The gait analysis is an objective evaluation for total hip replacement. The author attempted to evaluate the patients of total hip replacement by gait analysis through quantification and interpretation of the pathologic gait defects by means of
the
basic parameters related to gait of the control group and the experimental group.
The control group were the five young male students who have normal gait patterns and the experimental group were fifteen patients who followed up one year after total hip replacement in our Department of Orthopedic Surgery, Yeungnam University
Hospital
from March 1986 to March 1989. We studied three distinct populations of patients.
The group A consisted of nine patients who had a unilateral total hip replacement and the contralateral hip were normal. The group B consisted of three patients who had a unilateral total hip replacement and had bilateral avascular necrosis of
the
hip.
The group C consisted of three patients who had bilateral avascular necrosis of the hip and had bilateral total hip replacement.
@ES The results were as follows:
@EN 1. The gait analysis allowed us to measure the swing time, the single-stance time, the double-stance time, the step length, the cadence, the velocity, the cycle time in the control group and the experimental group.
2. We concluded that the double-stance time and the cycle time were increased, the single-stance time, the swing time, the step length, the cadence and the velocity were decreased in the experimental group compared with the control group.
3. There were the charactristic walking patterns in the experimental group A, B and C and in the normal control group.
