The MDF Trömner Hammer (aka Tromner or Troemner) is a versatile 3-in-1 dual
mallet-type reflex hammer designed for eliciting myotatic and cutaneous
responses in adult and pediatric patients. This popular reflex hammer was
invented by Ernst L.O. Trömner, MD, a director of the Neurological Hospital at
St. George and professor at the University of Hamburg.
The balance-weighted stainless-steel head is outfitted with large and small
mallets constructed of soft silicone for precise percussions.
The weighted stainless-steel handle is precisely balanced for increased
control of force for percussion. The tip at the base of the handle elicits
superficial or cutaneous responses, including plantar and abdominal
