Welcome to the Functional Gait Assessment (FGA) Calculator. This tool is designed to help clinicians and individuals quickly calculate the FGA score, a valuable measure for assessing gait, balance, and fall risk in various populations. Below, you'll find the calculator followed by a comprehensive guide to understanding and utilizing the FGA.
Functional Gait Assessment (FGA) Score

Understanding the Functional Gait Assessment (FGA)
The Functional Gait Assessment (FGA) is a 10-item clinical balance and gait assessment tool developed as a modification of the original Gait Abnormality Rating Scale (GARS). It is primarily used to assess postural stability during various walking tasks and predict fall risk in older adults and individuals with neurological conditions.
Purpose and Applications
The FGA is a highly regarded tool for several reasons:
- Fall Risk Prediction: It helps identify individuals at a higher risk of falling, allowing for timely interventions.
- Balance and Gait Assessment: It evaluates an individual's ability to perform various functional walking tasks, including changes in speed, head turns, and navigating obstacles.
- Tracking Progress: Clinicians use the FGA to monitor changes in a patient's balance and gait over time, assessing the effectiveness of rehabilitation programs.
- Neurological Conditions: It's particularly useful for patients with conditions such as Parkinson's disease, stroke, multiple sclerosis, and vestibular disorders.
How the FGA is Administered
The FGA consists of 10 tasks, each scored on a 4-point ordinal scale (0-3), with a maximum total score of 30. A score of 3 indicates normal performance, while 0 indicates severe impairment or inability to perform the task. The tasks include:
- Gait on Level Surface
- Change in Gait Speed (slow to fast)
- Gait with Horizontal Head Turns
- Gait with Vertical Head Turns
- Gait with Pivot Turn (180 degrees)
- Step Over Obstacle (shoebox height)
- Gait with Narrow Base of Support (tandem gait)
- Gait with Eyes Closed
- Backwards Gait
- Walking Up and Down Stairs
Standardized instructions are provided for each task to ensure consistency in administration.
Interpreting Your FGA Score
The total FGA score ranges from 0 to 30. A higher score indicates better functional gait ability and lower fall risk.
- Scores below 22/30: Generally indicate an increased risk of falls in community-dwelling older adults.
- Scores below 20/30: Often used as a cutoff for increased fall risk in individuals with vestibular disorders.
- Scores below 15/30: May suggest significant gait and balance impairments requiring substantial intervention.
- Scores of 30/30: Represent excellent functional gait.
It's important to note that specific cutoff scores can vary slightly depending on the population being studied and the clinical context. Always consult with a healthcare professional for a personalized interpretation of your score.
Limitations
While the FGA is a robust tool, it has some limitations:
- It requires a trained clinician to administer accurately.
- It may not capture all aspects of complex gait abnormalities.
- Environmental factors (e.g., lighting, surface) can influence performance.
