What configuration would you use for plantarflexion spasticity?

In the context of managing plantarflexion spasticity, using a posterior rod is effective because it provides resistance against excessive plantarflexion. The goal is to control the overactive muscles responsible for the spasticity—typically the gastrocnemius and soleus—that cause the foot to point downwards. By applying a posterior rod, the orthotic braces can create a force that helps maintain the ankle in a more neutral position, thereby improving functional mobility and stability during walking.

The posterior rod configuration effectively counters the spasticity by applying a stabilizing force that aligns the ankle joint into dorsi-flexion, facilitating better alignment of the whole extremity, which is crucial for proper gait mechanics. This approach also helps to prevent contractures, maintain joint range of motion, and enhance the individual’s ability to engage in activities of daily living.

This rationale is central to the effective management of plantarflexion spasticity, ensuring that the individual can perform movements more effectively and comfortably.
