Normative Data for Paraspinal Surface Electromyographic Scanning Using a 25-500 Hz Bandpass
Abstract
A protocol has been previously described for recording surface paraspinal electromyographic (SEMG) potentials at fifteen paired sites (4 cervical, 7 thoracic, 3 lumbar, 1 sacral) using a bandpass (range of sampled frequencies) of 100 – 200 Hz. In this paper, normative data from eighty human subjects are presented using this protocol and a 25 – 500 Hz bandpass.The advantages of a 25 – 500 Hz bandpass are discussed.
