Design of the wearable device for hemiplegic gait detection using an accelerometer and a gyroscope

Hemiplegic walking is the main symptom of hemiplegia and is the basis for judging the outcome or severity of hemiplegia. In this study, we developed a wearable measurement module for measuring the inertia signal generated during walking and evaluated the possibility of gait measurement as a basic study of the new hemiplegia diagnosis technology using wearable device. The developed measurement module is worn on the waist. It is equipped with 3-axis acceleration sensor and 3-axis angular velocity sensor and has the function to transmit and record data through wireless communication. As a result of measuring the gait signals using the developed measurement module, specific patterns are shown for each axis according to each step, and it is confirmed that gait signals can be distinguished intuitively.
