Abstract
A stroke is caused by a lack of blood supply to the brain, and can result in a loss of function to parts of the body. Post-stroke related complications caused disability in two thirds of post-stroke survivors. Ankle Foot Orthotics (AFOs) are often prescribed to aid individuals in regaining ambulatory function, if possible. Thermoplastic AFOs have been commonly prescribed, but carbon fiber AFOs have gained traction within the industry. There is a need for more research pertaining to the benefits of carbon fiber as well as other potential composites. This study on the comparison between AFO types on functional and satisfaction levels in wearers with chronic stroke, expanded upon the existing research. The study recruited 12 participants and examined how the variables of energy cost, walk speed, and overall satisfaction were impacted by various fabrication materials. The participants were randomly assigned into four groups under different AFO conditions (wearing a carbon fiber AFO, wearing a carbon/fiberglass hybrid AFO, wearing a fiberglass AFO, and wearing a thermoplastic AFO). The data collection methods consisted of a six minute walk test, energy cost return analysis (using a portable Metamax 3B system), and a mixed (quantitative and qualitative) questionnaire. The data from this study would expand the research around various fabrication materials and allow professionals to further customize AFOs to a patient’s specific needs.
