The Study On The P.E Collage Students' Ankle Joint Sprain By Foot Dynamics

Purpose: In athletics teaching and the lesson remaining activities of the high school, the student participates widely, the sport items involve multitudinously, the sport hurt occurrences more frequently, and the physical institute students occurrence the ankle joint sprain, even more commonly and frequently. Because cognition of the student to the ankle sprain is not enough and the outbreak process arises not obviously, it is hard to cure the disease.Therefore we want to summary foot bottom pressure of the athletics college university students who have the ankle joint sprain and the foot bottom pressure of normal university student. It is propulsive to understanding foot bottom pressure characteristics thoroughly, to diagnosis and cure the ankle joint sprain early. We provide the foot bottom dynamics index sign to help people understanding ankle joint hurts.Conclusion:1 . The intensity of pressure of the foot bottom pressure system expressed that the intensity of pressure changed unsteadily and the intensity of pressure of the two foot is not symmetrical. The one who turn over sprain inside the ankle sprains the foot with normal person's difference notability, ankle inside turn over to sprain normal foot with normal the person compare, the left side ankle inside turn over to sprain the difference notability, the right side ankle inside turn over to sprain the difference is not obvious. Among them left side inside turn over to sprain a left foot inside turn over the phenomenon to notability, right side inside turn over to sprain a right foot inside turn over the phenomenon not obvious.2. The foot bottom pressure system pressure part expresses, stage slowly and soon, inside turn over the foot pressure variety rate big in normal foot; With the speed, the extension that exercise to keep on time, each test-receiver all expresses is small inside the variety rate of turn over the foot in normal foot.The left side ankle joint inside turn over the pressure variety rate of sprain to have the bigger difference with normal person, the right side ankle joint inside the one who turn over to sprain is not obvious, possibility and experiment strong side body relevant. The ankle joint inside turn over to hurt inside turn over the foot average a time aspect differ not obviously, so prognosticate usually not easy distinguish. Experiment a whole Sigma obvious high in matched control, explain to experiment the set inside turn over to hurt the similar to normally foot at speed of foot of a time up, express for unsteady, undulate sex big, but the extension that steady list of matched control treads a ground of time to help to keep on time with sport.3. In the variety of the foot bottom pressure center, the ankle joint inside turn over to hurt a foot and to should of a foot of matched control difference notability, performance for ankle inside turn over to hurt of inside turn over the foot pressure variety rate low with matched control normal foot, but did not take place inside turn over to hurt the foot high in matched control normal foot; The ankle joint inside turn over to hurt at slowly and soon or the sport expressed in the early years not obviously, along with sport the increment performance of the quantity obvious.Expresses from the pressure center change the portrait, or so two fan-shaped districts of the matched control variety ratio experiment the set is even, explaining that the or so foot pressure of matched control have no the obvious abnormality, the pressure that a foot bear is more and equally. Experiment the set inside turn over to hurt the foot pressure small in normal foot, may be because the normal foot is for reducing to hurt the ankle joint to carry the lotus, but the protection pressure to build up that adopt.
