Introdução: Com o intuito de prevenir e minimizar o impacto de lesões músculoesqueléticas é de extrema relevância a formação em ergonomia dos estudantes
de medicina dentária. Dispositivos eletrónicos portáteis podem ser utilizados
para treinar um indivíduo a melhorar a perceção da sua postura e modificá-la
através de um sistema de biofeedback. O objetivo principal deste estudo é
analisar o efeito que um dispositivo de biofeedback para treino postural tem na
postura do estudante de medicina dentária. Como objetivo secundário pretendese avaliar a aplicabilidade do dispositivo postural no ensino de princípios de
ergonomia em medicina dentária.
Materiais e Métodos: Este é um estudo piloto que consiste na utilização de um
sensor de treino postural por biofeedback UpRight GO 2TM (Upright Technology
Ltd., Tel Aviv, Israel). Foram recolhidos dados diários da percentagem de tempo
em que os 5 participantes obtiveram uma postura correta durante sua utilização,
com recurso à aplicação do dispositivo de biofeedback. Foram também
analisados os dados durante procedimentos clínicos dentários simulados num
fantoma antes e depois de 4 semanas de treino postural. Avaliou-se através do
Questionário Nórdico a presença de sinais e sintomas músculo-esqueléticos.
Também se analisou a perceção dos participantes sobre a utilização do
dispositivo biofeedback através de um questionário.
Resultados: A postura dos estudantes de medicina dentária melhorou após a
utilização do dispositivo de biofeedback UpRight GO 2TM, e de acordo com a
opinião dos participantes além de recomendaram a sua utilização, consideram
que o sensor acarreta vantagens na adoção de uma melhor postura durante o
exercício da profissão e também de uma forma geral.
Conclusão: Constatou-se que a utilização de sistemas de biofeedback, está
associada a uma melhoria da postura dos estudantes de medicina dentária. O
treino postural com este dispositivo parece ser exequível no contexto médicodentário.

The main purpose of this study is to analyze the effect a biofeedback device for postural training has on dental students' posture. As a secondary aim it is intended to evaluate the applicability of the postural device in teaching ergonomic principles in dentistry. Materials and Methods: This is a pilot study that consists of using a biofeedback postural training sensor UpRight GO 2TM (Upright Technology Ltd., Tel Aviv, Israel). Daily data were collected regarding the percentage of time the 5 participants achieved correct posture during its use, using the biofeedback device. Data were also analyzed during simulated clinical dental procedures on a phantom before and after 4 weeks of postural training. The Nordic Questionnaire was used to assess the presence of musculoskeletal signs and symptoms. The participants' perception of the use of the biofeedback device was also analyzed through a questionnaire. Results: The dental students' posture improved after using the UpRight GO 2TM biofeedback device, and according to the participants' opinion besides recommending its use, they consider that the sensor carries advantages in adopting a better posture during the exercise of the profession and also in general. Conclusion: It was found that the use of biofeedback systems is associated with an improvement in the posture of dental students. Postural training with this device seems to be feasible in the medical-dental context.
