Physical Therapists will benefit from this course as the use of orthotic devices are common in todays advancing medical field. One of the most common types of orthoses are AFOs which can be used to treat foot drop secondary to neuromuscular conditions. Understanding the difference between an anterior and posterior ankle foot orthosis can impact biomechanics and gait. Understanding the level of biomechanical control associated with each orthosis can facilitate an understanding of the clinical indications. Physical therapist will gain unique perspective of the material science properties of composites and analyze the difference between thermoplastic AFO’s and "Carbon Fiber/Composite" AFOs. By analyzing the different composite AFO profiles Physical Therapist can simplify the decision-making process for identifying the correct AFO for a patient. By understanding key clinical indications/contraindications, materials and pathology presentations the PT will be able to determine appropriate outcome measures related to AFO’s based on psychometric properties and patient goals.
