ABSTRACT

ABSTRACT: A 72-year-old male presented for evaluation of a 2-wk history left buttock pain that began while playing pickleball. He sustained a left inversion ankle sprain while in a squatted position and landed on his left buttock. Four days after his injury, he developed extensive bruising involving his lower back, buttock, and left thigh. On examination, he had tenderness to palpation at the left side of the sacrum and in the region of the deep external rotators. Left hip range of motion was full in extension but limited to 90° of flexion, which reproduced left-sided buttock pain. External rotation provoked pain, but internal rotation was full and pain free. MRI of the pelvis demonstrated a grade 2 partial thickness tear of the left gluteus maximus muscle at its distal myotendinous junction with associated retraction and intramuscular hematoma. He was managed with compression with biking shorts, icing, acetaminophen, and physical therapy. He returned to pickleball approximately 4 wk after his injury, and at his 4-wk follow-up, he reported 99% improvement in his symptoms with the only remaining complaint being minimal discomfort with gluteal stretching.

ABSTRACT

Concussion is a mild traumatic brain injury causing temporary neurologic dysfunction. Symptoms following concussion are variable and generally are expected to resolve within about 1 month, but some patients experience persistent and prolonged symptoms. An early return to safe, symptom-limited activity is now favored, using targeted rehabilitation and treatments. Accommodations may be needed to facilitate return-to-school and work following concussion. Athletes should not be cleared for a full return to sport until they have recovered from a concussion and completed a return-to-play progression, in addition to returning to work/school fully.

ABSTRACT

ABSTRACT: While injuries to the abdominal oblique muscles near their origin at the lower ribs are commonly seen in sports that require explosive trunk rotational movements such as baseball and tennis, there are few reports in the literature of avulsion injuries to these muscles from their distal attachments at the iliac crest. We present the case of two collegiate male hockey players who suffered such injuries as a result of a direct impact mechanism while rotated at the waist. These injuries should be suspected when patients have significant pain in the lower abdominal region worsened by flexion and rotation of the trunk and can be accurately characterized by musculoskeletal ultrasound or MRI. With a conservative rehabilitation program focused on core, hip adductor, and hip flexor strengthening, our athletes were able to return to game participation within 6 wk of the initial injury.

ABSTRACT

Mild traumatic brain injury, such as concussion, was once considered self-resolving. However, over the past decade, increased understanding of the short- and long-term impact has led to new guidelines for active management. In this review, we summarise recent findings, covering diagnostic criteria, and management for early and persistent symptoms. Many of the postconcussive symptoms can be treated and an individualised approach from a biopsychosocial perspective is recommended. Overall, the new knowledge will significantly impact patient care and future research.

ABSTRACT

This article outlines the key points in the nonoperative treatment of an anterior cruciate ligament (ACL) injury. Initial evaluation and treatment of an acute knee injury, often performed by a physician with limited experience in the treatment of an ACL injury, follow the basic diagnostic workup that lead to the diagnosis. The principles of rehabilitation after ACL injury have changed from time based to criteria based, and the different phases based on physical criteria are described.

ABSTRACT

The physical demands of sports can place patients at elevated risk of use-related pathologies, including thoracic outlet syndrome (TOS). Overhead athletes in particular (eg, baseball and football players, swimmers, divers, and weightlifters) often subject their subclavian vessels and brachial plexuses to repetitive trauma, resulting in venous effort thrombosis, arterial occlusions, brachial plexopathy, and more. This patient population is at higher risk for Paget-Schroetter syndrome, or effort thrombosis, although neurogenic TOS (nTOS) is still the predominant form of the disease among all groups. First-rib resection is almost always recommended for vascular TOS in a young, active population, although a surgical benefit for patients with nTOS is less clear. Practitioners specializing in upper extremity disorders should take care to differentiate TOS from other repetitive use-related disorders, including shoulder orthopedic injuries and nerve entrapments at other areas of the neck and arm, as TOS is usually a diagnosis of exclusion. For nTOS, physical therapy is a cornerstone of diagnosis, along with response to injections. Most patients first undergo some period of nonoperative management with intense physical therapy and training before proceeding with rib resection. It is particularly essential for ensuring that athletes can return to their baselines of flexibility, strength, and stamina in the upper extremity. Botulinum toxin and lidocaine injections in the anterior scalene muscle might predict which patients will likely benefit from first-rib resection. Athletes are usually satisfied with their decisions to undergo first-rib resection, although the risk of rare but potentially career- or life-threatening complications, such as brachial plexus injury or subclavian vessel injury, must be considered. Frequently, they are able to return to the same or a higher level of play after full recovery.

ABSTRACT

A concussion is the mildest form of a mild traumatic brain injury (tbi) and resembles the most prevalent type of sports associated tbi. Diffuse axonal injuries, the main pathophysiological mechanism of concussion, leads to disruption of communication between different brain areas. The resulting clinical symptoms may relate to several clinical domains (cognition, fatigue, anxiety disorders, headaches/migraines or vestibulo-ocular problems), all of which need to be assessed in a clinical screening during an evaluation for possible concussion. Appropriate and consensus-based protocols to conduct clinical exams are provided by the Concussion in Sport Group (Sport Concussion Assessment Tool (SCAT), Sport Concussion Office Assessment Tool (SCOAT)) and should be used in the most up-to-date version. Therapeutically, slowly and incrementally increasing sub symptomatic activation consisting of daily routine activities, aerobic and cognitive exercises should be introduced early after the trauma. Education about concussion should be geared towards target audiences and will then greatly contribute to adherence and acceptance of medical management.

ABSTRACT

AIM: Address deficiencies in access to sports sideline medical care by using a Concussion Check Protocol (CCP) for non-medically-trained people. METHOD: A prospective observational cohort study was undertaken on a single amateur female club-based soccer team over two consecutive years in New Zealand utilising a non-medically trained support person termed a Safety officer. CCP is an extension of the King-Devick test with features such as warning signs and symptoms of concussion built into the application. All players suspected of having a potential concussive injury were tested on the match sideline. RESULTS: The study overall incidence of match-related concussions was 20.8 (95% CI: 11.8 to 36.6) per 1000 match-hrs, with mean missed-match duration of 31 (95% CI: 27.9 to 34.1) days. Twelve players over the study had a significantly slower post-injury KD (49.9 [44.3 to 64.1]s; χ2(1) = 11.0; p = 0.0009; z = -2.9; p = 0.0033; d = 0.30) and/or reported symptoms, compared with their own baseline (47.2 [44.3 to 64.1]s). CCP had an overall sensitivity of 100% (95% CI: 73.5% to 100.0%), specificity of 100% (95% CI: 69.2% to 100.0%) and positive predictive value (PPV) of 100% (84.6% to 100.0%). CONCLUSION: Sideline use of CCP was undertaken successfully by non-medically trained people and provided a reliable platform for concussion identification.

ABSTRACT

OBJECTIVES: To investigate if the sport concussion assessment tool version 5 (SCAT5) could be suitable for application to Para athletes with a visual impairment, a spinal cord injury, or a limb deficiency. METHODS: A 16-member expert panel performed a Delphi technique protocol. The first round encompassed an open-ended questionnaire, with round 2 onwards being composed of a series of closed-ended statements requiring each expert's opinion using a five-point Likert scale. A predetermined threshold of 66% was used to decide whether agreement had been reached by the panel. RESULTS: The Delphi study resulted in a four-round process. After round 1, 92 initial statements were constructed with 91 statements obtaining the targeted level of agreement by round 4. The expert panellist completion rate of the full four-round process was 94%. In the case of athletes with a suspected concussion with either limb deficiencies or spinal cord injuries, the panel agreed that a baseline assessment would be needed on record is ideal before a modified SCAT5 assessment. With respect to visual impairments, it was conceded that some tests were either difficult, infeasible or should be omitted entirely depending on the type of visual impairment. CONCLUSION: It is proposed that the SCAT5 could be conducted on athletes with limb deficiencies or spinal cord injuries with some minor modifications and by establishing a baseline assessment to form a comparison. However, it cannot be recommended for athletes with visual impairment in its current form. Further research is needed to determine how potential concussions could be more effectively evaluated in athletes with different impairments.

ABSTRACT

BACKGROUND: Qualitative movement screening tools provide a practical method of assessing mechanical patterns associated with potential injury development. Biomechanics play a role in hamstring strain injury and are recommended as a consideration within injury screening and rehabilitation programs. However, no methods are available for the in-field assessment of sprint running mechanics associated with hamstring strain injuries. PURPOSE: To investigate the intra- and interrater reliability of a novel screening tool assessing in-field sprint running mechanics titled the Sprint Mechanics Assessment Score (S-MAS) and present normative S-MAS data to facilitate the interpretation of performance standards for future assessment uses. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 3. METHODS: Maximal sprint running trials (35 m) were recorded from 136 elite soccer players using a slow-motion camera. All videos were scored using the S-MAS by a single assessor. Videos from 36 players (18 men and 18 women) were rated by 2 independent assessors blinded to each other's results to establish interrater reliability. One assessor scored all videos in a randomized order 1 week later to establish intrarater reliability. Intraclass correlation coefficients (ICCs) based on single measures using a 2-way mixed-effects model, with absolute agreement with 95% CI and kappa coefficients with percentage agreements, were used to assess the reliability of the overall score and individual score items, respectively. T-scores were calculated from the means and standard deviations of the male and female groups to present normative data values. The Mann-Whitney U test and the Wilcoxon signed-rank test were used to assess between-sex differences and between-limb differences, respectively. RESULTS: The S-MAS showed good intrarater (ICC, 0.828 [95% CI, 0.688-0.908]) and interrater (ICC, 0.799 [95% CI, 0.642-0.892]) reliability, with a standard error of measurement of 1 point. Kappa coefficients for individual score items demonstrated moderate to substantial intra- and interrater agreement for most parameters, with percentage agreements ranging from 75% to 88.8% for intrarater and 66.6% to 88.8% for interrater reliability. No significant sex differences were observed for overall scores, with mean values of 4.2 and 3.8 for men and women, respectively (P = .27). CONCLUSION: The S-MAS is a new tool developed for assessing sprint running mechanics associated with lower limb injuries in male and female soccer players. The reliable and easy-to-use nature of the S-MAS means that this method can be integrated into practice, potentially aiding future injury screening and research looking to identify athletes who may demonstrate mechanical patterns potentially associated with hamstring strain injuries.

ABSTRACT

Peripheral nerve injuries in athletes affect the upper limb more commonly than the lower limb. Common mechanisms include compression, traction, laceration, and ischemia. Specific sports can have unique mechanisms of injury and are more likely to be associated with certain neuropathies. Familiarity with these sport-specific variables and recognition of the common presentations of upper limb neuropathic syndromes are important in assessing an athlete with a suspected peripheral nerve injury. Evaluation may require imaging modalities and/or electrodiagnostic testing to confirm a nerve injury. In some cases, diagnostic injections may be needed to differentiate neuropathic versus musculoskeletal etiology. Early and accurate diagnosis is essential for treatment/management and increases the likelihood of a safe return-to-sport and avoidance of long-term functional consequences. Most nerve injuries can be treated conservatively, however, severe or persistent cases may require surgical intervention. This monograph reviews key diagnostic, management, and preventative strategies for sports-related peripheral nerve injuries involving the upper limb.

ABSTRACT

OBJECTIVE: Evaluate the independent effect of age on baseline neurocognitive performance. STUDY DESIGN: Baseline ImPACT scores from tests taken by 7454 athletes aged 12-22 from 2009 to 2019 were split into three age cohorts: 12-14 years (3244), 15-17 years (3732), and 18-22 years (477). Linear regression analyses were used to evaluate the effect of age on ImPACT composite scores while controlling for demographic differences, medication-use, and symptom burden. Significance values have been set at p < 0.05. RESULTS: Linear regression analyses demonstrated that increased age does not significantly affect symptom score (ß = 0.06, p = 0.54) but does improve impulse control (ß = -0.45, p < 0.0001), verbal memory (ß = 0.23, p = 0.03), visualmotor (ß = 0.77, p < 0.0001), and reaction time (ß = -0.008, p < 0.0001) scores.  However, age did not have an effect on visual memory scores (ß = -0.25, p = 0.07). CONCLUSIONS: Age was shown to be an independent modifier of impulse control, verbal memory, visual motor, and reaction time scores but not visual memory or symptom scores.  This underscores the previous literature showing developmental differences as age increases among the adolescent athlete population.  This data also indicates the need for repeat neurocognitive baseline testing every other year as baseline scoring is likely to change as athletes become older.

ABSTRACT

OBJECTIVE: To evaluate the feasibility of an exercise tolerance assessment and intervention added to the Progressive Return to Activity Clinical Recommendations (PRA-CR) in acutely concussed service members (SMs). METHODS: This non-randomized, pilot trial was performed at one center. SMs in the experimental group (ERG) performed the Buffalo Concussion March-in-place Test (BCMT) at every clinic visit and were prescribed at least 20 minutes/day of targeted exercise in addition to PRA-CR. Data for the control group (SCG) were extracted from the same clinic immediately prior to ERG. SMs in both groups were assessed by the same clinician to determine return-to-duty. RESULTS: BCMT identified concussion-related exercise intolerance in 100% (n = 14) at screening visit (mean 3.4 days after injury) and in 0% (n = 7) who had recovered. No adverse effects were associated with BCMT. The estimated recovery time for ERG who performed the exercise intervention (n = 12) was 17.0 (12.8, 21.2) days and for SCG (n = 15) was 23.7 (19.9, 27.5) days (p = 0.039). CONCLUSION: Assessment of exercise tolerance was feasible and could be incorporated into the PRA-CR. Future definitive, randomized controlled trials should be performed to assess the effectiveness of exercise reset program for SMs after concussion.

ABSTRACT

BACKGROUND: Pre-existing mental health diagnoses may contribute to greater emotional symptom burden and prolonged recovery after concussion. HYPOTHESIS: Youth with pre-existing mental health diagnoses will have greater emotional symptom burden, greater risk for delayed return to exercise, and more prolonged recovery from concussion than those without those diagnoses. STUDY DESIGN: Prospective cohort. LEVEL OF EVIDENCE: Level 3. METHODS: A prospective registry of youth concussion was examined for differences in emotional symptom burden after injury to develop a predictive risk model for prolonged recovery. The impact of individual and total number of pre-existing mental health diagnoses (0, 1, 2, and 3+) was assessed, and multivariable logistic regression was performed to identify factors associated with prolonged recovery. RESULTS: Among a cohort of 3105 youth with concussion, those with a history of mental health diagnoses, in a dose-response fashion, had greater postinjury emotional symptom burden (7 emotional symptoms vs 4; P < 0.01), visio-vestibular dysfunction (65% abnormal vs 56% abnormal; P < 0.01), later return to symptom-limited exercise (23 vs 21 days; P < 0.01), and overall longer concussion recovery (38 days, interquartile range [IQR] 18, 80) versus 25 days (IQR 13, 54; P < 0.01). Boys with prolonged recovery after concussion had greater emotional symptom burden than girls (5 emotional symptoms vs 3; P < 0.01). CONCLUSION: Pre-existing mental health diagnoses are associated with greater postinjury emotional symptom burden and longer concussion recovery in a dose-response fashion. Visiovestibular deficits and delayed return to exercise are also associated with pre-existing mental health diagnoses and prolonged recovery. Boys with prolonged recovery from concussion experience greater emotional symptom burden than girls. CLINICAL RELEVANCE: Addressing pre-existing mental health diagnoses is essential to concussion management. Boys with prolonged recovery from concussion may particularly benefit from interventions to address their higher emotional symptom burden. Interventions, including a home visio-vestibular exercise program and symptom-limited exercise, may contribute to improving time to concussion recovery.

ABSTRACT

Objective: To assess student-athletes' knowledge and attitudes towards sport-related concussions and to investigate concussion history and reporting behaviours. METHODS: The cross-sectional, survey-based study was conducted from September 2020 to June 2021 after approval from the research ethics committee of Universiti Malaya, Malaysia, and comprised student-athletes of either gender aged 18 years or above at various universities across Pakistan and who played contact or collision sports for their universities. Data was collected using the Urdu version of the Rosenbaum Concussion Knowledge and Attitudes Survey-Student Version. Data was also gathered about the participants' self-reported exposure to formal concussion education, previous sport-related concussion history, and reporting behaviours, where applicable. Data was analysed using SPSS 23. RESULTS: Of the 369 participants, 224(60.7%) were males and 145(39.3%) were females. The overall mean age was 19.95±1.75 years. Among the participants, 327(88.6%) had not received formal concussion education. The mean knowledge score was 12.76±2.73 out of a possible 25 points, and the mean attitude score was 38.63±10.30 out of 75 points. Knowledge had a weak positive correlation with attitude towards sport-related concussions SRC (p<0.05). Females displayed better attitudes towards sport-related concussions than their male counterparts (p<0.05). Overall, 126(34%) participants had experienced sport-related concussion symptoms following a blow to the head in the preceding 12 months, and 81(64.3%) of them had continued playing while being symptomatic. Conclusion: Pakistani university student-athletes lacked adequate concussion knowledge and held poor attitudes towards sport-related concussions.

ABSTRACT

CONTEXT: The Child Sport Concussion Assessment Tool, fifth edition (SCAT5), remains the consensus instrument for concussion evaluation in youth athletes. Both child and parent are recommended to complete the athlete background and symptom reporting. OBJECTIVE: To determine the level of agreement between child and parent medical history and symptom reporting and quantify their performance on the Child SCAT5 in male football athletes. DESIGN: Cross-sectional study. SETTING: National Collegiate Athletic Association Division I college football facility. PATIENTS OR OTHER PARTICIPANTS: A total of 157 youth male football athletes (age = 10.7 ± 1.3 years) participating in a university-sanctioned youth football camp and their parent or legal guardian. MAIN OUTCOME MEASURE(S): Youth athletes and their parent completed the athlete background (demographics, diagnosed medical history) and symptom evaluation (symptom items, total number of symptoms, and symptom severity score) of the Child SCAT5 and were instructed not to discuss reporting with each other during testing. Cronbach α tests were conducted to determine the internal consistency, and descriptive statistics determined the level of agreement between medical history, symptom reporting, and baseline performance. RESULTS: The internal consistency of the symptom items was high for both child (Cronbach α = 0.91) and parent (α = 0.92). Agreement on medical history ranged from 67% (learning disability or dyslexia) to 85% (attention-deficit/hyperactivity disorder), with 82% agreement on sustaining a previous concussion. Fourteen youth athletes reported having been hospitalized for a head injury, with zero matched parent confirmations. Individual symptom agreement ranged from 70.7% (gets distracted easily) to 94.9% (going to faint). Agreement was 35% on total number of symptoms and severity. Abnormal scoring ranged from 2% (going to faint) to 25% (headache) for child and 2% (double vision) to 28% (gets distracted easily) for parent reporting. CONCLUSIONS: Fair agreement was shown between children and their parent on medical history and self-reported symptoms on the Child SCAT5 at baseline. When available, child and parent reporting should be used for concussion assessment and clinical decision-making.

ABSTRACT

Although many outcome studies pertaining to sports-related concussion exist, female athletes with concussion remain an understudied group. We examined whether neurocognitive performance in adolescent females with sports-related concussion (SRC) is related to menstrual cycle-related hormone levels measured at one-week post-concussion, one-month post-concussion, or both. Thirty-eight female athletes, ages 14-18, were matched into two groups: SRC or healthy control. Self-reported symptom scores were higher among concussed females in the luteal phase, when progesterone levels are highest. Results suggest that progesterone levels may contribute to a heightened experience of symptoms during the acute phase of SRC, providing further evidence of a possible link between progesterone and symptom scores following concussion.

ABSTRACT

OBJECTIVE: As opposed to postconcussion physical activity, the potential influence of cognitive activity on concussion recovery is not well characterised. This study evaluated the intensity and duration of daily cognitive activity reported by adolescents following concussion and examined the associations between these daily cognitive activities and postconcussion symptom duration. METHODS: This study prospectively enrolled adolescents aged 11-17 years with a physician-confirmed concussion diagnosis within 72 hours of injury from the emergency department and affiliated concussion clinics. Participants were followed daily until symptom resolution or a maximum of 45 days postinjury to record their daily cognitive activity (intensity and duration) and postconcussion symptom scores. RESULTS: Participants (n=83) sustained their concussion mostly during sports (84%), had a mean age of 14.2 years, and were primarily male (65%) and white (72%). Participants reported an average of 191 (SD=148), 166 (SD=151) and 38 (SD=61) minutes of low-intensity, moderate-intensity and high-intensity daily cognitive activity postconcussion while still being symptomatic. Every 10 standardised minutes per hour increase in moderate-intensity or high-intensity cognitive activities postconcussion was associated with a 22% greater rate of symptom resolution (adjusted hazard ratio (aHR) 1.22, 95% CI 1.01 to 1.47). Additionally, each extra day's delay in returning to school postconcussion was associated with an 8% lower rate of symptom resolution (aHR 0.92, 95% CI 0.85 to 0.99). CONCLUSION: In adolescents with concussion, more moderate-high intensity cognitive activity is associated with faster symptom resolution, and a delayed return to school is associated with slower symptom resolution. However, these relationships may be bidirectional and do not necessarily imply causality. Randomised controlled trials are needed to determine if exposure to early cognitive activity can promote concussion recovery in adolescents.
