Context: This case study demonstrates the effectiveness of early surgical excision of the traumatic myositis ossificans of the vastus intermedius muscle in an elite football player and return to sports activity within 3 months from the initial injury. Case presentation: A 27-year-old male professional football player presented with progressive pain and loss of range of motion after sustaining a severe, right quadriceps contusion 4 weeks earlier. After unsuccessful conservative therapy, the differential diagnosis of myositis ossificans was suspected and confirmed on radiographic examination. MRI revealed significant edema encompassing a substantial portion of the vastus intermedius muscle. Management and outcomes: Surgical treatment was considered for the right thigh mass, being symptomatic 1 month after the onset and refractory to conservative treatment and rehabilitation program. At 2 months postsurgery, the patient was asymptomatic and had completed a rehabilitation program. Conclusion: Early surgical treatment followed-up with a rehabilitation program results with a complete recovery of muscle strength and range of motion. At 3 months postinitial injury, the patient was considered fully recovered and had returned to the match without reporting pain or other symptoms.

Patrick S. Ledwidge, Lindsey C. Hartland, Kirstiana Brickman, Scott O. Burkhart, and John P. Abt
Although concussion management and return to play/learn decision making focuses on reducing symptoms, there is growing interest in objective physiological approaches to treatment. Clinical and technological advancements have aided concussion management; however, the scientific study of the neurophysiology of concussion has not translated into its standard of care. This expert commentary is motivated by novel clinical applications of electroencephalographic-based neurofeedback approaches (eg, quantitative electroencephalography [QEEG]) for treating traumatic brain injury and emerging research interest in its translation for treating concussion. QEEG’s low-cost relative to other brain recording/imaging techniques and precedent in clinical and medical care makes it a potential tool for concussion rehabilitation. Although uncommon, licensed and certified clinicians and medical professionals are implementing QEEG neurofeedback for concussion management within their score of practice. These approaches are not widely adopted nor recommended by professional medical societies, likely because of a limited evidence base of well-designed studies with available standard protocols. Thus, the potential efficacy of QEEG neurofeedback for treating persistent symptoms or cognitive dysfunction after sports-related concussion is unknown. This commentary will update the concussion clinician–scientist on the emerging research, techniques, and disagreements pertaining to the translation of QEEG neurofeedback for concussion management, particularly in the treatment of persistent cognitive difficulties. This commentary will also introduce to readers the fundamentals of how the electroencephalogram may be acquired, measured, and implemented during QEEG neurofeedback. An evidence base of supportive findings from well-designed studies, including those that are retrospective, outcomes-based, and, ultimately, placebo/sham-controlled is recommended prior to considering more widespread adoption of QEEG neurofeedback approaches for treating persistent symptoms or cognitive deficits after sports-related concussion. We review the considerable barriers to this research and clinical implementation, and conclude with opportunities for future research, which will be necessary for establishing the quality and efficacy of QEEG neurofeedback for concussion care.

Development of a Real-Time Single-Leg Hop Movement Quality Assessment to Identify Lower-Extremity Biomechanical Risk Factors
Annabelle Herron, Jae Yom, Dustin R. Grooms, and Janet E. Simon
Context: The single-leg hop is based solely on performance with no measure of movement quality. The purpose of this study was to (1) develop a real-time screening tool to capture single-leg functional performance and movement quality and (2) to provide preliminary validation (criterion validity) of a trained clinician’s real-time movement quality assessment with 3D kinematics. Study Design: Cross-sectional. Methods: Fifty-nine adolescent athletes volunteered (15.2 [1.1] y, 165.8 [9.2] cm, and 61.5 [13.9] kg, 51 females and 8 males). Each participant performed 3 trials of the single-leg hop on their dominant leg. A 3-dimensional inertial measurement system was used to capture knee joint kinematics. A movement quality checklist for use during a single-leg hop (movement quality single-leg hop) was developed to score biomechanical errors based on lower-extremity injury risk factors. Four criteria were developed for the checklist: (1) knee valgus, (2) foot rotation, (3) lateral trunk flexion, and (4) erect posture. An independent t test was conducted for each dependent variable (knee flexion displacement and knee abduction displacement) by each independent variable (movement category presence of (1) lateral trunk flexion, (2) knee valgus, (3) foot rotation, and (4) erect posture/sound during landing [yes or no]). The alpha level was set at α < .05 for all analyses. Results: Knee flexion displacement was significantly decreased (P < .001, mean difference 9.40 [1.88]) and knee abduction displacement was significantly increased (P < .001, mean difference 9.41 [0.47]) for those who had knee valgus documented by the clinician. In additional, for those with visually documented erect posture/sound of landing, there was a significant decrease in knee flexion displacement (P < .001, mean difference 10.13 [2.34]). Conclusion: The movement quality single-leg hop checklist has shown promising preliminary validation (criterion validity) for clinicians to assess movement quality. Increased knee abduction and decreased knee flexion are common risk factors associated with knee injuries and this clinician friendly real-time checklist may highlight individuals who are at risk of sustaining a knee injury.
Patient Perceptions of Psychological and Rehabilitation Experiences After Anterior Cruciate Ligament Reconstruction: A Qualitative Study
Megan Murray, Meredith Wekesser, J.D. DeFreese, Christopher Kuenze, Caitlin Brinkman, Daniel Gould, and Shelby Baez
Context: Over 80% of patients anticipate fully returning to sport (RTS) within 1 year after anterior cruciate ligament reconstruction (ACLR), but only one quarter of patients succeed. Although several factors influence the RTS process, this study focused on how psychological responses to injury, such as injury-related fear and self-determined motivation, help to explain variation in rehabilitation experiences. There is limited information about how these meaningful psychological responses to injury are connected to responses such as athlete burnout or how patient perceptions of these responses relate to rehabilitation. The purpose of this qualitative study was to explore how patient perceptions of injury-related fear, self-determined motivation, and athlete burnout influence individual psychological and rehabilitation experiences at 4 to 6 months post-ACLR. Design: Qualitative study. Methods: Eight patients (female = 4, age = 16.3 ± 1.9) between 4 and 6 months post-ACLR who injured their knee playing or training for sports were included in the study. Patients completed the Sport Motivation Scale-6, Athlete Burnout Questionnaire, Perceived Stress Scale 4, and Tampa Scale of Kinesiophobia-11 to measure self-determined motivation, athlete burnout, stress, and injury fear. These questionnaires collected descriptive data used to guide audio- and video-recorded semistructured interviews. The interviews were transcribed and analyzed in a 6-stage process of thematic analysis. Results: Thematic analysis revealed 3 themes related to how participants perceived their rehabilitation experiences: (1) acknowledging recurring struggles during recovery, (2) finding motivation to RTS and normal life, and (3) successfully navigating the recovery process. In particular, participants described the impact of positive shifts in their psychological perceptions at 4 to 6 months post-ACLR. Conclusions: Patients 4 to 6 months post-ACLR described how struggles during their recovery and rehabilitation experiences were improved by positive shifts in their psychological perceptions. Increasing positive psychological awareness within a supportive rehabilitation environment may improve rehabilitation experiences and RTS rates after ACLR.

Context: Chronic ankle instability (CAI) is associated with motor-behavioral and sensory-perceptual impairments, including reduced balance performance, hip strength, and ankle function, and increased disablement, and injury-related fear. Progressive balance training (BAL) and hip strengthening (HIP) can both improve balance and function, but their comparative effects are unknown. Our objective was to compare the effects of progressive BAL and HIP on balance, hip strength, and patient-reported outcomes in those with CAI. Methods: Forty-five individuals with CAI volunteered for this randomized control study. Participants were randomly allocated to BAL, HIP, and control (CON) groups (n = 15 per group). BAL and HIP each participated in 8-week interventions while CON did not. Participants’ involved limbs underwent testing of patient-reported outcomes (Foot and Ankle Ability Measure [FAAM-ADL, FAAM-S], modified Disablement in the Physically Active Scale [mDPA], Tampa Scale of Kinesiophobia-11 [TSK-11], Fear-Avoidance Beliefs Questionnaire [FABQ], and Self-Efficacy of Balance Scale [SEBS]), Star Excursion Balance Test (SEBT), and isometric hip strength (extension [EXT], abduction [ABD], and external rotation [ER]) before and after the intervention. Multiple imputation was used for missing data. Multivariate repeated-measures analyses of variance analyzed effects of the interventions. Results: A significant group × time interaction existed for psychosocial outcomes (P = .008), but not for balance (P = .159), strength (P = .492), or ankle function and disability (P = .128). Time main effects existed for balance (P = .003), strength (P < .001), function and disability (P < .001), and psychosocial outcomes (P = .006). BAL significantly improved in SEBT, EXT, ABD, and all patient-reported outcomes. HIP significantly improved in EXT, ABD, ER, FAAM-S, mDPA, FABQ, and SEBS. Conclusions: Balance training and hip strengthening can both improve motor-behavioral and sensory-perceptual impairments in individuals with CAI; however, balance training remains the most effective option for clinicians.

Humeyra Kiloatar, Aylin Aydogdu Delibay, Nisa Turutgen, and Mihri Baris Karavelioglu
Context: The aim of this study was to investigate the acute effects of Swedish massage and manual lymph drainage (MLD) on performance parameters related to jumping, walking, and blood lactic acid levels after Nordic hamstring exercises. Design: This study was designed as a controlled crossover study. Methods: The study included 16 young trained men. Participants’ lactic acid levels, gait-related parameters, and jumping performance were assessed. Assessments were performed at baseline, after Nordic hamstring exercises, and after 3 different passive recovery strategies: resting, Swedish massage, and MLD for 3 weeks. Results: As a result of the study, it was observed that lactic acid levels after the MLD and massage intervention were significantly lower in both MLD and massage conditions compared with the control condition (P < .05). There was no within- and between-conditions difference in jumping parameters after the MLD and massage interventions (P > .05). Walking speed in the MLD condition was statistically higher following the intervention compared with both before and after exercise (P < .05). Step time in the massage condition was statistically lower after the intervention compared with after Nordic hamstring exercise (P < .05). Conclusions: Although MLD and massage interventions have positive effects on lactic acid levels and walking and jumping parameters, they are not superior to each other. MLD can be used as a passive recovery technique after exercise.
Minimizing Redislocation Rates and Restoring Function After Patella Dislocation: A Critically Appraised Topic
Matthew Senese and Veronika Smith
Clinical Scenario: Patella dislocation is a common knee injury resulting in decreased function, increased knee pain, and a higher risk of recurrent patella dislocation. Patients with patella instability are treated surgically or conservatively with physical therapy to minimize redislocation risk and restore function. Clinical Question: In individuals with a patella dislocation, how does treatment (conservative therapy versus medial patellofemoral ligament [MPFL] surgery) affect redislocation rates and patient-perceived function? Summary of Key Findings: This critically appraised topic included 3 studies assessing outcomes in individuals with patella instability treated with MPFL surgery or conservative management. Outcomes included comparing redislocation rates and Kujala scale perceived knee function between participant groups. Surgery included MPFL reconstruction (MPFL-R) in 1 randomized controlled trial and 1 prospective controlled trial and MPFL repair in another randomized controlled trial. Conservative treatment included physical therapy and bracing. All 3 studies demonstrated significantly lower redislocation rates in individuals managed with surgery versus conservative treatment. Reported knee function was significantly higher in the MPFL-R group compared with individuals conservatively managed at 2-year follow-up but not at 1 year. No significant difference in knee function was present between individuals receiving MPFL repair or conservative management at a 2-year follow-up. Clinical Bottom Line: There is moderate-level evidence to support a significant decrease in patella redislocation rates in individuals managed with MPFL surgery compared with conservative treatment. The reviewed studies suggest a significant improvement in patient-perceived knee function at 2 years following MPFL-R but no difference at 1 year following MPFL-R or 2 years after MPFL repair. Strength of Recommendations: Grade B evidence supports lower patella redislocation rates with MPFL surgery compared with nonsurgical treatment. Furthermore, this evidence suggests a potential benefit in perceived knee function 2 years after MPFL-R compared with conservative management.
Comparison of an Adaptive Ankle Brace to Conventional Taping for Rehabilitation of Acute Ankle Injury in Young Subelite Soccer Players: A Pilot Study
Dirk Krombholz, Steffen Willwacher, Tobias Consmüller, Anna Linden, Burkay Utku, and Jessica Zendler
Context: Ankle sprains are a common injury in sports, for which use of external ankle support during rehabilitation has been suggested to improve clinical outcomes. Design: Cohort study. Methods: Thirteen soccer players experiencing acute lateral ankle sprain injury were provided a novel adaptive ankle brace or conventional ankle taping (control) as external ankle support throughout the injury rehabilitation process. All other clinical procedures were identical, and rehabilitation was supervised by the same team staff member. Time from injury to clearance to return to sport was tracked. Player experience with the ankle brace also was queried via electronic surveys. Results: The median time to return to sport was less for the Brace group (52.5 d) compared to the Control group (79.5 d), but the distributions of the 2 groups were not found to differ significantly (P = .109). Player surveys indicated they felt the brace to be comfortable or very comfortable, with better freedom of movement than other braces and the same freedom of movement as wearing no brace. All players reported wearing the brace to be the same or better experience as ankle taping. Discussion: These preliminary results indicate that the adaptive ankle brace is at least as effective as ankle taping for providing external support during the rehabilitation phase following acute lateral ankle sprain and suggest it may be a more effective ankle support solution in terms of patient compliance than conventional bracing or taping.
