Guide to AFO Brace Selection
AFO brace selection guide to help patients/parents determine their child gait pattern and match their need for available braces.
Mild
Visible medial arch
Mild heel eversion and forefoot abduction
Can correct when prompted
Can be manually corrected with no resistance
Moderate
Reduced medial arch
Moderate heel eversion and forefoot abduction
Can improve when prompted
Can be manually corrected with mild resistance
Strong
Absent medial arch
Strong heel eversion and forefoot abduction
Cannot improve when prompted
Can be manually corrected with moderate resistance
LOW TONE PRONATION
Foot collapses and medial arch flattens
Heel everts
Forefoot abducts
Low muscle tone allows for easy correction
Mild
Visible medial arch
Mild heel eversion and forefoot abduction
Can correct when prompted
Can be manually corrected with no resistance
Moderate
Reduced medial arch
Moderate heel eversion and forefoot abduction
Can improve when prompted
Can be manually corrected with mild resistance
Strong
Absent medial arch
Strong heel eversion and forefoot abduction
Cannot improve when prompted
Can be manually corrected with moderate resistance
High Tone Pronation or Supination
Pronation:
Foot collapses and medial arch flattens
Heel everts and forefoot abducts
Supination:
Foot bears weight on lateral side, high medial arch
Heel inverts and forefoot adducts
Mild
Lands heel first
No obvious compensations of the knee and hip
Occurs almost never (less than 80% of the time)
Can control when prompted
Moderate
Lands foot-flat, accompanied by pronation/supination
Some compensations of the knee and hip
Occurs almost always (80% of the time)
Can improve when prompted
Strong
Lands forefoot-first, accompanied by pronation/supination
Marked compensations of the knee and hip
Occurs consistently (100% of the time)
Cannot control when prompted
Swing Phase Inconsistency
The foot tends to be toe down and slightly inverted as the leg is advancing through the air
Ankle position is weak and not reliable
Mild
Ankle plantarflexion: 0°
Occurs occasionally (less than 50% of the time)
Can correct when prompted
Can be manually corrected with mild resistance
Moderate
Ankle plantarflexion: 0–2°
Occurs frequently (more than 50% of the time)
Can improve when prompted
Can be manually corrected with moderate resistance
Strong
Ankle plantarflexion: 2° or more
Occurs constantly (100% of the time)
Cannot correct when prompted
Can be manually corrected with strong resistance or cannot be corrected
Excessive Plantarflexion/Toe walking
Bears weight primarily on forefoot
Toes point downward and heel does not touch ground when walking
Excess muscle tone, range of motion, or habit results in toe walking
Mild
Gentle excess dorsiflexion and knee flexion: 5–10°
Occurs occasionally (less than 50% of the time)
Can correct when prompted
Can be manually corrected with mild resistance
Moderate
Marked excess dorsiflexion and knee flexion: 10–15°
Occurs frequently (more than 50% of the time)
Can improve when prompted
Can be manually corrected with moderate resistance
Strong
Significant excess dorsiflexion and knee flexion: 15° or more
Occurs constantly (100% of the time)
Cannot correct when prompted
Can be manually corrected with strong resistance or cannot be corrected
Excessive Dorsiflexion/Crouching
Knees, and sometimes hips, remain flexed when standing or walking
Posture may be due to weakness or low muscle tone
