Clinical Trial Summary

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.


Description:

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. Participants undergo testing in the gaitlab after using the new brace for a period of time. 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.

Outcome

Type Measure Description Time frame Safety issue
Primary Self-selected Walking Velocity walking velocity will be assessed by an electronic temporospatial foot-fall measurement system (gaitmat) 8 weeks
Primary Step Length Symmetry step length symmetry will be assessed by an electronic temporospatial foot-fall measurement system (gaitmat). symmetry will result in a ratio of step length on more involved or affected side compared to the less involved or affected (i.e. the "normal") side. as such, the measure will appear to have no units but actually will be a ratio of the same units (in this case, meters to meters). 8 weeks
Primary Step Time Symmetry step time symmetry will be assessed by an electronic temporospatial foot-fall measurement system (gaitmat). symmetry will result in a ratio of step time on more involved or affected side compared to the less involved or affected (i.e. the "normal") side. as such, the measure will appear to have no units but actually will be a ratio of the same units (in this case, seconds to seconds). 8 weeks
Secondary Joint Kinematics joint kinematics will be assessed using motion capture system 8 weeks
Secondary Joint Kinetics joint kinematics will be assessed using motion capture and biomechanical force measurement systems 8 weeks
Secondary Activity (Step Count) activity will be measured using accelerometer based step activity monitoring devices 8 weeks
Secondary Subject Opinions subject opinions will be measured using surveys and questionnaires 8 weeks
