Abstract
AbstractAs the number of patients caused the stroke increase, there are many therapies applied to rehabilitation, but they lack scientific theoretical basis guidance. In the process of treatment, the muscle force analysis, and the movement of information to predict muscle activity, they can provide a theoretical basis for the design of rehabilitation exercise; the treatment is more targeted and efficient. According to the characteristics of upper limb motion, this article establishes a reasonable and effective mathematical model, and uses the Hill muscle model to establish the simplified musculoskeletal model. The simulation model of human upper limb is used to establish with anybody software. The subjects have an experiment with the elbow joint flexion and extension, and use the electromyography collection device to collect the sEMG of biceps brachii and triceps brachii. And the motion information is processed to obtain the motion angle, angular velocity and angular acceleration. After preprocessing the ...
Highlights
In recent years, the cases of dyskinesia patients increased year by year, and they are mainly caused by strokes
The results show that the EMG signal can directly reflect the muscle force
In order to confirm the relationship between sEMG and motion information and muscle force
Summary
The cases of dyskinesia patients increased year by year, and they are mainly caused by strokes. Passive movement refers to the patients have some simple exercises with the help of the instrument or nursing staff It can stimulate the lateral muscle, and make for the function recovery of limb. This article selects the motion of elbow flexion and extension as the research object in the upper rehabilitation therapy. Develop a targeted musculoskeletal model, dynamic simulation is done on strokes patients, these have not been used and researched. The musculoskeletal model of elbow joint The human movement system is composed of bone, bone connection and skeletal muscles. The movement characteristics of elbow joint The upper limb is a very complex structure, especially the palm part, the structure is complex and the activity is very flexible, the related research aimed at the palm part is enormous.
