Enter the scores for each individual task into the calculator to determine the Dynamic Gait Index.
Dynamic Gait Index Formula
The following formula is used to calculate the Dynamic Gait Index (DGI).
DGI = Σ (i=1 to 8) Si
Variables:
- DGI is the Dynamic Gait Index score
- Si is the score for each individual task (ranging from 0 to 3)
- i is the task number (from 1 to 8)
To calculate the Dynamic Gait Index, sum up the scores for each of the 8 individual tasks. Each task is scored from 0 to 3, with 0 indicating severe impairment and 3 indicating normal ability. The total score can range from 0 to 24, with higher scores indicating better dynamic balance and gait abilities.
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.
How to Calculate Dynamic Gait Index?
The following steps outline how to calculate the Dynamic Gait Index (DGI) using the given formula:
- First, assign a score (Si) for each individual task, ranging from 0 to 3. There are a total of 8 tasks (i=1 to 8).
- Next, calculate the sum (Σ) of all the individual task scores (Si).
- Finally, the result of the calculation will be the Dynamic Gait Index (DGI) score.
Example Problem:
Use the following variables as an example problem to test your knowledge:
Task 1 score (S1) = 2
Task 2 score (S2) = 3
Task 3 score (S3) = 1
Task 4 score (S4) = 0
Task 5 score (S5) = 3
Task 6 score (S6) = 2
Task 7 score (S7) = 1
Task 8 score (S8) = 3
Using the formula DGI = Σ (i=1 to 8) Si, calculate the Dynamic Gait Index (DGI) score.
