reflex is absent, even in the face of the Jendrassic maneuver, the reflex is consideredabsent.Monofilament Testing: For this examination, it is important that the patient’s foot besupported (i.e., allow the sole of the foot to rest on a flat, warm surface). The filamentshould initially be prestressed (4-6 perpendicular applications to the dorsum of theexaminer’s first finger). The filament is then applied to the dorsum of the great toemidway between the nail fold and the DIP joint. Do not hold the toe directly. Thefilament is applied perpendicularly and briefly, (<1 second) with an even pressure. Whenthe filament bends, the force of 10 grams has been applied. The patient, whose eyes areclosed, is asked to respond yes if he/she feels the filament. Eight correct responses outof 10 applications is considered normal: one to seven correct responses indicates reducedsensation and no correct answers translates into absent sensation.
