Box and Block Test (BBT): Measuring Manual Dexterity
The Box and Block Test measures manual dexterity by counting blocks moved in one minute. Therapists use this quick assessment to check hand function in people recovering from stroke or injury.
Box and Block Test (BBT)
The Box and Block Test (BBT) assesses unilateral gross manual dexterity. Patients move wooden blocks over a partition within 60 seconds, helping clinicians evaluate upper limb function. It’s a reliable tool in rehabilitation for stroke and multiple sclerosis to monitor recovery progress.

What is Box and Block Test (BBT)
The Box and Block Test (BBT) is a trusted tool for checking manual dexterity. It helps clinicians measure upper limb function in rehab settings. This kit features a wooden box divided by a partition and includes 150 small wooden cubes. It is built to test how well a patient can grasp and move items quickly. During the assessment, individuals have sixty seconds to move as many blocks as they can from one compartment to the other using just one hand. The final score is simply the total number of blocks transferred, making it easy to track progress over time. Therapists use this test for stroke survivors or people with multiple sclerosis to check gross motor skills. It is quick to set up and provides reliable data on hand function. The straightforward design means it works well in clinics or hospitals to guide daily treatment plans effectively.
The Box and Block Test can be scored using one main approach based on manual speed and accuracy. You simply tally the number of blocks a patient moves from one side of the box to the other within a 60 second window. You must test the dominant hand first, followed by the non dominant side. If a person grabs multiple blocks at once, those do not count towards the final score. Higher totals indicate better gross manual dexterity. Therapists usually compare these raw scores against age specific normative data to identify upper limb impairments or track recovery progress over time.
