Diving Into Sports Specialization: The Association of Early Specialization on Injury Rates in Youth to Young Adult Divers.

OBJECTIVES: This study explored the link between early sports specialization and injury rates in youth divers, a relationship that remains largely unexplored within diving. DESIGN: Cross-sectional survey. SETTING: Members of the USA Diving Organization and collegiate male and female divers participated in an online survey, reporting their sports involvement and injury history. PARTICIPANTS: One hundred eighty-two male and female divers aged 8 to 25 years were recruited through USA Diving or US collegiate team databases. INDEPENDENT VARIABLES: Early/late specialization (based on age <12 or 12 years or older), gender (M/F), springboard and/or platform divers, experience (junior/senior, regional/zone/national/international), hours of dryland/water training, and prior sport exposure. MAIN OUTCOME MEASURES: Injury history obtained on questionnaire. RESULTS: One hundred eighty-two divers were surveyed; 70% female. Age to start diving and age to concentrate solely on diving were significantly associated with certain injuries (P < 0.05). Beginning diving before age 13 years of age was significantly associated with lower odds of injuries in the shoulder and wrist (P = 0.013 and 0.018, respectively), after adjusting for select covariates. Age of specialization was not significantly associated with injuries in any body part (P > 0.05), after adjusting for covariates. Greater years of diving experience was significantly associated with diving injuries in all 11 body parts (P < 0.05). CONCLUSIONS: This study indicates that early sports specialization is associated with decreased injury rates in elite youth divers who specialized before age 13 years, particularly for head/neck, shoulder, and wrist injuries. Moreover, we observed a positive correlation between experience and injury rate. Further investigation should focus on distinguishing between acute and overuse injuries.

SalterHarris fractures in paediatric skiers and snowboarders.

The incidence of paediatric fractures among winter sport athletes is not adequately studied. Our objective was to categorize fractures that occurred in paediatric skiers and snowboarders at a single ski resort. X-rays of 756 skiers/snowboarders aged 3-17 diagnosed with a fracture were categorized using the Salter-Harris (SH) classification. SH fractures were seen in 158 (21%) patients, with 123 (77%) being Type II. There were no significant differences between patients with a SH fracture and patients with a non-SH fracture for age, sex, snowboarding or skiing, mechanism of injury, terrain or the resort conditions on the day of injury. The most common mechanism of injury was falling onto snow while collisions resulted in more severe injuries. Compared to fractures without growth plate involvement, a higher proportion of SH fractures were seen in the humerus, radius, fibula and thumb; a lower proportion of SH fractures were observed at the tibia and clavicle.

Athlete Burnout Is Associated With Perceived Likelihood of Future Injury Among Healthy Adolescent Athletes.

We examined perceived risk of future sports injury and athlete burnout among uninjured adolescent athletes. Uninjured high school athlete participants completed the Athlete Burnout Questionnaire (ABQ) and a questionnaire assessing attitudes toward likelihood of sustaining a future sport-related injury. We compared ABQ responses between injury risk perception groups: those who expected injury versus those who did not. Half of the participants reported a somewhat/very high likelihood of future sport-related injury (n = 98; 52% female; age = 15.3 ± 1.9 years), while the other half reported it was unlikely/not possible (n = 98; 45% female; age = 15.3 ± 1.3 years). A significantly greater proportion of those in the expected injury group reported a history of bone/muscle/ligament/tendon injury (56% vs 24%; P < .001). Those in the expected injury group reported higher athlete burnout scores (median = 28 [interquartile range = 25-34] vs 25 [23-30]; P = .002). Adolescent athletes who reported they were likely to experience a future injury in their sport also reported greater levels of burnout.

Changes in Quality of Life, Sleep, and Physical Activity During COVID-19: A Longitudinal Study of Adolescent Athletes.

CONTEXT: The abrupt cessation of school and sport participation during the COVID-19 pandemic may have negative implications for adolescent mental health. OBJECTIVES: To (1) compare mental, physical, and social health and behaviors during pandemic-related stay-at-home mandates with the same measures collected 1 to 2 years earlier and (2) evaluate the relationships between physical activity and sleep during the pandemic and changes in anxiety, fatigue, and peer relationships between assessment times. DESIGN: Cohort study. SETTING: Pediatric sports medicine center. PATIENTS OR OTHER PARTICIPANTS: A total of 39 high school athletes (25 adolescent girls, 14 adolescent boys; age = 16.2 ± 0.9 years). MAIN OUTCOME MEASURE(S): Patient-Reported Outcome Measurement System anxiety, fatigue, and peer relationships short forms and the Pittsburgh Sleep Quality Index were completed twice (initial assessment in May 2018 or 2019, follow-up assessment in May or June 2020). Frequency and duration of physical activity and frequency of interaction with other individuals (family, peers, sport coaches, etc) were self-reported at follow-up assessment for the 2 weeks before school or sport closure and the 2 weeks before questionnaire completion. RESULTS: Higher levels of anxiety (5.5 ± 4.0 versus 3.6 ± 3.4 points; P = .003) and fatigue (5.4 ± 3.7 versus 2.3 ± 2.5 points; P < .001) and worse sleep quality (6.6 ± 2.9 versus 4.3 ± 2.3 points; P < .001) were observed during the pandemic compared with previous assessments. Reductions in physical activity were noted between assessments (exercise duration: 86.4 ± 41.0 versus 53.8 ± 30.0 minutes; P < .001). Sleep quality but not physical activity during the pandemic predicted changes in fatigue (P = .03, ß = 0.44 [95% CI = 0.06, 0.83]) and peer relationships (P = .01, ß = -0.65 [95% CI = -1.16, -0.15]) from initial to follow-up assessment. CONCLUSIONS: Mental and physical health declined during stay-at-home mandates compared with assessments 1 to 2 years earlier. Physical activity behaviors and sources of social interaction underwent changes after school and sport cessation. Sleep quality may have provided some protection against declining adolescent mental health during the pandemic, although this relationship requires further investigation.

Are Different Aged Youth Skiers and Snowboarders Experiencing Different Injury Characteristics?

INTRODUCTION: Skiing and snowboarding are popular winter sports with significant youth participation and inherent potential for injury. We investigated the relationship between age and injury characteristics exhibited by youth skiers and snowboarders. METHODS: In this cross-sectional study, we investigated injury characteristics among youth skiers and snowboarders at a ski resort, examining the association between age and injury type. We compared injury characteristics among young children (aged 3-6 y), school-aged children (aged 7-14 y), and older adolescents (aged 15-17 y) using χ2, and examined predictive variables for injuries at different anatomical locations using logistic regression. RESULTS: Compared with snowboarding, skiing was associated with greater odds of lower extremity (adjusted odds ratio [aOR]=6.8, 95% confidence interval [CI]: 4.89, 9.47, P<0.001) and head/face/neck (aOR=1.63, 95% CI: 1.20, 2.21, P=0.002) injuries. Compared with skiing, snowboarding was associated with greater odds of upper extremity injury (aOR=5.9, 95% CI: 4.6, 7.6, P<0.001). Age group significantly affected injury mechanism (χ2 [df=12, n=1129]=42.882, P<0.0001) and diagnosis (χ2 [df=12, n=1129]=43.093, P<0.0001). Young child skiers had the highest proportion of injuries to the head/neck/face and lower extremities and a significantly higher proportion of collision injuries and fractures than older skiers. Young child skiers most frequently injured the lower leg/ankle, while older skiers most frequently injured the knee. CONCLUSIONS: Youth skiers exhibited predominately lower extremity injuries, while snowboarders exhibited predominately upper extremity injuries. Age significantly affected injury mechanism and injury diagnosis in youth skiers. Specifically, younger skiers tended to suffer more fractures and collision injuries than older youth skiers.

Early Sport Specialization and Past Injury in Competitive Youth Rock Climbers.

INTRODUCTION: Sport specialization has been shown to have negative effects on athletes but has not been studied within rock climbing. This study seeks to evaluate the proportion and impact of specialization in pediatric climbers. METHODS: Climbers (ages 8-18 y) were recruited from throughout the United States to complete a 1-time survey regarding climbing experience, training patterns, and injury history. The main outcome of proportion of climbers suffering an injury was assessed within the last 12 mo and within their entire climbing experience (defined as "lifetime" injury). Early specialization was defined as exclusive participation in climbing, with training for >8 mo‧y-1, prior to age 12 y (late specialization if after age 12 y). RESULTS: Participants (n=111, 14±3 y [mean±SD], 69 females) were high-level climbers. Fifty-five percent of participants specialized in climbing, and 69% of those specialized early. Hand and ankle injuries occurred most commonly. Seventy-eight percent of late specialized climbers had a lifetime injury. Late specialized climbers were 1.6 times (95% CI: 1.1-2.3) more likely than early specialized climbers to have had a lifetime injury and 1.8 times (95% CI: 1.1-2.8) more likely to have had an injury in the last 12 mo. No difference in overuse injuries was found between specialization groups. CONCLUSIONS: Early specialization is common among youth climbers but was not associated with an increase in injuries. Late specialization was associated with a higher likelihood of having had a climbing injury in the last 12 mo and during an entire climbing career.

Age is associated with postural control performance following youth concussion.

PURPOSE: To examine the effect of age on postural control outcomes among patients being seen during their initial post-concussion clinical visit. METHODS: Youth patients were seen≤14 days post-concussion, and completed a series of postural control evaluations: tandem gait, Romberg, and Balance Error Scoring System (BESS) tests. RESULTS: We included 109 children 8-12 years of age (24% female, evaluated median = 7 [interquartile range = 4-10] days post-injury) and 353 adolescents aged 13-18 years (36% female, evaluated median = 7 [4-10] days post-injury). There was a higher proportion of children who demonstrated abnormal tandem gait relative to adolescents (26% vs. 11%; p < 0.001). They also made more BESS errors in single (median = 5 [2-10] vs. 4 [2-6] errors) and tandem (median = 3 [1-6] vs. 2 [0-4]) firm stances. After covariate adjustment, children demonstrated worse tandem gait (adjusted odds ratio = 3.05, 95% CI = 1.68-5.53) and more firm surface BESS errors (double stance ß=0.51, 95% CI = 0.22-0.80; single stance ß= 1.18, 95% CI = 0.42-1.95; tandem stance ß= 0.98, 95% CI = 0.28-1.68) than adolescents. CONCLUSIONS: Tandem gait and BESS performance following concussion differ in children compared to adolescents who present within 2 weeks of injury. Clinicians assessing and managing concussion should recognize age differences in postural control performance when assessing those with concussion.

Is near point of convergence associated with symptom profiles or recovery in adolescents after concussion?

Our purpose was to compare the clinical and injury characteristics of concussion patients with a receded near point of convergence (NPC) vs those without a receded NPC. Concussion patients were seen within 14 days of injury. We compared those with receded a NPC (>6 cm) break point distance and those with a normal NPC distance on symptom, behavioral, and clinical assessments. We also compared NPC break points between those who did/did not recover within 28 days of injury. 123 patients completed the assessment. 77/123 (63%) of participants demonstrated a receded NPC when tested within 14 days of injury. Those with receded a NPC break point (n = 77; mean = 14.9, SD = 1.5 years; 47% female) were significantly younger than those with a normal NPC break point (n = 46; mean = 15.7, SD = 1.7 years; 46% female). The receded NPC break point group had a significantly greater proportion of patients reporting headaches (86% vs. 61%), as well as significantly greater cognitive (mean = 13.4, SD = 8.7 vs. mean = 8.8, SD = 8.6), somatic (mean = 10.0, SD = 5.9 vs. mean = 6.9, SD = 6.6), and overall (mean = 23.7, SD = 13.6 vs. mean = 15.8, SD = 14.4) symptom severity. Our multivariable model indicated among all potential predictor variables, more severe somatic symptoms were significantly associated with a greater NPC break point (ß = 0.26; 95% CI = 0.01, 0.52). The group who went onto experience persistent symptoms had a significantly greater NPC break point at initial evaluation than those without persistent symptoms (mean = 9.7, SD = 7.5 cm vs. mean = 7.0, SD = 4.0 cm). Those with a receded NPC break point at initial evaluation showed an increased symptom burden, most notable with somatic symptoms, compared with those without a receded NPC break point.

Family Affluence Relationship to Sports Specialization in Youth Athletes.

Our objective was to examine the association between participant-reported family affluence and sport specialization level. We conducted a cross-sectional investigation of adolescent athletes. Specifically, participants completed a level of sport specialization (low/moderate/high) questionnaire and the Family Affluence Scale. The majority (52%) of the 195 youth athlete participants reported low, 33% reported moderate, and 15% reported high sport specialization. Sport specialization groups were similar in age (mean = 15.3 ± 1.6 years), proportion of females (49%), and time spent training (mean = 11.9 ± 5.0 hours per week). The high sport specialization group reported significantly greater family affluence than the low sport specialization group (Family Affluence Scale = 10.4 ± 1.7 vs 9.2 ± 1.9; P = .005). After covariate adjustment, higher levels of sport specialization remained significantly associated with greater family affluence (ß = 0.48, 95% confidence interval = 0.11-0.86). Understanding the relationship between family affluence and sports specialization affords an opportunity to better identify and monitor populations likely to specialize in a single sport during high school.

Web-Based Exercise Program Increases Cervical Strength in Adolescent Athletes.

ABSTRACT: Wilson, JC, Levek, C, Daoud, AK, Brewer, M, Brooks, K, Sochanska, A, Randall, M, and Provance, AJ. Web-based exercise program increases cervical strength in adolescent athletes. J Strength Cond Res 35(4): 1149-1155, 2021-This cohort study aimed to evaluate the efficacy of a web-based 6-week cervical strengthening program on cervical strength in adolescent athletes. It was hypothesized that subjects completing the program would demonstrate significant increase in cervical muscle strength compared with baseline strength. Eighty-three high school soccer athlete subjects were recruited from 2 local nationally competitive soccer clubs. Teams were assigned to either control or intervention groups to minimize information crossover. Fifty subjects were recruited to the intervention group (29 male, 21 female; average age 15.1 years). Thirty-three subjects were recruited to the control group (21 male, 12 female; average age 15.1 years). Intervention group subjects completed a web-based progressive cervical strengthening program over 6 weeks. Cervical strength in flexion, extension, right and left lateral flexion (LLF) was measured in Newton (N) of force at 3 time points during the competitive season for both control and intervention groups. Intervention group subjects significantly increased cervical strength [mean difference (95% confidence interval)] in LLF [24.1 (15.9-32.4)], extension [27.9 (18.4-37.5)], right lateral flexion [18.8 (11.6-26.1)], and flexion [mean ratio: 1.2 (1.1-1.2)] at follow-up testing; whereas control subjects did not see significant changes in strength. A web-based progressive cervical strengthening program improves cervical muscular strength in a population of adolescent athletes over a period of 6 weeks. Such a program could be used by researchers in future studies evaluating the influence on concussion risk and by practitioners as a means of reducing sport-related head and neck injuries.

Isometric Cervical Muscular Strength in Pediatric Athletes With Multiple Concussions.

OBJECTIVE: To compare maximal cervical muscle strength among athletes with a history of 2 or more concussions relative to athletes with no history of a previous concussion. DESIGN: Athletes in the 2 groups were frequency-matched. Linear mixed models were used to test for differences in peak isometric flexion, extension, left lateral flexion, and right lateral flexion cervical muscle torque between groups. SETTING: Pediatric sports medicine clinic. PARTICIPANTS: Athletes with a history of multiple concussions (n = 16) and athletes with no previous concussion history (n = 17). INTERVENTIONS (OR ASSESSMENT OF RISK FACTORS OR INDEPENDENT VARIABLES):: Concussion history (group), age, sex, neck girth, and height. MAIN OUTCOME MEASURES: Peak isometric torque measured with a stationary isokinetic dynamometer during a 3-second isometric hold. RESULTS: There was no significant difference in peak flexion [mean difference: 21.2%, 95% confidence interval (CI): -6.6% to 57.4%, P = 0.1413], extension (mean difference: 17%, 95% CI, -6.8% to 47.1%, P = 0.1667), left lateral (mean difference: 4.4%, 95% CI, -16.9% to 31.1%, P = 0.7011), or right lateral (mean difference: 9.3%, 95% CI, -14.5% to 39.8%, P = 0.4627) isometric torque in the concussion group relative to the control group. Across all muscle actions, neck torque was significantly (P < 0.05) higher in male compared with female athletes. Increasing neck girth was also associated with a significant (P < 0.05) increase in neck torque. CONCLUSIONS: There was no evidence of a consistent cervical muscle strength deficit among athletes with a history of 2 or more concussions relative to athletes with no previous history of a concussion. Age, neck girth, and sex were significantly associated with cervical muscle strength. CLINICAL RELEVANCE: Isometric cervical muscle strength testing may not be a reliable test for differentiating athletes with a history of multiple concussions relative to athletes with no history of concussions in the pediatric and adolescent population. Our study presents a reliable methodology for testing cervical muscle strength among young athletes.

Comparison of pediatric sports fracture outcomes based on provider type.

Objective: Pediatric primary care sports medicine physicians and pediatric sports medicine orthopedic surgeons, in conjunction with physician assistants (PAs), often manage patients with fractures. We sought to determine if pediatric patients with fractures seen by primary care sports medicine physicians had similar outcomes and satisfaction as those seen by orthopedic surgeons. Methods: We performed a retrospective chart review of four to 18-year-old patients who were treated by a sports medicine provider (primary care or orthopedic surgeon/PA) for a fracture of the radius, ulna, tibia, or fibula. Patients or their parents completed a patient satisfaction survey (Short Assessment of Patient Satisfaction [SAPS]) and an injury location-specific patient-reported functional outcome tool: the Foot and Ankle Ability Measure (FAAM) or the Disabilities of the Arm, Shoulder, and Hand (DASH) Scale. Results: Fifty-seven (70%) of the 82 patients were treated by pediatric primary care sports medicine physicians and 25 (30%) were treated by a pediatric sports medicine orthopedic surgeon or surgical PA. The median time from injury to clinically confirmed healing was similar between the two groups (47 vs 60.5 days; p = 0.54), as was the patient satisfaction (SAPS median score = 26 [range = 19-28] vs 24 [range = 9-28]; p = 0.12). Patient-reported outcomes did not differ significantly between groups for the functional outcome tools. Conclusions: Patients seen by pediatric primary care sports medicine physicians and sports medicine orthopedic surgeons have similar patient-reported fracture outcomes and similar satisfaction with care. Pediatric patients with fractures will likely have favorable outcomes when cared for by either of these subspecialty providers.

Sleep Problems and Melatonin Prescription After Concussion Among Youth Athletes.

OBJECTIVES: To examine the effect of sleep disturbances on concussion symptom recovery and to examine the effect of melatonin prescription on symptom improvement among concussed adolescents with sleep problems. DESIGN: Longitudinal test-retest. SETTING: Sports medicine clinic. PARTICIPANTS: Patients aged 8 to 18 years, diagnosed with a concussion, evaluated within 14 days after injury, and evaluated again 15 to 35 days after injury. INDEPENDENT VARIABLES: We grouped patients based on whether they reported sleep disturbances within 14 days of injury. MAIN OUTCOME MEASURES: Outcome measures included symptom severity, headache severity, melatonin prescription, and the change in symptom severity between visits. RESULTS: Two hundred twenty-five patients were included: 36% who reported sleep problems (44% female; age = 14.4 ± 2.0 years; evaluated 7.3 ± 3.8 and 23.2 ± 5.4 days after injury) and 64% who did not (32% female; age = 14.6 ± 2.3 years; evaluated 7.2 ± 3.4 and 23.0 ± 5.3 days after injury). Those with sleep problems reported higher symptom severity than those without across the 2 visits (22.1 ± 14.3 vs 14.6 ± 12.5; P < 0.001). There was no significant difference in the change in symptom severity between visits among those who received [median = 9-point improvement; interquartile range (IQR) = 1-14] and did not (median = 9, IQR = 2-18) receive a melatonin prescription (P = 0.80). CONCLUSIONS: Sleep problems among pediatric patients within 2 weeks of concussion are associated with more severe symptoms. Melatonin prescription was not associated with faster symptom recovery.

Sports participation volume and psychosocial outcomes among healthy high school athletes.

OBJECTIVES: We assessed the association between hours/week of sports participation and psychosocial outcomes among high school athletes. We hypothesized that more hours of participation would be associated with the lower levels of anxiety and depressive symptoms. METHODS: Participants completed the Patient-reported Outcomes Measurement Information System (PROMIS) Pediatric Profile 25 quality of life and other questionnaires to assess sports participation, socioeconomic status, and health history. We evaluated the multivariable relationship between hours/week in sport and PROMIS scores while adjusting for the independent effect of age and varsity team status. RESULTS: A total of 230 high school athletes participated in this study (mean=15.4±1.2 years of age). More hours/week playing sports were significantly associated with the lower levels of depressive symptoms (coefficient=-0.073, 95% CI=-0.137, -0.010; P=0.02). Sports participation was not significantly associated with any other psychosocial domain scores on the PROMIS questionnaire. CONCLUSION: More hours of sports participation were significantly associated with the lower depressive symptoms, but no other psychosocial domain. While our findings are cross-sectional, sport participation may play a role in attenuating symptoms of depression in high school athletes. RELEVANCE FOR PATIENTS: Sports participation may play a beneficial role in lessening depressive symptoms among healthy high school students.

Returning to Climb after Epiphyseal Finger Stress Fracture.

The number of youth participating in rock climbing has increased over the years. Finger stress epiphyseal fractures are the most common injury among youth climbers. These injuries tend to occur around puberty because this is when the physis is most vulnerable to injury. Additionally, it has been found that intensive finger training (campus boarding, a previously known risk factor for epiphyseal fractures) during adolescence can lead to early-onset osteoarthritis of the hand up to a decade later. There is currently a lack of a return-to-climb protocol for youth climbers following a repetitive stress epiphyseal fracture. Because of this gap in the literature, our purpose was to create a structured return-to-play protocol specific to youth climbers who sustained an epiphyseal fracture to the finger. By establishing these guidelines, medical professionals and coaches may be able to guide their athlete to gradually and safely return to sport.

Early physical activity and clinical outcomes following pediatric sport-related concussion.

OBJECTIVE: The objective of the study was to evaluate the clinical outcomes among patients who did and did not report engaging in early physical activity (PA) following sport-related concussion. METHODS: We evaluated pediatric patients seen within 21 days of concussion. The independent variable was early PA engagement (since the injury and before initial clinical evaluation). Dependent variables included demographics, injury details, medical history, Health and Behavior Inventory (HBI) score, and balance, vestibular, and oculomotor function tests. RESULTS: We examined data from 575 pediatric patients: Sixty-nine (12%) reported engaging in early PA (mean age=14.3±2.4 years; 30% female). The no PA group (mean age=14.5±2.4 years; 35% female) had significantly longer symptom resolution times than the early PA group (median= 16 [interquartile range (IQR)=8-24] vs. 10.5 [IQR=4-17] days; p=0.02). When controlling for pre-existing headache history and time from injury-evaluation time, the early PA group demonstrated lower odds of reporting current headache (adjusted odds ratio=0.14; 95% CI=0.07, 0.26), and reported lower symptom frequency ratings than the no PA group (b=-5.58, 95% CI=-8.94, -2.22). CONCLUSIONS: Patients who did not engage in early PA had longer symptom duration, greater odds of post-injury headache, and greater symptoms at initial clinical evaluation. We cannot determine if patients engaged in early PA due to the lower symptom burden and higher functioning at the time of assessment, or if early PA positively affected outcomes. However, as early PA was associated with better post-injury outcomes, clinicians may consider supervised and structured early PA programs as a method to improve clinical outcomes following concussion. RELEVANCE FOR PATIENTS: Children and adolescents who were engaged in PA after concussion presented to a clinic with less severe symptoms and had symptoms that resolved sooner compared to those who did not engage in early PA after concussion.

The Association of Finger Growth Plate Injury History and Speed Climbing in Youth Competition Climbers.

INTRODUCTION: Finger growth plate injuries are the most common injury among youth climbers, and the association between these injuries and speed climbing, a mandatory discipline in the 2021 Olympics, has not been examined previously. Our primary purpose was to examine the demographic and training characteristics of adolescent competition climbers who reported a history of a finger growth plate injury compared to those who did not report a history of a finger growth plate injury. Our secondary purpose was to determine whether training characteristics differed between adolescent competition climbers who did and did not report speed climbing. METHODS: Our study was a cross-sectional study design. We surveyed adolescent climbers who competed in the 2017 USA Climbing Sport and Speed Youth National Championships. Questions assessed climbing injury history and current rock-climbing training characteristics. RESULTS: Two-hundred sixty-seven adolescent competition climbers, 14±3 (9-18) y of age (mean±SD with range), completed the survey. Those with a history of a finger growth plate injury reported greater approximate time spent speed climbing throughout the year (ß=1.28, 95% CI 0.11-2.46, P=0.032) and training regularly on the International Federation of Sport Climbing speed wall (adjusted odds ratio=3.95, 95% CI 1.14-13.7, P=0.031). CONCLUSIONS: Training regularly at practices on the speed wall was associated with a self-reported history of finger growth plate injuries among elite youth competition climbers. Speed climbing should be limited, especially during periods of rapid growth.

Presence of Neck or Shoulder Pain Following Sport-Related Concussion Negatively Influences Recovery.

Our objective was to examine the effect of current neck or shoulder pain on concussion outcomes. Variables included symptom resolution and return-to-sport time, symptom severity, amount of school missed, and sleep disturbances. Three hundred twelve patients (37% female; median age = 15.0 years; evaluated median = 9 days postinjury) reported experiencing current neck or shoulder pain at initial evaluation, and 268 did not (31% female; median age = 14.7 years; evaluated median = 8 days postinjury). Neck or shoulder pain was associated with longer symptom resolution time (ß = 6.38, 95% confidence interval [CI] = 2.44, 10.31; P = .002), more severe symptoms (ß = 7.06, 95% CI = 4.91, 9.21; P < .001), and greater odds of missing >5 days of school (adjusted odds ratio [aOR] = 1.89, 95% CI = 1.23, 2.93; P = .004), and postinjury sleep problems (aOR = 2.20, 95% CI = 1.51, 3.21; P < .001). Experiencing neck or shoulder pain during the initial postinjury clinical evaluation was associated with worsened clinical outcomes. Clinicians may consider referral to early rehabilitation following concussion among those who report neck or shoulder pain.

Are Adolescent Climbers Aware of the Most Common Youth Climbing Injury and Safe Training Practices?

Finger growth plate injuries are the most common youth climbing injuries. The purpose of our study was to understand youth awareness of the most common youth climbing injury and safe training practices. We surveyed climbers, ages eight to 18 years old, at the 2017 USA Climbing Sport and Speed Youth National Championships. A total of 267 climbers completed the survey (mean age = 14 ± 2.7 years; 52% male). The A2 pulley injury was reported as the most common youth climbing injury by the largest portion of participants, 36%. The second most commonly identified injury was at the growth plate of the finger, 15% of participants, which was reported as significantly less than the A2 pulley injury, p < 0.001. Six percent of climbers reported the correct safe age to start double dyno campus board training. Roughly 18% of athletes identified growth plate injuries exclusively as a stress fracture, whereas 29.2% of those climbers self-reported as informed about finger growth plate injuries, but only 7.4% of climbers who self-reported as uninformed answered this question correctly. Misperceptions about skeletally-immature climbing injuries are prevalent amongst youth climbers. Education on the prevalence of finger growth plate injuries and the scarcity of A2 pulley injuries in youth climbers can increase diagnostic accuracy, improve care, and reduce long-term complications.

Concussion-Symptom Rating Correlation Between Pediatric Patients and Their Parents.

CONTEXT: Understanding how parents and their children perceive concussion symptoms may provide insights into optimal concussion-management strategies. OBJECTIVE: To examine patient-parent correlations and agreement on concussion-symptom ratings, to identify differences in patient-parent symptom reporting between children (8-12 years of age) and adolescents (13-18 years of age), and to evaluate the correlation between patient and parent initial symptom-severity ratings with symptom duration and return-to-play time. DESIGN: Cross-sectional study. SETTING: Primary care sports medicine clinic. PATIENTS OR OTHER PARTICIPANTS: A total of 267 patients aged 8 to 18 years seen for care within 21 days of sustaining a concussion. Patients were classified as children (n = 65; age = 11.3 ± 1.4 years; age range, 8-12 years) or adolescents (n = 202; age = 15.5 ± 1.4 years; age range, 13-18 years). MAIN OUTCOME MEASURE(S): Each patient and his or her parent (or legal guardian) completed a concussion-symptom-frequency inventory, the Health and Behavior Inventory (HBI), at the initial postinjury examination. Patients were followed until they no longer reported concussion symptoms (symptom-resolution time) and were allowed to return to unrestricted sport participation (return-to-play time). RESULTS: At the initial examination (8.9 ± 5.2 days postinjury), the symptom-frequency correlation between children and their parents was high (rs = 0.88; 95% confidence interval [CI] = 0.80, 0.95). Adolescents' symptom-frequency reports were also highly correlated with those of their parents (rs = 0.78; 95% CI = 0.71, 0.85). However, the child-parent correlation was higher than the adolescent-parent agreement (z = 2.21, P = .03). Greater patient (consolidated child and adolescent) HBI ratings were associated with longer symptom-resolution times (coefficient = 0.019; 95% CI = 0.007, 0.031; P = .002) and longer return-to-play times (coefficient = 0.012; 95% CI = 0.002, 0.022; P = .02), whereas parent HBI ratings were not. CONCLUSIONS: Our findings may help to set expectations regarding concussion-symptom durations and return-to-play timing for pediatric patients and their families. Given the patient-parent correlations in our sample, substantial reporting discrepancies between patients and their parents may be a relevant factor for clinicians to investigate further during concussion evaluations.
