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.
