In the global context, about 1.25 million people die each year as a result of road traffic crashes. Moreover, road traffic injuries are the leading cause of death among young people, aged 15–29 years. Furthermore, 90% of the world's road fatalities occur in low- and middle-income countries (WHO, 2017). In Sri Lanka, the accident rate is increasing rapidly. According to the transport and civil aviation report, 2801 deaths, 2590 fatal accidents, 13,095 minor accidents, and 7719 critical accidents occurred in Sri Lanka in 2015. The trend of the accidents has been increasing due to many factors. Physical features of the roads and roadsides, behaviour of drivers and pedestrians are the main influence on the occurrence of accidents. Central province has many accidents-prone areas due to its spatial and temporal patterns. Landform and climatic factors such as fog, snow and rainfall trigger accident potentials. Therefore, this study, “Spatial and temporal patterns of road accidents and their challenges: a study on Nuwara-Eliya District” investigates reasons for the enhanced rate of traffic mishaps. This is the first such study of this phenomenon. Herein, we used primary and secondary data. The results indicate that physical features are mainly to blame.
Ergogenic aids have been used to alter joint kinematics in an attempt to minimise injury risk, yet the effectiveness of these aids may be compromised following a bout of exercise. This preliminary study aimed to measure the effect of compression garments and Kinesio Tape® on lower extremity joint alignment prior to and following an exercise bout. Eight male athletes (age = 24.1 ± 3.0 years, body height = 177.4 ± 5.2 cm, body mass = 72.3 ± 7.2 kg) volunteered to participant in this study. Joint kinematics were recorded whilst all participants performed three rotational lunges, in three conditions (control, compression garment, Kinesio Tape®), prior to and following a 10 minute exercise bout. Frontal plane kinematics (lateral pelvic tilt, knee valgus, ankle inversion/eversion) were used to assess ergogenic aid effectiveness during the lunge. Participants exhibited no significant differences in joint kinematics between ergogenic aid conditions prior to the exercise bout. Following exercise the only significant difference occurred within the Kinesio Tape® condition where maximum knee valgus angle significantly increased from 6.5° prior to exercise, to 7.7° following the exercise bout. The results of this study suggest joint kinematics are not affected by the ergogenic aids in this study prior to an exercise bout. However, there is evidence to suggest that the application of Kinesio Tape® may allow an increase in knee valgus angle following a bout of exercise, yet, compression garments are effective at maintaining joint alignment following a bout of exercise.
Purpose. Female runners typically suffer more from chronic running injuries than age-matched males, although the exact biome-chanical mechanisms behind the increased susceptibility of female runners are unknown. This study aimed to compare sex differences in tibiocalcaneal kinematics during the stance phase of running. Methods. Twenty male and twenty female participants ran at 4.0 m · s–1. Tibiocalcaneal kinematics were measured using an eight-camera motion analysis system and compared using independent samples t tests. Results. Peak eversion and tibial internal rotation angles were shown to be significantly greater in female runners. Conclusions. based on these observations, it was determined that female runners may be at increased risk from chronic injury development in relation to excessive tibiocalcaneal motions in the coronal and transverse planes.
Horse riding is a satisfying and exciting sport and recreation activity. However, it is not without risk. A large percentage of riders experience accidents of varying degrees of severity during their professional and recreational careers. Any injury, even one that appears to be harmless, may turn out to be serious and exclude a competitor from sport for a long period of time. The purpose of the following research was to analyse the presence and incidence of contusions and injuries among novice and professional riders. The material for this study was collected using a research questionnaire conducted on a group of 1973 people. Participants were chosen at random and belonged to an equestrian community from different age groups. The research was carried out all over Poland. Equestrianism is definitely an injurious physical activity, which is confirmed by the answer of 75% of respondents who consider this sport to have been harmful and have suffered an injury related to horse riding. Most respondents suffered hand contusions (45.5%), concussion (25.4%) and hand fractures (16.4%). The strength of the study was the number of respondents (1973) and feedback on, among others, various types of injuries. These injuries can be easily avoided due to increased knowledge, practice, and education.
The great popularity of foreign excursions and travel in exotic directions, as well as increasing popularity of breeding exotic animals at home, is evidence that in daily practice one may observe injuries inflicted by animals atypically occurring in Poland. The study presented and described a rare case of a patient attacked by a camel living in an agro-tourism farm in our country. Thanks to the combination of surgical and conservative treatment complete wound healing was observed, including the skin grafts, with preserved motor function of the foot.
Background: Recent epidemiological analyses in fencing have shown that injuries and pain linked specifically to fencing training/competition were evident in 92.8% of fencers. Specifically the prevalence of Achilles tendon pathology has increased substantially in recent years, and males have been identified as being at greater risk of Achilles tendon injury compared to their female counterparts. This study aimed to examine gender differences in Achilles tendon loading during the fencing lunge. Material/Methods: Achilles tendon load was obtained from eight male and eight female club level epee fencers using a 3D motion capture system and force platform information as they completed simulated lunges. Independent t-tests were performed on the data to determine whether differences existed. Results: The results show that males were associated with significantly greater Achilles tendon loading rates in comparison to females. Conclusions: This suggests that male fencers may be at greater risk from Achilles tendon pathology as a function of fencing training/ competition.
Introduction Despite the positive aspects of taking up physical activity, sport, in general, is inseparably associated with injuries, as well as straining or overloading of the musculoskeletal system. The aim of this study was to determine the functional state and injuries among young athletes practicing cross-country skiing. Material and methods A total of 65 individuals participated in the study. The test group consisted of 33 individuals practicing cross-country skiing, while the control group consisted of 32 persons not involved in this sport. The study was divided into two stages. The first stage consisted of a survey in which participants completed a personal questionnaire and were asked to answer 17 questions. Next, the Funtional Movement Screen (FMS) test was carried out in both groups using a specialty devised assessment form. Results The assessment of the risk of injury in both groups was similar, no statistically significant differences were found in this respect (p = 0.992). No statistically relevant relation was between the number of injuries sustained and the training experience of individuals in the test group (p = 0.056). There was no statistically significant relationship between the number of sustained injuries and the training experience of individuals included in the test group (p = 0.056), although this relationship was close to the threshold of statistical significance. Conclusions Cross-country skiing training had no significant effect on musculoskeletal injuries. The FMS test result did not correlate with previously sustained injuries. Individuals who adopted preventive training schemes were less likely to sustain injuries.
Previous work has postulated that shoulder pain may be associated with increases in both peak shoulder anterior force and peak shoulder proximal force. Unfortunately these relationships have yet to be quantified. Thus, the purpose of this study was to associate these kinetic values with reported shoulder pain in youth baseball pitchers. Nineteen healthy baseball pitchers participated in this study. Segment based reference systems and established calculations were utilized to identify peak shoulder anterior force and peak shoulder proximal force. A medical history questionnaire was utilized to identify shoulder pain. Following collection of these data, the strength of the relationships between both peak shoulder anterior force and peak shoulder proximal force and shoulder pain were analyzed. Although peak anterior force was not significantly correlated to shoulder pain, peak proximal force was. These results lead to the development of a single variable logistic regression model able to accurately predict 84.2% of all cases and 71.4% of shoulder pain cases. This model indicated that for every 1 N increase in peak proximal force, there was a corresponding 4.6% increase in the likelihood of shoulder pain. The magnitude of peak proximal force is both correlated to reported shoulder pain and capable of being used to accurately predict the likelihood of experiencing shoulder pain. It appears that those pitchers exhibiting high magnitudes of peak proximal force are significantly more likely to report experiencing shoulder pain than those who generate lower magnitudes of peak proximal force.
Introduction Hypermobility is diagnosed by detecting asymptomatic and increased mobility of the joints over accepted standards. It might be inborn or practiced. The second one is a result of regular exercising e.g. dance career which generates loads in excess of tissues’ capacity of repairing which is leading to many chronic injuries. Main purpose of the research was to detect a correlation between the joint hypermobility presence and the injury occurrence in jazz dancers group. Material and methods The research have been conducted among 30 jazz dancers and 30 non-dancers. There has been used a survey with the following questions related with the physical activity, treatment of the occurred injuries, type of the stabilizing exercises, pain’s frequency and intensity (VAS Pain). In order to examine a hypermobility Beighton Score was used. Results In 27 dancers the joint hypermobility was detected and 23 of them suffered an injury in their life. The most common type of injury was a biceps femoris muscle strain (12 people). An average number of points from Beighton Score was 5.53. In the control group the hypermobility was detected in 9 people. An average number of points was 2.13. Mostly dancers were complaining about the pain in the knee joint (15 people, avg. 2.07 VAS points). In the control group the pain was related with the lumbar spine column (12 people, avg. 1.33 VAS points). The points from Beighton Score reached by the dancers was correlated with the injuries occurrence. The time of doing stabilizing exercises had no impact on the prevalent contusions but there was a correlation between the time and the frequency and intensity of the pain. Conclusions Benign hypermobility joint syndrome was more common among the dancers than non-dancers and was related with pain occurrence.
Introduction Lower extremity injuries may be associated with proximal muscle weakness and decreased motor control. Our study aims to examine knee flexor and extensor muscle strength in athletes with and without trunk muscle strength asymmetry. Material and methods This matching control study involved a total of 80 athletes; 40 athletes with asymmetrical trunk muscle strength(asymmetric group) and 40 athletes with symmetrical trunk muscle strength(symmetrical group). Strength measurements of trunk and knee muscles were made with the IsoMed 2000 isokinetic device. Independent Samples T-Test or Mann Whitney-U test was used to compare variables according to their distribution status. The statistical error level was determined as p<0.05. Results In the symmetric group, the isokinetic muscle strength of the trunk flexor muscles was stronger than the asymmetric group (p<0.05) and the trunk extensor muscles were weaker than the asymmetric group (p 0.05). The Limb Symmetry Index(LSI) value of the two groups at 60°/sec was significantly different (p=0.032), and the dominant side in the symmetric group and the non-dominant side in the asymmetric group were stronger than the other side. Conclusions This result may be associated with knee joint injuries which are common in athletes with weak muscle strength, and can be attributed to the literature knowledge that core muscle weakness may increase the frequency of knee injury. Therefore, symmetrical core strengthening training can prevent possible injuries of athletes with asymmetrical trunk muscle strength. However, we think that more studies are needed to reveal this relationship.
Background and Study Aim: In this study, focusing on the individual difference in the characteristics of the knee joint, which plays an important role in weight bearing during walking, we examined the relationship between difference in knee alignment and pain in the legs during walking and effect of the pain on the psychological state of exercise performers. Material/Methods: A total of 40 subjects, including 25 healthy men and 15 women were recruited to this study. Knee alignment was classified according to the intercondylar and intermalleolar distances by increments of 2.0 cm. After walking (85km) on day 3 of the 5-day event, subjects were required to answer a questionnaire asking where in the leg they had pain. The psychological state of each subject was assessed by performing the Profile of Mood States (POMS) after they had rested after walking on each of days 1, 2 and 3 of the 5- day event. Results: The following sites exhibited significant differences in the number and incidence of injury between groups: the anterior side of lower leg (p <0.05), posterior side of lower leg (p <0.01), ankle joint (p <0.05) and sole of foot (p <0.01). In the genu valgum group, the score for factor V(:Vigor) decreased by 4.0 points between days 1 to 3: 18.1 ± 4.6 points on day 1 and 14.1 ± 7.6 points on day 3, with a significant difference between days 1 and 3. Conclusions: When performing an exercise that places load on the legs, such as walking, one should consider the risk of injury by measuring the individual’s knee alignment before commencing the exercise.
The purpose of this study was to examine kinematic and kinetic differences in low and high intensity hand support impact loads during a forward handspring vault. A high-speed video camera (500 Hz) and two portable force platforms (500 Hz) were installed on the surface of the vault table. Two-dimensional analyses were conducted on 24 forward handspring vaults performed by 12 senior level, junior Olympic program female gymnasts (16.9 ±1.4 yr; body height 1.60 ±0.1 m; body mass 56.7 ±7.8 kg). Load intensities at impact with the vault table were classified as low (peak force < 0.8 × body weight) and high (peak force > 0.8 × body weight). These vaults were compared via crucial kinetic and kinematic variables using independent t-tests and Pearson correlations. Statistically significant (p < 0.001) differences were observed in peak force (t(24) = 4.75, ES = 3.37) and time to peak force (t(24) = 2.07, ES = 1.56). Statistically significant relationships between the loading rate and time to peak force were observed for high intensity loads. Peak force, time to peak force, and a shoulder angle at impact were identified as primary variables potentially involved in the determination of large repetitive loading rates on the forward handspring vault.
Impairment of motor function following peripheral nerve injury is a serious clinical problem. Generally nerve injury leads to erroneous control of muscle activity that results in gait and voluntary movement abnormalities followed by muscle atrophy. This article presents a review of studies on the effects of peripheral nerve injury on the motor system performed on animal models. We focused our attention on the results that are fundamental for better understanding of the degenerative and regenerative processes induced by nerve injury as well as of the mechanisms of structural changes in neuronal networks controlling movement. Quoted results are also important for clinical applications because they allow to develop new diagnostic and therapeutic techniques that can be used after nerve injury inducing motor deficits. However, till now no efficient therapy inducing satisfactory recovery was found. There is still a need to continue an advanced basic research directed to develop effective therapies. Thus the aim of this review is to compare the results of recent studies performed on various animal models in order to propose new methods for identification of mechanisms responsible for muscle deficits and propose targets for new pharmacological therapies.
The aim of the study was to assess the effectiveness of the medical rescue service in the city of Łódź and its surrounding areas.Material and methods. The records of the forensic-medical postmortems conducted at the Institute of Forensic Medicine Medical University in Łódź in 2004 were analyzed. For further analysis, the cases of adults who died of mechanical injury resulting from an accident were chosen. Taking into consideration the autopsy diagnosis, the degree of the individual injuries was defined with the use of the Abbreviated Injury Scale (AIS). Next, the Injury Severity Score (ISS) and the New Injury Severity Score (NISS) were calculated. In cases where specialist medical assistance was given, the medical documentation was analyzed, and the clinical condition of the injured was assessed using the Revised Trauma Scale (RTS), followed by estimation of the probability of survival with the use of the TRISS (Trauma Revised Injury Severity Score).Results and conclusions. Among the analyzed 194 cases of death caused by a mechanical injury resulting from an accident, 19 cases (9.8%) were recognized as preventable (ISS 0-14 or/and NISS 0-14 and/or TRISS >75%). It was established that the deaths assessed as preventable were caused by early or late injury complications, which even correct treatment cannot always prevent.
Lateral ankle sprains are one of the most common injuries in athletics. Injury to lateral ankle ligaments can result in persistent instability of the ankle joint, known as functional ankle instability (FAI). Two methods of treating FAI are ankle taping and ankle bracing. The purpose of this study was to compare the effects of ankle taping and ankle bracing on ankle joint kinematics and kinetics during a landing task. Methods: Seven individuals with FAI and seven healthy controls performed three landing trials in each of three conditions: control, taped and braced. Ground reaction forces and three-dimensional kinematics were collected simultaneously while participants performed single-leg step-off landing trials from a box with a height of 0.6m. Peak ankle joint angles and moments were calculated using customized software. Results: Individuals with FAI produced significantly smaller inversion moments compared to healthy controls (p = 0.006). Ankle stabilization did not significantly alter ankle joint angles, ranges of motion or moments. Discussion: The present findings suggest that individuals with FAI exhibit unique ankle biomechanics independent of ankle stabilization modality. Future research may seek to investigate the multi-joint biomechanical adaptations associated with ankle stabilization in individuals with FAI compared to healthy controls.
Antarctica is one of the last great wilderness areas on Earth. Early Antarctic expeditions during the Heroic Age of Antarctic discovery (1895–1922) returned reports of frostbite, scurvy, snow blindness, and death. Today, over 50,000 people travel to the Antarctic each year via research expeditions, commercial cruise ships (tourism), and research cruises. This study reviewed the existing research reporting the health challenges encountered during modern day travel to Antarctica. The results identified a transition from the Heroic Age when death was common to a contemporary time when death is an uncommon event. The review identified musculoskeletal and soft tissue injuries resulting from moving equipment and supplies to be the most common health challenge encountered by long-term land expeditions. Digestive issues such as constipation and dyspepsia were also common in during the coldest months. For tourist oriented commercial cruise ships, motion sickness resulting from rough seas was most prominent. Specifically, the small nature of the cruise ships made them prone to rough seas in Drakes Passage. During scientific cruises where research is primarily conducted aboard the ship, dermatological conditions (viral, fungal, bacterial) such as dry skin, dry lips, eczema are the most common health challenge. Musculoskeletal and soft tissue injuries are also common given the physical challenge associated with strenuous research.
The anatomical structure of urogenital system contributes to high risk of mechanical injuries. The group which is particularly exposed to renal injuries are young men doing sports, the injured of road accidents, victims of accidents in the house or at work. The authors present the medical and surgical treatment after renal injuries. There are blunt and penetrating renal injuries as well as a 5-level classification of kidney injuries according to a degree of injuries – AAST. This classification enables to perform a standardization of different patient groups to choose a proper therapy and to predict the results of treatment. The most of renal injuries involves the medical treatment. However, it is often needed the surgical intervention. The indications for surgical treatment are haemodynamic instability, necessity of surgical verification of concomitant injuries, expanding or throbbing perirenal haematoma confirmed in laparotomy, grade 5 injury. The patients with the serious renal injury should undertake necessary medical examinations to determine a range of injury and to undertake the appropriate treatment. Furthermore, the longterm medical controls are recommended. The contemporary treatment’s approaches, especially AAST scale, are going to medical treatment of blunt renal injuries. The injuries of 1–3 grade are usually treated conservatively and in case of grade 4 and 5, a surgical procedure is needed. Conservative treatment of grade 1–3 injuries does not relate to a risk of late complications. The renal-vascular injuries of 5 grade are treated as an absolute indication for exploratory surgery.

Budowa anatomiczna układu moczowo-płciowego naraża go na liczne urazy mechaniczne. Grupę szczególnie wysokiego ryzyka stanowią młodzi mężczyźni uprawiający sport, uczestnicy wypadków drogowych, ofiary wypadków w domu lub w miejscu pracy. Autorzy omawiają postępowanie zachowawcze i operacyjne po urazach nerek. Wyróżnia się urazy tępe i penetrujące oraz pięciostopniową klasyfikację urazów nerek według stopnia odniesionych obrażeń – AAST. Klasyfikacja ta pozwala na dokonanie pewnej standaryzacji różnych grup pacjentów i wyboru właściwej terapii oraz stwarza możliwość przewidywania wyników leczenia. Choć w przeważającej liczbie przypadków urazy nerek są leczone zachowawczo, dość często konieczna jest interwencja chirurgiczna. Wskazaniami do leczenia operacyjnego są: hemodynamiczna niestabilność, konieczność weryfikacji operacyjnej urazów towarzyszących, powiększający się lub pulsujący okołonerkowy krwiak stwierdzony podczas laparotomii, V stopień urazu. Pacjenci z poważnym urazem nerki powinni być poddawani niezbędnym badaniom kontrolnym w celu określenia zakresu urazu i wprowadzenia stosownego leczenia. Ponadto zaleca się im podjęcie kontroli długoterminowych. Współczesne algorytmy postępowania, zwłaszcza skala AAST, preferują zachowawcze leczenie tępych urazów nerek. Urazy I–III stopnia leczone są zwykle zachowawczo, w przypadku urazów IV i V stopnia wymagana jest eksploracja chirurgiczna. Leczenie zachowawcze urazów I–III stopnia nie niesie ze sobą ryzyka późnych powikłań. Urazy nerkowo-naczyniowe V stopnia są traktowane jako absolutne wskazanie do leczenia chirurgicznego.
Dekspantenol – prekursor witaminy B5 – jest związkiem pochodzenia naturalnego, który ma znany od dawna dobroczynny wpływ na nawilżenie skóry i błon śluzowych oraz na gojenie się nabłonków. W leczeniu wykorzystuje się również jego aktywność przeciwzapalną. Wpływ dekspantenolu na tkanki powierzchowne był obserwowany w licznych badaniach in vitro i in vivo, jednak dokładny mechanizm działania nie został do tej pory poznany. W okulistyce dekspantenol jest znanym i szeroko stosowanym lekiem u pacjentów z ostrymi i przewlekłymi chorobami powierzchni oka oraz następstwami urazów rogówki.

Dexpanthenol - a precursor to vitamin B5 - is a compound of natural origin that has a long-known beneficial effect on skin and mucous membrane hydration and epithelial healing. Its anti-inflammatory activity is also used in treatment. Its effects on superficial tissues have been observed in numerous in vitro and in vivo studies, but the exact mechanism of action has not yet been understood. In ophthalmology, dexpanthenol is a well-known and widely used drug in patients with acute and chronic diseases of the ocular surface, as well as for treating the sequelae of corneal injuries.
While celebrated as a highly popular sport in Canada, there are many social problems existing within and around Canadian ice hockey. These problems are often overlooked and rarely depicted in academic and journalistic research on sport. These social problems include, but are not limited to: extreme violence resulting in injuries and death, hazing rituals, multiple types of sexual violence, drug abuse, financial corruption, as well as various forms of prejudice and discrimination. Prompted by pop-cultural depictions in films, this paper further identifies and explores social problems in Canadian ice hockey revealing the realism embedded within various seemingly fictional films.

Background. The purpose of this study was to collect current research lines in American football regarding the ankles and the foot. The specific goal was to determine how American football affects the ankle joints and the foot, i.e. the frequency, causes and types of injuries as well as various links between the footwear and failure of these structures. Material and methods. The study included 26 publications, drawn mainly from PubMed and related databases, meeting the search criteria. Results. As a result of the review of the publications, the frequency and types of ankle and foot injuries with regard to lower limbs were discussed along with the conditions predisposing for such injuries. Current works focus primarily on injury surveillance databases and on the research on the impact of footwear on the foot and ankle joint. There are works showing the relationship between ankle and foot injuries on the one hand, and the balance on the other. Additionally, some of the articles deal with the past treatments, the time of exclusion from the game and the use of stiffeners to protect the players against overloads and damage to the above-mentioned structures. Conclusions. Our research draws attention to the problem of foot and ankle injuries and shows that preventive, training and physiotherapeutic programs should still be improved due to their high level of trauma. More clinical study is needed to find the specific causes of injuries and prevent them effectively.
