| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Performance-based instrument |
| Brief Description |
The GAT is an instrument developed for measuring hand function in patients with RA.The GAT includes the following three practical tasks: putting a flexigrip stocking over the nondominant hand, putting a paper clip on an envelope, and pouring water from a jug. The GAT is a performance-based test. |

| PRACTICAL APPLICATION | |
| Method of administration | Physician |
| Recommendations to score |
The sum of the weighted time (in seconds) used for the performance of each task is scored. |
| Score Interpretation | A high GAT score is a sign of decreased hand function |
