Powered Gait Orthosis, Paraplegics, Electronic Walker,Gait Analysis
In this study, we developed an electronic walker that
controls the walking speed and assistive PGO(Powered
Gait Orthosis) gait using bio-signals and an FSR sensor.
In order to automatically control the electronic walker
according to the walking speed of the patient, an
algorithm was devised to use the feedback from an EMG
signal and COP .
The driving system of the EW(Electronic Walker)
PGO system consists of the PGO and electric walker
system. The role of this system is to provide constant “air
muscle” with compressed air at the hip joint. Controlling
method was used to control the moving speed of the
The results showed that the patients and the walker
could work together with stability when walking.
