Dynamic Gait Index Calculator

Formula

The formula to calculate the Dynamic Gait Index is:

\[ \text{DGI} = \sum_{i=1}^{8} S_i \]

Where:

\( \text{DGI} \) is the Dynamic Gait Index score
\( S_i \) is the score for each individual task (ranging from 0 to 3)
\( i \) is the task number (from 1 to 8)

What is a Dynamic Gait Index?

The Dynamic Gait Index (DGI) is a physical therapy assessment tool used to evaluate a person's ability to modify balance while walking in the presence of external demands. It measures the individual's gait, or manner of walking, under various conditions, including changing speed, turning the head, stepping over and around obstacles, and climbing stairs. The DGI is often used to assess individuals with balance or vestibular disorders, and can help determine fall risk and guide treatment planning.

Example Calculation

Let's consider an example:

Task 1 Score: 3
Task 2 Score: 2
Task 3 Score: 3
Task 4 Score: 2
Task 5 Score: 3
Task 6 Score: 2
Task 7 Score: 3
Task 8 Score: 2

Using the formula to calculate the Dynamic Gait Index:

\[ \text{DGI} = 3 + 2 + 3 + 2 + 3 + 2 + 3 + 2 = 20 \]

This demonstrates that with the given scores for each task, the Dynamic Gait Index is 20. ✅
