Assessing the COVID-19 pandemic's impact on pediatric baseball and basketball-related craniofacial and neck injuries treated in United States emergency departments, 2003-2022

BACKGROUND

A large proportion of United States (U.S.) youth play basketball, baseball, softball, or T-ball. Each of the activities poses a documented risk of craniofacial and neck injuries. However, few studies have assessed the national prevalence of pediatric craniofacial and neck injuries in this population, particularly following the COVID-19 pandemic.

METHODS

The National Electronic Injury Surveillance System (NEISS) dataset was used to identify pediatric craniofacial and neck injuries associated with basketball, baseball, softball, or T-ball from 2003-2022 in a cross-sectional study. The annual number of injuries before and after the onset of the COVID-19 pandemic with 95% confidence intervals were calculated. Interrupted time series analysis (ITSA) was used to estimate the pandemic's impact on the monthly number of injuries incurred nationally.

RESULTS

Both overall and stratified by sport involvement, the annual number and rate of injuries identified in NEISS decreased significantly after the COVID-19 pandemic. ITSA demonstrated that the monthly number of injuries decreased -4094.4 (95% CI = -5100, -3088.7) immediately after the beginning of the pandemic. The number of injuries began increasing towards pre-pandemic levels at a rate of 110.6 (95% CI = 64, 157.2) injuries per month after the initial plunge.

CONCLUSION

Prior to the-pandemic, there was a steady decline in craniofacial and neck injuries due to basketball, baseball, softball and T-ball among children, aged <18 years. The shutdown during the initial months of the COVID-19 pandemic resulted in a precipitous drop in such injuries. Current rates are approaching pre-pandemic levels and may exceed them. Continued efforts are needed to keep the pre-pandemic progress.

Facial injuries in the National Basketball Association: 2013-14 through 2017-18

OBJECTIVE

To describe the epidemiology, mechanisms, treatment, and disability for facial injuries in National Basketball Association (NBA) athletes.

METHODS

This was a retrospective descriptive epidemiological chart review using NBA Electronic Medical Record (EMR) system. Responses to injuries reported in games, practices, and other activities were used for all data analysis, except for game incidence rates. Incidence rates were calculated by the game-related facial injury incidence per total athlete exposure (player-games).

RESULTS

There were 440 facial injuries among 263 athletes during the 5 NBA seasons with an overall single-season risk of 12.6% and a game incidence of 2.4 per 1000 athlete-exposures (95% CI: 2.18-2.68). The majority of injuries were lacerations (n = 159, 36.1%), contusions (n = 99, 22.5%), or fractures (n = 67, 15.2%), with ocular (n = 163, 37.0%) being the most commonly injured location. Sixty (13.6%) injuries resulted in at least one NBA game missed (224 cumulative player-games) with ocular injuries resulting in the most cumulative games missed (n = 167, 74.6%). Nasal fractures (n = 39, 58.2%) were the most common fracture location followed by ocular fractures (n = 12, 17.9%) but were less likely to lead to games missed (median = 1, IRQ: 1-3) than ocular (median = 7, IQR: 2-10) fractures.

CONCLUSIONS

An average of one in eight NBA players sustained a facial injury each season with ocular injuries being the most common location. While most facial injuries are minor, serious injuries, especially ocular fractures, can result in games missed.

Mechanisms of dental injuries in basketball, United States, 2003-2022

BACKGROUND/AIM

Oral injuries such as oral soft tissue lacerations and contusions can occur in basketball by mechanisms such as running into other players or falling. Given a high enough impact force, dental injuries such as tooth fractures and avulsions can occur. Previous research has studied the different types of oral injuries as well as the mechanisms that cause them. Yet, the mechanisms resulting in dental injuries have remained unexplored. The aims of this study were to investigate the distribution of different oral injuries within each injury mechanism and evaluate which mechanisms were most likely to lead to a dental injury.

MATERIALS AND METHODS

This is a retrospective cohort study using the National Electronic Injury Surveillance System (NEISS). Subjects who experienced oral injuries from basketball between January 1, 2003 and December 31, 2022 were included in this study. The independent variable was the injury mechanism. The dependent variable was the dental injury outcome (yes/no). Multivariate logistic regression was used to measure the association between the injury mechanism and the dental injury outcome. A p < .05 was considered statistically significant.

RESULTS

This study included 4419 subjects who experienced oral injuries (national estimate, 138,980). Approximately 14.7% of oral injuries were dental injuries. Subjects experiencing collisions with objects such as walls or the basketball hoop (odds ratio (OR), 4.39; p < .001), falls (OR, 3.35; p < .001), or contact with the basketball (OR, 1.77; p = .006) had significantly higher odds of sustaining a dental injury relative to those experiencing contact with another player.

CONCLUSIONS

Basketball players experiencing contact to the mouth have high odds of sustaining a dental injury. An understanding of injury mechanisms is important for medical teams to manage these injuries and for coaches to educate athletes on safe and proper playing styles. Furthermore, healthcare providers and basketball staff should encourage athletes to wear mouthguards to reduce the risk of traumatic dental injuries.

Coach perspectives on factors that influence the implementation of injury prevention programs in community netball: A qualitative study

OBJECTIVE

The Netball KNEE Program is an injury prevention program (IPP) developed by Netball Australia. It is promoted to coaches, but implementation is limited. This study explored community netball coaches' perspectives on factors that influence IPP implementation, and ideas on how it could be improved.

METHODS

Twenty-four coaches from 16 netball clubs participated in semi-structured interviews that asked about their beliefs about injury prevention, use of and confidence in delivering IPP, barriers and facilitators to implementation, and suggestions to ease IPP implementation. Interviews were analysed using inductive thematic analysis.

RESULTS

Two themes were identified - Factors that influence IPP implementation (4 sub-themes), and Suggestions to improve IPP implementation (2 sub-themes). Coaches thought early development of injury prevention habits was important. Life roles, coaching experience and engagement with development courses influenced IPP delivery. Coaches expressed concerns about Netball KNEE program length and complexity and lack of implementation support. They suggested the need for a short simple IPP and engagement with health/exercise professionals for implementation.

CONCLUSIONS

This study engaged with stakeholders to identify barriers that need to be addressed to improve IPP implementation in netball. Coaches desired a short simple standardised IPP, and training from physiotherapists or exercise professionals on implementation.

Epidemiologic Trends in Ophthalmic Trauma Related to Major Sports: An NEISS Study

PURPOSE

To examine trends in ophthalmic trauma secondary to five major sports (baseball, soccer, tennis, football, basketball) and identify differences between patient characteristics and time period (pre-COVID vs COVID) of injury.

METHODS

The National Electronic Injury Surveillance System was queried to extract cases related to the sports of interest from 2011-2020. Entries were analyzed by age, sex, diagnosis, location, and disposition, with narrative descriptions assessed to characterize the mechanism of injury and visual sequelae. National incidence was extrapolated and Pearson's ?2 and Fisher's exact tests were performed.

RESULTS

Among 98,995 presentations, most involved male (83.5%) and pediatric patients (59.2%). Contusion/abrasion (57.3%) was the predominant diagnosis, with injuries primarily precipitated by contact with a ball (44.9%) and occurring in the recreational setting (49.0%). Visual sequelae were documented in 6.4% of injuries. Patients were commonly treated/examined and released (95.6%). Between sports, significant differences in diagnosis (p < .001), mechanism of injury (p < .001), location (p < .001), visual sequelae (p < .001), and disposition (p = .005) were observed. Stratification by age indicated significant differences in diagnosis, mechanism of injury, and location (all p < .001). Stratification by sex indicated significant differences in the mechanism of injury (p < .001) and visual sequelae (p = .04). Stratification by time period indicated significant differences in diagnosis (p = .002) and mechanism of injury (p = .001).

CONCLUSION

There are notable differences in sports-related ocular injuries by patient characteristic, revealing important considerations for their clinical evaluation and the development of safety guidelines.

Establishing Phase Definitions for Jump and Drop Landings and an Exploratory Assessment of Performance-Related Metrics to Monitor During Testing

ABSTRACT

Harry, JR, Simms, A, and Hite, M. Establishing phase definitions for jump and drop landings and an exploratory assessment of performance-related metrics to monitor during testing. J Strength Cond Res 38(2): e62-e71, 2024-Landing is a common task performed in research, physical training, and competitive sporting scenarios. However, few have attempted to explore landing mechanics beyond its hypothesized link to injury potential, which ignores the key performance qualities that contribute to performance, or how quickly a landing can be completed. This is because a lack of (a) established landing phases from which important performance and injury risk metrics can be extracted and (b) metrics known to have a correlation with performance. As such, this article had 2 purposes. The first purpose was to use force platform data to identify easily extractable and understandable landing phases that contain metrics linked to both task performance and overuse injury potential. The second purpose was to explore performance-related metrics to monitor during testing. Both purposes were pursued using force platform data for the landing portion of 270 jump-landing trials performed by a sample of 14 NCAA Division 1 men's basketball players (1.98 ± 0.07 m; 94.73 ± 8.01 kg). The proposed phases can separate both jump-landing and drop-landing tasks into loading, attenuation, and control phases that consider the way vertical ground reaction force (GRF) is purposefully manipulated by the athlete, which current phase definitions fail to consider. For the second purpose, Pearson's correlation coefficients, the corresponding statistical probabilities ( α = 0.05), and a standardized strength interpretation scale for correlation coefficients (0 < trivial ≤ 0.1 < small ≤ 0.3 < moderate ≤ 0.5 < large ≤ 0.7 < very large) were used for both the group average (i.e., all individual averages pooled together) and individual data (i.e., each individual's trials pooled together). Results revealed that landing time, attenuation phase time, average vertical GRF during landing, average vertical GRF during the attenuation phase, average vertical GRF during the control phase, vertical GRF attenuation rate, and the amortization GRF (i.e., GRF at zero velocity) significantly correlated with landing performance, defined as the ratio of landing height and landing time ( R ≥ ± 0.58; p < 0.05), such that favorable changes in those metrics were associated with better performance. This work provides practitioners with 2 abilities. First, practitioners currently assess jump capacity using jump-landing tests (e.g., countermovement jump) with an analysis strategy that makes use of landing data. Second, this work provides preliminary data to guide others when initially exploring landing test results before identifying metrics chosen for their own analysis.

Effectiveness of a specific strength program of the gluteus maximus muscle to improve dynamic postural control in female basketball players. A randomized controlled trial

BACKGROUND

Basketball is a team sport in which players perform multidirectional movements, jumps and landings, experiencing abrupt accelerations and decelerations and numerous changes of rhythm. In this sport, speed and intensity are two key factors that are associated with an increased risk of injury. The aim of this randomized controlled trial was to determine the effectiveness of a specific gluteus maximus strength programme as preventive work for young female basketball players, to improve dynamic postural stability and to observe its impact in the rate of lower limb injuries, vertical jump, dynamic knee valgus and pain.

RESEARCH QUESTION

Is effective a strength programme to improve dynamic postural stability, vertical jump and dynamic valgus in female basketball players?

METHODS

A hundred and thirteen female basketball players that play in professional clubs were recruited, reaching the final stage 92 (46 per group). One group (CG) received conventional injury prevention training while the experimental group (EG) added to the conventional team prevention program, a gluteus maximus strength programme of 5 months composed of 4 exercises/2 days per week/2 sets of 10 repetitions per leg.

RESULTS

The total injury incidence decreased from 0.33 to 0.16 cases (control group pre=0.43 to post=0.14 cases, EG pre=022 to post=0.19). The EG improved overall (p = 0.000), posterior (p = 0.001), posteromedial (p = 0.001) and posterolateral (p = 0.000) dynamic stability of the right leg; anterior (p = 0.024), medial (p = 0.07) and posteromedial (p = 0.01) of the left leg. Both groups improved vertical jump (GC: p = 0.045 and GE: p = 0.000). There was no significant improvement in pain or valgus.

SIGNIFICANCE

This strength programme is effective in improving dynamic stability especially of the dominant leg and jump height.

Management of Patellar Tendinopathy

Patellar tendinopathy is a common pathology typically seen in athletes involved in repetitive explosive jumping and running activities. Also known as jumpers' knee, it is commonly seen in high-level basketball players. Typically, athletes continue to play with symptoms, which can be aggravated and progress to partial patellar tendon tears. When partial patellar tendon tears occur, prolonged recovery and decreased performance is commonly seen. The pathology and treatment can be frustrating for both the athlete and medical provider. Patellar tendinopathy typically does not involve inflammation but rather microinjury to the tendon fibers, which leads to mucoid degeneration, necrosis, and loss of transitional fibrocartilage. When partial tendon tears do occur, the typical location is posteromedially adjacent to the patella. Treatment involves a stepwise approach starting with nonoperative means, including activity modification, nonsteroidal anti-inflammatories, and physical therapy focused on eccentrics. Extracorporeal shock wave treatments and injections with platelet-rich plasma or bone marrow aspirate concentrate should be considered, with evolving literature to support their use. Ultrasound percutaneous tendon scrapping with a needle supplemented with the aforementioned injections is an emerging treatment option that the authors have found to be helpful, although further studies are required. Surgical intervention is considered after failure of nonoperative treatments, and typically occurs in tears greater than 50% of the tendon thickness and in tendons with increased thickness (>8.8 mm). Open or arthroscopic debridement can be considered, with no studies showing superior outcomes with either technique; however, no high-quality comparison studies exist. The authors prefer an open technique where, much like a bone-patellar tendon-bone harvest, the unhealthy proximal tendon and bone are excised with then closure of the healthy tendon with absorbable sutures. Suture anchor repair may also be used when necessary. In a recent systematic review, surgical management of patellar tendinopathy has been shown to result in improved patient-reported outcomes with return to sport at high levels.1 Treatment for the difficult and sometimes frustrating pathology of patellar tendinopathy continues to evolve, with biologic and less-invasive ultrasound-based treatments showing promise, and surgical intervention providing reliable outcomes.

Facial Injuries in the National Basketball Association

BACKGROUND

Sport injuries can negatively impact physical and psychological aspects of athletes. There is a gap in the literature regarding facial trauma present in basketball.

PURPOSE

The purpose of this study is to identify and describe facial trauma present in the National Basketball Association (NBA).

STUDY DESIGN, SETTING, SAMPLE

This is a retrospective cohort study in which the sample (n = 206) consists of players that missed games due to facial injuries in the NBA, the data were collected from a public access online resource.

INDEPENDENT VARIABLE

The predictor variables were player position (center, point guard, shooting guard, small forward, and power forward), team conference (Eastern/Western), and if played games occurred in playoff season.

MAIN OUTCOME VARIABLES

The primary outcome variable was the injury location (upper, middle, and lower facial third), and the secondary outcome was type of injury (soft tissue/bone fracture).

COVARIATES

Player's age, height, weight, and body mass index were collected.

ANALYSES

χ2 and logistic regression were calculated to determine associations between predictor and outcome variables. Logistic regression was used to determine if variables were predictive for injury. Odds ratio was also computed for significant results. P value less than .05 (95% confidence interval) was considered statistically significant.

RESULTS

A total of 206 players missed games due to facial injuries, and a total of 212 injuries were quantified. The mean age of the injured players was 27.24 ± 4.06 years, mean height (centimeters) was 201 ± 59.31 cm, mean weight (kilograms) was 99.48 ± 12.41 kg, and body mass index was 24.52 ± 1.75 kg/m2. Of the 212 injuries, none of them occurred in the upper facial third, 158 (75%) were in the middle third, and 54 (25%) were in the lower third; 151 of them were fractures (61%) and 61 were soft tissue injuries (29%). Most injuries were concentrated in centers (23%) and power forwards (23%). The most common fracture occurred in the nasal bones (39.2%), and most soft tissue injuries occurred in the eye globes (25%). Almost all injuries occurred during regular season games (97%), and the Eastern conference was slightly predominant (52%).

CONCLUSION AND RELEVANCE

Significant facial trauma in the NBA has risen in recent years. The player's position, height, and weight were the primary factors associated with facial trauma in the NBA.

The use of mouthguards and related factors among basketball players in Indonesia

BACKGROUND

Basketball is a sport with a higher injury rate. Regardless, few basketball players use mouthguards, which predisposes them to injuries. The use of mouthguards (UoM) could be related to several factors. This study aims to identify factors associated with UoM and to construct a model from the factors among basketball players in Indonesia.

METHODS

Through convenience sampling, a total of 286 among basketball players in Indonesia was included in this cross-sectional study. These participants filled out online a modified questionnaires regarding demographic and several factors related to UoM. The data was analyzed using chi-square test, independent-sample t-test, binary logistic regression, and structural equation modeling (SEM).

RESULTS

There were 286 players. 127 of them were males and 159 were females. Of them, 86 (30.1%) used mouthguards. Age, duration (in year), and weekly practicing basketball (in hour) were all significantly different between mouthguards users and non-users with (p = 0.005, p = 0.036 and p = 0.035), respectively. The UoM was significantly associated with level of awareness, injury experience, social support, and oral health professional (OHP) support with (p = 0.002, p < 0.001, p < 0.001 and p < 0.001), respectively. This result was also supported by a variety of variables' ORs, which range from 1.28 to 5.97. The coefficient of determination (R2) was 0.27.

CONCLUSIONS

The UoM among basketball players in Indonesia was related to several factors, including the level of knowledge, level of awareness, duration of basketball career, injury experiences, social support, and oral health professionals' support which was constructed to propose a model. The model could explain 27% of the relationship between variables and UoM among Indonesian basketball players. This model will be useful for more comprehensive initiatives to promote oral health. It might be applicable for other countries as well as other sports communities / physical activities.

Biomechanics and situational patterns associated with anterior cruciate ligament injuries in the National Basketball Association (NBA)

OBJECTIVES

Perform a comprehensive video analysis of all anterior cruciate ligament (ACL) injuries in National Basketball Association (NBA) athletes from 2006 to 2022 to determine the associated biomechanics, injury mechanism and game situation.

METHODS

NBA players diagnosed with an ACL tear from 2006 to 2022 were identified and videos of each injury evaluated by two reviewers. Visual evaluation included assessment of joint kinematics at three time points: initial contact of the injured leg with the ground (IC), 33 milliseconds later (IC+33) and 66 milliseconds later (IC+66). Game situation was assessed qualitatively.

RESULTS

Videos of 38 out of 47 (80.9%) ACL tears were obtained. 9 injuries were non-contact, while 29 involved indirect contact. Between IC and IC+33, average knee valgus increased from 5.1° to 12.0° and knee flexion increased from 12.6° to 32.6°. At all time points, the majority of injuries involved trunk tilt and rotation towards the injured leg, hip abduction and neutral foot rotation. The most common game situations for injury included the first step when attacking the basket following picking up the ball (n=13), landing following contact in the air (n=11) and jump stop (n=5).

CONCLUSION

Three major mechanisms predominate ACL tears in NBA players: the first step following picking up the ball when attacking, landing and jump stops. None of the injuries reviewed demonstrated direct contact to the knee, emphasising the importance of body kinematics in this injury pattern. The increase in knee valgus and knee flexion between IC and IC+33 should be noted as a possible precipitant to injury.

Characteristics of Sports-Related Injuries Presenting to a Pediatric Emergency Department

OBJECTIVE

Pediatric injuries associated with participation in sports are common. Understanding the epidemiology and trends of sports-related injuries is an important component of injury prevention efforts and is the objective of this study.

METHODS

A retrospective review of sports injuries presenting during the course of 1 year (2019) to the emergency department (ED) of Benjamin Russell Hospital for Children, a large academic children's hospital, was performed. Inclusion criteria focused on patients 18 years old and younger whose ED visit resulted from active participation in a sport. Cases were identified using International Classification of Diseases, Tenth Revision codes. Demographic data were collected and included sex, age, race, injury specifics (sport, location, type, and mechanism). Descriptive statistics were performed and categorical variables were analyzed using the χ2 test.

RESULTS

A total of 1333 injuries seen by the ED during 2019 were sports injuries. Most commonly, these injuries were associated with football (43%), basketball (36%), soccer (11%), or baseball (8%). Considering sports-related injuries, 428 (32%) patients were 12 years and younger and 905 (68%) were 12 years old and older. The median age was 13 years (interquartile range 4 years). Other demographic findings included male sex 1143/1333 (86%) and Black race 835/1333 (63%). School was the most common location for sports injuries (28%). When comparing injuries by age groups (younger than 12 vs 12 and older), football and baseball injuries were more common in those younger than 12 years (53% vs 38%, z = 5.2, P < 0.00001; and 14.0% vs. 5.6%, z = 4.9, P < 0.00001, respectively), whereas basketball and soccer injuries were more common in those 12 years and older (43% vs 22%, z = 7.4, P < 0.00001; and 11.4% vs 9.3%, z = 5.9, P < 0.00001, respectively). When comparing injuries by sex, football and baseball injuries were more common in males (49% vs 6%, z = 11.1, P < 0.00001; and 9.4% vs. 2.1%, z = 3.3, P < 0.00001, respectively), whereas basketball and soccer injuries were more common in females (59% vs 32%, z = 7.2, P < 0.00001; and 27% vs 8%, z = 7.8, P < 0.00001, respectively.

CONCLUSIONS

Sports injuries that are commonly encountered in the ED differ in age and sex. Basketball and soccer injuries were more likely to be encountered in older females, whereas baseball and football injuries were more likely seen in younger males. This may reflect efforts that have been previously focused on the sports considered to be higher risk, especially for concussive injuries. This information can help guide future preventive efforts provided by primary physicians, schools, and coaches.

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 lower-extremity injuries, particularly ankle sprains and knee injuries, compared to a typical warm-up program in regional-level male and female basketball players.

THE INCIDENCE OF SPORTS INJURIES AMONG SCHOOL-AGED CHILDREN AND ADOLESCENTS

It is estimated that approximately one in ten school-aged children experience sports-related injuries annually. These injuries are most common at 12 years of age. Boys are more likely to get injured and more likely to get seriously injured than girls. The probability of injury is greater in contact or high-impact sports, with American soccer accounting for the largest number of injuries, followed by wrestling, basketball, soccer, and baseball. In certain sports, such as horseback riding, women are four times more likely to sustain injuries. The presented literature review details the incidence of various sports-related injuries in adolescents. Sports-related injuries observed in children under the age of 10 are nonspecific and include contusions, mild sprains, and fractures of the extremities, most commonly Salter-Harris fractures (growth plate fractures) or plastic fractures. In young athletes, sports-related injuries of the ligaments or muscles, as well as spinal or head injuries, are rare. This is particularly true during puberty, where growth plate fractures and musculoskeletal injuries occur more frequently.

CNN sensor based motion capture system application in basketball training and injury prevention

Basketball is a high-intensity sport, and sports injuries often occur. Therefore, how to monitor the sports status of basketball players in real time, discover and prevent the occurrence of sports injuries in time, has become an urgent problem for athletes and coaches. In this paper, a motion capture system based on CNN sensor is proposed. Through the application of sensor, real-time monitoring of athletes' motion state, the system can collect athletes' movement track, speed, acceleration, stride frequency, heart rate, energy consumption and other parameters in real time. By analyzing the movement data, it can timely warn and deal with the occurrence of sports injuries. In this paper, convolutional neural network (CNN) is used to process and analyze motion data, so that the motion capture system has higher precision and accuracy. Through the training and optimization of CNN, the system can identify and analyze motion data more accurately, and improve the performance and effect of the motion capture system. The motion capture system based on CNN sensor can realize real-time monitoring and prevention of sports injuries for basketball players, provide more comprehensive, scientific and real-time sports data for athletes and coaches, help them better conduct training and adjust tactics, and improve the competitive level and safety of basketball games.

Shoulder pain in wheelchair basketball athletes: A scoping review

CONTEXT

Wheelchair basketball athletes have increased upper limb stress, which frequently leads to shoulder pain.

OBJECTIVE

The purpose of this scoping review was to summarize the existing literature on shoulder pain in wheelchair basketball athletes.

METHODS

We searched PubMed, Cochrane Library, Scopus, and PEDro databases for studies performed between January 1990 and February 2021. Two independent reviewers screened the studies according to the inclusion and exclusion criteria. Participants' characteristics and results were extracted from the study.

RESULTS

The initial database search yielded 2455 articles, 11 of which met the inclusion criteria. This review included seven studies in its final analysis; among them, seven determined the prevalence and incidence of shoulder pain, five investigated the factors and mechanisms contributing to shoulder pain, and two reported the treatment and preventive measures. The prevalence of shoulder pain in wheelchair basketball players ranged from 38%-75%, and the incidence of shoulder pain was 14%. Factors/mechanisms included overuse, decreased trunk control, and driving posture. Treatment/preventive measures consisted of shoulder and scapular muscle strengthening and stretching exercises. However, the literature on treatment/prevention was scarce, and its effectiveness was unclear.

CONCLUSION

This scoping review confirmed the high prevalence of shoulder pain in wheelchair basketball players; despite this, studies regarding treatment or preventive measures remain lacking. Further studies investigating the mechanism of onset of shoulder pain and the effectiveness of therapeutic and preventive measures are needed in the future.

Progressing On-Court Rehabilitation After Injury: The Control-Chaos Continuum Adapted to Basketball

BACKGROUND: Sport-specific training is an integral component of returning to sport following injury. Frameworks designed to guide sport-specific rehabilitation need to integrate and adapt to the specific context of elite sport. The control-chaos continuum (CCC) is a flexible framework originally designed for on-pitch rehabilitation in elite football (soccer). The concepts underpinning the CCC transfer to other elite sport rehabilitation environments. CLINICAL QUESTION: How can practitioners and clinicians transfer the CCC to elite basketball, to support planning and return to sport? On-court rehabilitation is a critical sport-specific rehabilitation component of return to sport, yet there are no frameworks to guide practitioners when planning and delivering on-court rehabilitation. KEY RESULTS: Based on our experience working in the National Basketball Association, we report how the CCC framework can apply to elite basketball. We focus on the design and delivery of progressive training in the presence of injury in this basketball-specific edition of the CCC. Given the challenges when quantifying "load" in basketball, we encourage practitioners and clinicians to consider the qualitative aspects of performance such as skill, sport-specific movement, contact, and decision making. CLINICAL APPLICATION: The 5-phase framework describes training progression from high control, a return to on-court running, to high chaos, a return to "live" unrestricted basketball. The model can be adapted to both short- and long-term injuries based on injury and progression criteria. Strength and power "diagnostics" can be strategically implemented to enhance decision making throughout the return to sport continuum. J Orthop Sports Phys Ther 2023;53(9):1-12.

Is ankle taping effective to limit the ankle dorsiflexion in a single-training session? An observational study in semi-professional basketball players

BACKGROUND

Ankle taping (AT) is effective in preventing ankle sprain injuries in most common sports and is employed in rehabilitation and prevention sports.

OBJECTIVE

This study aimed to investigate the effectiveness of AT to restricting excessive frontal plane ankle movements in semi-professional basketball players throughout the training session.

DESIGN AND SETTING

A cross-sectional study was performed at the Universidad Europea de Madrid.

METHODS

Forty male and female semi-professional basketball players were divided into two groups. The ankle dorsiflexion range of motion (ROM) and interlimb asymmetries in a weight-bearing lunge position were evaluated at four time points: 1) with no tape, 2) before practice, at 30 min of practice, and 3) immediately after practice.

RESULTS

In male basketball players, no differences were observed in the right and left ankles between the baseline and 30 min and between baseline and 90 min of assessment. In female athletes, significant differences were reported between baseline and pre-training assessments for the right ankle and also significant differences between baseline and 90 min in both ankles.

CONCLUSIONS

Ankle taping effectively decreased the ankle dorsiflexion ROM in male and female basketball players immediately after application. However, ROM restriction was very low after 30 and 90 min, as assessed in a single basketball practice. Therefore, the classic taping method should be revised to develop new prophylactic approaches, such as the implementation of semi-rigid bracing techniques or the addition of active stripes during training or game pauses.

Epidemiology of injuries during Iran wheelchair basketball professional league: predictive risk factors and prevention strategies

BACKGROUND

Very few studies have investigated athletes with disabilities during a long period of competitions, such as a professional league. Also, there are limited findings related to specific mechanisms and risk factors of injury, and prevention strategies in Wheelchair Basketball. Therefore, the objective of this study was to investigate the rate and characteristics of injuries in the 2021-2022 Iran Wheelchair Basketball League and present prevention strategies.

METHODS

This retrospective study was conducted after the 2021-2022 (Mar 2021-Sep 2022) competition season. The sample size consists of 36 players, who were randomly selected among 129 players. All the data was processed using SPSS (version 21).

RESULTS

111 injuries were registered, equivalent to 132 per 100 players (95% CI: 100-180) and 8.16 Injuries per 1000 hours of athlete exposure (6.2-9.8). Also, 77.8% occurred during training and 22.2% in competitions. Most injuries affected the fingers and hands (35.13%), and shoulders (22.57%). The most common types of injuries were contusions (30.63%), laceration and skin lesion (23.42%), and muscle spasms (13.51%), in which, half of the injuries were slight (0-1 days), 27.8% (mild 4-7 days), and 22.2% moderate (8-28 days). Also, 66.9% of injuries were new, and 33.1% were recurrent. Most situations and actions leading to injury include quick wheelchair pushing (29.72%), the intense ball hitting (17.14%), and sudden stops or changes of direction of the wheelchair (12.63%). A multiple linear regression analysis (Enter method) demonstrated (R2 Adjusted=0.530) Wheelchair inappropriateness (P=0.015), lack of protective equipment (P=0.028), and previous injury (P=0.003) explained close to 55% of the injury rate.

CONCLUSIONS

The injury rate during the league period was higher than the amounts reported from Paralympic games. Prevention strategies should be focused on rethinking athletes' pre-season readiness evaluation, return to play assessments and protection equipment technologies.

Demographic Factors and Instantaneous Lower Extremity Injury Occurrence in a National Collegiate Athletic Association Division I Population

CONTEXT

Temporal prediction of the lower extremity (LE) injury risk will benefit clinicians by allowing them to better leverage limited resources and target those athletes most at risk.

OBJECTIVE

To characterize the instantaneous risk of LE injury by demographic factors of sex, sport, body mass index (BMI), and injury history.

DESIGN

Descriptive epidemiologic study.

SETTING

National Collegiate Athletic Association Division I athletic program.

PATIENTS OR OTHER PARTICIPANTS

A total of 278 National Collegiate Athletic Association Division I varsity student-athletes (119 males, 159 females; age = 19.07 ± 1.21 years, height = 175.48 ± 11.06 cm, mass = 72.24 ± 12.87 kg).

MAIN OUTCOME MEASURE(S)

Injuries to the LE were tracked for 237 ± 235 consecutive days. Sex-stratified univariate Cox regression models were used to investigate the association between time to first LE injury and sport, BMI, and LE injury history. The instantaneous LE injury risk was defined as the injury risk at any given point in time after the baseline measurement. Relative risk ratios and Kaplan-Meier curves were generated. Variables identified in the univariate analysis were included in a multivariate Cox regression model.

RESULTS

Female athletes displayed similar instantaneous LE injury risk to male athletes (hazard ratio [HR] = 1.29; 95% CI= 0.91, 1.83; P = .16). Overweight athletes (BMI >25 kg/m2) had similar instantaneous LE injury risk compared with athletes with a BMI of <25 kg/m2 (HR = 1.23; 95% CI = 0.84, 1.82; P = .29). Athletes with previous LE injuries were not more likely to sustain subsequent LE injury than athletes with no previous injury (HR = 1.09; 95% CI = 0.76, 1.54; P = .64). Basketball (HR = 3.12; 95% CI = 1.51, 6.44; P = .002) and soccer (HR = 2.78; 95% CI = 1.46, 5.31; P = .002) athletes had a higher risk of LE injury than cross-country athletes. In the multivariate model, instantaneous LE injury risk was greater in female than in male athletes (HR = 1.55; 95% CI = 1.00, 2.39; P = .05), and it was greater in male athletes with a BMI of >25 kg/m2 than that in all other athletes (HR = 0.44; 95% CI = 0.19, 1.00; P = .05), but these findings were not significantly different.

CONCLUSIONS

In a collegiate athlete population, previous LE injury was not a contributor to the risk of future LE injury, whereas being female or being male with a BMI of >25 kg/m2 resulted in an increased risk of LE injury. Clinicians can use these data to extrapolate the LE injury risk occurrence to specific populations.

The Epidemiology of Pediatric Basketball Injuries Presenting to US Emergency Departments: 2011-2020

OBJECTIVES

The purpose of this study is to describe the national epidemiology of basketball-related injuries in children and adolescents presenting to US emergency departments (EDs) from 2011 to 2020 and to quantify the effect of the COVID-19 pandemic.

METHODS

The National Electronic Injury Surveillance System database was queried for cases of injury in persons aged 0 to 19 years related to product code 1205 (basketball and related equipment) presenting from January 1, 2011 to December 31, 2020. National injury estimates were calculated using National Electronic Injury Surveillance System-recommended weights and strata. The US Census data were used to determine the incidence of injury by age group and by sex. To quantify the effect of COVID-19, an interrupted time series analysis was performed using March 1, 2020 as the interrupting time point. The pre-COVID-19 trend was used to estimate the difference in injuries attributable to the COVID-19 pandemic.

RESULTS

From 2011 to 2020, an estimated 3,210,953 (95% confidence interval = 2,655,812-3,788,094) visits were made to US EDs for basketball-related injuries in those aged younger than 20 years, corresponding to a mean annual incidence of 391 injuries per 100,000 population. The mean age of injury was 14.4 years (95% confidence interval = 14.3-14.5). Boys were more often injured than girls (76% vs 24% of all injuries, respectively). The foot was the most injured body part, accounting for 24% of injuries. Strains or sprains were the most common injury type (38% of injuries). During the COVID-19 pandemic, there were 155,638 fewer injuries than were expected based on pre-COVID-19 trends. During COVID-19, there were no significant differences in the proportions of injury types, body parts involved, sex, or age.

CONCLUSIONS

Basketball remains a frequent cause of injury, especially in adolescents. The COVID-19 pandemic profoundly reduced the frequency of basketball-related injuries, but did not affect the type and body location of injuries presenting to the ED.

A cross-sectional retrospective survey of injury situation and prevalence in female recreational netball players with a focus on knee injuries

OBJECTIVES

To examine situations of injury and injury prevalence in female adult recreational netball players with a focus on knee injuries.

DESIGN

Cross sectional retrospective online survey.

PARTICIPANTS

193 female adult recreational netball players.

MAIN OUTCOME MEASURES

Any injury sustained in the previous 12 months, situation of injury, any knee injuries sustained in the previous five years, the length of time unable to play netball, and knee injury management.

RESULTS

In the previous 12 months, 61% of respondents sustained injury to the lower limb, and 27% to the upper limb. Lower limb injury situations were mostly landings (46%). Upper limb injury situations were mostly collisions with an opponent (27%). 46% reported sustaining a knee injury in the previous five years. Following knee injury, players were unable to play netball for 6.8 ± 7.0 months (training); and 8.2 ± 7.4 months (matches) respectively.

CONCLUSIONS

Lower limb injury is more common than upper limb injury in recreational adult female adult netball players. Landing was the most common situation of injury for the lower limb including knee injuries. In the previous five years, nearly half of the players had sustained a knee injury resulting in more than six months out of the game.

Who Does Not Respond to Injury Prevention Warm-up Programs? A Secondary Analysis of Trial Data From Neuromuscular Training Programs in Youth Basketball, Soccer, and Physical Education

OBJECTIVES: To identify factors associated with nonresponse to neuromuscular training (NMT) warm-up programs among youth exposed to NMT warm-ups. METHODS: This is a secondary analysis of youth (aged 11-18 years) in the intervention groups of 4 randomized controlled trials in high school basketball, youth community soccer, and junior high school physical education. Youth who were exposed to NMT and who sustained an injury during the study were considered nonresponders. Odds ratios (ORs) were based on generalized estimating equations logistic regression controlling for clustering by team/class and adjusted for age, weight, height, balance performance, injury history, sex, and sport (soccer/basketball/physical education). RESULTS: A total of 1793 youth were included. Youth with a history of injury in the previous year had higher odds (OR = 1.64; 95% CI: 1.14, 2.37) of injury during the study, and females were more likely (OR = 1.67; 95% CI: 1.21, 2.31) to sustain an injury than males who were participating in NMT. Age was not associated with the odds of sustaining an injury (OR = 1.10; 95% CI: 0.93, 1.30). Soccer players benefited most from greater adherence, with 81% lower odds of injury (OR = 0.19; 95% CI: 0.06, 0.57) when completing 3 NMT sessions a week compared with 1 session per week. CONCLUSION: Factors associated with nonresponse to an NMT warm-up program were female sex, history of injury during the previous 12 months, and lower weekly NMT session adherence in some sports (soccer).

Effect of Rehabilitation Physical Training on Basketball Injury under Ultrasound Examination

In order to solve the problem of observing the effect of rehabilitation physical training on basketball player injury, a kind of observation study on the effect of rehabilitation physical training on basketball player injury based on memory ultrasound examination was proposed. This study makes a comprehensive analysis of physical fitness training factors such as physical fitness test plan, training arrangement, training method, training monitoring, and effect evaluation. Through the experiment, it is found that there are still gaps in physical training, diagnostic standards, training plans and requirements, load monitoring, standardization of operation, nutrition, and recovery in the training organization. There are only 23.81% of full-time physical coaches and 25.40% of professional team doctors at all levels of sports teams. There were only 23.81% of full-time physical fitness coaches and 25.40% of professional team doctors in all levels of sports teams. Basketball players in the basketball injury survey had 67 sports injuries throughout the year, with a rate of 3.35 injuries per person and 2.48 injuries per 1000 hours. The location of chronic injuries is usually the lower back, knee joint, and ankle. The main injuries are due to the physical component, with injuries occurring most frequently throughout the training season in July, August, and September. Experiments show that good and professional physical training can reduce the risk of injury to a greater extent than strengthening the specific skills of athletes.

Sports Medicine Image Modeling for Injury Prevention in Basketball Training

In order to solve the problem of sports medical image in basketball training, a sports medical image modeling research method based on injury prevention in basketball training was proposed. By the method, the current situation of sports injury in university basketball was investigated. At the same time, the injury factors were analyzed on four occasions, including basketball class, extracurricular activities, competition, and training. In order to reduce the occurrence of injury and enhance the security of basketball sports for nonbasketball students of physical education, combined with the problems and reasons, the corresponding suggestions were put forward. Through the experiment, it was found that the incidence of basketball injury for nonbasketball male university students was as high as 90.7%. The results of the experiment showed that it was necessary to enhance the awareness of self-protection, control emotions and exhibitionism, strengthen physical training, attach importance to basic skills training, do warm-up activities, stay focused, pay attention to exercise load, and prevent excessive fatigue.

Injuries in College Basketball Sports Based on Machine Learning from the Perspective of the Integration of Sports and Medicine

Basketball is one of the popular sports in colleges. Basketball injuries are a common thing, and the use of machine learning and other technologies can effectively reduce basketball injuries, which should start with prevention. Nonstandard basketball movements and lack of physical coordination will not only reduce sports efficiency for athletes but also increase the probability of injury. Therefore, effective reduction and targeted prevention of nonstandard actions are of great significance to college basketball. With the development of science and technology, artificial intelligence technology is closer to our lives. Based on the machine learning platform, this paper studies basketball injuries from the perspective of the integration of sports and medicine. Research on what aspects cause college students' basketball injuries is needed for the future. Effectively preventing college students from being injured in basketball is an urgent problem in the field of sports medicine. To find the most suitable machine learning platform for college basketball injury research, this article will introduce three different methods for comparative analysis. The techniques used in the experiment in this paper are traditional BP neural network technology, SCG neural network technology, and RBF neural network technology. Through experiments, it is known that, through experiments, RBF neural network technical prediction accuracy rate is as high as 95.4%, which is a relatively good neural network algorithm for studying the basketball loss of college students.

“In your face”: The transition from physical to symbolic violence among NBA players

The NBA has undergone formative changes since commissioner David Stern began his tenure. Stern has endeavored to make the NBA a consumer-friendly and marketable league by implementing sanctions on physical violence. This study takes a closer look at Stern’s efforts by examining the interplay between two forms of violence in NBA basketball players on the court: “old fashioned” physical violence (PV) and symbolic violence (SV). Of the 117 NBA finals broadcast for twenty years from 1998 to 2018, a stratified random sample (36 games or 30.8%) of the violations and commentators’ comments were coded, providing a wide perspective on forms of violence over time. The findings reveal that although the number of PV incidents decreased, SV increased starting in 2014, to the extent that SV incidents were more frequent than PV. A thematic analysis of the commentators’ remarks associated with these incidents showed that they support and encourage PV, whereas SV tends to be perceived as harmless and therefore permissible to ignore. Unlike PV, SV is not perceived to be as worthy of media coverage. The relative lack of commentator interest is indicative of the lack of “glamour” of SV in the NBA league. It is suggested that since viewers of professional sports often emulate the players, the increase of SV within the NBA is likely to be mirrored in fans in their everyday lives and in amateur basketball players. Although the rise in SV causes fewer physical injuries in professional basketball players, it nevertheless can cause psychological harm.

Basketball vs. Hockey-The Changing Face of Sport-Related Injuries in Canada

OBJECTIVE

To characterize and compare the incidence of basketball-related, soccer-related, and hockey-related injuries over a 10-year period.

DESIGN

Cohort analysis of sport-related injuries using multiple Ontario healthcare databases.

SETTING

Emergency department visits in Ontario, Canada.

PATIENTS

Any patient who sustained musculoskeletal injuries sustained while playing basketball, soccer, or hockey between 2006 and 2017 were identified.

ASSESSMENT OF RISK FACTORS

Sport of injury, age, sex, rurality index, marginalization status, and comorbidity score.

MAIN OUTCOME MEASURES

Annual Incidence Density Rates of injury were calculated for each sport, and significance of trends was analyzed by assessing overlap of 95% confidence intervals.

RESULTS

One lakhs eighty five thousand eighty hundred sixty-eight patients (median age: 16 years, interquartile range 13-26) received treatment for sport-related injuries (basketball = 55 468; soccer = 67 021; and hockey = 63 379). The incidence of basketball-related and soccer-related injuries increased from 3.4 (3.3-3.5) to 5.6 (5.5-5.7) and 4.4 (4.3-4.5) to 4.9 (4.8-5) per 10 000 person years, respectively, whereas the incidence of hockey-related injuries decreased from 4.7 (4.6-4.8) to 3.7 (3.6-3.8). Patients with basketball injuries were more marginalized (3.01 ± 0.74) compared with patients with soccer and hockey injuries (2.90 ± 0.75 and 2.72 ± 0.69, respectively).

CONCLUSIONS

Accurate regional epidemiologic information regarding sports injuries can be used to guide policy development for municipal planning and sport program development. The trends and demographic patterns described highlight general and sport-specific injury patterns in Ontario. Populations with the highest incidence of injury, most notably adolescents and men older than 50, may represent an appropriate population for injury risk prevention.

Hallux Sesamoid Injury Characteristics in Young Athletes Presented to the Sports Medicine Clinic

OBJECTIVE

To investigate clinical diagnoses, sports participation, and return to sport timeline associated with hallux sesamoid injuries with sex comparisons.

DESIGN

Descriptive epidemiology study.

SETTING

Sports medicine clinics at a tertiary-level pediatric medical center.

PATIENTS

Six hundred eighty-three young athletes (546 women and 137 men).

INDEPENDENT VARIABLES

Sex (women vs men).

MAIN OUTCOME MEASURES

Clinical diagnoses, participating sports, and injury timeline.

RESULTS

The most common diagnosis was sesamoiditis (62.6%). The top 3 primary sports were dance (34.6%), running (13.7%), and soccer (11.7%). When stratified by sex, dance (40.1%), running (13.6%), and soccer (10.7%) were the top primary sports for women while running (19.4%), soccer (18.5%), and basketball (11.3%) were the leading diagnoses for male athletes. The mean time between injury occurrence and first clinic visit was 135.5 ± 229.3 days. The mean time between the first clinic visit and return to sport was 104.3 ± 128.2 days. Comparison by sex showed that women had a longer mean time than men (women: 111.5 ± 132.5 days, men: 67.2 ± 96.3 days, P = 0.001). The mean time from injury occurrence to return to sport was 235.2 ± 281.0 days. Women showed a longer mean timeline for return to sport compared with men (women: 245.2 ± 288.2 days, men: 179.3 ± 231.9 days, P = 0.014).

CONCLUSION

Sesamoiditis was the most common diagnosis, and dance, running, and soccer were top 3 sports. The most salient finding was that women taking almost twice as long to return the sport or activity compared with men, which likely stems from delay of reporting symptom onset to clinics.

Early Warning of Basketball Injury Risk Based on Attribute Reduction Algorithm

Basketball is one of the students' favorite ball games, and it is also one of the most popular sports for college students to carry out after class. Especially in recent years, with the spread of NBA culture around the world and the extensive development of CUBA in domestic colleges and universities, Yao Ming has appeared in China to compete in the NBA and achieve brilliant achievements. With the increasing investment in the number of basketball venues, basketball itself, as a sport with low dependence on venues, equipment, and people, has the characteristics of economy, convenience, and remarkable sports effect compared with other sports. College students' basketball skills, basketball awareness, and love for basketball are increasing day by day. Attribute reduction algorithm is one of the core contents of knowledge discovery, which describes whether every attribute in the attribute set of information system is necessary and how to delete unnecessary knowledge. Based on the attribute reduction algorithm, this paper studies the early warning of basketball injury risk. The basketball injury can not only make athletes unable to participate in training or competition, but even cripple or lose their lives, which hinders the normal development of sports. Therefore, we should make a comprehensive and objective analysis of sports training to find out the causes of sports injuries, so as to prevent sports injuries. This algorithm takes the attribute frequency as the heuristic information and solves the attribute selection problem when the attribute frequency is the same.

Epidemiology and injury trends in the National Basketball Association: Pre- and per-COVID-19 (2017-2021)

Purpose

The aim this study was to provide an epidemiological injury analysis of the National Basketball Association, detailing aspects such as frequency rate, characteristics and impact on performance (missed games), including COVID-19 related and non-related injuries.

Methods

A retrospective study was conducted from the 2017–18 to 2020–2021 season. Publicly available records from the official website of the National Basketball Association were collected, including player’s profiling data, minutes played per game until the injury occurred, unique injuries and injury description [location (body area), diagnosis (or mechanism)], and missed games due to injury.

Results

A total of 625 players and 3543 unique injuries were registered during the period analyzed. There was an increased incidence of missed games and unique injuries ratios, from 2017–18 until 2020–21, even when excluding COVID-19 related cases. The main body areas of injuries corresponded to lower body injuries, specifically knee, ankle and foot. The tendon/ligament group, for both games missed and unique injuries, showed the higher ratios (1.16 and 0.21, respectively), followed by muscle (0.69 and 0.16, respectively) and bones (0.30 and 0.03, respectively). Irrespective of season, the higher percentage of unique injuries occurred in the group of players playing in the 26–35 minutes, followed by the 16–25 minutes played. Guards showed the highest injury ratios compared to other playing positions. Most injuries and missed games due to injury occurred from mid-season to the end of the regular season. The majority of both injuries and missed games were concentrated in the two central experience groups (from 6 to 15 years).

Conclusions

Despite previous efforts to better understand injury risk factors, there has been an increase in unique injuries and missed games. The distribution by body area, type of injury, when they occurred, minutes played and outcomes by play position, age a or years of experience vary between season and franchises.

Honey on Basketball Players' Physical Recovery and Nutritional Supplement

Sports injury is a subject that every athlete will face, and it is the easiest to happen in training and competition, especially for basketball players. Moreover, the excessive fatigue caused by sports not only reduces the person's ability to play sports, but also it reduces the person's participation in normal training and competition. Sugar and fat play a dominant role in energy metabolism, while protein only plays an auxiliary role. For competitive sports, sugar is the most important energy, and the main components of honey are glucose and fructose. Therefore, this paper attempts to explore the effect of honey on the physical recovery and nutritional supplement of basketball players. In this paper, 10 basketball players in our city were selected as the experimental objects and the data of their physiological and biochemical indexes were analyzed. The results showed that the average hemoglobin of the experimental group decreased from 14.45 g·100 ml-1 in the first week to 13.23 g·100 ml-1 in the second week, increased to 14.25·100 ml-1 in the third week, and increased to 15.79.100 ml-1 in the fourth week. Adding honey can improve the content of HB and CK of basketball players in higher vocational colleges and reduce the increase of BUN, to slow down fatigue and accelerate the speed of physical recovery.

Characterization of Rookie Season Injury and Illness and Career Longevity Among National Basketball Association Players

IMPORTANCE

There is limited research investigating injury and illness among professional basketball players during their rookie season. By improving the understanding of injury incidence and risk specific to rookie players, sports medicine clinicians may be able to further individualize injury mitigation programs that address the unique needs of rookie players.

OBJECTIVE

To compare incidence and rate ratio (RR) of injury and illness among professional National Basketball Association (NBA) players in their rookie season with veteran players and to explore the association of sustaining an injury rookie season with career longevity.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study used an online data repository and extracted publicly available data about NBA players between the 2007 and 2008 season to the 2018 and 2019 season. Available data for initial injury and all subsequent injuries were extracted during this time frame.

EXPOSURES

Injury and illness based on injury status during the rookie season of professional NBA players.

MAIN OUTCOMES AND MEASURES

Injury and illness incidence and RR. Association of injury during the rookie season with career longevity was assessed via Poisson regressions.

RESULTS

Of the 12 basketball seasons analyzed, 904 NBA players were included (mean [SD] age, 24.6 [3.9] years; body mass index, 24.8 [1.8]). The injury and illness incidence for rookie players was 14.28 per 1000 athlete game exposures (AGEs). Among all body regions, ankle injuries had the greatest injury incidence among players injured during their rookie season (3.17 [95% CI, 3.15-3.19] per 1000 AGEs). Rookie athletes demonstrated higher RR compared with veterans across multiple regions of the body (ankle: 1.32; 95% CI, 1.12 to 1.52; foot/toe: 1.29; 95% CI, 0.97 to 1.61; shoulder/arm/elbow: 1.43; 95% CI, 1.10 to 1.77; head/neck: 1.21; 95% CI, 0.61 to 1.81; concussions: 2.39; 95% CI, 1.89 to 2.90; illness: 1.14; 95% CI, 0.87 to 1.40), and demonstrated a higher rate of initial injuries compared with veteran players (1.41; 95% CI, 1.29 to 1.53). Players who sustained an injury rookie season demonstrated an unadjusted decrease in total seasons played (-0.4 [95% CI, -0.5 to -0.3] log years; P < .001), but this decrease was not observed within adjusted analysis (0.1 [95% CI, -0.1 to 0.2] log years; P = .36).

CONCLUSIONS AND RELEVANCE

In this study, rookie athletes demonstrated the highest injury incidence at the ankle and increased RR across multiple regions. These findings may reflect differences in preseason conditioning or load variables impacting rookie athletes and warrant further investigation. Future research is needed to determine the association of cumulative injury burden vs a singular injury event on career longevity.

Local dynamic stability of the lower-limb as a means of post-hoc injury classification

Since most sporting injuries occur at the lower extremity (50% to 66%) and many of those injuries occur at the knee (30% to 45%), it is important to have robust metrics to measure risk of knee injury. Dynamic measures of knee stability are not commonly used in existing metrics but could provide important context to knee health and improve injury screening effectiveness. This study used the Local Dynamic Stability (LDS) of knee kinematics during a repetitive vertical jump to perform a post-hoc previous injury classification of participants. This study analyzed the kinematics from twenty-seven female collegiate division 1 (D1) soccer, D1 basketball, and club soccer athletes from Auburn University (height = 171 ± 8.9cm, weight = 66.3 ± 8.6kg, age = 19.8 ± 1.9yr), with 7 subjects having sustained previous knee injury requiring surgery and 20 subjects with no history of injury. This study showed that LDS correctly identified 84% of previously injured and uninjured subjects using a multivariate logistic regression during a fatigue jump task. Findings showed no statistical difference in kinematic position at maximum knee flexion during all jumps between previously injured and uninjured subjects. Additionally, kinematic positioning at maximum knee flexion was not indicative of LDS values, which would indicate that future studies should look specifically at LDS with respect to injury prevention as it cannot be effectively inferred from kinematics. These points suggest that the LDS preserves information about subtle changes in movement patterns that traditional screening methods do not, and this information could allow for more effective injury screening tests in the future.

Concussion Epidemiology in Athletes Who Are Deaf or Hard-of-Hearing Compared With Athletes Who Are Hearing

OBJECTIVE

To compare the epidemiology of concussion between athletes who are deaf or hard-of-hearing (D/HoH) and athletes who are hearing.

DESIGN

Descriptive epidemiology study.

SETTING

Data were collected from 2 Division III athletic programs. One institution is the world's only university designed to be barrier-free for students who are D/HoH.

PARTICIPANTS

Six hundred ninety-three athletes who are D/HoH and 1284 athletes who are hearing were included in this study. Athletes participated in collegiate athletics during the 2012 to 2013 through the 2016 to 2017 academic years.

INTERVENTIONS

Concussion data were provided by the athletic training staff at each institution.

MAIN OUTCOME MEASURES

Concussion counts, concussion rate, and injury rate ratios (IRRs) with 95% confidence intervals (95% CIs).

RESULTS

Thirty athletes who are D/HoH and 104 athletes who are hearing suffered concussions. Athletes who are hearing had an increased injury rate compared with athletes who are D/HoH for all sports combined (IRR = 1.87, 95% CI, 1.26-2.78). Football athletes who are hearing also had an increased injury rate compared with football athletes who are D/HoH (IRR = 3.30, 95% CI, 1.71-6.37). Concussion rate was higher for male athletes who are hearing than male athletes who are D/HoH (IRR = 2.84, 95% CI, 1.62-4.97). No other significant differences regarding concussion risk were identified.

CONCLUSIONS

Athletes who are D/HoH in sex-comparable sports may not have a higher rate of concussion than athletes who are hearing. Rate of concussion in football may be greater among athletes who are hearing compared with athletes who are D/HoH.

A demographic study of acute injuries in basketball players

Studies that analyse the epidemiology of acute injuries in basketball players in European countries are limited. The purpose is to present an overview of the incidence of injuries and injury patterns in Flanders and to correlate them to possible intrinsic and extrinsic risk factors. All acute injuries that occurred in Flanders during 2009-2013, collected by the insurance, were analysed. The incidence and parameters such as date of birth, date of occurrence of the injury, gender and diagnosis were evaluated. Injury incidence varied from 7.40% up to 8.45%. Females and players at age 16-17, 14-15 and older than 30 are at higher risk. The ankle/foot region is most frequently injured. There is a higher risk of injury after season-and Christmas break. Age, gender and chronometry are risk factors to get injured. Sprains are the most frequent, while the nkle/foot region is the most susceptible to injury. Studies that analyse the epidemiology of acute injuries in basketball players in European countries are limited. Female players and players at age 16-17, 14-15 and older than 30 are at higher risk to basketball injuries. The ankle/foot region is most frequently injured followed by lower arm and hand. There is a higher risk of injury after season-and Christmas break.

One Session of Extracorporeal Shockwave Therapy-Induced Modulation on Tendon Shear Modulus is Associated with Reduction in Pain

The aim of the study was to examine the immediate effect of 1 session of extracorporeal shockwave therapy (ESWT) on patellar tendon stiffness and to explore the relationship between the change in tendon stiffness and the pain intensity. Thirty-four male athletes aged 22.2 ± 3.8 with patellar tendinopathy were recruited. The participants were randomized into ESWT and sham groups. The ESWT group received 1500 impulses of ESWT at 4 Hz with maximal tolerable pain intensity and the sham group received intensities below 0.08 mJ/mm². Supersonic Shearwave Imaging (SSI) was used to measure tendon shear modulus (an index of tissue stiffness), and a visual analogue scale was used to quantify the pain intensity during compression with 10 lb (4.535 kg) pressure directed on the most tender part and then during a single-leg declined-squat test. A significant reduction in tendon shear modulus (from 57.4 ± 25.5 kPa to 40.6 ± 17.6kPa, p = 0.001) was detected in the ESWT receiving ESWT with an intensity from 0.13-0.33 mJ/mm² but not the sham group (from 47.7 ± 17.1 kPa to 41.0 ± 12.7 kPa; p = 0.06). In the ESWT group, the change in tendon shear modulus was associated with the change in the intensity of pain during single-legged declined-squat test (ρ = 0.55; p = 0.023) but not pressure pain (p > 0.05). These findings suggest that one session of ESWT induces reduction of tendon stiffness in volleyball and basketball players with patellar tendinopathy. The reduction in tendon stiffness is associated with reduction in pain during single-legged declined-squat test.

Injury surveillance of an Australian community netball club

OBJECTIVES

To describe injuries associated with netball and risk factors for lower limb injuries.

DESIGN

Prospective study. In the preseason, risk factors were investigated using self-report questionnaires and physical measurements. During the season, injuries were reported using a standardised report, verified by follow-up phone calls. Player training and game hours were recorded.

SETTING

Australian community netball club.

PARTICIPANTS

269 players from 9 divisions, aged 7-42 years.

MAIN OUTCOME MEASURES

Injury incidence rates per 1000 exposure hours were calculated. The most common mechanism, nature and consequence of injury were determined from frequencies. Logistic regression was used to identify predictors of lower limb injury and determine adjusted odds ratios for each risk factor.

RESULTS

169 injuries occurred with a rate of 13.8/1000 exposure hours (95% CI 11.8-16.0), majority (60%) to the lower limb. The most frequent injury mechanisms were collisions (28%) and awkward landings (27%), nature was 'Inflammation/swelling' (32%) and consequence was 'unable to continue playing/training' (50%). Previous history of injury (OR 6.9, 95% CI 3.7-13.0) and age greater than 13.5 years (OR 3.1, 95% CI 1.6-5.9) were significant risk factors for a season lower limb injury.

CONCLUSION

Injury rates in this community netball club were high. Results suggest that further research regarding the implementation and effectiveness of injury prevention programs for community netballers is required.

Performance and Return to Sport After Hip Arthroscopy in the National Basketball Association

PURPOSE

To determine: (1) return to sport (RTS) rate in National Basketball Association (NBA) players following hip arthroscopy, (2) postoperative career length and games per season, (3) pre- and postoperative performance, and (4) postoperative performance compared with control players.

METHODS

NBA athletes who underwent hip arthroscopy and matched controls were identified. RTS was defined as playing in at least 1 game after surgery. Player efficiency ratings were used for performance evaluation. Continuous variables of each group were compared using a 2-tailed paired samples Student t test for normally distributed data. χ² was used to analyze categorical data. RTS was used as the primary outcome with statistical significance defined by a P value < .05. A Bonferroni correction was used to control for the remaining multiple comparisons with statistical significance defined by a P value ≤.008.

RESULTS

Twenty-three players (24 hips) were analyzed (mean age 27.5 ± 3.1 years; mean experience in the NBA 5.8 ± 2.8 years at time of surgery). Small forwards (n = 8, 33.3%) represented the largest proportion of players that underwent hip arthroscopy. Twenty players (21 surgeries, 87.5%) were able to RTS in NBA at an average of 5.7 ± 2.6 months. The overall 1-year NBA career survival rate of players undergoing hip arthroscopy was 79.2%. Players in the control group (5.2 ± 3.5 years) had a similar career length as (P = .068) players who underwent surgery (4.4 ± 3.0 years). There was no significant (P = .045) decrease in games per season following surgery. There was no significant difference in performance postoperatively compared with preoperatively (P = .017) and compared with matched controls following surgery (P = .570).

CONCLUSIONS

The RTS rate for NBA athletes after hip arthroscopy is high. There was no decrease in games played, career lengths, or performance following hip arthroscopy in NBA players versus preoperatively and matched controls.

LEVEL OF EVIDENCE

Level III case-control study.

Return to play and performance after shoulder instability in National Basketball Association athletes

HYPOTHESIS

We hypothesized that players in the National Basketball Association (NBA) who sustained a shoulder destabilizing injury could return to play (RTP) successfully at a high rate regardless of treatment type.

METHODS

We used publicly available data to identify and evaluate 50 players who sustained an in-season shoulder instability event (subluxation/dislocation) while playing in the NBA. Demographic variables, return to NBA gameplay, incidence of surgery, time to RTP, recurrent instability events, and player efficiency rating (PER) were collected. Overall RTP was determined, and players were compared by type of injury and mode of treatment.

RESULTS

All players (50/50) returned to game play after sustaining a shoulder instability event. In those treated nonoperatively, athletes who sustained shoulder subluxations returned after an average of 3.6 weeks, compared with 7.6 weeks in those who sustained a shoulder dislocation (P = .037). Players who underwent operative management returned after an average of 19 weeks. Athletes treated operatively were found to have a longer time interval between a recurrent instability event (70 weeks vs. 28.5 weeks, P = .001).

CONCLUSION

We found 100% rate of RTP after a shoulder instability event in an NBA athlete. Players who experience shoulder dislocations were found to miss more time before RTP and were more likely to undergo surgical intervention compared with those who experienced a subluxation. Surgical repair maintained a longer interval between recurrent instability. Future investigations should aim to evaluate outcomes based on surgical procedures and identify possible risk factors predictive of recurrent instability or failure to RTP.

Acetabular Fracture Resulting from a Basketball Cutting Movement in a Young Adult Male: A Case Report

CASE

We present the case of a 26-year-old man who sustained a right transverse-posterior wall acetabular fracture while performing a cutting movement playing basketball.

CONCLUSIONS

Acetabular fracture after a relatively low-energy injury in a healthy young adult male is an extremely unusual event. The cutting movement to the right likely forcefully placed the right hip in flexion, adduction, and internal rotation directing the femoral head into the posterior wall. The patient had excellent clinical and radiographic results after acetabular open reduction and internal fixation.

Effect of Shoulder Stabilization on Career Length and Performance in National Basketball Association Athletes

PURPOSE

Untreated episodes of shoulder instability can have major consequences on athletic careers. Operative shoulder stabilization reduces the rate of recurrent instability and allows for high rates of return to sport (RTS). Basketball players who experience an episode of instability have high rates of recurrence, though little is known about postoperative player performance. The purpose of this study was to identify the impact of shoulder instability and surgical stabilization on player performance and career lengths in the National Basketball Association (NBA).

METHODS

NBA players who had episodes of shoulder instability between 1994-2014 were identified using the NBA Injury Surveillance and Analytics Database. Players were stratified according to operative versus nonoperative treatment of shoulder instability. Two demographic- and performance-matched controls were chosen for each test subject. Univariate analyses were used to compare pre- and postoperative player performance metrics. Survival analysis was used to assess the effect of shoulder surgery on postoperative career lengths.

RESULTS

Fifty athletes were identified, 46 (92.0%) returned to play in the NBA. Compared to controls, there was no significant difference in postoperative performance according to either 1- or 3-year averages. Survival analysis demonstrated no significant difference in postoperative career lengths between athletes with a history of shoulder surgery for instability and matched controls.

CONCLUSION

NBA players return to professional basketball in high numbers following orthopedic surgery for shoulder instability. Shoulder instability may not be a career-altering event, as there are highly effective methods of shoulder stabilization available to athletes.

Median Nerve Entrapment in the Ulna in a Both-Bone Pediatric Forearm Fracture: Case Report and Review of the Literature

This case report presents entrapment with subsequent complete disruption of the median nerve in the distal ulna in a both-bone fracture of the forearm in a 9-year-old girl. Closed fractures of the radius and ulna commonly occur in pediatric populations. Postinjury nerve dysfunction is often seen. Severe nerve injury is rare. There are only 3 reports of the median nerve becoming entrapped in an ulnar fracture in a child, with no reports of entrapment in the distal forearm. Features seen on examination and the radiographs supported possible nerve entrapment. Although uncommon, nerve entrapment or transection should be considered in all forearm fractures with sensory or motor nerve dysfunction. If suspicions are high, an early diagnosis of nerve entrapment may be obtained with magnetic resonance imaging evaluation.

Effectiveness of Warm-Up Routine on the Ankle Injuries Prevention in Young Female Basketball Players: A Randomized Controlled Trial

Background and Objectives: Ankle joint is the most common site of injury for basketball athletes. An effective warm-up (WU) is a period of preparatory exercise to improve training performance and reduce sports injuries. Continuous examination of effective WU routines in basketball players is a necessity. The aim of this study was to investigate the effects of general and combined warm up on ankle injury range of motion (ROM) and balance in young female basketball players. Materials and Methods: A sample of 28 young female basketball players were randomly allocated to either global warm up control group (GWU) (n = 11) or combined warm up experimental group (CWU) (n = 17). All participants performed 7-min of run. The CWU group performed a single leg stance barefoot with eyes closed, plank forearm position and triceps sural stretching. Participants in GWU performed walking ball handling and core stability using a Swiss ball. Both WU routines were conducted 3 times per week for 10 weeks. Outcome measurements were the Stabilometric platform and dorsiflexion lunge test. Results: Twenty-eight young female basketball players completed the study. Participants in the experimental group improved significantly in the range of motion (ROM) in right and left ankle and the center of pressure displacement (CoP). The control group did not show any changes in ankle dorsiflexion and a significant reduction in all body balance parameters. Conclusions: An 8-min combined warm-up routine for 10 weeks improves the ankle dorsiflexion ROM and CoP displacement that plays a key role in ankle injuries prevention in basketball players. Further studies are strongly needed to verify our findings.

Open ligamentous complex disruption of the lateral ankle without dislocation or fracture: Two case reports

INTRODUCTION

Lateral ligamentous complex injury without fracture or dislocation is rare in the literature. Due to the rare injury, it is not clear yet about the proper treatment. This case report suggests a specific diagnosis of this injury as well as an appropriate surgical method.

PATIENT CONCERNS

In one-month period of time, 2 male soldiers participating in recreational basketball game presented with open wound on the lateral aspect of ankle without associated dislocation or fracture when they attempted to rebound the ball which consequently made them land on another player's foot.

DIAGNOSIS

Total rupture of the lateral ligament complex with open wound was found without any associated fracture or dislocation.

INTERVENTIONS

Open repair of the ruptured ligaments and capsule was performed.

OUTCOMES

Patients returned to his own job's duty with none to minimal limitation in sport and activities of daily living at 9 to 10 months after the injury.

CONCLUSION

Although open disruption of the lateral ligamentous complex without fracture or dislocation is rare, an adequate assessment and prompt surgical repair led to satisfactory outcome.
