Given the large variability of pathological gait and the high specificity of gait phenotypes, it is very difficult to design a gait rehabilitation system able to adapt to the functional requirements of every person with ambulation disabilities, in every stage of the complex process of gait rehabilitation. Another approach is that of ambiental gait rehabilitation, with focus on adaptability, not on adaptation, on synthetical training, not on analytical training, on integrative training, not on step by step training. Our focus is not on controlling the movement itself, but on controlling the environment that shapes human functionality and assuring the appropriate level of support, resistance and persuasion, with consequent stimulation of the explorative behavior and the active involvement of the person in gait training. A mechatronic system designed for such a therapeutical approach has specific functional requirements.

This paper presents a new methodology entitled AVTRIZ by its author, which allows technical, economic and managerial innovation based on the forecasting approach, while operating inside various systems. As the foundation of the new methodology, a classical method was chosen, well-known and widely applied that is the Method of Value Analysis and Engineering, a domain where the author has previous concerns. Starting from the fact that this method is deficient in terms of generating improvement solutions, the author searched and identified a method of current interest and global opportunity that is the TRIZ method [1], which is a method of wide debate, very controversial in terms of its adaptability from the technical to the business and management domains. On the other hand, TRIZ is deficient in terms of checking the solutions, a fact which can be successfully compensated by the Value Analysis Engineering method. Based on the above-mentioned approach, the research activities carried out by the author have brought in a new methodology, which is structured on 3 steps, 8 stages and 30 phases, based on the method of Value Analysis and Engineering, while also applying the TRIZ method.
