What is an example of a condition that may require rigid orthotics?

Rigid orthotics are designed to provide significant support and stability to the foot and ankle, making them suitable for various conditions that impair normal biomechanics. Charcot-Marie-Tooth disease is a hereditary condition that affects the peripheral nervous system, leading to muscle weakness and atrophy, particularly in the lower limbs. Individuals with this condition often experience foot deformities, such as high arches or drop foot, which can severely disrupt their ability to walk properly.

The use of rigid orthotics in this context helps to align the foot and maintain its structure, preventing further deformity and improving overall function. By providing a stable base, rigid orthotics can assist with gait mechanics, reduce the risk of falls, and improve mobility for individuals with Charcot-Marie-Tooth disease.

The other conditions mentioned, such as flat feet, plantar fasciitis, and Achilles tendonitis, may often be treated with different types of orthotic devices, such as semi-rigid or soft orthotics. These conditions typically involve overuse or alignment issues, where flexibility and cushioning provided by softer materials may be more beneficial than the stiffness of rigid orthotics.
