CHAPTER FOURTEEN. Electrical Stimulation

The mechanism of attracting cells to a specific area using electromagnetic fields is termed

a. Chemotaxis

b. Electrotaxis

c. Current of injury

d. Electrocautery

In order to have optimal migration of cells to the wounded area, it is advised to

a. Have the electrodes of equal size and 15 cm apart

b. Have the active electrode distal to the wound and the dispersive proximal to the wound

c. Have the dispersive electrode twice the size of the active electrode and place the electrodes 10 to 15 cm apart

d. Have the active electrode over the wound and the dispersive electrode as far away as possible

The intensity or voltage of the current is advised to be

a. As high as the patient can tolerate

b. Equal to what the patient can tolerate on the opposite extremity

c. High enough to see visible fasciculations

d. High enough for the patient to feel a slight tingling sensation under the electrode

An absolute contraindication for the use of electrical stimulation to treat a wound is

a. The patient has a pacemaker.

b. The wound is suspected of having infection.

c. The patient is insensate.

d. The wound has been epithelialized for 1 week.
