What is the BBT protocol for each hand?

• A. Performed with the nondominant hand first
• B. Blocks are 2.5 cm squares
• C. Time limit is 120 seconds per hand
• D. Time limit is 60 seconds per hand and both hands tested

Answer: (D)

In the Box and Block Test, each hand is given a fixed amount of time to perform the task, and both hands are tested to capture differences between hands. Specifically, you move as many blocks as possible in 60 seconds with one hand, then repeat the same 60-second trial with the other hand. This consistent timing and testing of both hands provide a reliable measure of manual dexterity and allow meaningful comparisons between hands. Statements that propose a longer duration (like 120 seconds) or testing only one hand don’t fit the standard procedure, and while block size is part of the setup, the key protocol detail here is the 60-second per hand trials conducted for both hands.
