The aim of this study was to analyze the biomechanics of hemiparetic (HP) gait in terms of spatio-temporal parameters and kinematic measurements and, to compare the values of gait parameters of HP persons with those of matched able-bodied controls. Sixteen female and 30 male stroke patients with a mean (SD) age of 58.0 (7.5) years, and age, sex, height and weight matched normal controls participated in the study. Spatio-temporal parameters (walking velocity, step time, step length, double-support time, stance time) and kinematic variables (joint rotation angles of pelvis, hip, knee and ankle in sagittal, coronal and transverse planes) of HP patients and controls were compared. HP patients displayed slower walking velocity with shorter and asymetric steps. Excessive displacement of center of mass was observed. The difference between the groups regarding the peak flexion and extension degrees of hip and knee were statistically significant. Forty-one percent of the patients had stiff-knee pattern and 35% had genu recurvatum at paretic side. Subtle gait deviations were observed on nonparetic side. As a conclusion the resultant gait pattern of patients with HP due to stroke is a mixture of deviations as well as the compensatory motion dictated by residual functions. Since computerized gait analysis yields objective and reliable data, it is of great value in planning the treatment strategies.
