Injury risk factors related to sport specialization in high school basketball: a prospective study.

CONTEXT: Research that has examined the association between specialization and injury in basketball has been limited to cross-sectional or retrospective studies. OBJECTIVE: To determine whether specialization is a risk factor for injury among high school basketball athletes. DESIGN: Prospective cohort study. SETTING: Basketball players from 12 high schools participating in the National Athletic Treatment, Injury, and Outcomes Network Surveillance Program (NATION-SP) were recruited prior to the 2022-2023 interscholastic basketball season. PATIENTS OR OTHER PARTICIPANTS: 130 athletes (mean age (SD) = 15.6 (1.3); girls' basketball: n=68 (52.3%)). MAIN OUTCOME MEASURES: Participants completed a questionnaire prior to the start of their school basketball season that had questions regarding participation in various specialized sport behaviors. During the basketball season, the school's athletic trainer reported all athletic exposures (AEs) and injuries (regardless of time loss) for participating athletes into NATION-SP. Injury incidence (IR) and incidence rate ratios (IRR) with 95% confidence intervals [95%CI] were calculated for the specialized sport behaviors previously described. RESULTS: There was no difference in injury risk between highly specialized and low specialized athletes (IRR [95%CI]: 1.9 [0.9, 3.7]). Players who participated in basketball year-round were twice as likely to sustain an injury compared to those who did not play year-round (IRR [95%CI]: 2.1 [1.1, 3.6]). Similarly, players who reported participating in basketball skills camps were at increased risk of injury compared to athletes who did not participate in basketball skill camps (IRR [95%CI]: 2.5 [1.2, 5.7]). CONCLUSION: Injury risk related to sport specialization in basketball may be specific to certain behaviors such as year-round play and participation in skills camps. Validated measures of comprehensive sport activity are needed to better measure specialization in youth sports to better determine injury risk related to sport specialization and develop injury prevention programs for basketball athletes.

Organizational Expectations Regarding Documentation Practices in Athletic Training.

CONTEXT: Although guidance is available, no nationally recognized standard exists for medical documentation in athletic training, leaving individual organizations responsible for setting expectations and enforcing policies. Previous research has examined clinician documentation behaviors; however, the supervisor's role in creating policy and procedures, communicating expectations, and ensuring accountability has not been investigated. OBJECTIVE: To investigate supervisor practices regarding support, hindrance, and enforcement of medical documentation standards at an individual organization level. DESIGN: Mixed-methods study. SETTING: Online surveys and follow-up interviews. PATIENTS OR OTHER PARTICIPANTS: We criterion sampled supervising athletic trainers (n = 1107) in National Collegiate Athletic Association member schools. The survey collected responses from 64 participants (age = 43 ± 11 years; years of experience as a supervisor = 12 ± 10; access rate = 9.6%; completion rate = 66.7%), and 12 (age = 35 ± 6 years; years of experience as a supervisor = 8 ± 5) participated in a follow-up interview. DATA COLLECTION AND ANALYSIS: We used measures of central tendency to summarize survey data and the consensual qualitative research approach with a 3-person data analysis team and multiphase process to create a consensus codebook. We established trustworthiness using multiple-analyst triangulation, member checking, and internal and external auditing. RESULTS: Fewer than half of supervisors reported having formal written organization-level documentation policies (n = 45/93, 48%) and procedures (n = 32/93, 34%) and an expected timeline for completing documentation (n = 24/84, 29%). Participants described a framework relative to orienting new and existing employees, communicating policies and procedures, strategies for holding employees accountable, and identifying purpose. Limitations included lack of time, prioritization of other roles and responsibilities, and assumptions of prior training and record quality. CONCLUSION: Despite a lack of clear policies, procedures, expectations, prioritization, and accountability strategies, supervisors still felt confident in their employees' abilities to create complete and accurate records. This highlights a gap between supervisor and employee perceptions, as practicing athletic trainers have reported uncertainty regarding documentation practices in previous studies. Although supervisors perceive high confidence in their employees, clear organization standards, employer prioritization, and mechanisms for accountability surrounding documentation will result in improved patient care delivery, system outcomes, and legal compliance.

The Effects of Dry Needling on Hamstring Range of Motion: A Critically Appraised Topic.

CLINICAL SCENARIO: Hamstring range of motion (ROM) and the influence it has on injury risk is among great discussion in the literature. Hamstring injury may result from hamstring tightness, poor flexibility, or decreased ROM, and many argue that this can be prevented through various intervention strategies. In active populations, risk of further injury, pain, and complications throughout the kinetic chain can occur if minimal hamstring ROM is left untreated. One therapeutic intervention that has been applied to varying parts of the body to help improve function while relieving pain is dry needling (DN). This intervention includes the application of needles to structures to induce responses that might benefit healing and overall stimulation of a neurological response. In this review, the intent is to identify evidence and the effects of DN on hamstring ROM. CLINICAL QUESTION: What are the effects of DN on hamstring ROM? SUMMARY OF KEY FINDINGS: Among total 11 articles, 1 single-blinded randomized controlled trial and 2 double-blinded randomized controlled trials were included in this critically appraised topic. All 3 articles had inconclusive evidence to isolate the application of the DN intervention. There was insufficient evidence to identify if DN independently improved hamstring ROM; however, in combination with interventions such as exercise and stretch plans, there were improvements on ROM. CLINICAL BOTTOM LINE: DN does not significantly increase or decrease the ROM of the hamstrings. When combined with exercise and stretch plans, DN could increase ROM. STRENGTH OF RECOMMENDATION: The grade of B is recommended by the Strength of Recommendation Taxonomy for inconsistent or limited-quality patient-oriented evidence.

Higher Levels of Income and Education are Associated with More Specialized Sport Participation Behaviors: Results from a Representative Sample of Youth Sport Parents from the United States.

Background: While previous studies have examined the impact of family socioeconomic characteristics on a child's sport specialization behaviors, this research has been limited to affluent communities with limited sociodemographic diversity. Hypothesis/Purpose: The purpose of this study was to examine associations of parent income and education with child sport specialization behaviors among a nationally representative sample of youth sport parents in the United States. Study Design: Cross-sectional. Methods: Parents of youth athletes in the United States (n=236, age: 39.2±8.1 years, 57.2% female) were recruited to complete an online questionnaire by Qualtrics Online Samples (Qualtrics, Provo, UT) using a combination of actively managed, double-opt-in market research panels. The questionnaire used for this study consisted of: 1) parent demographics (including parent age, race/ethnicity, biological sex, gender identity, household income, and educational status), and 2) child sport participation characteristics and sport specialization behaviors. Results: Parents who reported an annual household income of $75,001 or more were more likely than parents making less than $75,000 to report that their child participated on an organized club team (OR [95%CI]: 1.94 [1.15-3.27]), participated on multiple organized teams at the same time (OR [95%CI]: 1.85 [1.10-3.11]), or specialized in a single sport (OR [95%CI]: 2.45 [1.45-4.14]). Parents who reported receiving a Bachelor's degree or higher were more likely than parents who did not to report that their child participated on an organized club team (OR [95%CI]: 3.04 [1.78-5.18]), participated on multiple organized teams at the same time (OR [95%CI]: 2.42 [1.43-4.10]), or specialized in a single sport (OR [95%CI]: 1.94 [1.15-3.26]). Conclusions: Thes results suggest that in the modern youth sport culture, family resources may serve as a major determining factor in the type of experiences available for a youth athlete. Level of Evidence: III.

The Impact of the Social Determinants of Health on Athletic Trainer Availability in Indiana Secondary Schools.

CONTEXT: The Social Determinants of Health (SDOH) are circumstances individuals are born, work, and live, that influence health outcomes. Previous research has examined one determinant of economic stability and found disparities in socioeconomic status and athletic trainer availability (AT availability). OBJECTIVE: Examine SDOH characteristics of Indiana secondary schools and AT availability. DESIGN: Cross-sectional study. SETTING: Database secondary analysis. PARTICIPANTS: 426 secondary schools. MAIN OUTCOME MEASURES: All data was collected from publically available databases. The independent variable was AT availability, schools were classified as having a full-time AT (full-time AT), a part-time AT only (part-time AT), or no AT (no AT). The SDOH variables were gathered for each school (school and county-level). Data were summarized using measures of central tendencies, one-way ANOVAs, and Kruskal-Wallis tests. RESULTS: School enrollment was larger in schools with greater AT availability (p<.001). The proportion of non-white students was greater in schools with more AT availability (p=0.002). There was greater AT availability in counties with higher graduation rates (p=0.03). Post-hoc comparisons revealed significant differences in graduation rate between part-time AT and no AT schools (p=0.04). Schools with less AT availability were located in counties with a slightly higher percentage of the population uninsured (p=0.02). Schools with greater AT availability were located in counties with a higher ratio of population to primary care physicians (p=0.03). Schools with less AT availability were located in counties with higher population experiencing severe housing problems (p=0.02). There were no significant differences in AT availability based on the three social and community context variables (p>0.05). CONCLUSIONS: We found differences in AT availability and a different SDOH characteristics at the secondary school-level. There was less AT availability where high school graduation rates and population of primary care providers are lower. Strategies should be implemented to improve access to athletic health care in under-resourced communities.

The Knowledge and Use of the International Classification of Functioning, Disability and Health (ICF) Framework in Athletic Training.

In 2015, the Strategic Alliance adopted the International Classification of Functioning, Disability, and Health (ICF) as the disablement model framework for delivery of and communication about patient care in athletic training. The purpose of this study was to examine athletic trainers' familiarity, knowledge, application, and implementation of the ICF framework. We used a cross-sectional online survey with 185 athletic trainers (age = 35 ± 9 y), which included 32 items focused on familiarity, knowledge, application, and implementation of the ICF framework. Most participants (n = 96, 51.9%) reported never learning about the ICF framework. During the knowledge assessment, participants scored 4.3 ± 2.7 out of 8, which is equivalent to 53.7%. For the sorting assessment, participants scored 10.9 ± 3.9 out of 18, which is equivalent to 60.5%. On the implementation matrix, the most frequently reported ICF tasks elicited by the athletic trainers included neuromusculoskeletal and movement, structure related to movement, and mobility. The most common 'never elicited' ICF tasks included voice and speech, sexual orientation, and structures related to genitourinary and reproductive system. Deficits related to the ICF framework exist. Athletic trainers reported low implementation across all ICF categories. The decision to not elicit information on these areas of health may reduce the ability to provide patient-centered healthcare.

Athletic Trainer's Varying Levels of Awareness and Use of Disablement Model Frameworks: A Qualitative Study.

In healthcare, disablement model frameworks aim to improve the delivery of patient-centered care through the recognition of patient factors beyond impairments, restrictions, and limitations, which include personal, environmental, and societal factors. Such benefits translate directly to athletic healthcare providing a mechanism for athletic trainers (ATs), as well as other healthcare professionals, to ensure that all aspects of the patient are managed prior to returning to work or sport. The purpose of this study was to investigate ATs recognition and use of disablement frameworks in current clinical practice. We used criterion sampling to identify ATs who were currently practicing from a random sample of ATs that participated in a related cross-sectional survey. A total of 13 participants engaged in an online, audio-only, semi-structured interview that was audio-recorded and transcribed verbatim. A consensual qualitative research (CQR) approach was used to analyze the data. A coding team of three individuals used a multi-phase process to construct a consensus codebook that identified common domains and categories among the participants' responses. Four domains emerged regarding ATs' experiences and recognition of disablement model frameworks. The first three domains were related to the application of disablement model frameworks: (1) patient-centered care, (2) limitations and impairments, and (3) environment and support. Participants described varying degrees of competence and consciousness regarding these domains. The fourth domain related to participants' exposure to disablement model frameworks through formal or informal experiences. Findings suggest that ATs largely demonstrate unconscious incompetence regarding the use of disablement frameworks in clinical practice.

Differences in Access to Athletic Trainers in Public Secondary Schools Based on Socioeconomic Status.

CONTEXT: Significant health care disparities exist in the United States based on socioeconomic status (SES), but the role SES has in secondary school athletes' access to athletic training services has not been examined on a national scale. OBJECTIVE: To identify differences in access to athletic training services in public secondary schools based on school SES. DESIGN: Cross-sectional study. SETTING: Database secondary analysis. PATIENTS OR OTHER PARTICIPANTS: Data for 3482 public high schools. MAIN OUTCOME MEASURE(S): Data were gathered from the Athletic Training Locations and Services (ATLAS) database, US Census Bureau, and National Center for Education Statistics. We included schools from 5 states with the highest, middle, and lowest poverty percentages (15 states total) and collected county median household income, percentage of students eligible for free or reduced-price lunch, race and ethnicity demographics, and access to athletic training services (full-time athletic trainer [AT], part-time AT only, no AT) for each school. Data were summarized in means, SDs, medians, interquartile ranges (IQRs), frequencies and proportions, 1-way analyses of variance, and Kruskal-Wallis tests. RESULTS: Differences were present in school SES between schools with full-time, part-time-only, and no athletic training services. Schools with greater access to athletic training services had fewer students eligible for free or reduced-price lunch (full time: 41.1% ± 22.3%, part time only: 45.8% ± 24.3%, no AT: 52.9% ± 24.9; P < .001). Similarly, county median household income was higher in schools with increased access to athletic training services (full time median [IQR]: $56 026 [$49 085-$64 557], part time only: $52 719 [$45 355-$62 105], and no AT: $49 584 [$41 094-$57 688]; P < .001). CONCLUSIONS: Disparities in SES were seen in access to athletic training services among a national sample of public secondary schools. Access to ATs positively influences student-athletes' health care across several measures. Pilot programs or government funds have been used previously to fund athletic training services and should be considered to ensure equitable access, regardless of school SES.

Parent decision-making regarding youth sport participation during the COVID-19 pandemic.

PURPOSE: To describe youth sport participation behaviors during the COVID-19 pandemic as reported by parents of youth sport athletes, to examine the association of family demographics with the likelihood of children resuming sports, and to qualitatively report the factors influencing parental decision-making regarding youth sport participation during the COVID-19 pandemic. METHODS: A national sample of parents of youth athletes from across the United States (n=236, age: 39.2±8.1 years, 57.2% female) were recruited to complete an online questionnaire by Qualtrics Online Samples (Qualtrics, Provo, UT) using a combination of actively managed, double-opt-in market research panels. The questionnaire focused on changes in child sport participation and family finances as a result of COVID-19 and included both close-ended and open-ended questions. RESULTS: Most parents (63.1%) reported the time their children spent participating in organized youth sports had decreased because of the COVID-19 pandemic. Three-quarters of parents (75.5%) reported that it was likely that their children would fully resume participating in organized youth sports within the next year. Parents whose financial situation was worsened by COVID-19 were less likely to report that their children would resume sports in the upcoming year. Three domains related to parental decision-making emerged from the open-ended responses: safety, fear, and normalcy. CONCLUSIONS: Understanding the factors influencing changes in youth sport participation during the pandemic can allow systems to implement strategies for safe participation in youth sport and physical activity among children. Encouraging participation in outdoor sports with appropriate safety precautions such as masking, social distancing, and hygiene may reduce fear of participation among parents.

The Effectiveness of Dry Needling Combined With Therapeutic Exercises in Treating Tendinopathy Conditions: A Systematic Review.

CONTEXT: Approximately 70,000 Americans miss work annually due to tendinopathies causing pain, disability, and lower quality of life. Various conservative treatments have been demonstrated to improve outcomes in these conditions. Dry needling (DN) and therapeutic exercise are 2 such interventions that have been proposed to be a positive intervention for addressing tendinopathy. OBJECTIVE: To summarize the best available evidence on the use of DN and exercise combined to treat tendinopathy. EVIDENCE ACQUISITION: PubMed, EBSCOHost, and Web of Science were systematically searched from inception to March 2021. Articles were assessed to determine eligibility and evaluated for methodological quality using the PEDro scale. The PRISMA guidelines were used for this review. Inclusion criteria consisted of use of DN in combination with therapeutic exercise, human participants, and active tendinopathy pathology. EVIDENCE SYNTHESIS: Seven studies met the inclusion and exclusion criteria, which averaged 6/11 on the PEDro scale. The level of agreement of evaluators was 94%. Current evidence supports the use of DN combined with therapeutic exercises, especially those including eccentric exercises, can improve pain and function for various tendinopathies. However, limited evidence exists regarding specific therapeutic interventions to be combined with DN. CONCLUSION: There is moderate, level B evidence to suggest the use of DN techniques targeted at the tendon and combined with eccentric therapeutic exercise to improve pain and functional outcomes for tendinopathies.

Psychological Ownership in Athletic Training.

CONTEXT: Psychological ownership (PO) is a state in which an individual feels possession over an object, organization, or entity (eg, PO over the organization where one works, PO over the profession one serves). Understanding PO could provide insight into the "vitality of the profession" as defined in the Prioritized Research Agenda for the Athletic Training Profession. OBJECTIVE: To explore athletic trainers' (ATs') PO over their employing organizations and the athletic training profession. DESIGN: Cross-sectional study. SETTING: Web-based survey. PATIENTS OR OTHER PARTICIPANTS: Clinically practicing ATs who were active members of the National Athletic Trainers' Association. MAIN OUTCOME MEASURE(S): Demographic variables, Psychological Ownership Questionnaire (POQ) scores, and Psychological Ownership Questionnaire for athletic training (POQ-AT) scores were the primary outcomes measured. Descriptive statistics were calculated for the demographic variables, POQ and POQ-AT overall scores, form scores, and dimension scores. Nonparametric tests were used to investigate differences between the POQ and POQ-AT by demographic characteristics. RESULTS: The ATs indicated greater PO over the athletic training profession (Z = -3.45, P = .001) than over their employing organizations. They displayed greater belongingness (Z = -9.51, P < .001) and self-identity (Z = -8.71, P < .001) and less territoriality (Z = -5.52, P < .001) and accountability (Z = -5.33, P < .001) over their profession than their organization. Those ATs who supervised others had higher overall POQ (Mann-Whitney U test = 34 372, P < .001) and overall POQ-AT (U = 36 624, P = .014) scores than ATs who did not supervise others. A difference was evident in overall POQ (Kruskal-Wallis statistical analysis H4 = 20.47, P < .001) and overall POQ-AT (H4 = 21.34, P < .001) scores by years of experience. CONCLUSIONS: Respondents indicated greater PO over their profession than their employing organizations. They demonstrated greater self-identity and belongingness and less territoriality and accountability over the athletic training profession than over their employing organization, suggesting that they were connecting aspirations and accomplishments with the profession but connecting duty and responsibility with their organizations. Years of experience and supervisor status may play roles in the level of organizational PO.

Support Systems and Patient Care Delivery for Nonnative English-Speaking Patients: A Study of Secondary School Athletic Trainers.

CONTEXT: Nonnative English speakers (NNESs) in the United States have more than doubled since 1990, increasing the likelihood of their seeking health care and experiencing language barriers. Language barriers in health care result in ineffective communication, a decreased level of care, and a reduction in overall provider satisfaction. OBJECTIVE: To investigate the experiences of secondary school athletic trainers (ATs) who provided care to patients who were NNESs or communicated with their NNES support systems. DESIGN: Qualitative study. SETTING: Semistructured interviews. PATIENTS OR OTHER PARTICIPANTS: Fifteen secondary school ATs with experience communicating with NNES patients or their support systems. DATA COLLECTION AND ANALYSIS: Participants were interviewed, and the interviews were transcribed. A 3-person data-analysis team used the multiphase, consensual qualitative research approach to develop a consensus codebook with domains and categories. Trustworthiness was established through member checking, multiple-researcher triangulating, and auditing. RESULTS: Four domains emerged from the data: (1) communication, (2) welcoming environment, (3) cultural agility, and (4) resourcefulness. Participants enhanced communication by relying on nonverbal communication, translated resources, and interpreters. The ATs discussed a difference in care delivery based on fluency. Respondents explained efforts to create a welcoming environment by speaking in the NNES's native language, increasing comfort, and serving as an advocate within the health care system. Acknowledging customs, demonstrating respect, and understanding potential fear, shame, or both associated with language barriers were discussed as ways to increase cultural agility. The ATs identified a lack of formal training, which increased their on-the-job training and health information technology use. Participants perceived spending increased amounts of initiation, effort, and time on adaptability while caring for and communicating with NNESs. CONCLUSIONS: The ATs perceived that they had little formal training and, therefore, became more resourceful and increased communication strategies to provide equitable care. Participants indicated that adapting their care to meet cultural needs and creating a welcoming environment for NNESs were important when cultivating a patient-centered experience.

The Examination of Repeated Self-Mobilizations With Movement and Joint Mobilizations on Individuals With Chronic Ankle Instability.

CONTEXT: Chronic ankle instability (CAI) is one of the most common chronic conditions in the world, resulting in millions of dollars contributed to the health care system. Joint mobilizations have been shown to effectively improve patient and disease-specific impairments secondary to CAI. The ability for patients to complete an effective manual therapy intervention without the need for continuous visits to a health care provider can alleviate burdens on the health care system and improve patient satisfaction. OBJECTIVE: To examine the effect of clinician-applied Maitland talocrural joint mobilization and self-mobilization (Self-Mob) on dorsiflexion range of motion (DFROM), dynamic balance, strength, and perceived function in those with CAI. DESIGN: Single-blind randomized trial. SETTING: Research laboratory. PARTICIPANTS: A total of 18 participants (7 males and 11 females; age = 20.78 [2.02] y, height = 67.66 [3.83] cm, limb length = 87.74 [5.05] cm) with self-reported CAI participated. INTERVENTIONS: The participants received 6 interventions over a 2-week period. The participants received either Maitland grade III anterior-to-posterior talocrural joint mobilizations or weight-bearing lunge Self-Mob. Each intervention consisted of four 2-minute sets, with a 1-minute rest between sets. MAIN OUTCOME MEASURES: The DFROM (weight-bearing lunge), dynamic balance (Y-Balance Test), isometric strength, Foot and Ankle Ability Measure Quick, Disablement of the Physically Active modified, Fear Avoidance Beliefs Questionnaire, and Tampa Scale of Kinesiophobia-11 were measured preintervention and postintervention. RESULTS: Dynamic balance, isometric strength, and perceived function significantly improved in both groups at postintervention. The DFROM significantly improved in the Self-Mob group. Higher individual responder rates were demonstrated within the Self-Mob group compared with clinician-applied mobilizations. CONCLUSIONS: Clinician-applied mobilizations and Self-Mobs are effective interventions for improving dynamic balance, isometric strength, and perceived function. Application of Self-Mobs can effectively improve DFROM compared with joint mobilization. Self-Mobs may be an effective intervention to incorporate into a home care plan.

The Evaluation of Joint Mobilization Dosage on Ankle Range of Motion in Individuals With Decreased Dorsiflexion and a History of Ankle Sprain.

CONTEXT: Mulligan's Mobilization with Movement (MWM) is a common intervention used to address dorsiflexion range of motion (DFROM) impairments. However, the treatment dosage of MWMs varies within the literature. OBJECTIVE: The aim of this study was to examine the effect of serial MWM application on DFROM. DESIGN: Repeated-measures cohort. SETTING: A Midwestern University and the surrounding community. PARTICIPANTS: A total of 18 adults (13 females; age = 29 [12.87] y; DFROM = 30.26° [4.60°]) with decrease dorsiflexion (<40°) participated. Inclusion criteria consisted of a history of ≥1 ankle sprain, ≥18 years old, no lower-extremity injury in the last 6 months, and no history of foot/ankle surgery. INTERVENTION: Participants completed a single data collection session consisting of 10 individual sets of MWMs. MAIN OUTCOME MEASURES: DFROM was taken at baseline and immediately after each intervention set (post 1, post 2, … post 10). DFROM was measured with a digital inclinometer on the anterior aspect of the tibia during the weight-bearing lunge test with the knee straight and knee bent. Analysis of variances examined DFROM changes over time. Post hoc analysis evaluated sequential pairwise comparisons and changes from baseline at each time point. RESULTS: Analysis of variance results indicated a significant time main effect for weight-bearing lunge test with knee bent (P < .001) and a nonsignificant effect for weight-bearing lunge test with knee straight (P < .924). Post hoc analysis indicated improvements in the weight-bearing lunge test with knee bent at each timepoint compared with baseline (P < .005). Post 2 improved compared with post 1 (P = .027). No other pairwise sequential comparisons were significant (P > .417). CONCLUSIONS: MWMs significantly improved acute knee bent DFROM and indicated that after 2 sets of MWMs, no further DFROM improvements were identified. Future research should investigate the lasting effects of DFROM improvements with variable MWM dosages.

Proprioceptive Training for the Prevention of Ankle Sprains: An Evidence-Based Review.

Reference: Schiftan GS, Ross LA, Hahne AJ. The effectiveness of proprioceptive training in preventing ankle sprains in sporting populations: a systematic review and meta-analysis. J Sci Med Sport. 2015;18(3):238-244. CLINICAL QUESTION: Does the use of proprioceptive training as a sole intervention decrease the incidence of initial or recurrent ankle sprains in the athletic population? DATA SOURCES: The authors completed a comprehensive literature search of MEDLINE, CINAHL, SPORTDiscus, and Physiotherapy Evidence Database (PEDro) from inception to October 2013. The reference lists of all identified articles were manually screened to obtain additional studies. The following key words were used. Phase 1 population terms were sport*, athlet*, and a combination of the two. Phase 2 intervention terms were propriocept*, balance, neuromusc* adj5 train*, and combinations thereof. Phase 3 condition terms were ankle adj5 sprain*, sprain* adj5 ankle, and combinations thereof. STUDY SELECTION: Studies were included according to the following criteria: (1) the design was a moderate- to high-level randomized controlled trial (>4/10 on the PEDro scale), (2) the participants were physically active (regardless of previous ankle injury), (3) the intervention group received proprioceptive training only, compared with a control group that received no proprioceptive training, and (4) the rate of ankle sprains was reported as a main outcome. Search results were limited to the English language. No restrictions were placed on publication dates. DATA EXTRACTION: Two authors independently reviewed the studies for eligibility. The quality of the pertinent articles was assessed using the PEDro scale, and data were extracted to calculate the relative risk. Data extracted were number of participants, intervention, frequency, duration, follow-up period, and injury rate. MAIN RESULTS: Of the initial 345 studies screened, 7 were included in this review for a total of 3726 participants. Three analyses were conducted for proprioceptive training used (1) to prevent ankle sprains regardless of history (n = 3654), (2) to prevent recurrent ankle sprains (n = 1542), or (3) as the primary preventive measure for those without a history of ankle sprain (n = 946). Regardless of a history of ankle sprain, participants had a reduction in ankle-sprain rates (relative risk [RR] = 0.65, 95% confidence interval [CI] = 0.55, 0.77; numbers needed to treat [NNT] = 17, 95% CI = 11, 33). For individuals with a history of ankle sprains, proprioceptive training demonstrated a reduction in repeat ankle sprains (RR = 0.64, 95% CI = 0.51, 0.81; NNT = 13, 95% CI = 7, 100). Proprioceptive training as a primary preventive measure demonstrated significant results (RR = 0.57, 95% CI = 0.34, 0.97; NNT = 33, 95% CI = 16, 1000). CONCLUSIONS: Proprioceptive training programs were effective in reducing the incidence rates of ankle sprains in the athletic population, including those with and those without a history of ankle sprains.
