Abstract


Natural gait analysis is the best analysis because it identifies not only our foot strike but also the way our whole body moves as we propagate. From this we can determine why our feet land as we do and select the best kind of supports for us. The appropriate support is vital to have to helps us avoid strains and sports injuries. Gait analysis is the systematic study of human walking. Over the past few years, there has been an increasing interest in the subject, particularly among practitioners and students of physical therapy, Physical education, sports sciences, bioengineering and several branches of medicine including orthopedics, rheumatology, neurology and rehabilitation. Gait analysis helps us to understand Kinematic analysis, temporal analysis, angular kinematic analysis,muscular activity,force analysis,pressure distribution analysis and joint dot analysis etc. There is negligible study on kinematic analysis on Indian sportspersons and hence a research gap was evident and a group of research scholars from Indira Gandhi Institute of Physical Education and Sports Sciences, (University of Delhi) are motivated to investigate of foot pressure dominance of contralateral aspect considering the morphological and functional asymmetricity of right and left lateral foot of female sportspersons. It was hypothesized that such findings will generate a new dimension of analogy of gait analysis and thereby their implication in the field of biomechanics and kinesiology. For this purpose twenty seven (27) female sportspersons, who has at least participated at state level competitions (age 17 to 25 years) were given a walking gait test to compare between left and right foot pressure distribution. The parameters were measured by using the portable pressure measurement system from Zebris.Inc,Germany(40x30cm), supported with WinFDM-S software, (Germany). Dynamic test for left and right foot was measured in step phases to determine the foot pressure distribution. The selected variables were Left Gait Line Length (LGLL), Right Gait Line Length (RGLL), Left Dynamic Test (LDT) and Right Dynamic Test (RDT).Collected data was computed using SPSS software for Mean, Standard deviation and t-test. The pressure distribution in regard to selected variables was found to be different between right foot and left foot. It was concluded that the collateral temporal kinematic at planter aspect of foot of walking gait of female sports persons are different in right foot and left foot in regard to variables namely Contact Time 12 (CT12), Contact Time (CT13) and Contact Time (CT14) whereas in regard to all other selected variables, the right foot and left foot are not different in walking gait of female sportspersons.
