  • Rolfing---not. Structural Integration---yes

    The last paragraph cites Rolfing when it should be Structural Integration. There are many schools of Structural Integration of which Rolfing Structural Integration is one, Describe the modality as massage if you must, though I would prefer, "a form of manual therapy" or "a form of manual therapy that is often categorized as massage." I am surprised that this error passed through the editors and peer review.

  • “No, my first name ain’t ‘Biostatistician’. It’s ‘Epidemiologist’ (Dr. Kerr, if you’re nasty)”

    It is with great pleasure that I read the commentary by Casals and Finch on the role of the Sports Biostatistician in injury prevention (1). Thank you to the authors for considering this important area of focus. With that said, I hope my additional comments, despite being a relatively new Sports Injury Epidemiologist in the field (receiving my PhD in 2014), can continue the discussion and dialogue that the authors have generated since this publication.

    First, as noted above, I prefer to describe myself as a “Sports Injury Epidemiologist” and not the term Casals and Finch use (“Sports Biostatistician”). Casals and Finch are forthright in denoting that their term is not well known and includes “the combination of statistics and epidemiology and public health or medicine and sports science (1, p.1457). Still, I am hesitant to use this term myself as my training was in epidemiology and not in biostatistics (although the expectation is that I have a good working knowledge of the latter as much as the former). I would not feel comfortable using a term that describes a role for which I was not trained. And although I cannot express the opinion of my former advisor and mentor, Dr. Steve Marshall, I would believe that he would agree, particularly as his faculty webpage describes himself as an epidemiologist and not a biostatistician (2).

    The term “epidemiology” originates from 3 Latin roots - (1) epi (Latin for ‘‘on,’’ ‘‘upon,’’ and ‘‘against’’), (2) demos (‘‘pe...

  • Response to Phillip Page, correspondence 'Evidence for RICE in acute sprains?'

    Dear Phillip Page,
    Thank you for your compliments concerning our updated guideline. We would like to take the opportunity to respond to your feedback and the questions you raised.
    First, concerning RICE as a treatment modality and our recommendation in the guideline not to use RICE in the treatment of ankle sprains. Through our extended literature search we found insufficient evidence to support RICE as a treatment modality by itself based on reported effectiveness and therefore we could not include it as a recommendation. Despite its frequent use in daily clinical practice, especially in the acute setting, we did not find a beneficial effect of any of the individual aspects or RICE.[1-4] However, as you correctly point out, RICE in combination with other treatment modalities they seem to provide a beneficial effect to patients.[5, 6] The beneficial effect that can be measured when combining RICE clinically with other interventions such as exercise, may also derive from the other intervention. For this reason we assessed each treatment and prevention modality individually, in addition to an in-text discussion of articles that studied combined therapy.
    In your letter you mentioned that emphasis in our recommendation was missing that it concerned single therapy by adding the word ‘alone’. This is a keen observation, and even though we did use the word alone in our in-text recommendation we did not include it in our summary (table 8): “There is no evidence t...

  • Response to: We need to talk about manels: the problem of implicit gender bias in sport and exercise medicine

    Response to: We need to talk about manels: the problem of implicit gender bias in sport and exercise medicine

    A recent editorial in the British Journal of Sports Medicine asserted that the presence of implicit bias in Sport and Exercise Medicine (SEM) is negatively affecting women in the field.1 We are concerned with the editorial’s lack of scientific approach, poor standard of evidence, and exclusion of important facts.

    The editorial argued implicit bias results in pronounced real-world effects in the form of gendered differences in SEM and society as a whole. However, no substantial scientific evidence of the magnitude of implicit bias’s real-world consequences on gender differences was presented. Instead, circular reasoning was utilized as implicit bias was assumed to manifest the gendered differences present in the SEM field and society.

    Implicit bias has been criticised within its field of psychology. A recent meta-analysis found little evidence that measurements of implicit bias are associated with any real-world manifestations of explicit bias or behaviour.2 Indeed, Patrick Forscher, one of the study’s authors implied in an interview that implicit bias’ use in policy making could be wasteful and even harmful.3

    Research suggests gender has an influence on personality, career preferences, and priorities.4 Indeed, where more freedom is allowed, the greater the disparity in traditionally gendered sectors.5 Extrapolation of thes...

  • Author response to Boynton et al. [Response to: We need to talk about manels: the problem of implicit gender bias in sport and exercise medicine, 11 April 2018]

    We want to thank Boynton et al. for writing a letter to the editor (LTE) in response to our recent editorial on gender disparities in the sport and exercise medicine (SEM) community [1]. As the title of our editorial indicates [We need to talk about manels: the problem of implicit gender bias in sport and exercise medicine], we were primarily motivated to stimulate a conversation about the issues we raised, and an LTE contributes to this conversation [2].

    We were also motivated by a desire to assert that i) the SEM community does indeed manifest many examples of gender disparity; ii) social media has provided a space where this issue is being debated, notably (but not exclusively) under the hashtag #manels; iii) implicit bias is a significant contributor to these disparities, and iv) there exist well-established resources where interested readers might explore their own implicit biases [3].

    It is in these goals, then, that we fundamentally disagree with most of the assertions the LTE authors have made about our work and the conclusions they draw.

    We noted with interest that the authors of the LTE did not take direct issue with our assertion that there exist substantial gender imbalances within the field of SEM. Rather, they took issue with our assertion that implicit gender bias underpins these imbalances.

    We posit in our editorial that implicit bias is a factor contributing to the gender disparities we see in SEM. Discussing implicit bias in t...

  • Should a pregnancy test be required before scuba diving?

    In this letter the authors observe "a significant difference ..in the rate of offspring malformations between women who dive (6 children affected), and those who did not dive during their pregnancy (none had malformation, p<0.01). A rate of zero malformations in the non-diving population should immediately have alerted the authors to the fact that their survey was biased. In the UK population there is an approximate rate of malformation of 1 in 80 live births and I would think that the rate is similar in France. Instead of using 0 for the malformations the authors should have used the rate observed in the French population. The conclusion of the paper that pregnancy testing should be undertaken before each scuba diving session is not supported by these data.

  • The Ankle Roll Guard is a Tested & Effective Alternative to Braces & Tape for Lateral Ankle Support

    The Ankle Roll Guard (anklerollguard.com) is a patented & independently tested, brace-less ankle support that cushions the ankle from an inversion or “roll”. Unlike conventional ankle braces, it wraps securely around the outside of any shoe type and allows the user to retain full ankle mobility and comfort.
    - Patented outside shoe design allows user to retain ankle mobility & comfort while still having ankle protection (no ankle restriction like a brace)
    - Provides ankle stability & protection for users with chronic lateral ankle instability
    - Clinical, independent testing at Boise State University using a motion analysis system showed equivalent inversion protection plus better range of motion & vertical jump versus a brace or tape
    - Weighs only 2.4 ounces so users do not feel it

    Independent Testing at Boise State University
    White Paper Completed January, 2018:
    “Of all the devices (Ankle Roll Guard, Brace, Tape), only the Ankle Roll Guard appears to allow the user normal ankle motion (i.e. typical anatomical joint motion), while preventing excessive ankle inversion” 
    – Tyler Brown, PhD, CSCS, Director COBR
    ​Conclusion: The Ankle Roll Guard may provide similar prevention of excessive inversion as either the brace or tape, but without the mechanical restriction of the joint that reportedly limits physical performance when wearing ankle prophylactic devices.  With the Ankle Roll Guard, p...

  • Evidence for RICE in acute sprains?

    I congratulate the authors for such a well-rounded and informative update of this CPG. I was not surprised to see the conclusion in the text that the evidence is 'unclear' in the use of ice on acute ankle injuries. There simply are not enough well-controlled RCTs can support RICE's efficacy when used alone. Clinically, we always combine ice with other interventions such as exercise. Your recommendation in the text was, "There is no evidence that RICE alone, or cryotherapy, or compression therapy ALONE (emphasis added) has any positive influence on pain, swelling or patient function. Therefore, there is no role for RICE ALONE (emphasis added) in the treatment of acute LAS." Based on the evidence, I would agree with that statement. However, Table 8's "Final Recommendations" for RICE states, "RICE is not advised as treatment modality after a LAS." I would argue that the authors should have inserted the word, "ALONE" in this recommendation; otherwise, they are making a blanket conclusion that ice is NOT effective when in fact, the evidence remains unclear (there may be some benefit when used in conjunction with other treatments) and potential harmful effects were not discussed if that was part of the decision-making. Unfortunately, I was unable to find the meta-analysis data upon which these recommendations against RICE were made, as Supplement 3 did not include any analysis on RICE interventions. While I am not a...
