Objective: To examine the practical usefulness of a
simplified three-dimensional treadmill gait analysis
with a Lissajous overview picture (LOP), a holistic
figure of marker trajectories, to present the effect of
ankle-foot orthoses (AFO) on hemiparetic gait.
Methods: Seven patients with hemiparesis who were
able to walk without an orthosis or gait assistive device
were included in this study. Patients were measured
with a simplified three-dimensional treadmill gait
analysis system as they walked with and without an
orthosis in a rehabilitation center of a university
medical center. Gait was analyzed using the LOP,
and quantitative comparisons were made to evaluate
the changes in joint angles and joint position
displacements during the swing phase.
Results: Using the orthosis decreased ankle plantar
flexion during the swing phase (p = 0.028) and
significantly reduced compensatory patterns, including
hip elevation, knee elevation, and circumduction (p =
0.028, 0.018, and 0.028, respectively).
Conclusions: The quantitative assessment by a
simplified gait analysis system clarified the effect of
AFO on reducing the compensatory movement in a
hemiparetic gait. The use of LOP helps to understand
the holistic effect of AFO and to analyze the individual
patterns of gait disturbance.
