Psychological impact of injuries in athletes.

Although research on the psychological impact of injury is in its infancy, this article reviews relevant literature focusing on post-injury emotional response, self-esteem, and the effect of mood disturbance on rehabilitation from sport injury. Injury is often accompanied by depression, tension, anger and low self-esteem, particularly in competitive, seriously injured athletes. Mood disturbance seems to relate to the athlete's perceived progress in rehabilitation and has been shown to negatively relate to attendance at rehabilitation sessions. This article also describes how the Emotional Responses of Athletes to Injury Questionnaire (ERAIQ) serves as a guide for the initial interview of an injured athlete. Interventions such as positive self-talk, relaxation, goal setting and healing imagery, all used by a faster healing group of athletes, and although not well researched, seem appropriate to assist athletes in coping with injury. Modelling interventions during injury rehabilitation have also been shown to have a positive effect on rehabilitation and should be used. These relationships are described in more depth and in the context of a theoretical model. Directions for future research are suggested.

MR imaging of the distribution and location of acute hamstring injuries in athletes.

OBJECTIVE: Although hamstring injuries are common in athletes, the distribution and location of such injuries have not been well defined. We used MR imaging to determine the frequency of injury by muscle, involvement of one or more muscles, and location of injuries within the musculotendinous unit. SUBJECTS AND METHODS: We performed MR imaging on 15 consecutive college athletes with clinically diagnosed acute hamstring injuries. A hamstring injury was diagnosed and located on MR imaging by identifying high signal intensity within the muscle on T2-weighted images. RESULTS: We found that 10 athletes had injuries of a single muscle with six injuries of the biceps femoris, three of the semitendinosus, and one of the semimembranosus. In an additional five athletes, we found primary injuries of the biceps femoris and secondary injuries of the semitendinosus. The injuries occurred in diverse locations within the muscles including five injuries at the proximal musculotendinous junction, two at the distal musculotendinous junction, four within the proximal half of the muscle belly, and four in the distal half. All eight intramuscular injuries were located at the musculotendinous junction within the muscle. CONCLUSION: The biceps femoris is the most commonly injured hamstring muscle and the semitendinosus is the second most commonly injured. Although hamstring injuries often involve one muscle injured proximally, multiple muscles were involved in 33% of athletes (5/15) and the injuries were distal in 40% of athletes (6/15). All intramuscular injuries occurred at the musculotendinous junction, either at the ends of the muscle or within the muscle belly.

Self-esteem and coping responses of athletes with acute versus chronic injuries.

Self-esteem and coping strategies have been important factors in athletes' response to injury and subsequent rehabilitation. Specifically, athletic injury has been negatively associated with self-esteem, while certain coping strategies may enhance adherence to rehabilitation (1, 4). Little is known, however, concerning the effect of acute (sudden specific event) versus chronic injury (repetitive injury over a prolonged period of time) on self-esteem and coping strategies. The Rosenberg Self-esteem Inventory (3), selected subscales of the Ways of Coping Questionnaire (2), and a demographic questionnaire were administered. The subscales of Ways of Coping Questionnaire employed were Seeking Social Support, Accepting Responsibility for the injury, and Escape Avoidance of the injury. To assess the influence of acute versus chronic injury status, effect sizes (ES) were calculated. Although no difference was found for Accepting Responsibility, chronically injured athletes scored higher on Escape/Avoidance (M = 2.4 vs 1.9, SD = 1.2 vs .6, ES = .52) and lower on Seeking Social Support (M = 2.5 vs 2.8, SD = .6 vs .4, ES = .47) than athletes with acute injuries. Those with chronic injuries also second more negatively on self-esteem (M = 6.2 vs 4.4, SD = 1.2 vs 1.2, ES = 1.30) than acutely injured athletes. These preliminary results suggest the type of injury may differentially affect self-esteem and coping behavior. As self-esteem is theorized to be relatively stable construct, it is perhaps not surprising that chronic injuries have a greater effect than acute injuries. Chronically injured athletes also sought social support less and engaged in more escape/avoidance behavior, suggesting that they cope with injury differently than those with acute injuries.

Current concepts in the rehabilitation of the athletic shoulder.

The rehabilitative process of the overhead athlete represents a significant challenge to the clinician. Overhead athletes (thrower, tennis player, swimmer) repetitively subject their shoulder joints to high microtraumatic stresses that, due to the accumulative effects, may lead to a variety of shoulder injuries. This type of athletic patient exhibits uniquely specific physical characteristics, such as hypermobility of the anterior shoulder capsule, excessive external rotation, hypomobility of the posterior capsule, limited internal rotation, and generalized ligamentous laxity of the glenohumeral joint. However, the overhead athlete must exhibit functional stability for pain-free sports participation. Functional stability is accomplished through the proficient balance of static (passive) and dynamic (active) stabilizers. During the rehabilitation process, various concepts, such as neuromuscular control, proprioception, force couple efficiency, plyometrics, eccentrics, and scapular stability, can enhance dynamic functional stability for the overhead athlete. The evaluation and treatment of the shoulder patient is in perpetual change, and the purpose of this paper is to discuss several current concepts in the rehabilitative treatment of the athletic shoulder patient.

Measures of functional limitation as predictors of disablement in athletes with acute ankle sprains.

STUDY DESIGN: Prospective multivariate design. OBJECTIVES: To determine the usefulness of activity scores, self-reported athletic ability, and selected measures of physical impairment as predictors of disability duration in athletes with ankle inversion sprains. BACKGROUND: Although several measures of physical impairment and functional limitation are used to assess the consequences of injury following ankle sprain, researchers have yet to establish which measures provide the most accurate predictions of disability duration. METHODS AND MEASURES: Physical impairment, activity limitation, and disability duration were measured in 21 athletes (13 men and 8 women; mean age = 20.3 +/- 1.7 years) with acute ankle sprains. Sagittal plane ankle range of motion and volumetric displacement were used as impairment indicators. Weight-bearing activity scores (task completion count) and self-reported athletic ability (visual analog scale) were used to represent functional limitation. Elapsed time from injury to return to full athletic participation was used as the criterion measure of disability duration. RESULTS: The impairment measures accounted for approximately one-third of the variance in disability duration (R2 = 0.342). Adding the activity limitation measures to the regression model improved predictions of disability duration (R2 = 0.670; stepwise R2 change = 0.328). The measures of activity limitation alone, however, accounted for approximately 67% (R2 = 0.665) of the total variance in the number of days lost due to injury. CONCLUSION: Measures of activity limitation were the strongest predictors of elapsed time from injury to return to full athletic participation.

Effects of athletic taping of the fetlock on distal limb mechanics.

REASONS FOR PERFORMING STUDY: Athletic taping is used frequently by human athletes to stabilise, maintain or strengthen soft tissue structures, but empirical evidence supporting any changes in equine kinematics is lacking. OBJECTIVES: To assess the effects of athletic taping of the fetlock applied by an experienced athletic trainer on forelimb mechanics in healthy horses. HYPOTHESES: That athletic taping of the distal forelimb reduces 1) hyperextension of the fetlock joint during stance, 2) flexion of the fetlock joint during swing and 3) ground reaction forces during stance. METHODS: Ground reaction force and kinematic data were obtained for 6 healthy horses trotting at 3 m/sec for 4 sequential conditions (baseline, untaped; pre-exercise, taped; post exercise, taped post 30 mins trotting exercise; transfer, 4 h after tape removal). Data were analysed using 2-way mixed ANOVAs (condition; joint). RESULTS: A statistically significant interaction was identified for the fetlock during the swing phase (mean +/- s.d. peak flexion at baseline 157 +/- 4 degrees, reduced with taping to 172 +/- 4 degrees; P<0.05) compared with no differences across conditions for the other joints. Peak vertical force reduced significantly (P<0.05) with taping. CONCLUSIONS: Athletic taping of the fetlock does not alter the kinematics of the forelimb during stance, but does limit flexion of the fetlock during the swing phase. The decreased peak vertical force may be due to an increased proprioceptive effect. POTENTIAL RELEVANCE: Reduced peak vertical forces may be of benefit in preventing or reducing injury. Further investigation remains necessary before it can be concluded that taping should be applied for tendinous or ligamentous rehabilitation in equine patients.

Bone density of élite female athletes with stress fractures.

To investigate whether stress fractures occurring in élite female athletes are related to reductions in bone mineral density (BMD), we measured BMD in nine athletes with such fractures and nine athletes without fractures who were matched for age, weight, height and sport. BMD was measured in three regions: upper limbs (distal radius), axial skeleton (lumbar spine) and lower limbs (femoral neck) by photon absorptiometry. The number of menses per year was significantly less (P less than 0.04) and the age of menarche was significantly delayed (mean +/- SD; 16.1 +/- 0.4 v. 14.4 +/- 1.5 years, P less than 0.02) in the fracture group compared with the non-fracture group. There was no significant difference in BMD between the two groups at any of the measurement sites. Moreover although the fractures occurred mainly in lower limb bones, at sites characterised by predominantly cortical bone, all athletes had femoral neck BMD values within the 95% confidence limits for normal non-athletic women. We conclude that stress fractures in élite female athletes are largely independent of BMD.

Meniscal tears in the athlete. Operative and nonoperative management.

There are many factors to consider when treating an active individual with a known or suspected meniscal tear. The athlete with a meniscal tear sometimes can return to competition, temporarily delaying surgery until after the season. If an athlete remains symptomatic and is unable to return, however, then arthroscopic surgery generally is effective to allow the athlete to resume participation. The decision of meniscal repair versus excision must be carefully thought out and discussed with the athlete before surgery. Either treatment can allow the athlete to return to their sport. It is controversial whether or not an athlete should be allowed early return to play after meniscal repair. Further prospective randomized studies would provide useful information in deciding which type of treatment and which type of rehabilitation is best suited for the active individual.

The ocular and visual characteristics of an athletic population.

BACKGROUND: Nine hundred and thirty-nine athletes of various ages and from varying levels of competition were part of a sports vision epidemiology project conducted by the Sports Vision Service at the Illinois Eye Institute, Chicago, Illinois. METHODS: Data were collected from sports vision screenings conducted from 1992 to 1995. The population consisted of participants in the 1994 and 1995 AAU Junior Olympic Games, members of the DePaul, Elmhurst, Illinois and College of DuPage athletic departments, and members of two local high school basketball programs, DuSable and Dunbar. The data collected were analyzed to determine the use of eye care services and the visual characteristics present in these elite athletic populations. RESULTS: Analysis of the data showed that athletes competing at high levels of competition do have visual problems. Twenty five percent of our population had never had a complete eye examination, 29% had visual symptoms, and 28% had less than 20/25 acuity through their habitual sports prescription. CONCLUSIONS: The results of this study imply that the athletic populations at all levels are in need of eye care services. Protective eyewear is not often used in this athletic population. Comparing the results found in our population to other reported results in the general population indicate similar rates of refractive error.

[Cardiovascular diseases as a cause of sudden death in athletes].

Cardiac arrhythmias are the reason of the most sudden deaths in athletes. The annual risk of sudden death at athletes is between 5 to 10 per one million. Benign arrhythmia including bradyarrhythmias, atrial and ventricular premature contractions are common in the athletes. Supraventricular arrhythmias such as atrial fibrillation, nodal reciprocal entrant tachycardia and Wolff-Parkinson-White syndrome are less common. Perhaps the rarest and the most dangerous arrhythmias are ventricular arrhythmias, among them arrhythmias secondary to hypertrophic cardiomyopathy, arrhythmogenic right ventricular dysplasia, long QT syndrome, and anomalous origin of coronary arteries. Asymptomatic bradyarrhythmias (if the heart rate in bradyarrhythmia appropriate increases with exercise), supraventricularis tachycardias, and atrial premature contractions without structural heart disease are not the contraindication to sports Athletes with premature ventricular contraction, nonsustained ventricular tachycardia and non structural heart disease are without athletic restrictions as long as the arrhythmias do not worsen and they not cause dyspnea or presyncope during exertion. Frequent or multiform premature ventricular contraction or sustained ventricular tachycardia indicate a higher risk, and all participation in athletic should be restricted.

Cervical spine injuries in the pediatric and adolescent athlete.

Injuries of the cervical spine in the pediatric and adolescent athlete are less common than other musculoskeletal injuries. Although many of these injuries are relatively minor, serious and potentially unstable or progressive spinal injury must be excluded. Important anatomic differences between the child younger than 10 years and older children and adolescents influence the types of injuries sustained and make assessment of the child's cervical spine sometimes difficult for practitioners accustomed to treating adolescent and adult athletes. Stable soft-tissue injuries of the cervical spine are the most common injuries that occur in all athletes. These injuries are responsive to symptomatic treatment and aggressive rehabilitation. Stingers are injuries of the brachial plexus and upper cervical roots that result from stretching or compressive forces associated with collision sports. Rapid return of sensory and motor dysfunction of a single upper extremity characterizes this entity; long-term disability is rare. Cervical cord neurapraxia (CCN) with transient quadriplegia is most commonly seen in football players. Most athletes fully recover. Cervical canal stenosis as defined by a Pavlov/Torg ratio of less than or equal to 0.8 is predictive of recurrent CCN. Young athletes sustain CCN secondary to hypermobility of the immature cervical spine. Return to play after these injuries is controversial. The athlete with Down syndrome and potential cervical hypermobility requires a careful cervical and neurologic evaluation prior to clearance for participation in sports.

Development of content-valid technical skill assessment instruments for athletic taping skills.

BACKGROUND AND PURPOSE: The content validity of technical skill assessment instruments (TSAI) for the skills of athletic taping has not been reported. The purpose of this paper is to outline and present the process of content validation for nine TSAIs for athletic taping. Local and national validators were selected from Canadian Athletic Therapists' Association (CATA)-accredited athletic therapy (AT) programs to serve as content validators. METHODS: The process of content validation began with the creation of a detailed task analysis via mail and simple validation by local validators. Subsequently, the detailed task analysis was committee validated by a group of 10 validators from across Canada. Validators judged the importance and difficulty of each item, and a face-to-face committee-validator meeting established consensus on the majority of checklist items. Through a modified Ebel procedure, frequency distribution was used in the formation of the final TSAIs. RESULTS: Initial consensus for pre-taping assessment and technical skill performance items was low. Upon committee discussion and lack of agreement, the decision to remove pretaping assessment items was made. Initial results of importance and difficulty for athletic taping technical skills were low prior to the committee meeting. Results of importance and difficulty improved substantially following the face-to-face committee-validators meeting. Consensus on fail points improved from initial to final committee validation. CONCLUSION: The process of simple and committee validation can be seen as effective methods to establish the content validity of instruments used for the evaluation of athletic taping.

Rotator cuff injuries in the contact athlete.

Rotator cuff injuries in contact athletes are typically a result of a different mechanism than that seen with older patients or overhead athletes. This unique mechanism along with the extreme demands of these athletes presents special challenges to the surgeon. Special consideration should be given to in-season rehabilitation to allow the athlete to continue to compete if possible. When this is not possible, or for the out-of-season athlete with a rotator cuff injury requiring surgery, special consideration must be given to obtaining the strongest repair possible. The goal in all aspects of treatment is returning the athlete to full participation safely while minimizing recurrent injury or disability during the recovery process.

Radiologic abnormalities of the thoraco-lumbar spine in athletes.

A radiologic study of the thoraco-lumbar spine was performed in 143 (117 male and 26 female) athletes (wrestlers, gymnasts, soccer players and tennis players), aged 14 to 25 years and 30 male non-athletes, aged 19 to 25 years. Film interpretation was made after mixing the films from all groups and without knowledge of the individual's identity. Various types of radiologic abnormalities occurred in both athletes and non-athletes but were more common among athletes, especially male gymnasts and wrestlers. Abnormalities of the vertebral ring apophysis occurred exclusively in athletes. Combinations of different types of abnormalities were most common in male gymnasts and wrestlers.

Upper extremity arterial injury in athletes.

Between 1983 and 1986, 23 athletes were evaluated for arm and hand complaints. Eleven players had symptoms of thoracic outlet compression. Severe arm fatigue (eight patients) and finger ischemia (three patients) were the presenting symptoms. In the remaining 12 athletes, symptoms of hand ischemia were predominant. Noninvasive testing with Doppler ultrasonography and duplex scanning (positional testing and finger systolic pressure recording) and cold immersion were used to aid in diagnosis. In the 11 athletes with thoracic outlet compression, arteriography confirmed the finding with compression of the subclavian artery in five, the axillary artery in one, both subclavian and axillary arteries in two, posterior humeral circumflex artery in one, and subclavian aneurysm in two. Compression of the suprascapular artery was identified in four, the subscapular artery in two, and the posterior humeral circumflex artery in one. Thrombosis of a first baseman's ulnar artery and occlusion of the palmar arch in a frisbee player were documented by arteriography. Decompression of the thoracic outlet consisted of anterior scalenectomy in five, pectoralis minor muscle division in one, and resection of both muscles in two. Removal of cervical rib with interposed vein graft was performed in the two players with arterial aneurysm. Hand ischemia in the remaining athletes was treated conservatively with Dextran-heparin infusion for acute ischemia. Repeat noninvasive study of all players demonstrated absence of compression in their playing position, and all have resumed their playing careers. Hand ischemia in athletes can be evaluated noninvasively and treated conservatively. Resection of hypertrophied muscles to decompress the thoracic outlet together with release of branch artery compression in selected athletes promotes perfusion to arm and shoulder muscles and helps to avoid the catastrophic complication of repetitive trauma leading to sudden arterial thrombosis.

Biomechanical aspects of lumbar spine injuries in athletes: a review.

One of the areas of the body which is very often injured by athletes is the lower lack, or the lumbar area of the spine. This problem is of some concern to physical educators, athletic therapists, coaches, athletes, and physicians. The type of injury which occurs in the lumbar spine is dependent on the direction, magnitude, and the point of application of the forces to the spine. This part of the body is susceptible to injury due to the large forces which must be supported, which include the body weight and any external weights, as well as the forces due to very high accelerations of the body parts. Since the lumbar spine is the only connecting column between the upper and lower parts of the body, all the forces must be transmitted via these structures. There are two general techniques of calculating the forces on the lumbar spinal structures, a static approach and a dynamic approach. The static approach may be useful to calculate compression and shear forces on the spine in stationary positions as may be seen in weightlifting. However, the dynamics approach should be used to calculate the effects of the various weights and inertial forces on spinal structures. The most common types of lower back injuries found in athletes were: muscle strains, ligament sprains, lumbar vertebral fractures, disc injuries, and neural arch fractures. The most common serious athletic injury to the lower back was found to be neural arch fractures at the pars interarticularis, or the isthmus between the superior and inferior articular processes. These fractures are known as spondylolysis, or defect in the pars interarticularis of one side of the vertebrae; and spondylolisthesis, a bilateral defect in the pars interarticularis, often accompanied by forward displacement of the vertebral body. The sports in which lower back injuries commonly occurred were also examined, and it was determined that gymnastics, weightlifting and football were the sports in which the lower back is at greatest risk. In order to help to reduce, the high incidence of injuries to this area of the body, athletes should attempt to increase the strength of the abdominal muscles, and to maximize the flexibility of the lower back.

Athletic preparticipation examinations for adolescents. Report of the Board of Trustees. Group on Science and Technology, American Medical Association.

In response to a request from the House of Delegates to study the value of the preparticipation athletic examination for adolescents, the American Medical Association Board of Trustees prepared a report reviewing the current health status of adolescent athletes and the efficacy of trying to identify which athletes are at risk for injury and sudden death. It found that between 22% and 39% of athletes sustain an injury that results in their not completing a practice or game or causes them to miss a subsequent practice or game. The existing state of information suggests that the preparticipation athletic examination is helpful in identifying adolescents at risk for orthopedic injury. The usefulness of the examination to identify adolescents at risk for sudden cardiac death or who have previously undiagnosed medical disorders is not substantiated by the research literature. The identification of orthopedic problems is maximized by the station approach. The guidelines developed in 1988 by the American Academy of Pediatrics provide the most current source on which conditions disqualify athletes from specific sports. Special care must be taken, however, to ensure that adolescents are not excluded unnecessarily from participation.

[Stress reactions and stress fractures in the high performance athlete. Causes, diagnosis and therapy].

From 1987 until July 1991 70 athletes with stress reactions or stress fractures were treated in the orthopaedic department of the Hannover Medical School. The average age of the 42 male and 28 female athletes was 22.6 years. The number of athletes involved in track and field sports was 29 (41.4%), in gymnastics 9 (12.9%) and in soccer 5 (7.1%). The most common bone injured was the tibia in 29 (41.4%), followed by the tarsal navicular in 21 (30.0%), the midfoot in 17 (24.3%) and the fibula in 4 (5.7%) athletes. In three cases double stress fractures were found in adjacent locations; in one case a stress fracture of the opposite navicular occurred after the initial tarsal navicular stress fracture had healed, and in another case the tarsal navicular was found to be fractured again. Thirty-seven percent of the athletes claimed sudden increase in training intensity was the cause; 33% felt that the increased sprinting and jump activities were the reason for their complaints. In some athletes pain started after an ankle sprain. Standard diagnostic procedure consisted in X-rays in two planes and three-phase bone scanning. In tarsal navicular or tibial locations additional tomograms were performed. MRI and CT scans were reserved for unclear findings and to exclude the possibility of a tumorous or inflammatory process. A new grading system was introduced that covers all forms of stress reactions from periostitis to pseudarthrosis. Clinical symptoms, sport disabilities, radiological and bone scan findings were graded from A to D. Using a modified Wilson classification, all radiologically recognizable stress reactions could be classified.(ABSTRACT TRUNCATED AT 250 WORDS)
