Ankle Foot Orthotic
What Is an Ankle Foot Orthotic?
An ankle foot orthotic, or AFO, is a custom medical brace that controls the foot and ankle as a single unit. Unlike standard custom orthotics that sit inside a shoe, an AFO extends up the lower leg to stabilise the ankle joint and influence gait at multiple points.
AFOs are prescribed when in-shoe orthotics are no longer sufficient to manage instability, weakness, or progressive deformity. They are a clinical step up, not a parallel option.
- Controls the foot and ankle joint together
- Manages weakness, instability, or paralysis
- Slows the progression of advanced deformity
- Restores a safer, more efficient walking pattern
When an AFO Is Prescribed
Drop foot
Post-stroke gait dysfunction
Charcot foot
Posterior tibial tendon dysfunction (PTTD)
Post-surgical stabilisation
Neuromuscular conditions
AFO vs Custom Orthotics
The distinction matters because patients are often prescribed an AFO after standard orthotics have stopped delivering enough correction.

Types of AFO We Provide
A rigid brace providing maximum control. Best for severe drop foot or post-stroke gait.
Hinged at the ankle to allow controlled motion. Suitable for patients who retain some ankle movement.
Flexible polypropylene design that assists toe clearance during swing phase.
A semi-custom hinged AFO with foot orthotic integration. Particularly effective for PTTD and adult-acquired flat foot.
Lightweight, energy-returning brace suited to active patients with drop foot or mild weakness.
How the Fitting Process Works
1
Clinical Assessment
Review of medical history, neurological status, mobility goals, and prior bracing experience.
2
Biomechanical Examination
Detailed evaluation of joint range, muscle strength, alignment, and weight-bearing patterns.
3
3D Scan or Casting
High-precision capture of foot and lower leg shape for custom fabrication.
4
Fabrication
The AFO is manufactured in medical-grade materials matched to your weight, activity level, and clinical need.
5
Fitting and Gait Retraining
Initial fitting, comfort adjustments, and supervised gait practice to ensure safe, confident walking.
Why Professional AFO Fitting Matters
- Off-the-shelf braces frequently misalign forces and can worsen symptoms
- Correct prescription requires neurological, biomechanical, and structural assessment
- Adjustments over the first weeks are essential for comfort and adherence
- A poorly fitted AFO is often abandoned, leading to falls and further deformity
A Real-World Note on Why This Matters
In a systematic review on AFO use in chronic stroke (Tyson and Kent, Clinical Rehabilitation 2013), patients fitted with appropriate AFOs showed significant improvements in walking speed, balance, and stair-climbing ability compared with no bracing. The clinical takeaway is consistent: the right AFO restores function that exercise alone cannot.
About Our Clinic & How We Help
At Emerald Hill Podiatry, AFO prescription is led by Singapore’s only surgically trained podiatrist. This matters for advanced cases such as Charcot foot or PTTD, where the AFO must complement, and sometimes delay, future surgical options. We coordinate with neurologists, vascular specialists, and physiotherapists where indicated.
Book Your AFO Consultation
If standard orthotics are no longer enough, an AFO may restore the stability and confidence you’ve been missing. Book your assessment to find out which bracing solution suits your condition.
