Ankle Foot Orthosis Comparative Effect — AFOCE  

Foot Injuries and Disorders Clinical Trial

Official title: Comparative Effect of Commercially Available Custom Dynamic Orthoses (CDOs)

Status Completed

Clinical Trial Summary

The proposed effort is designed to support evidence-based practice and optimal care by evaluating how the form, fit and function of two commercially available carbon fiber custom fit braces (Orthoses) influences outcomes following extremity injury. Early data suggests that custom fit carbon fiber braces can significantly improve function following severe lower leg injuries. The proposed study will provide evidence that can be used by clinicians to guide their practice, including care for service members, veterans and civilians who have experienced a high-energy traumatic injury to their lower leg.

Clinical Trial Description

In this research study, adult participants who have sustained a below-the-knee traumatic injury greater than two years ago and are still experiencing deficits including weakness and/or immobility will be assigned to one of two brace sequences (AB or BA). Participants will be randomized to a particular sequence, with an equal chance of getting either order. Participants will be evaluated under 4 conditions: no device, standard of care, and 2 carbon fiber custom dynamic orthoses (CDO), the Reaktiv device from FabTech Systems and the PhatBrace by Bio-Mechanical Composites Inc. Participants will be tested with no device and standard of care at baseline, after 3 months of accommodation to the Reaktiv, and 3 months of accommodation to the PhatBrace. A series of study measures will be performed. The physical performance measures will incorporate tests of agility, balance, speed and lower limb power. Questionnaires will be used to evaluate participant's perceived comfort and smoothness, pain, preference, and semi-structured interviews will be used to fully capture the perspective of the participant. A motion capture system will be used to evaluate walking mechanics, allowing comparisons between conditions. Lower limb forces and body motion will be assessed using computerized motion capture and force plates in the floor, as individuals walk over-ground. Small reflective markers placed on the participant's skin and force measuring plates in the floor will be used. The investigators will also complete mechanical testing of the devices and collect demographic and descriptive data. ;
