Quick answer: Stroke is one of the most common causes of foot drop. Clinical trials, including the multicenter FASTEST trial (197 participants), show that AFO braces produce significant improvements in comfortable walking speed for stroke survivors with foot drop. Recovery and results vary by individual, and AFO bracing is typically used alongside physical therapy.
Why Stroke Causes Foot Drop
A stroke can damage the areas of the brain responsible for sending signals to the muscles that lift the foot, resulting in foot drop on the affected side. The severity and recovery trajectory depend heavily on which brain regions were affected and how quickly rehabilitation begins.
What Clinical Research Shows About AFO Bracing After Stroke
Several randomized controlled trials have specifically examined AFO bracing in stroke populations:
- The FASTEST trial, a multicenter randomized trial, enrolled 197 participants at least 3 months post-stroke with a gait speed of 0.8 m/s or slower. Both the AFO group and the foot-drop-stimulator group showed significant improvement in comfortable gait speed from baseline to 30 weeks. (Source: American Heart Association journal Stroke)
- A multicenter randomized crossover trial comparing a foot-drop stimulator with a conventional AFO over 12 weeks found that both devices had significant orthotic and therapeutic effects on walking speed. (Source: PubMed)
- A systematic review of AFO effects on gait velocity and cadence in stroke patients found generally positive effects on walking speed across the reviewed studies. (Source: PMC systematic review)
Fall Risk After Stroke
Falls are a major concern during stroke recovery. Research indicates that between 14% and 65% of stroke patients fall at least once during hospitalization, and between 37% and 73% fall during the first six months after discharge.

What This Means for AFO Brace Use After Stroke
The evidence base for AFO bracing improving walking speed after stroke is relatively strong and consistent across multiple trials. Evidence specifically for fall prevention is more mixed and still developing — which is why AFO bracing is generally recommended as part of a broader recovery plan that includes physical therapy, not as a standalone fall-prevention solution.
Frequently Asked Questions
Does research support using an AFO brace after a stroke?
Yes. Multiple randomized controlled trials, including the FASTEST trial, show AFO bracing significantly improves walking speed in stroke survivors with foot drop.
How common are falls after stroke?
Research shows 37–73% of stroke patients experience a fall in the first six months after discharge from the hospital, making gait support and fall-prevention strategies an important part of recovery.
