Abstract: The tendon depressor is a tool that is designed to be used while eliciting deep tendon reflexes. A first embodiment of the depressor may be worn on a user's thumb, while the second embodiment may be worn on an index finger. Each embodiment includes a top portion made out of rigid plastic, with a thin layer of soft sponge being provided on a bottom surface of the plastic. A thin, elastic rubber material is connected beneath the sponge portion and serves to receive the user's thumb or finger. The tendon depressor is designed to create a more comfortable and accurate clinical procedure to elicit certain tendon reflexes, such as the biceps brachii, biceps femoris, semitendinosus, semimembranosus, pectoralis and suprapatellar reflexes.
