Spinal transcutaneous stimulation is a non-invasive technique used to activate structures of the spinal cord and facilitate recruitment of the skeletal muscles after spinal cord injury. Electromyography is a non-invasive technique used to study muscle activation. The electrical current produced by spinal transcutaneous stimulation penetrates soft tissues and reach the nerve fibers to contaminate electromyographic signals and compromise the study of muscle activation. We developed a new methods to remove artifacts from the electromyographic signals so that researchers/clinicians can study muscle activation in individuals with a spinal cord injury who receive spinal transcutaneous stimulation.
The aims of this study are to characterize the contamination of EMG signals by artifacts generated by the delivery of spinal cord transcutaneous stimulation (scTS) and to evaluate the performance of an Artifact Adaptive Ideal Filtering (AA-IF) technique to remove scTS artifacts from EMG signals.
