This paper presents a self-adaptive software for efficiently generating personalized lower-limb rehabilitation mechanisms, which based on patients’ parameters such as height, thigh length, shank length and gender. The proposed system utilizes clustering method and the GA-SVM classifier to predict the optimal standard gait trajectory for patients, combined with a GA-BFGS hybrid optimization algorithm to determine the geometric parameters of a 1-degree-of-freedom (DOF) six-bar mechanisms which can best similarize the target trajectory. The innovation of this paper is in its use of clustering method to map a vast amount of disordered user trajectories to a limited set of standardized trajectories, thereby enabling user-to-institution matching. Featuring an intuitive interface, the software integrates trajectory recommendation, mechanism synthesis and motion visualization into a unified workflow, thereby enabling the generation of patient-specific rehabilitation mechanisms for diverse anthropometric characteristics. Experimental validation demonstrates that the synthesized mechanisms achieve an average trajectory deviation of 8.2 mm, confirming the software’s clinical applicability in personalized rehabilitation.
