Welcome to our first Issue of the Clinical Journal of Sport Medicine in 2018. 

This year, we have a whole host of exciting sporting events to look forward to including the FIFA World Cup in Russia and the Winter Olympics in South Korea. From the perspective of our Journal readership, I’m pleased to say that there will be a wealth of Original Research coming your way this year. 

The topic of concussion in sport continues to be in the news, and research articles related to this will continue to feature strongly in the forthcoming year. 

Indeed, we kick off the New Year with our Lead article this month by Delaney and colleagues who sought to elucidate the reasons why Professional Footballers choose not to reveal their concussion symptoms during training and games. In this retrospective survey of 454 male professional football players in Canada, it was found that a significant proportion of players who believed that they had suffered a concussion during their previous season chose not to seek medical attention for this for various reasons, despite seemingly adequate education concerning the issue. Whilst this finding is perhaps not surprising given previous research suggesting the under-reporting of concussive events in many sports, it does highlight the fact that educational interventions do not always lead to a change in behaviour. 

On the same topic, a prospective randomized controlled trial by Leddy and colleagues examined the safety and prognostic utility of provocative exercise tests in acutely concussed adolescents. A total of 65 adolescents with sport-related concussion presenting within the first 10 days of injury were randomized to either a Buffalo Concussion Treadmill Test versus no testing to determine whether this intervention might cause a short-term increase in symptoms or lead to delayed recovery. The results in this study showed that there was no short-term increase in symptoms, nor evidence of delayed recovery in the exercise intervention group subjects compared with the control group. In addition, lower Heart Rate threshold on the first visit day was found to be strongly associated with a prolonged recovery time. 

Moving on to the age-old problem of delayed onset muscle soreness (DOMS), Xie and colleagues examined the efficacy of dynamic contract-relax stretching on DOMS in the calf muscles of healthy subjects. Three groups of 16 test subjects were exercised to exhaustion using bilateral resisted heel raise exercises, and were randomly allocated to three separate groups – a control group (no intervention), a dynamic contract-relax stretch group (DS) or a static stretching group (SS), with both intervention groups performing these exercises for 5 consecutive days following the initial provocative exercise. 
The findings showed no significant differences between the three groups, suggesting that there was no significant impact of either DS or SS in treating DOMS. 

Other Original Research topics this month include first-aid treatment for blisters, baseline SCAT3 score differences between individuals living with and without disability, and the use of ultrasound guidance in the efficacy of shock wave treatment for plantar fasciitis and calcific achilles tendinopathy. 

Our Critical Review article this Issue by Bolia and colleagues looks at the range of hip pathology, risk factors and clinical outcomes amongst artistic athletes from studies over the last twenty years. In this Systematic Review, 38 studies were included. Chondro-labral pathology was shown to be the most commonly reported finding amongst these studies, but risk factors for particular injuries were not well defined. The authors call for more prospective studies to assist in answering the questions posed. 

Here’s looking forward to an exciting New Year. Don’t forget to check out our Social Media content at @CJSMonline and on the blog at https://cjsmblog.com
