In the last few years, the development of national and international games for the physically challenged has encouraged greater participation of athletes with physical disabilities. This resulted in an increase in intensity and frequency of the training routines and competitions and higher levels of trauma-orthopedic lesions. The aim of this descriptive-comparative study is to analyze statistically the incidence of trauma-orthopedic lesions of 82 physically challenged athletes selected in a non intentional and no probalistic way. These athletes belong to various sports categories, as follows: swimming = 37, table tennis = 19, athletics = 19, power lifting = 7. Sixty are males, 24, females, they range in age from 15 to 51 and they all took part in the 2002 World Championship. Applying the medical records of the Brazilian Paraolimpic Committee medical department filled in at those events (the technique of observing the athlete clinical-sports files and medical examinations), the result showed a recurrence of lesions in athletes in the following sports: athletics (MMII = 64.9%, backbone 19.3% and MMSS = 15.8%; power lifting (backbone = 54.5%, MMSS = 36.4% and MMII = 9.1%); swimming (MMSS = 44.4%, backbone = 38.9% and MMII = 16.7%) and table tennis (MMSS = 56%, Backbone = 36% and MMII = 8%). Such results lead to the conclusion that the performing of sports of the physically challenged athletes, and also the intensity of the training routing to try to beat their previous marks and results, cause these kinds of lesion. In addition, it is important to reinforce the preventive measures to the athletes.

Most research on sport injuries in disabled athletes uses a cross-disability (physical and sensorial) design and merges different sport modalities in the same study. This procedure creates difficulties in interpreting the results, since different disabilities and modalities may cause different injury conditions. The purpose of this study was to analyze the sports injuries frequency in visually impaired athletes, to identify the site of the injury, its mechanism, and the main injuries that occur to these athletes as well as to verify if the visual class relates to the sports injury frequency. The subjects were male and female visually impaired athletes, members of the Brazilian team of athletics, soccer 5, goalball, judo, and swimming, who played in international competitions between 2004 and 2008. Data was collected using the Brazilian Paralympic Committee and the Brazilian Confederation of Sports for the Blind medical form, which included the following information: name, age, modality, competition, visual classification (B1, B2, B3), injury type, location of injury, and diagnosis. A total of 131 athletes participated in this study: 42 female, 89 male amongst which 61 were B1, 46 B2, and 24 B3. From this total, 102 athletes reported 288 sports injuries; 2.82 injuries per athlete. Female athletes presented more injuries than male athletes; however, this difference did not show statistical significance. Regarding visual classification, B1 athletes got more injuries than B2 athletes, and these more than B3 athletes; statistically significant difference was found only between B1 and B3 group. As one group, athletes presented similar values between accident and overuse injuries. Concerning body segment, lower limbs showed more injuries, followed by upper limbs, spine, head, and trunk. Twenty-one diagnoses were reported, being tendinopathies, contractures, and contusions the most frequent.

ObjectiveDemonstrate the presence and magnitude of biomechanical variables during gait in patients with medial knee osteoarthritis (OA) and the relationship with the knee loading.MethodsGait of 21 subjects diagnosed with medial knee OA was evaluated and compared to the control group.ResultsThe group with OA showed: Lower gait speed (0.8 ± 0.1 vs. 1.1 ± 0.1m/s), higher peak early (2.6 ± 1.2 vs. 0.3 ± 1.4 Nm/Kg) and late peak of the adduction moment (1.8 ± 0.7 vs. 0.9 ± 0.2 Nm/Kg), higher peak flexor moment (1.6 ± 0.9 vs. 0.6 ± 0.4 Nm/Kg), high dynamic peak varus (11.5º ± 8.3 vs. 3º ± 3.9), higher peak flexion (15.6º ± 8 vs. 9.3º to ± 4.1), with a flexion tendency (5.5º ± 8.5) in the stance phase, smaller peak of flexion (58.7º ± 13.3 vs. 67.5º ± 4.8) in the balance phase and higher peaks of external rotation (25.5º ± 12.7 vs. 0.5º ± 22.4).ConclusionPatients with medial knee OA show changes in gait with increased external rotation, speed reduction, increased flexor moment and flexion in the stance phase, insufficient for reduction of the load. Level of Evidence III, Case Control Study.

Even in a short follow-up of 6 months, HTO determines positive results in biomechanical gait, not only in the coronal plane but also in the sagittal and axial planes and should be taken into account during the rehabilitation process.
