Abstract

The paper presents the results of gait parameters as a function of unilateral weight. The object of the research was a woman walking on a stationary surface and carrying in his hand weights from 0 to 15 kg. Her movement was recorded by 6 cameras recording the location of 34 markers placed at appropriate points in the body. 3D reconstruction was performed for each of the reflecting markers. Tested signals were changes in the value the joint angles of ankle, knee and hip. On the basis of about 6 cycles of movement of each load, a model for the average gait cycle was developed. The result of the experiments are graphs of changes the joint angles as a function of time, bilateral cyclograms, synchronized bilateral cyclograms and regression lines. The conclusion of the study is to determine how one-sided load affects gait asymmetry. Simple and easy to interpret method of presentation of results were also shown. Studies were conducted using VICON system.
