摘要：The main purpose of the present work was to describe a protocol for making a prototype of a low-cost customized orthosis to facilitate gait in patients with spastic paraplegia in the lower limbs, leading the reader to understand the indication for use, the making, and the components of the orthosis, which has the objective of reducing some of the specific difficulties of the lower limbs in walking and providing low costs in its manufacture. This is a study that was developed following a quantitative approach, parallel to a literature search on aspects relevant to orthosis manufacturing. The study was guided through the prototyping stages: literature review on the theme, product manufacturing, and technical adjustments before applicability. This study presented the description of a low cost method for the development of a prototype of a customized orthosis for lower limbs. After the first prototype was ready, the first fitting of the orthosis was performed on the authors, and, after the observation of the need for adjustments, a second prototype and a third prototype were made. The first prototype was created with a piece of mattress foam tied to an elastic, which was improved, and from it the second one was created with Velcro on the ends of the elastic, and then improved with a cover with jeans fabric and elastic bands with a nylon fabric suspender attached to a fabric belt, which prevents excessive abduction of the hips during gait. It is evident that this resource still needs further studies and patenting process so that its application can be guaranteed with full scientific support, but in general, it was possible to develop a customized orthosis with low-cost materials and tools, where the described procedures may help in the development of assistive products and provide dissemination of this knowledge in institutions that dispense orthoses.
