The purpose of gait analysis is to determine the biomechanics of the joint, phases of gait cycle, graphical, analytical analysis of degree of rotation of joints, analysis of the electrical activity of muscles and force exerted on the hip joint at different locomotion during walking, running and cart pulling. Hip and ankle joint shows maximum degree of rotation during cart pulling, and knee at running. Similarly during walking the degree of rotation of hip joint is minimum and ankle during running.The stance and swing phases are maximum during cart pulling and walking respectively. The gluteus maximus, gluteus medius and tensor fasciae latae muscles are activated during stance phase and typical shows EMG signal ranges from 0.1 to 0.5 mV with extending up to 10 KHz. During the cart pulling the force exerted on hip is the resultant of various forces. The force on hip is the vector sum of the force due to the body of weight and velocity. During cart pulling, dynamic force depends on the walking velocity, body weight and load weight. If the way of cart pulling is changed i.e. design of cart pulling machine, and load bearing system then it would possible to reduce the risk.
