Just in case you need more than the standard AFO. Ask your therapist for that 3d motion analysis system. I think that is more important than the KAFO.
The purposes of this study were to develop a new orthosis controlling
ankle and knee joint motion during the gait cycle and to identify the
effects of the newly designed orthosis on gait kinematics and
tempospatial parameters, including coordination of the extremities in
stroke patients. Fifteen individuals who had sustained a stroke, onset
was 16 months, participated in this study. Before application of the
measurement equipment the subjects were accustomed to walking on the
ankle-foot orthosis (AFO) or stance control knee with knee flexion
assisted-oil damper ankle-foot orthosis (SCKAFO) for 5 minutes. Fifteen
patients were investigated for 45 days with a 3-day interval between
sessions.
Measurements were walking in fifteen stroke with hemiparesis
on the 3D motion analysis system. Comparison of AFO and SCKAFO are gait
pattern. The difference between the AFO and SCKAFO conditions was
significant in the gait velocity, step length of the right affected
side, stance time of both legs, step-length asymmetry ratio,
single-support-time asymmetry ratio, φ-thigh angle and φ-shank angle in
the mid swing (p<.001). Using a SCKAFO in stroke patients has shown
similar to normal walking speeds can be attained for walking efficiency
and is therefore desirable. In this study, the support time of the
affected leg with the SCKAFO was longer than with the AFO and the
asymmetry ratio of single support time decreased by more than with the
AFO. This indicates that the SCKAFO was effective for improving gait
symmetry, single-support-time symmetry. This may be due to the decrease
of gait asymmetry. Thus, the newly designed SCKAFO may be useful for
promoting gait performance by improving the coordination of the
extremity and decreasing gait asymmetry in chronic stroke patients.
