ABSTRACT
Objective To study the best method for myoelectric feedback training and evaluate the effectiveness of myoelectric artificial hand. Methods Fourteen cases of upper limb amputees (11 male, 3 female, aged 25?8.69 years, right side 13, left side 3,totally 16 myoelectric artificial hands) were recruited for this study. The biofeedback training process was divided into three steps: basic signal of myoelectric feedback training, visible feedback training, and ADL function training. Results After the training, 16 myoelectric artificial hands could grasp, pinch and rotate wrist, and could perform ADL such as dressing, eating, cleaning. Conclusion To achieve the goal set for the myoelectric artificial hand, emphasis should be on locating the most stronger myoelectric signal of the stump and strengthening the feedback training.
