Study On Plantar Pressure Characteristics Of Teenagers Wearing Heelys

This study analyzed the dynamics index characteristics of the teenagers wearing Heelys whenthey walking and sliding. It was discussed the possible reasons of plantar pressure characteristicsproduced by Heelys and the possible damage on young people in this paper. Theoretical referenceswere wanted to provide to the manufacturers.The German Novel Pedar-X plantar pressure test system is used in this experiment.15maleadolescents participated in the test. First, each subject wore sneakers walking on the20meters long,3meters wide passageway three times; than they wore Heelys walk with and without wheels.Finally, the boys wearing Heelys open pulleys taxiing three times on the way at the speed of3m/sec, two minutes between each test. Index was collected the last5seconds of every state. NovelDatabase essential analysis software was used to analysis the peak pressure, contact area, impulsedata to understand dynamics indicator features when youngsters wearing Heelys walking andtaxiing.The data showed that walking in sports shoes, Heelys without wheels, Heelys with wheels,there were significant differences in peak pressure, peak pressure, the contact area the impulse ofeach region. Sliding experiments showed that compared with sports shoes, the heel impulse inHeelys are5times of sneakers. Right foot heel lateral and left foot heel lateral peak pressure has avery significant difference; the contact area has significant difference. Very significant differenceswere found in medial peak pressure, peak pressure, contact area and impulse in heel medial.Due to teenagers wearing Heelys go compared with the ordinary sports shoes have significantdifference, the gait changes, so teenagers should not be wearing heelys for a long time. Teenagerswearing Heelys long may lead to fatigue periostitis or metatarsal stress fractures, plantarinterdigital bursitis, plantar fasciitis. When teenagers wearing Heelys gliding, action required inorder to maintain the posture of the ankle plantar fascia90degrees, plantar long and short ligamenthas been taut, plantar long and short ligament laxity appears, fallen arches, plantar fasciaattachment points as slippery walking ebbed and flowed, repeated stimulation, gradualdegeneration, the formation of aponeurosis dead end of the disease, heel spurs will be generated.
