Aiming for the STARS for Chronic Ankle Instability

Sensory-Targeted Ankle Rehabilitation Strategies for Chronic Ankle Instability

McKeon PO & Wikstrom EA. Med Sci Sports Exerc. Published Online First: December 10, 2015; DOI: 10.1249/MSS.0000000000000859

Take Home Message: Sensory-targeted rehabilitation strategies (STARS) result in improvements in patient-reported and clinical outcomes.  Certain deficits may be specifically targeted by different techniques.

Chronic ankle instability (CAI) with recurrent episodes of giving way and functional limitations can cause long-term complications.  Sensorimotor deficits may play a significant role in those with CAI.  Therefore, the authors of this randomized control study compared the effects of 3 sensory-targeted ankle rehabilitation strategies (STARS; i.e., ankle joint mobilization, plantar massage, or triceps surae stretching) on improvements in clinician- and patient-reported outcomes among individuals with CAI.

Should We Check the Checking Age in Youth Ice Hockey?

Incidence of Concussion in Youth Ice Hockey Players

Kontos AP, Elbin RJ, Sufrinko A, Dakan S, Bookwalter K, Price A, Meehan WP, Collins MW. Pediatrics. 2016;137(2):e20151633.

Take Home Message: Concussion rates in youth ice hockey are nearly 3 times higher during games compared to practice, and 12 to 14 year olds have higher incidence rates compared to 15 to 18 year olds.

Ice hockey is consistently one of the sports with the highest concussion incidence rates. Additionally, concussions represent a greater proportion of total injuries among boy’s ice hockey (22%) compared to other sports (13%).  However, much of this data are taken from only games. Therefore, the authors monitored 397 youth ice hockey players (12-18 years) during the 2012-13 and 2013-14 seasons for a total of 23,360 athletic exposures (AE; 12,784 practice & 10,585 game) to determine the incidence of concussion in relation to games versus practices and age.

Short on Treatment Time? Try a Single-Item Patient-Rated Outcome

The validity of single-item patient-rated outcomes in concussed adolescent football athletes

Valier AF, Bacon CAW, Bay C, Houston MN, McLeod TCV. Arch Phys Med Rehabil. 2015. [Epub Ahead of Print].

Take Home Message: Single-item patient-reported outcome measures are valid for assessing patient progress in adolescent football athletes with concussions.

Clinicians who treat patients with sports-related concussions often use patient-reported outcomes (PRO) to monitor a patient’s symptoms and guide treatment; however, PROs with multiple questions are often cumbersome and time-consuming. An alternative is a single-item PRO that could be easier for clinicians to implement, while still providing clinicians with valuable feedback. Therefore, Valier and colleagues completed a longitudinal study of high school athletes with a concussion to determine the validity of 3 single-item PROs over time (the global ratings of change [GROC], daily activities [GRODA], and athletic activities [GROAA]).

The American Chiropractic Board of Sports Physicians Position Statement on Pre-Participation Examinations: An Expert Consensus

The American Chiropractic Board of Sports Physicians Position Statement on Pre-Participation Examinations: An Expert Consensus.

Moreau WJ, Nabhan DC, Roecker C, Kimura MN, Klein A, Guimard B, Pierce K, Helma P, Nelson R, Bahr KS, Nelson L, Williams P. J Chiropr Med. 2015 Sep;14(3):176-82. doi: 10.1016/j.jcm.2015.08.004. Epub 2015 Nov 14.

The American Chiropractic Board of Sports Physicians (ACBSP) has released a “position statement of best practices for the provision of a safe and high-quality pre-participation examination (PPE) and to provide recommendations on education requirements for doctors of chiropractic providing the PPE.” After some introduction the document reviews the ACBSP’s positions on chiropractic PPE qualifications, PPE performance standards, general physical examination, and clearance for sport participation.

Australasian College of Sports Physicians-position statement: The Place of Mesenchymal Stem/Stromal Cell Therapies in Sport and Exercise Medicine

Australasian College of Sports Physicians-position statement: the place of mesenchymal stem/stromal cell therapies in sport and exercise medicine

Osborne H, Anderson L, Burt P, Young M, Gerrard D. Br J Sports Med. 2015 Dec 23. pii: bjsports-2015-095711. doi: 10.1136/bjsports-2015-095711. [Epub ahead of print]

The Australasian College of Sports Physicians have released a position statement that “outlines the use of mesenchymal stem cell (MSC) therapies in the broad context of Sport and Exercise Medicine, recognising that every medical practitioner should respect: (1) the evidence for the therapeutic use of MSCs and (2) the priority for patient health and welfare.” The document includes a narrative review of literature, including aspects regarding efficacy of ethical concerns. The Position Statement concludes with a comprehensive summary.

Helmetless Tackling Promotes Better Tackling Behaviors Resulting in Less Head Impacts

Early Results of a Helmetless-Tackling Intervention to Decrease Head Impacts in Football Players

Swartz EE, Broglio SP, Cook SB, Cantu RC, Ferrara MS, Guskiewicz KM, Myers JL. J Athl Train. 2015; ahead of print

Take Home Message: Helmetless-tackling training reduces head impacts in collegiate football players.

High school and college football athletes can experience more than 1000 head impacts in a single season. Multiple head impacts have been associated with brain injuries such as concussions and chronic traumatic encephalopathy. The researchers performed a randomized clinical trial to determine if a helmetless-tackling behavioral intervention could reduce the number of head impacts among athletes in a National Collegiate Athletic Association Division I football program.

Help Yourself Improve Dorsiflexion A Little More

Ankle-Dorsiflexion Range of Motion After Ankle Self-Stretching Using a Strap

Jeon I, Kwon O, Yi C, Cynn H, & Hwang U. J Athl Train. Published Online First: December 3, 2015; DOI: 10.4085/1062-6050-51.1.01

Take Home Message: A dynamic self-stretching technique may improve dorsiflexion even better than traditional self-stretching due to a strap that aids in gliding the talus posteriorly relative to the distal tibia to improve arthrokinematics.

Limited ankle dorsiflexion may contribute to many acute and chronic lower extremity pathologies (e.g., ligament tears, sprains, tendinitis, fasciitis).  Improvements in ankle dorsiflexion may aid in the reduction and/or prevention of these pathologies. The authors of this randomized controlled trial developed a novel self-stretching technique with a strap (SSS) that combines a weight-bearing stretch with a gliding motion at the talocrural joint.  The goal of their clinical trial was to compare the effects of a 3-week program using a traditional static stretch or SSS on change in ankle dorsiflexion among individuals with limited dorsiflexion.
