Real time biofeedback mechanism and data presentation for knee injury rehabilitation monitoring and a soft real time intelligent system thereof

Abstract

A real time visualization method and system for evaluating and monitoring recovery progress of Anterior Cruciate Ligament reconstructed / injured subject is provided. The method includes receiving multiple super-imposed bio-signals from an eletromyogram (EMG) for muscles of limbs of the patient and signals pertaining to three dimensional kinematics measurement from a motion sensor set, processing the signals to extract wavelet features and evaluating the wavelet features to determine the extent of rehabilitation and a recovery classification of the patient's limb from ACL injury. The system includes an input interface circuit, a processing module, a comparator module and an output interface circuit for providing an estimate of the extent of rehabilitation the patient's limb from ACL injury.
