ABSTRACT
CONTEXT: For this case series, 4 student-athletes (age range = 20-22 years) participating in National Collegiate Athletic Association Division I ice hockey served as cases. They were free of injury and participated in all team activities without restrictions. TREATMENT: A dry needling (DN) lower extremity recovery protocol was completed for all athletes during a single session. To administer the DN recovery treatment, we placed static needles in specific bilateral locations that consisted of 5 points on both the anterior and posterior aspects of the lower extremity and lumbopelvic complex. The Acute Recovery Stress Scale was used to evaluate the effect of the DN recovery treatment on each athlete's perception of recovery at 24 and 48 hours post-DN treatment. RESULTS: Overall, total and average scores of Acute Recovery Stress Scale for all cases were closer to baseline at 48 hours post-DN than at the other time points. CONCLUSIONS: Recovery techniques historically have been used postactivity because even normal training loads, which are considered positive, produce stress and fatigue in athletes and can lead to injury. Results from this case series suggest that ice hockey athletes who are experiencing postexercise stress, such as soreness and fatigue, may benefit from a lower extremity DN recovery treatment protocol.

OBJECTIVE: To evaluate whether participating in physical contact sports is associated with a release of neurofilaments and whether such release is related to future clinical neurologic and/or psychiatric impairment. METHODS: We performed a systematic review of the PubMed, MEDLINE, and Cochrane Library databases using a combination of the search terms neurofilament(s)/intermediate filament and sport(s)/athletes. Original studies, written in English, reporting on neurofilaments in CSF and/or serum/plasma of contact sport athletes were included. This review was conducted following the Preferred Reporting Items for Systematic Review and Analyses guidelines. RESULTS: Eighteen studies in 8 different contact sports (i.e., boxing, American football, ice hockey, soccer, mixed martial arts, lacrosse, rugby, and wrestling) matched our criteria. Elevated light chain neurofilament (NfL) levels were described in 13/18 cohorts. Most compelling evidence was present in boxing and American football, where exposure-related increases were appreciable at the intraindividual level (up to 4.1- and 2.0-fold, respectively) in well-defined groups. Differences in exposure severity (including previous cumulative effects), sampling/measurement time points (with regard to expected peak values), and definitions of the baseline setting are considered as main contributors to the variability in findings. No studies were encountered that have investigated the relationship with the targeted clinical end points; therefore no NfL cutoffs exist that are associated with a poor outcome. CONCLUSION: NfL release can be seen, as a potential marker of neuronal brain damage, in participants of physical contact sports, particularly boxing and American football. The exact significance regarding the risk for future clinical impairment remains to be elucidated.

OBJECTIVES: The novel MOTor Imagery to Facilitate Sensorimotor Re-Learning (MOTIFS) model takes a uniquely holistic approach by integrating mental and physical aspects into current training programs. The aim of this trial was to evaluate enjoyment of MOTIFS training as compared to Care-as-Usual (CaU) knee injury and/or rehabilitation training. The primary hypothesis was that enjoyment would be greater following MOTIFS training than CaU training. DESIGN: Block-randomized 2×2 cross-over trial. METHODS: Thirty athletes (18-31years, 50% women) currently or previously active in team ball sports, with no pain or injury preventing jump and/or directional changes. MOTIFS training integrates sport-specific experiences and equipment into physical exercises to increase individualized realism and meaning. The CaU condition included solely physical exercise. The main outcome was the Physical Activity Enjoyment Scale (PACES). Secondary outcomes included Self-Assessment Manikin (SAM; subscales Valence, Arousal, Dominance), Perceived exertion, pulse, duration, and movement quality. RESULTS: PACES scores were better following MOTIFS training than CaU (point estimate 24.67; 95% CI: 19.0; 30.3). Between-groups differences in SAM Valence (median 2, quartiles 1;3), Arousal (median 1, quartiles 0;2.25), and Dominance (median 0.5, quartiles 0;2), and RPE (median 1, quartiles -0.3;2), training duration (mean 5.34, 95% CI: -0.17; -0.73), and pulse (median 7.50, quartiles 0.25;16.75) were higher following MOTIFS training than CaU training. CONCLUSIONS: Results suggest that the MOTIFS model, which integrates simultaneous physical and psychological interventions, is a clinically plausible method of influencing enjoyment and other psychological outcomes. Further studies may explore effects of the MOTIFS principles on injury prevention and rehabilitation training.

The incidence of sport-related concussion coupled with a doubling of the participation rate in youth hockey over the past two decades provides impetus for the review of the most promising concussion treatment options. This narrative review summarizes the future treatment options for sport-related concussions in ice hockey, while acknowledging their generalizability to concussion in all sports. Symptom assessment, sign observation, as well as cognitive and balance testing, have historically been used to diagnose a concussion. These methods continue to improve, but the need for effective treatments is clear. Pharmacologic, transcranial light, and nutritional supplement treatment options for concussion warranting further investigation have been identified. Dimethyl fumarate is an immunomodulatory compound thought to trigger antioxidant gene expression. Memantine reduces apoptosis and astrogliosis by inhibiting the calcium influx into cells normally caused by glutamate's activation of N-methyl-D-aspartate receptors. Thioredoxin-mimetic peptides and transcranial photobiomodulation temper the effects of the energy crisis by acting as free radical scavengers. In addition, seven neuroprotective nutritional supplements have been identified: berberine, creatine, curcumin, melatonin, omega-3 fatty acids, resveratrol, and vitamins. An estimated US $1.1 billion has been spent on unsuccessful traumatic brain injury clinical trials. As our ability to accurately diagnose concussion improves, dimethyl fumarate, memantine, thioredoxin-mimetic peptides, transcranial photobiomodulation, and nutritional supplements (berberine, creatine, curcumin, melatonin, omega-3 fatty acids, resveratrol, and vitamins) warrant further preclinical and clinical examination in advancing the treatment of sport-related concussions.

BACKGROUND: Pain pressure thresholds (PPT) have not been investigated when Active Release Techniques (ART(®)) is directed at treating soft tissue injuries. AIM: To investigate the immediate effects of ART(®) employed in the management of adductor muscle strains to modulate pain threshold. METHODS: Patients were administered ART(®) commensurate with the extent and nature of their adductor muscle injury. The outcome measureused was PPT over the adductor muscle strain which was assessed pre-intervention and 2min post-intervention. RESULTS: Within group effect sizes were calculated using a paired samples t-test to assess clinical effect. The mean pre-intervention and 2min post-intervention PPT values were 4.2±0.83 and 5.3±0.99 significantly different (p<0.001). CONCLUSION: The application of ART(®) to treat groin strains may be of benefit in increasing pain thresholds amongst ice-hockey players. Future research requires sufficient sample sizing, a control group, and correlations with objective outcome measures (VAS and range of motion) to validate the therapeutic effect of ART(®).

Low back pain (LBP) is a common health problems. Although it is multifactorial, its treatment varies considerably, including medication, physical therapy modalities, and exercise therapy, and each have several interventions. Despite their effectiveness, their head-to-head comparisons are limited. This study was aimed at 1 such comparison. A total of 30 hockey players, 18 to 28 years of age, with subacute or chronic LBP were randomly assigned equally in 2 groups. One group was treated with conventional treatment--a combination of 2 electrotherapies (ultrasound and short-wave diathermy) and 1 exercise therapy (lumbar strengthening exercises)--and the other group was treated with dynamic muscular stabilization techniques (DMST), an active approach of stabilizing training. The results showed that both the treatments are effective in the management of LBP, but DMST was found to be more effective than conventional treatment. The walking, stand ups, climbing, and pain improved 4.7, 2.0, 1.4, and 2.1 times, respectively, more with DMST than with conventional treatment. With time (days), walking, stand ups, climbing, and pain improved (correlation) significantly (p < 0.01) higher in DMST (r = 0.83 to 0.92) than in conventional treatment (r = 0.40 to 0.75), and their rate of improvement (regression beta coefficients) were also significantly (p < 0.01) higher in DMST (beta = -0.16 to 0.73) than in conventional treatment (beta = -0.07 to 0.15). Subjects matching were perfect (p < 0.01) and test-retest reliability of all dependent variables was significantly (p < 0.01) high (intraclass correlation coefficient approximately 1). No major adverse effects were recorded in any of the patients in either group. This study concluded that for early recovery, DMST is more suitable than conventional treatment.

OBJECTIVE: This study assessed the immediate effects of talocrural joint manipulation on stabilometric and baropodometric outcomes in patients with grade II ankle sprain. METHODS: Fifty-two field hockey players (35 men and 17 women) between 18 and 40 years old (mean = 22.5 years, SD = 3.6 years) were included in this study. A simple blind, intrapatient, placebo-controlled, and repeated-measures study was carried out. All the patients underwent a baropodometric study performed with a Foot Work force platform (4 times; pre-post placebo group and pre-post intervention group). The sample was subjected to two techniques of manipulative treatment: (a) talocrural joint manipulation and (b) posterior gliding manipulation over the talus. In a second instance, placebo manipulation was applied. Unilateral analysis of variance and multivariate analysis of variance were used for statistical analysis. RESULTS: The results in the intervention group revealed significant differences in the percentage of posterior load on the foot (P = .015) and the percentage of bilateral anterior load (P = .02) before and after the manipulation. The placebo group did not show any change in any of the variables except for area (P = .045). Intergroup comparison revealed statistically significant differences in the increase in percentage of posterior load on the manipulated foot, percentage of bilateral posterior load, percentage of anterior load on the manipulated foot, and percentage of bilateral anterior load (with the exception of the total load on the foot). CONCLUSIONS: The application of caudal talocrural joint manipulation, as compared with placebo manipulation, in athletic patients with grade II ankle sprain redistributed the load supports at the level of the foot.

CONTEXT: Few studies have examined psychological and emotional processes in injury rehabilitation from a longitudinal, theoretically framed perspective. OBJECTIVE: This study explored the applicability of Reversal Theory to examine these processes. SETTING: University of Wales, Aberystwyth, UK. PARTICIPANTS: Three severely injured athletes; two were female (karate and judo) and one was male (hockey), aged 20 to 28. MAIN OUTCOME MEASURES: Fortnightly interviews after participant's initial consultation with a sports therapist, until complete physical rehabilitation. RESULTS: Supported the use of Reversal Theory in this context (eg, as a means of understanding the origins of athletes' emotional responses to injury and changes in these responses throughout rehabilitation). CONCLUSIONS: Suggestions for future research are made (eg, examining the consequences of emotional and metamotivational states for athlete behavior and recovery outcomes during rehabilitation).

Sports are part of the sociocultural fabric of all countries. Although different sports have their origins in different countries, many sports are now played worldwide. International sporting events bring athletes of many cultures together and provide the opportunity not only for athletic competition but also for sociocultural exchange and understanding among people. This article reviews five major sports with international appeal and participation: cricket, martial arts, field hockey, soccer, and tennis. For each sport, the major aspects of physiological and biomechanical demands, injuries, and prevention strategies are reviewed.

The objective of the present work was to study the occurrence of dental trauma in different sports, as well as to check if athletes used mouthguard during sport activities, and knew the significance of its utilization. The professional and semi-professional athletes who practised contact sports were interviewed, and were analyzed to determine the occurrence of dental trauma during sport practice, as well as if the athletes used a mouthguard and knew its indication. Results showed a high rate of dental trauma in athletes compared to the general population. The majority of athletes also demonstrated little utilization of mouthguard, in spite of the information about usage during sports practices and a general knowledge of its uses.

OBJECTIVE: Despite the rise in specialist clinical services for the management of sports and active recreation injury, many patients attend hospital emergency departments for treatment. The purpose of this study was to describe sports injury cases presented to selected hospital emergency departments around Australia for the period 1989-1993. METHODS: Routinely collected emergency department injury presentation data from the Australian National Injury Surveillance Unit were examined. Data on 98,040 sports and active recreation emergency department presentations were analysed. Sports and active recreation activities were ranked according to frequency of presentation. Relative proportions of injury type and body region injured were determined. Data are presented separately for children (<15 years of age) and adults (>15 years of age). RESULTS: Among the 10 activities that most commonly led to a sports or active recreation injury presentation for all ages were cycling, Australian football, basketball, soccer, cricket, netball, and rugby. For children, injuries were also commonly associated with roller skating/blading, skateboarding, and trampolining. Hockey, martial arts, and dancing injuries were frequent in adults. Most sporting injuries occurred during organised competition or practice whereas the active recreation injuries occurred in a variety of settings. Fractures, strains, and sprains, particularly to the lower and upper extremities, were common types of injury. CONCLUSION: The rich, but nevertheless limited, information available about sports and active recreation injuries from data collected in emergency departments indicates that these activities are a common context for injury at the community level in Australia.

OBJECTIVE: To determine the acute injury profile in each of six sports and compare the injury rates between the sports. DESIGN: Analysis of national sports injury insurance registry data. SETTING: Finland during 1987-91. SUBJECTS: 621,691 person years of exposure among participants in soccer, ice hockey, volleyball, basketball, judo, or karate. MAIN OUTCOME MEASURES: Acute sports injuries requiring medical treatment and reported to the insurance company on structured forms by the patients and their doctors. RESULTS: 54,186 sports injuries were recorded. Injury rates were low in athletes aged under 15, while 20-24 year olds had the highest rates. Differences in injury rates between the sports were minor in this adult age group. Overall injury rates were higher in sports entailing more frequent and powerful body contact. Each sport had a specific injury profile. Fractures and dental injuries were most common in ice hockey and karate and least frequent in volleyball. Knee injuries were the most common cause of permanent disability. CONCLUSIONS: Based on the defined injury profiles in the different sports it is recommended that sports specific preventive measures should be employed to decrease the number of violent contacts between athletes, including improved game rules supported by careful refereeing. To prevent dental injuries the wearing of mouth guards should be encouraged, especially in ice hockey, karate, and basketball.

BACKGROUND: Sudden death from cardiac arrest in a young person may occur during sports play after a blunt blow to the chest in the absence of structural cardiovascular disease or traumatic injury (cardiac concussion or commotio cordis). We studied the clinical features of this apparently uncommon but important phenomenon. METHODS: We identified cases from the registries of relevant agencies and organizations, as well as newsmedia accounts, and developed a clinical profile of 25 children and young adults, 3 to 19 years of age. RESULTS: Each victim collapsed with cardiac arrest immediately after an unexpected blow to the chest, which was usually inflicted by a projectile (such as a baseball or hockey puck). Incidents took place during organized competitive sports in 16 cases and in recreational settings at home, at school, or on the playground in 9. In each instance, the impact to the chest was not judged to be extraordinary for the sport involved and did not appear to have sufficient force to cause death. Twelve victims collapsed virtually instantaneously on impact, whereas 13 remained conscious and physically active for a brief time before cardiac arrest. Cardiopulmonary resuscitation was administered within about three minutes to 19 victims, but normal cardiac rhythm could be restored in only 2 (both incurred irreversible brain damage and died shortly thereafter). Seven victims (28 percent) were wearing some form of protective chest padding. CONCLUSIONS: We speculate that most sudden deaths related to impact to the chest (not associated with traumatic injury) are due to ventricular dysrhythmia induced by an abrupt, blunt precordial blow, presumably delivered at an electrically vulnerable phase of ventricular excitability. This profile of blunt chest impact leading to cardiac arrest adds to our understanding of the range of causes of sudden death on the athletic field and may help in the development of preventive measures.

OBJECTIVE: To present a case of myositis ossificans traumatica (MOT) in a hockey player. Serial X-ray studies allow the reader an opportunity to observe MOT in its earliest through fulminated stages. CLINICAL FEATURES: A 20-yr-old hockey player was subjected to an acute blow to the lateral thigh. Copious amounts of swelling soon developed. The patient was unable to skate. X-rays were initially performed 4 hr after the injury and demonstrated a hugh mass developing in the thigh at that time. INTERVENTION AND OUTCOME: The player was inappropriately treated with deep tissue massage and heat at the time of injury. It is believed that this led to the fulmination and advanced degree of MOT development. Immobilization allowed for resorption of the calcific density of the ossified structure. CONCLUSION: Proper care of acute trauma is essential in disorders of this nature. Ice, immobility and recognition of when a possible MOT lesion is developing is essential when dealing with contact sports.
