Abstract
In an attempt to carry out a more dynamic analysis of gait than that accomplished by conventional means, we analyzed so-called normal gait by photographing it with a mobile 16mm movie camera from both the sagittal and coronal planes, and then analyzing the motions of various location with a motion-analyser and processing the data obtained with an electronic computer.
The result of this was that no difference could be seen in the analysis of gait one plane and that two planes. However, similar determination of experimentally induced abnormal gait, and processing of data obtained, revealed significant differences between the two planes in cases of abnormal gaits with large angles of movement of joints. Also, trends similar to those described in many earlier reports were noted in regard to hip joint angles of extension and flexion and angles of adduction and abduction, knee joint angles of extention and flexion, and foot joint angles of planter and doral flexion, while findings more or less diff erent to those of earlier reports were noted in regard to hip joint inner and outer rotation and horizontal adduction and abduction, and pelvic rotation, femoral rotation and foot rotation.
It can be claimed, on the basis of these findings, that photography from three planes is necessary for accurate determination of the rotation of pelvic, , hip and foot joints, although photography from the sagittal and coronal planes is sufficient for determination of the angles of extension and flexion of hip, knee and foot joints.
