Stereognosis: How to Make a Test Kit

Stereognosis: How to Make a Test Kit

We are digging into the who, what, when, where and why of stereognosis in occupational therapy and how to create a kit for your clinic.

Stereognosis is for the person WHO has ever experienced not being able to find their alarm clock on their bedside table in the dark of the morning.

Stereognosis is WHAT is attempting to occur when you try to feel around to shut off the alarm without turning on the light to see.

Stereognosis ponders the scenario – Imagine you are driving in your car, stereognosis is WHEN you can stick your hand into your glovebox, use your touch perception, and successfully find your sunglasses without taking your eyes off the road. This is also referred to as a community mobility safety win!

Stereognosis is the WHERE and WHY does your ability to discriminate between objects without looking even matter?

In Part 1 of this 2-part article series we will get into the “who”, “what”, “when”, “where”, and “why” about stereognosis and what it has to do with occupational therapy and adults. Part 2 will go over the “how” to incorporate stereognosis tests into your OT screenings and evaluation. Then in Part 3 of the series, we will dive into “how” to down grade and up grade stereognosis activities and interventions!

WHO can be affected?

People who have had recent sensory changes may have new difficulties in all of those above-mentioned scenarios. Know that stereognosis deficits can present in people throughout the lifespan; for this article, however, we will focus on adults.

  • Your grandmother who has macular degeneration who has stopped putting on her favorite pink “rouge” because she can no longer see the label and has trouble feeling for the lipstick tube in her full drawer of makeup…
  • A great uncle who is recovering from residual changes from a TIA of a few months ago who has greater difficulty managing to tie his bowtie due to inability to feel for the loophole…
  • The secretary of your OT program who resorts to her dumping out the contents of her lap desk bag out onto a table because she takes longer to feel around for her favorite pen…

WHAT exactly is stereognosis?

  • Stereognosis is a higher cerebral associative cortical function
  • Stereognosis involves using your touch perception and tactile discrimination skills to recognize an item or group of items hidden from your view
  • Stereognosis is the ability to identify items using tactile information
  • Stereognosis is a function of the parietal lobe (where sensory information is processed)

WHEN does occupational therapy have a role?

Occupational therapy practitioners have a role in stereognosis screening and intervention implementation when there is a change. Occupational therapists should create the habit to incorporate stereognosis testing into our sensory assessment portion on an individualized patient to patient basis. We should listen to what our patient or their family members report and if warranted upon assessment results, then interventions that target stereognosis deficits are appropriate to be incorporated in addressing multiple purpose skills with the hopes of improvement for overall performance areas such as in the areas of improved ADL or IADL independence.

WHERE do we get supplies for stereognosis assessment and activities?

Gather supplies for stereognosis assessment and intervention therapeutic activities by shopping around in your clinic, in the hospital, or in your home without spending any money. Supplies can also be purchased at your local dollar store, tool store, or pharmacy.

Where you retrieve your items does not matter as much as it matters to make sure that your items will not cause harm to your patient

i.e. If your patient is very impulsive with poor safety awareness use extreme clinical judgment to determine level of appropriateness.

Questions to ask self: Will my patient try to put an object in his/her mouth to swallow?

Is my patient at risk for cutting self if he/she feels for the plastic spoon or clips?

Another rule of thumb is to be sure to abide by all policies for cleanliness such as wiping down objects with purple tops between patients or replacing objects after one use such as in the case of Qtips or cotton balls…

WHY does Occupational Therapy have a seat at the Stereognosis Table?

  • Scenario Rationale: When you unbutton your pants do you realize that you are feeling for the button and differentiating it from the buttonhole? Or after you complete going to the restroom and hurriedly zip your pants, do you notice that you feel for the zipper tie to pull up the zipper? Do you notice how quickly you can feel, zip, and pull? What if that skill was taken away from you? Think about how that personal occupation (activity that is meaningful or necessary to do for life) of toileting and dressing could drastically change.—That is why OT plays a role in stereognosis assessment, interventions, and outcomes.
  • Short answer: Maximize Task Automatics During Occupations
  • Long answer: Deficits in stereognosis can prevent a patient from easily and “automatically” complete personal tasks related to components of Activities of Daily Living (ADLs) such as dressing; therefore, we as occupational therapy practitioners should try to assess and address this skill in our practice. Additionally, other components that can be combined into stereognosis activities include memory, sequencing, and item categorization among others. Occupational therapy can also address the speed and “automacy” of the task to promote improved engagement and performance in multiple different occupations.

Stay tuned for Part 2 (and Part 3!). This will provide the nitty gritty “how to” assess and screen for possible stereognosis deficits as well as provide the “how to” grade down and grade up therapeutic activities as tailored interventions.
