Study On The Level Ground Walk Gait Characteristics Of Adolescents With Cerebral Palsy

Nowadays there are lots of disable persons; the cerebral palsy crowd is a part of disabledpersons. Cerebral palsy is a symptoms complice of central dyskinesia and posture abnormalcaused by brain damage from before birth to newborns; it is often accompanied by mentalretardation, epilepsia, language barrier, low aural comprehension, vision abnormal, andbehavior abnormal etc. Cerebral palsy is almost a lifelong illnesses, if it is not properly treatedduring childhood, it will have sequelae with lifelong. According to relevant reports, there are90%children cerebral palsy can live till adult or old age, estimated average life expectancy is30years old and so the adolescence is a necessary process for cerebral palsy crowd; for anormal person, walk is essential activity way, persons moving base depends on legs walk. Thenormal walk does not need thinking but walk’s control is very complicated including centralnervous system order, body balance and coordination control, it refers to foot, ankle, knee, hip,body, neck, shoulder, arm’s muscle and joint coordination activity, any link’s imbalance ispossible to affect gait stability. Walk is very important for cerebral palsy youngsters, but bodydisability must affect their gait thereby affect their normal life.In this text one healthy teenager and four adolescences with cerebral palsy (two are GrossMotor Function classification Ⅰ level, two are Gross Motor Function classification Ⅱlevel) subjects, with their gait characteristics as the research object, respectively from thekinematics, the three dimensional force measurement, lower limb joint torque and footpressure distribution in four aspects: natural walking gait were flat characteristics of theanalysis of the research. Kinematics research results showed that adolescences with cerebralpalsy when walking the ground around the support of lower limb is asymmetric, and hassignificant; In support of the body and swing phase when there are abnormal, in support of thephase to the existing support unusual, main show is in full turn, sufficient evaginate, toesbuckling and knee excessive excessive buckling, hip too adduction or buckling, above tosupport unstable lower performance; Swing phase of the main exceptions have sufficientprolapse, hip, knee stiffened buckling and adduction of the hip or limited too adduction causescissors steps.The main3d measuring forces research results, cerebral palsy vertical force value curveteenagers a normal person difference is bigger. The impact of the initial landing is larger, the main reason is the subjects to the limb support, to lead the side body on the ground landingthe impact of the instantaneous increases, the vertical force value curve performance is forcevalue of increased suddenly, the emergence of a peak; Overall vertical force value curve is nottypical of the twin peaks present state, in rough classification level Ⅱ function of theparticipants appear "three peaks" curve state.Through the method of dynamics in the lower extremities, reverse joint torque ofcalculation, found that gross motor function classification Ⅰ levels of cerebral palsyteenagers, lower limb each joint torque in the whole gait cycle of the changes in the situationis closer to the normal teenagers, but in the initial landing stage ankle adduction outreachabnormal in torque, leading to the full support "inside eight""the eight"; Gross motor functionclassification Ⅱ levels of cerebral palsy teenagers, during walking in the changes of the jointtorque than normal teenagers have significant difference, in the whole process of the kneejoint on foot hip buckling torque is bigger, lead to hip knee can’t fully extended, the influenceof the coordination on foot, swing phase) of the hip adduction large torque caused by lowerlimbs were too adduction, form the scissors.Through to the foot pressure plate test data analysis found that normal teenagers initiallanding, heel first touchdown, maximum pressure concentration on the heel place, with thesupport of the continuation of pressure in the center the central place of foot forward; Ⅰlevel classification bulky function cerebral palsy teenagers foot pressure distribution is morenormal teenagers and no significant differences, bulky function Ⅱ classification level ofcerebral palsy teenagers foot pressure distribution is more significant difference of normalteenagers, and its feet or so the pressure distribution difference is bigger also: the initiallanding, the main stress on before the foot palm, the main reason is the subjects in full swingphase) in the initial landing and drooping feet palm ground first; Pressure center mobile linefrom the centerline of the foot is larger, is the main reason of the unstable support subjects;Foot inside and outside the turn in support of the phase, a foot on the maximum pressure inthe foot, so that lead to the increased support reduce more supporting surface instability.Based on level ground walking gait the adolescences with cerebral palsy features, the mainbody of the anomaly is supporting no stable, swing phase every link with abnormal mode.Suggestions of the adolescences with cerebral palsy in rehabilitation training to strengthen thetraining of the balance ability, strengthen physical movement coordination of practice, strengthen the lower limb strength exercises; In view of their own physical cerebral palsycerebral palsy teenagers, in the training process must reasonable arrangement good trainingintensity and time; Due to cerebral palsy teenagers most for spasms type, so in the trainingprocess increase necessary vibration relax training.
