Qualitative conditional assessment of human limb using force masking technique with a strain gauge setup

Abstract

This The M curves, force vs. phase curves for gait analysis, are utilized for obtaining variation of voltage output during different stages of the gait cycle. The proposed method in this paper suggests a novel technique by calibration of the voltage and draws an inference on the health of human limb. The linearized calibration curve of the low hysteresis measuring instrument, is taken to our advantage in this measurement technique. An equivalent interpretation is arrived at from the voltage variation pattern analogous (proportional) to the load pattern. Ultimately comparative condition monitoring is performed using the voltage level as the new parameter to differentiate between a healthy and an unhealthy limb.
