Surfing has rapidly grown in popularity as the sport made its debut at the Tokyo 2020 Olympic Games. Surfing injuries are becoming more relevant with the globalisation and increasing risks of the sport, but despite this, little is known about surfing injuries or prevention strategies in either the competitive or recreational surfer. Prior research demonstrates that surfers are injured at a frequency of 0.74–1.79 injuries per 1000 hours of surfing. We reviewed the literature for the incidence, anatomical distribution, type and underlying mechanism of acute and overuse injuries, and discuss current preventative measures. This review finds that skin injuries represent the highest proportion of total injuries. Acute injuries most frequently affect the head, neck and face, followed by the lower limbs. Being struck by one’s own board is the most common mechanism of injury. Non-contact acute ligament injuries have increased as surfing manoeuvres have become more acrobatic and overuse musculoskeletal injuries are highly correlated with paddling. However, there is a paucity of research for surfing injuries, and studies on overuse musculoskeletal injuries and prevention are disproportionally under-represented. Most of the prior studies are limited by small sample sizes, poor data collection methodology and geographical constraints. Further research is needed to establish preventative measures for both acute and overuse surfing injuries and to ensure the increasing popularity of surfing is met with an improved understanding of sport risks and safety. Specifically, we recommend research be prioritised regarding the efficacy of training programmes to prevent surfing-related overuse musculoskeletal injuries.

ObjectivesWhile the health benefits of running are legitimately advocated, participation in running can also lead to health problems. There is a high range of reported prevalence rates especially of running-related overuse injuries in high-level athletes and during competition. Little consensus exists for acute injuries and illnesses especially in recreational runners. Therefore, the aim of this study was to record the prevalence of health problems in recreational long-distance runners preparing for an event.MethodsRecreational runners aged 18–65 years who were registered 13 weeks prior to a half-marathon running event were invited to take part in this study. Participants were prospectively monitored weekly over 13 weeks by applying a standardised surveillance system for injuries and illnesses (Oslo Sports Trauma Research Center questionnaire). From this, prevalence and severity of acute and overuse injuries, as well as illnesses, were calculated.ResultsWe received 3213 fully answered questionnaires from 327 participants (40.7% female, 40.9±11.7 years of age, 31.5±21.1 km weekly mileage, 8.3±7.8 years of running experience). At any point in time over the preparation phase, 37.3% of the participants had health problems. Overuse injuries were the major burden (18%). They were followed by illnesses (14.1%) and acute injuries (7.9%). The median weekly severity score was 56.5 (IQR 37.0–58.0).ConclusionThe high prevalence of health problems in our cohort suggests that future efforts are needed to further specify the underlying mechanism and develop adequate prevention strategies for recreational runners.

Objective. The aim of the study was to determine the incidence and nature of injury patterns of South African international cricket players. Methods. A questionnaire was completed for each cricketer who presented with an injury during the 2004 - 2005 (S1) and 2005 - 2006 (S2) cricket seasons to determine the anatomical site, month, diagnosis and mechanism of injury. Results. The results showed that 113 injuries were sustained, with a match exposure time of 1 906 hours for one-day internationals (ODIs) and 5 070 hours for test matches. The injury prevalence was 4% per match, while the incidence of injury was 90 injuries per 10 000 hours of matches. Injuries occurred mostly to the lower limbs, back and trunk, upper limbs and head and neck. The injuries occurred primarily during test matches (43%), practices (20%) and practices and matches (19%). Acute injuries comprised 87% of the injuries. The major injuries during S1 were haematomas (20 %), muscle strains (14%) and other trauma (20%), while during S2 the injuries were primarily muscle strains (16%), other trauma (32%), tendinopathy (10%) and acute sprains (12%). The primary mechanisms of injury occurred when bowling (67%), on impact by the ball (batting – 65%, fielding – 26%) and when sliding for the ball (19%). Conclusion. The study provided prospective injury incidence and prevalence data for South African cricketers playing at international level over a two-season period, high-lighting the increased injury prevalence for away matches and an increased match injury incidence for test and ODI matches possibly as a result of increased match exposure time.

Context: Musculoskeletal injuries (MSKIs) are ubiquitous during initial entry military training, with overuse injuries in the lower extremities the most frequent. A common mechanism for overuse injuries is running, an activity that is an integral part of United States Coast Guard (USCG) training and a requirement for graduation. Objective: Assess the effects of athletic footwear choice on lower quarter MSKI risk in USCG recruits. Design: Descriptive Epidemiological Study Setting: USCG Training Center, Cape May, NJ Participants: A retrospective cohort study was performed in which 1229 recruits (1038 males, 191 females) were allowed to self-select athletic footwear during training. A group of 2876 recruits (2260 males, 616 females) who trained under a policy that required obligatory wear of prescribed athletic shoes served as a control. Main Outcome Measures: Demographic data and physical performance were derived from administrative records. Injury data were abstracted from a medical tracking database. Multivariable logistic regression was used to assess group, age, sex, height, body mass, and run times on MSKI outcomes. Results: Ankle-foot, leg, knee and lumbopelvic-hip complex diagnoses were ubiquitous in both groups (experimental: 20.37 to 29.34 per 1000 recruits; control: 18.08 to 25.59 per 1000 recruits). Group was not a significant factor for any of the injuries assessed. Sex was a significant factor in all injury types, with female recruits demonstrating ~2.00 greater odds of experiencing running-related injuries (RRIs), overuse injuries, or any MSKI in general. When considering ankle-foot or bone stress injuries, the risk in female recruits was 3.73 to 4.11 greater odds than their male counterparts. Run time was a significant predictor in RRI, all overuse injuries, and for any MSKI in general. Conclusion: While footwear choice did not influence MSKI risk in USCG recruits, female sex was a primary, nonmodifiable intrinsic risk factor.

Introduction According to the World Health Organization, in 2017, musculoskeletal diseases were the major contributors to global disability. Considering the exercise of functions in a professional context as an essential component in the daily life of human beings, it is in this environment that many of these injuries arise. The serious economic, labour and social repercussions that this type of injuries can cause brings us to the importance of analysing the current prevalence of these events in several industries, as well as the most affected body areas. Methods A literature search was carried out in the Pubmed and Web of Science databases, of articles published after 2015. The keywords used were “employee”, “skeletal muscle”, “injuries” and “industry/ sector”. This research resulted in 132 articles, of which 37 were revised to the full text and assessed their quality, which allowed the selection of 15 articles for a consequent analysis. Results Among the various industries, the tanning industry was the one with the highest global prevalence of musculoskeletal injuries (89.1%), 94.5% in females and 85% in males. In general, the prevalence of this type of injury in workers from different industries was around 70%. In most of the industries analysed (such as food, construction and textiles), the back/ lumbar area was the area most described as the origin of these injuries, with the exception of the printing industry, which reported a higher prevalence at the shoulder level. However, the back was the least identified region in the printing industry, being replaced, in this case, by the shoulder region. Discussion / Conclusion In general, and according to the data obtained, industrial workers are affected by a prevalence of musculoskeletal injuries that can vary between about 55% and 90%. The most affected regions of the body include the back, followed by shoulders, lower limbs and neck. The female sex was shown to be the most susceptible gender to contract musculoskeletal injuries, with respect to industrial workers.

AbstractMusculoskeletal injuries of the shoulder are a common presentation in primary care. Injuries to this highly mobile region can have a profound impact on the range of movement, resulting in severe functional limitation. The shoulder can also be one of the more complicated regions to examine due to its high mobility, poor localisation of pain and numerous supporting structures. This article aims to review the anatomy of the shoulder, examination technique and the pathology underlying common acute injuries in order to provide guidance to medical personnel deployed with the Royal Navy and Royal Marines.

Abstract Essential tremor (ET) is a neurological movement disorder characterised by bilateral limb kinetic/postural tremor, with or without tremor in other body parts including head, voice and lower limbs. Since no causative genes for ET have been identified, it is likely that the disorder occurs as a result of complex genetic factors interacting with various cellular and environmental factors that can result in abnormal function of circuitry involving the cerebello–thalamo–cortical pathway. Genetic analyses have uncovered at least 14 loci and 11 genes that are related to ET, as well as various risk or protective genetic factors. Limitations in ET genetic analyses include inconsistent disease definition, small sample size, varied ethnic backgrounds and many other factors that may contribute to paucity of relevant genetic data in ET. Genetic analyses, coupled with functional and animal studies, have led to better insights into possible pathogenic mechanisms underlying ET. These genetic studies may guide the future development of genetic testing and counselling, and specific, pathogenesis-targeted, therapeutic strategies.

Background: As previous epidemiological studies in elite ice hockey have focused on acute time-loss injuries, little is known about the burden of overuse injuries and illnesses in ice hockey. Purpose: To report the prevalence and burden of all health problems in male professional ice hockey players in Norway during a single competitive season. Study Design: Descriptive epidemiological study. Methods: A total of 225 male ice hockey players in the GET League (the premier professional league) in Norway reported all health problems (acute injuries, overuse injuries, and illnesses) during the 2017-2018 competitive season. Players reported all injuries and illnesses for 31 weeks using the Oslo Sports Trauma Research Center Questionnaire on Health Problems. Results: At any given time, 40% (95% CI, 37%-43%) of players reported symptoms from an injury or illness, and 20% (95% CI, 19%-22%) experienced health problems with a substantial negative impact on training and performance. Acute injuries represented the greatest incidence, prevalence, and burden (defined as the cross-product of severity and incidence). The most burdensome acute injuries were to the head/face, shoulder/clavicle, knee, and ankle. The most burdensome overuse injuries were to the knee, lumbar spine, and hip/groin. Conclusion: This registration captured a greater burden from overuse injuries than traditional injury registration, but acute injuries did represent a major problem. These data provide guidance in the development of prevention programs for both acute and overuse injuries, which should focus on the lumbar spine, hip/groin, and knee.

Introduction: Massive lower extremity trauma,in particular open tibial fractures with associated vascular injuries, present an immediate and complex decision-making challenge between a limb salvage attempt and primary amputation. Medical and surgical advances of the past two decades have improved the ability to reconstruct severely injured limb. Limbs that once would have been amputated are now routinely managed with complex reconstruction protocol. Mangled extremity severity score is one of the scoring systems to predict the fate of limbs after severe limb injuries.Methods: Patients fulfilling the inclusion criteria were evaluated with MESS, at the same time treatment protocol for management of injuries of lower limb were followed independently by attending orthopedic surgeon. Mean MESS for salvaged and amputated limbs were calculated and its reliability for prediction of fate of injured limb was assessed using software SPSS v16.Result: The age of patient ranges from 10 to 65 yrs with mean age 35.83. The most common mechanism of injury was Road Traffic Accident followed by fall from height. The mean MESS score for salvaged limbs was 4.18 and for amputated limbs was 8.12 suggesting significant difference in mean scores. The sensitivity (the probability that limbs requiring amputation will have MESS at or above 7) was found to be 75%. The specificity of MESS (the probability that salvage limbs will have MESS < 7) was 95.45%.Conclusion: MESS is a reliable indicator in decision making process whether a limb can be salvaged or needs amputation. The mangled lower extremity with the score of less than 7 may be salvaged and 7 or more may need amputation.JSSN 2015; 18 (1), Page: 23-25

ObjectiveTo investigate prevalence, incidence and profile of musculoskeletal injuries in para athletes.DesignSystematic review.Data sourcesSearches were conducted in MEDLINE, EMBASE, AMED, SPORTSDiscus, CINAHL and hand searching.Eligibility criteriaStudies were considered if they reported prevalence or incidence of musculoskeletal injuries in para athletes. Study selection, data extraction and analysis followed the protocol. Meta-analyses were conducted to estimate the prevalence and incidence rate among studies and subgroup analyses investigated whether methodological quality and sample size of the studies influenced on the estimated injury prevalence and incidence. The Grading of Recommendations Assessment, Development and Evaluation system determined the strength of evidence.ResultsForty-two studies were included. The prevalence of musculoskeletal injuries was 40.8% (95% CI 32.5% to 49.8%). Because of imprecision, indirectness and inconsistency, the strength of evidence was very low quality. The incidence of musculoskeletal injuries was 14.3 injuries per 1000 athlete-days (95% CI 11.9 to 16.8). The strength of evidence was low quality because of imprecision and indirectness. The subgroup analyses revealed that the sample size influenced on estimated injury prevalence and methodological quality influenced on estimated incidence. Injuries were more prevalent in the shoulder, for non-ambulant para athletes, and in the lower limbs, for ambulant para athletes.Summary/conclusionPara athletes show high prevalence and incidence of musculoskeletal injuries. Current very low-quality and low-quality evidence suggests that future high-quality studies with systematic data collection, larger sample size and specificities of para athletes are likely to change estimates of injury prevalence and incidence in para athletes.PROSPERO registration numberCRD42020147982.

Interaural Phase

1. Spike rates of cells in the cat's lateral superior olive (LSO) depend on interaural level differences (ILDs) and envelope interaural time differences (ITDs) of amplitude-modulated tones presented to both ears. We previously proposed that these sensitivities arise from a common mechanism, which is the IE binaural interaction (Inhibited by the contralateral and Excited by the ipsilateral ear). As a further test of that proposal and to gain a better understanding of the importance of this ITD-sensitivity, responses to monaural and binaural modulation are compared here over a range of modulation frequencies. 2. At low modulation frequencies, LSO-IE cells respond maximally when the envelopes of the amplitude-modulated stimuli at the two ears are out-of-phase by a half-cycle. This phase difference changes in a systematic way, which varies from cell to cell, when modulation frequency is increased. Mean interaural phase, measured over a range of modulation frequencies, was subjected to a characteristic delay analysis. Two measures were extracted: characteristic delay, which reflects differences in conduction delay between ipsi- and contralateral pathways, and characteristic phase, which reflects their sign of interaction. Most characteristic delays were within the physiological range of ITDs. There was a small bias toward positive delays, indicating a longer conduction time for the contralateral pathway. Characteristic phases were tightly distributed approximately 0.5 cycles, consistent with the proposed IE mechanism for ITD-sensitivity. 3. Increases in the modulation frequency of binaural stimuli beyond approximately 300 Hz consistently caused a profound decrease in average spike rate, as well as a decrease in the modulation of spike rate by ITD. The upper limit of ITD-sensitivity was 800 Hz. Sensitivity to envelope ITDs therefore is limited to a much lower range of frequencies than sensitivity to ITDs in fine-structure, e.g., as found in the medial superior olive (MSO), which operates up to several kilo Hertz. 4. A small sample of high-frequency EE cells (excited by both ears) in MSO also was tested with binaural amplitude-modulated stimuli. MSO-EE cells showed weak envelope ITD-sensitivity over a limited range of modulation frequencies. Consistent with the EE interaction, characteristic phases clustered approximately 0 cycles. 5. Mean interaural phase was compared with the phase of responses to monaural modulation. The difference between the ipsilateral and contralateral phases correlated well with the phase measured binaurally, both for LSO and MSO cells. 6. Many features of LSO-IE responses were mimicked by the simplest possible computer model, consisting of subtraction and rectification of low-pass filtered envelope waveforms. Differences between model and physiological results are suggestive of a temporal limitation in the binaural interaction that creates the ITD-sensitivity. 7. These results provide additional evidence for LSO ITD-sensitivity paralleling human psychophysical results. The stimulus boundaries within which ITD-sensitivity occurs suggest that it has a limited role in free-field conditions. It is traditionally thought that, to contribute to the perceived change in spatial location of a sound source, the LSO needs to show a change in overall firing rate summed across cells. This is achieved with small ILDs, but requires large ITDs, because the latter cue is less potent in single cells and has varied effects across cells by virtue of differences in characteristic delay.
