Due to its relative amplitude character which is influenced by local detection conditions and the lack of normative curves or activation levels, the comparison of EMG findings is the most important strategy to analyze and interpret EMG data. Whenever you plan an EMG experiment or test, try to also plan reasonable comparison conditions right from the beginning. It is especially helpful to compare EMGs from the same muscle site in different movement phases, portions of the record or test activities: These analyses don’t require any amplitude normalization (see Analysis question level 2: more or less). It is probably the most important EMG design at al
