In collaboration with Edward Flatau, he wrote a study on neuritis and polyneuritis for Carl Nothnagel’s Handbuch der speziellen Pathologie und Therapie. His clinical research led to the identification of the Remak reflex, a response involving the plantar flexion of the first three toes and the knee, which indicates an interruption in spinal cord conducting paths.
