#1
Simon Lack, Bradley Neal, Danilo De Oliveira Silva, Christian Barton
Patellofemoral pain (PFP) is one of the most prevalent conditions within sports medicine, orthopaedic and general practice settings. Long-term treatment outcomes are poor, with estimates that more than 50% of people with the condition will report symptoms beyond 5 years following diagnosis. Additionally, emerging evidence indicates that PFP may be on a continuum with patellofemoral osteoarthritis. Consensus of world leading clinicians and academics highlights the potential benefit of delivering tailored interventions, specific to an individual's needs, to improve patient outcome...

INTRODUCTION: Hamstring injuries remain a significant burden in sports that involve high speed running. In elite male football, hamstring injury has repeatedly been identified as the most common noncontact injury, representing 12% of all injuries. As the incidence remains high, investigations are aimed at better understanding how to improve prevention efforts. Intrinsic risk factors such as strength have been investigated extensively in a cohort of professional football players; however, other intrinsic measures of neuromuscular function have not been studied in this cohort...

The anterior cruciate ligament reconstruction (ACLR) has become a very common surgical procedure. One of the main success indicators of the surgical procedure is the return to preinjury sporting level. In recent years, reconstructive techniques have been geared toward less morbidity and optimized ligaments process to speed up the recovery of sports activity. This study compares clinical and imaging data, to evaluate the timing of return to sport, of two populations undergoing ACLR using two different techniques: ACLR with hamstring maintaining tibial insertion (MHG) and an all-inside technique with complete hamstring detachment (DHG)...

The expert-novice approach is inappropriate for studying postural control in sport and dance when novices are completely unable to perform relevant postural tasks and experts cannot demonstrate specific skills on everyday postural tasks. We tested expertise-specific differences on 6 static everyday and 5 dynamic dance-like postural tasks of varying difficulty in 13 professional and 12 intermediate nonprofessional dancers. Results showed a clear expert advantage on sway area for dance-like postural tasks, but not for static everyday tasks...

Learning from motor errors that occur across different limbs is essential for effective tool use, sports training and rehabilitation. To probe the neural organization of error-driven learning across limbs, we asked whether learning opposing visuomotor mappings with the two arms would interfere. Young right-handers first adapted to opposite visuomotor rotations A and B with different arms, and were then re-exposed to A 24 hours later. We observed that re-learning of A was never faster, nor were initial errors smaller than prior A learning, which would be expected if there was no interference from B...
