Furthermore,\r\nrunning related injuries have been under the scope for the last few decades.\r\nSynchronous function between the segments of the lower limbs is necessary for\r\nefficient locomotion. Patellofemoral pain syndrome is a common exercise related\r\nsyndrome and multifactorial in nature. The purpose of this study was to measure contact\r\nforces and frontal plane moments to detect the factors that are associated with atypically\r\nhigh patellofemoral joint loading in rearfoot striking (RFS) running pattern, and\r\nmoreover, which could possibly contribute to development of the patellofemoral pain\r\nsyndrome. 39 team sport female athletes with rearfoot striking pattern (confirmed with\r\nmotion analysis by calculating the footstrike angle) were accepted to perform a shod\r\nrunning along a 15-m track at 4.0 m/\ud835\udc60\r\n2\r\n. An eight-camera system (Vicon T40, Vicon)\r\nrecorded the marker positions and GRF data synchronously at 300 Hz and 1500 Hz,\r\nrespectively. The results showed that patellofemoral contact force (PFCF) correlated\r\nsignificantly with hip extension and flexion moments as well as with knee extension\r\nmoment (r= -0.576, -0.548, 0.967 respectively, p<0.05). Also spatiotemporal\r\ncomparison showed that PFCF correlated negatively with the distance between the\r\ncenter of mass (COM) and heel contact (COM \u2013 heel distance, r= -0.350, p<0.05). Knee\r\nabduction moment correlated negatively with step frequency and positively with COM\u2013\r\nheel distance (r= -0.329 and 0.355 respectively, p<0.05). In addition, knee abduction\r\nmoment and maximum knee power had a significant positive correlation (r= 0.466,\r\np<0.05). PFCF also correlated positively with knee flexion angle (r= 0.341), and a\r\nsignificant correlation existed between PFCF and maximum knee power (r= 0.467,\r\np<0.05). It can be suggested that rearfoot striking pattern might contribute to\r\ndevelopment of the patellofemoral pain syndrome. It was shown that this running style\r\nstresses the patellofemoral joint and especially the medial side of the knee due to\r\nincreased hip and knee extension moments, increased knee flexion angle and increased\r\nknee abduction moment. As the quadriceps\u2019 moment arm increased, the quadriceps was\r\nrequired to be more active to compensate the lack of activation of the hip musculature.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Ida Okkonen (idanmaok) on 2015-04-14 08:48:01.590668.
