Development of the Functional Dexterity Test (FDT): construction, validity, reliability, and normative data.
Dexterity tests take time to administer; however, the information obtained is an important component of a comprehensive examination of the hand. This article introduces a dexterity test suitable for use as part of routine examination of the hand. The Functional Dexterity Test (FDT) was developed as a measure of dexterity that takes a minimum amount of time to administer, yet provides information regarding the patient's ability to use the hand for daily tasks requiring a 3-jaw chuck prehension between the fingers and the thumb. The test was developed over 20 years. Interrater and intrarater reliability ranges between good and excellent. Construct validity was confirmed in 2 clinical studies. Preliminary normative data were obtained in 6 samples of convenience. Along with statistical data, this article provides equipment standards and instructions.
