A portable measurement system for the evaluation of human gait

A tool has been developed which can be used to evaluate human gait in a more detailed manner. Its purpose is to record data from an individual during gait then categorize and analyze the intrinsic phases with neuro-fuzzy techni(TRUNCATED

On-line simulation tool for the design and analysis of lower-limb prosthetic devices

This paper presents a new and practical simulation interface to design and analyze lower-limb prosthetic devices. The proposed tool simulates the gait of a lower limb amputee using a desired prosthetic device. It allows the analysis of simple passive devices or the testing of control algorithms for active prostheses. The results presented in this paper correspond to the use of this tool to test a Fuzzy Controller specially designed for an active transfemoral prosthesis. To validate the tool, the simulation results are compared with "real-life" experiments

Comparison of different fuzzy controllers for powered prosthetic gait

This paper compares the fuzzy controllers trained with three different data-based methodologies for the control of the active knee joint of a powered transfemoral prosthesis. For each methodology a different inference system structure and number of generated rules was produced. The control is optimized using adaptive Neuro-Fuzzy optimization techniques and it is aimed to work at different speeds within normal gait

Implementación de un control basado en reglas a nivel coordinación para un caminado simétrico con una prótesis transfemoral activa

Abstract in SpanishEl control basado en reglas (RBC - Rule-Base Control) para un cami-nado “normal” de una prótesis transfemoral fue desarrollado para suimplementación en un microcontrolador. Se presentan las ventajasal utilizar este tipo de control sobre métodos analíticos, así como los resultados obtenidos de los análisis del ciclo de marcha, la genera-ción de reglas, la estructura de programación y las conclusiones más importantes que se obtuvieron en el trabajo realizado en [1,2] en la Universidad de Aalborg (Dinamarca) en el Departamento de Control en colaboración con el Center for Sensory Motor Interaction (SMI) de la misma Universidad.A Rule Based Control (RBC) for “normal” walking of a TransfemoralProsthesis (TFP) was developed for its implementation in a microcontroller. The advantages of using this type of control over analytical methods are described, as well as the results obtained in the Gait Cycle Analysis, the rule generation, the programming structure and the most relevant conclusions obtained in work realized in [1,2] at the Control Department of Aalborg University (Denmark) in collaboration with the Center for Sensory Motor Interaction (SMI) of such University
