Muscle Extremely Low Frequency Magnetic Stimulation Eliminates the Effect of Fatigue on EEG-EMG Coherence during the Lateral Raise Task: A Pilot Quantitative Investigation

Table 1

Summary of EEG-EMG coherence area of different electrode, separately for different force loads, for the fatigue/nonfatigue status, and with/without ELF stimulation. The data is presented as mean±SD.
