Evaluation of the Zachery Lystedt Law among female youth soccer players.
Despite recent increased awareness about sports concussions, few studies have evaluated the effect of concussion laws on concussion outcomes among young athletes. The purpose of our study was to evaluate the effect of the Washington State Zachery Lystedt Concussion Law on playing with concussion symptoms and being evaluated by a health care provider. ⋯ The majority of concussed female youth soccer players report playing with symptoms. Legislation mandating concussion education and evaluation prior to returning to play was not associated with an increase in concussion evaluations by health care providers.

The utility of the balance error scoring system for mild brain injury assessments in children and adolescents.
The Balance Error Scoring System (BESS) is widely recognized as an acceptable assessment of postural control for adult patients following a mild traumatic brain injury (mTBI) or concussion. However, the measurement properties of the BESS as a post-mTBI assessment test for younger patients are not well understood. The purpose of this study was to evaluate the utility of the BESS as a post-mTBI assessment test for children and adolescents aged 8 to 18 years through 2 investigations: (1) a retrospective medical records review of the relationship among age, BESS scores, and other common post-mTBI assessment tests; and (2) a prospective study comparing BESS scores for a cohort of children with a recent mTBI and BESS scores for a cohort of matched healthy peers. ⋯ However, the observed differences were not likely to be clinically meaningful. Cumulatively, evidence from the literature and the results of these studies indicate that the BESS may be limited for producing accurate assessments of younger athletes' post-mTBI postural control abilities. Future research recommendations include testing of modified versions of the BESS or other alternatives for post-mTBI postural control assessments with younger individuals.

Validation of musculoskeletal ultrasound to assess and quantify muscle glycogen content. A novel approach.
Glycogen storage is essential for exercise performance. The ability to assess muscle glycogen levels should be an important advantage for performance. However, skeletal muscle glycogen assessment has only been available and validated through muscle biopsy. We have developed a new methodology using high-frequency ultrasound to assess skeletal muscle glycogen content in a rapid, portable, and noninvasive way using MuscleSound (MuscleSound, LCC, Denver, CO) technology. ⋯ These results demonstrate that skeletal muscle glycogen can be measured quickly and noninvasively through high-frequency ultrasound using MuscleSound technology.

Pregabalin reduces opioid consumption and improves outcome in chronic pain patients undergoing total knee arthroplasty.
Recently, multimodal pain control has been used to manage postoperative pain in patients undergoing total knee arthroplasty (TKA). This approach combines numerous modalities, such as opioids, nonsteroidal anti-inflammatory drugs, local anesthetics, and acetaminophen, in an effort to reduce overall opioid consumption and also to provide better pain control. Gabapentinoids are a class of drugs that have been used as part of multimodal approach, and may be effective in patients who are previous users of chronic pain medication. The hypothesis of this study was that the addition of pregabalin reduces opioid consumption and/or improves pain after TKA, even in patients who are previous users of chronic pain medications. ⋯ Pregabalin in the context of multimodal pain management may be associated with reduced opioid consumption and other medical complications in patients undergoing TKA, including previous users of chronic pain medications.

ReviewThe effects of platelet-rich plasma in the treatment of large-joint osteoarthritis: a systematic review.
Osteoarthritis (OA) is a common and costly condition with both operative and nonoperative treatments available. Platelet-rich plasma (PRP) is emerging as a treatment option for a variety of musculoskeletal pathologies, including OA. ⋯ Platelet-rich plasma may be an effective treatment for knee OA. However, because of the low level of evidence, small sample sizes, and wide variability in treatment, no definitive recommendations can be made at this time.
