The upper limb function training and assessment system plays a crucial role in clinical applications. It provides patients with upper limb torque assessment, strength change curves and real-time biofeedback for those with upper limb dysfunction. This system, through functions such as motion monitoring, action guidance, action assessment, training games, data recording and analysis, helps patients undergo upper limb rehabilitation training. It can also output clinical reports, which can be analyzed to facilitate the assessment of patients' recovery status by medical staff and the formulation of treatment plans.
