The static sEMG scanner comprising at least two sets of measuring electrodes extending from the static sEMG scanner, the at least two sets of measuring electrodes configured and arranged for placement against patient skin in lateral proximity to the patients spine during operation of the static sEMG scanner, wherein each measuring electrode of the at least two sets of measuring electrodes is disposed a fixed distance apart from the remaining measuring electrodes of the at least two sets of measuring electrodes and at least one ground configured and arranged for placement against patient skin away from the at least two sets of measuring electrodes, wherein the at least one ground is retractable to facilitate maintaining placement of the at least one ground against patient skin during operation of the sEMG scanner. 7319340 1
