Modified DGI (mDGI):
Expanded Scoring System for the original 8-item test.
(includes time, assistance level, and gait

the Scoring System for the Dynamic Gait Index. Phys Ther. 93:1493-1506.
"The 95% minimal
detectable change was 4 for the mDGI total score."
The 4-item DGI uses the first four items of the original DGI:
on level surface
2. Gait with speed changes
3. Horizontal head turns
4. Vertical head turns
score = 12/12
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."
