The Effects of Self-Myofascial Release on Hamstring and Gastrocnemius Muscles Using Foam Roll on Postural Sway, Knee Proprioception, and Dynamic Balance in Recreationally Active Females

Mahdis Dadfar and Foad Seidi

Poor joint proprioception and balance maintenance may lead to sports injuries. Numerous studies have indicated that self-myofascial release (SMR) can improve the function of the proprioception and balance systems. Thus, this study aimed to investigate the effects of acute bouts of SMR on the center of pressure displacements during four stance positions, knee joint position sense at 45° and 90° in open kinetic chain tasks, and dynamic balance during the Y-balance test. Forty-two recreationally active females aged 20–25 years were assigned to either the foam roll group performing 1 min × 3 sets of SMR in the posttest session (N = 22) or the control group (N = 20). Joint position sense at 90° (p = .021), dynamic balance in the anterior (p = .007) and posterolateral (p < .001) directions, as well as the composite score (p = .001), improved significantly in the foam roll group. According to the findings, SMR may improve knee joint position sense at 90° and dynamic balance without any significant impacts on postural sway.

Randomized Controlled Trial Comparing Fibular Versus Talocrural Mobilization With Movement in Individuals With Chronic Ankle Instability

Cynthia J. Wright

Talocrural mobilization with movement (MWM) and fibular MWM are ankle joint mobilization techniques which may treat deficits in ankle dorsiflexion range of motion (DFROM) and balance in individuals with chronic ankle instability (CAI). The purpose of this study was to compare the acute effect of fibular MWM versus talocrural MWM in individuals with CAI. Thirty-nine individuals with CAI were enrolled and randomized to intervention (fibular MWM, talocrural MWM, or control). Baseline DFROM, inversion range of motion, and balance were assessed pre- and postintervention. Only the talocrural MWM group significantly increased DFROM postintervention. There were no significant group differences in inversion range of motion or balance. The results support the use of talocrural MWM, but not fibular MWM, to acutely improve DFROM in individuals with CAI.

Retention of Athletic Trainers in the Secondary School Setting

Kristen Couper Schellhase, Emily Tran, Shannon Carmody, Peter Dawry, and L. Colby Mangum

Research has explored factors related to retention of athletic trainers in collegiate settings but less is known about retention of athletic trainers in secondary school settings. This study aimed to investigate factors that increase retention of secondary school athletic trainers. Twenty-two secondary school athletic trainers (10 females and 12 males, length of employment 14.65 ± 5.01 years) participated in a semistructured video call interview with seven open-ended questions. A phenomenological approach revealed three themes and eight subthemes: (a) support (administration, partner athletic trainer, and non-work-related); (b) connections (impact on patients, school community, and wider community); and (c) security (financial and nonfinancial). Although participants acknowledged challenges, they identified aspects that positively influenced their retention.

Comparison of Support Provided by Prophylactic Athletic Tape Following Exposure to Moisture and Exercise

Meredith K. Owen, Julia A. Gambill, Jerome Razayeski, William C. Bridges, Cristina M. Acevedo, Naomi A. Wolhar, and John D. DesJardins

Prophylactic athletic tape is often used to provide additional ankle support and reduce potential injury in both wet and dry environments. The purpose of this study is to determine the effect of prophylactic athletic tape on ankle range of motion following exposure to moisture and exercise. Following exercise, range of motion increased slightly but remained below baseline and postexercise control values for all tape conditions. The novel synthetic tape maintained greater ankle support following the exercise period for wet condition in inversion and eversion. Cotton and novel synthetic adhesive tapes provided improved ankle stability following exercise, whether wet or dry, as compared with the use of no tape.

Memory Impairments Associated With Mild Traumatic Brain Injury: A Critically Appraised Topic

Karlee Burns, Leah Sanford, Ryan Tierney, and Jane McDevitt

Clinical Question: Do sports-related mild traumatic brain injury in adolescents and young adults produce changes that can be identified with functional magnetic resonance imaging that are associated with memory impairment? Clinical Bottom Line: After sport-related mild traumatic brain injury, functional magnetic resonance imaging identified inconsistent structural changes (e.g., cortical thickness changes, brain activation patterns), and negative performance changes in memory function (e.g., lower neuropsychological scores) in adolescents and young adults 9 days to more than a year following injury.

Fibular Glide Mobilization With Movement for the Treatment of Acute Lateral Ankle Sprains: A Critically Appraised Topic

Robert J. Bonser, Bethany L. Hansberger, Rick A. Loutsch, Christy L. Gendron, and Russell T. Baker

What are the effects of the Mulligan Concept™ posterior fibular mobilization with movement (MWM) on clinical outcomes in patients who sustain an acute lateral ankle sprain (LAS)? The evidence reviewed was level C–Recommendation based on “consensus, usual practice, opinion, disease-oriented evidence, or case series for studies of diagnosis, treatment, prevention or screening.” In the studies examined, patients who received Mulligan Concept™ posterior fibular mobilizations in combination with other treatments significantly improved (Minimal Clinically Important Difference met) on the Numeric Rating Scale (NRS) and Disablement of Physically Active (DPA) scale. All patients in the studies were discharged within 2-18 days. However, due to the low level of evidence and the use of traditional conservative treatments in conjunction with mobilization, it is difficult to ascertain whether the Mulligan LAS treatment aided recovery more than traditional methods of treating acute LAS. Therefore, Mulligan Concept™ posterior fibular MWM may be useful clinically in conjunction with traditional conservative treatments for reduction of pain, disability and discharge time for patients with acute LAS, but future research must be conducted to determine if MWMs offer any benefits above and beyond traditional methods of treatment.

Injuries in Masters Field Hockey Players Competing in the 2018 World Cup: Comparisons of Prevalence, Location, and Type by Age, Sex, and Field Hockey Experience

Karen Croteau, Nina B. Eduljee, Laurie Murphy, and John Rosene

This study examined prevalence, body location, and type of injuries reported by Masters Field Hockey players competing in the 2018 Masters and Grand Masters Field Hockey World Cups. There were 465 participants (284 females and 181 males) from 21 countries, ranging in age from 35 to 76 years. Participants completed The Health and Well-being of Masters Field Hockey Athletes Survey, which included injury type and location. The lower leg was the most common injury location and muscle strain the most common type of injury. Significant differences were found between females and males in upper extremity injuries and contusions.
