Box & Blocks

The Box and Block Test (BBT) is a functional test used in upper limb rehabilitation. The test is used to measure the gross manual dexterity of the patient, or of a person using an upper limb prosthetic device. It can be used with patients with a range of neurological diagnoses, including, Strokes, Multiple Sclerosis, Traumatic Brain Injury, Neuromuscular Disorders, Geriatric, Spinal Cord Injury, Fibromyalgia. Otherwise, this test cannot be used with patients who have severe upper extremity impairment or those with severe cognitive impairment.

The BBT is composed of a wooden box divided into two compartments by partitions and 150  blocks. The BBT administration consists of asking the client to move, one by one, the maximum number of blocks from one compartment of a box to another of equal size, within 60 seconds. The box should be oriented lengthwise and placed at the patient's midline, with the compartment holding the blocks oriented towards the hand being tests. In order to practice and register baseline scores, the test should begin with the unaffected upper limb. Additionally, a 15-seconds trial period is permitted at the beginning of each side. Before the trial, after the standardized instructions are given to the patients, they should be advised that their fingertips must cross the partition when transferring the blocks and that they do not need to pick up the blocks that might fall outside of the box.

This application offers an alternative way to perform the test, using only a computer and a LeapMotion device.
