This is with regards to the electrical stimulas pulses which arrive to the abs sites via electrodes and electrode jell. I understand that there is a patent on the particular pulse width and its modulation characteristics, and I even found a number of related patents (swiss-wave), etc. , however, and this is just my opinion from the cheep seat that I sit, 'it seems to me that the stimulation of any muscle and/or grouping of muscles would be best accomplished via the nerve networks comming from the inside pathways, and not necessarily from the surface of the skin.
