Froment’s maneuver

Jules Froment was a pupil of Babinski at la Salpêtrière Hospital in Paris. He discovered that voluntary activity and also resistance against gravity increases rigidity in Parkinson’s disease patients. During the examination of a patient with mild rigidity, repetitive activity with the opposite hand is performed such as making a fist or turning the arm at the shoulder joint like a windmill (“moulinet”). Resulting increased rigidity is described rigidity with activation or rigidity with facilitation. Froment’s maneuver is especially useful in examination of patients with mild Parkinson’s disease. This phenomenon is appreciated worldwide and called Froment-Manöver in German. The original French names are Manœuvre de Froment and test du poignet figé which means stiff wrist test.

For more about Froment, please see an excellent article by Dr. Broussolle in the Movement Disorders Journal.
