Acquisition of Lower Limb Joint Variables by an Inertial Card System

Abstract

Abstract-The high cost and low portability of joint variables acquisition systems that are commercialy used nowadays, make this technology usually unavailable for the rehabilitation of orthopedic problems in the lower limb. This work searches implementing a more economic, portable and efficient alternative for this kind of instrumentation, by using commercial inertial cards (IMUs: Inertial Measurement Unit) and the Lab-VIEW software for registering the joint variables related to knee and ankle during human gait.
