The system includes a tool including a handle portion and a skin engagement portion that is configured to generally match the contour of the impaired area of soft tissue to be treated. The tool is connected to a source of electrical current for providing electrical stimulation to the impaired area during treatment with the tool. The skin engagement portion noninvasively engages the skin to allow the user to locate fibrous adhesions that are attached to the underlying soft tissue areas. ## Claims ### Claim 1 A system for use by a trainer for loosening fibrous scar tissue adhesions from underlying soft tissue of a patient, comprising: an elongate rigid body having a first end and a second end, a first flat surface and a second flat surface opposite from said first flat surface, and a peripheral edge extending about the circumference of said body, wherein a portion of said peripheral edge is configured in the shape of an arc corresponding to the shape of a contour of a selected part of a patient's anatomy from which a scar tissue adhesion is to be loosened from the underlying soft tissue, wherein a second portion of said peripheral edge includes a tapered surface to define an edge, and wherein said body includes an electrical connector; and a source of electrical current connected to said body at said electrical connector for passing electrical current through said rigid body to the scar tissue adhesion of the patient. ### Claim 2 (depends on 1) The system of claim 1, wherein said arc shaped portion of said peripheral edge includes said tapered surface. ### Claim 3 (depends on 1) The system of claim 1, wherein said tapered surface comprises a beveled edge. ### Claim 4 (depends on 1) The system of claim 1, wherein said tapered surface comprises a blade edge. ### Claim 5 (depends on 4) The system of claim 4, wherein said blade edge is rounded to a 50.degree. radius or better. ### Claim 6 (depends on 1) The system of claim 1, wherein said electrical connector is positioned at one of said first and second ends of said body. ### Claim 7 (depends on 1) The system of claim 1, wherein said body is made of stainless steel. ### Claim 8 (depends on 1) The system of claim 1, wherein said source of electrical current is capable of providing electrical current in a plurality of waveforms. ### Claim 9 A method of loosening a fibrous scar tissue adhesion from underlying soft tissue of a patient, comprising the steps of: providing a massaging tool having a curvilinear skin-contacting portion generally matching the contour of the soft tissue; connecting said tool to a source of electrical current in such a manner that a stimulating electrical current passes through said tool; and electrically stimulating said adhesion while passing the curvilinear portion of the tool across the skin of the patient, said tool being passed across said skin in a manner to cause noninvasive contact of the skin-contacting portion of the tool with the scar tissue adhesion sufficiently to loosen the adhesion from the soft tissue. ### Claim 10 (depends on 9) The method of claim 9, including the step of lubricating the surface of the skin before passing the tool thereacross. ### Claim 11 (depends on 9) The method of claim 9, including the step of passing the tool across the skin sufficiently to determine the location of the fibrous adhesion on the soft tissue. ### Claim 12 (depends on 9) The method of claim 9, wherein said step of electrically stimulating includes manipulating the adhesion sufficiently to loosen the adhesion from the underlying soft tissue. ### Claim 13 (depends on 9) The method of claim 9, including the step of stretching the soft tissue to a maximum possible length after passing the tool across the skin, thereby increasing the range of motion of the soft tissue area. ### Claim 14 (depends on 9) The method of claim 9, wherein said source of electrical current is capable of providing electrical current in a plurality of waveforms. ### Claim 15 A method of loosening a fibrous scar tissue adhesion from underlying soft tissue of a patient, comprising the steps of: providing a massaging tool having a curvilinear skin-contacting portion generally matching the contour of the soft tissue; providing a source of electrical current; establishing an electrical connection by connecting said massaging tool to said source of electrical current via a cathode, and by connecting an anode to said source; positioning the anode in closely spaced relationship to the scar tissue adhesion by contacting a tissue adjacent to said scar tissue adhesion with said anode; and passing the curvilinear portion of the tool across the skin of the patient in such a manner to cause noninvasive contact of the skin-contacting portion of the tool with the scar tissue adhesion sufficiently to loosen the adhesion from the soft tissue and to transmit electrical current from said tool to said scar tissue adhesion. ### Claim 16 (depends on 15) The method of claim 15, including the step of lubricating the surface of the skin before passing the tool thereacross. ### Claim 17 (depends on 15) The method of claim 15, including the step of passing the tool across the skin sufficiently to determine the location of the fibrous adhesion on the soft tissue. ### Claim 18 (depends on 15) The method of claim 15, including the step of stretching the soft tissue to a maximum possible length after passing the tool across the skin, thereby increasing the range of motion of the soft tissue area. ### Claim 19 (depends on 15) The method of claim 15, wherein said source of electrical current is capable of providing electrical current in a plurality of waveforms, and includes means for selecting a desired waveform. ### Claim 20 (depends on 15) The method of claim 15, wherein said massaging tool comprises a first massaging tool, and wherein said method further comprises providing a second massaging tool, said second massaging tool being shaped differently from said first massaging tool, and thereafter repeating said method with said second massaging tool in place of said first massaging tool. ### Claim 21 A method of loosening a fibrous scar tissue adhesion from underlying soft tissue of a patient comprising providing a generally non-pliable massaging tool having a skin contacting portion, passing the massaging tool across the skin of the patient in such a manner to cause non-invasive contact of the skin contacting portion of the tool with the scar tissue adhesion for mechanically loosening the scar tissue adhesion, connecting the tool to a source of electrical current in such a manner that a stimulating electrical current passes through said tool; and electrically stimulating at least one of the underlying soft tissue and the scar tissue adhesion while passing the massaging tool across the skin of the patient for permitting the electrical stimulation to reduce the irritation caused by the scar tissue. ### Claim 22 (depends on 21) The method of claim 21 wherein the step of providing the massaging tool comprises the step of providing a massinging tool having a curvilinear skin contacting portion. ### Claim 23 (depends on 21) The method of claim 21 wherein the step of providing the massaging tool comprises the step of providing a massaging tool having a beveled edge. ### Claim 24 (depends on 21) The method of claim 21 further comprising the step of passing the messaging tool across the skin of the patient to locate the scar tissue adhesion.
