The test is used to measure the gross manual dexterity of a patient or a person using an upper limb prosthetic device.
[3][4] The test consists of a box with a partition in the middle.
The box is placed on the table with blocks placed on one side of the partition.
[5] The number of displaced blocks is a measure of the gross manual dexterity, where a higher number of displaced blocks indicates better fine motor skill.
The outcome can be compared to reference values from healthy test subjects[2] or from tests performed with a prosthesis,[6] enabling the measurement of progression of gross hand dexterity during rehabilitation.
