The Relationship

The purpose of this study is to demonstrate whether neurocognitive evaluation can confirm the association between neurocognitive level and postural control and to analyze the relationship between neurocognitive level and acute musculoskeletal injury in male non-net sports athletes. Seventy-seven male non-net sports athletes participated in this study. The Standardized Assessment of Concussion (SAC), Landing Error Scoring System (LESS), Balance Error Scoring System (BESS), and Star Excursion Balance Test (SEBT) were used for testing; we collected data related to injury history for six months after testing. Pearson’s correlation analysis, logistic regression, and the independent sample t-test were used for statistical analysis. The correlation between SAC and SEBT results was weak to moderate (p < 0.05). Eleven of the seventy-seven participants experienced acute lower limb injuries. SAC, LESS, BESS, and SEBT results have no effect on the occurrence of acute lower extremity injuries (p > 0.05) and were not statistically different between the injured and non-injured groups (p > 0.05). Therefore, using the SAC score alone to determine the risk factor of lower extremity injuries, except in the use of assessment after a concussion, should be cautioned against.

Background: Artistic competitive gymnastics results in a wide, unique spectrum of injuries. Due to the high number of injuries and the current lack of research related to pre-competitive testing in adolescent gymnasts, it is crucial to find a method to predict the likelihood of an athlete sustaining an in-season injury. Purpose: The purpose of this study was to 1) describe the frequency and type of pre-season and in-season injuries, 2) determine if there were differences in physical performance tests between those who had a lower extremity (LE) injury in-season and those who did not, and 3) determine if there were differences in age, level, sex, BMI, sport modifications, previous injury, and current injury between those who had a LE injury and those who didn’t. Methods: Thirty-seven adolescent gymnasts (average age: 12.81 years) were included with levels ranging from 5 (novice) to 10 (elite). Participants (15 males and 22 females) were surveyed for previous and current injury. The athletes completed a performance battery before the competition season including: Lower Quarter Y-Balance Test (LQYBT), Closed Kinetic Chain dorsiflexion (CKCDF), single hop (SH), triple hop (TH), and the Functional Movement Screen (FMS). Follow-up data was collected at the end of the competitive season for comparison. The data was analyzed using descriptive methods and comparative analyses including chi-square and independent t-tests with an alpha level set at .05. Results: Sixty-five percent reported an injury in the last year and seventy-eight percent reported pre-season injuries at testing day. The most common location for pre-season injury was the ankle/foot (24% and 31% respectively). There were no differences between injured and non-injured athletes when comparing asymmetries in CKCDF, LQYBT posteromedial or posterolateral reach, hop testing, or FMS. The LQYBT-anterior scores were significantly different at p=.049 between the injured versus uninjured groups, with 91% of the in-season injury group having a difference <4cm. Similarly, the LQYBT-composite score using a cut-off of 95% was significant at p=.043 with those >95% category being more likely to get injured. There were no significant differences in demographic information comparing injury occurrence. Conclusion: The tested physical performance battery may be useful in tracking gymnasts over time, but may not be beneficial in forecasting injuries in a sport with high percentages of acute injuries. The collected injury volume may not be reflective of a standard season as COVID-19 decreased the number of competitions. Additional research to identify athletes at risk for injury requires further investigation.

AIMS: Based on the limited evidence available about the intrinsic factors causing lower extremity injuries among Malaysian badminton players, this study was aimed to determine the relationship of demographic and physical characteristics to lower extremity injuries in young badminton players.METHODS: A cross-sectional study included badminton players between 14 and 24 years of age, categorized into case and control groups. Participants diagnosed with lower limb injuries were designated as cases, and those with no reported injuries were designated as controls. Personal information including demographic data, level of athlete and injury history was collected using a questionnaire. Independent t-test was used to analyze the differences between intrinsic characteristics in cases and controls. Pearson's χ2 was applied to evaluate the association between risk factors and general lower limb injuries, knee injuries and ankle injuries, with 95% confidence interval (CI). A p value of ≤0.05 was considered significant.RESULTS: A total of 106 young badminton players (83 males, 23 females) were recruited, of whom 42 participants were allocated as the case group, and 64 participants were allocated as the control group. A total of 60 lower extremity injuries were reported among the 42 players of the case group. The overall mean age of the sample was 18.7±5 years (minimum 14 years and maximum 24 years). Mean age of the participants in the case group was 16.92±2.99 years. The most common injuries reported were ankle joint injuries, followed by knee and hip injuries. Participants of the younger age group (14-19 years old) were found to have a higher risk for lower extremity injures compared to those of the older age group (20-24 years old) (odds ratio [OR], 3.39; 95%CI, 1.15-10.01; p=0.023). Increased true limb length discrepancy was identified among the participants with lower extremity injuries (OR, 4.57, 95%CI, 1.2-17.24; p=0.016) and this discrepancy was strongly associated with ankle injuries (OR, 7.25; 95%CI, 1.85-28.57; p=0.002). There was no significant relationship between lower extremity injuries and gender, limb dominance or Q-angle.CONCLUSIONS: Lower extremity injuries in young badminton players were predominantly located in ankle and knee joints. Younger age and increase in true limb length discrepancy were identified as risk factors for lower extremity injuries in the study sample.

PURPOSE: The purpose of this investigation is to examine the relationship between forced sedentariness attributed to the management of a lower extremity injury and change in BMI in pediatric patients. INTRODUCTION: Over the past 30 years, childhood obesity has significantly increased. Lack of physical activity and rising levels of sedentary living are associated with rising childhood obesity. As the effects of childhood obesity are long lasting, it is important to characterize childhood conditions that lead to increases in BMI. Traumatic lower extremity injuries in children commonly result in casting and forced immobilization. Children and adolescents who cease physical activity at a younger age are at a higher risk for weight gain and inactive lifestyles as adults. Presently, the data examining short term and longitudinal effects of injury on weight changes are lacking. Therefore, the purpose of this investigation is to examine the relationship between forced sedentariness attributed to the management of a lower extremity injury and change in BMI in pediatric patients. METHODS: Eighty eight subjects aged 5 to 18 with lower extremity fractures managed with non-weight bearing for a minimum of 6 weeks were identified. This group was compared to a cohort of controls, who presented to the pediatric orthopaedic clinic for upper extremity injuries. For each subject, BMI was calculated from height and weight data obtained at each clinic visit for which the data were available for a minimum of 6 months. Percent change in BMI was then calculated and compared between the lower extremity injury group and controls utilizing ANOVA. Logistic regression was then performed to determine if age, gender, and undergoing surgery were correleated with a BMI change of greater than 10%. RESULTS: The results of initial ANOVA analysis demonstrated no difference in BMI trends between children with lower extremity injuries and controls. On average, both groups showed a modest increase in BMI over time (lower extremity injuries = 3.40%, controls = 3.23%). Logistic analysis of the lower extremity revealed male gender to be associated with a 10% increase in BMI during the study period, though this was not significant (p = 0.153) CONCLUSIONS: Our investigation yielded a negative result. As there is limited literature on BMI trends in children, our power calculation may have underestimated the subjects needed to demonstrate a statistically significant difference between groups. SIGNIFICANCE: The increases observed in both groups may indicate that the experience of being injured is associated with increases in BMI regardless of the location of injury. Further investigation would involve assessing BMI trends prospectively to identify opportunities to obviate possible weight gain with injury.

Background of Study: Females generally have a 6-8 times higher risk for lower extremity injury compared to male counterparts due to biomechanical differences and/or poor landing strategies. In recent years, a great deal of focus has been placed on prevention and reduction of non-contact lower extremity injuries. This has spurred the development of assessment methods to determine how athletes move and tools with which those motions are measured. Efforts have been made to measure and quantify movement strategies, which have given rise to multiple movement tests and measurement devices. One approach is the use of wearable technologies used in conjunction with a movement screening. Objective: Demonstrate a practical approach of using wearable technologies to guide training regimens in a population of female athletes that would be considered at risk for lower extremity injuries. Methods: A cohort of Division I female volleyball athletes were screened using wearable technology then assigned an intervention based on screening results. Comparisons were made between injury rates during the season when the intervention was applied compared to previous seasons. Results: All lower extremity injury rates were reduced after the intervention was applied. Conclusions: The use of wearable technology aids in quantifying movement to then assign a strategic intervention to reduce injuries in an at risk athletic population.

Context: The high incidence of lower limb injuries associated with physical exercises in military conscripts suggests that fatigue may be a risk factor for injuries. Researchers have hypothesized that lower limb injuries may be related to altered ankle and knee joint position sense (JPS) due to fatigue. Objective: To evaluate if military exercises could alter JPS and to examine the possible relation of JPS to future lower extremity injuries in military service. Design: Cohort study. Setting: Laboratory. Patients or Other Participants: A total of 50 male conscripts (age = 21.4 ± 2.3 years, height = 174.5 ± 6.4 cm, mass = 73.1 ± 6.3 kg) from a unique military base were recruited randomly. Main Outcome Measure(s): Participants performed 8 weeks of physical activities at the beginning of a military course. In the first part of the study, we instructed participants to recognize predetermined positions before and after military exercises so we could examine the effects of military exercise on JPS. The averages of the absolute error and the variable error of 3 trials were recorded. We collected data on the frequency of lower extremity injuries over 8 weeks. Next, the participants were divided into 2 groups: injured and uninjured. Separate 2 × 2 × 2 (group-by-time-by-joint) mixed-model analyses of variance were used to determine main effects and interactions of these factors for each JPS measure. In the second part of the study, we examined whether the effects of fatigue on JPS were related to the development of injury during an 8-week training program. We calculated Hedges effect sizes for JPS changes postexercise in each group and compared change scores between groups. Results: We found group-by-time interactions for all JPS variables (F range = 2.86–4.05, P &lt; .01). All participants showed increases in JPS errors postexercise (P &lt; .01), but the injured group had greater changes for all the variables (P &lt; .01). Conclusions: Military conscripts who sustained lower extremity injuries during an 8-week military exercise program had greater loss of JPS acuity than conscripts who did not sustain injuries. The changes in JPS found after 1 bout of exercise may have predictive ability for future musculoskeletal injuries.

Context: The Landing Error Scoring System (LESS) is a clinical tool often used in research and practice to identify athletes presenting high injury-risk biomechanical patterns during a jump-landing task. Objective: To systematically review the literature addressing the psychometric properties of the LESS. Data Sources: Three electronic databases (PubMed, Web of Science, and Scopus) were searched on March 28, 2018, using the term “Landing Error Scoring System.” Study Selection: All studies using the LESS as main outcome measure and addressing its reliability, validity against motion capture system, and predictive validity were included. Original English-language studies published in peer-reviewed journals were reviewed. Studies using modified versions of the LESS were excluded. Study Design: Systematic literature review. Level of Evidence: Level 4. Data Extraction: Study design, population, LESS testing procedures, LESS scores, statistical analysis, and main results were extracted from studies using a standardized template. Results: Ten studies met inclusion criteria and were appraised using Newcastle-Ottawa Quality Assessment Scale adapted for cross-sectional studies. The overall LESS score demonstrated good-to-excellent intrarater (intraclass correlation coefficient [ICC], 0.82-0.99), interrater (ICC, 0.83-0.92), and intersession reliability (ICC, 0.81). The validity of the overall LESS score against 3-dimensional jump-landing biomechanics was good when individuals were divided into 4 quartiles based on LESS scores. The validity of individual LESS items versus 3-dimensional motion capture data was moderate-to-excellent for most of the items addressing key risk factors for anterior cruciate ligament (ACL) injury. The predictive value of the LESS for ACL and other noncontact lower-extremity injuries remains uncertain based on the current scientific evidence. Conclusion: The LESS is a reliable screening tool. However, further work is needed to improve the LESS validity against motion capture system and confirm its predictive validity for ACL and other noncontact lower-extremity injuries.

Context:There is a need for reliable clinical assessment tools that can be used to identify individuals who may be at risk for injury. The Landing Error Scoring System (LESS) is a reliable and valid clinical assessment tool that was developed to identify individuals at risk for lower extremity injuries. One limitation of this tool is that it cannot be assessed in real time and requires the use of video cameras.Objective:To determine the interrater reliability of a real-time version of the LESS, the LESS-RT.Design:Reliability study.Setting:Controlled research laboratory.Participants:43 healthy volunteers (24 women, 19 men) between the ages of 18 and 23.Intervention:The LESS-RT evaluates 10 jump-landing characteristics that may predispose an individual to lower extremity injuries. Two sets of raters used the LESS-RT to evaluate participants as they performed 4 trials of a jump-landing task.Main Outcome Measures:Intraclass correlation coefficient (ICC2,1) values for the final composite score of the LESS-RT were calculated to assess interrater reliability of the LESS-RT.Results:Interrater reliability (ICC2,1) for the LESS-RT ranged from .72 to .81 with standard error of measurements ranging from .69 to .79.Conclusions:The LESS-RT is a quick, easy, and reliable clinical assessment tool that may be used by clinicians to identify individuals who may be at risk for lower extremity injuries.

Objectives: NCAA Division I beach volleyball is a recently introduced sport that has been played for 3 seasons to date. Since the introduction of this new level of athletic participation for women’s’ beach volleyball, no study has been performed to compare the injury patterns between court and sand volleyball playing surfaces. The goal of this study is to compare the injury patterns and incidence in women’s collegiate court and beach volleyball in order to aid trainers, coaches and medical staff in effectively preparing and treating these collegiate athletes. Methods: A 3 year, retrospective review of all training room injury reports were analyzed for both beach and court volleyball from the 2015 through 2017 seasons. Non-athletic injuries or illness were excluded from analysis. Standardized injury rates for beach and court surfaces were calculated by normalizing the total number of injuries by the number of athletes and sets played. To compare the injury patterns among court versus beach volleyball players, injuries were categorized into one of six body regions (abdomen, lower extremity, upper extremity, thorax, head, and back). The proportion of injuries to each of these regions by playing surface was then calculated to compare injury patterns by playing surface. Chi-squared test and odds ratios were used to compare injury rates. Results: Between 2015 and 2017, 90 court volleyball injuries were recorded, while 49 beach volleyball injuries were recorded in the same time period. Court volleyball players had nearly quadruple the injury rate when compared to beach volleyball players, 0.039 and 0.010 injuries per athlete-set respectively (OR 4.05, 95%CI 2.85-5.76, p<0.0001). Court volleyball players suffered a higher proportion of lower extremity injuries when compared to beach volleyball players (51.5% vs. 12.8% respectively, p=0.004), and beach volleyball players suffered a significantly higher proportion of back injuries when compared to court volleyball players, (23.4% vs. 7.8% respectively, p=0.010). Conclusion: The data suggests a significantly higher incidence of injury for court volleyball players when normalized for gameplay exposure. There were, also significant differences in injury patterns with court volleyball players having a higher proportion of lower extremity injuries and beach volleyball having a higher proportion of back injuries. Recognizing these differences can aid in the establishment of preventative strength and conditioning programs as well as post training treatment protocols for these athletes which may increase both the individuals as well as the teams overall competitive success.
