The BBT was created originally for adult patients with cerebral palsy, to be a measure of gross dexterity. This test was then validated in patients within the framework of a stroke, a CT, MS and other neurological disorders [5], such as Charcot Marie Tooth disease [14], and also in the elderly [7].
It has recently been evaluated in fibromyalgia [2].
This test was patented in 1957 by Patricia Buehler Holser and Elizabeth Fuchs.
It goes like this: The patient is seated at a table in front of him with a wooden box with 2 compartments of equal size (25 x 15 x 7.5 cm). At the beginning of the test, all coloured wooden cubes (150 in number, 2.5 cm edge) are placed in a compartment. The aim is to move the most cubes possible, cube after cube, from one compartment to another, in 60 seconds, and with one hand.
The examiner is opposite the patient.
The total score is the number of cubes located in the initially empty compartment. [1].
Norms in healthy [9] and healthy adult children were defined. And for adults under 50, the average score is higher than 80, between 50 and 70 years it is between 70 and 80, and for patients older than 70 years it is between 64 and 69 [1].
The total time for performing the test is less than 5 minutes. A complete kit costs about 250-300 Euros.
