The goals of bracing in polio and postpolio are to optimize joint position and support weak muscles with the goal of reducing falls, reducing deformities, and optimizing energy conservation. Orthoses are primarily used in the lower extremities to optimize gait. Less frequently, upper extremity orthoses are required. Polio survivors are at increased risk of falls and injuries. Appropriate bracing and compliance with the prescribed device can prevent falls and injuries. The best orthotic results are often achieved with patients who have significant deficits but walk regularly, are well motivated, and are willing to adapt their gait for orthotic use.
