Research On The Characteristics Of Plantar Pressure Distribution In The Normal Walk And Fast Walk Older

Using plantar pressure system text in Changchun City Dong ling Street, the elderly community centers for nine elderly subjects, access to the elderly in both normal and fast travel speed of a single step foot kinetic parameters. Purpose is to reveal the elderly in travel speed of changes in plantar pressure patterns and characteristics, fitness for the elderly the choice of methods proposed To prevent the elderly because of bone fatigue foot injury to provide a scientific basis.The main conclusion from research:First, walking speed of the change is affecting the elderly plantar pressure change of the main factors. Test samples drawn from the preliminary conclusions of human walking is the plantar pressure distribution is bimodal curve older people in different travel speed circumstances, the peak plantar pressure was concentrated in the second metatarsal and the heel side. The first curve peaks with representatives of the elderly enough to the ground reaction force, the greater the peak, Reaction to the ground reaction force is, the two peaks of the time gap between the elderly embodied foot buffer capacity The greater the margin the better buffer, the second peak on behalf of the elderly foot palm pushed the advance stage, its size and slope of the elderly reflects the foot muscle strength;Second,in a single step, the first with the heel area, after the transition to the foot; from the heel first, followed by foot from the Central District, before the soles of the feet from the outside, the final first metatarsophalangeal joint and the first from the toes; peak pressure was seen in the heel or the second metatarsophalangeal joint, peak pressure zone pressure change rate is the largest regional, fast running plantar pressure, the foot susceptible to injury, Older persons should pay attention to the speed of running, in order to avoid injury. Third, With the increase in travel speed, plantar pressure center tracks changes in the X-axis displacement rate decreases and the Y-axis displacement rate changes increased plantar pressure center showed Advancement, hints fast walking speed, the elderly have no stability, the phenomenon is likely to cause physical balance has been destroyed.
