Context: Social determinants of health including insurance type, income, race, and ethnicity have been shown to influence the utilization of physical therapy and recovery after an orthopedic injury. The influence of social determinants of health on the utilization of physical therapy and recovery from concussion is not well understood.

Design: Prospective observational registry study in a specialty concussion program.

Methods: Patients diagnosed with a concussion using the Postconcussion Symptom Inventory and the visio-vestibular examination (VVE) who were also referred to physical therapy were included. The main outcomes of interest were the number of days from referral to initial physical therapy evaluation and the number of physical therapy visits completed. Information related to patients' age, race, ethnicity, sex, insurance type, and Child Opportunity Index was extracted from the registry. Multivariate and univariate regressions were used to assess the associations of each sociodemographic characteristic with the outcomes.

Results: A total of 341 patients diagnosed with concussion between January 2017 and December 2023 met inclusion criteria. The average age was 14.77, and 64% were female. Patients' age, race, ethnicity, insurance type, and Child Opportunity Index were not associated with days to evaluation or length of care in physical therapy. Higher PCSI scores in children under 12 years (coefficient: 0.17, 95% CI, 0.06-0.29) and female sex (coefficient: 1.2, 95% CI, 0.26-2.1) were associated with a longer course of care in physical therapy. Patients with an abnormal VVE score had on average 2.1 more physical therapy visits than those with a normal VVE score (coefficient: 2.1, 95% CI, 0.73-3.5).

Conclusions: Higher PCSI scores in children, female sex, and higher VVE scores in general predicted a longer course of care in physical therapy. Implementation of a clinical care pathway for concussion care using the PCSI and the VVE may be one strategy to help mitigate systemic factors that might otherwise negatively influence access to physical therapy.

Context: Evidence indicates a 2 to 3 times increased risk of musculoskeletal injury after return to play from concussion. Undetected neuromuscular control deficits at return to play may relate to increased musculoskeletal injury risk. Rehabilitation to improve neuromuscular control may benefit patients with concussion, but access to rehabilitation professionals and/or poor adherence may limit efficacy. Our purpose was to determine the feasibility of an 8-week virtual neuromuscular training (NMT) program administered through a novel smartphone application among physically active, uninjured adults.

Design: Feasibility trial.

Methods: Participants were instructed to complete an NMT program administered via a smartphone application and returned for follow-up questionnaires 8 weeks later. They were instructed to complete 3 asynchronous self-guided workouts per week during the 8-week intervention period. Workouts included balance, plyometrics, strengthening, and dual-task exercises. The application provided instructions for each exercise using video, text, and audio descriptions. Our primary feasibility measure was participant adherence, calculated as the percentage of workouts completed out of the total possible 24 workouts. We recorded the average duration of each workout using start/stop/advance features within the application.

Results: Twenty participants were enrolled, of which 15 (age = 26.3 [2.7] y, 67% female) returned for follow-up (75% retention). Participant adherence was 57.2% (25.0%; range: 16.7%-91.7%). Participants spent 17.3 (8.0) minutes per workout (range: 7.4-37.9 min). There were no adverse reactions or injuries. Most participants (60%) reported time availability as a primary barrier to intervention completion.

Conclusions: Participants were moderately (>50%) adherent to a virtual NMT program, without any reported injuries. We identified several barriers to participation and pathways for improved adherence in the future. The virtual NMT program completed by uninjured adults provides evidence of its feasibility and future scalability to those with a recent concussion to address neuromuscular control deficits and reduce future injury risk.

Context: The sequelae of concussion may have psychological consequences that affect an athlete's ability to return to play (RTP). However, confidence of RTP readiness is rarely monitored after a concussion.

Design: This study examined the acute and longitudinal implications of concussion on an athlete's confidence to RTP, the relationship between self-reported symptoms and athlete confidence to RTP, and interactions between concussion symptoms, sex, sport type (contact vs noncontact), and confidence to RTP.

Methods: Forty-six college athletes (65% female) sustained a concussion and completed the Injury Psychological Readiness to Return to Sport (I-PRRS) scale at 3 timepoints: within 72 hours of injury (acute), within 72 hours of beginning the RTP protocol (pre-RTP), and within 72 hours of being fully cleared to RTP (post-RTP).

Results: Athletes reported acute low confidence after concussion (I-PRRS mean [SD] = 32.59 [18.45]), which improved over time (pre-RTP mean [SD] = 52.11 [9.60]; post-RTP mean [SD] = 57.45 [5.96]). Some athletes returned to competition (post-RTP) with lingering confidence concerns (ie, I-PRRS < 50; 95% CI = 0.03-0.26). Acute symptom severity was associated with worse confidence (P < .001). Sex and sport type (contact vs noncontact) had no relationship with confidence (P = .406, P = .3314, respectively). These results indicate that athletes lack confidence acutely (within 72 h) following concussion.

Conclusions: Although confidence improves over time, those who report greater acute symptoms also exhibit decreased confidence, and some athletes are returning to play with lingering concerns about their confidence (I-PRRS < 50). This preliminary evidence of heterogeneous confidence following concussion encourages the assessment and monitoring of confidence throughout concussion rehabilitation.

Context: Translating new evidence into clinical practice is a dynamic and iterative process. Research is ever evolving specific to concussion rehabilitation and requires a systematic approach rooted in science for translation into clinical practice. The knowledge-to-action (KTA) cycle framework is an effective strategy to ensure optimal outcomes and sustainability. The objective of this study was to investigate changes in clinical outcomes and clinician self-efficacy specific to concussion management in a suburban health care system utilizing the KTA framework.

Design: Pretraining and posttraining intervention study.

Methods: Rehabilitation professionals were electronically surveyed pre-post targeted concussion educational intervention. Questions were adapted from the General Self-Efficacy scale and tailored specifically to confidence in current concussion management. Retrospective chart reviews were also completed pre-post knowledge translation educational intervention to examine practice patterns. Data from the presurvey and retrospective chart review were utilized to identify the know-do gap and design intentional educational interventions. Statistical analysis was performed utilizing SPSS (version 28).

Results: Within-group differences revealed an increase in confidence with evaluation (P = .01), intervention (P = .01), and consultation (P = .01) in concussion management. When comparing physical therapists who participated in the intervention with those who did not, there was significantly higher self-confidence in all areas (P ≤ .001) for those who engaged in the educational intervention. Pre-post chart reviews revealed improvement in clinical practice patterns in the following constructs: use of patient-reported outcome measures (P ≤ .001), objective outcome measures (P = .002), exertional testing (P ≤ .001), completion of comprehensive evaluation (P ≤ .001), and use of evidence-based practice (P ≤ .001).

Conclusions: Utilizing the KTA framework resulted in improved self-efficacy of clinicians as well as improved clinical practice patterns in concussion management in an outpatient hospital-based practice. The KTA framework is a potential tool for translating current evidence related to concussion management for improved clinical outcomes.

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.

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.

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.

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.
