Clinical Trial Controlled Clinical TrialClinical considerations in the use of surface electromyography: three experimental studies.
The validity and applicability of erector spinae electromyogram (EMG) use in clinical practice is questionable. Differences in the amplitude of the EMG signal between populations with low back pain (LBP) and controls have been hypothesized but not sufficiently documented. ⋯ Repeatability of the EMG signal during quiet stance is acceptable; however, bilateral asymmetry may not be a definitive indicator of dysfunction.
