Abstract

Recently, functional electrical stimulation (FES) has been applied for the treatment of the shoulder subluxation. The purpose of this study is to design a musculo-skeletal dynamic model for hemiplegic shoulder subluxation with which can perform FES effectively as well as the simulation of shoulder motion by FES. We installed the muscle models into the skeletal model. In this model, scapula and clavicle are fixed, and only gleno-humeral joint can move. We set up muscle activation, and stimulate deltoideus and supuraspinatus. As a result of simulation, we can confirm the reduction of shoulder subluxation.

FES治疗肩关节半脱位的模型模拟
近年来,功能性电刺激(FES)已被应用于治疗肩关节半脱位。本研究的目的是设计一个偏瘫肩关节半脱位的肌肉-骨骼动力学模型,该模型可以有效地执行FES,并通过FES模拟肩关节运动。我们将肌肉模型安装到骨骼模型中。在这个模型中,肩胛骨和锁骨是固定的,只有肩胛-肱骨关节可以活动。我们设置肌肉激活,刺激三角肌和冈上肌。作为模拟的结果,我们可以确认肩部半脱位的减少。
