Functional Gait Assessment (FGA)

How does this Functional Gait Assessment PDF work?

The Functional Gait Assessment PDF is a systematic and comprehensive tool for healthcare professionals to evaluate gait deviations, particularly in older adults. The step-by-step process outlined in the PDF involves a series of tasks designed to assess different aspects of an individual's gait and postural stability.

Beginning the assessment

Individuals are instructed to begin walking at their normal pace to establish a baseline for their typical gait pattern. This allows healthcare professionals to observe and analyze if the individual demonstrates mild gait deviations from the norm.

Walking straight

The PDF guides individuals to walk straight for a designated distance. This task assesses maintaining a normal gait pattern without deviations or imbalance, providing valuable insights into overall gait stability.

Walking backward

Another component involves walking backward, evaluating the individual's ability to navigate in reverse. This task provides insights into dynamic balance, coordination, and the presence of gait deviations in an unconventional direction.

Gait with an assistive device

If applicable, the assessment considers walking with an assistive device. This accounts for individuals who may rely on aids like canes or walkers, providing a more accurate representation of their functional gait in daily life.

Turning and pivoting

The PDF likely includes instructions for turning and pivoting during walking. This assessment of the agility and balance required for changing directions is crucial for understanding an individual's capacity to navigate real-world environments.

Head turns and eyes closed

Tasks involving head turns and walking with eyes closed assess vestibular function and proprioception. These challenges help identify potential gait deviations under altered sensory conditions, enhancing the assessment's sensitivity.

Obstacle negotiation

During the assessment, individuals may encounter obstacles, requiring them to step over objects. This evaluates the ability to adapt gait to environmental challenges, offering insights into dynamic balance control.

Narrow base of support

The PDF likely includes a task where individuals walk with a narrow base of support, emphasizing heel-to-toe alignment. This assessment, which reflects real-world scenarios, assesses balance and stability under challenging conditions.

Scoring

The Functional Gait Assessment template scoring is based on an ordinal scale, providing a systematic way for healthcare professionals to evaluate an individual's gait performance. The template assigns scores ranging from 0 to 3 for different components, with higher scores indicating better gait function.

Typically, scoring goes as follows:

• You give them a three (3) if they can follow instructions quickly, accurately, and without assistance.
• You give them a zero if (0) they can't or refuse to do the movement. 
• You give them two (2) or one (1) depending on how they compensate to accomplish the task. Refer to the template for the specific description differences between the two

For example, in the Gait Level Surface section, a score of 3 is given if the individual walks 20 feet without aids at a good speed and with a normal gait pattern, demonstrating no evidence of imbalance. On the other hand, a score of 0 suggests severe impairment, where the person cannot walk the distance without assistance, displaying severe gait deviations or imbalance.

In the Change in Gait Speed section, a score of 3 is awarded if the individual can smoothly change walking speed without losing balance or gait deviation. Conversely, a score of 0 is given for severe impairment, indicating the inability to change speeds or experiencing a loss of balance.

Similar scoring applies to other sections, such as Gait with Horizontal Head Turns, Gait with Vertical Head Turns, and Steps, where the individual's ability to perform tasks with minimal disruptions to the gait path is assessed.

The scoring system is integral in providing a quantitative measure of gait function, allowing healthcare professionals to identify specific areas of impairment. Using an ordinal scale simplifies the interpretation, making it an effective tool for evaluating gait deviations in older adults.

The scores obtained from each section can be totaled to provide an overall assessment of an individual's functional gait, aiding in classifying fall risk and informing targeted interventions, monitoring gait changes to see if there are significant gait deviations, assess the effectiveness of assistive devices in maintaining a smooth gait path.
