1. An apparatus for determining a degree of restoration of a diseased part, comprising:

  • a plurality of pairs of electrodes;

    an electric current source;

    a voltage measuring unit;

    an arithmetic unit;

    a storage unit; and

    a comparison unit;

    wherein said electrodes are for contacting the skin of a user in the area surrounding the diseased part, said electric current source feeds a measuring current via one selected pair of electrodes of said electrode pairs, said voltage measuring unit measures a voltage between another selected pair of electrodes of said electrode pairs, said arithmetic unit calculates an index of swelling in the area surrounding the diseased part representing a degree of restoration of the diseased part based on the measurement data from said voltage measuring unit, said storage unit stores the index of swelling in the area surrounding the diseased part produced by said arithmetic unit as a reference value, and said comparison unit compares the reference value stored in said storage unit with a current index of swelling in the area surrounding the diseased part to determine a degree of restoration of the diseased part.
