The ankle is the joint most affected among the sports-related injuries. The current study investigated whether certain intrinsic factors could predict ankle sprains in active students. The 125 participants were submitted to a baseline assessment in a single session were then followed-up for 52 weeks regarding the occurrence of sprain. The baseline assessment were performed in both ankles and included the questionnaire Cumberland ankle instability tool - Portuguese, the foot lift test, dorsiflexion range of motion, Star Excursion Balance Test (SEBT), the side recognition task, body mass index, and history of previous sprain. Two groups were used for analysis: one with those who suffered an ankle sprain and the other with those who did not suffer an ankle sprain. After Cox regression analysis, participants with history of previous sprain were twice as likely to suffer subsequent sprains [hazard ratio (HR) 2.21 and 95% confidence interval (CI) 1.07-4.57] and people with better performance on the SEBT in the postero-lateral (PL) direction were less likely to suffer a sprain (HR 0.96 and 95% CI 0.92-0.99). History of previous sprain was the strongest predictive factor and a weak performance on SEBT PL was also considered a predictive factor for ankle sprains.

ResumoIntrodução: Avaliar a produção do conhecimento de uma área pode facilitar a compreensão de sua identidade, bem como apontar quais rumos está percorrendo. Objetivo: Verificar qual a área de estudos e os descritores de maior ocorrência em artigos publicados em revistas de circulação nacional voltadas à fisioterapia. Método: Trata-se de uma pesquisa documental com abordagem qualitativa e quantitativa dos dados por meio da análise de conteúdo e da contagem das aparições dos descritores. Foram incluídos resumos de periódicos de fisioterapia brasileiros, com classificação maior ou igual a B2 no WebQualis e acesso livre em ¹ Janeisa Franck Virtuoso, Alessandro Haupenthal, Natália Duarte Pereira, Caroline Pereira Martins e Rodrigo José Knabben foram responsáveis pela produção do texto e Alexandro Andrade pela orientação e revisão do artigo.Fisioter Mov. 2011 jan/mar;24(1):173-80Abstract Introduction: To evaluate the production of knowledge from one area may facilitate the understanding of their identity as well as pointing out which direction is traveling. Objective: To determine which area of studies and greater occurrence of descriptors in articles published in magazines at physiotherapy in periodicals of national circulation. Method: This is a documental research with a qualitative approach through content analysis. We included abstracts from journals of physiotherapy Brazilians, ranked higher or equal to B2 in WebQualis and free access to the website. With these criteria was selected: Brazilian Journal of Physical Therapy and Physical Therapy in Movement, from 1996 to 2009. The items discussed were: keywords and study area. We used the program to count words TextStat. Results: We analyzed 726 articles. Areas of study occurred more frequently orthopedics, neurology, pulmonology and pediatrics, which together comprise 65% of production in physical therapy, and orthopedics, alone accounts for 36% of the studies. In relation to the keyword, the prevalence was highest descriptor physiotherapy, followed by elderly and physical activity. Discussion: As for area studies, especially considering the practice of orthopedics physical therapist that has historically focused on hospitals and rehabilitation clinics under the supervision of the orthopedic doctors and seeking its independence a second time.In relation to the descriptors, the highest frequency of the word therapy should be reassessed by the researchers, because it reflects the content of studies. Conclusion: The scientific production in orthopedics was more frequent, reflecting the largest professional performance. [#] [K]

When thinking about load values in water running professionals should consider not only the immersion level, but also the speed, as it can affect the force components, mainly the anteroposterior one. Quantitative data on this subject could help professionals to conduct safer aqua-tic rehabilitation and physical conditioning protocols.

The analysis of validity and repeatability of the prototype for measuring isometric muscle strength has shown to be good or excellent, depending on the knee joint angle analyzed. The new instrument, which presents a relative low cost and easiness of transportation when compared with an isokinetic dynamometer, is valid and provides consistent data concerning isometric strength of knee extensors and, for this reason, can be used for practical, clinical, and research purposes.
