Correcting Chronic Ankle Instability with Exercises

Corrective Exercises Improve Movement Efficiency and Sensorimotor Function but Not Fatigue Sensitivity in Chronic Ankle Instability Patients: A Randomized Controlled Trial

Bagherian S, Rahnama N, Wikstrom E. Clin J Sport Med. 2017;0:1-10.

Take Home Message: Eight weeks of corrective exercises enhanced movement efficiency, dynamic and static postural control, joint position sense, and self-reported function in a non-fatigued state; however, the protocol did little to mitigate the effects of fatigue on these measures.

Chronic ankle instability (CAI) is associated with feelings of “giving way” or bouts of instability, decreased self-reported quality of life, and lower levels of physical activity. Thus, clinicians need treatments, like the National Academy of Sports Medicine (NASM) corrective exercise protocol, that target sensory and motor components of ankle function. The authors examined the efficacy of the corrective exercise protocol on self-reported function (Foot and Ankle Ability Measure (FAAM) and FAAM-Sport Subscale), movement efficiency (double-limb squat (DLS), DLS with heel lift, single-limb squat), dynamic postural control (Star Excursion Balance Test), static postural control (eyes open and eyes closed balance), joint position sense, and fatigue sensitivity compared with a non-treatment control condition among males with CAI.

Ankle Joint Mobilizations: What are They Good for?

Clinical Benefits of Joint Mobilization on Ankle Sprains: A Systematic Review and Meta-Analysis

Weerasekara I, Osmotherly P, Snodgrass S, Marquez J, Zoete R, Rivett D. Archives of Physical Medicine and Rehabilitation. 2017;[Epub ahead of print] doi: 10.1016/j.apmr.2017.07.019

Take Home Message: Ankle joint mobilizations improve dynamic balance and weight-bearing dorsiflexion range of motion in patients with chronic ankle sprains.

Joint mobilizations are recommended for the management of a grade 1 or 2 lateral or medial ankle sprain. Current systematic reviews are limited as they include studies that did not evaluate the efficacy joint mobilizations in isolation, and rather as an adjunct to other interventions (e.g. rest, ice, compression, elevation). Moreover, these systematic reviews have a narrow focus on improving outcomes in patients with a lateral ankle sprain. Therefore, Weerasekara and colleagues undertook a systematic review and meta-analysis to synthesize the available literature examining the efficacy of joint mobilizations as a unique intervention in patients with a grade 1 or 2 lateral or medial ankle sprain during any stage of recovery (acute, subacute or chronic).

Career Ending Injuries May Be More Depressing Than We Thought

Associations between retirement reasons, chronic pain, athletic identity, and depressive symptoms among former professional footballers

Sanders G, Stevenson C. 2017; European Journal of Sport Science. ahead of print.

Take Home Message: A career-ending injury makes a professional athlete more likely to have depression symptoms during retirement. Experiencing chronic pain and maintaining a high sense of athletic identity also increase risk of depression.

Numerous factors increase the risk of depression following retirement from a professional sport. However, we often study each factor without considering the other factors, and little is known if athletic identify and retirement reasons are associated with depression later in life. Therefore, the authors examined relationships between career-ending injury, chronic pain, athletic identity, and depressive symptoms in 307 retired United Kingdom professional footballers (~47 years old).

European Association of Preventive Cardiology (EAPC) and European Association of Cardiovascular Imaging (EACVI) joint position statement: recommendations for the indication and interpretation of cardiovascular imaging in the evaluation of the athlete's heart.

European Association of Preventive Cardiology (EAPC) and European Association of Cardiovascular Imaging (EACVI) joint position statement: recommendations for the indication and interpretation of cardiovascular imaging in the evaluation of the athlete's heart.

Pelliccia A, Caselli S, Sharma S, Basso C, Bax JJ, Corrado D, D'Andrea A, D'Ascenzi F, Di Paolo FM, Edvardsen T, Gati S, Galderisi M, Heidbuchel H, Nchimi A, Nieman K, Papadakis M, Pisicchio C, Schmied C, Popescu BA, Habib G, Grobbee D, Lancellotti P. Eur Heart J. 2017 Sep 23. doi: 10.1093/eurheartj/ehx532. [Epub ahead of print]

The European Association of Preventive Cardiology (EAPC) and European Association of Cardiovascular Imaging (EACVI) have released a joint position statement on the recommendations for the indication and interpretation of cardiovascular imaging in the evaluation of the athlete's heart. The goal was “to properly address the determinants of cardiac remodelling, indications for imaging and clues for differential diagnosis with cardiac pathology.” They also address a “number of pathologic conditions that are relevant to the cardiovascular evaluation of the athletes (and were not included in previous document), such as left-ventricular non-compaction, myocarditis, mitral valve prolapse, and bicuspid aortic valve”.

We Are (Not Helping) the Youth of Our ACL Nation

Young Athletes After Anterior Cruciate Ligament Reconstruction Cleared for Sports Participation: How Many Actually Meet Recommended Return-to-Sport Criteria Cutoffs?

Toole AR, Ithurburn MP, Rauh MJ, Hewett TE, Paterno MV, & Schmitt LC. J Orthop Sports Phys Ther. 2017; Online Ahead of Print October 26, 2017.  

Take Home Message: Most athletes are NOT meeting accepted clinical cutoffs for strength and functional testing prior to returning to sport after an ACL reconstruction.

It is recommended that clinicians use objective criteria to make return-to-play decisions for patients after an anterior cruciate ligament (ACL) reconstruction. It remains unclear how many athletes who are cleared to play meet suggested criteria and if those who meet the criteria are more successful in returning to pre-injury levels of activity.  Therefore, the authors investigated the proportion of athletes who met predefined criteria for strength, hop testing, and patient-reported outcomes and whether meeting the criteria made an athlete more likely to maintain their pre-injury level of physical activity/sport participation.

It’s not Just Happening in Hollywood, Rape Myths are Accepted on College Campuses

National Comparisons of Rape Myth Acceptance Predictors Between Nonathletic and Athletes From Multi-Institutional Settings

Navarro JC, Tewskbury R. 2017; Sexual Abuse. ahead of print.

Take Home Message: Both athletes and nonathletes report accepting some rape myths, and predictors about these rape myths are different for each group.

Rape myths are false beliefs about rape and those involved.  Athletes are commonly cited as perpetrators of sexual violence on college campuses; however, little is known if different demographic lifestyle and characteristics influence rape myth acceptance among athletes and nonathletes. Therefore, the authors surveyed 624 nonathletes and 101 athletes from 21 U.S. Division I institutions (16 different states) using the Illinois Rape Myth Acceptance Scale to gauge the level of endorsement of rape myths during the spring 2015 academic term.
