EDITORIAL

Hello, And so another year is drawing to a close with this our final bulletin for 2019. It has been a big year for our group with the changing of the guard from Hamish to myself, and there is plenty of work to get through with the change to PNZ unified model in our sights in 2019. As a SIG we are proud to announce that we finished this year with 1015 members, which as far as we know is the first time in history that a PNZ SIG has had over 1000 members. So thank you to our members for being part of SEPNZ. Its been another busy couple of months for our executive with our face to face meeting in early November at the Trinity Hotel in Tauranga to check out the venue and prepare for the biannual symposium in March. Justin and I also attended the PNZ leadership day in late November which was a great chance to meet up with the other SIG's, branches and PNZ executive. We are excited to see the role out of the practitioner side of the PNZ website and the new market campaign if you haven't seen it "Don't say oh, say physio". The last bulletin we ran the photo competition for the cover of BJSM and although there wasn't a huge timeline to get entries in, we did receive 12 entries and we will be announcing the winner of this shortly. In this issue, we focus on and celebrate our students and their enthusiasm for our profession. This bulletin brings together a mix of our new graduates, and postgraduate students to show that life long learning is alive and well in our profession. Rebecca Peace a postgraduate student for Otago University contributes to this bulletin with her literature review of the use of cold-water immersion as a recovery strategy in rugby union and she comments on the most beneficial protocol to use with this population. Rebecca Blyth is currently working towards Masters of Sports Physiotherapy at the University of Otago, and her review explores the research behind adductor strengthening for the prevention of groin injuries in footballers with some clinical exercises which would be of benefit to your football players.

Last week Bharat, Justin and Michael from the SEPNZ executive attended the AUT student prize giving for the 4th Year students to award the SEPNZ prize for the best individual contribution in the fields of sports, exercise and recreation to Matthew Weir. Congratulations Matthew! We never stop learning and every 6 months we offer up the ASICS Education Fund. In August Tom Adams, as part of his PhD at AUT, received this award to assist in his research in shoulder instability. Well done Tom we look forward to your upcoming thesis. The next round for this grant closes in March 2019. Pip Sail adds an article review on the risk factors for, and prevention of, shoulder injuries in overhead sports. Also, there is an interesting App review from Justin Lopes. I am unsure of its clinical relevance, however, it's a handy app to have and can be used in many different contexts, so it's worth exploring. For some, this time of the year is used to reflect and make a plan for the year ahead and for others it is just surviving the Christmas parties and getting on holiday with family and friends. From all on the SEPNZ executive, we wish a safe and Merry Christmas and we hope that your plans include a possible trip to Tauranga for our symposium in March. The majority of our program and speakers are confirmed. Please be aware that the early bird rate closes at the end of January for this, for more information please check out our website for the up to date agenda and booking information. Enjoy your summer, and see you in 2019 in Tauranga. Noho ora mai

Kind Regards Blair Jarratt SEPNZ President

GET TO KNOW THE TEAM - 2 MINUTES WITH...

Blair Jarratt SEPNZ President

What role do you play on the exec? President – I took over this role from Hamish Ashton this year. I started on the executive 5 years ago helping to work on the sports physiotherapy contract that members can download in our resources section of the website and later looked after the website. Life outside of SEPNZ? My wife Sheree and I have two children - Ashton aged 9 and Pippa aged 7 and we live in Tauranga. I am the codirector of Bureta Physiotherapy in Tauranga with 18 staff, at this time of the year on the weekends the family will be at the beach. All year and when I have some time (usually ridiculously early in the mornings) you will find me out on the mountain bike as we have a pretty good bunch of riders here in Tauranga that get out 3 times a week. Previous teams worked with / sporting background....and present? I cut my teeth on sports physiotherapy pretty early on in the piece starting off when I was a Otago student with University Rugby, then more stints in Rugby in Canterbury working with High School Old boys, Sydenham, Canterbury Metro, and finally into Canterbury Rugby. Also while in Canterbury I worked with Canterbury Cricket, and the Canterbury Wizards for a number of years. I toured with NZ U19 Cricket to Australia and then onto the U19 world cup in Dubai. Currently I work with the Mount Surf Life Saving Club who are currently in full swing for the season and also help out with our staff that work with some of the Bay of Plenty's top rugby club’s - Mount Maunganui Rugby and Te Puna Rugby Favourite tune on a roadtrip? Most of the road trip tunes are pretty dominated by the kids around this time of year, Pippa is pretty relentless at pumping the Christmas carols, however I try to slip a few Dad tunes in. I am enjoying the new rendition of “Africa" by Weezer. Favourite sporting physiotherapy moment? Wow….. tough question I’m not sure I have a favourite moment, being part of a winning team is always exciting but in sport there is always winning and losing and good things to take away from both. Working in the management of a team and helping getting players back into what they love doing after significant set backs and injuries is always rewarding. Favourite/best or worst destination as touring Physio and why?

.

Working in Forsyth Barr Dunedin stadium for the Canterbury and Otago Rugby final was a pleasure as it was pouring down outside but Dubai was a eye opener for a place to Tour.

Abstract:

To assess the evidence for risk factors and prevention measures for shoulder injuries and the effect

of primary shoulder injury prevention measures in overhead sports by systemic review.

Shoulder injuries and shoulder pain are substantial problems in overhead athletes. This problem highlights the need for injury prevention strategies. Identifying risk factors and developing injury prevention strategies based on these risk factors are key components for preventing injury in sport. A common feature of overhead sports is the repetitive use of the shoulder with the hand above the head. There may be sex and age differences as observed in other anatomical sites in other sports8,18,19 and contact sports may be at higher risk. Biomechanical factors such as shoulder mobility, coordination and poor technique may also be factors. Overhead sport is defined as a sport in which the athlete, with the forearm/hand , repetitively propels a ball or shuttle against an opponent. The principle findings from the systematic review were that the studies were of poor quality, the results were inconsistent and most risk factors had only been explored in one study. Investigating modifiable risk factors, such as biomechanical, physiological,

and

modifiable training factors is required to develop successful injury prevention measures. This asks the question whether practitioners should be considering performance and return to play parameters rather than an injury prevention perspective.

Since there is little evidence to suggest that shoulder screening for injury prevention is effective79 the main purpose should be to evaluate current shoulder status, measure improvements in performance and serve as normative values to attain before return to play after injury.79-81 When the evidence is limited look for position statements and expert panel opinions.77

Conclusions: All investigated risk factors for shoulder injury in overhead ports had limited evidence, and most were non-modifiable (eg,sex). There is also limited evidence for the effect of shoulder injury prevention measures in overhead sports.

Does an ADDUCTOR STRENGTHENING PROGRAMME INCREASE adductor strength PREVENT adductor-related groin injuries in football?

By Rebecca Blyth (Masters of Sports Physiotherapy Student, Otago University)

Groin injuries are

one of the most prevalent injuries in football accounting for 8-18% of all injuries (Esteve,

Rathleff, Bagur-Calafat, Urrútia, & Thorborg, 2015; Serner et al., 2014). Adductor injuries account for over 60% of groin injuries, resulting in adductor injuries being the second most common injury in football (Ishøi et al., 2016; Jensen et al., 2014). Preventing adductor injuries is crucial in football not only because of the high incidence but also due to the time-loss associated with the injury; 40% of adductor injuries experience more than 28 days absence from football (Ishøi et al., 2016). Several studies have suggested that along with previous adductor injuries and increased age, reduced adductor strength is a risk factor for sustaining an adductor injury while playing football (Engebretsen, Myklebust, Holme, Engebretsen, & Bahr, 2010; Esteve et al., 2015; Ryan, DeBurca, & Mc Creesh, 2014). It has been well documented that specific adductor strengthening programmes show an increase in adductor strength, with increased eccentric strength being of particular importance (Harøy et al., 2017; Ishøi et al., 2016; Jensen et al., 2014). There is conflicting evidence surrounding whether the increase in adductor strength relates to a reduced injury risk. The aim of this critical review is to review the risk factors for adductor injuries, to review if adductor strengthening programmes increase adductor strength and explore if increased adductor strength reduces adductor-related groin injuries in football.

Risk Factors Risk factors for adductor injury can be either nonmodifiable or modifiable. The two most significant nonmodifiable risk factors in predicting adductor injury are a previous adductor injury and increased age (Arnason et al., 2004; Engebretsen et al., 2010; Ryan et al., 2014).

Adductor Strengthening Programmes Adductor strengthening programmes have been suggested as a solution to reducing groin injuries as they aim to strengthen the hip adductor muscle group. As football involves eccentric adductor strength during kicking, there has been suggestion that eccentric adduction weakness should be targeted in football injury prevention programmes (Ishøi et al., 2016; Jensen et al., 2014; Thorborg et al., 2014). A study comparing elite football players to matched recreational athletes showed that football players had increased eccentric hip abduction strength, however there was no significant difference in eccentric hip adduction strength (Thorborg, Couppé, Petersen, Magnusson, & Hölmich, 2011). This was a surprising result, but suggests that playing football does not induce eccentric hip adductor strength increases and therefore this is an area that needs to be targeted in off-field training (Thorborg et al., 2011). There has been good success in using eccentric exercises to reduce hamstring injuries in football (Al Attar, Soomro, Sinclair, Pappas, & Sanders, 2017) but the success of similar eccentric programmes in adductor injuries have not been so extensively researched.

The adductor longus tendon complex is put under high levels of eccentric stress during football, particularly while kicking (Jensen et al., 2014). Decreased eccentric adductor longus strength may compromise the energy absorption of the tendon and leave it more vulnerable to injury with increased stress at the adductor longus insertion (Thorborg et al., 2014).

Introduction With the ever increasing demands of competition scheduling and training loads in team sports such as rugby union, research into optimal recovery strategies is continuing to evolve (Tavares, Smith, & Driller, 2017). One such recovery method is the use of cold-water immersion or ice baths. Cold-water immersion therapy (a form of cryotherapy) by definition is the application of ice or extreme cold to the body to treat injury and/or aid a rugby athlete’s return to sporting performance (Higgins, Cameron, & Climstein, 2013; Stephens et al., 2018). The aim of this literature review is to investigate the current evidence regarding cold-water immersion as a method of performance recovery by means of its physiological effects and best application technique in rugby union.

Clinical application To apply the evidence to practice in the rugby environment, as shown above, several factors need to be taken into account. Firstly, what is the reason for trying to hasten the athlete’s recovery of performance? What beneficial effect needs to be gained from recovery? Is there concern over muscle power loss or development of delayed onset muscle soreness? What are the individual athlete’s rugby sporting demands and how might their body composition contribute? Taking all of these questions and the current best evidence into account, cold-water immersion should, in theory, have positive physiological and psychological effects. Out of the studies included in this review, the most beneficial protocol for application of cold-water immersion seems to be 2x5 minute intervals with a 2.5 minute break of immersion to the level of the superior iliac spine in 10-12°C water. If a rugby athlete reports perceived performance enhancements with the use of cold-water immersion, we should not rule it out as a beneficial technique for aiding recovery. To date, the research has not been able to define the most effective balance of temperature, time and technique to ensure cold-water immersion is beneficial for every rugby athlete’s recovery.
