Review Meta Analysis
Can ultrasound imaging predict the development of Achilles and patellar tendinopathy? A systematic review and meta-analysis.
Ultrasound (US) imaging is commonly used to visualise tendon structure. It is not clear whether the presence of structural abnormalities in asymptomatic tendons predicts the development of future tendon symptoms in the Achilles or patellar tendon. ⋯ Identification of at-risk athletes using screening tools such as US may allow preventative programmes to be implemented. However, it is clear that other factors beyond tissue structure are involved in the development of lower limb tendinopathy.

Observational Study
Injuries in women's international ice hockey: an 8-year study of the World Championship tournaments and Olympic Winter Games.
We report the incidence, type, mechanism and severity of ice hockey injuries in women's international ice hockey championships. ⋯ The risk of injury to female ice hockey players at World Championship and Olympic tournaments was about half of that observed in the men's Championships. Full facial protection decreases the risk of lacerations and should be continued in all future female tournaments. More effective prevention strategies for knee, ankle and shoulder injuries are needed in women's ice hockey. Improved concussion education is necessary to promote more consistent diagnosis and return to play protocols.

Randomized Controlled Trial
Analysis of head impact exposure and brain microstructure response in a season-long application of a jugular vein compression collar: a prospective, neuroimaging investigation in American football.
Historical approaches to protect the brain from outside the skull (eg, helmets and mouthpieces) have been ineffective in reducing internal injury to the brain that arises from energy absorption during sports-related collisions. We aimed to evaluate the effects of a neck collar, which applies gentle bilateral jugular vein compression, resulting in cerebral venous engorgement to reduce head impact energy absorption during collision. Specifically, we investigated the effect of collar wearing during head impact exposure on brain microstructure integrity following a competitive high school American football season. ⋯ Reduced WM diffusivity alteration was noted in participants wearing a neck collar after a season of competitive football. Collar wearing may have provided a protective effect against brain microstructural changes after repetitive head impacts.

Randomized Controlled Trial Comparative Study
Effectiveness of footwear and foot orthoses for calcaneal apophysitis: a 12-month factorial randomised trial.
Calcaneal apophysitis, is a relatively common cause of heel pain in children. Very few randomised studies have evaluated treatment options. This trial compared the effectiveness of currently employed treatment options for the relief of pain and disability associated with calcaneal apophysitis. ⋯ This trial indicates at the 2-month time point there is a relative advantage in the use of heel raises over prefabricated orthoses for the treatment for calcaneal apophysitis. At 12 months there was no relative advantage to any one of the investigated treatment choices over another. Therefore, if a physical impact is experienced for greater than 2 months, the selection of treatment choice may defer to clinical judgement, cost-minimisation and or patient preference.
