Upper limb evaluation tool including freeware for the Web

The I-MATCH Upper Limb Evaluation Tool is a set of computer-based tests using Haptic interface, Assistive Technology devices or standard PC equipment as input devices. These tests are used to provide an objective measurement of the performance of the subject's upper limbs. Each test is conducted in a Virtual Reality setting and enables online recording of a set of parameters that are used to assess the user upper limb ability.

The tests include:
- Peg-In-Hole, a test inspired by the Nine Hole Peg Test (NHPT), which is used in clinical assessment. The Peg-in-hole assessment is essentially a 3D task presented in a virtual space. It has a simple geometry and objective. It consists of a large virtual table with two cylindrical holes indented on it, one small cylindrical peg that is to be placed in the holes and alternately moved between them using the hand.
- Circular tracking: tracking a circle clockwise and counter-clockwise
- Linear tracking: the user is required to follow a line to its edge and backwards. The test is repeated in six directions.
- Target tracking: The patient's task is to move toward the target from the current position in the most natural way and then to hit it. When completing the current move, the destination point becomes a starting point and a new destination point is generated somewhere else. This procedure is then repeated ten times in total.
- Labyrinth: In this test, a complex and movement demanding virtual environment, representing a labyrinth and aligned with the person s frontal plane is presented to the patient. The patient can move the pointer, represented with a ball, through the labyrinth in three dimensions. The visual and tactile information is fed back to the person using the computer display and haptic interface (in case one is used). The person can feel all the reactive forces occurring in ball contact with the labyrinth walls and can get the realistic impression as he/she was interacting with the real environment. This test can capture the finger dexterity, the forearm and shoulder movement abilities.
- Maximal force: This task measures the capacity of exerting forces in six evenly distributed directions.

The I-MATCH Haptic Evaluation Tool generates reports, which include a graphical representation of the measured parameters for each test subject. This provides the Technology Providers with immediate visual information about the ability of the test subject.
A cut-down version of the Haptic Evaluation Tool, which does not have the ability to generate reports or log patient data, is freely available on the I-Match website.
