Human-Machine Coupled Modeling of Mandibular Musculoskeletal Multibody System and Its Applications in Quantitative Rehabilitation

EasyChair Preprint 13548

Abstract

About 44.1% of the patients suffering from oral and maxillary tumors had trismus syndrome (restricted mouth opening) six months after mandibulectomy. Patients with restricted mouth opening can use mandibular movement function trainer (MMFT) for jaw-opening training. However, existing MMFT cannot consider individual mandibular movement characteristics. Mandibular musculoskeletal modeling can reveal the patient-specific muscle recruitment patterns and temporomandibular joint (TMJ) impedance during jaw opening. In this paper, a human-machine coupling model was established based on flexible multibody dynamics, and it was further utilized to design the MMFT auxiliary forces of each patient.

Keyphrases: human-machine coupling, mandibular, musculoskeletal model, trismus
