The posterior leaf spring AFO provides which primary benefit?

Explanation:
The key idea is that a posterior leaf spring AFO is a dynamic device designed to aid ankle dorsiflexion during gait. Its flexible posterior leaf stores energy as the foot tends to plantarflex, and then releases that energy to gently lift the foot into dorsiflexion as the leg advances. This helps maintain toe clearance in swing and reduces the risk of foot drop, which is its primary benefit. It’s not mainly about limiting plantarflexion, stabilizing the knee in early stance, or accommodating volume changes, so dorsiflexion assistance is the best fit.
