Dynamic Gait Index Calculator
The Dynamic Gait Index Calculator estimates functional gait stability based on performance across 8 critical mobility tasks like walking, turning, and stair climbing. This tool helps physical therapists and clinicians quickly assess fall risk and determine the severity of mobility impairment. Whether you are evaluating balance after a stroke, tracking rehabilitation progress, or screening elderly patients, this tool provides clear, standardized results.
How DGI Score Is Calculated
The Dynamic Gait Index (DGI) score quantifies a patient's ability to maintain balance while performing various motor tasks. To calculate the total, a clinician scores the patient on 8 functional activities, such as walking with head turns or stepping over obstacles.
Each task receives a score between 0 and 3, where 3 indicates normal performance and 0 indicates severe impairment. The individual task scores are then summed to create a total score out of 24.
This summation method highlights specific areas of instability, making it easier to tailor rehabilitation plans. The standardized scoring ensures high inter-rater reliability among medical professionals.
What Your DGI Score Means
Your total score provides a clear category for the patient's mobility and risk of falling. The ranges below help determine the appropriate level of intervention.
| Score Range | Impairment Level |
|---|---|
| 19 - 24 | Normal Gait |
| 14 - 18 | Mild Impairment |
| 9 - 13 | Moderate Impairment |
| 0 - 8 | Severe Impairment |
Patients scoring between **19 and 24** demonstrate normal gait and are generally safe for independent community ambulation. A score of **14 to 18** suggests mild impairment, meaning patients should be monitored for safety, especially on uneven surfaces. Scores in the **9 to 13** range indicate moderate impairment, often necessitating the use of an assistive device like a cane. A score of **0 to 8** signals severe impairment, suggesting the patient is at a very high risk of falling and requires constant supervision.
