Functional Gait Assessment
Available in the public domain: Functional Gait Assessment
NeuroRehab Supplemental - Highly Recommended:
Recommendations for Use: Indicated for studies requiring a measure of motor function. Recommended for Sport-Related Concussion (SRC) studies.
Supplemental-Highly Recommended: 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 Gait Assessment 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
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
