Various studies ^1,3,5 have shown that electrical stimulation with the NESS H200 reduces complications.

The graph below taken from one of these studies illustrates the significant reduction in pain.

The x-axis shows the point in time that the measurement was taken, while the y-axis shows the pain score based on a standardized questionnaire. Various studies have shown that pain is reduced by over 46% on average.
