A rare Italian Algesimetro by Dott. Belloni

Categories: Medicine, Other Medical Antiques


A very rare “Algesimetro”, a specialistic medical instrument developed by Dott. Cesare Belloni for his pioneering research on the human pain in the early 1900’s.

Dott. Cesare Belloni was a Medical Director of the Insane Asylum in Genova, around 1910’s, and his study involved 132 nurses (64 man and 68 women) plus an undefined number of patients of the asylum to “measure” the pain sensitivity of the different parts of the human body, under different condition, with a comparison man/woman, etc…

The results were published with the title “Ricerche algesimetriche sulla cute dell’uomo e confronti fra i due sessi”, in 1920 in the “Archivio di antropologia criminale, psichiatria e medicina legale”.

The instrument was specifically designed by Dr. Belloni, a needle at the tip is connected to a mechanism that registers the pressure (it’d require a bit of lubrication to recover its sensitivity).

Dr. Belloni claimed that when the pressure overcomes 130 gr (enough for the purpose of the test) the sharp point totally entr inside the tool avoiding any injury.

Measurements of the case: 18,5 x 8 x 1,5 cm
