1. What is the Dynamic Gait Index?

The Dynamic Gait Index (DGI) is a clinical tool used to assess gait, balance, and fall risk in older adults. It evaluates an individual's ability to modify balance while walking in the presence of external demands.

2. How Does the Calculator Work?

The calculator uses the DGI formula:

Where:

• Sum of Scores — Total points from the 8-item assessment (0-24 points)

Explanation: The DGI consists of 8 tasks scored on a 4-point scale (0-3), with a maximum total score of 24 points. The percentage score indicates the individual's performance level.

3. Importance of DGI Assessment

Details: The DGI is particularly valuable for identifying elderly individuals at risk of falls, assessing functional mobility, and evaluating the effectiveness of balance interventions in clinical settings.

4. Using the Calculator

Tips: Enter the total score from the 8-item DGI assessment. Each item is scored from 0-3, so the total should be between 0-24 points.

5. Frequently Asked Questions (FAQ)

Q1: What do different DGI scores indicate?
A: Scores below 19/24 indicate increased fall risk in community-dwelling older adults. Higher scores represent better dynamic balance during gait.

Q2: What are the 8 tasks assessed in DGI?
A: The assessment includes: gait level surface, change in gait speed, gait with horizontal head turns, gait with vertical head turns, gait and pivot turn, step over obstacle, step around obstacles, and stairs.

Q3: Who should administer the DGI?
A: The assessment should be conducted by trained healthcare professionals such as physical therapists, occupational therapists, or physicians.

Q4: How long does the DGI assessment take?
A: The complete assessment typically takes 15-20 minutes to administer and score.

Q5: Are there any contraindications for DGI testing?
A: The test should not be performed if the individual has severe balance impairments that would make the tasks unsafe without assistance or support.
