Outline of Final Research Achievements

Variety of prosthetic ankle foot systems have been developed and commercially available. Their characteristics have been explained not by mechanical data. Recently, ISO standard has been published and it became possible to get the mechanical property based on this standards. On the other hand, the user's evaluation have been made through their subjective reports. In this research, the metabolic measurement and the infrared spectroscopy to measure the blood flow on the brain surface were used. The research investigated the relation between the mechanical data and the objective data obtained from the users using the prosthetic feet. As a result, it became possible to compare the mechanical property through the standardized data. The relation between the mechanical property and the user's objective data could be connected in some level. It is considered that if we gather more data, it may be possible to estimate the users response from the objective data.
