Jules Froment earned his doctorate in 1906, producing a thesis focused on heart diseases linked to thyrotoxicosis. This work established his path as a French neurologist, a career primarily conducted in his home city of Lyon. His professional life spanned the early twentieth century, concluding with his death in the 7th arrondissement of Lyon in 1946.
Wartime Neurology and Collaboration
During World War I, Froment served in Rennes, focusing on the treatment of soldiers suffering from nervous disorders. Following this service, he entered into a significant collaboration with Joseph Babiński. Together, they explored the etiology of conditions frequently diagnosed at the time as combat hysteria or shell shock. Their investigation culminated in the 1917 publication, Hystérie, pithiatisme et troubles nerveux d'ordre réflexe en neurologie de guerre. This research prompted debate within the medical community due to the controversial nature of their findings regarding reflex-based nervous disorders.

Froment and Babiński identified a specific medical condition characterized by muscle atrophy, tissue damage, and various vasomotor disturbances. This observation is recognized today as Babinski-Froment syndrome. Beyond this syndromic research, Froment developed clinical techniques for identifying nerve dysfunction. His primary contribution in this area remains the test for ulnar nerve weakness, commonly termed Froment's sign. By observing a patient attempting to hold a sheet of paper between their index finger and thumb, a clinician can identify ulnar nerve palsy if the thumb flexes involuntarily. This test provides a functional assessment of the adductor pollicis muscle.
Publications and Academic Legacy
Throughout his tenure as a professor at Lyon, Froment contributed regularly to medical literature. His published works include the 1915 article, La préhension dans les paralysies du nerf cubital et le signe du pouce, published in La presse médicale. Later in his career, he explored genetic components of disease, as evidenced by his 1937 work, Heredodegenerations retinienne et spino-cerebeleuse, which detailed ophthalmoscopic and neurological variants observed across three successive generations. These publications reflect the breadth of his clinical research beyond his initial work on thyroid-related cardiac issues.

Questions readers ask
What does Froment's sign measure?
It assesses the integrity of the ulnar nerve by testing the function of the adductor pollicis muscle in the hand.
Did Jules Froment work alone?
Much of his research on reflex nervous disorders and his eponymous syndrome was conducted in collaboration with Joseph Babiński.
