Context: Sport and physical activity (PA) programs are an important developmental resource for youth with Attention Deficit Hyperactivity Disorder (ADHD) and Disruptive Behavior Disorders. The purpose of this study is to assess sport participation rates, PA participation, and after-school supervision rates among African American children with ADHD and/or Disruptive Behavior Disorders. Design: In this cross-sectional study, parents of African American children with elevated symptoms of ADHD, oppositional defiant disorder, and/or conduct disorder (N = 175, 6- to 12-y-old, 31% female) reported after-school program participation over the past year. Methods: Logistic regression analyses tested relationships between ADHD symptoms, oppositional defiant disorder symptoms, and conduct disorder symptoms, likelihood of regular participation (≥2 d/wk) in sport, PA, and sedentary after-school programs, and likelihood of being supervised and unsupervised after school. All regressions controlled for age, sex, income, and medication status. Sample participation rates were descriptively compared with participation rates of same-aged peers regionally, and nationally, reported in 3 national surveys. Results: Parents in the local sample reported higher rates of sedentary after-school program participation (54%) but lower rates of PA program participation (31%), and sport participation (12%) compared with same-aged peers. The local sample was less likely to be unsupervised after-school compared with same-aged peers with only 27% of parents reporting that their child was unsupervised ≥ 2 days per week. Children endorsing oppositional defiant disorder (odds ratio = 2.05; P < .05) and conduct disorder (odds ratio = 5.74; P < .05) were more likely to be unsupervised more frequently after-school as compared with those not meeting endorsement. Conclusions: Given demonstrated benefits of youth sport programming and observed inequities in participation, there is a need to develop support models that connect parents, coaches, and social services agencies to facilitate inclusion. Sports medicine professionals are uniquely positioned to contribute to these efforts, as they are often key opinion leaders in both the youth sport and health care contexts.

Motor Point as an Alternative to Femoral Nerve Stimulation for the Assessment of Quadriceps Muscle Inhibition in Healthy Women
Klauber D. Pompeo, Rodrigo Rabello, Anete B. Morales, Kelli D. Klein, Viviane B. Frasson, Nicola A. Maffiuletti, and Marco A. Vaz
Context: The evaluation of quadriceps muscle inhibition with the interpolated twitch technique is usually performed by stimulating the femoral nerve (FN). However, there are some problems related to the use of this stimulation site, which may be partially overcome by delivering the stimulation over the motor point (MP). This study sought to compare MP to FN stimulation at different joint angles for the evaluation of quadriceps muscle inhibition, resting peak torque, and discomfort in healthy women. Design: Cross-sectional study. Methods: Sixteen healthy women (age: 28 [4] y; body mass: 60 [5] kg; height: 162 [5] cm) participated in this study. Supramaximal paired stimuli were delivered to the FN and to the rectus femoris MP before and during maximal voluntary contractions at different knee angles (15°, 30°, 45°, 60°, and 90° of knee flexion) to assess muscle inhibition and resting peak torque. Discomfort was also recorded for each stimulation site and knee angle. Results: Muscle inhibition was similar between the 2 stimulation sites (P > .05) and was higher at 45° than at 90° (P = .03). MP stimulation evoked lower resting peak torque at 30° (P = .004), 60° (P = .006), and 90° (P = .006) and higher discomfort at 30° (P = .008) and 90° (P = .027) compared to FN stimulation. Conclusions: Despite lower resting peak torque and higher discomfort at some angles, MP stimulation provided similar muscle inhibition to FN stimulation at all knee angles and is therefore a valid method to evaluate quadriceps muscle inhibition in healthy women. MP stimulation can be used as an alternative to FN stimulation for the evaluation of quadriceps muscle inhibition with no added discomfort at the angles where muscle inhibition is the highest.
Self-Compassion and Willingness to Adhere to Return-to-Play Protocol Following Sport-Related Concussions
Kiera Wortley and Benjamin J.I. Schellenberg
Context: Athletes who do not follow proper concussion recovery protocols are likely to experience their symptoms for longer while putting themselves at risk of further health issues. It is, therefore, critical to identify the types of athletes who may be more or less likely to follow the guidance of medical professionals following concussions. In this research, we tested the hypothesis that athletes with higher levels of self-compassion would be more willing to follow concussion recovery protocols. Design: Cross-sectional study. Methods: We collected data from 2 samples of combat sport athletes (sample 1, N = 173 and sample 2, N = 172). All participants completed online surveys assessing self-compassion, the likelihood that they would follow 10 recovery recommendations if they were to experience a concussion in their sport, and scales assessing 3 covariates: self-esteem, conscientiousness, and sport competitiveness. Results: After controlling for self-esteem, conscientiousness, and sport competitiveness, the results of multiple regression analyses in both samples showed that self-compassion was positively associated with willingness to follow concussion recovery recommendations (sample 1: β = 0.19, 1-tailed P = .039; sample 2: β = 0.20, 1-tailed P = .025). The results of a mini meta-analysis of these effects supported this positive association, Mean r = .144, Z = 2.666, 1-tailed P = .004. Conclusions: Athletes who are highly self-compassionate reported a greater willingness to follow the advice of medical professionals and adhere to return-to-play protocol. This finding has implications for the rehabilitation of sport concussions; it may be advantageous to encourage athletes to be kind and compassionate toward themselves throughout the concussion recovery process.
Hip Fracture in the Sportive Adult: Case Report of Complete Functional Recovery After Removal of Hardware
Pieter Lormans, Pieter-Jan Loos, Stefanie Vanbrabant, Philippe Quetin, Xavier Huybrechts, and Olivier Ghekiere
Context: Pertrochanteric hip fractures in sportive young adults are mainly caused by a high-energy trauma and treated in the same way as in the older population, using an osteosynthesis immediately followed by a rehabilitation program for several months. The current standard is not to remove osteosynthesis material, similar to the case of older patients. Case Presentation: A 45-year-old male cyclist experienced a right pertrochanteric femoral fracture, treated with cephalomedullary nails. After 9 months of adequate rehabilitation, weakness of the quadriceps musculature and functional complaints persisted, objectified through an isokinetic strength test and a significantly reduced score on the Hip Disability and Osteoarthritis Outcome Score questionnaire. The patient was unable to return to his previous level of cycling performance. Management and Outcome: After exclusion of structural bone complications, nerve injury, and central sensitization, the functional complaints and strength deficiency were hypothesized to be related to the osteosynthesis material. Therefore, the hardware was removed 9 months after the first surgery, and the rehabilitation was continued for another 20 weeks. Very soon after the removal of the hardware, the functional complaints disappeared with a remarkable improvement of the Hip Disability and Osteoarthritis Outcome Score. The isokinetic strength test showed complete recovery of muscle strength 20 weeks after osteosynthesis removal, and preinjury cycling performance values were obtained 9 months posthardware removal. Conclusion: Despite an adequate rehabilitation following a hip fracture, sporty young adults may fail to reach their previous level of functioning. Osteosynthesis removal may be indicated in this sportive population to reach complete muscle strength and functional recovery. The management of hip fractures in the sportive young adult and the identification of patients who may benefit from removal of the hardware require more research.

Objective: To culturally adapt and validate the Italian version of the Shoulder Instability—Return to Sport after Injury (SI-RSI-I) scale. Methods: The SI-RSI-I was developed by adapting the Anterior Cruciate Ligament—Return to Sport Index—Italian version and replacing the term “knee” with “shoulder.” Subsequently, it underwent validation following COSMIN recommendations. The study involved athletic participants who experienced SI. They completed the SI-RSI-I together with other measurement instruments: Western Ontario Shoulder Instability Index, Kerlan-Jobe Orthopedic Clinic Score, EuroQol-5D-5L, and Numeric Pain Rating Scale. The following psychometric properties were investigated: structural validity, internal consistency, test–retest reliability, measurement error, and construct validity. Results: The study included 101 participants (age mean [SD] 28.5 [7.4] y; 83 males, 18 females). The SI-RSI-I showed a single-factor structure, excellent internal consistency (α = .935), and excellent test–retest reliability (ICC = .926; 95% CI, .853–.964). The standard error of measurement was 6.1 points, and the minimal detectable change was 17.0 points. Furthermore, SI-RSI-I demonstrated moderate to strong correlations with all reference scales, confirming 8 out of 9 (88.0%) hypotheses, thus establishing satisfactory construct validity. Conclusion: The SI-RSI-I has demonstrated robust internal consistency, reliability, validity, and feasibility as a valuable scale for assessing psychological readiness to return to sport in Italian athletes with SI.

Zaid Al Ta’ani, Omar Al Ta’ani, Ahmad Gabr, Mohammad Tanashat, Justin Lin Lee, Farah Al-Bitar, Jessica Lin Lee, and Yazan A. Al-Ajlouni
Context: Anterior cruciate ligament (ACL) injuries, prevalent in athletic contexts have profound physical and psychological impacts. Despite extensive research on the physiological aspects of ACL recovery, the psychological dimensions of this process have gained increased attention. This scoping review delves into the intricate landscape of psychological factors influencing ACL rehabilitation. Design: Scoping review. Methods: A literature search across multiple databases was conducted to identify relevant published studies that provide insight into the psychological aspects of ACL recovery. This search spanned various study designs, enabling a nuanced understanding of the psychological intricacies surrounding ACL recovery. Overall, a total of 1830 unique articles were screened, of which 66 were included in this review. Our findings are further contextualized through alignment with insights from prior reviews on similar themes. Through a comprehensive analysis of diverse literature, we explore 3 key themes: psychological challenges, current rehabilitation programs, and the integration of psychological support. Results: Psychological challenges emerged as a pervasive aspect of ACL rehabilitation, encompassing fear, anxiety, motivation, and depression. The nuanced emotional responses, particularly the fear of reinjury, impact treatment adherence and overall well-being. Contemporary rehabilitation programs revealed inconsistencies in incorporating psychological support, emphasizing the need for standardized, multidisciplinary approaches. The alignment with prior reviews in the literature reinforced the importance of psychological traits, such as knee self-efficacy, in predicting positive outcomes. Conclusion: This scoping review provides a comprehensive overview of psychological factors within ACL rehabilitation, highlighting the importance of tailored interventions and standardized approaches. The integration of multidisciplinary expertise emerges as crucial for optimizing patient outcomes. Our findings not only contribute to a nuanced understanding of psychological nuances in ACL rehabilitation but also offer valuable implications for clinical practice and policy development.
Effects of Foam Rolling Prior to Proprioceptive Neuromuscular Facilitation Stretching on Hamstring Flexibility and Thigh Skin Temperature
Sinem Yenil, Gamze Yalcinkaya Colak, and Seher Ozyurek
Context: Proprioceptive neuromuscular facilitation stretching (PNFS) is suggested to improve the range of motion and flexibility as an active warm-up. Recently, the foam rolling (FR) methods have also emerged as a passive warm-up. However, the combined effects of PNFS and FR are still unclear, and no reports have compared their effects using thermal imaging. This study investigated the acute effects of combining nonvibration FR (NVFR) and vibration FR (VFR) prior to PNFS, in comparison with PNFS alone, on hamstring flexibility and thigh skin temperature. Design: Randomized controlled trial. Methods: Participants (n = 60) were randomly assigned to PNFS, NVFR + PNFS, VFR + PNFS, and control group (CG). Active knee-extension (AKE), sit and reach (SR) test, and thermal imaging were evaluated before (pre-int), immediately after (post-int), and 30-minutes after (post30-int) intervention. Results: All intervention groups had a significant increase at all time periods (P < .001) except the CG in terms of AKE and sit and reach test (P > .05). Combined (NVFR + PNFS/VFR + PNFS) groups had also a significant increase in the post30-int compared with pre-int and post-int values of thigh skin temperature (P < .001). Combined groups, over time, had the best post30-int effect on increasing skin temperature. The study found a significant interaction effect between interventions and time across several measurements (P < .05). Combined groups showed more significant improvements in AKE compared to CG at post-int (P < .05). There is a similar change in AKE, SR test, and skin temperatures between combined groups and PNFS alone at both post-int and post30-int (P < .05). Conclusions: These findings indicate that using FR, with or without vibration, before PNFS does not provide an additional benefit in improving hamstring flexibility and thigh skin temperatures compared with PNFS alone.
Athlete Sleep Screening Questionnaire in Japanese: Adaptation and Validation Study
Yuka Tsukahara, Satoshi Kodama, Saaya Kikuchi, and Carly Day
Context: General screening methods for athletes are limited. This study aims to analyze the reliability and validity of the Japanese version of the athlete sleep screening questionnaire. Methods: In total, 111 female collegiate athletes completed the initial test and retest. The independent variables included the kind of sports of the participants and their athletic level, grade (freshman, sophomore, junior, and senior), and age. The reliability of the questionnaire was assessed using Cronbach’s alpha and intraclass correlation coefficients. Athletes competing in team sports and individual sports were compared to evaluate for differences. Results: A total of 38.7% of athletes had moderate to severe sleep difficulty score. Their Cronbach’s alpha for test and retest were .34 and .44, respectively. The intraclass correlation coefficient indicated sufficient internal consistency and test–retest validity. The mean sleep difficulty scores were 7.0 (2.3) and 6.5 (2.1) for test and retest, but no significant difference was observed between the individual and team sport athletes. Results of multivariable regression analysis revealed that having sleep and performance issues during travel was related to sleep difficulty scores (Coef 1.44, P < .01). Conclusions: Athletes of all levels have sleep disorders. The Japanese version of athlete sleep screening questionnaire has been validated with sufficient test–retest validity but has poor internal consistency. Thus, although Japanese version of the athlete sleep screening questionnaire is an appropriate questionnaire for assessing sleep disorders in athletes whose primary language is Japanese, future research is needed to optimize the questionnaire accounting for cultural variation.
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.
Is It Possible to Improve Performance in Competition After an Adductor Longus Injury in Professional Football Players?
José Luis Estévez-Rodríguez, Jesús Rivilla-García, and Sergio Jiménez-Rubio
Context: Adductor longus muscle strains are one of the most common injuries occurring in intermittent sports such as soccer. Objective: The purpose of this study was to know the effect of a specific rehabilitation and reconditioning program, which was previously validated, after adductor longus injury in professional soccer players. Methods: A specific rehabilitation and reconditioning program was applied to 11 injured male professional soccer players. Participants: Eleven male professional soccer players (age = 29.18 [4.45] y; height = 179.64 [4.97] cm; mass = 75.33 [3.84] kg). Interventions: In the first place, the days taken to return to full team training and to return to competition (RTP) was analyzed; second, the most important performance parameters were analyzed and compared in the preinjury match (PRE) and after the return to competition at 2 different points in time (RTP1–RTP2). Results: The return to full team training recorded was 11.91 (1.92) days and the RTP was 15.36 (3.04) days. Match performance parameters showed significant improvements after injury. Significant improvements were observed during RTP2, in the variables of high-speed running (P = .002), very high-speed running (P = .006), acceleration (>3 m/s2; P = .048), and high metabolic load distance (P = .009). Conclusion: The results allow us to conclude that this program was very effective, as it allowed the players to obtain similar and/or higher performance values in a reduced period of time after the injury.
