Performance Therapy — Quadriceps

Trigger points in the quadriceps muscles are commonly the cause of hip, thigh and knee pain The quadriceps is a large group of muscles, the most massive of the leg, located in the anterior (front) of the thigh. They originate from above the hip joint and extend to below the knee.

Rectus femoris is part of the quadriceps femoris, which also includes the vasti group: vastus...

Inflammation of the quadriceps tendon can be a result of repetitive stress to the quadriceps or excessive stress before the muscle is conditioned Minor tears may occur in the tendon when it is stretched while subjected to loading. Pain just above the patella (kneecap), especially when extending (straightening) the knee, usually accompanies this injury. Cause of injury Repetitive stress to the tendon, e.g. running or jumping. Repetitive acceleration and deceleration, e.g. hurdling or football. Untreated injury to the quadriceps.     Signs and symptoms Pain just above the patella. Jumping, running, kneeling or walking down stairs may aggravate the pain....
