CLINICAL APPLICATION PROJECT Pathological Gait Analysis
Multiple video views of a patient walking on a force platform were collected.
The video images were digitized, transformed using 3-D DLT, and then smoothed using a quintic spline.
Simultaneous data integration was performed with video images, 3-D stick figures, ground reaction force (GRF) vectors superimposed on the video images, and kinematic/kinetic data presented in tabular and graphic formats (See Fig. 1).
Kinematic and kinetic data were calculated for the gait phases of heel-strike, mid-foot, and toe-off during the patient’s right and left walking strides (See Fig. 2).
The visual and numerical integrated data presentation assisted the clinician in evaluating the perturbance of the gait mechanics due to leg length differences.
