Functional Gait Assessment
Availability
Available in the public domain: Functional Gait Assessment
Classification
Supplemental-Highly Recommnded: Sport-Related Concussion (SRC) Persistent/Chronic (3 months and greater post concussion)
 
Supplemental: Sport-Related Concussion (SRC) Subacute (after 72 hours to 3 months)
 
Exploratory: Unruptured Cerebral Aneurysms and Subarachnoid Hemorrhage (SAH)
Short Description of Instrument
The Functional Gate Assessment (FGA) is used to evaluate postural stability during various walking exercises. It is a modification of the Dynamic Gait Index and was developed to improve reliability and decrease the ceiling effect.
 
Normal, fast, slow walking with vertical and horizontal turning of the head; backward walking; stair ascension/descension
 
Walking with eyes closed; walking over obstacles, tandem walking
 
Avoids ceiling effects of Berg Balance and Dynamic Gait Index
 
Cut Score 22/30 to classify falls risk.
Comments/Special Instructions
Requirements: A marked 6-m (20-ft) walkway that is marked with a 30.48-cm (12-in) width
 
It is a 10-item test and can be performed with or without an assistive device.
 
Time to administer: 5–10 minutes
 
Administration mode: paper/pen
Scoring
Each item is scored on a 4 level ordinal scale from 0 – 3, with lower scores indicating greater overall impariment:
 
0 = severe impairment
 
1 = moderate impairment
 
2 = mild impairment
 
3 = normal ambulation
