Emory Functional Ambulation Profile

Abstract

The Emory Functional Ambulation Profile (EFAP) is a validated, standardized physical performance test developed specifically to quantify the walking speed and functional ambulation capabilities of patients following a CVA (Cerebrovascular Accident). The EFAP evaluates diverse aspects of mobility across five distinct tasks, which simulate daily activities. These tasks include walking across varying surfaces, maneuvering around obstacles, and climbing stairs. Assessment involves timing the completion of these tasks and observing the qualitative manner of walking. The EFAP also provides crucial documentation regarding the patient’s reliance on and use of assistive walking devices throughout the evaluation process.

Purpose

The primary purpose of the Emory Functional Ambulation Profile is to provide a quantitative, objective measure of functional mobility in clinical and research settings. By breaking down the walking assessment into five ecologically relevant components, the EFAP allows clinicians to identify specific deficits in ambulation that may be masked by simpler gait speed tests.

It is widely utilized in rehabilitation settings to track functional recovery following a neurological event, such as a CVA. The scores aid in establishing baseline function, monitoring the effectiveness of therapeutic interventions, and assisting in discharge planning by providing a clear profile of the patient’s independence in mobility tasks.

Construct

The EFAP measures the construct of Functional Ambulation Capacity. This construct encompasses the integration of motor control, balance, and endurance necessary for safe and efficient movement within a typical community or home environment. Unlike basic gait speed tests, the EFAP requires dynamic changes in direction, elevation, and surface texture, thus capturing a more comprehensive view of applied mobility.

The test is focused heavily on the functional capacity of the lower extremity and the patient’s ability to adapt their walking pattern to environmental demands, often providing insight into compensatory strategies used by individuals with hemiparesis.

Validity

The EFAP has demonstrated strong concurrent validity, correlating highly with other established measures of balance and mobility, such as the Berg Balance Scale and the Timed Up and Go Test. Its ability to discriminate between different levels of functional independence post-stroke highlights its clinical utility.

Additionally, the scale possesses good predictive validity, as scores obtained upon admission to rehabilitation are often predictive of eventual discharge status and community ambulation potential. It is sensitive to change over time, making it a robust outcome measure for tracking rehabilitation progress.

Reliability

Research indicates that the EFAP exhibits high inter-rater and intra-rater reliability, particularly when the assessors are trained physical therapy professionals adhering strictly to the standardized protocol. The reliance on objective timing, coupled with structured observation by two therapists, minimizes measurement error.

The specific scoring protocol, which simultaneously records time and documents the use of assistive devices, contributes to the overall consistency and dependability of the instrument in repeated measurements across different clinical settings.

Factor Analysis

While the EFAP is often utilized as a single profile reflecting overall functional ambulation, the five distinct components inherently reflect different functional demands (e.g., speed vs. obstacle negotiation vs. elevation change). Preliminary analyses suggest that these components load onto a primary factor representing general mobility performance. Clinically, however, separating the scores for each component is often more useful for targeted therapeutic intervention than relying solely on a composite score.

Instrument

Test Type: Performance-based, Observational

Format: Structured physical tasks requiring timing and qualitative assessment

Language Available: Primarily English (Original development)

Population Group: Clinical Populations

Age Group: Adults and Elderly

Population Details: Individuals suffering from neurological impairments, primarily those recovering from a CVA (Stroke), affecting the lower extremity and mobility.

Test Methodology: The patient performs five standardized tasks while two therapists simultaneously record the time taken and observe the quality of movement and use of assistive devices. The final profile indicates both speed and dependence level.

Permissions & Fee and Test Year

The Emory Functional Ambulation Profile (EFAP) was developed by Nelson AJ in 1979. As a standardized performance measure widely used in clinical practice and research, the core instrument itself is generally available for professional use, though specific administrative manuals or scoring sheets might require authorization from the copyright holder or distribution entity.

Items of the Emory Functional Ambulation Profile

IMPORTANT: The following scale items must be preserved in their original language and must not be changed in any way.

The EFAP consists of 5 components:

1. 5 meter lopen over vloer en tapijt (5 meters walking over floor and carpet)
2. Een “up & go” test (A “Timed Up & Go” test)
3. Afleggen van parcours met obstakels (Completing a course with obstacles)
4. Trap lopen (Stair climbing)

Note: The original source listed 5 parts but only specified 4 distinct tasks, implying the first item (5 meter lopen) consists of two distinct sub-environments (vloer and tapijt) which are timed separately, resulting in five measured segments overall.
