The invention discloses a rehabilitation training system based on cloud computing. The rehabilitation training system based on the cloud computing comprises a data acquisition module, an evaluation analysis module, a network communication module, a simulation training model, a database module, a system use role management module and an information management system module, wherein the data acquisition module uploads acquired data to a local PC (personal computer) through the network communication module, and then is connected with a server on the Internet. The rehabilitation training system based on the cloud computing has the advantage of using powerful knowledge resources, computers, networks and modern sensing systems in a hospital, remotely acquiring, processing and transmitting training data in real time, enabling a patient to stay at home, perform rehabilitation training whenever and interact with a doctor who sets an example for the patient and guides the patient in the training whenever, greatly facilitating the patient, not only simulating interesting training, but also guiding and controlling the training process and the training scheme according to physiologic feedback information, and significantly improving effects of the rehabilitation training.
