The Design Of Rehabilitation Training System About Upper Limb Based On SEMG

The human upper limb hemiplegia,caused by the disease or accident in our reality life,that is an important impact on physical movement.According to data statistics,the increase of upper limb dysfunction is due to the stroke patients.After treatment with medical and drug,It will be left some different problem about the upper limb movement disorder.It is an indispensable part of daily life for hemiplegic patients,who with partial exercise capacity to do rehabilitation training.The traditional upper limb rehabilitation training is based on medical equipment,which rehabilitation training is under the guidance of rehabilitation physicians.Patients can not be fully into the process when they do rehabilitation training.In the traditional rehabilitation,The upper limb hemiplegia patients usually take repetitive action training with the upper limb rehabilitation robot.It is fatigue and boring for the patients,that is not achieving good rehabilitation level.For this situation,to improve the patient's subjective initiative,we designed a virtual system based on rehabilitation robot,To assist patients take rehabilitation training.This study is based on human anatomy and kinematics,It is different groups of muscle characteristics when the body take different movement.Combine with the rehabilitation theory.for example,task therapy or recreational therapy and exercise therapy.The design of upper limb rehabilitation virtual system,with the Immersion,Conception and Interaction.In this research,To prove the muscle characteristics with the upper limb electromyography experiment.And the muscle fatigue time is calculated by the IEMG of the SEMG,it is appliedto the rehabilitation virtual system as a time parameter,to prevent patients take excessive rehabilitation training.In this study,not only achieve the specific muscle for specific training in three-dimensional virtual system,but also achieve a multi-directional movement in the virtual training system,Through control the box and red wolf by the rehabilitation robot to take the rehabilitation training.Through the human-computer interaction technology,combine the rehabilitation robot with virtual system.At the same time,we can adjust impedance parameters of the upper limb rehabilitation robot,to provide varying level help,so that improve the efficiency of rehabilitation upper extremity hemiplegia.
