The Sports Biomechanics Analysis Of Crus Prosthetic Disabled People Climb Stairs

Research Purpose：The disabled is a special group of the whole human population, China disabled for8296,including male for4277million, of51.55%; For women4019million, of48.45%;15~59fordisabled people3493million, of the disabled42.10%total, of which a large part of thepopulation is in employment age disabled, but because of their effects of disability, mostpeople are not only difficult worse self-care skill work, there are difficulties. This paper is astudy on this, as in specific analysis and comparison with knee below normal people wearingprosthetic for disabled in climbing a ladder based on the difference of the human body, andexplore crus artificial limbs of kinematics and dynamics parameters related to whether theeffect of ladder ability with the motion law of sports biomechanics, wearing knee prosthesiscompared under subjects to the influence of the ladder operation capacity, and in the light ofthese situations, puts forward related construction, so as to provide for the latter opinionresearch foundation of certain.Research Methods：This article through to the bodily function is normal, six people wearing prosthetic legincomplete and the personnel6people, and all the men, left leg, the knee containing buckling,can finish can be ladder movement, as control group and group respectively, using athree-dimensional image analytical and hand, foot pressure test method, research, analysis ofwearing prosthetic knee following disabled in climbing a ladder process related disciplinaryissues.Research Results：(1) a ladder stage, when ladder°Angle of15, when the average speed of normal gravity for0.9m/s, and the average speed of gravity0.75m/s, normal group73.5°Angle for kneeaverage experimental prosthetic side so, and the average Angle is the knee777,000around°(2) in30°stairs to climb, the normal group hand test about22.3mean from power, foot or so--for an average of about foot pressure value293.1N hand strength, and the mean1.98N,foot pressure about277.4N mean.(3) the whole leg out process, put the normal group’s foot pressure contact area are generallylocated on foot five phalanges area, pressure tracing has obvious had cut the ascension afterchanges. Experimental group’s foot pressure graphics area in central, and more than fullmarginal unknown. The main conclusion：(1) for the disabled in the prosthetic legs worn ladder homework finished provides a fairlygood compensatory function, but should pay attention to training its basic standing, swing,strengthen the action such as muscle strength, exercise body recovery remaining itsequilibrium ability.(2) the stability of the ladder speed to the party has certain influence, so the calf prostheticdisabled for functional recovery is not recommended, daily life, rapid climb.(3) ladder larger Angle required the smaller arms and legs, and power knee bucklingamplitude also can reduce the ladder, this to improve the safety and comfort of homeworkoffer some support.(4) from the hands of strength look, ladder activities compared with foot strength handstrength greater change sex and higher alertness and foot power more need is stability, and thecalf prosthetic the contrary.
