Abstract

After a stroke, muscle spasms will occur randomly, which will result in failure of normal training. To ensure the safety of the training process, rehabilitation training equipment must have the function of spasm detection and related processing mechanism. In this paper, a method for detecting spasms based on motor current is proposed. The calculation process is given. The spasm is detected when the average motor current and its duration exceed the pre-set value. The sensitivity of spasm detection can be set by setting different current and duration pre-set values. This method is used in the active and passive rehabilitation training system for upper and lower limbs, which passed the safety test and got the NMPA permission. This system has been used in hospitals and nursing homes for more than 1,000 hours. This method has been proven to be effective according to the safety test and applications.
