Patellar Tendon Structure in Volleyball Athletes with and without Anterior Knee Pain
by Kyle Harris in Sports Medicine Research (SMR): In the Lab & In the Field
Patellar tendinopathy is common in athletics, especially among volleyball players. The condition occurs due to degeneration and/or inflammation secondary to physical activity. Additionally, clinical imaging struggles to distinguish between inflammatory and degenerative conditions further complicating diagnosis and thus, management. Therefore, Kulig and colleagues sought to perform a detailed analysis of patellar tendon collagen bundle organization in elite male volleyball athletes.... Read more »

Football or Not…More Symptoms Equals More Time on the Bench
by Jane McDevitt in Sports Medicine Research (SMR): In the Lab & In the Field
Most athletes’ concussive symptoms are alleviated within 1 week; however, some athletes’ concussive symptoms may last longer. If we could identify risk factors for concussive symptoms that persists for over 1 week then this could lead to better evidence-based return-to-play policies since we could apply more cautious restrictions on patients with those risk factors. The purpose of this study was to determine the risk factors for concussive symptoms that persist for over 1 week among high school athletes. Additionally, the authors wanted to determine whether risk factors were different for football compared to other sports.... Read more »

Muscle-enhancing Behaviors among Adolescent Girls and Boys
by Mark Rice in Sports Medicine Research (SMR): In the Lab & In the Field
With the emphasis that is placed on sport and performance in today's society, there is no doubt that adolescents are engaging in muscle building behaviors. With the potential to earn a collegiate scholarship, it's also not out of the question that some of these adolescents might be looking to gain muscle and strength by pursuing less healthy means. In addition, socio-cultural factors may be impacting adolescents’ body image, forcing many young females to engage in muscle enhancing activities to promote leanness and muscle tone. However, it remains unknown which demographics are engaging in either the healthy or unhealthy tactics, and to what degree. Therefore, the purpose of this study was to examine the prevalence of five muscle building behaviors in male and female adolescents across various races, weight status, socio-economic status (measured by parents education level) and sport team involvement....

Post-surgical ACL Postural Control on Wii Balance Board
by Nicole Cattano in Sports Medicine Research (SMR): In the Lab & In the Field
Postural control may potentially be negatively affected well after anterior cruciate ligament (ACL) reconstruction surgery. The loss of mechanoreceptors within the original ACL may contribute to these deficits, along with many other possible factors (e.g., psychological, neuromuscular). The question remains whether postural control would further be affected while performing a secondary task, which would be more similar to when athletes return to activity post-surgery. Therefore, the purpose of this cross-sectional study was to evaluate postural control with and without a secondary task among patients with ACL reconstructions compared to matched controls....

Hyaluronic Acid vs PRP for Knee Osteoarthritis
by Kris Fayock in Sports Medicine Research (SMR): In the Lab & In the Field
Osteoarthritis (also known as gonarthrosis) is characterized by structural and biochemical changes throughout the entire joint. Unfortunately, osteoarthritis can be challenging to treat and no treatments have been demonstrated to slow, halt, or reverse osteoarthritis progression. Recently, it has been hypothesized that hyaluronic acid (HA), a key component of synovial fluid, or platelet-rich plasma (PRP), which contains various growth factors involved in the inflammatory/healing process, may be good therapies for osteoarthritis. Therefore, Cerza and colleagues conducted a randomized trial to compare the clinical responses to HA and PRP treatment in 2 groups of patients affected by knee osteoarthritis (Kellgren-Lawrence grades 1 – 3; mild-moderate disease)....

Clinical and Functional Tests to Diagnosis of Patellofemoral Pain Syndrome
by Kyle Harris in Sports Medicine Research (SMR): In the Lab & In the Field
Patellofemoral pain syndrome (PFPS) affects between 15 and 25% of the general population, and is more predominant in physically-active individuals. Although PFPS is prevalent in the active population, there is no “gold-standard” set of procedures for diagnosing PFPS. Therefore, Nunes and colleagues performed a systematic review to investigate the accuracy of clinical and functional tests used in diagnosing PFPS.... Read more »

Wii Pre-habilitation
by Nicole Cattano in Sports Medicine Research (SMR): In the Lab & In the Field
Measuring ground reaction and contact pressure forces can be a time-intensive and expensive burden that is often difficult to justify for clinical uses; for example, injury prevention or performance improvements among the athletic population. Recent technological advancements within video gaming systems and the development of the Wii balance board may make this type of analysis more readily available to clinicians and patients in sports medicine. Therefore, the purpose of this study was to investigate the validity of the Wii balance board in assessing ground reaction forces in comparison to a laboratory force plate.... Read more »

Hard to Make Connections after a Concussion?….Blame it on the Default-Mode Network
by Jane McDevitt in Sports Medicine Research (SMR): In the Lab & In the Field
The default-mode network comprises several brain regions (i.e., posterior cingulate cortex, inferior parietal and medial prefrontal cortex) and is involved in brain activity at rest. When this network is altered higher cognitive functions (e.g., memory) become disrupted. Similar dysfunctions are symptoms from a mild traumatic brain injury (MTBI). Therefore, Zhou and colleagues investigated the integrity of the default-mode network among 23 patients with MTBI and 18 healthy control participants.... Read more »

Limited Effectiveness of ACL Reconstruction with Remnant Preservation
by Kyle Harris in Sports Medicine Research (SMR): In the Lab & In the Field
Recent claims suggest that a surgical procedure, which uses the remnant of the ruptured anterior cruciate ligament (ACL), would be beneficial to the long-term outcome of patients with an ACL rupture. Therefore, Hong and colleagues completed a randomized controlled trial to compare the short-term clinical outcome of remnant-preservingACL reconstruction (ACLR) to the standard ACLR.... Read more »

Mom and Dad may Contribute to my Achilles Heel
by Jane McDevitt in Sports Medicine Research (SMR): In the Lab & In the Field
The risk of developing Achilles tendinopathy is strongly related to intrinsic factors such as an individual’s genes (genotype). Previous research has found that 2 genes, which encode proteins in the composition of tissue, may be associated to Achilles tendinopathy (COL5A1 and TNC). COL27A1 is another gene in close in proximity to both of those genes and provides instructions for a type of collagen. Therefore, the purpose of this study was to view the association between the risk of Achilles tendinopathy and several genetic variants (specifically, single nucleotide polymorphisms;SNPs), including COL27A1 and TNC genes....

Practice Injury Rates in Collegiate Sports
by Christian Glaser in Sports Medicine Research (SMR): In the Lab & In the Field
Understanding when injuries are more likely to occur (e.g., practice vs competition, preseason vs in-season) can help us optimize injury prevention programs. To date, research has hinted at evidence that practice injury rates may be higher during pre-season compared to other parts of the season but this has not been thoroughly investigated. Therefore, Agel and Schisel evaluated the differences in practice injury rates within a competitive season (preseason, in-season, postseason) and across 15 sports and college levels (NCAA Division I, II, and III)....

Kinesio taping Does Not Improve Gastrocnemius Muscle Function in Healthy, Active Individuals
by Kyle Harris in Sports Medicine Research (SMR): In the Lab & In the Field
Kinesio-tape (KT) has become increasingly popular in athletics. Theoretically, KT is used to lift the skin which will increase blood and lymphatic flow; therefore, improving muscle function. However, minimal research has been conducted to evaluate the effectiveness of KT for improving muscle function. Therefore, Stedge and colleagues conducted a randomized controlled clinical trial with 61 volunteers (23 men, 38 women, 19.9 ± 8 years old) to determine the effect of KT on the muscular endurance ratio, blood flow, and circumference and volume of the grastrocmenius muscle....

Wasted Effort or Useful Technique – What's The Truth About Scapular Repositioning and Muscle Activation
by Mark Rice in Sports Medicine Research (SMR): In the Lab & In the Field
Once generally overlooked, the role of the scapula has become the focus of many injury prevention and sports performance programs. In order to achieve neuromuscular control and dynamic stability, programs call for some level of conscious scapular neutral positioning prior to exercise. However, it is unclear if this affects the main scapular rotators (trapezius muscles) during loading. Therefore, the purpose of this study was to examine the effect of conscious scapular positioning on upper (UT), middle (MT) and lower trapezius (LT) activity during 4 loaded exercises performed by overhead athletes presenting with scapular dyskinesis....

Can Laser Therapy be used to Treat Meniscal Injuries?
by Nicole Cattano in Sports Medicine Research (SMR): In the Lab & In the Field
A meniscal injury is the most common cause of symptomatic knee pain. Due to the inability of the meniscus to heal, current management of these injuries involves symptomatic management, and surgery as needed. Low-level laser therapy (LLLT) for soft tissue injuries has become increasingly apparent in recent years, with claims of reduction in pain, inflammation, as well as accelerated healing time. It is currently being used for these possible benefits; however, its effectiveness for treating meniscal tears is still unknown. Therefore, the purpose of this double-blind placebo-controlled study was to assess the effectiveness of LLLT in 64 patients with symptomatic medial meniscus injuries. Half of the patients were randomized to receive LLLT and the other half was randomized to receive sham treatment.... Read more »
