Comparison of the Functional Walking Outcomes of Two Settings of a Commercially Available AFO in Adult Stroke Patients
Comparison of the Functional Walking Outcomes of Two Settings of a Commercially Available AFO in Adult Stroke Patients
The purpose of this study is to evaluate how two different settings of a commercially
 available ankle foot brace affect how stroke patients walk. The study brace is an ankle foot
 orthosis (AFO) that makes use of a newer type of joint that contains a soft insert, in
 addition to the conventional hard stops, to limit the range of motion of the ankle during
 walking. The results of this study will help to clarify 1) whether and how this new joint
 affects the way you walk, 2) whether it makes it easier for the clinician to align your brace
 and 3) your opinions about the new joint.
