Stereognosis
Stereognosis tests the individual’s ability to perceive and integrate a variety of sensory modalities and to interpret the stimuli to identify small objects placed in the hand.
Expected findings - The individual can successfully identify 90-100% of all objects placed in his/her hand within 2-3 seconds of placement.
Equipment - Several of the following items: paper clips, pens, pencils, coins, erasers, dominos, dice, keys, and cotton balls
Testing procedure
- Explain the procedure to the patient with his/her eyes open. For example, “I will be placing several common items in your hand, one item at a time, and I would like you to identify the item by name.”
- Demonstrate the procedure with the patient’s eyes open until the patient understands the procedure to be performed.
- The patient closes his/her eyes, or vision is otherwise occluded.
- Place objects in the individual’s hand, one object at a time.
- Ask the patient to sufficiently identify the object.
