This document discusses quadriceps inhibition, including its causes and treatment using electrotherapy. It begins with an overview of quadriceps anatomy. Common causes of quadriceps inhibition include fractures of the femur, meniscal injuries, traumatic knee synovitis, and soft tissue injuries around the knee. The treatment procedure involves examining and preparing the patient, setting up the electrotherapy apparatus, placing electrodes on the thigh, and administering a current to contract the quadriceps muscle and reduce inhibition. The treatment is administered with the patient in a half-lying position with the knee flexed at 15 degrees.

5. Quadriceps inhibition
• Due to fear of pain
the patient cannot
contract the
quadriceps. Hold
the muscle in a
tensed position;
extension of knee
is limited

6. Causes
• Fracture shaft of femur
• Menisectomy
• Traumatic synovitis of knee
• Surgical intervention
• Soft tissue injury around knee
• Post operative (i.e.) after arthroscopy

12. Treatment
• Position of patient: Half lying
with knee supported in 15
degree flexion
• Current parameter: FTC (8-10
surge/min)
Intensity : max intensity to
produce muscle contraction
Duration : 10 minutes ( until
muscle get fatigue)

( carbonized rubber electrode)
Active : middle 1/3 rd of thigh
Inactive : lower 1/3 rd of thigh
