It has come to the attention of the SESNA board that at least 3 different abbreviations for surface electromyography (sEMG, S-EMG, and SEMG) can be found in books and journal articles. After a debate, with input from the surface EMG section membership, the SESNA board has recommended that SEMG become the standard abbreviation and be used in all future books and articles on surface electromyography.

New and upcoming research

SESNA/SEMG Research Jeffrey E. Bolek, Ph.D. Current research is supported by a $100,000 grant from the Lennon Foundation to fund an outcome study of 70 children post-treatment in the Motor Control Program at the Cleveland Clinic Children's Hospital for Rehabilitation in Cleveland, Ohio. Children referred to the program have been in physical or occupational therapy and have either stopped progressing, have behavior issues that interfere with treatment or are having difficulty finding the right muscles to use to make functional gains. This program uses a new approach to deal with the problem of normalization of scores when treating children. It also uses protocols that were designed specifically to address the functional changes desired as a result of therapy, specifically, standing balance training, treadmill gait modification, reciprocal crawling, minimax sitting modification, and tonic muscle activation. The study has a target population of children ages 2 through 18 with cerebral palsy, stroke and acquired/inherited motor dysfunction.
