Introduction: Stroke is a leading cause of death and disability in the world today. About 795,000 people are diagnosed with stroke yearly in the United States. The annual cost of stroke from medical services and disability in our nation is $ 38.6 billion dollars. Gait rehabilitation is an important aspect of neurorehabilitation with focus on attaining the most functional and symmetrical gait to prevent falls from faulty gait mechanics, and to prevent sedentary life styles and associated comorbidities. Ankle foot orthoses (AFOs) are commonly prescribed in patients with stroke to address ankle and knee instabilities and to restore a normal and safe walking pattern.The effectiveness of AFOs on various gait parameters has been reported in patients with stroke, but mostly during the chronic stages of recovery. Systematic analyses have shown that use of various types of ankle foot orthoses improve walking impairments and balance, reduce energy costs, and improve knee and ankle kinematics in people in the chronic stage of stroke recovery, greater than 6 months since the onset of stroke. It is reported that the majority of the gait improvements occur within the first 6 months following the onset of stroke. However, a limited number of studies have investigated the effects of AFOs within six months of stroke onset.
