Lower-Extremity Spasticity during Standing Up Movements: A Case Study

The function of lower-extremity rehabilitation robotics usually includes standing up movements. These standing up movements can cause spasticity in people with disabilities of the lower extremities. In this paper, we review the spasticity and the methods of existing systems for handling the spasticity of people with physical disabilities. We observe and detect the spasticity via the EMG signals of the lower extremities of a subject with paraplegia. Through this process, we are able to suggest ways to deal with risk factors, such as spasticity, when using rehabilitation robots.
