Resumo: | The objective of this study was to validate a new stabilometric force platform (SFP). For this, three steps have been established: a) to determine the force threshold to reach an acceptable level of accuracy of the centre of pressure (CoP) measurement by the application of single point load; b) to determine the accuracy of the CoP measurement in the application of distributed load simulating the human feet; c) to verify the concurrent validity of the SFP by comparing it with a commercial force platform (FP). The tests performed in steps “a” and “b” were conducted by applying loads on the SFP using a universal testing machine. In the application of single point load, the mean force threshold presented by the SFP was 315.6 ± 140.5 N. The CoP measurement error in the points near the centre of the SFP was 1.04 ± 0.80 mm in medial-lateral (ML) and 1.31 ± 0.99 mm in anteriorposterior (AP) direction. In the points near the edges of the plate, the error was 2.03 ± 0.91mm (ML) and 1.54 ± 0.96 mm (AP). In the test with distributed loads, errors of less than 1mm were found. Additionally, no differences were found in the CoP parameters between SFP and the FP. The CoP measurement signal presented high correlation between both equipments in AP (r = 0.997 ± 0.001) and ML (r = 0.988 ± 0.003) directions. These findings suggest that the SFP can be used in scientific investigations of balance in quiet standing. |

Para isso, três etapas foram estabelecidas: a) determinar o limiar de carga para chegar a um nível aceitável de exatidão da medida do centro de pressão (CP) pela aplicação de cargas pontuais; b) determinar a exatidão da medida do CP na aplicação de cargas distribuídas que simulam os pés humanos; c) verificar a validade concorrente da PFE comparando-a com uma plataforma de forças comercial (PF). Os testes das etapas “a” e “b” foram realizados pela aplicação de cargas sobre a PFE, utilizando uma máquina de ensaios universal. Na etapa de aplicação de carga pontual, a média do limiar de carga apresentado pela PFE foi de 315.6 ± 140.5 N. Os erros de medida do CP nos pontos próximos ao centro da PFE foram de 1.04 ± 0.80 mm na direção medio-lateral (ML) e 1.31 ± 0.99 mm na direção ântero-posterior (AP). Nos pontos próximos aos cantos da chapa, foram encontrados erros de 2.03 ± 0.91 mm (ML) e 1.54 ± 0.96 mm (AP). No teste com cargas distribuídas, os erros foram menores que 1 mm. Adicionalmente, não foram encontradas diferenças nos parâmetros do CP entre a PFE e a PF. O sinal do CP apresentou alta correlação entre os dois equipamentos, tanto na direção AP (r = 0.997 ± 0,001) quanto na direção ML (r = 0.988 ± 0,003). Os resultados sugerem que a PFE pode ser utilizada em estudos científicos do equilíbrio em postura ereta.Universidade Federal de Santa Catarina. Florianópolis, SC.
