An fabricating orthosis for a 9-yr-old who had an elbow capsulotomy and triceps lengthening procedure 2 days ago. The goal of the surgery was to increase the
child's ability to flex the elbow beyond 90° for greater independence during activities such as self-feeding and self-care of the face, teeth, and hair. What type of orthosis is indicated at this stage of healing to support progress toward this goal?
a. Dynamic extension orthosis to allow active elbow flexion and extension through a full arc of motion
b. Long-arm thermoplastic immobilization orthosis to position the affected elbow in complete extension
c. Elbow mobilization flexion restriction orthosis to allow controlled passive ROM from 0° extension to 90° flexion
