Dynamic Gait Index - DGI

Original, 8-item test

The modified 4-item DGI uses the first four items of the original DGI:

1. Gait on level surface
2. Gait with speed changes
3. Horizontal head turns
4. Vertical head turns

Maximum score = 12/12

"With regard to the use of the 4-item DGI as a screening tool for falls, the higher specificity of the 4-item DGI suggests that a closer evaluation of fall risk factors is indicated if an individual has a score of less than 10 of 12."
