A dexterity test is a standardized measure of hand and finger control, used to set a baseline and track rehabilitation progress.<\/p>\n <\/div>\n

Six instruments cover most clinical needs, and the Nine-Hole Peg Test is the most used one in neurological rehabilitation.<\/p>\n <\/div>\n

Scores only mean something against age- and sex-matched norms, so never read a pediatric result against adult tables.<\/p>\n <\/div>\n

Reliability figures vary by population, so cite the study behind any norm or reliability number you quote.<\/p>\n <\/div>\n

Practice management software like Pabau keeps dexterity scores inside the patient record, so progress is easy to chart and share.<\/p>\n <\/div>\n <\/div>\n <\/div>\n \n\n\n

A patient tells you their hand feels clumsy. Grip strength looks fine, the arm moves well, and nothing in the chart explains it. Without a standardized measure, that complaint stays a comment in the file.<\/p>\n\n\n\n

A dexterity test puts a number on speed and control in the hand, scored the same way in every session, by every clinician on your team.<\/p>\n\n\n\n

Running the test is the easy part. The skill sits in picking the right instrument and scoring it against the right norms. Then you write it up so the next clinician can act on it.<\/p>\n\n\n\n

A dexterity test puts a number on hand function<\/h2>\n\n\n\n

A dexterity test<\/strong> is a standardized assessment of controlled hand and finger movement. Some instruments measure gross manual dexterity, the broad reach-and-move actions. Others measure fine motor control, the pinch and manipulation work that fills a patient’s working day.<\/p>\n\n\n\n

Occupational therapists, hand therapists, and neurological rehabilitation teams reach for these tools for four jobs:<\/p>\n\n\n\n

    \n
  1. Setting a baseline before treatment starts<\/li>\n\n\n\n
  2. Tracking progress across a course of therapy<\/li>\n\n\n\n
  3. Supporting return-to-work and pre-employment decisions<\/li>\n\n\n\n
  4. Screening for neurological impairment in the upper limb<\/li>\n<\/ol>\n\n\n\n

    Without a standardized instrument, you are left with subjective observation. That cannot be compared across sessions, clinicians, or settings. <\/p>\n\n\n\n

    The American Occupational Therapy Association<\/a> treats standardized functional assessment as a cornerstone of evidence-based practice. Dexterity tests are among its most used instruments for upper extremity function.<\/p>\n\n\n\n

    That matters commercially as well as clinically. A referrer who receives a number with a norm reference behind it will send you the next patient. Occupational therapy practices<\/a> that report scores consistently also spend less time defending their treatment plans at review.<\/p>\n\n\n\n

    Fine motor and gross motor tests measure different things<\/h2>\n\n\n\n

    Before you choose an instrument, decide which motor domain the referral question sits in. That single decision shapes both the test you pick and the way you read the score.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n

    Fine motor tests<\/strong> target precise finger and pinch movements, close to what a pinch grip test<\/a> isolates at a single joint. Gross motor tests<\/strong> measure broader arm-and-hand coordination instead.<\/p>\n\n\n\n

    A few instruments straddle both domains. The Purdue Pegboard is the clearest example, because its subtests run from single-hand pin placement through to two-handed assembly. That range is why it shows up so often in vocational screening.<\/p>\n\n\n\n

    Six instruments cover almost every clinical situation<\/h2>\n\n\n\n

    Here is the working reference for each instrument: how it runs, how it scores, and where the evidence is strongest.<\/p>\n\n\n\n

    1. Nine-Hole Peg Test (NHPT)<\/h3>\n\n\n\n

    The NHPT is the most used fine motor dexterity test in neurological rehabilitation. The patient places nine pegs into a pegboard, then removes them, as fast as they can. Each hand is tested separately, and the score is completion time in seconds. Lower is better.<\/p>\n\n\n\n

    Normative data exist for adults from 20 to 75 and over, split by sex and hand dominance. The Shirley Ryan AbilityLab<\/a> database is the usual first stop for those values.<\/p>\n\n\n\n

    Reliability depends heavily on the population you are testing. Post-stroke samples report test-retest intraclass correlation coefficients around 0.91 to 0.99, while studies in healthy adults have reported values as low as 0.49. So quote the figure from a study that matches your patient group, rather than a single headline number.<\/p>\n\n\n\n

    2. Purdue Pegboard Test<\/h3>\n\n\n\n

    The Purdue Pegboard runs four subtests: dominant hand, non-dominant hand, both hands together, and an assembly task pairing pins with washers and collars. Each subtest scores the number of pins or assemblies completed in a fixed time window. Those bilateral and assembly scores are what make it the default for assembly and manufacturing roles.<\/p>\n\n\n\n

    3. Box and Block Test (BBT)<\/h3>\n\n\n\n

    The BBT measures gross manual dexterity. The patient moves one-inch wooden blocks over a central partition, from one side of the box to the other, in 60 seconds. The score is the number of blocks transferred. Separate adult and pediatric norms exist, and adult norms must never be applied to a child.<\/p>\n\n\n\n

    4. Grooved Pegboard Test<\/h3>\n\n\n\n

    The Grooved Pegboard uses pegs with a key along one side. Each peg has to be rotated to match a randomly angled slot before it goes in. That rotation adds a visuospatial demand the NHPT does not have, which is why the instrument is popular in neurological work. Both hands are tested, and scoring is time-based.<\/p>\n\n\n\n

    5. Minnesota Manual Dexterity Test (MMDT)<\/h3>\n\n\n\n

    The MMDT uses a board with 60 circular discs. The Placing subtest moves discs from the bin into the board holes as fast as possible. The Turning subtest asks the patient to lift each disc, flip it, and replace it. Both score on time, and both suit vocational settings where arm-and-hand speed is the performance question.<\/p>\n\n\n\n

    6. Functional Dexterity Test (FDT)<\/h3>\n\n\n\n

    The FDT looks at tripod pinch and functional grip. The patient turns a row of pegs using a three-point grip against the clock. Penalties are added for dropped pegs and for grip patterns that break the pattern being tested. The adjusted score therefore reflects technique as well as speed, which is useful after hand surgery.<\/p>\n\n\n\n

    How to administer the test without adding measurement error<\/h2>\n\n\n\n

    Every instrument has its own manual, and the manual wins any argument. A shared pre-test routine still cuts error across all of them, so work through this sequence before you start the clock.<\/p>\n\n\n\n

    Before you start: The six-step setup<\/h3>\n\n\n\n
      \n
    1. Position the patient the same way every time.<\/strong> Seated, both feet flat, testing surface at elbow height. Table height changes reach mechanics, and reach mechanics change the score.<\/li>\n\n\n\n
    2. Check the equipment.<\/strong> Count the pegs, blocks, or discs and look for damage. Lay everything out in the starting position the manual specifies, and replace worn parts before testing.<\/li>\n\n\n\n
    3. Read the script and demonstrate once.<\/strong> Use the manual’s wording rather than your own. Show the task a single time, and give no coaching during the practice attempt.<\/li>\n\n\n\n
    4. Run one practice trial per hand.<\/strong> Keep it untimed. This absorbs the learning effect, so the scored trial reflects ability rather than unfamiliarity.<\/li>\n\n\n\n
    5. Test the dominant hand first.<\/strong> Most protocols specify that order, but check your manual. The Purdue Pegboard uses a fixed right-left sequence instead of a dominance-based one.<\/li>\n\n\n\n
    6. Time it and record it properly.<\/strong> Start the clock on your \u00ab\u00a0go\u00a0\u00bb, not on first contact. Note the raw score, plus any deviation such as a dropped peg or a repeated question.<\/li>\n<\/ol>\n\n\n\n

      Mistakes that invalidate a score<\/h3>\n\n\n\n

      None of the following will make a session feel wrong at the time. Each one, though, makes the number impossible to compare later.<\/p>\n\n\n\n
