REALTIME BIOFEEDBACK MECHANISM AND DATA PRESENTATION FOR KNEE INJURY REHABILITATION MONITORING AND A SOFT REAL TIME INTELLIGENT SYSTEM THEREOF
First Claim
1. A method implemented by a real time visualization system for determining extent of rehabilitation and recovery classification of a knee joint of a patient'"'"'s limb from Anterior Cruciate Ligament (ACL) injury, the method comprising the steps of:
- receiving data pertaining to an activity from an activity set, the activity being performed by a patient, the data comprising;
multiple super-imposed bio-signals from electromyography (EMG) sensors placed on one or more muscles of one or both limbs of the patient, the one or more muscles including vastusmedialis, vastuslateralis, semitendinosus, biceps femoris and gastrocnemius; and
motion-signals pertaining to three dimensional kinematics measurements obtained from a motion sensor set;
processing the bio-signals from the EMG sensors and the motion-signals pertaining to three dimensional kinematics measurement to extract wavelet features; and
evaluating the extracted wavelet features to determine an initial estimate of the extent of rehabilitation and the recovery classification of the patient'"'"'s limb from ACL injury.

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.
