Epidemiology of ankle sprain and chronic ankle instability in elite adolescent dancesport athletes

ABSTRACT Background Dancesport is performed in high-heeled shoes. Dancesport athletes may have a higher prevalence and incidence of ankle sprains, which can affect their performance. However, the occurrence of ankle sprains among dancesport athletes remains unclear. This study aimed to determine the prevalence and incidence of ankle sprains among elite dancesport athletes and to investigate the related information. Method We conducted a mixed descriptive epidemiological study (cross-sectional and longitudinal) involving 198 elite adolescent dancesport athletes, using past medical records and questionnaires administered to the participants. Data on the occurrence of ankle sprains among all participants were compiled using medical records and information on injury mechanisms, missed days, severity types, and countermeasures for ankle sprains were collected. The prevalence of chronic ankle instability (CAI) among the participants was assessed using a questionnaire. Following the initial survey, we conducted a one-year follow-up study to investigate the incidence of ankle sprains, incidence rate per 1000 exposure hours, and recurrence of ankle sprains. Result The cross-sectional study and longitudinal study included 198 participants and 92 elite dancesport athletes, respectively. The prevalence of ankle sprains and CAI was 49.5% and 45.1%, respectively. Of all ankle sprains, 88% were medial injuries. The most common injury mechanisms were turning (46.9%) and jumping (46.9%). The average number of missed days due to ankle sprains was 11.2 days. Most injuries were managed with rest, and only one male athlete underwent surgery due to an ankle sprain sustained during dancing. During the one-year follow-up, the incidence of ankle sprains, incidence rate per 1000 exposure hours, and recurrence rate of ankle sprains were 46.6% (male, 41.2%; female, 48.8%), 0.65 ankle sprains/1000 h, and 35.3%, respectively. No sex-related differences were observed. Conclusion It is crucial to focus on the occurrence of ankle sprains and CAI in dancesport athletes with high heels. Future research should clarify the impact of ankle sprains on dancesport performance and develop preventive measures to reduce the incidence and recurrence of these associated injuries.

"Effect of Immersive Virtual Reality in Adjunct to Conventional Physiotherapy on Static Balance, Dynamic Balance and Vertical Jump in Futsal Players with Lateral Ankle Sprain: A Protocol for Randomized Control Trial"

Background As there is high expense of treatment and potential long-term consequences including chronic ankle instability (CAI), lateral ankle sprains (LAS) are common among athletes and represent a substantial healthcare burden. In terms of preventing more injuries and encouraging a full recovery, traditional treatments frequently fall short. Methods At the Department of Sports Physiotherapy, futsal athletes with grade I and grade II lateral ankle sprains will participate in a parallel-group, 1:1 allocation ratio trial. Individuals who fulfil the eligibility requirements will be randomized at random to either the experimental or control group. Conventional physiotherapy treatments will be administered to the control group, and IVR sessions utilizing certain games will be administered to the experimental group in addition to the same therapies. The Y Balance Tool is used to measure dynamic balance, the X Sens MVN system is used to measure vertical jump, and the Balance Error Scoring System (BESS) is used to assess static balance. Result This study aims to offer a new way to improving results for futsal players recovering from lateral ankle sprains by utilizing IVR technology in conjunction with traditional physiotherapy. The results could lead to the creation of more efficient sports-related injury rehabilitation programs, which would improve athlete performance and lessen the incidence of ankle sprains in athletic populations.

Treatment of acute ankle distortion in footballers : Are we doing it particularly right or particularly wrong?

Despite the high incidence of ankle sprains, the ideal treatment is controversial and asignificant percentage of patients who have suffered an ankle sprain never fully recover. Even professional athletes are affected by this post-traumatic complication. There is strong evidence that permanent impairment after an ankle injury is often due to an inadequate rehabilitation and training program and too early return to sport. Therefore, athletes should start acriteria-based rehabilitation after ankle sprain and gradually progress through the programmed activities, including e.g. cryotherapy, edema reduction, optimal load management, range of motion exercises to improve ankle dorsiflexion and digital guidance, stretching of the triceps surae with isometric exercises and strengthening of the peroneus muscles, balance and proprioception training, and bracing/taping. The fact that this is professional sport does not exempt it from consistent, stage-appropriate treatment and acautious increase in load. However, there are anumber of measures and tools that can be used in the intensive care of athletes to improve treatment and results.

Effects of Functional Fatigue Protocol and Visual Information on Postural Control in Patients with Chronic Ankle Instability

Chronic ankle instability (CAI) patients often exhibit postural control deficits and rely on visual information to maintain static balance to compensate for decreased proprioception. Fatigue impairs neuromuscular control, in addition to postural control, in CAI patients. However, whether functional fatiguing exercises alter postural control and sensory organization strategies during single-leg balance tests in CAI patients remains unclear. This study involved a controlled trial on 28 CAI patients in a laboratory setting. Each participant performed a single-leg balance test with eyes open (EO) and eyes closed (EC) before and after a functional fatigue protocol. Two-way repeated-measures ANOVA evaluated fatigue (pre- vs. post-fatigue) × vision (EO vs. EC) interactions for outcome variables. Additionally, paired-sample t-tests examined differences between two conditions (pre- vs. post-fatigue) for time-to-boundary (TTB) minima (%modulation). We found significant interactions between fatigue and vision conditions in ML and AP TTBmeans and AP TTBsds. %Modulations were significantly decreased after fatigue in AP TTBmean, ML TTBsd, and AP TTBsd. In conclusion, static postural control ability decreased after the functional fatigue protocol with EO, but was unchanged with EC. This suggests that decreased balance ability is more pronounced with EO under fatigue due to less visual dependence. This may increase ankle sprain incidence under fatigue.

Medicaid Insurance is Associated With Decreased MRI Use for Ankle Sprains Compared With Private Insurance: A Retrospective Large-database Analysis.

Advanced imaging modalities are expensive, and access to advanced imaging services may vary by socioeconomic factors, creating the potential for unwarranted variations in care. Ankle sprains are a common injury for which variations in MRI use can occur, both via underuse of indicated MRIs (appropriate use) and overuse of nonindicated MRIs (inappropriate use). High-value, equitable healthcare would decrease inappropriate use and increase appropriate use of MRI for this common injury. It is unknown whether socioeconomic factors are associated with underuse of indicated MRIs and overuse of nonindicated MRIs for ankle sprains. Using ankle sprains as a paradigm injury, given their high population incidence, we asked: (1) Does MRI use for ankle sprains vary by insurance type? (2) After controlling for relevant confounding variables, did patients who received an MRI have higher odds of undergoing ankle surgery? Between 2011 and 2019, a total of 6,710,223 patients were entered into the PearlDiver Mariner Patient Records Database with a diagnosis of ankle sprain. We considered patients with continuous enrollment in the database for at least 1 year before and 2 years after the diagnosis as potentially eligible. Based on that, 68% (4,567,106) were eligible; a further 20% (1,372,478) were excluded because of age younger than 18 years, age at least 65 years with Medicaid insurance, or age < 65 years with Medicare insurance. Another 0.1% (9169) had incomplete data, leaving 47% (3,185,459) for analysis here. Patients with Medicaid insurance differed from patients with Medicare Advantage or private insurance with respect to age, gender, region, and comorbidity burden. The primary outcome was ankle MRI occurring within 12 months after diagnosis. The use of ankle surgery after MRI in each cohort was measured as a secondary outcome. We used multivariable logistic regression models to evaluate the association between insurance type and MRI use while adjusting for age, gender, region, and comorbidity burden. Separate multivariable regression models were created to evaluate the association between receiving an MRI and subsequent ankle surgery for each insurance type, adjusting for age, gender, region, and comorbidity burden. Within 12 months of an ankle sprain diagnosis, 1% (3522 of 339,457) of patients with Medicaid, 2% (44,793 of 2,627,288) of patients with private insurance, and 1% (1660 of 218,714) of patients with Medicare Advantage received an MRI. After controlling for age, gender, region, and comorbidity burden, patients with Medicaid had lower odds of receiving an MRI within 12 months after ankle sprain diagnosis than patients with private insurance (odds ratio 0.60 [95% confidence interval 0.57 to 0.62]; p < 0.001). Patients with Medicaid who received an MRI had higher adjusted odds of undergoing subsequent ankle surgery (OR 23 [95% CI 21 to 26]; p < 0.001) than patients with private insurance (OR 12.7 [95% CI 12 to 13]; p < 0.001). Although absolute MRI use was generally low, there was substantial relative variation by insurance type. Given the high incidence of ankle sprains in the general population, these relative differences can translate to tens of thousands of MRIs. Further studies are needed to evaluate the reasons for decreased appropriate MRI use in patients with Medicaid and overuse of MRI in patients with private insurance. The establishment of clinical practice guidelines by orthopaedic professional societies and more stringent gatekeeping for MRI use by health insurers could reduce unwarranted variations in MRI use.

Epidemiology and management of ankle sprain injuries over seven seasons in an elite professional ballet company

ObjectivesTo investigate the epidemiology and management of ankle ligament sprains over seven seasons in a professional ballet company. DesignDescriptive epidemiology study. MethodsMedical attention injury, time-loss injury, and exposure data pertaining to 140 professional ballet dancers were prospectively recorded by Chartered Physiotherapists over seven seasons (2015/16–2021/22); a period including the COVID-19 global pandemic. ResultsSixty-nine ankle sprains (46 time-loss) in 45 dancers (32 %) were recorded: 51 sprains were classified as grade I, 15 were classified as grade II, and three were classified as grade III; 53 sprains affected only one ligament, whilst 16 were multi-ligament sprains. For time-loss injuries, median time-loss durations varied by grading (I - 31 days, II - 54 days, and III - 147 days) and the number of ligaments affected (one - 31 days, two - 54 days, three - 134 days, four - 137 days), with time-loss ranging from 1 to 188 days. Of the 46 time-loss ankle sprains, eight were mild, nine were moderate, and 29 were severe. The incidence rate (injuries·1000 h−1) of medical attention ankle sprains was 0.073 (95 % CI: 0.046 to 0.117) in male dancers and 0.101 (95 % CI: 0.069 to 0.148) in female dancers, and the incidence of time-loss ankle sprains was 0.044 (95 % CI: 0.024 to 0.080) in male dancers and 0.064 (95 % CI: 0.040 to 0.103) in female dancers. No significant effect of sex was observed on either medical attention (p = .304) or time-loss (p = .327) ankle sprain incidence rates. Ten percent of dancers sustained multiple sprains across the seven seasons. Fifty and 39 % of ankle sprains in female and male dancers, respectively, were preceded by a history of ankle sprains. Jumping and landing (30 sprains) and non-dance movements (16 sprains) were the most common inciting movements. Bone bruising and synovitis were the most common concurrent pathologies. ConclusionsAnkle sprains placed a considerable burden on the ballet company studied. These time-loss durations specified by number and grade of ligament sprain, injury history, and secondary pathologies can guide return-to-dance rehabilitation pathways.

The impact of the menstrual cycle on orthopaedic sports injuries in female athletes.

There is a disparity in sport-related injuries between sexes, with females sustaining non-contact musculoskeletal injuries at a higher rate. Anterior cruciate ligament ruptures are between two and eight times more common than in males, and females also have a higher incidence of ankle sprains, patellofemoral pain, and bone stress injuries. The sequelae of such injuries can be devastating to an athlete, resulting in time out of sport, surgery, and the early onset of osteoarthritis. It is important to identify the causes of this disparity and introduce prevention programmes to reduce the incidence of these injuries. A natural difference reflects the effect of reproductive hormones in females, which have receptors in certain musculoskeletal tissues. Relaxin increases ligamentous laxity. Oestrogen decreases the synthesis of collagen and progesterone does the opposite. Insufficient diet and intensive training can lead to menstrual irregularities, which are common in female athletes and result in injury, whereas oral contraception may have a protective effect against certain injuries. It is important for coaches, physiotherapists, nutritionists, doctors, and athletes to be aware of these issues and to implement preventive measures. This annotation explores the relationship between the menstrual cycle and orthopaedic sports injuries in pre-menopausal females, and proposes recommendations to mitigate the risk of sustaining these injuries.

The incidence rate of ACL injuries and ankle sprains in basketball players: A systematic review and meta-analysis.

To quantify the incidence rate of anterior cruciate ligament (ACL) injuries and ankle sprains according to player sex, playing level, and exposure setting (training vs. games) in basketball players. PubMed, MEDLINE, Google Scholar, and ScienceDirect were searched. Only studies reporting the number of ACL injuries and/or ankle sprains alongside the number of athlete-exposures (training sessions and/or games) in basketball players were included. Thirty studies (17 reporting ACL injuries and 16 reporting ankle sprains) were included in the meta-analysis. Higher (p < 0.05) ACL injury incidence rates per 1000 athlete-exposures were recorded in females (female: 0.20 95% confidence intervals [0.16-0.25]; male: 0.07 [0.05-0.08]; female-to-male ratio: 3.33 [3.10-3.57]), in players competing at higher playing levels (amateur: 0.06 [0.04-0.09]; intermediate: 0.16 [0.13-0.20]; elite: 0.25 [0.14-0.64]), and in games (games: female, 0.27 [0.21-0.32]; male, 0.06 [0.03-0.08]; training: female, 0.03 [0.02-0.05]; male: 0.01 [0.00-0.02]; game-to-training ratio: 7.90 [4.88-12.91]). Higher (p < 0.05) ankle sprain incidence rates per 1000 athlete-exposures were observed in males (female: 0.82 [0.61-1.03]; male: 0.90 [0.61-1.19]; female-to-male ratio: 0.91 [0.83-0.99]), in players competing at higher playing levels (amateur: 0.54 [0.51-0.57]; intermediate: 1.12 [1.00-1.24]; elite: 1.87 [1.29-2.46]), and in games (games: 2.51 [1.85-3.16]; training: 0.80 [0.52-0.80]; game-to-training ratio: 2.77 [2.35-3.26]). According to player sex, ACL injury incidence rate is higher in females, while ankle sprain incidence rate is greater in males. ACL injury and ankle sprain incidence rates are greater in players competing at higher playing levels and during games compared to training.

Effects of core muscle strengthening on pain and dynamic balance among professional basketball players with ankle sprain

Basketball is a contact sports that requires offense and defense. Ankle sprain in basketball is the most common injuries due to quick changes in direction with constant jumping and turns. The highest incidence of ankle sprain is 41.1% in basketball followed by other sports.Objectives: To study the effectiveness of 6 weeks core muscle strengthening program in reducing the pain and improving dynamic balance among professional basketball players with ankle sprain.Methodology: An experimental study was conducted among 20 professional basketball players with ankle sprain using Star Excursion Balance Test.20 participants were divided into 2 groups: experimental group (A) and control group (B). During 6-week time, the experimental group performed a core stability program with conventional physiotherapy, whereas the control group was dealt with only the conventional physiotherapy treatment. Result: The result showed that there was significant difference in terms of pain and dynamic balance among the two groups.Conclusion: The study concluded that core muscle strengthening can improve the dynamic balance and reduce the pain in basketball players with ankle sprain.

A multicomponent neuromuscular warm-up program reduces lower-extremity injuries in trained basketball players: A cluster randomized controlled trial

Objective To assess the effects of a novel multicomponent neuromuscular warm-up program on lower-extremity injury incidence in basketball players competing at the regional level. Methods : A cluster randomized controlled experimental design was adopted to compare injury incidence between players exposed to the injury prevention warm-up program and those exposed to a typical warm-up program across an entire basketball season. Four teams consisting of 57 players (male: n = 42; female: n = 15) were allocated to the intervention group (age: 21.6 ± 2.5 years; height: 186.2 ± 8.8 cm; body mass: 80.0 ± 10.4 kg) and four teams consisting of 55 players (male: n = 43; female: n = 12) were allocated to the control group (age: 21.6 ± 2.6 years; height: 186.9 ± 9.1 cm; body mass: 81.5 ± 10.9 kg). The novel warm-up combined running exercises with active stretching, plyometrics, balance, strength, and agility drills. Coaching and medical staff provided details on injury incidence each week. Data analyses included the use of poisson regression analyses and the incidence rate ratio (IRR) with 95% confidence intervals (CI). Results The intervention group experienced a significantly lower ankle sprain incidence rate (IRR = 0.26, 95% CI = 0.05, 0.98, p = 0.02) and a tendency toward a lower knee injury incidence rate (IRR = 0.32, 95% CI = 0.03, 1.78, p = 0.07) compared to the control group. Considering only non-contact lower-extremity injuries of any type, the intervention group experienced a significantly lower incidence rate compared to the control group (IRR = 0.26, 95% CI = 0.05, 0.98, p <0.001). Conclusion This multi-team study demonstrated a novel multicomponent warm-up program resulted in less non-contact lower-extremity injuries, particularly ankle sprains and knee injuries, compared to a typical warm-up program in regional-level male and female basketball players.

Trends in Ankle Sprains Presenting to Emergency Departments During the COVID-19 Pandemic

Category: Trauma; Ankle Introduction/Purpose: It has been suggested that the COVID-19 pandemic has led to patients deferring evaluation and treatment of injuries due to fear of contagion. This, in addition to lockdowns and avoidance of outside activities, may have led to a decrease in the recorded incidence of activity-related injuries. The purpose of this study was to evaluate the effect of the 2020 COVID-19 period on Emergency Department (ED) visits for ankle sprains in the United States, including incidence, demographics, and etiology. Methods: The National Electronic Injury Surveillance System (NEISS) database was queried to identify patients who presented to EDs in the U.S. for ankle sprains between 2001-2020. Population estimates were derived from the U.S. Census Bureau from 2001- 2020 for calculation of incidence in person-years. Chi-square analysis and Wald chi-square tests were performed to assess differences between pre-pandemic (2001-2019) and during-pandemic (2020) periods. Results: Between 2001 and 2020, a total of 315,545 actual ankle sprains were identified in the NEISS database for an estimated 11,904,243 ankle sprains (610,445.2 per year) among a population at risk of 6,185,494,962 person-years. The estimated incidence of ankle sprains in the general population presenting to EDs was 1.92 per 1000 person-years. When analyzing pre- and during- pandemic cohorts, ankle sprain incidence was significantly lower during-pandemic (1.98 vs 0.89 per 1000 person-years; P&lt;0.001). Additionally, patients that visited EDs for ankle sprains during the pandemic were older (30.5% vs 27.0%; P&lt;0.001), more likely to be female (57.8% vs 51.8%; P&lt;0.001), and more likely to be Asian (0.83% vs 0.44%; P=0.047), Native American (0.62% vs 0.18%; P=0.001), or of Pacific Islander race (0.13% vs 0.04%; P=0.008). Ankle sprains were due to sport-related activities in 38% of patients pre-pandemic, as opposed to 29% of patients during-pandemic (P&lt;0.001). Conclusion: The incidence of ankle sprains decreased 65% in 2020, probably owing to activity restrictions during the COVID-19 pandemic. This was further supported by a significant decrease in the proportion of ankle sprains due to sport-related activities. Finally, changes in age, gender, and racial patterns were also identified for this injury type.

Optimisation of the ankle sprain recovery process for junior footballers by computerised dynamometers

Abstract. A sprained ankle is one of the most common joint injuries. This traumatic and painful injury is caused by abnormal stress on the capsular ligament complex and occurs secondary to a movement that forces it to stretch beyond its normal range without losing permanent contact between the joint surfaces. In the United States, the incidence of ankle sprain in the general population (between 2002 and 2006) was 2.15 per 1000 person-years, the highest rates being associated with the age of 10 to 19 years. For people aged 15-24, the incidence was considerably higher in men compared to women, while for those over 30, the incidence was higher in women than men. Epidemiological statistics showed that almost half of all ankle sprains occurred during athletic activities. The motivation for choosing this topic is to highlight the benefits of using the Biodex System 4 Pro in the recovery program for junior footballers with grade II ankle sprains. The assessment made by this device provides information on joint mobility and muscle strength; therefore, the programs used in the recovery process can be performed without putting pressure on the joint and within the range and speed parameters set by the physiotherapist (especially passive, isotonic, isometric and isokinetic ones in the eccentric or concentric mode). The study has shown that Biodex is very helpful in the recovery process because it offers the possibility to work in the isokinetic mode, which reduces the functional recovery period and ensures the return to sport in a minimum time.

Treatment of Chronic Ankle Instability in the Military Population: A Systematic Review.

The high incidence of ankle sprain within the military sets the stage for prevalent chronic ankle instability. The purpose of this review was to compare and evaluate chronic ankle instability treatment strategies in the military population. Electronic databases were systematically searched in accordance with the Preferred Reporting Items for Systematic Reviews guidelines for English-language, human studies with a military patient population that had been diagnosed with and treated for chronic ankle instability. Exclusion criteria were animal, cadaver, and review studies and case reports. Eight studies met the inclusion criteria, representing 695 military service members-625 males (89.9%) and 70 females (10.1%)-and 4 treatment strategies: Broström-related procedures, modified Watson-Jones procedure, Colville's technique, and anatomic lateral ligament reconstruction using semitendinosus tendon allograft. The percentage of satisfactory outcomes was 100% for Colville's technique, and ranged from 73.2% to 94.7% for Broström-related procedures and 72% to 80% for the modified Watson-Jones procedure. Mean American Orthopaedic Foot and Ankle Society scores, anterior drawer displacement, talar tilt, and visual analogue scale scores were also reported. This review demonstrates that the Bröstrom procedure has consistently satisfactory outcomes within the military population, and Colville's technique is another promising option for this patient population but would require additional studies to support this claim. Level IV.

Epidemiology of Ankle Sprain in the Military: A Systematic Review of Literature

Category:Ankle; SportsIntroduction/Purpose:Ankle sprains occur frequently within the general population, however, the extent to which this injury impacts the military population remains unknown. The purpose of this study was to systematically review the literature describing ankle sprains in the military population.Methods:Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, articles were retrieved from PubMed, Embase, and Cochrane Library using the search terms 'military,' 'epidemiology,' 'incidence,' 'prevalence,' 'ankle sprain,' and 'ankle instability.' Inclusion criteria consisted of active military duty status, English language, and levels of evidence I-IV.Results:Nineteen articles were included, representing 1,671,763 study participants from six countries and four branches of the military. Among the ten studies that reported ankle sprain incidence in terms of overall injury incidence, seven studies reported ankle sprain as the most common injury, with an incidence ranging from 2.20% to nearly one third of all injuries in the paratrooper population. Ankle sprain was also reported as the most common injury among lower extremity injuries in two studies, with incidences of 35% and 38.7%, respectively. Ankle sprain incidence rate per 1,000 person-years was reported in four studies, with values ranging from 15.3 to 58.4. Incidence rate was also reported for males and females separately in three of these studies, ranging from 33.89 to 52.7 for males, and 41.17 to 96.4 for females. The number of days lost to ankle sprain ranged from one to eight days per servicemember.Conclusion:Ankle sprains are among the most prevalent injuries within the military population, with a reported incidence that is higher for females than males. This injury results in time away from active duty, which impacts overall readiness within the military system.
