Spastic Paresis

The purpose of this study is to evaluate the mechanical properties of the Achilles tendon (stiffness, length, volume) and the force production capacities of the gastrocnemius medialis muscle in patients with spastic paresis (post-stroke or incomplete spinal cord injury) compared to healthy subjects, during gait.

The research is being done to compare two methods of creating AFOs: 1. The traditional method, which involves manually creating a mold from a plaster cast of the client's limb. This is time-consuming and labor-intensive; and 2. The newer method uses digital technology, such as 3D scanning and printing, to design and produce the AFOs, potentially making the process faster and less costly. We want to know whether AFOs made using digital technology can provide the same clinical benefits as those made traditionally.
