<qa>  What is the spectral peak of 4-7 Hertz at the sternocleidoEMG spectral analysis for the auto-spectral peak of 4-7 Hertz Hz at the sternocleidomastoid SCM and the 10-12 Hz coherence between the SCM and the splenius capitis SPL will be used at the time of peak BoNT ON and trough BoNT effects BoNT OFF.
