Paper details:
have been in vicon lab to see a patient gait with use of vicon system. i have started and write down 500 words but the demand 1000 words more.in total 1500. i have uploaded 2 docx files.
Vicon is a tool that enables evolsution of gait, and it lead us to provide evidence of their variation from normality. It is possible to repeat the analysis many times in a short period of time. It plays a significant role in the movement analysis of human. In addition, it works with 3D system to illustrate very effectively in the analysis. In reality, It may characterize each patient’ locomotory (1) .We had analysis a patient has left prothetic limb limb, in the essay I will exMIN.
Many data could be obtained from gait analysis for example. Kinematic and kinetic data for lower limb. Usually a study, such as looking for a treatment outcome or how patient walk in order prosthesis, orthosis. First, reumerous kinematic and kinetic parameters after that analysis of each signal parameter. The body divides to segments foot, knee and believe gradual, and 3 planes are observed sagittal, coronal and transverse. Moreover, the useful markers are taken posteriorly from calcaneus, distal leg sacral tubercle. Lateral from Fibular head, Great trochanter centre of deltovel. Anteriorly from knee caps, Assis’s. In addition, patient Wight, length, and knee width should be entered to the software and identify the left and right leg.
First of all the foot progress angles. There are two motion acour in it; the dorsflexion and plantarflexion. Extion of the ankle introduced a functional error in all of the gait phases in both legs. Typically in lnitall contact the foot starts with just above dorsflex. The effectiveness of the heel rocker which helps shock absorption and progression was missed. During the mid-stance the excessive plantarflexion tibial advancement. Any limitation that restricts flexion to less than 50 by the 30% point in the gait cycle represents an abnormal restraint. Also, losing of the ankle joint rocker may lead to a short stipe length by other limb.in the terminal stance the patient was able to roll onto the forefoot. However, excessive plantflexion caused an increase on heel rise and sharp loading in the right leg. The knee flexion was present in the pre-swing due to a chive of roll onto the forefoot previously. In the rest of ankle joint phase the two movement went normally.
Second in the knee joint most movement take place in the sagittal plane. They are called flextion and extinction. Because the patient has hip disarticulation. The knee was artificial one. As the graph shows there were limit knee flexion. That may effect in three phases during the gait loading response, pre-swing and intial swing. At heel rokere phase lack of knee flextion may affect the shock- absorbing. Pain may be assoated with this failr and body weight be directly transfer from femur to the artificial leg withous muscle cushining. That is could cause greet moment from the front plan on hip joint, and lead to unstable trunk. So that the patient uses a stick to help him is stability, and slow his walker in order to reduce the accelation. Furthermore, the knee makes take-off more difficult. By looking to kinetic graph the moment increased rapiclly that cause increase the eneray coast of walking. In the foot off swing phases the flexion increased dramitckly but in loadin and mid-stanee went correctly in the other free joint. In the coronal plane the terms abduction or valgus and adduction in other words Varus. The normal abduction around 10 represents of femur. However, the tibia is vertical.
