Abstract: Objective To develop a rehabilitation device and software game, and provide the system for evaluation and training of anterior cruciate ligament (ACL) reconstruction.MethodsThe development and clinical application of a biofeedback knee joint movement rehabilitation system for ACL reconstruction were very important.ResultsBIOKS readings reproduce Zebris 3D motion analysis system measurements reliably between 0° and 150° ( P>0.05). Significant knee joint movement training effect ( P<0.05 ) in JPS assessment. However, there were no differences ( P≥0.05) between SST and KAS assessments.ConclusionThe improvement of joint position sense and body centroid sway under single leg support conditions.

Key words: anterior cruciate ligament reconstruction, knee joint, position sense, biofeedback
