NMES Measurement Level I & II
The NMES-device display the current used for the selected stimulation in NMES-levels ranging from 0 to 999, which in a non-linear pulse duration dependent fashion correlate to current amplitudes ranging from 0 to 120 mA. The formula to calculate this correlation may be obtained from the manufacturer (DJO Nordic, Malmoe, Sweden) upon reasonable request, but may not be publicly distributed.When testing the two electrode setups, outcomes were registered at two distinct current intensities, designated Since ML I and ML II could occur at different NMES-levels for different participants, correlating non-linearly to different mA amplitudes for different participants, we deemed the presentation of the testing procedure in mA amplitudes to be too unpractical to be easily reproducible in a clinical setting, since it would require the user to obtain the conversion formula and convert the mA amplitudes back into NMES-levels. Thus, only the NMES-levels are used to describe the different current intensities during the testing procedure, while the current intensities in the results are presented in mA for better relative comparisons in the statistical analysis. The range of increase in current between ML I and ML II is disclosed in the results section.
