Several sports have published consensus statements on methods and reporting of epidemiological studies concerning injuries and illnesses with football (soccer) producing one of the first guidelines. This football-specific consensus statement was published in 2006 and required an update to align with scientific developments in the field. The International Olympic Committee (IOC) recently released a sports-generic consensus statement outlining methods for recording and reporting epidemiological data on injury and illness in sport and encouraged the development of sport-specific extensions.The Fédération Internationale de Football Association Medical Scientific Advisory Board established a panel of 16 football medicine and/or science experts, two players and one coach. With a foundation in the IOC consensus statement, the panel performed literature reviews on each included subtopic and performed two rounds of voting prior to and during a 2-day consensus meeting. The panel agreed on 40 of 75 pre-meeting and 21 of 44 meeting voting statements, respectively. The methodology and definitions presented in this comprehensive football-specific extension should ensure more consistent study designs, data collection procedures and use of nomenclature in future epidemiological studies of football injuries and illnesses regardless of setting. It should facilitate comparisons across studies and pooling of data.

ObjectiveTo determine the test–retest reliability of the Brain Injury Screening Tool (BIST), which was designed to support the initial assessment of mild traumatic brain injury (mTBI) across a variety of contexts, including primary and secondary care.DesignTest–retest design over a 2-week period.SettingCommunity based.ParticipantsSixty-eight adults (aged 18–58 years) who had not experienced an mTBI within the last 5 years and completed the BIST on two different occasions.MeasuresParticipants were invited to complete the 15-item BIST symptom scale and the Depression, Anxiety and Stress Scale (DASS-21) online at two time-points (baseline and 2 weeks later). To account for large variations in mood affecting symptom reporting, change scores on the subscales of the DASS-21 were calculated, and outliers were removed from the analysis.ResultsThe BIST total symptom score and subscale scores (physical-emotional, cognitive and vestibular) demonstrated moderate to good test–retest reliability with intraclass correlation coefficients ranging between 0.51 and 0.83. There were no meaningful differences between symptom reporting on the total scale or subscales of the BIST between time1 and time2 at the pConclusionThe BIST showed evidence of good stability of symptom reporting within a non-injured, community adult sample. This increases confidence that changes observed in symptom reporting in an injured sample are related to actual symptom change rather than measurement error and supports the use of the symptom scale to monitor recovery over time. Further research is needed to explore reliability of the BIST within those aged

Objectives To investigate the effectiveness of a futsal-specific warm-up to reduce injuries in amateur teams. Design Quasi-experimental. Setting Two futsal centres followed over one season using a specific report card. Participants 878 teams (Intervention group, n = 458; Control group, n = 420) of both genders and three age groups (U13, U17, adults). Intervention A futsal-specific warm-up consisting of cardiovascular exercises, dynamic stretches, and game-related skills. Main outcome measures The incidence rate and severity of all injuries, lower extremity (LE) injuries and contact injuries. A multivariate Poisson regression analysis was used to compare between-group rates. Results The rate of all injuries was lower in the intervention group (rate ratio (RR) = 0.72, 95% CI = 0.59 to 1.06), yet not significant. There was a significantly lower rate of contact injuries in the intervention group (RR = 0.68, 95% CI = 0.51 to 0.98). Subgroup analysis, based on the warm-up adherence of intervention teams (low, intermediate, high), showed a lower rate of all injuries (RR = 0.52, 95% CI = 0.29 to 0.97), and LE injuries (RR = 0.32, 95% CI = 0.14 to 0.81) in the high compared to low adherence group. Conclusion A futsal-specific warm-up can reduce the rate of contact injuries in amateur players. With high adherence the rate of all injuries and LE injuries may also reduce.

To assess the current state of knowledge around sport-related concussion (SRC) guidelines and management among primary care doctors in New Zealand.An online, self-administered, 21-item multi-choice questionnaire targeted at general practitioners and urgent care doctors in New Zealand was used. Main outcome measures were knowledge and management of patients with SRC through to return-to-sport.There were 230 total valid responses. Over half had no knowledge of the Consensus Statement on Concussion in Sport, and only 43% used the Sport Concussion Assessment Tool (SCAT) routinely. Fifty-eight percent would prefer to have a screening tool integrated into their patient management software. Most reported using appropriate management strategies for patients with concussion and recognised the potential benefit of relative cognitive and physical rest. There was low utilisation of referral pathways to allied health practitioners and specialist concussion services. Half (53%) felt confident in managing a patient with SRC and 46% felt comfortable managing return-to-sport.Primary care doctors have good knowledge of SRC but are not as confident managing return-to-sport. Further education opportunities were identified. Development of concussion tools adapted for use in primary care, integrated with patient management software and that support pathways to optimise patient recovery are recommended.

BackgroundTrigger finger (TF), a painful condition involving a finger flexor tendon, is a common problem with a prevalence of ~2-3% in the general population. However, the TF prevalence is higher among diabetic patients-ranges from 6.7% to 10%. We have analyzed the expression of the extracellular matrix, inflammation, and epigenetic related genes in diabetic and non-diabetes TF. We hypothesized that Diabetes condition induces alter the expression of epigenetic modification genes in diabetic patients and one of the underlying determinants for more prevalence of TF in diabetic patients.MethodTissues from the fingers of patients with symptomatic trigger fingers were collected. We had three groups: carpal tunnel syndrome (as a control), trigger finger, and diabetic trigger finger. A quantitative real-time polymerase chain reaction was performed. The gene expression of Extracellular matrix (ECM) components [COL-I, COL-II, COL-X, Aggrecan], DNA methyltransferases enzymes (DNMT1, DNMT3), growth factors (TGF-b, IGF), and Histone deacetylase enzymes (HDAC1, HDAC2) were evaluated in all groups.ResultsThe mRNA expression of COL-I, COL-II, Aggrecan was significantly higher in the pully A1 of diabetic patients (p= 0.0164, p=0.0351, p=0.0399, respectively) as compared to non-diabetic TF patients. Diabetes was associated with a significant increase in the DNMT3 expression compared to non-diabetic TF patients (p=0.0485). HDAC1 and HDAC2 gene expression were up-regulated in diabetic TF than non-diabetic TF.ConclusionThe chronic state of hyperglycemia induces epigenetic modification of gene expressions in trigger fingers. This seems to have a significant impact on the development, recurrence, and progression of trigger finger in diabetic patients.

To identify which aspects of initial clinical assessment for sport-related mild traumatic brain injury (SR-mTBI) predict whether an athlete achieves symptom resolution within 14 days of the injury. Retrospective cohort study using prospectively collected data. Clinical assessment data were collected from 568 patients diagnosed with SR-mTBI at a single medical clinic between February 2017 and December 2018. Demographic data, medical history, SCAT-5 testing, and physician notes were included in the data set. Data were processed and analysed to identify a shortlist of predictor variables to develop a logistic regression model to discriminate between SR-mTBI symptom resolution that occurred in ≤ 14-days or > 14-days. The data were randomly divided into model development and validation subsamples. The top 15 models were analysed to determine the predictor variables to be included in the final logistic regression model. The final model was then applied to the validation subsample. Half of the athlete participants in this study experienced > 14-day symptom resolution. The final logistic regression model included sex, symptom reporting at initial assessment and presentation with a physiological predominant symptom cluster. The model accounted for 0.90 and 0.85 of the area under the curve and predicted recovery trajectory with 81% and 76% accuracy for the training and validation subsamples, respectively. Being female, reporting a higher Positive Symptom Total at initial assessment, and being less likely to have a physiological predominant symptom cluster at initial assessment predicted > 14 versus ≤ 14-day SR-mTBI symptom resolution with a high level of accuracy.

Currently health care pathways (the combination and order of services that a patient receives to manage their injury) following a mild traumatic brain injury vary considerably. Some clinicians lack confidence in injury recognition, management and knowing when to refer. A clinical expert group developed the Brain Injury Screening Tool (BIST) to provide guidance on health care pathways based on clinical indicators of poor recovery. The tool aims to facilitate access to specialist services (if required) to improve longer term prognosis. The tool was developed using a three-step process including: 1) domain mapping; 2) item development and 3) item testing and review. An online retrospective survey of 114 adults (>16 years) who had experienced a mild brain injury in the past 10 years was used to determine the initial psychometric properties of the 15-item symptom scale of the BIST. Participants were randomised to complete the BIST and one of two existing symptom scales; the Rivermead Post-concussion Symptom Questionnaire (RPQ) or the Sports Concussion Assessment Test (SCAT-5) symptom scale to determine concurrent validity. Participant responses to the BIST symptom scale items were used to determine scale reliability using Cronbach’s alpha. A principal components analysis explored the underlying factor structure. Spearman’s correlation coefficients determined concurrent validity with the RPQ and SCAT-5 symptom scales. The 15 items were found to require a reading age of 6–8 years old using readability statistics. High concurrent validity was shown against the RPQ (r = 0.91) and SCAT-5 (r = 0.90). The BIST total symptom scale (α = 0.94) and the three factors identified demonstrated excellent internal consistency: physical/emotional (α = 0.90), cognitive (α = 0.92) and vestibular-ocular (α = 0.80). This study provides evidence to support the utility, internal consistency, factor structure and concurrent validity of the BIST. Further research is warranted to determine the utility of the BIST scoring criteria and responsiveness to change in patients.

Sports-related concussion (SRC) is a risk across all sports. New Zealand physiotherapists are more frequently in attendance at sporting events than medical doctors. The aim of this study was to determine the knowledge, attitudes, and behaviours of physiotherapists working with SRC, using a 35-item, multi-choice questionnaire. The survey was completed by 122 physiotherapists (response rate 10%). Physiotherapists were knowledgeable regarding SRC and showed positive attitudes towards correct management of the injury. Of the respondents, 98% recognised the key signs and symptoms of SRC, and 88% would refer to a medical practitioner for further assessment of SRC. Physiotherapists indicated a strong desire to be more involved in sideline management and testing, and would like to see a more multidisciplinary approach to return-to-play decision-making after SRC. Given that the knowledge, attitudes, and behaviours of New Zealand physiotherapists to SRC were very good, it is suggested that the processes in New Zealand be reviewed to enable physiotherapists to be more involved in the assessment and management of concussion.

Trigger finger is a common yet vastly understudied fibroproliferative hand pathology, severely affecting patients’ quality of life. Consistent trauma due to inadequate positioning within the afflicted finger’s tendon/pulley system leads to cellular dysregulation and eventual fibrosis. While the genetic characteristics of the fibrotic tissue in the trigger finger have been studied, the pathways that govern the initiation and propagation of fibrosis are still unknown. The complete gene expression profile of the trigger finger has never been explored. Our study has used the Nanostring nCounter gene expression assay to investigate the molecular signaling involved in trigger finger pathogenesis. We collected samples from patients undergoing trigger finger (n = 4) release surgery and compared the gene expression to carpal tunnel tissue (n = 4). Nanostring nCounter analysis identified 165 genes that were differentially regulated, 145 of these genes were upregulated, whereas 20 genes were downregulated. We found that several collagen genes were significantly upregulated, and a regulatory matrix metalloproteinase (MMP), MMP-3, was downregulated. Bioinformatic analysis revealed that several known signaling pathways were dysregulated, such as the TGF-β1 and Wnt signaling pathways. We also found several novel signaling pathways (e.g., PI3K, MAPK, JAK-STAT, and Notch) differentially regulated in trigger finger. The outcome of our study helps in understanding the molecular signaling pathway involved in the pathogenesis of the trigger finger.

To assess the attitudes of mountain bikers to the use of protective equipment and quantify the use of such equipment.This was a prospective cohort study using an online questionnaire, offered to bikers participating in a series of Enduro races. The attitudes towards various factors that might contribute to a rider's choice to use protective equipment were quantified based on their responses to the questions. The actual reported use of various types of protective equipment was the outcome measure. The correlations between the factors and actual use were analysed for statistical significance, to assess their relative importance.Equipment use was similar in racing and non-racing settings and could be increased. 55% had experienced an injury requiring a week or more off work. Perceptions of the benefits, costs, cues, comfort and potential injury severity proved to be well correlated with the choice to use equipment, while harm, danger and exposure to media influences did not.

BACKGROUND Anterior cruciate ligament injuries cause significant morbidity, and may be increasing in incidence as participation in high-risk sports increases. The aim of this study is to investigate the incidence of anterior cruciate ligament reconstruction (ACLR) surgery in New Zealand, and to analyse changes over time in demographic subgroups. METHOD Data were sourced from the Accident Compensation Corporation. Data relating to primary ACLRs performed from 2009 to 2016 were evaluated (n = 20 751). Baseline population estimates were obtained from national census data to calculate the incidence, and results were compared to previous data from 2000 to 2005 (n = 7375). RESULTS The annual incidence of ACLR for 2009-2016 was 58.2 per 100 000 person-years and was greater in males than in females (72.2 and 44.9, respectively). This represents a 58% increase when compared with the period 2000-2005 (36.9 per 100 000). The greatest increase was seen in females aged 15-19 years, with the incidence increasing by 120% in the last decade, compared with 53% in females aged 20-24 years. The percentage of injuries caused by sports changed from 65% over 2000-2005 to 76% over 2009-2016, with netball, rugby and football accounting for the highest number of injuries. CONCLUSION The incidence of ACLR procedures has increased markedly in New Zealand, and this increase was most pronounced in females aged 15-19 years. A greater proportion of procedures are now due to sport-related injuries.

This report describes a 21-year-old man, a semiprofessional football (soccer) player, with a navicular stress fracture. It highlights the difficulty in diagnosing the condition and the complications arising from inadequate management. The case discusses the optimal management of these stress fractures and the detrimental role of weight-bearing recovery. The diagnosis of navicular stress fractures is challenging, and a high index of suspicion is required. The available literature indicates that limited weightbearing is not an appropriate treatment for navicular stress injuries. Non-weight-bearing (NWB) cast immobilisation for 6–8 weeks appears to be the gold standard treatment; however, open reduction with internal fixation (ORIF) has similar success rates and an equal return-to-play time but should also be followed by a period of NWB. NWB cast immobilisation for 6 weeks remains a good second option at any time following failed limited weight-bearing activity.

This report presents a case of brachial neuritis following a subacromial corticosteroid injection. The patient developed an anterior interosseous neuropathy shortly after the injection, with no other trigger being identified. This neuropathy has unfortunately not shown any sign of recovery at 2 years. The authors propose that corticosteroid injection be added to the list of possible triggering events of brachial neuritis and highlight the frequent use of oral corticosteroids in its treatment. (1) The injection of local anaesthetic and corticosteroid should be considered as a potential trigger for brachial neuritis. (2) Brachial neuritis should be considered in the differential diagnosis for patients presenting with severe arm pain and weakness. (3) The nerves originating from the upper trunk of the brachial plexus are most commonly affected. (4) The anterior interosseous nerve is involved in one-third of cases.
