Hemiparesis is one of the most common impairments after stroke that contributes to reduced gait performance. The ability to walk is a primary goal for people with stroke and most stroke survivors regain the ability to walk.
Hemiplegic gait is characterized by decreased walking speed and energy inefficiency. Persons with hemiparesis walk significantly slower than healthy persons and after 6 months reach only 40–50% of the distance of age-matched healthy persons. As an adjunct to therapy, ankle-foot orthoses (AFO) are frequently used, although evidence is limited that an AFO improves elements of gait.206495
