Identifying changes in human skin electrical properties due to long-term NeuroMuscular Electrical Stimulation

The skin electrical properties are identified using a standard NeuroMuscular Electrical Stimulation (NMES) voltage pulse. The three component series equivalent electrical model was chosen to account for the skin electrical properties. The values of each of these three electricel components of the equivalent electrical model were identified and compared throughout 40 minute daily NMES sessions and over 5 days. Current measurements were performed during the NMES sessions in a non-invasive way, in order to assess changes occuring during each stimulation session and due to long-term NMES.
