Arm Pump is a well known phenomena in the motocross. It causes pain in the arm due to a compression and is a common disorder among even skilled motocrossers. The etiology of this pain is not well ...understood although it may be related to excessive muscle tension and inappropriate posture. Most likely the pain is the result of dysponesis in which the motocross cyclist does not relax the muscles. This single case report demonstrates the use SEMG for diagnosis and development a successful clinical intervention. The subject was a 16 year old male who experienced severe pain after 10 min of riding. In the office, SEMG was recorded from the extensors of the underarm muscles while mentally rehearsing riding his motorbike. In the simulation, the EMG showed high activity (up to 40 pV) in the underarm muscles, as long as he was thinking of riding his motorbike. The SEMG training protocol consisted on teaching microbreaks (a 1 s epoch in which the SEMG decreased to 2-5 pV) while mentally riding. After 10 min of SEMG training he was able to make small microbreaks. The post SEMG recording with an imagery riding of the same circuit, showed a significant decrease in SEMG and numerous microbreaks. The second therapeutic session was at the actual motocross circuit where corrections of posture and arm position on the motorbike were given. Using appropriate language cues such as "feel the weight in your arms" facilitated relaxing of the muscles during the actual circuit riding. After these two interventions, he was able to drive for more than 2 h without any complaint. The rapid decrease in symptoms occurred most likely because of the dynamic relationship between the body posture and the motocross cycle. Combining mirror, photo and SEMG feedback demonstrated how to sit in an appropriate position on the bike as well as perform microbreaks. This case report suggests that changes in SEMG and body posture training should be used as a possible treatment and preventative approach for Arm Pump symptoms. Adapting this approach to sport specific symptoms may eliminate symptoms and improve performance. Keywords * SEMG * Arm Pump by Motocross * Peak performance
Musculoskeletal injuries often occur when performing motocross; almost half of the overall ligamentous injuries (42%) are knee ligaments injuries. Lesions can be greatly reduced with knee braces. ...Commercial knee braces are expected to oppose and limit unwanted and potentially harmful movements such as hyperextension and excessive rotation of the knee joint. However, this aspect has not been fully investigated from a biomechanical point of view. This would require proper Finite Element Modelling (FEM) and Analysis (FEA). However, to perform FEA and evaluate the efficacy of the brace simulating sportive conditions, numerical models need to be built. It requires a dedicated setup and several preprocessing steps, for which no industrial standard or widely accepted better practise is available as of today. Firstly, the brace and the lower limb are scanned using a 3D scanner. The geometry is reconstructed using reverse engineering techniques. These allow us to obtain a smooth, reliable 3D model starting from the points cloud acquired during scanning. A lower limb model was created using a mixed approach, combining MRI data and 3D scanning. Finally, a simulation of the impact condition after a jump using the developed model was carried out.
Background: Motocross is one of the most popular motorized off-road sports, characterized by riding on irregular natural terrain of hard earth and/or sand with various obstacles throughout the ...course. Objectives: This study evaluated the influence of a motocross training session on neuromuscular response and blood lactate in amateur riders. Patients and Methods: Nine motocross riders (22.7 ± 2.8 years) participating in amateur competitions at the state level conducted a training session of 20 minutes duration at a motocross track (1.6 km) with a 250-cc four-stroke motorcycle. Metabolic demand was measured with blood lactate concentrations before and immediately, 3, 5, 8, and 10 minutes after the training session. To measure neuromuscular response, riders completed handgrip strength and horizontal jump tests before and 10 minutes after the training session. Student's t-test and analysis of variance one-way repeated measures were used to compare the changes before and after the motocross training session. Results: Significant decreases in handgrip strength were observed for both hands (left: P= 0.010 and right: P = 0.004). However, no significant difference (P= 0.241) in horizontal jump ability was observed. Significant blood lactate values were observed immediately (P= 0.001), 3 (P= 0.001), 5 (P= 0.001), and 8 (P = 0.01) minutes after training when compared to the value before training. The peak blood lactate value was 6.5 ± 2.7 mMat 8 minutes after the training session. Conclusions: Amateur motocross riders had significant anaerobic metabolism demands and had reduced handgrip strength following a training session. These data suggest an importance of physical training aimed at improving anaerobic and neuromuscular performance of the upper limbs in amateur motocross riders. Keywords: Lactate, Metabolism, limbs

Background
Motocross is a high-risk form of motorbiking where serious injuries occur regularly, although little data have been collected to illustrate this relationship. Over 5 years, teams from RJAH ...Oswestry and RSH sought to demonstrate the impact of Motocross on orthopaedic presentation and workload.
Method
Data were collected prospectively over 5 years including 615 orthopaedic injuries associated with both recreational and competitive motocross.
Results
An increase in injury and operation frequency was observed, young males were identified as the highest risk participant. This was evident over winter and weekends, during the competitive racing season. A variety of injuries have been implicated, some with life threatening or disabling consequences.
Conclusion
Motocross has seen exponential growth in popularity with increases in injuries and operations. This implicates major impacts on finances and healthcare, especially at times of seasonal vulnerability. The authors encourage event organisers to explore the avenues of rider safety in this increasingly popular sport.
Motocross-related injury patterns and outcomes are poorly understood. The purpose of this analysis was to characterize the epidemiology, injury patterns, and outcomes of motocross collisions. These ...parameters were compared with motorcycle collisions for context.
The National Trauma Databank (NTDB) (2007-14) was used to identify and compare injured motorcycle and motocross riders. Variables extracted were demographics, Abbreviated Injury Scale for each body area, Injury Severity Score, and emergency department vital signs. Outcomes included mortality, ventilation days, intensive care unit length of stay, and hospital length of stay.
Of the 5,774,836 NTDB patients, 141,529 were involved in motocross or motorcycle collisions (31,252 motocross and 110,277 motorcycle). Overall, 94.4% were drivers and 87.4% were male. Motocross riders were younger (23 vs. 42, p < 0.001), more likely to use helmets (68.9% vs. 54.1%, p < 0.001), and less likely to have used alcohol (8.4% vs. 23.0%, p < 0.001). Head and chest injuries were less common in motocross patients (28.6% vs. 37.2%, p < 0.001; 25.5% vs. 37.7%, p < 0.001, respectively), as were Injury Severity Score of greater than 15 and Glasgow Coma Scale of less than or equal to 8 (18.2% vs. 28.1%, p < 0.001; 3.7% vs. 7.7%, p < 0.001, respectively). Overall mortality was significantly lower in the motocross group (0.3% vs. 1.4%, p < 0.001). Stepwise logistic regression analysis identified age of older than 60 years, Glasgow Coma Scale of less than or equal to 8, hypotension on admission, head Abbreviated Injury Scale of greater than or equal to 3, and riding a motorcycle, either as a driver or passenger, to be independent predictors of mortality. Subgroup analysis revealed being a motocross driver or passenger to be an independent predictor of improved survival (odds ratio OR, 0.458; 95% confidence interval CI, 0.359-0.585; p < 0.001 and OR, 0.127; CI 95%, 0.017-0.944; p = 0.044, respectively). Helmets were protective against mortality for all patients (OR, 0.866; 95% CI, 0.755-0.992; p = 0.039).
Motocross and motorcycle collisions are distinct mechanisms of injury. Motocross riders are younger, more likely to wear protective devices, and less likely to use alcohol. Motocross collisions are associated with better outcomes compared with motorcycle collisions. Wearing a helmet is associated with improved survival for all riders.

•Off-road motorcycle sports are increasingly popular, however paediatric injuries frequently occur and are associated with significant morbidity.•Concerns regarding the safety of this sport are ...highlighted by the death of four children (2010-2017) and the number of children sustaining major trauma.•While paediatric off-road motorcycle trauma presentations to hospital are less in number compared to other sports, the injury risk and severity is higher.•Riders and parents need to be aware of these risks, and organised events need to have adequate on-site first aid facilities.
Paediatric participation in competitive and recreational off-road motorcycle sports is increasing in popularity worldwide, however injuries frequently occur and the sport is associated with significant morbidity.
This study describes the profile of paediatric off-road motorcycle trauma attended by emergency medical services (EMS) in Victoria, Australia.
A retrospective review included paediatric (<16 years) competitive and recreational off-road motorcycle patients attended by EMS between 2010 and 2017 in the State of Victoria, Australia. Patient characteristics and injuries sustained were described using descriptive statistics. Predictors of EMS transport were identified using multivariable logistic regression analyses.
There were 1,479 paediatric motocross patients attended by EMS between 2010 and 2017. This represents 1.6% of the total state-wide EMS paediatric trauma (<16 years) workload, and equates to an average incidence of 22.2 per 100,000 population. The median age of patients was 13 years (IQR: 10-14) and 89.5% were male. The most common final diagnoses recorded by paramedics were 'fractures' (25.5%, n = 377) and 'unspecified pain' (19.5%, n = 289). Administration of analgesia (76.3%) was the most common EMS management, followed by spinal immobilisation (54.7%) and splinting (33.4%). The vast majority (91.5%) of patients were transported to hospital by EMS. Following admission, 38 (2.6%) patients were confirmed to have sustained major trauma, 78.9% of which had been transported direct from scene to a major trauma centre for definitive care. Median ISS for confirmed major trauma patients was 14 (IQR: 14-22). Four (0.4%) patients received pre-hospital CPR. All four sustained injuries from recreational off-road, motorcycle activities and all four cases died, two at the scene and two in-hospital.
Off-road motorcycle activities are an important cause of death and injury in Victorian children, as highlighted and demonstrated by the four deaths and high EMS transport rates borne out in this study. Riders and parents need to be aware of these risks, and organised events must have adequate on-site medical care resources.
