         [0003]     2) Description of the Prior Art  
         [0004]     Of the electrotherapeutic models observable at present, most are outdated legacy approaches, often low frequency electrotherapeutic methods that are only capable of electrically stimulating shallow regions of the human body, with such conventional low frequency machines typically having the following shortcomings: 
        1. Electric impact stimulation: Overly intense, tingling sensation, and only in shallow flesh regions.     2. Wave form rigidity: Inflexible and cannot be adjusted to accommodate the greater or lesser resistance of each person.     3. Acute wave form: Shallow level, slow pulse wave speed, cannot sense skin pain or nerve irritation, and stinging sensation.     4. High saturation: No anti-weighting space, harsh.     5. Electrical discharge slow: Absorption too gradual, slow to reach afflicted area, sluggish pulse wave speed results in excessive nerve pain and unbearable stinging.     6. Increased pressure multiple too high; the higher the voltage, the less suitable for the human body.
