Lower limb symposium
8 Lower limb symposium K. Paterson 1,2,∗ , J. Fuller 3 , J. Maharaj 4 , C. Bishop 5 1
Centre for Health, Exercise and Sports Medicine, The University of Melbourne, Australia 2 Lakeside Sports Medicine Centre, Australia 3 Faculty of Medicine and Health Sciences, Macquarie University, Australia 4 School of Human Movement and Nutrition Sciences, University of Queensland, Australia 5 University of South Australia, Australia This symposium will feature extended presentations from leading clinician researchers working in the field of lower limb biomechanics. Dr Kade Patterson from The University of Melbourne will talk about athletic footwear and knee health, with some very interesting (and important) insights arising from recent clinical trials performed at the Centre for Health and Exercise Medicine. Dr Joel Fuller from Macquarie University will present the longer term effects of minimalist running shoes on lower limb structure, function, running performance and injury. Jayishni Maharaj from The University of Queensland will present the findings from her PhD studies of the mechanical function of the subtalar joint and tibialis posterior muscle and tendon during gait. Dr Chris Bishop from the University of South Australia will discuss the findings from his recent research exploring the management of plantar heel pain and specifically, how the key is in the diagnosis. https://doi.org/10.1016/j.jsams.2017.09.197 9 The influence of foot biomechanics on knee function: Implications for foot-based interventions for common knee problems K. Paterson 1,2 1 Centre for Health, Exercise and Sports Medicine, The University of Melbourne, Australia 2 Lakeside Sports Medicine Centre, Australia
The knee is one of the most common regions for acute and chronic musculoskeletal injury. The complex biomechanical function of the foot is known to directly influence tibioand patellofemoral joint biomechanics associated with acute and 1440-2440/
chronic knee injuries. This in turn has led to the development of foot-based interventions, and footwear design modifications, designed to improve symptoms for a number of common knee problems. This presentation will review evidence of the association between foot biomechanics and knee function relevant to the development and progression of common knee injuries, such as patellofemoral pain and knee osteoarthritis. A brief discussion of the clinical implications for footwear design and other foot-based interventions for some of these knee problems will also be discussed. https://doi.org/10.1016/j.jsams.2017.09.198 10 The longer-term effects of minimalist running shoes on lower limb structure and function, running performance, and injury risk J. Fuller Faculty of Medicine and Health Sciences, Macquarie University, Australia The effects of transitioning to minimalist running shoes are a topic of interest for runners and scientists. However, relatively few studies have investigated longer-term effects of running in minimalist shoes. This paper will report preliminary findings from a planned 20-week follow-up of runners who participated in a 6-week randomised controlled trial of minimalist shoes and had successfully transitioned to using minimalist or control shoes for 35% of weekly training. Runners continued to transition to their allocated shoes throughout the planned 20-week follow-up by increasing minimalist or control shoe use by 5% each week. The allocated shoes were used for 100% of weekly running during the final 6 weeks of the follow-up. Training volume, shoe use, running-related pain and injury were monitored weekly. Time trial performance, running economy, stride rate, stride length, shoe comfort, ankle plantar flexor muscle strength, and bone mineral density in the tibia, calcaneus, and metatarsals were assessed at the end of the 20-week follow-up. Early published findings from this trial demonstrate that risk of sustaining a running-related injury increased for heavier runners using minimalist shoes compared to control shoes. Additionally, greater weekly calf, ankle, and shin pain severity were experienced by runners completing high weekly running distance using minimalist shoes compared to control shoes. This paper will expand on these published findings by (1) discussing
