Study of the Effectiveness of an Analgesic Electrostimulation Session (Invasive and Non-invasive) Applied on the Femoral Quadriceps Muscle in Patients Who Have Undergone an Anterior Cruciate Ligament Surgey: A Random Clinical Trial

Application of a single session of non-invasive analgesic electrostimulation to motor points of the vastus medialis and vastus lateralis of the quadriceps femoris muscle in patients who have undergone an anterior cruciate ligament reconstruction. A biphasic, symmetrical, square-wave current was applied at a frequency of 100 Hz, a pulse width of 200 μs, and an intensity adjusted to the patient's pain threshold for 30 minutes.

Application of a single session of invasive analgesic electrostimulation to a motor point of the vastus medialis of the quadriceps femoris muscle in patients who have undergone an anterior cruciate ligament reconstruction. A biphasic, symmetrical, square-wave current was applied at a frequency of 100 Hz, a pulse width of 250 μs, and an intensity defined as perceptible to the patient but never painful (200 μA above the detection threshold for each subject).
