The Functional Dexterity Test (FDT)

 

​The Functional Dexterity Test was created and developed by Dorit Aaron,  Aaron & Winthrop are donating all proceeds of the FDT to the American Hand Therapy Foundation (AHTF)

 

The FDT was developed to test dexterity quickly in a busy clinic yet provide information regarding the patient's ability to use the hand for daily tasks requiring a 3-jaw chuck prehension (using fingers and the thumb).

 

It has now been standardized for use with both pediatric and adult populations.

-Test is small, portable and easy to administer.

-Takes less than two minutes to perform.

-Hardwood board measures 8" (21cm) square, and has a locking cover.

-The 16 wooden pegs measure 9/10" (2.2cm) in diameter and 1-6/10" (4.0cm) in length.

-Equipment standards, testing instructions, reliability, validity and normative data based on numerous clinical studies performed over 20 years.

-Test involves turning all the pegs over as quickly as possible using the non-injured hand, followed by a timed test of each hand.“Time Only” score quantifies the speed of hand dexterity and the “Time plus Penalty” score quantifies the quality of the performance.

-Includes a Functional Level Score Sheet based on hand dominance and normal speed performing activities of daily living using a three-jaw chuck prehension pattern.

-Test is now applicable for all ages.
