The invention discloses a
gait acquisition and neuromuscular electrical stimulation
system based on multi-
sensor fusion, and belongs to the field of
rehabilitation engineering. The
system comprises anelectromyographic
signal acquisition sensor module, a stimulation module, a
wireless transmission module and an upper
computer module, wherein the sensor module comprises a surface electromyographicsensor, a
laser ranging sensor and an inertial sensor. According to the invention, surface electromyographic signals,
Euler angles, angular velocities and accelerations of lower limbs and the distancefrom ankles to the ground during walking can be subjected to real-time
wireless acquisition and transmission, and are sent to the upper
computer module for calculation and
processing. According to the invention, electrical stimulation
modes and parameters of
lower limb functional action and recurrence of
healthy individuals can be obtained, and a control sequence of fine actions is studied; and aiming at a
gait disorder user, an
ankle-
foot orthosis is matched, and an autonomous optimization control stimulation scheme is realized by utilizing myoelectricity and
kinematics information, so thatthe aim of reconstructing a personalized movement function is fulfilled. According to the invention,
wireless receiving and
processing of data can be carried out based on a mobile terminal, and portability and practicability are improved.
