No. of bitstreams: 1 briani_rv_me_prud.pdf: 1227362 bytes, checksum: 49d10bd4f3fe6415ab0a5a62cfd21c11 (MD5) Previous issue date: 2017-05-12 / Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) / O estudo da loading rate de alterações biomecânicas em indivíduos com dor femoropatelar (DFP) tem crescido recentemente. Justifica-se o estudo dessa variável pela sua relação com lesões degenerativas articulares de diversas articulações, principalmente do joelho. No entanto, poucos estudos foram realizados para entender a relação da loading rate de parâmetros globais, como a força vertical de reação do solo (FVRS), com a DFP. Além disso, não foram encontrados estudos que tenham investigado a loading rate de parâmetros específicos da articulação do joelho que estão relacionados com a DFP, como o momento abdutor do joelho (MAJ). Portanto, os objetivos gerais dessa dissertação foram investigar a relação da loading rate de parâmetros globais e locais com a DFP. A coleta dos dados biomecânicos foi feita durante os gestos de subida e descida escada, antes e após a aplicação de um protocolo de sobrecarga. Esse protocolo consistiu de 15 subidas e descidas de escada com 35% do peso corporal alocado em uma mochila e com ritmo demarcado por um metrônomo (96 degraus/min). A dor auto-reportada das participantes também foi obtida tanto antes quanto após o protocolo de sobrecarga. Também foi solicitado que as participantes reportassem a dor referente ao mês anterior. No geral, nossos resultados mostraram relação entre a loading rate da FVRS e do MAJ com a DFP. Portanto, intervenções específicas devem ser aplicadas nessa população com o intuito de corrigir essas alterações e, consequentemente, diminuir a dor. / The study of the loading rate of biomechanical alterations in individuals with patellofemoral pain (PFP) has increased recently. One justify the study of this variable because of its relation with articular degenerative injuries, mainly at the knee. However, few studies have been done to understand the relation between the loading rate of the vertical ground reaction force (VGRF) and PFP. In addition, no studies were found in order to investigate the loading rate of specific parameters at the knee joint that are related to the PFP, such as the knee abductor moment (KAM). Therefore, the aims of this dissertation were to investigate the relation between the loading rate of local and global parameters with PFP. Data collection was performed during stair ascent and descent , before and after a loading protocol. The protocol consisted of 15 stair ascent and descent trials with 35% of the body weight allocated in a backpack. The rhythm was controlled by a metronome at 96 steps/min. Self-reported pain was obtained before and after the loading protocol. The average pain level at the last month was also obtained before data collection. In general, our results showed a relation between the loading rate of the VGRF and KAM with PFP. Therefore, interventions should be applied in order to correct these alterations and, consequently, decrease pain. / FAPESP: 2015/00406-2
