Balancing on the BACK

Dynamic Balance as Measured by the Y-Balance Test Is Reduced in Individuals with Low Back Pain: A Cross-Sectional Comparative Study

Hooper, Troy L., C. Roger James, Jean-Michel Brismée, Toby J. Rogers, Kerry K. Gilbert, Kevin L. Browne, and Phillip S. Sizer. Physical Therapy in Sport. 2016 22:.29–34. http://dx.doi.org/10.1016/j.ptsp.2016.04.006

Take Home Message: Patients who suffer from current or previous symptoms of lower back pain demonstrated lower reach distances in the posterior directions of the Y-Balance Test compared to healthy individuals.

Many patients suffering from low back pain (LBP) have postural control deficits, and patients who suffer from one episode of LBP are also more likely to suffer recurrent episodes. However, little is known if there are postural control deficits in patients who are in remission from LBP. Therefore, Hooper et al evaluated 42 participants (separated into 3, 14 patient groups; 8 males and 6 females per group) to compare patients with current LBP, those with a history of LBP, and healthy controls to their performance on the Y-Balance Test to establish relationships between Y-Balance Test performance, demographic, behavior, and disability measures.

Ethics of genetic testing and research in sport: a position statement from the Australian Institute of Sport.

Vlahovich N, Fricker PA, Brown MA, Hughes D. Br J Sports Med. 2016 Nov 29. pii: bjsports-2016-096661. doi: 10.1136/bjsports-2016-096661. [Epub ahead of print]

“The Australian Institute of Sport (AIS) has developed this position statement to address the implications of recent advances in the field of genetics and the ramifications for the health and well-being of athletes”. Key sections are “Genetics Testing for Health-Related Purposes”, “Involvement of Athletes in Genetic or Genomic Research”, “Genetic Research and Gene Doping”, “Ethics of Genetic Research and Testing Targeting Talent Identification”, and “Ethics of Genetic Research and Testing in Relation to Injury”. The document includes a box summarizing the positions adopted by the AIS on genetic research and testing athletes.

Thinking about high-dose vitamin D supplements for your athletes? Make sure the dose is right.

Efficacy of high dose vitamin D supplements for elite athletes

Owens DJ, Tang CY, Bradley WJ, Sparks A, Fraser WD, Morton JP, and Close GL. Med Sci Sports Exerc. 2016. [Epub Ahead of Print].
https://www.ncbi.nlm.nih.gov/pubmed/27741217                                                                                                     
Take Home Message: A Blanket high dose vitamin D supplement plan results in elevated levels of vitamin D metabolites after the supplementation is completed. This could result in lower than normal levels of vitamin D, which is the opposite effect of the intended supplementation.

Vitamin D is a necessary nutrient in all individuals, especially the physically active population, and has been shown to be influential in muscle development and repair among other benefits. Many athletes consume large supplemental doses of vitamin D for these reasons; however, the long-term effects of this are not well understood. Therefore, Owens and colleagues completed a repeated measures study with 42 elite male athletes to identify the responses of the body to both a moderate and high dose of supplemental vitamin D.

Physical Inactivity and Body Fatness May Influence the Association Between Sarcopenia And Osteoporosis

Body Fat and Physical Activity Modulate the Association Between Sarcopenia and Osteoporosis in Elderly Korean Women

Lee I, Cho J, Ji Y, Ha C, Kim T, & Kang H; Journal of Sports Science and Medicine. 2016, 15: 477-482.

Take Home Message: Increased body fat and physical inactivity may be modifiable risk factors for osteoporosis and sarcopenia.

Sports medicine clinicians are obligated to educate young patients about maintaining long-term wellness and promoting physical activity among all patients. Sarcopenia, or the loss of muscle mass, may lead to greater chance of falls in the aging population. This is of special concern because this population’s high risk of osteoporosis, which causes frail bones. Modifiable factors, such as physical inactivity, may influence the association between sarcopenia and osteoporosis but there is a need to further explore this possibility. Therefore, the authors aimed to: (1) determine the association between sarcopenia and osteoporosis in Korean women 65 years and older, and (2) determine if body fatness and physical activity modulate the association between sarcopenia and osteoporosis among aging, Korean women.

Is Normative Data the New Normal?

Normative Values of the Sport Concussion Assessment Tool (SCAT3) in High School Athletes

Snedden TR, Brooks MA, Hetzel S, McGuine T. Clinical Journal of Sports Medicine. 2016: Sep.

Take Home Message: Individual differences may be seen in baseline SCAT3 data between sex, history of concussion, and history of comorbidities. Therefore, using the patient’s personal medical history may add value to the SCAT3 sideline screening.

One of the most common assessment tools utilized to screen for a concussion is the sport concussion assessment tool (SCAT). Previous authors established that baseline testing utilizing the SCAT2 version found scores varied depending on specific modifying factors (age, sex, concussion history). The updated SCAT3 was released; however, there has been little research done to establish if these modifying factors exist in the current version. Therefore, the authors evaluated baseline SCAT3 scores from 750 healthy, nonconcussed high school athletes from 7 Wisconsin high schools (571 male; ~15 years of age) to establish normative data to account for sex, age and concussion history differences.

Neurological or Mechanical – Cross-over Effects of Foam Rolling on Ankle Dorsiflexion

Specific and cross-over effects of foam rolling on ankle dorsiflexion range of motion

Kelly S. Beardsley C. International Journal of Sports Physical Therapy. 2011, 11(4); 544-551.

Take Home Message: Foam rolling may lead to small improvements in dorsiflexion range of motion in the contralateral limb.

Flexibility training is a typical recommendation for healthcare professionals and strength coaches. Static stretching has a cross-over effect to the contralateral limb but it is unclear if foam rolling elicits the same effect. Therefore, the authors conducted a randomized trial to examine mechanical effects and neurological cross-over effects of foam rolling on dorsiflexion among 26 recreationally active college students (16 male and 10 female). Participants were randomly assigned to either a foam rolling group (13 participants) or control group (13 participants).

National Athletic Trainers' Association Position Statement: Preventing and Managing Sport-Related Dental and Oral Injuries

National Athletic Trainers' Association Position Statement: Preventing and Managing Sport-Related Dental and Oral Injuries

Gould TE, Piland SG, Caswell SV, Ranalli D, Mills S, Ferrara MS, Courson R. J Athl Train. 2016 Nov 22. [Epub ahead of print]

The National Athletic Trainers’ Association has released a position statement on preventing and managing sports-related dental and oral injuries.  The statement has recommendations regarding planning considerations; education; dental and oral injury classification and acute care; mouthguard effectiveness; and mouthguard material, fabrication, and care considerations. The authors also included a literature review and suggested best practices.
