Mobility Assessment Tool: Short Form


The Mobility Assessment Tool (MAT) is a video-animated tool for assessing self-perception of mobility. Items in the MAT consist of a video and a corresponding measurement item. The videos depict a wooden mannequin performing a wide range of physical activities, and the measurement item consists of a question about the participant’s ability to perform the task, measured on a discrete scale.

The software applications presented here are short forms of the original 81-item instrument described in[1] and [2]. The 10-item instrument is the first short form MAT that was developed. The 12-item instrument includes the 10 items in the 10-item instrument as well as 2 additional items that help to capture a broader range of mobility.


The only requirement for the MAT-sf software to run correctly is Java 7 or newer.

Please note: Depending on the speed of your computer, it may take up to a minute between attempting to run the MAT-sf program and the program appearing.


Download the version of the test application that is best suited for your computer. Please be sure that Java 7 or newer is installed on your computer.
